Abstract: 24 field plots including 9 rice-based cropping systems from Taihu alluvial plain were selected and investigated for the grain yield, biomass output, and the input of energy, fertilizer and labour. Then, the utilization rate of solareradiation and the conversion of input energy to output bioeuergy in various cropping systems were compared and evaluated. The energy transferring in pig production with different feeds was conducted as well.
