Problems solved by technology

Salt always exists in the form of ions in the soil. When plant roots absorb water, the salt ions dissolved in water are also absorbed and enter the plant in large quantities, so that the leaves contain a large amount of Na + and Cl - , and sorghum is sensitive to salt, and cannot effectively gather the salt ions absorbed into the cells into the vacuoles. The accumulation of a large amount of salt in the cells will cause the coagulation of protoplasm and the destruction of photosynthetic pigments, which seriously affects the growth of sorghum.
[0003] The traditional sorghum seed coating agents widely used at present are basically pesticide-type reagents, containing toxic fungicides, such as Shilax, carbofuran and thiram, although they can effectively reduce the number of fungi and improve seed quality, but these fungicides are in the soil. It will cause toxic accumulation and seriously damage the ecological environment
In addition, traditional seed coating agents are not salt-tolerant, and cannot promote the growth of sorghum in areas with soil salinization

Abstract

The invention relates to an environment-friendly salt resistant sorghum seed coating and a preparation method thereof. The sorghum seed coating is neutral emulsion containing chitosan solution, aminoacid, nutrient element composition, emulsifier, plant growth regulator and warning coloration, wherein the mass percent content of the chitosan solution is 56 to 60 percent and the mass percent content of the amino acid solution is 6 to 9 percent. The sorghum seed coating provided by the invention has functions of salt resistance, bacteriostasis and yield increase, can promote the growth of the sorghum in the salinized soil environment such as northeast, northwest, North China and coastal regions, can avoid insect pest through bacteriostasis rather than sterilization, has obvious protection effect on biologic chain and no harmful pesticide composition, can be degraded, has no pollution on environment and has obvious environmental benefit.

Description

technical field [0001] The invention relates to the technical field of seed coating agents, in particular to an environment-friendly salt-tolerant sorghum seed coating agent and a preparation method thereof. Background technique [0002] Sorghum is one of the important dryland grain crops in my country, and it is an important raw material for industrial production and livestock feed. At the same time, it is also an important raw material for brewing famous liquor, and its role cannot be replaced by other crops. However, sorghum is vulnerable to various pathogens during seed germination and plant growth, such as smut, Cercospora sorghum, and Anthracnose graminearum, which seriously affect the yield and quality of sorghum. In addition, in the arid and semi-arid areas of Northeast, Northwest, and North China, the precipitation is small and the evaporation is large, so the salt dissolved in water tends to accumulate on the soil surface, which forms soil salinization. Salt alway...
