Biological sweet sorghum seed pelleting agent and preparation method thereof

Abstract

The invention discloses a biological sweet sorghum seed-pelleting coating agent, which comprises the following components in percentage by weight: 20 to 30 percent of compound bacteria culture, 5 to 10 percent of streptomycs micuoflavus culture, 0.03 to 0.07 percent of plant growth regulating substance, 6 to 10 percent of super absorbent resin, 0.05 to 0.15 percent of micronutrient element, 55 to65 percent of attapulgite and 3 to 5 percent of water-soluble adhesive. The biological sweet sorghum seed-pelleting coating agent can be used for preparing a biological sweet sorghum seed-pelleting agent, and the biological sweet sorghum seed-pelleting agent can absorb salt in the soil and immobilize the salt in vivo of organisms of efficacious colony so as to reduce the salt around sweet sorghumseeds and saline soil damage; simultaneously, the efficacious colony is propagated in the soil so as to activate mineral nutrition in the soil and increase mineral nutrition for the seeds; and the secretion of the efficacious colony in the propagating process has the effect of regulating substances, and can improve the anti-salt capacity of the sweet sorghum seeds and the germination rate.

Description

technical field

[0001] The invention relates to a seed pelletizing method, in particular to a sweet sorghum seed bio-pellet coating agent and a sweet sorghum seed bio-pellet prepared by the coating agent. Background technique

[0002] Sorghum is the most salt-tolerant crop among grain crops such as wheat and corn, and it is also the most suitable crop for the development of saline-alkali land. The poor salt tolerance of sweet sorghum is mainly manifested in the germination and seedling stage. First, the seeds are damaged by the salinity of the surface soil after sowing, and the seedlings cannot germinate, resulting in rotten buds; Seedling. But as long as the seedlings are kept, as the plants grow, the root system will gradually develop, and the salt tolerance of the plants will increase. In addition, the middle and late stages of growth are in the rainy season, the soil salt content will decrease, and the salt damage will be alleviated. Overcoming salt damage in the buddi...
