以梅州地区为例 ,分析了该地区以防治水土流失和开发利用山坡地而兴建小庄园的典型“牧 -沼 -果”生态农业模式的结构及其功能效益。其模式可概括为建立一个以种果为中心 ,结合养猪、养鸡、沼气为纽带 ,综合发展果树种植业、畜牧业的生态种养模式。通过这种模式 ,可减缓农村燃料的短缺 ;提高果树产量和产品品质 ,节约了生产成本 ;改善生态环境和提高了土壤的肥力 ;增加了生物多样性 ,减少了病虫害的危害 ;减少环境污染。研究认为这种模式适合于在南方丘陵山区推广。
Taking Meizhou area as an example, this paper analyzes the structure and functional benefits of a typical “animal husbandry - marsh - fruit” eco - agricultural model in this area to prevent and control soil and water loss and to develop and utilize hillsides. The model can be summarized as: to establish a seedling-centered, combined with pigs, chickens, biogas as a link, the integrated development of fruit tree planting, animal husbandry, ecological planting and breeding mode. Through this model, the shortage of fuel in rural areas can be alleviated; the output of fruit trees and product quality can be improved; the production cost can be saved; the ecological environment can be improved; the fertility of soil can be increased; the biodiversity can be increased, the harm of pests and diseases can be reduced, and the environmental pollution can be reduced. Studies suggest that this model is suitable for promotion in the hilly mountains of the South.
