摘　　要：介绍了非充分灌溉研究的概念理论基础,阐述了非充分灌溉研究中的有限水量在作物生育期内的最优分配、作物-水模型及其敏感指标和土壤水分不足条件下作物蒸发蒸腾量的计算方法,并提出了对非充分灌溉的研究展望。The theory basis of deficit irrigation is introduced. The crop -water production model and its sensitivity indexes for deficit irrigation, the crop evapotranspiration calculation methods and the optimal allocation of limited water among different growth stages under soil-water deficit conditions are summarized. And several opinions about the forecast of deficit are proposed.

关 键 词：非充分灌溉 蒸发蒸腾量 水分生产函数 敏感指标 优化配水
