| 摘要: |
| 黑格、枫香树和荷木是广西重要的乡土阔叶造林树种,为评估其纯林及其在马尾松林下混交的造林效果,该研究对这3种阔叶树的1年生容器苗进行纯林和马尾松林下混交造林,3年后调查分析其树干、树冠生长和树干干形的差异,并采用层次分析法对其生长情况进行综合评价。结果表明:(1)纯林模式下黑格、枫香树的树高和胸径较大,树干生长较好且多干率较低,而林下混交模式下荷木的树高和胸径较大,树干生长较好。(2)纯林和马尾松林下混交模式下黑格的冠幅、枝下高和自然整枝能力均较大,冠径比相对较小,其树冠生长较好; 纯林模式下枫香树的分杈率、高径比较小,树干干形较好,马尾松林下混交模式下荷木的高径比、倒伏率较小,树干干形较好。(3)生长情况综合评价结果为黑格纯林>枫香树纯林>林下荷木>林下黑格>荷木纯林>林下枫香树。因此,纯林模式下生长情况最好的为黑格,马尾松林下混交模式下生长情况最好的为荷木。该研究结果为黑格、枫香树和荷木在广西区域内的栽培技术研究提供了科学依据。 |

| Abstract: |
| Albizia odoratissima, Liquidambar formosana, and Schima superba are key native broad-leaved tree species for afforestation in Guangxi, China. To assess the afforestation performance of these species in both pure stands and understory mixed stands with Pinus massoniana, a field experiment was conducted using one-year-old container-grown seedlings of the three broad-leaved species. Two planting configurations were established: pure stands of each species, and mixed stands where each species was interplanted under Pinus massoniana canopies. After three years of growth, differences in trunk growth, crown development, and stem form among the treatments were investigated and analyzed. Additionally, the analytic hierarchy process(AHP)was employed to conduct a comprehensive evaluation of the overall growth performance of each species under different configurations. The results were as follows:(1)In the pure plantation, Albizia odoratissima and Liquidambar formosana exhibited greater tree height and diameter at breast height(DBH), with better trunk growth and lower ratio of multtiple tree trunks. By contrast, Schima superba showed larger tree height and DBH as well as superior trunk growth under the understory mixed-planting model.(2)In both pure plantations and understory interplanting under Pinus massoniana plantations, Albizia odoratissima had larger crown diamrter, higher height of clear bole and better natural pruning capacity, together with a relatively small crown-diameter ratio contributing to favorable crown growth. Liquidambar formosana under the purep lantation model possessed low branching rate and height-diameter ratio, presenting good trunk form. Schima superba grown under the Pinus massoniana understory mixed-planting model had low height-diameter ratio and lodging rate, and its trunk form was desirable.(3)The comprehensive AHP evaluation of growth performance ranked the treatments in the following order: Albizia odoratissima(pure forests)> Liquidambar formosana(pure forests)> Schima superba(understory)> Albizia odoratissima (understory)> Schima superba(pure forests)> Liquidambar formosana(understory). Consequently, Albizia odoratissima is identified as the top-performing species in pure stands, while Schima superba is the most suitable for understory mixed planting with Pinus massoniana. This study provides a scientific basis and theoretical reference for optimizing the cultivation techniques of Albizia odoratissima, Liquidambar formosana, and Schima superba in the Guangxi region. |
