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 a compound microbial fertilizer with a microbial inoculum permeation and adsorption method. The method comprises the following steps of: preparing a liquid microbial inoculum; preparing a lignin black liquor into organic granules by performing spraying granulation; and compounding the organic granules with a liquid compound microbial inoculum, whereinthe l inoculum; preparing a lignin black liquor into organic granules by performing spraying granulation; and compounding the organic granules with a liquid compound microbial inoculum is added in anamount of 0.5-1.5 percent by weight based on the total weight of a finished compound microbial fertilizer. Production of the compound microbial fertilizer is completed with a method for making a bacterial liquid permeate into the organic granules, and the technical requirements of a product can be met without drying. In the invention, a new path is opened, the convection is broken, a production method of a granular compound microbial fertilizer is partitioned into an organic granule granulating step and an organic granule coating step, a certain viable count in the compound microbial fertilizer is ensured simultaneously, breakthrough of a compound microbial fertilizer product from powdery granules to spraying granulation granules is realized, and foundations are laid for large-scale popularization of the compound microbial fertilizer.

Description

technical field [0001] The invention relates to a method for compound microbial fertilizer, in particular to a method for producing compound microbial fertilizer by utilizing lignin organic granules. 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 the WTO, my country's agriculture has been severely challenged. To develop export-earning agriculture, we must vigorously promote the development of green food and pollution-free food. Moreover, under the impact of the international financial crisis, the traditional chemical fertilizer industry is in deep trouble. Fertilizers have a ver...
