Exploitation and utilization of Miscanthus & Triarrhena
摘要
In taxonomy there is a new species of MiscanthusTriarrhena denominated in1989,which is an endmic and native grass in China:Triarrhena lutarioriparia L.Liu,sp.nov.The growth rate is5～7meter per year which can produce22.5～30tons of dried-stem per ha per year,being a high biomass plant.As a radical resource,it has been used as a crucial material for paper-making industry.The stems contain50%(43%～65%)of the fibrous cells,with average length each being3mm(2～6.8mm),the maximum,6.8mm.This grass have been proven by scientific approaches as potential crops of C 4 -Plants.In Eu-ro pean countries like Germany and England,MiscanthusTriarrhena is regarded as fuel crops in the future to generate electricity for power stations,i.e.,an important renewable plant re-sources.The research reveals that MiscanthusTriarrhena is a valuable plant in environmental protection which can balance CO 2 /O 2 ,reduce soil N 2 O and mitigate greenhouse effects in atmo-sphere.
