All along, China's traditional farming culture and eating habits have formed a food-based aquaculture industry, which consumes 40% of the total grain output every year. On the other hand, the innovative straw-optimized multi-functional composite bacterial fermentation technology does not. To the attention and advocacy of the competent authorities. Li Yutang: The report of the Chinese Journal of Chinese Academy of Sciences on January 15, 2013, entitled "Straw without burning, biochemical good feed" is a big event. All along, China's traditional farming culture and eating habits have formed a food-based aquaculture industry, which consumes 40% of the total grain output each year (up to 50% in the future). At the same time, China's crops produce more than 700 million tons of straw per year. If it can be converted into high-quality feed, it can greatly replace the feed grain and reduce the dependence on protein feed, and resolve the problem of human and animal food competition and straw burning. Due to the commonly used techniques such as straw ammoniation, cellulose lignin and inorganic nitrogen cannot be degraded very well. The quality of finished products is low, and it is difficult to feed pigs and poultry. It is difficult to use it. Therefore, how to make straw into high-quality feed becomes agriculture. A big problem in technology. The research team led by Professor Zhu Baocheng of Hebei Agricultural University has been concentrating on the addition of multi-functional high-density compound microbial fermentation on the basis of straw ammoniation. By deepening the degradation of cellulose lignin and transforming inorganic nitrogen, the energy of volatile fatty acids is greatly increased. The substance, the true protein of the bacteria, various probiotics and digestive enzymes convert the straw into a high-quality feed with high energy, containing more than 12% crude protein and strong digestibility. In addition to fattening cattle and sheep, it can not only save more than one-third of grain and protein feed, but also reduce the cost of breeding by more than 20%. It also significantly improves the quality of livestock and poultry, and reduces air pollution in the house. Get more in one fell swoop. Unfortunately, although this technology has been around for many years, it is still "hidden in the depths of people" and only a few academic groups are advocating. The current problem is: in order to make good use of straw resources, in 2007, the 10 ministries and commissions of the central government set up a working group for the coordination of straw utilization, drafted and issued the “Opinions on Accelerating the Comprehensive Utilization of Crop Straws†by the General Office of the State Council, which proposed the principle of agricultural priority. . In 2011, the National Development and Reform Commission, the Ministry of Agriculture, and the Ministry of Finance jointly formulated the “12th Five-Year Plan for Comprehensive Utilization of Crop Strawsâ€, which made specific provisions on prohibiting the burning of straw, promoting technological innovation, and ensuring policy measures. However, the implementation situation in recent years is not satisfactory; on the one hand, the burning of straw in various places has been repeatedly banned, and some even caused casualties and traffic congestion; on the other hand, innovative straw optimization multi-functional composite bacterial fermentation technology, but not To the attention and advocacy of the competent authorities. In this regard, people in the community have called for: the National Development and Reform Commission, the Ministry of Agriculture and other competent departments should be aware of this technology with a keen scientific vision, and be included in the "Twelfth Five-Year Plan" implementation of innovative technology promotion and key demonstrations as soon as possible. The district construction and production, research and research technology engineering projects support their breadth and depth in policy and funding. Straw grass multi-functional composite bacteria fermentation optimization feed technology, with good fungicide effect, high density, low cost (fermentation of 1 ton of straw fungicide fee 50 yuan), high efficiency, (optimized feed per ton of straw can add 500 More than RMB), long shelf life (more than three years) and easy to operate, wide application and so on. In the application, if the livestock and poultry are combined with the manure and the biogas, and the biogas residue is connected to the three-in-one circulation system, the central government advocates the straw optimization as the “three materials†in the “five materials†( That is, high-quality feed, fertilizer, fuel, other bacteria and base materials and industrial materials), Gongmo (blog, Weibo) 焉! If the country can promote the popularization of this comprehensive technical measure, during the “Twelfth Five-Year Plan†period, half of the country’s annual resources of more than one billion tons of crop straw and grass will be converted into high-quality feed for farming and pastoral farming. China's grain-saving and animal husbandry, environmental protection and energy conservation, improving the quality of livestock and poultry and increasing the income of farmers and herdsmen play a major role. When he was the chairman of the China Association for Science and Technology, Master Qian Xuesen repeatedly discussed and wrote to the author, advocated the development of microbial engineering technology, and converted wastes such as straw, grass, forest branches and leaves into feed, so that China's high-quality feed increased tenfold.
