Presentation on the topic of crop production in our region. Presentation on the world around "plant growing in our region". I. Organizational moment, communication of the topic and objectives of the lesson

Try to explain what "varieties of cultivated plants" are? Where did they come from?

Answer. Variety - a group of cultivated plants, united by certain economic characteristics. Varieties of cultivated plants are bred by plant breeders from cultivated wild plants.

With the help of a textbook, establish what branches crop production is divided into?

Answer. Crop production is a branch of agriculture that specializes in the cultivation of cultivated plants. Branches of plant growing - field growing, vegetable growing, fruit growing, floriculture.

What are the characteristics of crop production in your area? This can be found in local history literature. Think about how these features are related to the natural conditions of the region?

Answer. Agriculture of the Chelyabinsk region is a branch of the economy of the Chelyabinsk region, engaged in the production of agricultural products.

Features of the development of agriculture in the region depend on the characteristics of its climate and soil cover. The Chelyabinsk Region is located in the Southern Urals in the center of Eurasia. Large areas are occupied by crops. This is facilitated by fertile chernozem soils and climatic conditions - warm and enough rainfall.

Branches - field cultivation, vegetable growing, fruit growing, floriculture.

Choose one of the branches of crop production. Get to know her in the textbook and local history literature.

Complete the tasks in the workbook related to this industry.

Answer. Field farming is the most important branch of crop production in which field crops are cultivated. It provides the population with basic foodstuffs, animal husbandry - feed, light and textile industries - raw materials.

People of many professions work in field farming: agronomists, agronomists-seed growers, agrochemists, machine operators, and others.

A tractor driver of a wide profile is the most common profession in field farming. The tractor driver must know perfectly not only agricultural machinery, but also the methods of cultivating plants, their biological characteristics. He must be able to carry out maintenance and repair of agricultural machinery.

According to the purpose of the products, economic characteristics and characteristics of cultivation, field crops are divided into groups6 of cereals, legumes, oilseeds, spinning, fodder.

Forage grasses are grown for livestock feed. They belong to two botanical families: cereals and legumes. According to their life expectancy, they are divided into annuals, biennials and perennials.

Herbs are of great agrotechnical importance. Legumes, thanks to symbiosis with nodule bacteria, enrich the soil with nitrogen. Cereals, having a powerful root system, contribute to the accumulation of organic matter in the soil. Forage grasses improve soil structure.

Homework assignments

1. Write down in the dictionary the names of the branches of crop production that are developed in your region.

Answer. Branches:

field farming is the cultivation of field crops (wheat, rye, oats, corn, buckwheat, potatoes, flax, sunflower)

vegetable growing - growing vegetables (cucumbers, tomatoes);

fruit growing - growing fruit and berry crops (apple, pear, strawberry, cherry, plum);

floriculture - cultivation of ornamental crops. (chrysanthemums, asters, peonies, roses, hyacinths, gladioli).

2. If you live in the countryside, watch the spring work in the field, in the garden, in the garden. Take photos. Find out from adults what work has already been done and what remains to be done. Prepare to share what you learned and did with the class.

Answer. In the spring, the following work is carried out:

Cleaning is carried out from the fields of stones that are squeezed out by frost to the surface;

Loosening a strong crust on the surface of the earth. This will provide the necessary air exchange for the seeds;

Removal of stagnant water from fields. Excess moisture is detrimental to many crops, it leads to decay of the root system and can significantly reduce crop yields;

Cleaning of free land areas from moss, shrubs, alluvial sand;

First of all, replenishment of mineral and organic substances in the soil, fertilizing the soil with manure;

Carrying out measures aimed at preparing fields for sowing;

Cleaning, sorting seeds for sowing;

Soil sowing;

Plowing up the brought manure.

Simultaneously with these works, others are carried out, familiar to every gardener and gardener:

Fertile soils are developed with subsequent fertilizer;

Seedlings are sown in greenhouses, greenhouses, in open beds;

Seed plants, tubers are planted;

Trapping heaps are arranged (for the larvae of the May beetle).

