To clarify the application effect of different proportions of commercial organic fertilizer replacing chemical fertilizers in rice production in Tongcheng City, using Y-liangyou 900 as the experimental material, 5 substitution ratio treatments were set up. Through a randomized block field experiment, the influence on the yield components, yield and economic benefits of rice was explored. Both 25% and 50% substitution of commercial organic fertilizer for chemical fertilizers were economically feasible fertilization methods. Among them, the 50% substitution had the best comprehensive effect and could provide scientific fertilization basis for the green, high-quality and efficient production of Y-liangyou 900 in Tongcheng City.
