| 摘 要： | 采用与传统的五点取样法不同的倒置“Ｗ”９点采样法，对黑龙江省北部豆麦轮作区大豆田杂草发生危害情况进行了调查。结果表明，该地区大豆田杂草有１７科４１种。其中阔叶杂草１４科３５种，占８５．４％，禾本科４种占９．８％，鸭跖草科１种，木贼科１种，种占２．４％。相对多度达１０以上的杂草依次为，稗草、鸭跖草、间荆、铁苋菜、香薷、反枝苋、藜、卷茎蓼、苍耳等９种。其中前７种相对多度达２０以上，可视为当地大豆田的优势杂草。

| Abstract: | Soybean field weed survey was conducted using an inverted W- Sampling frip pattern with 9 sampling points in the north region of Heilongjiang province. Of the 41 weed species recorded in soybean fields, 85. 4 % accounted for broadleaved weed and 9. 8 % for the grass family. Based on the analysis of their relative abundance, 9 species were important weeds in the area. Barn yard grass (Echinochloa crus-galli ) and day flower(Cwnmclina communis ) were the most abundant weeds. |