3. Visit the greenhouse. Pay attention to how it is arranged, what plants are grown in it. If possible, get acquainted with the conditions of the greenhouse. How is it similar to a greenhouse and how is it different from it?

A greenhouse is a small mobile unheated structure designed for growing seedlings and protecting them from adverse weather conditions, followed by planting them in open ground.

A greenhouse is a heated structure in which you can organize the growth of plants throughout the year, from planting seeds / seedlings to harvesting.

The greenhouse has a more complex and robust design than a greenhouse. Often it is installed on a solid foundation, has walls and a roof made of polyethylene, glass frames or cellular polycarbonate. The greenhouse structure is much simpler, it is easy to build even for a non-professional. Often a greenhouse consists of a removable arched roof, which is a frame covered with plastic wrap. Less commonly, the greenhouse is covered with glass or polycarbonate.

In greenhouses, vegetable and flower crops are most often grown.

Recall what you learned about animal husbandry and animal husbandry professions by studying the natural areas of our country. What pets are bred in your area?

Answer. Animal husbandry is the branch of agriculture concerned with the breeding of domestic animals. In different natural areas, they breed different animals. This is envy of natural conditions. For example, deer are bred in the tundra, and camels are bred in the deserts.

In our region - the zone of steppes and forest-steppes, cattle and small ruminants, horses are bred. In our region there are large poultry farms where chickens, ducks, and turkeys are bred. Carp and trout are bred in lakes and ponds.

4. As instructed by the textbook (p. 193), observe the spring work in the field, in the garden, in the garden. Do the necessary work yourself. Write a short report about what you saw and did. You can draw or paste a photo.

This spring, I helped my grandmother plant onions in her garden. It was very interesting.

First we took a shovel and dug up the ground under the bed. Then we leveled the ground with a rake and formed a rectangular bed.

Then the grandmother took a stick and drew straight longitudinal grooves on the bed. It was in these grooves that we began to plant small bulbs, which my grandmother called “onion sets”.

Grandmother said that all the bulbs should be at an equal distance from each other. We deepened them a little into the ground and made sure that the root was always at the bottom, and the tail with a green seedling at the top.

Then we sprinkled the planted bulbs with earth and watered them well from a watering can. I hope our bulbs will germinate quickly and we will use them for cooking all winter.

IV. Working on a new theme.

Teacher's word. (Slide 6)

- In ancient times, primitive man was engaged in hunting and gathering. After all, in order to live, a person needs to eat. The success of hunting and gathering largely depended on the vagaries of nature: either a forest fire would destroy trees with edible fruits and drive away animals, or a drought would destroy the grass that gave people grains and roots ...

And, one day, women noticed that in the place where grains were usually ground on a stone grater, spikelets with the same grains grew. They guessed that it was randomly scattered grains that sprouted. We tried to deliberately scatter the grains - it turned out, and even how: where the grain fell, a whole spikelet grew, or even several. Now it was already possible to grow grains near the house, and not wander in search of forests and meadows. Years passed, man developed, agriculture improved, the plants that man grew became more and more diverse. Growing a good crop is not an easy task, for this you need to know a lot. Know when to plow the land, when to plant, water, what plants need for good growth, when to harvest ripened fruits.

– Cultivation is responsible for the cultivation of cultivated agricultural plants and their cultivation. Look in the dictionary, how does S.I. Ozhegov interpret the word crop production? (Crop production is the science of breeding cultivated agricultural plants, as well as such breeding itself.) (Slide 7)

– Crop production is divided into several main branches: field cultivation, vegetable growing, fruit growing and floriculture.

- In each region, crop production depends on natural conditions and has its own characteristics. (Slides 8-10)

- How did man make wild plants cultivated? He did not just grow plants near his house, but selected the best, preserved and propagated them. Many families have garden plots where they grow vegetables, berries, and fruits. Let's consider a simple example. People have harvested potatoes, and what's next? (Potatoes are taken to the cellar, sorted by size, selected for seeds for planting next year)

– And not just select, but take the best. Large potatoes are never left to seed. A good owner, relying on his experience, takes care of the future harvest. Laboratories and experimental stations are working on breeding new varieties.

