Cucurbita pepo seed colorful film coating agent and preparation method thereof

Abstract

The invention discloses a cucurbita pepo seed colorful film coating agent and a preparation method thereof. The coating agent is prepared from the following raw materials in percentage by weight: 1-4%of a dispersing agent, 0.5-1% of a wetting agent, 1-4% of an anti-freezing agent, 0.2-0.5% of a preservative, 0.1-0.2% of a thickening agent, 18-20% of color paste, 18-20% of a film-forming agent, 18-20% of pearl powder, 1-2% of an amino acid water-soluble fertilizer and the balance of water. After the cucurbita pepo seeds are coated with the coating agent, the seeds are colorful and bright; thecucurbita pepo seeds used as seeds are good in air permeability, and can rapidly absorb water and expand after encountering water, so that the germination rate and the emergence rate of the cucurbitapepo seeds are guaranteed and improved, the root system is developed, the seedlings are neat and strong, the stress resistance and the disease resistance are improved, and the yield of cucurbita pepois 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 zucchini seeds and a preparation method thereof. Background technique [0002] With the development of the zucchini industry for seeds in my country, the planting area of ​​zucchini is expanding year by year, and the demand for seeds is large. It is difficult for zucchini seeds to rotate crops during the seed production process. A certain amount of field pathogens will remain on the melon strips and seeds. If the seeds are not sterilized after harvesting, these pathogens will germinate when they encounter suitable living conditions after sowing in the next year. In turn, disease occurs, causing difficulty in seed germination or seedling death. Moreover, if the soil humidity is high after sowing and encounters low temperature, it is easy to cause underground powder seeds and rotten seeds, which will affect the emergence rate and se...

Problems solved by technology

[0006] The object of the present invention is to: aim at the above-mentioned problems that the existing zucchini seed colorful film coating agent has poor air permeability, the seeds cannot quickly absorb water and swell after being exposed to water, the coating effect is poor, the emergence rate and seedling retention rate are affected, and the yield is reduced. A coating agent for zucchini seeds and a coating method thereof. The coating agent is aimed at the growth and development characteristics of zucchini seeds. After coating the zucchini seeds, the seeds are bright, silky and smooth, and can improve stress resistance, disease resistance, germination rate and Germination rate, increase yield
