Abstract

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.

Key words: Agro forestry system, Eco agricultural model, Energy flow, Rubber tea chicken