- Let's talk separately about each branch of crop production.

Field farming. (Slide 11)

Think about what this industry does.

Children receive herbarium materials: wheat, rye, barley, oats, buckwheat, flax, their grains, corn, sunflower, potatoes. The work is carried out in groups.

Card Help. (Slide 12)

  1. The name of the group of plants according to the place of cultivation.
  2. What is obtained from each plant.
  3. How are grains different? (Slides 13, 14)

Discussion: These plants are grown in the fields, which means they are field crops. Flour is obtained from wheat and rye and bread is baked. These plants differ in the shape of spikelets; rye has long, hard whiskers of different heights. Rye is higher than wheat. Rye and wheat grains differ in shape but are similar in color. Oat grains are oblong, porridge is cooked from them. Buckwheat is distinguished by brown grains and an unusual shape. Buckwheat is obtained from it.

- And what is obtained from millet and barley? (Pearl is obtained from barley, and millet is obtained from millet.) (Slides 15, 16)

What is obtained from sunflowers? (Sunflower oil and seeds) (Slide 20)

- What about linen? (Linseed oil) (Slide 21)

“It's a very interesting culture. Linen fiber is obtained from flax. In the old days, canvases were woven from this fiber and clothes were sewn.

- What about potatoes? (He uses underground parts for food - tubers) (Slide 19)

- Starch is also obtained from potatoes. Love kissels?

– Field cultivation is engaged in cultivation of such crops.

– These field crops are grown at our state farm AgroSvet.

Vegetable growing. (Slides 22-24)

– What does this industry do? (Growing vegetables)

- Correctly. Vegetables are grown not only in the fields, but also in gardens, and even in greenhouses. What vegetables do you know? (Cabbage, cucumbers, zucchini, carrots, beets, onions)

Display of dummies and samples of cultures.

Vegetables play a huge role in human nutrition.

– Vegetables such as onion and garlic are able to kill pathogenic microbes because they contain phytoncides. It is no coincidence that they are recommended to be eaten raw during influenza epidemics. (Slide 25)

V. Physical education.

(Slide 26)

Tara-tara-tara-ra!
From the collective farm
Tractors are leaving.
Let's sow and plow
Plant seeds.

VI. Work on the topic.

Fruit growing. (Slide 27-29)

- Fruit growing is the cultivation of fruit crops that produce fruits. What fruit and berry trees and shrubs do you know? (Apple, pear, cherry, plum, raspberry, currant)

Floriculture. (Slide 30)

– You will read about floriculture on your own on page 206.

- Why are some flowers grown in open ground, others in greenhouses, and still others in a room? (In greenhouses and rooms, flowers are grown all year round. And in open ground, plants are grown that have time to bloom before the cold. Flowers are thermophilic and not very.)

The world of flowers is amazingly beautiful and diverse. Remember what beautiful flowers met us on September 1 and delighted us with their beauty.

Work in a workbook. (Slide 32)

S. 68 No. 1,2,3.

VII. Consolidation of what has been learned.

- List the branches of crop production. (Field growing, vegetable growing, fruit growing, floriculture).

What industries are developed in our region?

VIII. Game "Recognize the plant."

(Slide 32)

- Guess the plant and name the branch of crop production that grows it.

І. Organizing time

- Every day, always, everywhere

In class and play

Be bold, speak clearly

And sit quietly.

About our wonderful land,

Where we all live together

About a beautiful sweet land

Let's have our conversation.

- In the last lesson we talked about the life of a fresh water body.

II . Checking homework

Crossword questions:

    A plant with floating leaves and yellow flowers. Listed in the Red Book.

    The animal is a rodent, swims well, builds dams, its tail looks like a shovel.

    Baby frog.

    A plant with arrow-shaped leaves with large broad tips.

