Embodiment 1

[0021] (1) Preparation of composite microbial strains: The mass percentages were 60% of chaff, 20% of wheat bran, and 20% of corn flour, and mixed evenly in proportion. The main ingredients are fully mixed, first aerobic fermentation for 7 days, and then anaerobic continuous fermentation for 7 days, dried at low temperature, moisture content ≤ 12%, bagged and sealed for storage.

[0022] (2) Pre-fermentation: Add the inoculum of 1.5% of the compound microbial strains described in step (1) into the organic fertilizer raw material, mix evenly, pile up to a height of 1.5 meters and supply oxygen for 8 days, during which time the pile is turned over every day deal with. Organic fertilizer raw materials and their corresponding mass percentages are: crop straw 30%, poultry manure 15%, animal and plant residues (including kitchen waste, crop residues, etc.) 30%, peanut bran 8%, pond mud 10%, urea 0.5%, shell powder 3%, magnesium sulfate 0.5%, slaked lime 2.5%, zeolite powder 0.5%. ...

Embodiment 2

Abstract

The invention aims at providing compound microorganism humic acid fertilizer special for organic cultivation and a preparation method thereof. The compound microorganism humic acid fertilizer special for the organic cultivation is high in fertilizer efficiency, rapid in absorption and capable of improving physical and chemical properties of soil and improving disease resistance of crops. The preparation method is environmentally friendly, efficient, short in fermentation cycle, low in cost and easy to operate. The fertilizer special for the organic cultivation is prepared by inoculating compound microorganism strains into fertilizer raw materials and conducting fermentation. The fertilizer special for the organic cultivation is prepared from, by mass, 20%-40% of weeds or straw, 10%-20% of feces of livestock and poultry, 20%-40% of animal and plant residuals, 5%-10% of peanut bran or bean pulp, 10%-20% of pond sludge, 0.5%-1% of urea, 2%-4% of shell powder or calcium superphosphate, 0.5%-1% of magnesium sulfate, 1.5%-2.5% of slaked lime and 0.5%-1% of zeolite powder. The method comprises the steps of preparation of the compound microorganism strains, prefermentation and post-maturation fermentation. The compound microorganism humic acid fertilizer special for the organic cultivation and the preparation method thereof can be applied to the technical field of microorganism fermentation fertilizer manufacturing.

Description

technical field [0001] The invention relates to the technical field of microbial fermented fertilizer production, in particular to a compound microbial humic acid fertilizer special for organic cultivation and a preparation method thereof. Background technique [0002] Humic acid is a type of organic substance formed by the remains of animals and plants through microbial decomposition and transformation, as well as a series of geophysical and chemical interactions. It is mainly extracted from weathered coal, lignite, and peat. Organic agriculture is to comply with certain organic agricultural production standards, not to use genetically engineered organisms and their products in production, not to use chemically synthesized pesticides, fertilizers, growth regulators, feed additives and other substances, and to follow the laws of nature and ecology The principle is to coordinate the balance of planting and breeding, and adopt a series of sustainable agricultural technologies ...
