| The eco-security issue is placed in an important position task in the construction of new rural, not only to improve the environment based on a simple single point of view, but also to consider it on the height of the new energy in rural areas, strengthening the industrial chain of circular economy. Recently, many scholars put forward a development idea of multi-functional and recycling economy in biomass to energy, which is very constructive. Use agricultural and forest residues, environmental pollutants as raw materials, consisting of corn stalk, stockbreeding excrement, forest waste and organic waste and so on, to make it harmless and reclamation. "Studies and Demonstration on the Key Technologies of Hog House with Fermentation Bed for Feeder pigs in Fangzheng" project was launched based on this purpose.Taking advantage of the technology of fermentation comprehensive utilization, energy-saving building technology and waste disposal technology, the project will realize the recycling of material and resource in eco-economic system and solve the heat insulation, fertilizer, energy and environment problems in countryside; giving priority to body with farmer cooperative organization and with the assist of the unit in cooperation, it will mobilize the enthusiasm of the farmer and truly improve peasants'quality, living environment and level.This topic is to be with development office pilot in Fangzheng, providing design scheme, design drawings and assists the farmer to build pig house, in 2009 we built a 35 square meters of ecological pigpen with fermentation, including 21 square meters of growing and fattening pigs fermentation, making use of pig dung manufacturing to realize environmental protection, energy saving, high quality, safe production. We provide 5 good fattening pigs, vaccines and forage etc. After the launch of engineering, we tested ambient temperature, land surface temperature, harmful gases content,the ratio of feed and meat and productivity etc, writed down the situation of feeding and disease in detail. Based on the data processing and get the following conclusions:(1)Around 10 days, the fermentation bed is running to stable state.Data shows, the pigpen with fermentation bed can effectively enhance the environment temperature and the temperature of the earth,it is good for heat prevention in cold season and can reduce the energy consumption.(2)That, the pigpen with fermentation bed can significantly reduce NH3 content, during poor ventilation in cold season, it can effectively control ammonia emissions, purify air environment in pigpen. It is helpful for maintaining the environment quality and reducing piglet disease, provides good living space for pigs. (3)Fermentation technology, significantly increased pig plecata and the feed conversion, improved lean meat percentage, the efficiency of producing meat and the quality, really achieving the goal of high-yield, high-quality and high-efficiency. At the same time, the padding after fermenting as organic fertilizer, can improve crop yields and quality, is up to the mustard of circular economy and the construction of new countryside.(4)This project improved the productivity of pigs, what is more, solved the problems of feces pollution, improved farmers living conditions and the quality of life, and has good economic, ecological and social benefits. This technology can also be used to poultry farming, e.g chickens, ducks, etc.
