Embodiment 1

[0020] A compound microbial fermented inoculant for fast decomposing of mulberry branch, comprising following active components: A bacterium, B bacterium, C bacterium and D bacterium, the mass ratio of A bacterium, B bacterium, C bacterium and D bacterium is 3: 1:3:2, Bacteria A includes Trichoderma viride, Aspergillus oryzae and Aspergillus niger with a mass ratio of 1:1:1, Bacteria B is Streptomyces thermopurpurinda, C bacteria is Saccharomyces cerevisiae, and D bacteria is Bacillus subtilis.

[0021] The preparation method of above-mentioned composite microbial fermentation inoculant comprises the following steps:

[0022] S1: Carry out expanded cultures on Trichoderma viridans, Aspergillus oryzae, Aspergillus niger, Streptomyces thermopurinadin, Saccharomyces cerevisiae and Bacillus subtilis respectively, to obtain the fermentation broths of the above six bacterial strains respectively;

[0023] Among them, Bacillus subtilis is cultivated with nutrient gravy, and the prepa...

Embodiment 2

[0036]In this example, the mulberry branches were crushed in March, 2019, and the composite microbial fermentation inoculant was prepared on May 15, 2019, and the moisture content, carbon content and nitrogen content of the crushed mulberry branches and chicken manure were measured on May 24, 2019. On May 27, 2019, the compost fermentation of the mixed material was carried out. The crushed mulberry branches and chicken manure are mixed according to the dry matter ratio of 1:1. According to the previously measured carbon content and nitrogen content, the C / N is adjusted to 25:1 with urea, and then 5% of the total mass of the compound microbial fermentation agent is added. , and adjust the water content to about 65%, mix it evenly and place it in a plastic foam box, cover the lid to carry out compost fermentation, and cover the outside of the foam box with a film.

[0037] Measure the temperature in the fermentation box every morning at 10 o'clock from the next day, and turn the...

Abstract

The invention relates to the technical field of organic fertilizer production, and discloses a compound microbial fermentation inoculant for rapid decomposition of mulberry twigs. The compound microbial fermentation inoculant comprises the following active components of A bacteria, B bacteria, C bacteria and D bacteria in a mass ratio of 3: 1: 3: 2, wherein the A bacteria comprise trichoderma viride, aspergillus oryzae and aspergillus niger in a mass ratio of 1: 1: 1; the B bacteria are streptomyces thermoviolaceus; the bacteria C are saccharomyces cerevisiae, and the bacteria D are bacillus subtilis; the invention also discloses a preparation method of the composite microbial fermentation inoculant. The invention also discloses a method for preparing a mulberry twig organic fertilizer byusing the composite microbial fermentation inoculant. The method is high in fermentation speed, low in cost, relatively simple in preparation and fermentation processes of the mulberry twigs, economical and environment-friendly, and capable of degrading the mulberry twigs into the mulberry twig organic fertilizer in a short time, so that resource waste is reduced, and the problems that the fermentation time is long and the quality of finished products is low and cannot meet the industrialization requirement during traditional natural rot returning and landfill decomposition of the mulberry twigs are solved; and the problems of agricultural pollution and the like are solved.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer production, in particular to a compound microbial fermentation bacterial agent and a preparation method thereof, and a method for preparing mulberry branch organic fertilizer. Background technique [0002] my country has a history of thousands of years of planting mulberry and sericulture, and the resources of mulberry branches are abundant, with an annual output of up to 10.4 million tons. In the production process of mulberry leaves, in order to increase the output of mulberry leaves and promote the germination of mulberry branches, the mulberry branches need to be pruned several times a year. Therefore, a large amount of mulberry branches are produced in the mulberry leaf production area every year. The traditional treatment methods are to burn the mulberry branches in the field, return them to the field after natural rotting, and landfill them for maturity. These processing methods ...
