北方平原地区可耕地比重大、人均耕地少、土质肥沃,是我国重要的粮食基地,主要种植玉米、高粱、小麦、水稻等农作物,秸秆产量非常大。但是,秸秆综合利用方面总体水平仍然较低,效益较差,甚至就地焚烧的现象在各地还大量存在,不仅造成资源浪费、环境污染,还严重威胁交通运输安全。因此,加强秸秆综合利用的研究,努力推进秸秆的资源化、商品化,实现变废为宝,是一个紧迫而重要的现实课题。
The arable land in the northern plains area is large, with less arable land per capita and fertile soil. It is an important grain base in China. It mainly produces crops such as corn, sorghum, wheat and rice. The output of straw is very large. However, the overall level of comprehensive utilization of straw is still low, the efficiency is poor, and even incineration in various places still exists in large numbers, which not only results in waste of resources and environmental pollution but also seriously threatens the traffic safety. Therefore, it is an urgent and important practical issue to strengthen the research on the comprehensive utilization of straw and strive to promote the resource utilization and commercialization of straw and to achieve the goal of turning waste into waste.
