摘　　要：以大豆品种垦农5号、垦农18、垦鉴豆21、东农42为材料,研究了植物生长调节剂对不同大豆品种某些生理指标、产量性状和产量的影响。结果表明:叶面喷施调节荆促进了大豆叶片的光合速率,提高了大豆叶片的可溶性糖、可溶性蛋白含量;增加了大豆植株的干物质积累,对大豆产量构成因素株英数、株粒数、百粒重等具有一定的调控作用,提高了大豆产量。调节剂对不同大豆品种增产幅度不同,其中垦农5号、垦农18、垦鉴豆21产量与对照相比差异达到显著水平。Taking Kennong 5,Kennong 18,Kenjiandou 21 and Dongnong 42 as experiment materials, the effect of regulator on soybean physiological characteristics, yield characters and yield were studied. The result indicated that when applied growth regulators, the photosynthetic rate was obviously promoted, the soluble protein and the soluble sugar content of soybean were increased;the yield components such as pod per plant, seed weight per plant and 100-seed weight were improved. Compared with the contrast, the yield of Kennong 5, Kennong 18 and Kenjiandou 21 reached 0. 05 significant levels.
