Abstract: The ecological orchard is the important way of the development of hilly mountain agricultural. The incongruity between the input system and output system of orchard would cause the ecological unbalance. Interplanting high quality forage grass and establishing the ecological orchard such as “fruit—grass—livestock—(edible fungi)—biogas” would obtain good ecological, economic and social benefits. And the several key links of mountain ecological orchard construction were put forward.
