摘要
以鄱阳湖南矶山湿地灰化苔草为对象,研究了其生物量、株高、鞘高等生长指标,分析了其季节生长动态。研究结果表明:灰化苔草各指标的季节生长动态基本一致,皆呈单峰型曲线;灰化苔草的地下生物量>地上总生物量,各构件生物量关系为根>茎>叶;灰化苔草种群的地上生物量与株高、鞘高呈线性函数关系,利用鞘高和株高可较好地预测灰化苔草种群地上生物量。
The seasonal growing dynamic of Carex cinerascens in Nanji Mountain wetland of Poyang Lake was investigated by periodical measuring the growth indices, including the biomass, plant length and sheath height. The results showed that the seasonal growing dynamic of the above growth indices were similar, and all appeared monopeaks curve. The underground biomass of C. cinerascens was far higher than the aboveground biomass, and the root biomass of C. cinerascens was higher than the stem biomass and the leaves biomass. The fitting curves between aboveground biomass and plant length and sheath height of C. cinerascens were liner forms, and the population aboveground biomass could be accurately predicted by measuring the sheath height or plant length of C. cinerascens.
