摘　　要：四川地处中国西南内陆,地跨亚热带至亚寒带气候带,四川麦类种植以冬小麦为主,另有少量春小麦、大麦,种植面积133.3万hm2左右,草害发生面积106.7万hm2以上,目前化除面积占栽培面积的60%以上。四川省麦田杂草种类有80种以上,分属20余科,以禾本科、菊科、十字花科、石竹科杂草种类居多。由于耕作制度改变及多年连续使用同类除草剂,农田杂草种群变化和群落演替加速。除草剂品种亦从以前的几个老品种发展到现在的20多个品种,特别是引进了苯磺隆、精唑禾草灵、炔草酸等安全高效的新型除草剂,基本满足了四川省麦田化除的需要。Sichuan Province is located in the southwest China,it crossed over climate zones from subtropical to subfrigid. Winter wheat occupied the main part among wheat crops growing in Siehuan Province, only a small part of spring wheat and barley distributed in this province. The whole planting area of wheats is about 1. 333 million hm2, the weeds oecur- renced area is above 1. 067 million hm^2. At present,the area of chemical control is over 60% of the total wheats cultivat- ed area. The weeds types in wheat field in Siehuan Province consists of above 80 species, which belongs to about 20 fami- lies respectively, mairdy distributed in the family of Poaeeae, Asteraceae, Crueiferae, and Caryophyllaceae. Because of cropping system change and continuous use of same kind of herbicides for many years, the change of weeds population and succession of community in farmland accelerated. The herbicide types used also developed from a few old types to above 20 types at present, especially brought in some new safe and high efficiency types of herbicide including tribenuron - methyl, fenoxaprop - p - ethyl, and clodinafop - propargyl, which basically meeted the needs of weeds chemical control in wheat field in Siehuan Province.
