中文摘要：

研究了蕨麻在不同种植密度条件下对其地下块根的影响。结果表明：不同种植密度对蕨麻地下块根的形成膨大影响较大,高密度处理下对蕨麻单株块根的数量、块根重量及块根直径（即膨大率）均显著小于低密度处理。

英文摘要：

Root tuber growth of P.anserinain different planting density were studied.The results indicated that obvious effects existed on occurrence and expansion of root tuber of Potentillaa nserinain different planting density.In the higher planting density the number,weight and diameter of root tuber per plant,all of those were significant less than the lower planting density.
