摘　　要：研究不同郁闭度下七指毛桃的株高、地径、叶长与叶宽等生长指标和叶片、枝干及根的生物量干重。结果表明:(1)不同郁闭度对七指毛桃的生长特性及生物量均有不同的影响;(2)郁闭度为0.3时,七指毛桃的株高、叶长、叶宽等生长指标最佳,叶片及根的生物量干重最大,对其生长最有利;(3)郁闭度为0.8时,七指毛桃的株高、叶长、叶宽等生长指标最差,叶片、枝干及根的生物量干重均最小,不利于其生长。The effects of different canopy density on biomass,plant height,ground diameter and theleaf characteristics of F.hirtaVahl.were studied.The results showed that:(1)Different canopy density had different effects on the growth characteristics of F.hirtaVahl;(2)When the canopy density was 0.3,the plant height,leaf length,leaf width,and biomass dry weight of leaves and roots were the most largest,which was beneficial to the growth of F.hirtaVahl.;(3)When the canopy density was 0.8,the plant height,leaf length,leaf width,and biomass dry weight of leaves,branches and roots were the most smallest,which was not conducive to the growth of F.hirtaVahl.
