红壤山地生态果园开发及成效分析

针对红壤山地果园开发中存在生态退化,经济效益低等现状,依据红壤山地农业资源开发整体耦合效应理论,提出了以套种优质牧草为纽带的生态果园开发模式,并详细论述了生态果园生产模式以及果园低改技术、牧草套种技术、草牧结合技术、菌草结合技术以及草沼结合技术等综合配套技术及其实施成效;这一模式不仅可以有效防止水土流失,培肥地力和提高果树产量与品质,同时以牧草为纽带发展牧业、渔业、食用菌业和气能源业,提高综合利用效率,促使丘陵山地农业综合开发的经济、社会、生态效益得以优化发挥。

The Technology and Efficient Analysis of Ecological Orchard in Red Soil Hills

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.
