Pelletized coating and preparation method thereof

Abstract

The invention discloses a pelletized coating and a preparation method thereof. By utilizing the characteristics of seeds of brassicaceous vegetable Chinese flowering cabbage, and combining the occurrence of major plant diseases and insect pests of the Chinese flowering cabbage, the seeds of the Chinese flowering cabbage are accurately wrapped with fungicide and insecticide in a layered way; after seeded, the seeds with the pelletized coating of the Chinese flowering cabbage crack within a short time in presence of water to form bowl-shaped structures, and release the fungicide and the insecticide, thus controlling the plant diseases and insect pests, and protecting the germination of the seeds of the Chinese flowering cabbage and the growth of seedlings. The seeds with the pelletized coating of the Chinese flowering cabbage comprise 5-20% of brighteners, 30-60% of insecticide layers, 5-40% of fungicide layers and 15-30% of the seeds of the Chinese flowering cabbage in sequence from outside to inside.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a pelletized coating and a preparation method thereof. Background technique [0002] The pelletized coating technology of crop seeds began in the United States in the 1940s, was introduced to Europe in the 1960s, and was widely used in developed countries such as Europe and the United States by the end of the 1980s. Vegetable seeds coated with pellets are currently the most widely used in production. For a wide range of crops, the processed seeds have the same size and smooth surface, are suitable for mechanical sowing, can save more than 30% of seeds, and can increase yield by 8% to 20%. At present, more than 50% of the vegetable seeds in developed countries have been pelletized, and the research on seed pelletization technology in my country started late. Progress, but the development is relatively slow. At present, tomato and lettuce are mainly used in production. The seed pelleting...

AI Technical Summary

Problems solved by technology

At present, more than 50% of the vegetable seeds in developed countries have been pelletized, and the research on seed pelletization technology in my country started late. Progress, but the development is relatively slow. At present, tomato and lettuce are mainly used in production, and the seed pelleting of cruciferous vegetables is only in the research and development stage, and the production application is blank.
