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.

Andrienko N.V.

2015

Subject : PLANT PRODUCTION IN OUR REGION

The objectives of the lesson: to form students' ideas about crop production in our region, to introduce the branches of crop production, to expand knowledge about plants, to develop cognitive interest, the ability to observe and use their observations in practical activities; to cultivate a careful attitude to bread, the work of parents.

Equipment:Gherbarium of field crops, vegetables, fruits, cereals, illustrations

plants, software, presentation.

During the classes

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.

Musk rat I

My whole family is in the hole.

The mink itself is on the mountain,

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 allotted 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.

VARIETIES OF CULTIVATED PLANTS

Roses of different varieties

Once upon a time there were no cultivated plants on Earth. There were only wild ones.

A man began to grow some of them near his home. People selected, preserved, propagated the best of these plants. Thus, cultivated plants gradually arose - they acquired the properties necessary for man.

Man has bred a variety of varieties of cultivated plants. Many of them bear little resemblance to the wild plants from which they originated. Breeding of new varieties continues.

Now in the world there are only about 1,000 varieties of onion, 1,500 gooseberries, 2,000 plums, 5,000 pears, and at least 10,000 varieties of apple trees!

PLANT INDUSTRIES

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

In each region, crop production has its own characteristics, which depend on the natural conditions of the region.

Comprehension and understanding of the acquired knowledge

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. Present the results of your work to the class. With the whole class, summarize the information about crop production in your area.

field farming

Practical work

Consider field crops in your area in the herbarium. Determine their names with the help of a picture. Compare them to each other. By what signs can these plants be distinguished?

2. Learn to distinguish grains of wheat, rye, oats and other grains

field farming is the cultivation field crops. The main field crops are cereals. These include wheat, rye, oats, barley, pro-so, corn, buckwheat.

White bread is baked from wheat flour, black bread from rye flour. Oatmeal is made from oats. Barley gives pearl barley, millet - millet groats (millet), buckwheat - buckwheat groats.

Corn for grain is grown in the southern regions (it is a heat-loving crop). In the more northerly regions, corn grain does not ripen, so here silage is obtained from it.

Other field crops - potatoes, sunflower, flax.

You know that people use potato tubers for food. They also go to feed pets. And in factories, starch is obtained from potato tubers. From sunflower seeds, sunflower oil is obtained, and from flax, flax fiber for making fabrics.

vegetable growing

Vegetable farming is the cultivation vegetable crops. There are many of them: cabbage, carrots, tomatoes, cucumbers, onions ... Continue this list orally.

Grow vegetables in the field, in the garden, in greenhouses. Vegetable growers call the field and vegetable garden open ground, greenhouses - protected ground. Many vegetable farms have entire towns of greenhouses in which you can harvest all year round.

Vegetables play a very important role in human nutrition. They are rich in vitamins, various salts and other healthy substances. Some vegetables - onions, garlic - contain phytoncides.

fruit growing

Horticulture is the cultivation of fruit crops. So it is customary to call plants that are grown to produce fruits. The most common in our country are apple, pear, cherry, plum, currant, strawberry, raspberry, gooseberry.

You know well that fruits are very beneficial for human health. In addition, they are also very tasty!

Floriculture

Floriculture is cultivation flower crops. They are grown to decorate parks, squares, gardens, various premises, to obtain cut flowers. Some plants are grown in open ground, others - in greenhouses, greenhouses, rooms.

People began to engage in floriculture in deep antiquity. Interestingly, peonies, lilies, irises, and tulips were already grown in the garden of the Moscow Kremlin in the 16th-17th centuries. And in the 18th century, in 1704, a wonderful garden with beautiful flower beds was created in St. Petersburg - the Summer Garden. It is still a decoration of the city.

The world of flowers is amazingly diverse. And all of them delight people with their beauty, make a person's life happier.

Pages for the curious

Who helps to save the harvest

Scientists have done this. They fenced off the area with 70 larvae of the Colorado potato beetle in a potato field. They let in 5 predatory ground beetles. A few days later all the larvae were eaten by ground beetles...

A ladybug crawls on the leaves of an apple tree. What is she looking for here? Of course, aphids. During her life, she eats about four thousand of them. Ladybug larva is also a predator. She eats about a thousand aphids in her life.

Very beautiful lacewings! Light, delicate, with lacy bluish-green wings, they look like small dragonflies. And their eyes, like golden beads, sparkle in the sun. The larvae of lacewings have huge jaws compared to their bodies. With the help of these jaws, the larvae eat aphids.

In the next lesson

We learn about the work of livestock breeders in our region. We will learn to distinguish between branches of animal husbandry, to correlate breeds of domestic animals with them.

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?
