Liquid composite microbial fertilizer and its preparation method

Abstract

A liquid composite microorganism fertilizer and the preparation method thereof belong to the field of the microorganism fertilizer technique. The invention uses four microorganisms of bacillus subtilis, bacillus magaterium, silicate bacterium and Streptomyces Jingyingensis for mixed-zymolysis and is combined with soluble nitrogen, phosphorus and potassium to prepare the liquid composite microorganism fertilizer. The fertilizer can be used for all type of soil and crops, the application effect on vegetable, fruit is optimum, and the fertilizer has the effects of improving the soil structure, increasing the water-keeping and fertilizer-keeping capability of the soil, and better increasing the production and improving the crop quality.

Description

technical field [0001] The invention relates to a liquid compound microbial fertilizer and a preparation method thereof, belonging to the technical field of microbial fertilizers. Background technique [0002] In 1891, Beijerinck completed the pure culture of rhizobia and nitrogen-fixing bacteria for the first time, and began the production and application of microbial fertilizers. In 1895, the commercial rhizobia inoculant was launched on the market (trade name Nitrogen). From the 1930s to the 1940s, the United States, Australia, and the United Kingdom all had inoculum manufacturers. In 1930, the sales of rhizobia inoculants in the United States reached 1 million US dollars. After the 1950s, more than 70 countries in the world, including China, began to research, produce and use rhizobia inoculants, and the area continued to expand. In the 1970s, a series of research work on beneficial microorganisms such as nitrogen-fixing bacteria, phosphorus-solubilizing bacteria and po...

Problems solved by technology

But its disadvantage is that using the above three types of fertilizers alone can only solve one aspect of the nutrition required by plants.

The main problem of using the existing process to produce microbial fertilizer is that the equipment for the separate fermentation of each strain has a large investment and a long production cycle, resulting in high production costs and complicated production processes.
