应用能流分析和能值分析理论与方法 ,对广东省高州市典型龙眼果园永丰果场在开展绿色食品生产示范试点前后的能流能值进行了分析比较 ,并与广东全省种植业系统及发达国家进行比较 .结果表明 ,试点前后高州市永丰果场的能值产出率分别为 1.0 3和 1.0 9,均比广东省平均水平和发达国家 2 0世纪 90年代初的水平低 ,要提高果园的综合效益 ,应进一步增加可更新资源能值投入 ,提高管理水平和栽培技术 ,建立生态农业
Energy flow analysis and energy analysis theory and method were used to analyze and compare energy flow energy values of Yongfeng fruit farm in typical longan orchards in Gaoshou City of Guangdong Province before and after pilot demonstration of green food production. And developed countries.The results show that the emergy yield of Yongfeng fruit farm in Gaozhou City before and after the experiment is 1.03 and 1.09 respectively, both lower than the average level in Guangdong Province and the developed countries in the early 1990s, To improve the overall efficiency of orchards, renewable energy resources should be further increased investment, improve management and cultivation techniques, the establishment of ecological agriculture
