摘　　要：用SC2 0 5 3在不同时期以不同剂量对 3个高产冬小麦品种进行化学杀雄 ,结果表明 :冬性不同的品种对SC2 0 5 3敏感性不同 ;主茎与大蘖处雌雄蕊原基分化～药隔分化期为SC2 0 5 3适宜的喷施时期 ;不同品种适宜喷施时期与剂量有差异 ,冬性较弱的济 92 4 14 2适于在雌雄蕊原基分化～药隔分化后期以 0 .5与 0 .6kg/hm2 喷施 ,在雌雄蕊原基分化～药隔分化期以 0 .6与 0 .7kg/hm2 喷施对冬性中等的鲁麦 2 1比较适宜 ,而在 3个喷施时期以 3个喷施剂量对强冬性的鲁麦 14喷施的杀雄效果均不理想。Three different winterness cultivars of winter wheat were used in the test of spraying period and dosage of SC2053. The results showed that the susceptibility of three different winterness cultivars was different and the suitable spraying period and dosage of SC2053 were different. The most suitable spraying period to three cultivars was from the stage of formation of stamen and pistil to formation of anther separation in its main stem and large tillers. It was favor to the male sterility and fertility that SC2053 either of 0.5 or 0.6 kg/hm 2 to Ji 924142 at the period from the stage of formation of stamen and pistil to later formation of anther separation or of 0.6 or 0.7 kg/hm 2 to Lumai 21 at the period from the stage of formation of stamen and pistil to formation of anther separation was sprayed.
