Anti-freezing agent for crops

Abstract

The invention discloses an anti-freezing agent for crops. The anti-freezing agent comprises, by weight, 11-17 parts of polyethylene glycol, 10-15 parts of water-soluble chitosan, 3-6 parts of nanometer waterborne adhesive, 5-8 parts of dendritic macromolecular substances, 1-3 parts of soybean hydrolyzed amino acid, 1-3 parts of amino acid chelated calcium, 1-3 parts of potassium dihydrogen phosphate, 0.01-0.03 part of indoleacetic acid, 0.2-0.4 part of brassin, 0.02-0.04 part of emulsion dispersed polyethylene wax, 0.01-0.03 part of abscisic acid, 3-6 parts of garlic oil, 70-80 parts of polycarbonate, 10-20 parts of acrylonitrile-butadiene-styrene copolymers, 1-10 parts of inorganic nanometer particles, 0.5-10 parts of acrylonitrile-styrene copolymers and 3.5-10.5 parts of chemical-resistant modifiers. The anti-freezing agent has the advantages that the anti-freezing agent is convenient to use, freezing injury loss of trees can be reduced to a great extent, and good anti-freezing effects can be realized.

Description

technical field [0001] The invention relates to the field of ammonia nitrogen detection, in particular to an antifreeze agent for crops. Background technique [0002] In northern China, severe cold, dry and windy winter will cause some less cold-resistant tree species to suffer from freezing damage or cause "physiological drought" (also called freezing drought, cold drought or winter drought) in winter to early spring, causing local branches to wither. In some cases, some branches will be damaged, and in severe cases, the whole plant will die. In order for trees to survive the winter safely, it is necessary to understand the causes of low temperature damage and take necessary measures. For example, root freezing damage has poor frost resistance because the root system has no natural dormancy. Roots close to the surface are susceptible to freezing damage, especially in dry sandy land with little snow in winter, and are more susceptible to freezing. The root system is froze...

However, this method is not suitable for colder areas. In colder areas, most of them use tree trunks to wrap straw curtains, and then wrap plastic cloth outside the straw curtains to prevent freezing.

The operation is cumbersome and labor-intensive, and it needs to be disassembled in the next spring, resulting in a serious waste of resources
