| 摘 要： | 采用对角线5点取样法调查新疆拜城地区冬小麦田杂草发生情况，结果表明：该地区冬小麦地有杂草16科41种，一年生杂草占60．98％，多年生杂草占39．02％，优势杂草为无芒稗、狗尾草、藜，其密度分别为120．7、32．6、14．1株／m^2；冬小麦—青贮玉米、冬小麦—草木樨能够抑制冬小麦地杂草的发生，其中冬小麦套种草木樨抑制杂草效果极显著（P〈0．01）。

| Abstract: | Occurrence of weeds in winter wheat fields was determined by a diagonal five - point sampling in Baicheng region of Xinjiang. There were 41 weed species from 16 families in winter wheat fields of this region,with annual weeds and herbaceous perennials accounting for 61% and 39%, respectively. Dominant species were Echinochloa crusgalli, Setaira viridis ,and Chenopodium glaucum at densities of 121,33 and 14 plants/m^2 respectively. Winter wheat - silage corn and winter wheat - sweet clover rotations decreased the occurrence of winter wheat weeds;winter wheat interplanting with sweet clover substantially decreased weed infestations （ P 〈 0.01 ）. |
