农作物秸秆还田研究现状及其有效还田方式展望

近年来，随着作物联合收割机的推广应用，农作物秸秆直接还田数量迅速增加，但农作物病虫害大面积发生并且日趋严重，同时农作物秸秆焚烧现象依然存在，农作物秸秆禁烧工作形势依旧严峻。为了寻求有效的农作物秸秆还田方式，结合农业生产实际及国内外相关研究结果，本文对农作物秸秆还田的意义、研究现状进行简单综述，重点对农作物秸秆不同还田方式对土壤及作物带来的利弊进行讨论，最终提出就地堆肥技术和新式联合作业机械的应用将会是解决当下秸秆还田中存在的诸多问题的有效途径。

Straw Returning and Its Effective Returning Method: Research Progress

Recently, the direct return of crop straw increased rapidly with the increasing application of combine. But the crop diseases and insect pests occurr and become increasingly serious. In addition, the phenomenon of burning crop straw still existed, and the work of bidding straw burning in spot is very hard. To finding the effective methods for straw returning, the significance and research status of straw returning was reviewed, and the advantages and disadvantages of different straw returning methods for the soil and the crop were discussed emphatically, which were based on the actual agricultural production and the correlated studies at home and abroad. Finally, this article put forward that the in-situ compost technology and application of a new type of combine machine would be effective methods for solving the problems in straw returning.
