Problems solved by technology

The fertilizer efficiency of microbial fertilizers is directly affected by quality factors such as the number of effective bacteria contained in the fertilizer and the size of the activity. Only when these beneficial microorganisms are vigorously multiplying and metabolizing can the material transformation and beneficial metabolites be continuously formed and exert their full potential. effect, otherwise it will directly affect the quality of the fertilizer, resulting in a decline in fertilizer efficiency

Abstract

The invention relates to a compound microbial fertilizer having high nutrient content and a preparation method thereof; and the compound microbial fertilizer is prepared by effectively combining an inorganic nutrient, an organic matter and a microbial strain, carrying out disperse coating on the inorganic nutrient by adding kaolin, humic acid and the like in a pelletizing process, then, spraying polyglutamic acid outside particles to envelop, and adding the compound microbial strain adsorbed by a carrier. By means of the method, the compound microbial fertilizer has higher inorganic nutrient content; the effective viable count cannot be influenced; the compound microbial fertilizer having high nutrient content, disclosed by the invention, has an obvious yield-increasing effect; the disadvantage of being slow in fertilizer efficiency of the ordinary microbial fertilizer is overcome; and simultaneously, the compound microbial fertilizer disclosed by the invention has the important functions of improving soil property, increasing soil fertility, promoting plant growth, improving the quality of crops, increasing the disease resistance of the crops and the like.

Description

Technical field [0001] The invention relates to the field of fertilizers, in particular to a compound microbial fertilizer with high nutrient content. Background technique [0002] Long-term use of a large amount of chemical fertilizers results in soil compaction, reduced crop quality, poor taste, and even causes environmental pollution and affects human and animal health. Microbial fertilizers can improve soil structure, increase fertilizer efficiency, create a rhizosphere environment dominated by beneficial microorganisms, overcome continuous cropping and prevent root diseases, promote crop growth, and are important in increasing yield, improving crop quality, increasing crop resistance, and improving soil properties effect. The current research on microbial fertilizers is mostly concentrated in the fields of nitrogen fixation, decomposition of soil organic matter and insoluble minerals, disease resistance and stimulation of crop growth, root symbiotic bacteria and other field...
