Chitosan-containing and heat-insulating nutritional plant anti-freezing agent and preparation method thereof

Abstract

The invention discloses a chitosan-containing and heat-insulating nutritional plant anti-freezing agent and a preparation method thereof. The chitosan-containing and heat-insulating nutritional plant anti-freezing agent is characterized by being prepared from the following raw materials in parts by weight: 1 to 3 parts of chitosan, 6 to 12 parts of polylactic acid, 2 to 3 parts of chlormequat chloride, 3 to 6 parts of dehydrated sorbitan fatty acid ester, 9 to 16 parts of chloroform, 25 to 35 parts of water, 5 to 10 parts of a corn protein powder, 1 to 2 parts of yeast colonies, 1 to 3 parts of glucose, 2 to 4 parts of amino acid, 4 to 6 parts of glycerinum, 1 to 2 parts of sodium dodecyl sulphate, 2 to 5 parts of magnesium chloride and 2 to 5 parts of urea. According to the chitosan-containing heat-insulating nutritional plant anti-freezing agent and the preparation method thereof, the corn protein powder is soaked in the glucose and the amino acid and adhered to a plant body through an adhering effect of the polylactic acid, so that a heat insulating effect can be achieved, wherein the sugar content and the content of free amino acids in the plant body can be increased remarkably by the glucose and the amino acid; an effect on protecting cells is achieved; influences on a plant caused by freezing damage are effectively reduced; the chitosan and the like are matched and added to enhance an anti-freezing effect of the plant.

Description

technical field [0001] The invention relates to a plant antifreeze agent, in particular to a chitosan-containing, heat-preserving and nutritious plant antifreeze agent and a preparation method thereof. Background technique [0002] During the wintering period, when the temperature is below 0°C, the plants often suffer from cell injury or death. At present, one of the main antifreeze measures for plants is to spray antifreeze. Antifreeze is also called antifreeze. It can significantly improve the antifreeze ability of green plants, various fruit trees and seedlings in disease resistance, low temperature and late spring cold when applied to various plants. , Effectively prevent morning and evening frost attacks, avoid or reduce frost damage. There are many types of chemical antifreeze products on the market, but the principles of antifreeze can be roughly divided into three categories. One is the type of inducer, which uses growth hormones to induce the production of antifree...
