Composite microbial inoculum for preparing biological bacterial fertilizer and preparation method thereof

Abstract

The invention relates to a microbiological composite bacterial inoculum and a preparation method thereof, in particular to the microbiological composite bacterial inoculum used for preparing a biological bacterial fertilizer. The microbiological composite bacterial inoculum is prepared by culturing Rhodop seudanonas palustris, Candida utilis, Lactobacillus acidophilus, Bacillus subtilis and Streptomyces microflavus var. lactosus which are disclosed in a culture catalogue of the China Center for General Microbiology Culture Collection (CGMCC), wherein the serial number of the Rhodop seudanonas palustris is 1.2352; the serial number of the Candida utilis is 2.1180; the serial number of the Lactobacillus acidophilus is 1.1854; the serial number of the Bacillus subtilis is 1.1630; the serial number of the Streptomyces microflavus var. lactosus is 4.0891; and the weight ratio of the Rhodop seudanonas palustris to the Candida utilis to the Lactobacillus acidophilus to the Bacillus subtilis is 1:0.5:0.5:0.1. When used for preparing the biological bacterial fertilizer, the composite bacterial inoculum can effectively decompose and release crude fibers and other nutrient components in straws and livestock manure; and the prepared biological organic fertilizer can condition the soil, increase the activity rate of microorganisms in the soil, avoid soil hardening, improve the permeability of the soil, play a role in production increasing, and effectively solve the problem of the area source pollution of agricultural wastes in rural areas.

Description

technical field

[0001] The invention relates to a microbial composite bacterial agent and a preparation method thereof, in particular to a microbial composite bacterial agent for preparing biological bacterial fertilizer. Background technique

[0002] The emergence of bio-organic fertilizers uses beneficial microorganisms in the soil to improve the micro-ecological system of crops and soil, releases the rich insoluble phosphorus and potassium in the soil, or converts difficult-to-use substances such as crop straws into usable The effective nutrients used can not only alleviate the contradiction between fertilizer supply and demand, but also improve the situation of ecological environment deterioration, and provide the possibility for the development of green ecological agriculture. It started. Biological fertilizers emerged in my country in the late 1980s. However, due to the fact that most of them are single bacteria and have single functions, they cannot fully solve the prob...
