Abstract

The invention relates to a fulvic acid and rhizobium biological type leguminous plant seed coating agent and a preparation method thereof. The fulvic acid and rhizobium biological type leguminous plant seed coating agent is characterized by comprising fulvic acid, a rhizobium culture solution, a film forming agent, trophic factors and the balance of water as raw materials. The preparation method comprises following steps of: adding 5-8% of film forming agent into the balance of water, and heating to 75-85 DEG C to slowly dissolve the film forming agent; then, adding 3-5% of dispersing agent, and adding 0.5-1.0% of trophic factors after the dispersing agent is dissolved; adding 0.03-1.0% of fulvic acid, and cooling to 28 DEG C or so; and finally, adding 3-5% of rhizobium culture solution, and uniformly mixing to obtain the product of fulvic acid and rhizobium biological type leguminous plant seed coating agent. The product has the advantages and effects of promoting the growth of rhizobia, enhancing stress resistance, obviously increasing the survival rate of rhizobia and the competitiveness of pannonibacter phragmitetus, reducing the use amount of chemical fertilizers and pesticides, protecting the environment, improving product quality and ensuring food safety.

Description

technical field [0001] The invention relates to a fulvic acid-rhizobia biotype legume seed coating agent with fulvic acid and rhizobia as main active ingredients, which is particularly suitable for use as a legume seed coating agent and belongs to the field of seed treatment. [0002] The invention also relates to a preparation method of the coating agent. Background technique [0003] The coating agent is wrapped on the surface of the seeds to form a layer of permeable film, which has the functions of preventing pests and diseases, increasing the germination rate of seeds, regulating plant growth, reducing the amount of pesticides, and protecting the environment. Domestically, there are researches on soybean coating agents, such as soybean molybdenum fertilizer coating agent, heavy cropping soybean seed coating agent, etc. These chemical or specific coating agents can improve soybean seed vigor, promote soybean germination, promote soybean root development, enhance seed re...
