Abstract

The invention discloses a decomposition agent, a preparation method thereof and application thereof in returning straw compost to a field, and belongs to the technical field of green agricultural production. Aiming to solve the technical problems that an existing composting method is complex and is high in labour cost, the invention provides the decomposition agent which is prepared by mixing a probiotics complex microbial inoculant and organic substance fermentation substrate and then sequentially performing anaerobic fermentation and aerobic fermentation; the probiotics complex microbial inoculant is prepared by EM probiotics fermentation; and the organic substance fermentation substrate consists of soybean meal, rice chaff, wheat bran and corn flour. According to the invention,straw, manure, the prepared decomposition agent and soil are sequentially stacked in sequence from bottom to top, and such stacking is performed for multiple layers according to the stacking sequence of the first layer. The decomposition agent is used for returning straw compost to the field.

Description

technical field [0001] The invention relates to the technical field of green agricultural production, in particular to a decomposing agent, a preparation method thereof, and an application of the decomposing agent in straw compost returning to the field. Background technique [0002] At present, the problem of excess crop straw is prominent, resulting in the problem of straw burning, which not only pollutes the environment, but also wastes resources. Straw compost returning to the field can supplement soil organic matter, increase soil fertility, reduce the amount of chemical fertilizers, and achieve sustainable agricultural development. However, the temperature in winter in cold regions is too low, and the rate of decomposition of straw after returning to the field is slow, so simple returning to the field will have adverse effects on the growth and development of crops. Exploring a simple, practical and cost-effective straw compost returning technology suitable for indust...
