Research Advances on the Measures of Integrated Straw Utilization
This study explained the content of integrated straw utilization and summarized five ways of straw utilization (i.e.fertilizer,fodder,matrix,energy and industry material) and analyzed the research progresses and problems of the integrated straw utilization.Furthermore,it concluded four questions that needed further studies,i.e.research on the mechanisms of the improvement of soil fertility after straw returning,the improvement and development of agricultural machinery mating to straw utilization,the improvement and development of technology that can match different measures of integrated straw utilization,and the development of regional measures of integrated straw utilization and their benefit evaluation.The aim was to provide guidance and reference for development of measures of integrated straw utilization.
