研究了m的组成、纤维素降解性和生化甲烷势（BMP）。sinensis, M。floridulus,芒草×giganteusandM。在不同的生长/采收时期，对黄颡鱼进行了调查。四种植物的成分含量变化不大。同时，BMP值也发生了巨大的变化。生长60 d时，bmp值为247.1 ~ 266.5 ml g−1VS。随着生长时间的延长，bmp降低了11% ~ 35%。各树种BMP与纤维素降解率呈显著正相关，相关系数（R2）在0.8055 ~ 0.9925之间。这表明，除了生物量产量，在选择合适的收获时间时考虑纤维素的可降解性是合理的，特别是在热带和亚热带地区，芒草可以在一年内收获两次或更多。
The composition, cellulose degradability and biochemical methane potential (BMP) ofM. sinensis,M. floridulus,Miscanthus×giganteusandM. lutarioripariuswere investigated concomitantly at different growth/harvest times during their growing season. For all the four species, there was only a slight change in the compositional content. Meanwhile there was a huge change in the BMP values. At the growth time of 60 days the BMPs ranged from 247.1 to 266.5 ml g−1VS. As growth time was prolonged, the BMPs decreased by 11–35%. For each species, the BMP was positively correlated to the cellulose degradability with the correlation coefficients (R2) ranging from 0.8055 to 0.9925. This suggests that besides the biomass yield, it is justifiable to consider cellulose degradability when selecting the suitable harvest time for biofuels production fromMiscanthus, especially in tropical and subtropical regions whereMiscanthuscan be harvested twice or more within a year.