And the entrance to the mink is in the water

    A plant often referred to as bulrush, with a soft brown tip on the stem.

Keyword:Swamp.

Alignment of students' knowledge (frontal work).

    Tell me, is it necessary to protect the swamps?

    Prove with examples that a reservoir is a natural community.

    Tell us about the rules of behavior at the reservoir.

    What problem do fresh water bodies of our region, country solve? (they are the keepers of clean water, they solve the problem of clean fresh water)

    - How to solve this problem? (to protect, not litter rivers, lakes, ponds, to preserve the natural communities of water bodies)

    - Nowadays, the problem of clean fresh water is one of the most important, because fresh water is needed by animals, people, and plants.

ІІІ. CREATING A PROBLEM SITUATION.

    Consider objects (pictures depicting fruits, vegetables, trees)

    What are these items? What common? (these are plants)

    What is different about them? (some are fruits, others are vegetables, others are trees).

    Are there any other differences? (some will answer NO, others will say that there are plants that people grow, but there are wild plants)

І V .MESSAGE TOPICS AND OBJECTIVES OF THE LESSON.

    Do you think humans can live without plants? (they put forward a hypothesis: the plant world is inextricably linked with man, it is impossible to do)

    Today in the lesson we will learn how cultivated plants appeared, get acquainted with the branches of crop production.

    For what? (we will learn to distinguish cultivated plants according to their characteristic features).

    And we will also find out whether our hypothesis was correct.

V. WORK ON NEW MATERIAL (operational-executive stage)

The following items are on the tray: carrots, potatoes, buckwheat, white bread, black bread, sunflower oil, an apple, a pear.

    Guys, what do all these items have in common? (You can eat. All this is given by plants).

    And why, at the very beginning of the era of the primitive world, plants could not give people white bread, vegetable oil, and much more? (All plants were wild, people did not know how to care for plants).

    What are the names of plants grown by humans for food? (children's versions; cultural)

    How did wild plants become cultivated? (People eventually began to plant plants themselves and take care of them).

    You are right guys. People began to select, preserve and sow the best seeds, to pass on their experience from generation to generation. So man learned to breed varieties of cultivated plants. Many of them bear little or no resemblance to the wild ones from which they are descended. Thus, the science of crop production was born. How do you understand the meaning of this word? (children's guesses).

The entry opens on the board: PLANT.

A definition is given: crop production is the science of breeding cultivated agricultural plants.

GROUP WORKPE:

Before you photos: wheat, rye, cucumbers, zucchini, tomatoes, carrots, apples, pears, plums, cherries, roses, asters, lilies, gladioli, sunflowers, potatoes.

Divide the plants into 4 groups and try to name each group.

Checking the work of each group, followed by filling in the diagram on the board and individual diagrams.

Now let's take a look at each industry:

1. FIELD GROWING is the cultivation of field crops

Work with herbarium: rye, corn, barley, oats, millet and grains of these plants.

    Where are these plants grown? What are these cultures called? (These plants are grown in the fields, so these are field crops)

    How can each of these plants be distinguished from the others?

    The main field crops are cereals (wheat, rye, oats, barley, millet, corn, buckwheat). The fruits of these plants are called grains.

In each region, crop production has its own characteristics. It depends on natural

conditions.

Guys, try to explain what people do from the grain of these plants:

- from wheat (white bread, semolina);

- from rye (black bread; bran, straw - animal feed; straw hats);

- from oats (oat flakes);

- from barley (pearl barley);

- from millet (millet);

- from buckwheat (buckwheat);

- from corn (corn flakes, corn oil)

OTHER CROPS:

    sunflower (sunflower oil, seeds);

    potatoes - “second bread” (for food, in factories - starch);

    linen (linen fabric, linseed oil)

    Guys, what do you think, are all these field crops grown in our region? Why?Field farming.

    -Think about what this industry does? (growing field crops, the main ones are cereals)

    -Why is it called that? (these plants are grown in the fields, which means field plants)

    - What types of this industry do you know? (wheat, rye, barley ...)

