| 摘 要： | 近年来，水分不足是限制我国北方干旱和半干旱区粮食生产的重要因子。生物节水是实现进一步提高作物水分利用效率的关键环节和潜力所在。笔者就作物水分利用效率的内涵和不同品种间水分利用效率差异的生理生态机理进行了综述，并提出了水分利用效率的研究方向。目前应进一步深入研究作物高效用水生理调控机理和抗旱节水鉴定评价技术与指标体系，为培育高WUE品种提供理论基础。 |

| Abstract: | Water shortage is an important factor that restricts food production in arid and semi- arid area in North China. Biological water –saving is a key link in improving crop water use efficiency. The paper summarized signification and studies of differency mechanism of WUE among differenct species of crops, and next study advisies were put forward: in Huabei Plain of north China, we should study anniversary WUE of deep soil moisture under deficit irrigation conditions. At present, we should furtherly study physiological regulation mechanism of high-WUE crops and evaluation system of drought-resistancing and water-saving for cultivating high-WUE species. |
