Abstract：Flyash,phosphate rock and chicken manure were mixed and then were applied into acidic soil in apple orchard to evaluate the effects on acidic soil restoration and yield and quality of apple.The study contained four treatments,i.e.treatment 1:control;treatment 2:3 150 kg flyash+3 150 kg phosphate rock+5 250 kg chicken manure per hectare;treatment 3:2 100 kg flyash+2 100 kg phosphate rock+10 500 kg chicken manure per hectare;treatment 4:1 050 kg flyash+1 050 kg phosphate rock +15 750 kg chicken manure per hectare.The results showed that the soil pH value of treatment 2,3 and 4 increased by 30.57%,27.73% and 24.88% respectively compared to control in the mature period of apple fruit.Under treatment 3,the available nitrogen and potassium contents and microorganism population in soil were the highest compared to the other treatments,but the soil buffering capacity and available phosphorus content were lower than that of treatment 4 and treatment 2,respectively.Although the fruit yield and fruit quality of treatment 3 were the best among the treatments,but no differences were seen between it and treatment 4.It is concluded that flyash,phosphate rock and chicken manure mixed at the level of 2 100,2 100 kg and 10 500 kg per hectare could obviously meliorate acidic soil in apple orchard,and therefore increased fruit yield and quality.
