【Abstract】 A case study for the structure and effects of "pig-biogas-tea" eco-agriculture was carded out in Fenghuang town,Chao’an County, Guangdong Province. In such eco-agricuiture, animal husbandry, biogas production and tea farming were combined and developed into a cycling ecosystem. The investigation and analysis results showed that this farming system could decrease the inputs and costs, and increase the quality of tea. Meanwhile, the application of wastes of biogas production could also reduce and replace the use of chemical fertilizers and pesticide, by doing so, it could improve soil fertility and environment quality. It was indicated that this kind of eco-agriculture model had good ecological, economical and social benefits, so it would be extended in the hilly areas of south China.更多还原
