摘  要:
Cropping plantation system was the leading industry in the comprehensive ecological system of “Rice Vegetable Pigs Biogas”, in which the photosynthetic efficiency of early and later rice and vegetable was 1 37%, 1 40% and 1 02% respectively.The ratio of output to input energy of organic matter was 2 12 in this system, which was little energy investment in overall, fast energy transformation and high rate of nutrient utilization,with economic, social and ecological benefits.
