Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] Such as figure 1 As shown, the present invention is based on the fact that biostimulants can stimulate the natural process of plants. Substances such as microbial beneficial bacteria are used as important components of seed biostimulants, and their development and utilization will help improve seed vitality and enhance seed germination and seedling resistance. ability, and can continuously affect the yield and quality of plants in the later stage. The preparation and application method of the salt-resistant biostimulant for improving the germination of corn seeds involved in the present invention includes ecological investigation and collection of bacteria source samples, strain isolation and screening, strain purification, research on the characteristics of target strains, determination of growth-promoting ability of strains, and identificatio...

Abstract
The invention relates to the field of seed science, in particular to a preparation and application method of a seed biostimulant SB-MGW6. According to the invention, an important strain, namely Bacillus cereus MGW6 is separated and screened from extremely dry soil near Ming Great Wall in Shandan County in Gansu Province, and is then purified and identified; research results show that the strain has the capabilities of salt resistance, nitrogen fixation, phosphorus dissolution, indoleacetic acid production and the like; the seed biostimulant SB-MGW6 can be directly prepared by utilizing the bacterial liquid of the strain, and the germination and seedling emergence capabilities of corn seeds in saline-alkali soil can be effectively improved by seed soaking-moisturizing and re-drying treatment. The seed biostimulant SB-MGW6 can be widely applied to corn production in saline-alkali soil.
Description
technical field [0001] The invention relates to the field of seed science, in particular to a preparation and application method of a seed biostimulant (Seed Biostimulantof Ming Great Wall 6, SB-MGW6). Background technique [0002] In recent years, biostimulants have become an extremely fashionable term in the global agricultural materials market. According to the definition of international organizations, a biostimulant is a substance containing certain ingredients and microorganisms, which, when applied to plants or the rhizosphere, have the effect of stimulating natural processes in plants, including enhancing / Benefits nutrient absorption, nutritional efficacy, abiotic stress tolerance, and crop quality regardless of nutrient content. In Europe, the use of biostimulants has involved fruit trees (citrus, olives, grapes, etc.), vegetables and fruits (broccoli, peppers, cucumbers, strawberries, tomatoes, melons, etc.), food crops (potatoes, wheat, corn, rapeseed, etc.) ) ...
