Biomass energy, recognized for its potential to supplant traditional energy sources, finds a promising alternative in Miscanthus. Particularly, M. lutarioriparius, a species within the Miscanthus genus, stands out as the most suitable for application. This study focuses on the impact of harvest timing on the biomass and combustion quality of M. lutarioriparius in the coastal wetlands of Dongting Lake, Hunan. A comprehensive field experiment was conducted in this area. The findings reveal several key trends: Firstly, the biomass yield of M. lutarioriparius decreased from 18.42 tons per hectare ...
