A kind of antifreeze agent for fruit trees and its preparation and use method

Abstract

The invention discloses an antifreeze agent for fruit trees and its preparation and use method. It consists of the following raw materials in parts by weight: 1.50-3 parts of sucrose fatty acid ester, 2-5 parts of calcium acetate, 5-10 parts of glycerin, and 2-3 parts of potassium dihydrogen phosphate. 7 parts, 0.1-0.5 parts of plant growth regulator, 2-5 parts of nutrients, and add water to 100 parts. Compared with the prior art, the antifreeze agent for fruit trees involved in the present invention has simple preparation method, low cost, easy long-term storage, non-toxic and harmless, easy biodegradation, no edible chemical residue and no environmental pollution. And it can reduce the occurrence of fruit tree diseases, especially in the wounds caused by fruit tree pruning to form a protective film to prevent the invasion of external diseases. The addition of the spreading agent can reduce the surface tension of the antifreeze, increase the wetting and spreading of the antifreeze on the leaf surface, improve the adhesion ability of the antifreeze, increase the effective period of antifreeze, and the method of use is simple, and it is easy to use in large-scale agricultural operations.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to an antifreeze agent for fruit trees and its preparation and use method Background technique [0002] Plant winterization has definite needs in both agriculture and forestry. Especially in recent years, the temperature in winter is low, and the late spring cold frequently occurs, which seriously affects the development of agriculture and forestry, especially in agriculture, which has a great impact on fruit farmers. Plant antifreeze can significantly improve the antifreeze ability of plants including fruit trees and forest trees, effectively avoid or reduce the damage to plants caused by late spring cold, morning and evening frost, etc., promote the rapid recovery of frostbitten plants, and avoid greater damage to my country's agriculture and forestry. Harm, to avoid fruit yield decline and economic loss. [0003] At present, the main means for plants to prevent cold and frost is physi...

AI Technical Summary

Problems solved by technology

It effectively solves the food safety and environmental safety of fruits, and solves the problems of high cost, complicated process, and short storage period, making the antifreeze solution easier to be accepted by the agricultural market, so as to reduce the impact of freezing damage on fruit production and reduce economic losses
