摘　　要：旱作水稻田中杂草的发生是影响旱作水稻产量的一个重要因素。为解决杂草生长影响旱作水稻发育的问题,调查了旱作水稻田间杂草发生情况,并进行了四种常用除草剂组合试验,同时调查除草剂的药害情况。结果表明:旱作水稻田杂草种类多,数量大。3%氯氟吡啶酯乳油80 ml/667 m^(2)+50%二氯喹啉酸可湿性粉剂100 ml/667 m^(2)组合作茎叶处理对旱作水稻田间杂草的防除效果好,在后期除草剂安全性调查中表现良好,是此试验的最优组合。The occurrence of weeds in dry cultivation of rice is an important factor affecting out put of dry cultivation of rice.In order to solve the problem that weed growth affects the development of dry cultivation of rice,investigated the occurrence of weeds in the field of dry cultivation of rice,carried out a test of four common herbicide combinations,and at the same time investigated the harm of herbicides.The results showed that the species and quantity of weeds were large.The combination of 3%chlorofluoropyridine ester 80 ml/667 m^(2)+50%dichloroquinoline acid wettable powder 100 ml/667 m^(2) in stem and leaf treatment had the best effect on weed control in rice field.It performed well in the later investigation of herbicide safety and was the optimal combination of this experiment.
