A Review of Silviculture for Solid-wood Production from Eucalyptus Plantations

培育大径材用于实木加工是桉树人工林发展的趋势,但桉树人工林大径级原木的培育尚缺乏经验。本文综述了国内外在桉树大径材树种选择、初植密度控制、间伐、修枝和施肥管理方面的现状及其对大径材生长和材性的影响,以期为桉树资源高效利用及大径材人工林的可持续发展提供借鉴和依据。

The area of plantations in China dedicated to production of larger diameter Eucalyptus logs to supply higher value solid-wood products has expanded over recent years.However,the knowledge of appropriate silvicultural management for such plantations is lacking.To provide a basis for efficient utilization of Eucalyptus resources and sustainable development of plantations targeting larger diameter log production,we present a review of the silvicultural treatments and regimes used for management of such plantations around the world,including:tree species selection,stand density,thinning,pruning and fertilization.The effects of the silvicultural management on tree growth and wood quality were also summarized.
