Trunk protection liquid

Abstract

The invention provides a trunk protection liquid which comprises the following components by weight: 2-5 parts of paraffin, 5-8 parts of vegetable oil, 4-8 parts of isobutene, 3-9 parts of BFA, 5-9 parts of acetic acid, 2-6 parts of tea polyphenol, 2-5 parts of citric acid, and 2-5 parts of cooking liquid of acacia catechu, bletilla, dried chilli and tangerine peels, wherein the content of ions Cu+Fe+Mn+Zn+B in an antifreezing agent is not less than 105 g/L. The trunk protection liquid is simple in proportion, and convenient to use, can reduce the freezing injury loss of trees greatly, is good in anti-freezing effect, activates biological enzymes, prevents the ice nucleating bacteria from generation, destroys the frozen protein ice formation activity, increases heat quantity, reduces the plant cell freezing point value, promotes the flowing of cellular plasm, improves the cell viability by 4-8 times, increases the water retaining and drought capability of the plants, reduces the freezing injury, alleviates the rehabilitation effect on medium-low-grade freezing injured plants, has no effect on the high-grade injury, and reduces the plant freezing point value by 5-8 degrees.

Description

[0001] Technical field: [0002] The invention relates to the technical field of forest protection, in particular to a tree trunk protection liquid. [0003] Background technique: [0004] In northern China, the severe cold, dry and windy winter will cause some less cold-tolerant tree species to suffer freezing damage or cause "physiological drought" (also called freezing drought, cold drought or winter drought) from winter to early spring, causing local branches to wither. From the damage to some branches, the whole plant will die. In order for trees to survive the winter safely, it is necessary to understand the causes of low temperature hazards and take necessary measures. For example, root frost damage is due to the lack of natural dormancy in the root system and poor frost resistance. Roots close to the ground are susceptible to freezing damage, especially in sandy land with little snow and aridity in winter. The root system is frozen and it is often difficult to find in ti...

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 disas
