摘　　要：为明确江西直播棉田杂草发生情况,采用倒置“W”九点取样法对江西柴桑区、武宁县、湖口县15个直播棉田杂草进行抽样调查,采取杂草优势度七级目测法调查杂草群落及危害等级。结果表明,影响赣北地区直播棉田的主要危害性杂草共27种,分属10科,其中禾本科9种,菊科5种,莎草科3种,大戟科3种,旋花科2种,十字花科、木贼科、桑科、车前科、马齿苋科各1种;优势杂草有马唐、千金子、荠菜、香附子、牛筋草、铁苋菜、打碗花、马齿苋、小飞篷、一年蓬、碎米莎草、早熟禾、看麦娘、无芒稗和狗牙根。并提出了“加强棉田土壤整地,搞好农业措施的基础防控,科学施药防除,人工辅助防除”等综合防除策略。In order to clarify the occurrence of weeds in direct seeding cotton fields,the inverted“W”nine-point sampling method was adopted to sample the weeds in 15 direct seeding cotton fields in Chaisang District,Wuning County and Hukou County in Jiangxi,and the seven-level visual measurement of weed dominance method was adopted to investigate the weed community and harm level. The results showed that there are 27 kinds of harmful weeds affecting direct seeding cotton fields in northern Jiangxi,belonging to 10 families,including 9 grasses,5species of chrysanthemum,3 species of sedge,3 species of Euphorbiaceae,2 species of Convolvulaceae,1 species of Cruciferae,Equisetaceae,Moriaceae,Plantaginaceae,Portulaceae;Dominant weeds include crabgrass,millet seed,shepherd’s purse,aconite,cowweed,iron amaranth,bowl beating flower,purslane,small flying canopy,annual canopy,broken rice sedge,kentucky bluegrass,damselflies,tarragon and bermudagrass. The comprehensive control strategies of " strengthening soil preparation in cotton fields,doing well in basic prevention and control of agricultural measures,scientific application of pesticides,and artificial assistance" were put forward.
