A high-efficiency microbial fertilizer

Abstract

The invention discloses a high-efficiency microbial fertilizer, belonging to the technical field of agricultural fertilizers. The high-efficiency microbial fertilizer is composed of 2-5 parts of Bacillus mucilaginosus, 1-3 parts of phosphate solubilizing bacteria, 20-35 parts of Bacillus subtilis culture, 6-8 parts of Aspergillus awamori culture and 10-15 parts of Lactobacillus plantarum inoculum. The fertilizer can improve the soil; the beneficial microbes in the fertilizer can generate saccharides and plant mucilage; the mineral embryo can be combined with the organic colloids to improve the crumb structure of the soil, enhance the physical properties of the soil and reduce the loss of the soil particles; and the fertilizer can participate in humification under certain conditions, thereby being beneficial to increasing the soil fertility. The product is simple in application method, the consumption is 0.3-1kg per mou, the cost is only 70-100 Yuan / mou, and the product is sprayed on the field surface before irrigation in the seed treatment or growth period.

Description

technical field [0001] The invention relates to a biological fertilizer processing method, which belongs to the technical field of agricultural fertilizers, in particular to a high-efficiency microbial fertilizer and its preparation. Background technique [0002] Microbial fertilizer is a microbial living product that uses microbial life activities and its products to cause crops to obtain specific fertilizer effects. It can improve soil fertility, improve fertilizer utilization, inhibit crops from absorbing harmful substances such as heavy metals and pesticides, and purify and restore soil. It plays an irreplaceable role in promoting the utilization of crop stalks and urban waste, and improving the quality of agricultural products. The efficacy of microbial fertilizers is mainly achieved through the synergistic effect on traditional chemical fertilizers and organic fertilizers, the improvement and activation of soil, and the physiological effects of microorganisms.

AI Technical Summary

Problems solved by technology

[0004] For many years, most of the processing methods of microbial fertilizers only use finished bacterial agents mixed with fillers, lacking fermentation metabolites, which seriously affect the fertilizer efficiency of microbial fertilizer products. For example, the patent application with publication number CN103396252A discloses a compound microorganism containing amino acids Fertilizer, in which the finished microbial agent is composed of Bacillus subtilis, Bacillus licheniformis and Bacillus megaterium mixed in a certain proportion

[0005] Moreover, the agricultural microbial agents currently on the market are mainly single microbial strains, which are difficult to restore the micro-ecological structure. At the same time, the synergy between common strains and crops is weak, which is unfavorable such as improving plant stress resistance and root nutrient absorption. For example, the publication number is The patent application of CN102888356A discloses a method and application of using Bacillus subtilis to prepare microbial fertilizer

Although some compound microbial agents have appeared on the market, their functions are single, or their use methods are limited, and the effect of increasing crop production after use is still unsatisfactory. Composite microbial agent or fertilizer with comprehensive functions and good yield-increasing effect

[0006] Due to the long-term lack of investment in microbial fertilizer research in China, my country's microbial fertilizer industry still has problems such as low overall level, insufficient technological innovation, and unstable product quality and application effects.
