Method for producing soluble composite microorganism fertilizer

Abstract

The invention provides a method for preparing soluble compound microbe fertilizer. The technical project of the invention comprises fermenting bacillus subtilis, bacillus megaterium and bacillus mucilagimosus krassilm individually. The fermented bacterial liquid is adsorbed by turf separately. Three adsorbed single microbial inoculum is blended and grinded according to the proportion of 1:0.9-1.2:0.9-1.2 to obtain the compound microbial inoculum. The used liquid sediment in the production procedure of gourment powder factory and amino acids manufacturers as lysine plant and the like is disposed to charge trace element raw material and 6%-8% compound microbial inoculum with relative to total weight to obtain the needed compound microbe fertilizer which is easy to dissolve in the water and facilitates to adsorb and utilize plants.

Description

technical field [0001] The invention relates to a production method of a soluble compound microbial fertilizer, in particular to a production method of a compound microbial fertilizer utilizing amino acid production waste liquid sediment. 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 accession to WTO, my country's agriculture has been severely challenged. To develop export-earning agriculture, it is necessary to vigorously promote the development of green food and pollution-free food. As the production material of green food, microbial fertilizer has become a key product promoted by the Min...

Problems solved by technology

An authoritative department estimates that in the next five years, the annual demand for microbial fertilizers will reach 30% of chemical fertilizer consumption, and the market capacity will reach 42 million tons. However, the current annual production of microbial fertilizers in my country is less than 1 million tons, which is far from being able to meet market needs

However, peat and differentiated coal are minerals. Due to the limitation of national resources, large-scale mining will destroy the ecology, and it is difficult to dissolve in the soil. The organic matter and humic acid in it are difficult to be used by crops, which affects fertilizer efficiency. At the same time, peat and differentiated coal The price of the product is also increasing year by year, and the production cost of the product is also increasing year by year.

Moreover, since the raw materials of existing products do not contain nitrogen, phosphorus, and potassium elements or contain very little, nitrogen, phosphorus, and potassium fertilizers are often added during production. A large amount of inorganic ions in the product increase the osmotic pressure, which affects the survival of microorganisms and makes the living bacteria The number is reduced, which affects the product quality

The above shortcomings have affected the promotion of compound microbial fertilizers

[0004] In the process of amino acid production, the discharge of a large amount of highly polluting waste liquid is a problem that has plagued production enterprises for a long time. Among the most serious production enterprises of monosodium glutamate (glutamic acid) and feed additive lysine, a medium-sized production enterprise is taken as an example , the solid sediment in waste liquid treatment can reach tens of tons or hundreds of tons per day. These sediments are very acidic. If they are not properly treated, they will cause serious acidification of soil and water. Some enterprises cannot Pay expensive processing fees and have to be in a semi-stop state

[0005] Some manufacturers of monosodium glutamate (glutamic acid) and feed additive lysine use the waste water after the waste liquid precipitation because it contains a certain amount of soluble nitrogen, phosphorus, potassium nutrients and organic matter, amino acids, and humic acid. Nutrients are sprayed and granulated to produce amino acid fertilizers and organic-inorganic compound (compound) fertilizers. The large, small and powdery scraps screened out during production are difficult to use due to their high return production costs.
