| 摘 要： | 在盆栽条件下,研究了苗期调亏灌溉对大豆生长发育和产量的影响.结果表明,苗期中度(土壤含水量为16%～18%)、重度(土壤含水量为13 %～16 %)调亏灌溉处理对大豆整个生育期的株高、叶面积均有一定影响,均显著低于对照(土壤含水量为23%～26%);重度调亏灌溉处理下,地上重和根重均显著低于对照;重度调亏处理根冠比在整个生育期大于中度调亏和对照处理;苗期中度调亏对大豆产量影响不显著, 重度调亏处理对产量影响较大,参试大豆品系辽51064和辽51095分别比对照减产6.69 g/株、10.79 g/株;耗水量随着水分胁迫加强而降低,两个参试大豆品系辽510 64和辽51095,在中度调亏灌溉处理下水分利用效率(WUE)最高,分别为1.49 g/ kg、1.38 g/kg. |

| Abstract: | The influence of regulated Deficit Irrigation(RDI) on the growth and yield were studied at the soybean seedling under the pot condition.The result indicated that the plant height,leaf area,ground and root weight,yield were effected under the different RDI treatments on seedling stage; the plant height and the leaf area were smaller with that of control under moderate and seriously water stress;the weights of ground and root were decreased markedly under seriously water stress;the soybean yield was not influ... |
