摘要: 笔者对杉木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、对杉木生长量的影响、对土壤肥力的影响3个方面进行效益分析。结果表明:杉木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,这是杉木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杉木的生长,但套种楠木效果更优;杉木套种红豆杉、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。

Abstract: The author tracks and monitors the Chinese fir low yield forest interplanting chinese yew or nanmu these 2 kinds of techniques , and analysis the benefit of the adaptability and effectiveness of rare and endangered tree species,the influence on the growth of chinese fir,the influence on the soil fertility.the results show that :the growth indexes of chinese yew or nanmu in the low yield forest of chinese fir were relatively good, and this was a feasible method for the transformation of low-yield forest in fir wood. It can significantly promote the growth of Chinese fir trees, but interplant nanmu has better effect; Both the chinese yew and nanmu model can effectively improve the physical and chemical properties of the soil, but interplant nanmu has better effect.
