“猪—沼—果(林)”三位一体的生态经营模式是指采用果、林、畜相结合,以生草栽培等多种方式进行山地小流域综合开发建设。研究表明:该模式以生草等提供更多的饲料来源,并以其改善果园生态环境,以沼液、沼渣、沼气综合节支增收,改良土壤、果品等,以养猪、种果直接创收,可产生好的生态、经济和社会效益,推进农村山地综合开发可持续发展。 “Pig - Marsh - fruit (forest) ” Trinity of the ecological business model is the use of fruit, forest, animal husbandry combined with grass-planting and other means of a comprehensive development and construction of small mountainous watershed. The research shows that the model provides more feed sources such as raw grass and improves the ecological environment of the orchards. The comprehensive utilization of biogas slurry, biogas residue and biogas can increase income, improve soil and fruits, and raise pigs directly. Income, can produce good ecological, economic and social benefits, promote the comprehensive development of mountainous areas of sustainable development.
