Control method of crop freezing injury

Abstract

The invention discloses a control method of a crop freezing injury. The method comprises the steps that a leaf surface plant anti-freezing solution is prepared, wherein the leaf surface plant anti-freezing solution is composed of, by weight, 15-18 parts of glycerinum and 5-8 parts of edible gum; a rhizome plant anti-freezing solution is prepared, wherein the rhizome plant anti-freezing solution iscomposed of, by weight, 15-18 parts of glycerinum, 5-8 parts of edible gum, 13-15 parts of glucose and 1-4 parts of cotton fiber, the length of the cotton fiber is 100-150 micrometers, and the diameter of the cotton fiber is 20-50 micrometers; the leaf surface plant anti-freezing solution is sprayed; the rhizome plant anti-freezing solution is sprayed; the leaf surface plant anti-freezing solution is sprayed again; plant straw particles are evenly spread on the ground around a plant; plant straw particles are strapped around the lower portion of the stem of the plant to form a heat-preservingsleeve, the leaf surface plant anti-freezing solution is taken, water is added into the leaf surface plant anti-freezing solution for 50-time dilution, and then the diluted leaf surface plant anti-freezing solution is poured onto the roots of the plant. By means of the method, the leaves, the buds and the stem of the plant can be effectively prevented from being subjected to the freezing injury,and the cold resistance of the plant is enhanced.

Description

technical field [0001] The invention relates to a method for preventing and treating freezing damage of crops. Background technique [0002] In northern my country, the temperature often changes in early spring, late autumn and early winter, and crops are often invaded by cold waves due to sudden changes in the weather. The sharp drop in temperature caused severe freezing damage, which caused the loss of some tissues such as leaves and flowers. Even for some cold-resistant crops, the cold-resistant exercise in the crops had not been completed at the end of autumn, resulting in huge losses. [0003] The impact of freezing damage on crops is mainly caused by the freezing of plant cell spaces and plant cell freezing. When the temperature drops rapidly, the water in the cell spaces first freezes, and the water vapor in the surrounding cells flows into the ice crystals in the cell spaces. Coagulation increases the volume of ice crystals and causes mechanical damage to the cell p...
