| 摘 要： | 为了考虑随机因素(气象因素等)对冬小麦灌溉的影响，用时间序列方法建立了蒸发蒸腾量的随机模型，并将其导入田间水量平衡方程，推导出冬小麦灌溉的随机模拟模型。将该模型用于商丘市李庄乡的冬小麦灌溉，其灌水量与实际情况较为符合，最大误差仅为4.7%，可用于制定冬小麦的灌溉计划。

| Abstract: | In consideration of the effects of stochastic factors, such as meteorological factors and the like, on winter wheat irrigation, the stochastic model of evapotranspiration, developed by using time series method, was introduced into the field water balance equation and the stochastic simulation model for winter wheat irrigation was derived thereof. The application of this stochastic simulation model in the water-saving irrigation of winter wheat in the Lizhuang Town of Shangqiu City indicated that the results had accorded fairly well with the actual situation of winter wheat water requirement. The biggest error margin is 4.7 percent only, and the stochastic simulation model can be used for the irrigation plan of winter wheat. |
