  • 摘要: 对杉木萌芽林冠下营造细柄阿丁枫后形成的杉阔混交林土壤腐殖质及土壤结构性状研究结果表明，杉阔混交林土壤有机喷和腐殖质含量增加，腐殖质中HA／HF 值和E4值升高，E4 ／E4 值变小，土壤松结合态和紧结合态腐殖质含量及比值增加，土壤庸殖质活化度增强，土壤结构和水分性状得以改善。

     

    Abstract: The soi1 humus and soil structure were observed by planting Slenderstalk ahingia under the canopy of sprout of Chinese fir on mixed stands of Chinese fir and broadleaved tree．The results indicate that the contents of soil organic matter and humus are increased，the HA／HF and E4 value of humus are raised and E4／E6 value is descended，loosely and tightly combined humus contents and its ratio are ascended and the activation of son hunms is strengthened，the soil structure and moisture properties have been improved obviously after the transformed mixed stand of Slenderstalk ahingia．
