Abstract
The invention relates to the technical field of fertilizers, in particular to a compound microbial fertilizer and a preparation method and application thereof. The compound microbial fertilizer is fermentation liquor obtained by mixing microorganisms with a solution A and conducting fermentation. The microorganisms include lactic acidbacteria, acetic acidbacteria, citric acidbacteria, saccharomycetes, bacillus stearothermophilus and bacillus thuringiensis. The solution A comprises an aqueous solution obtained by extracting urokinase and ulinastatin from human urine , and 0.3% of glacial acetic acid and 0.2% of ammonia water are added in the extraction process. The preparation method comprises the steps of strain fermentation culture and strain fermentation liquor mixed solution A fermentation. The application is in the fields of soil remediation and crop yield increase. The compound microbial fertilizer is balanced in nutrition and high in organic acid content, the national standardof the compound microbial fertilizer (liquid) is completely met, the macroelement conversion efficiency is improved by 25%-35%, the use amount of chemical fertilizer is reduced by 1 / 4, and the microbial mechanism and physicochemical properties of soil are effectively improved.
Description
technical field [0001] The invention relates to the technical field of fertilizers, in particular to a compound microbial fertilizer and its preparation method and application. Background technique [0002] Microbial fertilizer refers to a type of fertilizer product that uses the life activities of microorganisms as the core to enable crops to obtain specific fertilizer effects. According to the different types of microorganisms, microbial fertilizers can be divided into bacterial fertilizers, actinomycete fertilizers, fungal fertilizers, algae fertilizers and compound microbial fertilizers. Among them, compound microbial fertilizers refer to the combination of specific microorganisms and nutrients, which can provide , Live microbial products that maintain or improve plantnutrition, increase the yield of agricultural products or improve the quality of agricultural products. [0003] Human urine is an ideal raw material for waste recycling. The urokinase contained in it is ...
