Problems solved by technology

[0003] The traditional soybean seed coating agents widely used at present are basically pesticide-type reagents, containing toxic fungicides such as Shilax, Docfur and thiram. Although the use of traditional methods can effectively reduce the number of fungi and improve seed quality, these fungicides It will cause toxic accumulation in the soil and seriously damage the ecological environment
In addition, pathogenic bacteria may develop resistance to fungicides, which means increasing the amount of fungicides used to achieve the antibacterial effect

Abstract

The invention relates to an environment-friendly soybean seed coating agent and a preparation method thereof. The environment-friendly soybean seed coating agent is prepared from the raw materials ofa chitosan solution and a biological bacteriostatic agent emulsion; the chitosan solution is obtained by dissolving chitosan in an acetic acid solution; the biological bacteriostatic agent is one or more of sucrose stearate monoester, sucrose palmitate monoester and sucrose oleic acid monoester; the mass ratio of the chitosan solution to the biological bacteriostatic agent emulsion is (45 to 50) to (2 to 5). The environment-friendly soybean seed coating agent provided by the invention contains no harmful pesticide ingredient, is degradable, has no environmental pollution, and is low in cost and good in bacteriostatic and deworming effects; furthermore, the insect pests are avoided through expelling parasites rather than killing the parasites, an obvious protective effect is realized on thebiologic chain; in addition, the environment-friendly soybean seed coating agent has an obvious yield-increase effect on soybeans.

Description

technical field [0001] The invention belongs to the technical field of seed coating agents, and relates to an environment-friendly soybean seed coating agent and a preparation method thereof. Background technique [0002] Soybean is one of the important food crops in China, and its seeds are rich in plant protein. Soybeans are most commonly used to make various soy products, extract soybean oil, brew soy sauce and extract protein. However, soybeans are vulnerable to various pathogens such as soybean gray mold, soybean bacterial spot, soybean downy mildew, damping-off, blight, and purple spot during the seed germination stage and plant growth. At the same time, pests such as Lygus clover bug, soybean aphid, beetle chinensis, bean leaf butterfly and soybean borer also have a serious impact on the quality of soybean. Pests and diseases caused the number of pods of the affected plants to decrease, the 100-kernel weight to decrease, and the number of brown spots to increase. Y...
