摘要
农田杂草的生长明显地依赖于活动种子库。文章综述了国内外农田杂草种子库的研究进展,主要分析了除草方式、耕作方式以及农作方式对农田杂草种子库的影响。现有的研究表明,化学与机械结合的防治措施能更好地控制杂草;免耕使分布在土壤表层的种子比例提高;有机栽培体系下杂草种子库最大。最后,提出了国内在该领域中的研究方向。
The weed growth in farmland obviously depended on the active seedbank. This paper reviewed the study progress on farmland weed seedbank, mainly analyzed the effect of different weed management strategies systems, tillage systems and farming systems on farmland weed seedbank. The present results show that chemical combined mechanical methods control weed well than other practices. The no-till system had the largest portion of the seedbank in the top layer of soil. Weed seedbank size was the largest under the organic system. At last, the future study fields were proposed.
