对马尾松杜仲混交林的系统调查结果表明,混交林中28年生马尾松平均胸径高于对照纯林10.6%,近两年平均生长量提高7.1%;林分蓄积量增加25.5%;乔木层生物量为112.57吨/公顷,与纯松林接近,但其生产结构显著优于纯林,具有良好的叶和根系的空间配置;改善了林内小气候;增加了林地有机质含量,促进了土壤理化性质的改良,提高了土壤肥力和蓄水保水能力;增强了林分对病虫害的自我抑制能力。马尾松杜仲混交是一种很有前途的针阔混交林。
The results of systematic investigation of Pinus massoniana mixed forest showed that the average DBH of 28-year-old Pinus massoniana forest was higher than that of the control pure forest by 10.6%, the average growth in the last two years increased by 7.1%, the stand volume increased by 25.5% The yield was 112.57 t / ha, which was close to that of pure pine forest, but its production structure was significantly better than that of pure forest, with good spatial configuration of leaves and roots, microclimate in forest, organic matter content of forest land, and improvement of soil physical and chemical properties , Improve soil fertility and water storage capacity; enhance the stand ability of pest and disease inhibition. Masson pine Eucommia mixed is a promising mixed coniferous and broad-leaved forest.