    - Flour is obtained from rye and wheat and bread is baked. Semolina and pasta are obtained from wheat. Rye is higher than wheat. Its stem is taller than human growth. Rye and wheat grains differ in shape but are similar in color. Black bread is baked from rye grains. From rye, bran and straw are obtained, which are fed to domestic animals. And summer hats are woven from long straw stalks.

    Wheat is the most widespread cereal in the culture. Man began to cultivate wheat many thousands of years ago. In 8-7 millennia BC, wheat was grown on the territory of modern Iraq, Iran, Jordan and Turkey, as evidenced by archaeological finds. The first written evidence that ancient people grew wheat was found on cuneiform tablets of the inhabitants of an ancient state that existed in the 4th-3rd millennium BC between the Tigris and Euphrates. Now its crops occupy almost half of the world's arable land allocated for grain crops. And sow wheat literally everywhere.

    Wheat is spring and winter. Spring is sown in the spring, and after 3-4 months it is already harvested. Winter - in the fall, better in September (although the timing for our large country may be different). But it is impossible to be late with sowing. Plants should have time to spread, get stronger and harden before the onset of frost. However, you can't rush. Sow early and the plants will overgrow.

  • The most early-ripening, most winter-hardy and most drought-resistant wheats on the globe are soft wheats. They bake buns and pies. The quality of these products is improved by the addition of durum wheat flour. Pasta, vermicelli, semolina, so that they do not boil soft, are made from durum wheat flour.

    - What is obtained from millet and barley? (from barley - pearl barley, from millet - millet)

    -From oats, buckwheat? (Oat grains are oblong, they get oatmeal. Buckwheat has brown grains. It was brought from Greece, which is why it got its name. They get buckwheat).

    What is obtained from sunflower? (sunflower oil and seeds)

    - And from flax? (linseed oil)

    - This is a very interesting culture. Flax fiber is obtained from flax. In the old days, canvases were woven from this fiber and clothes were sewn.

    - And from potatoes? (for food - underground parts (tubers), they get starch)

    - Which of these cultivated plants are grown in our region? (wheat, rye, oats, potatoes, corn (does not ripen, goes for silage))

    -The cultivation of these plants is engaged in……………………… field cultivation

2. VEGETABLE - is the cultivation of vegetable crops

    Where are vegetables grown? (in the field, in the garden, in the greenhouse).

    Vegetable growers call a field and a vegetable garden an open ground, and greenhouses - a protected ground. Why do you think? Many vegetable farms have entire towns of greenhouses in which you can harvest all year round.

Heat-loving: tomatoes, peppers, cucumbers, zucchini

    What is the importance of vegetables? (nutrition - vitamins; contain phytoncides that kill pathogenic microbes - onions, garlic).

In individual schemes, write down the name of vegetable crops that are grown in our region in open ground (beets, carrots, cabbage).- Reading a poem

VI . Fizminutka.

    - The wind blows over the fields

    And the grass sways. (Children gently swing their arms over their heads.)

    The cloud floats above us

    Like a white mountain (Sipping - hands up.)

    The wind carries dust over the field.

    The ears are leaning

    Right-left, back-forward,

    And then vice versa. (Tilts right-left, forward-backward.)

    Mice hide in the rye.

    How to see them, tell me?

    A vole is hiding in a mink.

    Show yourself, you bastard!

    (Squats.)

    We're climbing the hill, (Walking in place.)

    And let's get some rest. (Children sit at their desks.)

VII . New material (continued)

3. FRUITS - growing plants to produce fruits

Demonstration of photos.

    In addition to apple trees, pears, peaches, ... garden raspberries, garden currants, garden strawberries, gooseberries belong to fruit crops.

    What is the importance of fruit crops? (useful, contain many vitamins)

NRK: What fruit crops are grown in our region? Fill in individual charts.

4.FLORITURE - growing flowers

Demonstration of photos.

