Use method of tree anti-freezing spraying agent

Abstract

The invention provides a use method of a tree anti-freezing spraying agent. The use method includes the use steps of A, diluting the tree anti-freezing spraying agent into 800-volume-fold liquid through water to be sprayed in late autumn and before plant dormancy; B, diluting the tree anti-freezing spraying agent into 600-volume-fold liquid through water to irrigate roots 3-7 days before frosting or cold waves; C, diluting the tree anti-freezing spraying agent into 1000-volume-fold liquid through water to irrigate the roots before and after plant transplanting; D, diluting the tree anti-freezing spraying agent through water by 50-80 volume folds to conduct trunk and branch brushing operation before winter. The steps are required to be conducted at the temperature between 3 DEG C and 8 DEG C. The tree anti-freezing spraying agent comprises 1-hydroxy ethylidene-1,1-diphosphonic acid, tolyl triazole sodium, polybutylene, fulvic acid potassium, benzoic acid, tea polyphenol, phosphoric acid triethanolamine, Chinese mosla herbs, ginger, chrysanthemum and burdock. The use method is simple in ratio, convenient to use, capable of greatly reducing cold injury loss of trees and good in anti-freezing effect.

Description

Technical field: [0001] The invention relates to the technical field of forest protection, in particular to a method for using an antifreeze spraying agent for trees. Background technique: [0002] Frost damage to trees: One is the winter sunburn on the sunny side (especially southwest). Due to the large temperature difference between day and night during early winter and early spring, the skin tissues move with the increase in the sun's temperature, and the night temperature drops sharply and freezes. The second is freeze cracking (also known as longitudinal cracking, cracking and drying). Due to the sudden drop in temperature in early winter, the cortex tissue rapidly shrinks, and the xylem produces stress and stretches the bark; the intercellular icing can also cause cracks. Freezing injury of branches mainly occurs on the inward side of the branches. Symptoms are discoloration of the cortex, depression of necrosis, or vertical split along the main trunk. The duct rupture...

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 in the next spring, resulting in a serious waste of resources. In view of this technical problem, there is a need for a simple proportioning, easy to use, which can greatly reduce the loss of trees due to frost damage, and has an antifreeze effect. A good method of using tree antifreeze spray agent
