Aboveground biomass and water use efficiency of an introduced grass,Panicum virgatum, in the semiarid loess hilly-gully region
黄土丘陵半干旱区引种禾草柳枝稷的生物量与水分利用效率

The eco-adaptability of an introduced grass species is important for its grassland construction in the semiarid conditions on the Loess Plateau. Maximum biomass yield, absolute growth rate (AGR) and relative growth rate (RGR), soil water seasonal dynamics, and water use efficiency (WUE) in switchgrass (Panicum virgatum), an introduced grass species were compared among lowland, terrace land and slope land during 2001~2002 at semiarid loess hilly-gully region in Ansai, Shaanxi province. The aboveground dry bi...
