In biomass allocation, it partials to belowground mass when resource availability is low, otherwise it invests in overground mass.
生物量分配在资源可利用水平低时，偏向于地下部分，否则资源更多的投资给地上部分；
The biomass of rhizome, adventitious root, and belowground part were maximal under dry-wet alternate condition at both growth stages.
在生长旺盛期和末期，干湿交替处理下毛苔草根茎、不定根及地下总生物量均最高；
There was positive correlation between aboveground biomass and heating field, while there was not significant relationship between belowground biomass and heating field.
