摘    要:就节水农业技术体系及作物自身高效用水在节水农业中的地位进行了论述。提出作物高效用水的基本原理在于一定生育阶段适度水分亏缺后覆水作物可以产生生理、生长和产量形成上的补偿效应,促使水分利用效率显著增高。本文还对提高作物水分利用效率的若干技术途径作了介绍与展望。

关 键 词:节水农业  作物高校用水  补偿效应

Abstract:Two current issues of the technical system for saving water in agriculture and the importance of crop high efficient use of water in water-saving agriculture were discussed in this paper. Highlight on the basic principle of crop high efficient use of water is as follows: after suffering light-moderate water deficit in a given growth stage and rewatering to the suitable conditions, crops produce compensatory effects on physiological growth and yield formation, which promote crop water use efficiency obviously. Several technical approaches and perspectives on the improvement of crop water use efficiency were also prospected.
Keywords:water saving agriculture  crop high efficient use of water  compensatory effects
