Abstract: The experiment of different water and top fertilizer combination for tomato cultivated in greenhouse were studied in long season cultivation over summer.The results showed that water irrigation had significant effects on tomato yield.Higher water irrigation could attain higher yield and dry matter,but water produce efficiency and dry matter productivity in high water irrigation treatments were much lower than that in middle water irrigation treatments.With the same top dressing fertilizer mixture treatments,the contents of chlorophyll in leaves and nutrient qualities of fruit might diluted by more water.Considering yield,water using efficiency and cost,the best soil water content was 35%-45%(V/V),the economic and suitable top dressing fertilizer combinations were(NH4)2SO4+K2SO4 or CO(NH2)2+K2SO4,the proportion of N:K2O=1:1.2.

Key words: Tomato, Long season cultivation over summer, Water irrigation quantity, Fertilizer mix ratio
