| 摘 要： | 本文根据野外实测资料，分析了作物根系的生长规律。确定了作物腾发量，并用多元回归分析方法，拟合了作物根系吸水的数学模型，通过对一维土壤水分运动方程采用数值模拟的方法，分析了作物生长条件下层状土壤水分运动过程，与实测值比较认为拟合结果较好。表明所建立的根系吸水模型是合适的。

| Abstract: | The numerical model of the crop root uptake is developed with the help of multiple regression on the basis of the data measured in field.This paper also analyses the wheat root's rule of growth and evaporation.The one-diameter layered soils moisture equation under the condition of plant consumption is simulated,the simulating results are better by comparing simulated results with the data measured in field.It is shown that the numerical model of the crop root uptake is right. |

| Keywords: | rate of crop root uptake regression analysis layered soils |
