马尾松细根研究进展

根系是植物长期适应陆地条件而形成的一个重要的地下器官,在整个生态系统中扮演者重要的角色。细根作为根系系统中最重要部分,对森林生态系统碳平衡和养分循环具有重要作用。马尾松是我国速生特有种,集经济价值和生态价值为一体。文中综述了马尾松细根生物量、周转和寿命的研究进展,并对今后的研究提出展望,以期为我国树木根系生态学研究提供参考。

A Review of Fine-root of Pinus massoniana

Root system is an important underground organ of plants, which has been formed when plants have been adapted to land conditions for a long time, and the system plays significant roles in the whole ecosystems. Fine roots, as the most important part of root system, has a great effect on carbon balance and nutrient recycling in forest ecosystem. Pinus massoniana is a fast-growing endemic to China, and integrates economic and ecological values into one. We summarized the biomass, turnover and lifespan of the fine-root of P. massoniana. Then, we put forward the direction of future research, in order to provide a reference for tree root ecology in China.
