The results indicated that: (1) The ecological environment of Apple Pleurotus ostreatus system which spacing is 3?m×4?m between the trees planted in 1991 was good for growing. (2) The content of organic matter, readily available N and K in the 0～50?cm soil increased by 45 8%, 31 0% and 39 3% respectively. (3) The content of chlorophyll and the photosynthetic rate of the apple tree leaves increased by 19 7%～23 3%, 5 9%～25 6 % respectively. (4) The yields of Pleurotus ostreatus and its net income was 4 500 1?kg·hm -2 , 609 0?yuan·hm -2 (RMB) respectively.(5) The yields of apple increased by 7 5%.
