摘　　要：黑龙江省是农业大省,也是秸秆产出大省。目前,黑龙江省秸秆综合利用以还田为主,燃料化、饲料化为辅。但由于当地平均气温低、还田技术粗糙等因素导致水稻秸秆处理难、利用率不高。本文总结了黑龙江省秸秆资源化利用的几种方式,综述了不同秸秆还田方式对水稻产量及土壤养分的影响,并对水稻秸秆还田利用进行了展望。Heilongjiang is a major agricultural and also a major straw production province.At present,returning straw to field is the principle of comprehensive utilization of straw in Heilongjiang Province,supplemented by fueled and feed oriented,which is in line with the law of sustainable agricultural development.However,due to low average temperature,rough returning technology and other factors,straw treatment is difficult and utilization rate is not high.Several ways of straw resource utilization were summarized in this paper,and the effects of different straw returning methods on rice yield and soil nutrients were reviewed,and the future development direction of rice straw returning in Heilongjiang Province was prospected.
