| 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 influenced under moderate water stress, while it was decreased obviously under the seriously water stress. The water consumption of the test entry was decreased with water stress strengthen; the yeild of test entry, Liao 51064 and Liao 51095, were decreased 6.69 g/plant and 10.79 g/plant respectively. The WUE of Liao 51064 and Liao 51095 were the highest under moderate water stress, 1.49 g/kg, 1.38 g/kg respectively. |
