[0005] Patent No. CN201210435042.9 discloses a biological seed coating agent for rape and its preparation method and application, by applying the technology of biological seed coating agent to rape seeds, and providing relevant fertilizers to provide nutrition for the growth and development of plants; the disclosure No. CN1537425A discloses a kind of rapeseed pelletized coating drought-resistant seed coating agent and its preparation method. Crushed into powder with a fineness of 200 mesh or more; 0.15%-0.40% insecticide, 0.35%-0.65% fungicide, 0.05%-0.15% KHPO, 5%-40% peat and 240.01%-0.03% root powder Evenly mixed and crushed into powder with a fineness of more than 250 mesh. The above two patents are for obtaining seed coating agents, but both have added pesticides or fertilizers, which does not conform to the green agricultural policy advocated by the state. The state advocates the reduction of pesticides and hormones. And the application of inorganic fertilizers to the environment. In addition, the above seed coating agents are all applied to conventional land, and they are all seed coating agents for rapeseed. Therefore, they are not applicable to soybeans growing in saline-alkali land.

Abstract

The invention discloses a seed coating agent for promoting germination and seedling formation of leguminous seeds in saline-alkali soil and a preparation method of the seed coating agent. The seed coating agent mainly comprises a soybean rhizobium solution, a bacillus liquid a, a bacillus liquid b, silk fibroin, peptone and the like. A film is formed outside the seeds before sowing, so that the seeds are helped to resist abiotic stress outside soil, and a protective layer can be formed around rhizosphere during seedling growth, so that the harm of abiotic stress to the seedlings is further reduced, and the leguminous seeds can grow healthily.

Description

technical field [0001] The invention relates to the technical field of seed coating agents, in particular to a seed coating agent for promoting the germination and seedling formation of leguminous seeds in saline-alkali land and a preparation method thereof. Background technique [0002] Population growth, soil degradation and pesticide overuse are major challenges that agriculture will have to face in the coming decades as it relates to global food production. Seed enhancement technologies will play a key role in supporting food security by germinating seeds in degraded environments, reducing seed germination time and increasing crop yields. Significant efforts have been made to date in designing plants that can adapt to different environments and germinate in the presence of abiotic stressors such as soil salinity, high temperature and drought. [0003] The area of ​​global saline-alkali soil is about 950 million hectares, accounting for about 10% of the total land area o...