    Where can flowers be grown? (in open ground - cold-resistant, in protected ground: in greenhouses, in greenhouses - heat-loving)

    What is the significance of this industry for a person? (for beauty) Show photos.

Guys, what do you think, which of the branches of crop production are the most developed in our country?

edge? Why?

    Guys, look at the photo and determine which plant you see? (pictured pepper tomatoes). Why were you wrong?

    The science of crop production does not stand still. Scientists are developing new varieties of plants. Demonstration of photos.

Currently in the world:

    onions - 1000 varieties;

    gooseberries - 1500 varieties;

    pears - 5000 varieties;

    apple trees - 10,000 varieties.

VIII . Reflection.

    Confirmation of the hypothesis put forward at the beginning of the lesson

    Guys, let's find out if the hypothesis we put forward at the beginning of the lesson was correct. Is it possible to do without plants? Why?

    Why does a person need knowledge about plant life?

2. GAME "GUESS". Name the plant and branch of crop production.

1) A child is wrapped in a hundred diapers (cabbage, vegetable growing).

2) Balls sit on the branches,

Turned blue from the heat (Plum, fruit growing)

3) Planted a seed, raised the sun (sunflower, field crops).

4) She has been proud of antiquity for ten thousand years,

Noisy in the fields under the blue sky

And feeds us all with white bread (wheat, field crops)

5) I won’t find such a flower in the field, it blooms on the bushes in the garden.

Write a short report about what you saw and did. You can draw or paste a photo. This spring, I helped my grandmother plant onions in her garden. It was very interesting. First we took a shovel and dug up the ground under the bed. Then we leveled the ground with a rake and formed a rectangular bed. Then the grandmother took a stick and drew straight longitudinal grooves on the bed. It was in these grooves that we began to plant small bulbs, which my grandmother called “onion sets”. Grandmother said that all the bulbs should be at an equal distance from each other. We deepened them a little into the ground and made sure that the root was always at the bottom, and the tail with a green seedling at the top. Then we sprinkled the planted bulbs with earth and watered them well from a watering can. I hope our bulbs will sprout quickly and we will eat them all winter.

crop production- the science of breeding cultivated agricultural plants, as well as such breeding itself. (“Explanatory Dictionary” by S.I. Ozhegov) Plants that a person himself plants, cares for seedlings, harvests, uses for food, are called cultural.

Crop growing is divided into several main branches: field cultivation, vegetable growing, fruit growing, floriculture.

field plants

A field is an open, treeless area in which cultivated plants are grown.

In the Perm Territory, grain crops are cultivated in the fields - rye, wheat, barley, oats, millet and buckwheat; vegetable crops - cabbage, carrots, beets, cucumbers, etc.; fodder crops - clover, vetch, peas, turnips, fodder beets, etc.; industrial crops - flax, potatoes.

Grain crops occupy the leading place in field crops. They are the basis for the development of other branches of agriculture and industry.

Among grain crops, the first place in terms of crops in the region is occupied by winter rye. It is cultivated in the north, in the central and southern regions. She is not afraid of cold weather, gives a good harvest and ripens early.

The second place in terms of crops of grain plants is occupied by wheat- the most valuable grain culture. She loves warmth, so she is cultivated in the southern part of the region.

Also grown in the northern regions barley and oats. In the south of the region - millet.

All these cultivated plants are different from each other, but in their structure there is much in common. All of them are herbaceous plants, the root is a bunch, the stem is a straw, hollow inside, has large nodes, which makes it strong and stable. Leaves are narrow and long. Small flowers of rye, wheat, barley are collected in ears, and millet and oats - in panicles. Later, fruits - grains - are formed from the flowers. Such plants are called cereals.

The grains of these plants are different from each other. For example, in rye, the grain is oblong, darker, in wheat - rounded, light.

Use of cultivated cereals

Plants from which bread is obtained are called bread plants.

Farmers have to spend a lot of time, effort, and money to grow crops, harvest crops and make bread. Therefore, it must be protected!

vegetable plants

Many vegetables are grown in the fields: cabbage, cucumbers, tomatoes, carrots, beets, radishes, radishes, onions, etc.

white cabbage often referred to as the "queen of vegetables".

