摘　　要：在大豆苗期和初花期喷施2.5%溴氰菊酯乳油防治夏大豆害虫,测定其对大豆农艺性状和产量的影响。结果表明:齐黄34控制区株高、分枝数、有效荚数、单株粒数、单株粒重、百粒重、产量,分别比对照区显著增加9.3%、25.8%、15.8%、26.8%、33.2%、9.1%、33.0%,无效荚数显著降低18.5%,药剂处理对齐黄34其它农艺性状无显著影响;齐黄35控制区株高、分枝数、有效荚数、单株粒数、单株粒重、百粒重、产量,分别比对照区增加13.8%、10.0%、15.8%、16.9%、11.6%、6.0%、16.9%,无效荚数显著降低38.7%,药剂处理对齐黄35其它农艺性状无显著影响。At the seedling and beginning flowering stages , 2 .5%deltamethrin EC was sprayed to control the summer soybean pests .Its influences to agronomic traits and yield of soybean were analyzed .The results showed that compared to the contrast , the planTheight , branch number , available pod number , grain number per plant , grain weight per plant , hundred -grain weight and yield of Qihuang 34 significantly increased by 9 .3%, 25 .8%, 15 .8%, 26 .8%, 33 .2%, 9 .1%and 33 .0% respectively , while those of Qihuang 35 in-creased by13.8%, 10.0%, 15.8%, 16.9%, 11.6%, 6.0% and 16.9% respectively; the invalid pod number of Qihuang 34 and Qihuang 35 significantly decreased by 18 .5%and 38 .7%respectively .The other agronomic traits of the two cultivars did not change significantly .
