%X The effects of Apple-Aadsurgens system on ecology,physiology and yield,and land equivalent ration in the hilly land of Taihang Mountain are studied.The results show that the contents of organic matter,available N in the 0~ 50cm soil increase by 30% and 32% compared with the pure apple tree stand (CK1) respectively,and the content of available K decreases by 2.1 % ; the content of chlorophyll and the photosynthetic rate of the apple tree leaves and apple yield increase by 24.3%,28% and 15.5% compared with CK1 respectively; the dried matter yield,the content of coarse protein,the coarse adipose and soluble sugar of A.adsurgens increase by 18.5 %,36.4%,27.4% and 11.8% compared with the sole A.adsurgens system (CKII) respectively,the land equivalent ration (LER) of this system is 1.65.
