The ecological effect and economic return of t he P. com m unis multistage utility technique was studied . P. com m unis residue was firstly used to culture mushroom ,and t hen mushroom residue was used as medium of vegetable cultivation ,and finally t he medium residue wit h vegetable root was applied to farmland as organic matter . The result showed t hat t he assis tant energy efficient is 8. 1 % in t he mushroom culture and 8. 4 % in t he vegetable culture . N transformation efficiency is about 40 %bot h in mushroom and vegetable culture . The yield of bot h mushroom and vegetable wit h P. com m unis residue as medium are equal to t he yield wit h conventional medium culture . For t he cost of P . com m unis residue is much less t han conventional medium ,t he economic return is much higher as well . Key words : Phrag m ites com m unis residue ,mushroom residue ,multistage utilization . 关 　键 　词 :芦苇末 ,菇渣 ,多级利用 中图分类号 :S3 17 ; S64 1. 2 　　　文献标识码 :A 　　　文章编号 :1000 - 4890 (2002) 0 1 - 0035 - 03 (
