闽东山地火力楠人工林生长特性及其对土壤肥力的影响

闽东山地火力楠人工林生长及其对土壤肥力影响的研究结果表明,火力楠适应性强、生长快,与杉木混交,因发挥了种间关系效益及辅佐功能,林分生产力大大提高。此外,火力楠能明显改善土壤理化性状,是闽东沿海山地土壤改良、低产林改造及防治杉木多代连栽地力衰退的理想树种,可作为用材林定向培育。但在经营过程中,应根据林分生长发育特性和林木分化情况,实施动态抚育间伐技术,以充分发挥火力楠的生产力和改土效果。

Study on Growth Characteristics of Michelia macclurei's Stands and Impacting on Soil Fertility in Fujian-east Mountainous-region

The study results showed that Michelia macclurei adaptability was strong and its growth was rapidness.Mixing Cunninghamia lanceolata,the mixed stands productivity are increased evidently,because of exerting the interspecific relation and function of its assistant.Furthermore,Michelia macclurei improving soil was evident,it was an ideal tree in soil improvenment and low yield stands rebuild or prevention and cure terra-fertility recessionary.But on the process of management,the mixed stand need to improve interspecific relation further and adjust stand structure through proper thinning,according to forest growth and forest differentiation.
