利用土壤水分运移数值计算进行冬小麦灌溉预报

The Irrigation Forecast of Fall Wheat by the Numerical Calculation of the Moving of Soil Moisture

本文根据土壤水分运动原理，通过对冬小麦田间试验及有关资料的分析，建立数学模型，利用计算机对冬小麦田间土壤水分运移进行计算，并利用其预报土壤墒情，以便为决策部门进行适时适量的灌溉，合理调配水资源提供依据。

This paper, following the principle of soil moisture movement,has analyzed the date of field experiment, and built up a mathematics model to calculate the moving of soil moisture in fall wheat field with cumputer,and apply the results for forecasting the field soil moisture. In this way, it can provide the basis for the policy-making organ to allocate water resources reasonably to irrigate properly and timely.
