摘　　要：研究3种问荆属植物,问荆、林问荆、草问荆的生物量。采用样方法,在研究区域内设置1 m×1 m的样方,采挖后称其干重。结果表明,3种问荆属植物的生物量都主要集中在地上且靠近地面的部分,不同种类生物量在垂直方向的具体分布与其植株的分枝情况等生物学特性密切相关。Tne biomass of three species ： Equisetum arvense L. E sylvaticum L and E pratense Ehr was studied. Tne squares of 1 m × 1 m were set and the net weight of Equisetum each square was weighed. The results showed that the over-ground biomass of the three species was mainly concentrated at the part near the ground and vertical distribution of biomass had relationship with the branches of plant.
