摘　　要：依据CROPWAT模型结合田间补灌试验资料,采用作物水分响应模型研究辽西半干旱区玉米生育期产量与水分的关系。结果表明:不同生育期水分影响玉米产量依次为灌浆期>开花期>拔节期;实现玉米高产应选择的补灌时期以拔节期+开花期+灌浆期组合为佳,补灌定额为135mm;实现水分高效利用则选择开花期+灌浆期补灌,灌水定额为90mm。According to the CROPWAT model and supplementary irrigation data,using crop-water response model studied the relationship between yield and water in the whole growth period and each growth stage of corn in semi-arid region of western Liaoning province.The results showed that the impact of the water on yield of corn in the growth period is filling stage>anthesis stage>jointing stage.If optimized for high yielding,jointing+anthesis+filling combination irrigation should be selected and irrigation amount ...
