摘　　要：探讨了华安县湖林乡吉土村杉木马尾松混交林和火力楠林下不同坡位和郁闭度对阳春砂仁生物性状的影响。结果表明:阳春砂仁在马尾松混交林和火力楠林林种植时,坡位之间的生物性状在株数、叶片数量、花序数量、单果重、产量存在显著差异,下坡位更适宜阳春砂仁种植;不同郁闭度之间的生物性状在株数、叶片数量、花序数量、单果重、产量存在显著差异,郁闭度为0.5~0.6时获得更好的生物性状。The effects of slope positions and canopy density on the biological characteristics of Amomumvillosumin mixed forest of Cunninghamialanceolata and Pinusmassoniana or in Phoebe macclurei were investigated in Jitu Village,Hulin Town,Hua'an County.The results showed that when Amomumvillosum was planted in Pinusmassoniana mixed forest and Phoebe macclurei forest,there were significant influences of slope positions and canopy density on the plant number,leaf numbers,inflorescence numbers,single fruit weight and overall yield.Biological characteristics of Amomumvillosum are better when downhill slope and canopy density is 0.5~0.6.
