The new technology of straw utilization developed by Shandong Straw Bioengineering Technology Research Center - "Bioreactor" technology has been successfully applied in 17 counties (cities, districts) such as Dong'a and Cangshan, and has achieved good economic, ecological, and social benefits. . This technology adopts biotechnology to convert straw into crops, such as organic and inorganic nutrients such as carbon dioxide, heat, and disease-resistant spores, which can significantly improve crop ecological environment and promote crop growth and development. The first is to improve the comprehensive benefits of agriculture and significantly increase the income of farmers. The technology has been introduced into Daejeon production demonstration for three years, and has been widely used in 7,000 greenhouses and 1,000 acres of orchards. Practice shows that a 50m 8m greenhouse using this technology can increase production by an average of 50%. The second is to reduce production costs and improve the quality of agricultural products. After the application of this technology, the supply of carbon dioxide is sufficient, and the temperature and the ground temperature increase, and beneficial microorganisms multiply, and the resulting disease-resistant spores and straws produce a large amount of organic and inorganic nutrients after maturity, which makes the crop grow robustly and has an enhanced disease resistance. Local application shows that under normal circumstances, the use of this technology can save more than 50% of chemical fertilizers, pesticides, about 70%, can significantly improve the quality of fruit and vegetables, fruit and vegetable appearance and taste have improved significantly. The third is to open up new ways for the utilization of crop stalks, which has significant ecological benefits. Annual output of straw is about 55 million tons in Shandong Province, and a large amount of remaining straw is discarded and burned, and it cannot be used rationally. If this technology is adopted, about 5,000 kilograms of straw can be digested per mu of fruit and vegetable, thereby increasing the utilization rate of straw, and at the same time effectively solving the problems of environmental pollution, fire caused by burning of straw, threatening highway traffic, and taking off and landing on airplanes. Fourth, the operation is simple, the investment is small, the amount of straw conversion is large, and it is easy to promote.
