Abstract： Taking Feicheng peach trees as the test material， a compound nutrient soil conditioner was formed by mixing different proportions of Kaoshan Duoba， chelated iron， Tu Hao Gen and urea. The effect of different proportions of the compound nutrient soil conditioner on the prevention and control of iron deficiency chlorosis in peach trees was studied.The purpose was to provide a reference for fundamentally preventing and controlling the occurrence of chlorosis in peach trees. The results showed that with the extension of time，the SPAD value of peach tree leaves increased after the application of different concentrations of Kaoshan Duoba soil conditioner， and the leaves showed a phenomenon of regreening. Among them， the best effect of preventing and controlling chlorosis was achieved when 100mL of Kaoshan Duoba soil conditioner + 100g of chelated iron + 50mL of Tu Hao Gen τ+100g of urea was applied to the root by irigation at the initial stage of yellowing of the young leaves of the new shoots of Feicheng peach trees
