Spraying fluid capable of preventing trunk from freezing and bursting

Abstract

The invention provides a spraying fluid capable of preventing a trunk from freezing and bursting. The spraying fluid is prepared from, by weight, 2-5 parts of ethylene glycol, 5-8 parts of methyl ester, 4-8 parts of isobutene, 3-9 parts of potassum fulvic acid, 5-9 parts of calcium chloride, 2-6 parts of tea polyphenol, 2-5 parts of citric acid and 2-5 parts of alcohol leaching liquor of rhizoma ligustici, indigowoad leaves, fistular onion stalks and cinnamon. The content of ions Cu+Fe+Mn+Zn+B in an antifreezing agent is larger than or equal to 105 g / L. The spraying fluid capable of preventing the trunk from freezing and bursting is easy to match, convenient to use, capable of greatly reducing frost damage of trees and good in anti-freezing effect; the spraying fluid activates biological enzymes, prevents ice nucleating bacteria from generating, destroys ice-forming activity of frozen protein and increases heat. Freezing point values of plant cells are reduced, flow of cellular plasm is promoted, and the cell viability is increased by 4-8 times. Water retention and drought resistance capacities of the plants are increased, frost damage is decreased, reducing and rehabilitating effects on middle-light freezing plants are achieved, the spraying fluid is invalid for sever damage, and the freezing point values of the plants are decreased by 5-8 degrees.

Description

Technical field: [0001] The invention relates to the technical field of forest protection, in particular to a spray liquid for preventing tree trunks from freezing and cracking. 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 suscep...

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.
