摘要

In order to provide a reference for the development of the substrate cultivation and irrigation system in sunlight greenhouse,the experiment with drip irrigation on cherry tomatoes as the experimen-tal object was carried out,with total of 5 irrigation treatments,each repeated 3 times.Experiments de-termined cherry tomato plant height,yield,irrigation water use efficiency and water consumption.The results show that the plant height,water consumption and water consumption intensity in the whole growth period increased with the increase of irrigation.T1 yield was the lowest,T3 yield was the hi-ghest,and water use efficiency was maximized.Yield,irrigation water use efficiency and water use ef-ficiency were characterized by the changing law of“small at both ends and big in the middle”.It came to the conclusion that the optimum water supply in the whole growth period of the winter and spring crop of cherry tomatoes is 305.66 mm,and that the relationship between the yield and water consump-tion can serve as cherry tomato water production function at the whole growth stages.This study ana-lyzed the relationship between cherry tomatoes of the substrate cultivation in sunlight greenhouse and water consumption,which provides a theoretical basis for the reasonable guidance of crop irrigation in greenhouse.
