| 摘 要： | 利用已建立并经充分验证过的根，冠系统模拟模型，研究了不同土壤水分条件下根、冠之间消长关系，给出了不同１ｍ土体贮水量波动情况下根冠比动态变化模拟结果，并提供了有关试验数据作为佐证，其中有些结论为常规试验不易得到的全新认识，有些结果支持并证实了以往有关结论，均为水分对作物生长实施调控提供了重要依据。

| Abstract: | The root shoot relationships under different soil water regimes were studied by the established simulation model of root shoot system which had been tested widely.The change characteristics of root shoot ratio with the fluctuation of storaged water in 1m depth soil provide some new knowledge which are difficult to obtain by usual experiment and the others supported the past results.The simulation results are compared with the relevant experimental results.All of these results are the important basis for controlling and regulation crop growth by soil water. |
