In order to study the effects of two amendments on soil environment and applet growth of acidified orchard, in this study, an field experiment was conducted with two amendments, and two treatments were set up:no amendment and with amendment. Single fruit weight, soluble solid, fruit shape index and incidence of bitter pit of apple, soil pH, organic matter, elemental content, number of pathogenic Fusarium and changes in fungal community structure were studied. The results showed that the two amendments had good effects on alleviating soil acidification, and Dezhou amendment had the most significant effect. Compared with the control, after treated with Dezhou amendment, single fruit weight of apple increased by 39% on average, fruit shape index reached more than 0.83, soluble solid reached more than 14%, the incidence of bitter pit decreased to less than 1%, soil pH increased by 1.70, soil organic matter increased by 9.00 g/kg on average. In addition, the contents of available copper, available manganese in soil and total copper and total manganese in plant were decreased, the contents of soil exchangeable calcium and total calcium in plant were increased, the number of pathogenic Fusarium was decreased, and the fungal community structure was optimized. In conclusion, the two amendments can effectively relieve soil acidification and promote the growth of apple orchard.
