Present situation and benefit analysis of the straw recycling in Southwest of China

Currently, Chinese sustainable agricultural development is facing some big challenges that how to promote the present developing pattern, lengthen material transformation chain, increase the utilization rate of material and energy in agricultural system and form a healthy agriculture ecological circulatory system. China is the major country in producing crops as well as in straw. Both high-efficient utilizing pattern of straw and technological system are needed urgently. We point out the status of straw utilization and the main recycling patterns in typical farming area in Sichuan China through the literature review and data collection, combined with field survey. Based on the statistical analysis, with the economic, environmental and social benefits of each utilization way analyzed, this paper proposes the methods and measures to promote recycling utilization of the straw in Sichuan farming area, where is under the theoretically guide on energy-saving, food safety, and pollution control.
