Phenotypic data of plant can reflect the growing of crops, which is one of great significance to guide the integrated water management. In order to study the effect of different fertilization strategy on growth of greenhouse tomato, the common small tomato (Jade) was selected as the research object due to suitable for greenhouse planting. Four kinds of different ratios of water soluble fertilizer were set up to affect the tomato growing. During the test, phenotypic parameters of tomato were collected respectively under the different fertilization levels, including plant height, stalk diameter, number of internodes, number of inflorescence, fruit production and so on. ANOVA single factor analysis method was conducted to analyze the experimental data. The results show that tomatoes with different ratios of fertilization have significant differences. Among which, the tomato plants with high fertilization level get the best production, and normal fertilization level is fit to plant growing with the largest single fruit weight and remarkable economic benefit. At the same time, the growth and fruit yield are more obviously distinguish than the relatively small amounts of fertilizer and no fertilizer. The multiple factors regression with fruit number, height, number of internodes, number of inflorescence and yield were introduced to analysis parameters effective and the best determination coefficient R2 is 0.965. The significant differences order is fruit number, plant height and number of internodes, number of inflorescent. The results of experiment show that the normal level of fertilization is best for growing, and the phenotypic data can provide reference for the establishment of irrigation strategies of the greenhouse tomato growing with fertilization equipment.
