How to protect plants from spring and summer frosts
In many regions of our country at the end of may and even in June, night frosts happen return.
They can cause damage to the future harvest of fruit and berry crops.
Usually recurrent frosts occur when the temperature drops below 0° during the night.
The most dangerous frosts are older, who meet in early June. This period is the most active in the development of cultures.
The temperature, which causes the death of the generative organs of plants or partial damage of the vegetative mass, for different crops and even different varieties unequally. The degree of damage depends on the phase of plant development.
Even in one suburban area temperature in the surface layer may vary depending on the location of the backyard and garden.
For example, in low-lying areas, the risk of late frosts increases dramatically. This is due to the fact that warm air is lighter than cold, so it rises, giving way to low cold flow.
The resistance of plants to late spring frosts, can improve macro — and micronutrients. They play a significant role in the development of cultures.
Phosphorus increases winter hardiness of plants, potassium and copper boost immunity to disease, frost and drought.
An important role in the life of plants is played by the water. It is an indispensable participant in metabolic processes. The optimal water regime enhances the natural immunity of plants and increases resistance to frost.
By their appearance quite simple to notice the impact of frost on the culture. Plants appear dark spots, while damaged not only the outer part of the flower, but the ovary.
The defeat leaves perennial crops is considered less dangerous because they are able to give new growth from dormant buds.
Protecting plants from spring frosts
The oldest known method of protecting plants against cold – smoke. The main condition of this method: the smoke must travel along the surface of the earth. The smoke is carried out in calm weather.
As the glow material well-suited sawdust, leaves, straw. They can smoke without any open manifestation of fire.
Also to protect plants from spring frosts use of non-woven material, it holds heat well. Unfortunately, it is not suitable for the protection of trees. The denser the material, the better heat stored beneath it.
Irrigation is another way to protect plants from spring and summer frost. It
the easiest way and quite effective.
The wet ground creates a specific microclimate around the crops. Day soil accumulates heat from the sun, and at night gradually gives.
The plants watered before the frost. Prolonged decline in night temperature, carry out additional watering.
