摘要: 以海南省文昌市典型的胶茶鸡农林复合系统模式为研究对象,分析了我国热带地区单作胶园、胶茶间作园及养鸡胶园的能流路径、能量输入、输出结构及能流转化效率。结果表明,单作、间作及养鸡胶园的光能利用率逐渐提高,其能量产投比为1.50、1.88、0.20;有机能投入比为0.138、0.119、0.977,养鸡胶园最高;无机能投入比分别为0.862、0.881、0.023;养鸡胶园中人工辅助能投入比相对减少,其产出能最大.

Abstract: The comparative analysies on the energy flow path, its input and output structure, and conversion efficiency of single rubber culture(R), rubber tea inter cropping(RT) and rubber tea chicken(RTC) gardens in Wenchang City, Hainan Province show that the utilization efficiency of solar energy increased gradually in the order of above mentioned three kinds of gardens. Their total energy output/input ratios were 1.50, 1.88 and 0.20, the organic energy input/total input ratios were 0.138, 0.119 and 0.997, and the inorganic energy input/total input ratios were 0.862, 0.881 and 0.023, respectively. In RTCsystem, the artificial subsidiary energy input decreased, and energy output increased.
