植物水分利用效率提高途径研究综述

日益严重的水资源短缺已成为世界性环境问题之一，严重影响世界农林产业的可持续发展。提高植物水分利用效率（WUE），是实现有限水资源高效利用、促进全球农林产业可持续发展的重要战略措施。文中从修剪、地表覆盖、亏缺灌溉、施肥、外源ABA施用和品种选育6个方面综述了提高植物水分利用效率途径的国内外研究情况，以期为在日益严重的水资源短缺条件下提高农林植物WUE、实现有限水资源的高效利用和农林业可持续发展提供借鉴。

Research on Approaches to Improve Plant Water Use Efficiency

Increasing serious water deficit has become one of the major environmental problems worldwide that had influenced the sustainable development of agriculture and forestry in the world. Thus, improving water use efficiency (WUE) of crops and forest trees is of great strategic importance in achieving efficient water resources use and the sustainable development of agriculture worldwide. The paper made an overview of the national and international research on the approaches to improving plant WUE in terms of pruning, mulching, deficit irrigation, fertilizer application, extraneous ABA and variety breeding, with the expectation to improve the plant WUE in the increasing shortage of water resources and provide references to efficient use of limited water resources and sustainable development of agriculture and forestry.
