【Abstract】 Water saving irrigation theory is used in saline soil and marginal water resource development. Based on discussing the principles of crop response to soil water and salt stress, the hypothesis and methods relevant to crop water salt response model development, and the main characteristics and application effects of the representative models are evaluated systematically in this paper. Several new concepts and new methods and their challenges to traditional hypothesis and theories in relevant research areas in late of the 20th century are introduced. The main points needed to be paid more attention in research area of MCRWS in near future are also proposed.更多还原
