摘要
高羊茅能够很好地适应中原地区的土壤及气候条件,表现出生长快、叶量丰富、绿期长的特点,地上生物量累积动态呈Logistic曲线,衰减动态符合y=a+blnx规律,峰值在7月,牧草产量为1.07×105 kg DM/hm2。
Tall fescue(Festuca arundinacea Schreb.)could well adapt to local soil and climate con- ditions of Center China. It showed quicker growth rate,stronger tillering capability and longer green per- iod,and so on. The dynamics of above-ground accumulated biomass was in conformity with the logistic equation,and its attenuation dynamics fitted in with y=a+blnx. The peak value was observed in July,and the productivity per year was about 1.07×105 kg DM/hm2
