Abstract: At present, water has become the main factor of limiting agricultural development in Northwest China, and the problems of low water use efficiency, increased cost, reduced yield and quality caused by blind irrigation have become the main limiting factors for the sustainable development of agriculture. This paper focused on the deficit adjustment irrigation of tomato, which is the mainly cultivated horticultural crop in Northwest China, analyzed the effects of irrigation methods, irrigation amount and irrigation period on the tomato agronomic traits, quality and water use efficiency, and summarized the research progress in the effects of water-controlled irrigation methods and techniques on tomato yield and quality in Northwest China, aiming to provide a reference for the sustainable development of horticultural crops in Northwest China.