When it becomes warm, seedlings are planted in fields and gardens. More and more leaves appear in plants. They hug each other tighter and tighter. This is how a head is formed. The inner sheets become juicy and white. There are 40 - 70 of them in a head of cabbage, and sometimes more, and they hold tightly, clinging to each other. Cabbage is harvested in autumn.

green cucumbers are a favorite vegetable plant. They are also good in winter pickled or salted.

spring seeds carrots, beets, radish sown directly on the beds and carefully watered. Small plants with green leaves appear. Their roots grow and become thicker and juicier. Nutrients accumulate in them: sugar, starch, vitamins. A month later, radishes ripen, and later - carrots and beets.

Plants that eat thickened roots are called root crops.

Onion- a valuable food product. It contains sugar and various vitamins. No meat or fish dish is complete without onions. Even in ancient times, onions were used as a healing plant for many diseases. Therefore, the people put together such a saying: "Onions from seven ailments." Our scientists have found that onions emit volatile substances (phytoncides), which kill putrefactive and pathogenic bacteria. Therefore, the use of onions in food has a healing value.

Onions eat green leaves and onions. Onions are native to dry steppes. The plant has adapted to store nutrients in the bulb during the dry period, which has wonderful properties. Many people store onions in the winter, and they do not dry out. In spring, the bulb sprouts easily and produces green leaves, and in greenhouses even in winter. She can easily winter. Sometimes they plant lek on the beds before winter. When the snow begins to melt, green leaves will already appear on the onion.

Potato- a valuable food product. It is often referred to as "second bread". Potato is an important industrial crop. Starch, alcohol, molasses are obtained from it.

In the underground part of the potato stalks produce underground white branches, at the ends of which thickenings are formed - young tubers. They gradually increase and fill with starch. In autumn, a rich crop of potato tubers is usually harvested.

fruit and berry plants

Due to cold and long winters, horticulture in the Perm region is underdeveloped. But still, gardeners grow sea buckthorn, cherries, garden strawberries, currants, raspberries, gooseberries, plums, apple trees, etc.

Horticulture is concentrated in the south of the region and in the suburbs of Perm, Chusovoy, Krasnokamsk, Okhansk and other settlements. But still, most of the fruits for the population are brought from other countries and the southern regions of our country.

Floriculture

From year to year, our cities and towns are decorated with flowers in the spring and summer. In the spring, when the snow just melts, the first perennials appear on the garden plots: snow-white narcissus s with an unforgettable delicate aroma, red and yellow tulips, purple irises.

later bloom peonies. They delight with the richness of colors and the size of a saucer of flowers: scarlet, pale pink, white with a pleasant smell.

Then red and white appear carnations, lilies. Bloom tall and slender phloxes: lilac, purple, pink and white. They bloom all summer.

carnation lily phlox

In the second half of summer, beautiful dahlias of various colors and shapes bloom and are surprisingly elegant. gladioli.

In squares, parks and on the streets, mostly annuals bloom: asters, cosmos, petunias, marigold, calendula and many others.

Calendula Asters Kosmeya Marigolds

In the city of Perm there is an enterprise "Flowers of Prikamye", where plants bloom in greenhouses all year round, including beautiful roses.

Seedlings of annuals are grown here for landscaping and decorating the city.

The power of the impact of colors on people's feelings is enormous. They heal us, inspire us and improve our mood. They decorate homes, streets, parks and gardens. They are handed over at solemn events, presented for holidays, laid on the graves of the dead, at the obelisks. On Victory Day, May 9, they are presented to war veterans.

Spring work begins with the cultivation of the land. These works are most often performed using special equipment. This is followed by sowing seeds and planting cultivated plants. There is a small flower garden near our house. There, with my mother, we plant flower crops. We planted some of them in the ground with seeds, others with seedlings. Then we will regularly water the flowers and weed them.
