Organic fertilizer production technology

Abstract

The invention discloses organic fertilizer production technology. The organic fertilizer production technology comprises following steps: straw is crushed into pieces with a length lower than 5cm, andis introduced into a straw storage warehouse for further processing; livestock and poultry waste is collected in a storage warehouse for further processing; a fermentation biological bacterium agentis activated for further process; the straw and the livestock and poultry waste are mixed and stirred to be uniform for 2min at a ratio of 1:2, 30kg of the fermentation biological bacterium agent is added for uniform mixing, and water content is adjusted to 45 to 55% so as to obtain a material for fermentation; the material for fermentation is introduced into a fermentation tank, a steam generatoris turned on for heating; thermal insulation treatment is carried out for 180min; a fermentation product is conveyed to a secondary fermentation zone; open air composting natural fermentation is adopted for secondary fermentation for 3 days; after secondary fermentation, an obtained organic fertilizer is introduced into a wet type crushing machine for crushing into powder with a particle size of1mm or lower; drying is carried out until water content is lower than 30% so as to obtain an organic fertilizer. The organic fertilizer production technology is capable of shortening fermentation time, protecting soil, improving soil fertility, and avoiding environment pollution caused by straw burning completely.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to an organic fertilizer production process combining straw, livestock and poultry manure and biological bacteria agents. Background technique [0002] At present, straw utilization is a major bottleneck in agricultural production. A large number of straw utilization measures are mainly power plants to generate electricity and incinerate on-site. There are few power plants that use straw to generate electricity, and the utilization rate of straw is very limited. A large number of structures still use in-situ incineration. Although burning straw can achieve the purpose of returning straw to the field and protecting the soil, it produces a large amount of smoke entraining PM2.5, which seriously pollutes the atmospheric environment. There are two existing technologies for producing organic fertilizers. One is common composting, which has the disadvantages of long fermentati...

[0002] At present, straw utilization is a major bottleneck in agricultural production. A large number of straw utilization measures are mainly power plants to generate electricity and incinerate on-site. There are few power plants that use straw to generate electricity, and the utilization rate of straw is very limited. A large number of structures still use in-situ incineration. Although burning straw can achieve the purpose of returning straw to the field and protecting the soil, it produces a large amount of smoke entraining PM2.5, which seriously pollutes the atmospheric environment

There are two existing technologies for producing organic fertilizers. One is common composting, which has the disadvantages of long fermentation time, large floor space and serious air pollution. The second is the existing mechanized organic fertilizer production. , using less labor, reducing air pollution, and the fertilizer making speed is faster than the composting method, etc., but there are still problems such as long heating time, long fermentation and decomposing time of straw, and large energy consumption.
