Technology for rapidly decaying rice and wheat straws

Abstract

The invention discloses a technology for rapidly decaying rice and wheat straws. The technology comprises a step of evenly spraying rice bran on the rice and wheat straws so as to utilize the fermentation of the rice bran to decay the rice and wheat straws under the actions of the natural temperature and dews in the night. The technology has the following advantages that the rice bran is easily available in villages and is very cheap, the mixed rice bran and rice and wheat straws can be decayed under a natural temperature condition, no other auxiliary condition is required, and moreover the operation is very convenient. The technology uses agricultural waste (rice bran) to process waste (straws), is environment-friendly, is harmless for human and livestock, and is accord with the ecological circulation requirements of agricultural production.

Description

technical field [0001] The invention relates to a technology for rapidly decomposing rice and wheat straws, in particular to a technology for accelerating the digestion of rice and wheat straws. Background technique [0002] According to survey statistics, the theoretical amount of straw resources in my country is 840 million tons per year, and about 700 million tons of straw can be collected. Straw varieties are mainly rice, wheat, corn, etc. Among them, rice straw is about 211 million tons, wheat straw is about 154 million tons, corn straw is about 273 million tons, cotton stalk is about 26 million tons, oil crop straw (mainly rapeseed and peanut) About 37 million tons, about 28 million tons of bean straw, and about 23 million tons of potato straw. my country's grain production has obvious regional characteristics. The theoretical resources of straw in 13 major grain-producing provinces (regions) including Liaoning, Jilin, Heilongjiang, Inner Mongolia, Hebei, Henan, Hubei...

Problems solved by technology

[0004] Although the comprehensive utilization rate of straw has been greatly improved, it is still very difficult to popularize among rural people, mainly because it is difficult for ordinary people to master the utilization technologies such as feed, biogasification, solidification, and dry distillation of straw. At the same time, a certain amount of capital needs to be invested in the early stage It is used to purchase equipment, store straw resources, etc. In addition, with the support of the above-mentioned technologies, the straw cannot be completely disposed of, and a considerable share of the straw has not been treated and becomes environmental waste. The rapid decomposition technology of rice bran and straw can overcome the above problems. Insufficient, on-site processing of straw, the technology is easy to understand, easy for ordinary people to master, and does not require much investment, and can handle all rural straw
