摘要
本文根据1987—1989年的试验资料,对半干旱地区农田水分平衡进行了分析;同时对不同降水年型的春小麦耗水量和耗水规律作了比较,并分析了不同年份春小麦增减产的水分原因。
Based on the 1987-1989 experimental data, this pater analysed the field water bal-ance in farmlands of the semi-arid areas. Also, it compared spring wheat water con-sumption with its laws in different types of rainfall years, and analysed the cause of watercausing yield reduction in spring wheat in different years.
