Coating agent for high oil content crop seeds

Abstract

The invention discloses a coating agent for high oil content crop seeds and relates to the technical field of seed treatment. The coating agent comprises, by weight parts, 25-30 parts of butyl methacrylate, 10-15 parts of methyl acrylate, 6-11 parts of styrene, 5-9 parts of pentaerythritol oleate, 4-7 parts of hydrogenated rosin, 4-7 parts of methacrylamide, 4-7 parts of carnauba wax, 3-6 parts of polyvinylpyrrolidone, 3-6 parts of sodium carboxymethyl starch, 2-4 parts of polyglycerol polyricinoleate, 2-4 parts of moisture absorption cooling agent, 2-4 parts of microcrystalline wax, 1-2 parts of octadecanamide, 1-2 parts of polymaleic anhydride, 1-2 parts of polyquaternary salt, 0.5-1 part of asbestos powder, 0.5-1 part of mirabilite, 0.5-1 part of ammonium persulfate and 80-100 parts of water. On one hand, the coating agent can prevent the influence of the external environment on the seeds by utilizing its own isolation effect, on the other hand, the coating agent can adsorb redundant moisture and heat through adsorbing and insect-killing bactericidal ingredients and perform mothproof and mold-proof prevention on the seeds, so that the seed storage quality is effectively improved, and the seed storage time is prolonged.

Description

[0001] Technical field: [0002] The invention relates to the technical field of seed treatment, in particular to a high oil content crop seed coating agent. [0003] Background technique: [0004] High oil content crop seeds mainly refer to cotton, beans, peanuts and rape seeds, etc., with oil content as high as about 40%. Due to the high oil content of such seeds, the unsaturated fatty acids in the fat will be automatically oxidized into aldehydes, ketones and other substances during storage, resulting in rancidity. Especially in the case of high temperature and high humidity, this change process is carried out faster, and as a result, the germination rate of seeds gradually decreases with the prolongation of storage period. In addition, such seeds have strong hygroscopicity and poor ventilation, and are prone to heat and mold infection. The heated seeds not only lose their germination rate, but also rapidly reduce their oil content. [0005] Invention content: [0006] Th...
