In recent years, Ningxia Hui Autonomous Region has used agricultural and forestry waste stalks to process fuel, and used farm dung and crop stalks for mixed anaerobic fermentation to produce biogas and organic fertilizers, effectively promoting the promotion and application of comprehensive straw utilization technology in the region. According to reports, starting from 2017, the autonomous region has incorporated the comprehensive utilization index of crop straws into the evaluation and assessment content of ecological civilization construction goals in 5 cities. Beginning this year, the establishment of the national, provincial, city, county (district) level four straw resource utilization ledger construction work. After hard work, the comprehensive utilization rate of crop straw in the region now reaches 85.15%.
It is understood that in terms of policy support, on the one hand, the implementation of a subsidy project for comprehensive utilization of crop straws, starting from 2018, an annual budget of more than 80 million yuan, the return of mechanized rice straw stubbles to the field, mechanized picking of corn and other major crops Subsidies are provided for bundling, crushing and deep turning back to the field, and straw storage, storage and processing; subsidies of 20 yuan per mu for mechanized deep turning and returning fields, and 50 yuan per ton for mechanical picking up, bundling, storage and processing. On the other hand, the Yinbei saline-alkali land agronomic improvement project was implemented, and a million-mu acres of saline-alkali land straw fertilization improvement funds in Yinbei were arranged for 22 million yuan. The implementation of the vegetable industry project and the demonstration and promotion project of the application of straw bioreactor technology will arrange an annual fund of 5 million yuan and a subsidy of 500 yuan per mu. For forage feed storage and processing business entities, new agricultural business entities and breeding households that receive and store more than 100 tons of straw will be given a subsidy of 100 yuan per ton.
In terms of technical support, it has formulated and formulated feed regulation technical regulations such as silage, ammoniation, enzyme storage, and micro storage, forming a batch of straw yellow storage kiln storage technology, mechanized straw picking and baling (envelope) technology, bioreactor technology, Typical demonstration model of agricultural waste utilization, such as smashing and deep turning technology. A number of forage forage processing and distribution centers have been established throughout the region, and a forage forage processing, production and supply system of "planters + processing and distribution + breeders" has been initially formed.
