摘　　要：At the seedling and beginning flowering stages,2.5% deltamethrin EC was sprayed to control the pests in summer soybean,and its effects on agronomic traits and yield of soybean were analyzed.The results showed that compared with the control,the plant height,branch number,effective pod number,grain number per plant,grain weight per plant,100-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 increased by 13.8%,10.0%,15.8%,16.9%,11.6%,6.0%and 16.9%,respectively;the noneffective pod number of Qihuang 34 and Qihuang35 significantly decreased by 18.5% and 38.7%,respectively.The spraying of 2.5%deltamethrin EC showed no significant effects on the other agronomic traits of the two cultivars.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。
