摘要
阔叶树种在改良林地土壤,提高土壤肥力,改善生态条件等方面有着针叶树种无法比拟的作用。因此,在少林或针、阔叶树种失调的地区,适当发展阔叶树种,十分重要。 营造混交林是发展阔叶树种的一种方式,它具有促进种间互助,充分利用空间,提高生产力和预防病虫害等方面的优点。为了发展优良阔叶用材树种与个别珍贵的针叶树种,自1977年起,选择了马褂木等6个树种与杉木进行混交造林试验,现据生长情况探讨如下。
In order to develop fine broadleaf and precious coaifer commercial woods, Liriodendron chinense (Hemsl.) Sarg, L. tulipifera L., Sassafras tzumu Hemsl., Cinnamomum camphora (L.) Presl, Zelkova schneideriana Hand-Mzt, Fokienia hodginsii (Dunn) Henry et Thomas were selected for mixed plantation experiments with Cunninghamia lanceolata (Lamb.) Hook.. The measurements for 12 year's growth suggested that C. lanceolata could be selected as an associated species in mixed plantation with each experimental species except Z. schneideriana. The stand of C. lanceolata after 10 year's growth could be cut and used as undersized tree sawtimber, and pure crop of undeveloped species left would grow well.
