In 2003, I stood in line with the year of agricultural science and technology, experimented with micro-storage technology and was successful. With the approaching of the Olympic Games in 2008, environmental pollution issues are getting more and more attention. However, the stacking of canal, roadside, ground, fieldside, and house edges of crop straws is easy to cause fire, and it is also a kind of environmental pollution in the suburbs. The main sources directly affect the urban environment and people's quality of life. The use of micro-storage technology to convert straw into micro-storage has not only improved the quality of feed, but also solved the problems of inconvenient straw storage and environmental pollution. Test content: The experiment was conducted in two breeding plots in Yanqing County. The experiment was conducted in three stages for micro-storage experiments on three kinds of corn stalks: spring, yellow and dry. Test results: The first phase of micro-repositories was unpacked on October 27, with obvious fruity aromas, soft feeling, and sensory evaluation should be of excellent grade. The second and third stage micro-repositories were unpacked on December 1 and the sensory evaluation was of good grade. Comparison of crude protein and crude fiber in corn stover micro-storage and corn stover: Crude protein—Since the storage time of corn stalk is short (more than one month), water loss is mainly short-term, and crude protein does not change much, so corn stover The micro-preserved crude protein was equivalent to the original corn stalk. As storage time increases, nutrient loss will increase. Crude fiber - Due to the micro-storage equipment for straw extrusion, grinding and other processing, crude fiber is slightly lower than dry straw. Straw micro-storage can preserve the original nutrient composition to the greatest extent, improve the palatability of feed, increase the feed intake of livestock, increase the feed intake rate, and the feed is basically not wasted. The micro-storage technology is very popular among local farmers. At present, there are four sets of equipment to promote the use of micro-storage feed more than 400 tons, a profit of more than 30,000 yuan, and radiation to a number of neighboring breeding communities and farmers. Conclusions: 1. Micro-storage technology can process and store corn stalks (green, yellow, and dry), and solve the disasters and environmental pollution caused by any stacking of stalks, roadsides, grounds, yards, and houses. problem. 2. The micro-storage can preserve the nutrient content of the original straw, improve the palatability of the feed, increase the feed intake, and increase the feed intake. The feed is basically not wasted. 3, micro-storage equipment investment is small, the production cost is low, suitable for different forms of farmers, farming communities use.
