摘要
本文以冬小麦田间试验数据为基础，采用最小二乘法原理，拟合了冬小麦的水分生产函数模型；通过需水资料的分析整理，揭示了冬小麦的水分效应及需水规律；提出了不同水文年型冬小麦最优灌水方案，可供冬小麦田间管理时参考。
This paper is based on the experimental data of winter wheat in different fields. It quasis the model of the function of water producing by using the least squart criteriond. By the analysis of imformation of water need, both the water effect and the rules of water need are disclosed. It also offers the best irrigation scheme of winter wheat in different hydraulic years,which can be refered in directing the management of winter wheat between fields.
