There is a 200,000 square meter animal husbandry park in Yang Shulin Township, Nong 'an County, Jilin Province. The adoption of a unique micro-ecological fermentation bed breeding technology model in pig breeding not only completely changed the dirty, chaotic and poor phenomena in traditional breeding methods, but also brought great benefits to farmers.
After scientific research, improvement and popularization in 2000 ~ 2003, the technology of micro-ecological fermentation bed has been successfully improved and held national patents, and has developed to 17 provinces and cities nationwide, with good results. Completely changed the dirty, chaotic and poor phenomenon in the traditional farming method, and the effect was amazing.
Micro-ecological fermentation bed culture technology has been popularized in China for five years and has been recognized by farmers who use micro-ecological fermentation beds in the north and south. The temperature problem is a common concern of many farmers. According to the geographical location and the temperature difference between north and south, the building structure is different. The special strains for fermentation beds are also different. Only with the professional guidance of professional departments can the fermentation bed breeding industry achieve good results.
The patented technology of Jilin Huinong Biotechnology Development Co., Ltd.-raising pigs by fermentation bed has attracted the attention of agricultural departments within five years of its application in aquaculture. Relevant people have visited the micro-ecological enclosure many times, and many domestic media have also reported it. From June 5 to February 2007, seven sets of "Science Park" columns of the Central Committee came to Jilin and Liaoning for on-the-spot follow-up interviews, popularizing the cultivation techniques of micro-ecological fermentation beds.
In cold winter, when the temperature in the north drops to -30℃, the temperature of fermentation bed can be controlled at about 20℃, which shortens the traditional feeding cycle in winter and saves grain 1/3.
During the high temperature period in the south of the Yangtze River in summer, floor-to-ceiling windows are used for ventilation, and some cement torus is adopted to adjust the torus strain, so that the indoor temperature is lower than the outdoor temperature and the high temperature period in summer can be safely passed.
