Method for producing functional biological organic base fertilizer by using poultry excrement

Abstract

The invention provides a method for producing functional biological organic base fertilizer by using poultry excrement. The method is characterized in that pig excrement, chicken excrement, humic substances and other raw materials are used as basis, the optimum carbon-nitrogen ratio is adjusted, a deep pond continuous high-temperature aerobiotic dynamic fermentation process is adopted, decomposition inoculant which can promote materials to be decomposed and has the deodorization function is added in the decomposing process, and after the materials are decomposed, functional bacteria are added, so that the functional high-quality biological organic fertilizer is produced. The method has the advantages that a high-efficiency decomposition technology and an aerobiotic fermentation technology system are established, the poultry excrement treatment time is shortened, and production efficiency is improved; and antagonistic action among all functional bacteria is avoided, and all the functional bacteria have the reciprocal symbiosis. All microorganisms can grow and breed at different temperature areas, and exert efficacy mutually, so that the fermentation effect is guaranteed radically, the excrement odor can be effectively removed simultaneously, and the poultry excrement wastes can be quickly decomposed in 7 to 10 days.

Description

technical field [0001] The invention relates to a method for producing functional bio-organic fertilizer products by using livestock and poultry manure, and belongs to the field of new green fertilizers. Background technique [0002] my country has a lot of people and little land. The long-term petrochemical agricultural model has formed a vicious circle of "excessive use of chemical fertilizers-decreased soil fertility-increasing the amount of chemical fertilizers". Due to the long-term excessive application of chemical fertilizers and insufficient input of soil organic matter, the soil carbon-nitrogen ratio is unbalanced. , which deteriorates the living environment of soil microorganisms, the conversion rate of chemical fertilizers is low, and agricultural non-point source pollution is serious. [0003] Among the more than 3 billion tons of livestock and poultry manure and more than 700 million tons of crop straw produced by the farming industry every year, less than 30% of...

[0002] my country has a lot of people and little land. The long-term petrochemical agricultural model has formed a vicious circle of "excessive use of chemical fertilizers-decreased soil fertility-increasing the amount of chemical fertilizers". Due to the long-term excessive application of chemical fertilizers and insufficient input of soil organic matter, the soil carbon-nitrogen ratio is unbalanced. , which deteriorates the living environment of soil microorganisms, the conversion rate of chemical fertilizers is low, and agricultural non-point source pollution is serious

[0003] Among the more than 3 billion tons of livestock and poultry manure and more than 700 million tons of crop straw produced by the farming industry every year, less than 30% of the former is treated harmlessly, and the latter is burned or discarded in large quantities, and the scientific utilization rate is less than 20%

Technical defects of traditional on-site simple composting: on-site simple composting cannot meet the needs of large-scale farming to process a large amount of manure; cannot guarantee the requirements of agricultural production for organic fertilizers; cannot meet the requirements of contemporary farmers for labor conditions; cause certain pollution to the environment

Granular products overcome the disadvantages of poor appearance and low level of powder products, and improve the commerciality of products, but at the same time, they also increase the production cost of enterprises and have a certain impact on the survival of effective bacteria
