摘要
施用氮肥和秸秆还田是常见的农业栽培措施,氮肥和秸秆的合理利用对提高作物产量具有重要作用。过量施用氮肥不仅会影响作物产量,还会对生态环境造成负面影响。适当的减量施氮配合秸秆还田,不仅可保证作物产量,提高资源利用效率,而且还可减少对环境的危害。综述了华北地区减量施氮和秸秆还田对小麦生长的影响,提出了存在的问题,并对今后相关研究进行了展望。
Applying nitrogen fertilizer and returning straw to the field are common agricultural cultivation measures.The rational utilization of nitrogen fertilizer and straw plays an important role in improving crop yield.Excessive application of nitrogen fertilizer will not only affect crop yield,but also have a negative impact on ecological environment.Appropriate reduction of nitrogen application combined with straw returning can not only ensure crop yield and improve resource utilization efficiency,but also reduce the harm to environment.The effects of reduced nitrogen application and straw returning on wheat growth in North China were summarized,the existing problems were put forward,and the related research in the future was prospected.
