The Economic and ecological effects of the Apple Pleurotus ostreatus system on ecology, physiology and yield in the hilly land of Taihang Mountain were studied, comparing with the pure apple tree stand(CK). 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%. (6) The total net income of the system increased by 7 025?yuan·hm -2 (RMB). 展开更多
