Abstract: Ecological orchard mode combined with intercropping fine grass was brought forward on the basis of the theory of coupling effect in order to prevent from ecological degradation of red soil hills in the paper, and the production mode of ecological orchard, the technologies of reconstructing of orchard, intercropping grasses, combining grass with herd, edible fungus and firedamp and their effects were discussed in detail. The mode not only prevented from water and soil loss, improved soil quality and advanced the output and quality of fruit trees in effect but also be propitious to develop herd, fishery, edible fungus and energy sources of firedamp, which should increase the efficiency of comprehensive utilization and make the economical, social and ecological benefits of comprehensive development of hilly agriculture optimize and exert.
