Research Progress on Resource Utilization of Rural Straw
Straw is an important biomass resource.China's straw resources are large and widely distributed,but the added value of products is low.This paper summarizes the ways and treatment technologies of straw resource utilization:straw fertilizer is directly or indirectly returned to the field,physical,chemical and biological technology of straw feed,energy utilization technology of straw,straw-based materials and straw energy treatment technology are introduced,and the application effects of various treatment methods are introduced,and the development trend of resource technology is put forward,aiming at promoting the high-value utilization of straw,improving the utilization rate of straw and developing circular economy.
