【目的】研究桉树不同间伐强度处理下各套种树种的生长状况、蓄积量和土壤养分含量,探索适于桉树间伐后套种混交的最佳改培方式。【方法】在广西国有七坡林场,选择不同栽植密度的尾巨桉(DH32-29)与红椎、米老排、火力楠混交,建立4种不同间伐强度的桉树近熟林改培处理(CK、LT、MT、HT),分析不同改培处理中各树种生长状况、土壤理化性质的差异及其之间的相关性。【结果】1)随着桉树配置比例的减小,可促进桉树胸径、树高和单株材积的生长,表现为HT > MT > LT > CK;4个处理中HT和MT桉树胸径、树高、单株材积的生长与LT、CK存在显著差异。2)在CK和LT处理中各套种树种的平均单株材积表现为米老排>火力...

【Objective】To study the growth status, accumulation and soil nutrient content of various interplanting tree species under different thinning intensity treatments of Eucalyptus, and to explore the best cultivation method for interplanting mixed after thinning of Eucalyptus.【Method】In the state-owned Qipo forest farm in Guangxi, select different planting densities of Eucalyptus urophylla×E. grandis DH32-29 mixed with Castanopsis hystrix, Mytilaria laosensis and Michelia macclurei, and establish four kinds of eucalyptus near-mature forests wi...
