Anti-freezing agent for trees

Abstract

The invention provides an anti-freezing agent for trees. The anti-freezing agent comprises, by weight, 2-5 parts of paraffin, 5-8 parts of plant oil, 4-8 parts of polybutylene, 3-9 parts of fulvic acid, 5-9 parts of salicylic acid, 2-6 parts of tea polyphenol, 2-5 parts of glacial acetic acid and 2-5 parts of cooking liquor of folium artemisia argyi, roots of kudzu vine, ginger and mirabilite. The ion content in the anti-freezing agent is that Cu+Fe+Mn+Zn+B>=100 g / L. The anti-freezing agent is easy to prepare, convenient to use, capable of lowering freezing loss of the trees substantially, and good in anti-freezing effect; the anti-freezing agent can activate a biological enzyme, prevent ice nucleus bacteria from being generated, damage the icing activity of frozen protein and increase heat, thereby lowering the freezing point value of plant cells, promoting flow of cellular protoplasm, and increasing the cell viability by 4-8 times; besides, the anti-freezing agent enhances the water retention and drought resistance ability of plants, relieves freeze injuries, plays a role in relieving the freezing injuries of the plants frozen to a moderate or light degree and recovering the plants, is ineffective on severe injuries, and lowers the freezing point value of the plants by 5-8 degrees.

Description

[0001] Technical field: [0002] The invention relates to the technical field of tree protection, in particular to a tree antifreeze agent. [0003] Background technique: [0004] 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 freeze 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 sys...

Problems solved by technology

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, the labor intensity is high, and it needs to be disassembled again next spring, resulting in a serious waste of resources. In view of this technical problem, it is necessary to have a simple proportioning, easy to use, which can greatly reduce the loss of tree frost damage and antifreeze effect. good tree antifreeze
