Biological nitrogen fixation synergist and use method thereof

Abstract

The invention discloses a biological nitrogen fixation synergist. The biological nitrogen fixation synergist is prepared from in percentage by weight: 0.05-5% of charcoal, 0.01-5% of graphene sol, 0.01-1% of iron nutrient, 0.01-1% of molybdenum nutrient, 0.00001-0.0005% of brassinolide active substance, 0.1-1% of surfactant and the balance stopping. The biological nitrogen fixation synergist provides rich uncombined carbon, can promote colonization of nitrogen-fixing microorganisms, improves the dinitrogenase activity, promotes nitrogen absorption and utilization of plants, and improves the yield. The invention further provides a use method of the biological nitrogen fixation synergist.

Description

technical field [0001] The invention belongs to the technical field of biochemical control, and in particular relates to a biological nitrogen fixation synergist and its application method. Background technique [0002] The air in nature contains about 80% nitrogen, which cannot be directly used by plants in general, but some microorganisms can synthesize nitrogenase, and under the catalysis of nitrogenase, nitrogen can be reduced to ammonia nitrogen, which can be absorbed and utilized by plants. This process is the soil An important source of nitrogen, accounting for nearly 70% of the combined nitrogen on the surface, some of which nitrogen-fixing microorganisms can form a mutually beneficial symbiotic relationship with plants to provide nitrogen nutrition for plants. Therefore, under natural conditions, the combination of plants and microorganisms to form nitrogen fixation has attracted much attention, such as the symbiotic nitrogen fixation relationship between rhizobia a...

AI Technical Summary

Problems solved by technology

[0004] (1) As the most critical factor of biological nitrogen fixation: the reduction of nitrogen fixation activity of nitrogenase

[0005] (2) Due to the competitive effect of fertilizer inorganic ions, there is a lack of electron and proton donors and corresponding electron transport chains necessary for biological nitrogen fixation

[0007] (4) Due to the feedback inhibition effect of chemical nitrogen nutrients, the ammonia formed by microbial nitrogen fixation cannot be transported or transformed in time
