and Experimental Station of Korla,Ministry of Agriculture and Rural Affairs,Urumqi 830091,China)Abstract:Xinjiang is located in the inland,which is a typical desert oasis ecology. Weed population structure and damaging species are quite different in each ecological region of Xinjiang,and weed management is an important part of crop production. Currently,weed control in Xinjiang mainly relies on chemical herbicides. With the development of modern agriculture,there are many concerns in relation to weed control,such as weed population succession and increasing herbicide resistance caused by the excessive application of chemical agents,prominent problems of herbicide damage,improving of intelligent and mechanized control technology,insufficient research on green comprehensive control technology and expertise of weed control teams. Considering these problems,it is suggested that a systematic monitoring of weed population dynamics should be carried out continuously. The lessons from the research results at home and abroad should be taken into account to strengthen the study of the resistance and its mechanisms on weeds in cotton,wheat and corn. Herbicide damage diagnosis and control technology should be promoted. According to different ecological areas,the appropriate green control technology should be advanced. In order to meet the needs of modern agricultural development,we should strengthen the weed control ability of Xinjiang farmland by strengthening the cooperation of different departments and the training of grass-roots agricultural technicians.

新疆维吾尔自治区位于欧亚大陆腹地,属于典型的绿洲灌溉农业区。是我国绿洲分布最广、面积最大的省区,绿洲主要分布在天山南北麓、昆仑山-阿尔金山北麓、伊犁谷地和额尔齐斯河流域[1]。各绿洲间的气候环境、土壤及水资源等生态因素差异较大,农作物的种植、分布也各有不同。……
