Study on Water Consumption in Summer Corn Field under Condition of Drought

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.
