【摘要】 杂草危害农作物的生长和发育,而大量施用除草剂会造成环境污染和增加杂草抗药性。利用植物相互间化感作用控制杂草非常有效,抑草植物通过释放化感物质并与杂草竞争生存环境,进而对杂草发芽和生长产生抑制作用。轮作、耕作等措施影响植物残茬化感物质的释放,造成抑草效果不同。化感育种是解决杂草危害的最有效途径,可使植物具有对杂草抑制作用的化感性状。更多还原

【Abstract】 Weeds is very harmful to the growth of crops,and the utilization of herbicides will lead to environmental pollution and development of herbicide resistance in weeds.Allelopathy among plants is an effective way to control weeds.Weeds germination and growth are suppressed by allelochemicals released from smothering plants and environmental competition with smothering plants.In addition,the release of allelochemicals can be influenced by the measurements of rotation,tillage and other ways,which leads to different levels of weeds suppression.Breeding for smothering plants which possess allelo-pathic potentials is the most effective way to alleviate or eliminale adverse effects of weeds,which can incorporate allelo-pathte characteristics into plants to suppress weeds.更多还原
