Efficiency of Forage Cultivation and Utilization and Analysis on Its Energy-saving Function in Hilly Area of South China

17 cultivars of forage grass have been introduced and cultured in hilly area of Fuzhou.Through the utilizing manners of rotation grazing of goalt,grass-eating fish raising,growth of small-size livestock and poulstry,cultivation of edible fungi and biogas fermentation,the energy-saving efficiency of forage grasses in hilly area was studied.The results showed that the average solar energy-utilizing rates of forage grasses was 1.24%.After integrating with the energy-recycling practices for re-utilizing the residuals from production system,the energy-transforming rate of forage grass in trail area reached 2.02%.
