| 摘 要： | 农田生态系统中杂草与作物争光、争水、争肥,也是各种害虫的寄主,最终影响作物的产量和品质.该文分析小麦绵农6号不同播种量对农田杂草发生种类、发展规律及小麦经济产量的影响,为实现农田杂草的生态管理提供参考.结果表明:麦田杂草群落主要由看麦娘、荠菜、猪殃殃、蔊菜、短辐水芹、碎米荠和野薄荷等构成,其中看麦娘、荠菜、猪殃殃和野薄荷等为主要杂草.在低播种量B1(4.47g/m2)时,杂草生物量较高,增大播种量B4(17.88g/m2)可抑制麦田中杂草数量的发生.适宜的小麦播种量B2(8.94g/m2)和B3(13.41g/m2)能抑制麦田杂草的发生,降低生产成本,获得较高的经济产量.

| Abstract: | Weeds are potential competitors of the crop for light,water and fertilizers,and also provide host plants for various insect pests,which results in decreased crop yield.In this experiment,wheat cv.Miannong 6 was sown at four different sowing rates in order to highlight the principle of weed occurrence and boost ecological management of weeds.The results showed that the weed community in the wheat field was mainly composed of Alopecurus aequalis,Capsella bursa-pastoris,Rorippa indica and Oenanthe benghalensis... |
