摘要
为了提高马尾松低产林林业品相及综合效益,笔者对马尾松低产林套种红豆杉和楠木这2种技术模式进行跟踪监测,并从珍稀树种的适应性和效果性、对马尾松生长量的影响、对土壤肥力的影响3个方面进行效益分析。结果表明:马尾松低产林套种红豆杉或楠木模式下的红豆杉及楠木各生长指标均比较良好,这是马尾松低产林改造的一种比较可行方法;套种红豆杉或楠木虽然均能显著促进马尾松的生长,但套种楠木效果更优;马尾松套种红豆杉、楠木模式均能有效改善土壤的物理性质和化学性质,但套种楠木效果更优。
The paper aims to improve the forestry appearance and comprehensive benefit of low yield forest of Pinus massoniana. The author tracked and monitored 2 models of Taxus chinensis and Phoebe interplanted inthe low yield forest of Pinus massoniana, and carried out the benefit analysis through the adaptability andeffectiveness of rare tree species, the influence on the growth of Pinus massoniana and on the soil fertility. Theresults showed that： the growth indexes of Taxus chinensis and Phoebe interplanted in the low yield forest of Pinus massoniana were relatively good, interplanting was a feasible method for the transformation of low yieldforest of Pinus massoniana; and the mode could significantly promote the growth of Pinus massoniana, whilethe interplanting of Phoebe had better effect; both Taxus chinensis and Phoebe interplanted in low yield forest of Pinus massoniana could effectively improve the physical and chemical properties of soil, while theinterplanting of Phoebe had better effect.
