摘　　要：在盆栽条件下,研究了花期调亏灌溉对大豆生长发育和产量的影响。结果表明花期不同强度、不同时间调亏处理对株高、叶面积、根重、产量、根冠比等均有影响,且不同品种性状表现差异各异。耗水量随着控水强度加大、控水时间延长而降低,水分利用效率也变化明显,其中7d中度控水处理WUE最高。随着控水强度和控水时间的延长,经济系数有逐渐增大的趋势。综合上述研究,辽51064和辽51095均以7d中度调亏处理（土壤含水量为19%~21%）为适宜。品种抗旱方面,辽51095的抗旱性优于辽51064。The influence of regulated Deficit Irrigation （RDI） on the growth and yield was studied at the soybean flowering under the pot condition. The results indicated that the plant height, leaf area, ground and root weight, yield were effected under the different RDI treatments in flowering stage. Also the differences in performance of different varieties had different characters. The water consumption reduced with the water intensity and watering times, and WUE also changed obviously, the highest in the moderate control water treatment after 7 days. Along with the intensity and time of controlled water, the economical coefficients had the increased gradually tendency.
