摘 要：
利用气温、降水量和日照时数３个气象要素，建立了土壤水分动态模型。该模型具有简单、准确、使用因子和参数少等特点，易于在实际工作中应用。还考虑了土壤水分过多或过少对作物生长的不利影响，确定了干旱对玉米生育的影响函数，来评价干旱的胁迫作用，并给出了干旱指标和适宜灌溉量的确定方法。最后利用过去两年的观测资料对模式作了检验，效果很好。

摘 要：
In this article, the data of air temperature, the precipitation and the hours of sunshine were used to build a soil water dynamic model. The model is characterized by simple, acurate and using a few of factors and parameters and can be used easily in practice. Considering the negative effect of excessive or short of water on crop growth, the function of drought was defined to evaluate the stress of drought. The methods of defining the drought index, the appropriate irrigation amount were given, too. In terms of observed data of two years, the model was verified to be effective.
