In order to determine the fertilization schedule of nutrient substrate bag-cultivation tomato in solar greenhouse，with a tomato（Lycopersicon esculentum Mill.）cultivar‘Shengluofei’，tomato plant was treated with four kinds of fertilization levels（CK：experience fertilizer application，F1：standard fertilizer level；F2：20% lower than F1；F3：20% higher than F1，which F1 treatment was calculated according to Israel nutrient solution formula of tomato each stage）．The effects of different fertilizer levels on the plant growth and biomass，fruit yield and quality，and nutrient utilization of tomato was investigated．The results showed that at the whole growth period of tomato，there was a significant increase in the plant height，stem diameter，biomass and fruit yield per plant of F2 treatment compared with the other treatments．In addition，N and K nutrient utilization efficiency of F2 treatment was also higher．But the fruit quality between four treatments was not a significant difference iomass and fruit yield per plant of F2 treatment compared with the other treatments．In conclusion，F2 treatment is the best fertilization schedule for nutrient substrate bag-cultivation tomato in this experiment．
