Preparation method for biological fermentation integrated organic fertilizer

Abstract

The invention provides a preparation method for a biological fermentation integrated organic fertilizer. According to the invention, a composite microbial agent used for straw degradation is pre-fermented and then added into a compost, and preparation of an organic fertilizer is realized through the manner of aerobic fermentation, wherein the composite microbial agent is composed of wheat bran used as a carrier and compound bacteria; and a bacterial liquid comprises the following components: compound bacteria I, compound bacteria II, compound bacteria III, auxiliary compound bacteria and water. The preparation method provided by the invention has the following advantages: high oxygen introduction is realized in the whole process, so an aerobic environment for biological fermentation is guaranteed; strains added for fermentation are microorganisms with strong stress-resisting ability and have a long active period in a normal-temperature condition, so an important theoretical basis is provided for implementation of continuous fermentation; and the composite microbial agent capable of obviously shortening a straw degradation and fermentation period is adopted, so the fermentation period is shortened to 10 days or less. Thus, the preparation method provided by the invention can maximally improve production rate of the organic fertilizer, reduces production cost, and lays a foundation for fermentation production of a straw biological organic fertilizer.

Description

technical field [0001] The invention relates to a technology in the field of agricultural biological fertilizers, in particular to a method for preparing organic fertilizers based on the integration of rural decentralized waste collection and biological fermentation. Background technique [0002] my country's urban agricultural areas have the characteristics of large dispersion and small concentration, which brings a lot of inconvenience to the centralized collection and treatment of crop straws. According to the distribution characteristics of urban agricultural areas, it is particularly critical to carry out the research and development of decentralized straw clean collection equipment and organic fertilizer continuous fermentation technology in agricultural areas. In addition, my country's agriculture has a huge demand for organic fertilizers, but the quality of commercially available organic fertilizers varies, and most of them are made from decomposed and fermented live...
