Antifreezing agent

Abstract

The invention provides an antifreezing agent, wherein the antifreezing agent comprises the following components in parts by weight: 2-5 parts of paraffin, 5-8 parts of vegetable oil, 4-8 parts of glycerinum, 3-9 parts of acetic 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 a cooking liquor of bamboo leaves, ochre, Chinese mosla herb and pine needles. The antifreezing agent is simple in ratio and convenient to use, greatly reduces the loss caused by the freeze injury of a tree, and has an excellent antifreezing effect. The antifreezing agent activates the biological enzyme, stops the production of ice nucleating bacteria, breaks the icing activity of frozen protein, increases the heat, reduces the freezing point of a vegetable cell, promotes the flow of the cellular plasm, and improves the cell viability by 4-8 times. The water-retaining and drought-resisting abilities of the plant are improved, the freeze injury is alleviated, the antifreezing agent has an effect of alleviating and recovering the moderate and mild freeze injury plants, has no effect on the severe injury, and reduces the freezing point of the plant by 5-8 DEG C.

Description

[0001] Technical field: [0002] The invention relates to the technical field of forest protection, in particular to an antifreezing agent. [0003] Background technique: [0004] The frost damage of crops, such as tree freeze damage, mainly occurs on the inward side of the branch. Symptoms are cortical discoloration, necrotic depression, or vertical cracking along the main trunk. Due to the narrow annual rings at the branches, underdeveloped ducts, poor support, low nutrient accumulation, poor cold resistance and other reasons, the ducts rupture, resulting in gum flow in the next spring. At the same time, because snow is easy to accumulate at the branches, the bark will be soaked to make the tissue soft after the snow melts, and it will be damaged if the temperature drops suddenly. [0005] In the traditional prevention and control of tree frost damage, lime and lime sulfur are used to whiten the branches and trunks, which can reduce the damage to the sunny skin due to t...

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 antifreeze
