摘要
详细分析了作物水分利用效率的内涵 ,回顾了国内外的研究历程及进展 ;在阐述其概念系统的基础上 ,结合作者的实验 ,明确了不同水平上的作物水分利用效率的计算模式 ,为作物水分利用效率的深入研究 ,实现农业高效用水及农业的持续发展提供理论依据。
The connotation of crop water use efficiency (WUE) was analysed in detail in this paper. The research history and development of WUE both at home and abroad was reviewed. On the basis of elaborating the concept system of WUE, the calculating models for WUE at different levels were made clear so as to further the study of WUE, which could provide the scientific basis for the high efficiency of agricultural water use and agricultural sustainable development.
