Abstract: The effects of different application methods （spraying, watering, spraying and watering） of compound amino acid fertilizer on net photosynthetic rate, agronomic index and element content （total N, total P, total K, total Mg, total S） on eggplant（Solanum melongena L.） were studied. The results showed that there was no positive effect on net photo synthetic rate of eggplant by applying compound amino acid fertilizer; The fresh weight on the grond and weight of single fruit increased by application of compound amino acid fertilizer, and there was no significant difference among the ways of applying compound amino acid fertilizer; The different application methods of the compound amino acid fertilizers affected the content and distribution of total N and total P, total K and total S. In summary, spraying and watering compound amino acid fertilizer has the best promotion effect to the growth of eggplants.
