What do the plants in the middle strip lack? Features of the plants of the middle band

No matter how different the plants differ from each otherfriend, they all are united by the need for light, warmth and water. In the absence of even one of these factors, the vital activity of any green organism is inhibited or stopped altogether.

What the plants in the middle band lack

Illumination is a very important condition for optimal plant growth. Without sufficient light, photosynthetic activity decreases.

Short summer, which is typical for the regionsand a large number of cloudy days often lead to a reduction in the formation of chlorophyll, resulting in the leaves of the plants become paler, their area decreases, and the stems stretch.

Even for frost-resistant species growing innorthern regions, warmth is what the plants lack. In the central part of Russia, shoots can easily tolerate frosts, but at low temperatures all life processes in their bodies freeze.

Without water, no plant can exist. Some of them spend their whole lives in the water, others grow on land, but water requires a lot. There are also those who do not need a lot of moisture at all. But the life of a plant is impossible without water at all. Insufficient amount of it can be the result of a too dry summer, when there is not enough precipitation. In such periods, life expectancy will depend on how much power the plant has. The middle belt climatic conditions are somewhat more severe than the southern one, so the plant world is much more enduring.

Features of herbaceous plants in the middle band

In a seasonal climate, typicalmiddle belt of Russia, many plants acquire certain features. Perennial herbs have shoots creeping over the surface or under the ground, which can exist for many years. The aerial parts of these plants live one year, after which they die completely.

Annuals of plants pass in one season allits life cycle. Growing from seeds, they bloom, bear fruit and die. What is missing is the plants in the middle band especially, so this is a long warm season with enough sunny days.

Creating the necessary conditions

Man is able to create such conditions for lifeplants, when they can perfectly survive and develop. As scientists have established, the sharpest drop in air temperature is most dangerous for plants, as a result of which the water in the stalk turns into ice, and the plant dies. As a result of painstaking work, new varieties of fruit trees were introduced, which are able to tolerate frost even up to minus 60 ° C. It is believed that not enough plants in the middle band are more warm. Therefore, scientists are working on the breeding of frost-resistant varieties.

Often practiced joint plantingseveral different cultures. In this case, one of them serves as a support for the other. When planting corn next to the pumpkin, it protects the latter from direct sunlight. And the pumpkin, in turn, closes the soil with its leaves, thus keeping moisture.

Studying the question of what the plants lack inmiddle zone of Russia, experts apply a variety of modern methods that promote the cultivation of high yields of fruit and garden crops, even with a shortage of heat and light.
