Abstract：In order to figure out the effect of water regulation during fruiting period on cherry tomato yield and quality，this paper took cherry tomato‘Qianxi’and ‘Hongyu’as experimental material and studied the effects of 3 treatments with different relative soil water contents（40%-50%，60%-70%，and 80%-90%）on cherry tomato quality，yield and water use efficiency in winter-spring crop and autumn-winter crop in solar greenhouse．The results showed that the contents of soluble solids，soluble sugar，titratable acid，VC and water use efficiency of cherry tomato were significantly increased along with the increasing of soil relative water content．But，the leaf net photosynthetic rate，stomatal conductance，chlorophyll content，single fruit weight and total yield would show a changing tendency of first increasing then decreasing along with the reducing of soil relative water content．Combining entropy weight method with TOPSIS method，the paper comprehensively analyzed various indexes of cherry tomato including quality，yield and water use efficiency．The optimum relative soil water content was 40%-50% during cherry tomato fruiting period.
