作物水分利用率影响因素及其研究进展

摘要

综述了作物水分利用率的研究进展。在探讨水分利用率内涵的基础上，阐述了作物水分利用率的影响因素如作物，环境因素，化学制剂，栽培措施和耕作制度等人类活动等影响因素，重点分析了作物种间和品种间、土壤因素和化学制剂对作物水分利用率的影响。%The research advance on the influencing factors of crop water use effi-ciency (WUE) was reviewed in this paper. Based on the discussion on the conno-tation of crop WUE, the influencing factors of crop WUE, such as crop, environ-ment, chemicals, cultivation measures, cropping systems, etc, were elaborated. A-mong them, the species and varieties of crop, soil and chemicals were discussed in detail.
