%X Crop water production functions, including the type of water supply and the type of water consumption, under dynamic optimal management of fertilizer supply were derived from the water and fertilizer experiment of corn.The relations among the corn yield,water use efficiency,water consumption,and waetr supply were analyzed by the index of water consumption production elasticity.In addition,the function under dynamic fertilizer supply and the function under general fertility level were compared and analyzed.It was pointed out that the crop water production function in different year-types was difference,and it still needs a deeper study.
