【 摘 要 】

Developing water-saving irrigation is an important guarantee for the sustainable development of agriculture. And the research of how to use limited water resources to obtain the best yield, water use efficiency is a hot topic at present. In this paper, the optimum irrigation schedule is achieved by setting different water treatment schemes, optimizing the tomato yield, water use efficiency indexes. The result shows, when soil water rate is controlled within 70%∼75%, 60%∼65%, 80%∼85%, 75%∼80% of field capacity respectively in different developing stages, the tomato yield is the highest, which can reach 54050. 27kg/hm2; the water use efficiency is the highest, which can reach 27. 1kg/m3; and it is the best water-saving, high-yield, high-quality planting treatment.
