| Abstract: | Through 3 years' experiment,the adaptation and productivity of Festuca arundinaceawas studied in this paper.The results indicated that,Festuca arundinacea could well adaptto local soil and climate conditions.It had strong tillering capability,long green period and grew fast.The dynamics f accumulated above ground biomass was in conformity with thelogistic equation.Its attenuation dynamics fitted in with y=a+blnx.Peak value was in July.Annual productivity was about 9868.42 DM kg/hm2. |
