Embodiment 1

[0029] 100kg of wheat straw is crushed to less than 15mm, add pig manure and urea, control the C / N ratio of the mixed material to 15:1, spray water until the moisture content is 70%, and add the first composite microbial agent with a raw material amount of 1wt% , mix evenly, compost and ferment for 1 to 3 days, and the temperature of the material rises to 55°C. The second composite microbial agent with a raw material amount of 1.5wt% was dispersed with water, and evenly sprayed onto the pile, and the temperature of the pile was raised to 60°C within 24 hours, and then maintained at 60-70°C for 5 days, during which the pile was turned every 2 days. After 7 days, the temperature of the material began to drop, and the finished organic fertilizer was obtained after being spread out to dry properly. The material was all black or dark brown, soft and elastic when held by hand, easily broken after drying, and had a slight fragrance or fermented smell.

Embodiment 2

[0035] 100kg of corn stalks crushed to less than 20mm, add pig manure and ammonium nitrate, control the C / N ratio of the mixed material to 35:1, spray water until the moisture content is 60%, add the first composite microorganism with a raw material amount of 2.5wt% Bacteria, mix evenly, compost and ferment for 3 days, and the temperature of the material rises to 55°C. The second composite microbial agent with a raw material amount of 2.5wt% was dispersed with water, and evenly sprayed onto the pile, and the temperature of the pile was raised to 60°C within 24 hours, and then maintained at 60-70°C for 5 days, during which the pile was turned every 2 days. After 10 days, the temperature of the material began to drop, and the finished organic fertilizer was obtained after being aired moderately. The material was all black or dark brown, soft and elastic when held by hand, easily broken after drying, and had a slight fragrance or fermented smell.

Embodiment 3

[0041] 100kg of corn stalk powder crushed to less than 20mm, pig manure and ammonium nitrate, control the C / N ratio of the mixed material to 20:1, spray water until the moisture content is 65%, and add 0.05wt% of raw materials for the first compound Microbial agent, mix evenly, compost and ferment for 1 to 3 days, and the temperature of the material rises to 55°C. The second composite microbial agent with a raw material amount of 5wt% was dispersed with water, and evenly sprayed on the pile, and the temperature of the pile was raised to 60°C within 24 hours, and then maintained at 60-70°C for 10 days, during which the pile was turned every 3 days. After 5 days, the temperature of the material began to drop, and the finished organic fertilizer was obtained after being spread out in a moderate amount of air. The material was all black or dark brown, soft and elastic when held by hand, easily broken after drying, and had a slight fragrance or fermentation smell.

Abstract

The invention relates to a method for preparing an organic fertilizer by using plant residues as a raw material. The method comprises the following steps: crushing the raw material to below 20mm, stirring and mixing the broken material with animal wastes or an inorganic fertilizer; controlling the C / N ratio of the mixed materials to be (15-35) to 1 and the pH to be 6-9; adding water, so that the moisture content in the mixed materials in the step (2) is 55-70wt%; adding a first composite microbial agent to ferment; after once fermentation, raising the temperature of windrows to above 50 DEG C; and spraying a water-dispersed second composite microbial agent to ferment for the second time. With plant residues heap corruption (composting) as a biological process for succession of a microbial community, through inoculation of exogenous complex microbial agents, efficient decomposition on agricultural wastes is facilitated; different composite microbial agents are respectively added at different composting stages; and a small amount of additives (animal wastes, urea, ammonium nitrate and the like) are added, so that the composting speed is increased, and the quality of the product organic fertilizer is really improved.

Description

technical field [0001] The invention relates to a method for producing organic fertilizer, in particular to a method for preparing organic fertilizer by using residues as raw materials, and belongs to the field of biological fertilizers. Background technique [0002] Organic fertilizer refers to the use of various animal wastes (including animal manure, animal processing waste) and plant residues (cake fertilizer, crop straw, fallen leaves, dead branches, peat, etc.), using physical, chemical, biological or a combination of the three. Some treatment technologies, through certain processing techniques (including but not limited to composting, high temperature, anaerobic, etc.), eliminate harmful substances (pathogens, pest eggs, weed seeds, etc.) to achieve harmless standards A type of fertilizer formed. [0003] At present, the fermentation time for most high-quality organic fertilizer composts in my country to reach the harmless target is generally 45 to 60 days, which is ...
