Problems solved by technology

Since the compound microbial fertilizer contains live bacteria, the drying during the granulation process has a great impact on the number of live bacteria, and because peat and humic acid are mineral organic raw materials, it is more difficult to dissolve after granulation, and the granulation affects the quality of the product. and effects
However, arable land in many places in the north belongs to machine sowing, and powder products cannot be used, so they are not granulated, which directly affects the mass use and promotion of products
[0006] 3. The granulation rate of disc and drum granulation is low, the particles are irregular, and the surface is not smooth, which affects the appearance quality of the product

Abstract

The invention provides a method for producing a compound microbial fertilizer by a microbial inoculum coating method, comprising the following steps of: preparing solid microbial inoculum; adding abamectin waste liquid to an inorganic fertilizer and pelletizing to prepare organic fertilizer particles; compounding the organic fertilizer particles with the solid powdery microbial inoculum, wherein the weight proportion of the microbial inoculum to the finished-product compound microbial manure is 5-15%; and mixing and then drying, wherein the temperature of materials in a drying cylinder is not higher than 80 DEG C. The method for preparing the granular compound microbial fertilizer is divided into two steps of organic granule pelletization and organic granule coating, which ensures the certain viable count in the compound microbial fertilizer; the products of the compound microbial fertilizer realize the breakthrough from powdery form and disc and drum pelletization to guniting pelletization, which lays a foundation for improving commodity value, effectiveness and area promotion of the compound microbial manure; in addition, the invention simultaneously finds out a way with high added value for the resource utilization of the abamectin waste liquid.

Description

technical field [0001] The invention relates to a production process for producing a new high-efficiency and environment-friendly fertilizer, in particular to a method and application for producing granular composite microbial fertilizer by spraying and granulating waste liquid produced from abamectin. Background technique [0002] The compound microbial fertilizer has comprehensive nutrients and can improve the soil and improve the soil compaction caused by the use of chemical fertilizers. Improve soil physical and chemical properties, enhance soil water retention, fertilizer retention, and fertilizer supply capabilities. The beneficial microorganisms in the compound microbial fertilizer enter the soil and form a mutual symbiotic multiplication relationship with the microorganisms in the soil, inhibit the growth of harmful bacteria and transform them into beneficial bacteria, interact and promote each other, and play a synergistic role in the group. The beneficial bacteria ...
