Shell-free pumpkin seed colorful film coating agent and preparation method thereof

Abstract

The invention discloses a shell-free pumpkin seed colorful film coating agent and a preparation method thereof. The coating agent is prepared from 1-2% of thiram, 0.1-0.3% of fludioxonil, 0.1-0.3% ofmetalaxyl-M, 1-4% of a dispersant, 1-3% of an antifreeze agent, 0.1-0.2% of a preservative, 1-2% of a thickening agent, 8-12% of an emerald green color paste, 6-8% of a film-forming agent, 10-12% of green pearl powder, and the balance of water. The invention also provides the preparation method of the coating agent. The seeds coated by the colorful film coating agent are colorful and bright, haveextremely low shedding rate, effectively improve the commodity of shelled pumpkin seeds used as seeds, have good breathability, and can rapidly absorb water and expand after encountering water. The thiram can effectively prevent germs on the surfaces of the seeds and protect the seeds, and the fludioxonil and metalaxyl-M can effectively prevent low-temperature seed powdering, so the germination rate and emergence rate of the pumpkin seeds are guaranteed and increased, the root system is developed, seedlings are neat and strong, stress resistance and disease resistance are improved, and the shell-free pumpkin yield is increased.

Description

technical field [0001] The invention relates to a colorful film coating agent for plant seeds, in particular to a colorful film coating agent for shellless pumpkin seeds and a preparation method thereof. Background technique [0002] Seed coating treatment is to wrap non-seed materials such as fungicides, insecticides, micro-fertilizers, plant growth regulators, colorants or fillers on the outside of the seeds, so as to achieve the spherical shape of the seeds or basically maintain the original shape, and improve the resistance. Reversibility, disease resistance, a seed treatment technology that accelerates germination, promotes seedling formation, increases yield, and improves quality. The coating technology of corn, wheat and other crop seeds is a relatively mature and widely used seed coating technology in the seed industry. However, when the coating technology of corn and wheat is directly applied to shellless pumpkin seeds, the aesthetics and commerciality are not high...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to: aim at the problems that the above-mentioned existing shellless pumpkin seed colorful film coating agent has poor air permeability, the seeds cannot absorb water and swell rapidly after being exposed to water, the coating effect is poor, the emergence rate and seedling retention rate are affected, and the yield is reduced. The invention provides a colorful film coating agent for shellless pumpkin seeds and its preparation method. The coating agent is aimed at the growth and development characteristics of shellless pumpkin seeds, and can improve stress resistance, disease resistance, and germination after coating the shellless pumpkin seeds. rate and emergence rate, increase yield and improve quality
