Problems solved by technology

An authoritative department estimates that in the next five years, the annual demand for microbial fertilizers will reach 30% of the amount of chemical fertilizers, and the market capacity will reach 42 million tons. However, the current annual production of microbial fertilizers in my country is less than 3 million tons, which is far from being able to meet market needs
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 compound microbial fertilizer from amino acid organic granules, in particular to a method for producing compound microbial fertilizer by adopting slurry spraying and granulating processes, comprising the following steps: preparing liquid microbial agent, granulating waste amino acid solution into organic granules, and compounding the organic granules with the liquid compound microbial agent, wherein the liquid compound microbial agent is uniformly absorbed on the surfaces of the amino acid organic granules, and fermentation liquid accounts for 0.5-1.5wt% of the finished product of the compound microbial fertilizer. According to the invention, the normal method for producing the compound microbial fertilizer is improved, a novel method for producing the granular compound microbial fertilizer by two steps of granulating waste amino acid solution into organic granules and absorbing the liquid compound microbial agent by the amino acid organic granules is provided, and the number of viable bacteria in the compound microbial fertilizer is ensured. The production of the compound microbial fertilizer by the slurry spraying and granulating processes breaks through the production of the powdery compound microbial fertilizer by the disc and roller granulating process, thus a good foundation is laid for improving the commodity value, effectiveness and large-area popularization of the compound microbial fertilizer.

Description

technical field [0001] The present invention relates to a kind of production method of novel granule composite microbial fertilizer, in particular, relates to a kind of amino acid mother liquor produced in the production process of using glutamic acid or monosodium glutamate (glutamic acid is the main raw material for producing monosodium glutamate) through spraying granulation The production method and application of the amino acid organic granules to produce high-efficiency and environmentally friendly granular compound microbial fertilizers. Background technique [0002] Due to the application of a large amount of chemical fertilizers, soil compaction, water quality decline, agricultural products are seriously polluted, and the entire farmland ecological environment and people's living environment are affected. How to maintain the sustainable development of my country's agriculture has attracted great attention from governments at all levels. Especially after my country's...
