Problems solved by technology

The current formulas of straw composting are uneven, especially the differences in fermentation agents, which lead to incomplete nutrient decomposition and incomplete sterilization of compost, etc.
[0004] In particular, for some specific crop straws (such as broad bean straw), the composting effect of the existing compost formula is poor

Abstract

The invention discloses a broad-bean straw compost composition and a piling method thereof. The composition comprises the following ingredients in parts by weight: 75-95 parts of sundried broad bean straw, 135-155 parts of sundried faeces, 1 part of a fermentation bacteria liquid, and 52-72 parts of water, and the fermentation bacteria liquid is formed by mixing penicillium chrysogenum, bacillus subtilis and trichoderma viride according to the weight ratio of 2:2.5-3.5:2.5-3.5. According to the technical scheme, the fermentation inoculum is optimized, the optimized fermentation bacteria liquid is strong in pertinency, thorough decomposition of broad bean straw nutrition is realized, thorough sterilization is realized, and thus the compost turning-over frequency is reduced, and the step of subsequently adding an inoculum is avoided.

Description

technical field [0001] The invention relates to the technical field of composting, in particular to a broad bean straw compost composition and a stacking method thereof. Background technique [0002] my country is a country rich in straw resources. According to the statistics of relevant departments, the annual amount of recyclable straw resources is as high as 600 million tons, of which the annual amount of broad bean straw in Fujian Province is about 150,000 tons. However, most of the stalks were directly burned by farmers on the farmland, which not only caused a waste of important resources, but also brought serious pollution to the environment that could have been avoided. How to efficiently utilize straw resources has become a research hotspot. At present, my country's straw utilization technology is mainly divided into two directions: direct return of straw to the field and straw composting technology. Straw returning directly to the field is a relatively simple trea...
