摘　　要：采用蒸渗仪针对沈阳地区潮棕壤土条件下,不同控制型灌溉处理对大豆生长发育、产量和水分生产效率的影响进行分析,找出了适合当地条件的大豆优化控制性交替灌溉制度,为该技术在沈阳乃至东北地区的推广和应用提供理论依据。结果表明,控制性交替灌溉抑制了大豆地上部分的生长,处理2的产量最高,比处理1增产6.84%,节水8.85%,处理3最节水单产量最低,确定处理2为最优灌溉制度的方案。The lysimeter was adopted to investigate growth, yield and water use efficiency of bean on aquic brown soil in Shenyang under different treatments of controlled alternate irrigation. The results indicate that controlled irrigation restrained the growth of over ground part of bean effectively. Compared with treatment 1 （irrigation quota：M）, treatment 2 （irrigation quota：2/3 M） increased yield by 6.84%, and decreased water consumption by 8.85 %;treatment 3（irrigation quota：1/2 M） consumed the least water and its yield was also the lowest. Therefore, treatment 2 was determined as the optimal irrigation system.
