中文摘要: 本文根据1983年10月—1986年6月的试验资料,从产量与耗水量的关系上确定最佳耗水量。同时对籽粒产量、秸秆产量、水分利用效率和灌水费用等进行综合评判,确定最大经济效益的水分处理。并对不同生育阶段的耗水规律进行分析,为田间水分管理和气候评价提供依据。

Abstract:According to the data of experiment from October, 198S to June, 1986, the paper analyzed and determined the optimum water consumption from the relationship be-ween yield and water consumption. It also multievaluated the different treatments from grain yields, straw yields, water use efficiencies and irrigation costs and determined the optimum treatment The results obtained from the two methods are the same. The law of water consumption during the different stages for winter wheat is analyzed and it is useful to water management of crop field and climatical evaluation.
