轮作对农田杂草的影响研究进展

Research Advances in the Effects of Rotation on Cropland Weeds

轮作对农田杂草的影响引起了学者的广泛关注,为了更好地阐明作物轮作在田间杂草管理中的作用,从轮作对杂草群落和杂草种子库的影响两个方面叙述了国内外的相关研究,总结了轮作对杂草影响研究的特点和存在问题。同时,分析了轮作影响农田杂草的可能机制,提出了研究过程中引起问题的部分原因。另外,还展望了今后的研究方向,指出深入研究不同轮作条件下杂草群落和杂草种子库动态规律是今后的研究重点,统一研究方法、完善研究过程中应用的关键技术是研究过程中应重视的问题,关键机制研究和应用研究是未来研究的发展方向。

The effects of rotation on cropland weeds have aroused extensive attention of scholars. In order to better clarify the roles of rotation in weed management, this paper described the related researches from the aspects of the crop rotation effects on weed communities and weed seed bank, and summarized the main features and problems in existing studies. At the same time, the possible mechanisms of the rotation effects on cropland weeds were analyzed, and the possible reasons for the problems in the courses of the studies were proposed. Also, this article prospected the future research directions. The in-depth studies of weed communities and weed seed bank dynamic regular pattern under different rotation conditions are the focus of future researches. Attention should be paid to the unity of the research methods and the improvement of the key technologies in the study courses. The research of key mechanism and applied research are the future research development directions.
