中文摘要: 根据田间试验结果,分析干旱年份夏玉米不同发育阶段耗水状况,对比了不同日降水量对玉米田3米剖面的水分分布状况的影响,讨论了土壤失墒过程中的不同深度水分的变化以及土壤水分对玉米干物质积累的影响,为干旱年份玉米水分的科学管理提供依据。
中文关键词: 干旱，夏玉米，耗水量
Abstract:Based on the results of field experiment, the analysis of water consumption during various growing phases in an arid year is made. The influences of different daily rainfall on distribution of soil water on three-meter profile are compared. The variation of soil layers in different depth in processes of soil water losing and its effect on accumulation of dry mass are discussed. The result could provide a foundation for management of soil water in the field of summer corn in arid year.
