carex monostachya/减肥

With net sack and coring methods, this paper analysed the seasonal dynamics of litter and under-ground biomass of Carex lasiocarpa population in Sanjiang Plain wetland. The standing litter showed exponential seasonal dynamics. The decomposition rate of litter was indicated by the rate of its weight

The decomposition and microbial colonization of Carex leaf litter were examined in an arctic lake in Alaska during the summer of 1978. Dried leaf segments in screen bags were placed at various locations and depths for 13 and 26 days. Weight loss varied from 24.15 to 33.56% and from 27.69 to 65.01%
