发酵基料-蚯蚓-鳝鱼食物链物流与能流转化效率的研究

对废弃物食物链发酵基料 蚯蚓 鳝鱼的物质流和能量流转化效率研究结果表明 ,该食物链经济产品物质、能量转化效率较低 ,生物量转化效率为 0 .9% ,N、P转化效率分别为 2 .1 %和 0 .6 % ,能量转化效率为 1 .0 % ,其经济和生态效益明显

Study on the transforming efficiency of material flowing and energy flowing in the foud chain of fermented basic staple-earthworm-mud ee1

The transforming efficiency of material flowing and energy flowing in the waste material foodchain of fermented basic staple earthworm mud eel are studied in this paper. The results show that the foodchain has lower material and energy transforming efficiency of economic products. The biomass, N, P and energy transforming efficiency are 0.9%, 2.1%, 0.6% and 1.0% respectively, but it has distinctive economic and ecologic benefits.
