No matter how seemingly different plants from each other, they all share the need for light, heat and water.In the absence of even one of these factors, the life of any organism green decelerates or stops altogether.
What is missing plants in the middle band
The illumination is a very important prerequisite for optimal plant growth.Without adequate light quantity is reduced photosynthetic activity.
short summer, which is typical for the middle band region, and a large number of overcast days often lead to a reduction in the formation of chlorophyll, resulting in plant leaves are paler, decreasing their area, and the stems are drawn.
Even for frost-resistant species growing in the northern regions, the heat - this is what is missing plants.In central Russia sprouts easily tolerate freezing, but at low temperatures, all vital processes in their bodies freeze.
Without water there can be no plant.Some of them spend all their life in the water, while others grow on land, but requires a lot of water.There are those who absolutely do not need a lot of moisture.But no water plant life impossible.Lack of it may be due to the number of very dry summer, when enough rain falls.At such times, the life expectancy will depend on how the plant enough power.Central strip climatic conditions more severe than the south, so the plant world offers much greater endurance.
Features herbaceous plants in the middle band
in conditions of seasonal climate, common in Russia, many plants acquire some features.Perennial herbs are runaways, crawling on the surface or underground, which can exist for many years.The aerial parts of these plants live one year, after which they die completely.
Annuals are one season their entire life cycle.Growing from seeds they bloom, bear fruit and die.What is missing in the middle zone of the plants particularly since it is a long warm season with plenty of sunshine.
Creating the necessary conditions
Man is able to create the conditions for plant life, where they can survive and grow well.As the scientists, the most dangerous plant sharp drop in temperature, causing the water in the stem turns into ice, and the plant dies.As a result of hard work were new varieties of fruit trees that are able to tolerate frosts even to minus 60⁰S.It is believed that not enough plants in the middle zone of heat to a greater extent.Therefore, scientists are working on breeding frost-resistant varieties.
often practiced together planting several different crops.In this case, one of them serves as support for the other.When planting corn near the pumpkin it protects the latter from direct sunlight.A pumpkin, in turn, closes its ground leaves, thus maintaining moisture.
studying the question of what is missing plants in central Russia, specialists use a variety of modern methods of promoting the cultivation of high yields of fruit and vegetable crops, even with a deficit of heat and light.
