摘要
栎（quercus robur L.）和红栎（Q. rubra L.）（分别为有花序和北方红栎）生产高价值木材。混合种植吸引了人们的注意，因为它们提供了几个好处；然而，它们在非原生栖息地的试验中很少被包括在内。目的评价纯混交林和混交林（含伴生树种）下黑栎和黑栎的生长状况、健康状况和木材品质。方法对在智利南部建立的黑桫椤和红桫椤纯林和混交林进行了23年的生长监测。混交林由一个主要的森林物种群（麻豆）组成。3个混交林，包括4个主要树种和1个伴生树种（Alnus glutinosa L.、Gevuina avellana Mol.或Embothrium coccineum j.r.f forst）。, G.Forst)。在23岁时测量木材质量变量和健康状况。生长变量采用线性混合模型分析，质量木材变量采用χ2检验。结果两种树种在树木生长、活力和植物检疫方面均表现良好。在不同的处理中，在23岁时，红毛柏的树形比红毛柏大。在纯人工林中，红毛柏最初的生长速度高于红毛柏，但从15岁开始，红毛柏的生长速度超过红毛柏。主要种群和含球尾木群的林分蓄积量均高于纯人工林。不同人工林类型的红毛柏树高没有差异。与粘棉栎的关联降低了两种栎树的生长，与黄皮栎的关联对红栎的生长影响为中性，对红栎的生长影响为负（降低了栎的高度和体积）。结果表明，主要物种群落的每公顷体积高于纯刺柏人工林。结论两种植物在纯人工林和混作人工林均具有生产潜力。可以推荐混合人工林作为纯人工林的替代选择，以生产优质木材。根据特定的立地条件充分选择主要树种和伴生树种对生产性人工林的成功至关重要。本文章由计算机程序翻译，如有差异，请以英文原文为准。
Performance of Quercus rubra and Quercus robur in pure and mixed-species plantations
Context
Quercus robur L. and Q. rubra L. (pedunculate and Northern red oak, respectively) produce high-value timber. Mixed plantations are attracting attention because they provide several benefits; however, they have been included in few trials in non-native habitats.
Aims
This study assessed growth, health, and timber quality of Quercur robur and Q. rubra trees growing in pure and mixed plantations including companion tree species.
Methods
Growth was measured periodically in Q. robur and Q. rubra pure and mixed plantations established in southern Chile for 23 years. Mixed plantations consisted of a main forest species association (Castanea sativa Mill., Quercus rubra, Q. robur and Prunus avium L.) and three mixed plantations including the four main forest species plus one companion tree species (Alnus glutinosa L., Gevuina avellana Mol. or Embothrium coccineum J.R.Forst. & G.Forst.). Timber quality variables and health status were measured at age 23. Growth variables were analyzed using linear mixed models and quality timber variables, using a χ2 test.
Results
Both species exhibited a positive performance in tree growth, vigor, and phytosanitary status. Across treatments, Q. rubra presented bigger trees than Q. robur at age 23. In the pure plantation, Q. robur initially showed higher growth rates than Q. rubra, but from age 15, the latter outperformed the former. Q. robur tree volume was higher in the main species association and the one including E. coccineum than in the pure plantation. Q. rubra tree size showed no differences between plantation types. The association with A. glutinosa reduced both oak species growth, and the one with Gevuina avellana had a neutral effect on Q. rubra and a negative effect on Q. robur (reduced height and volume). Finally, the main species association showed higher volume per hectare than the pure Q. robur plantation.
Conclusion
Both species showed productive potential in pure and mixed plantations. Mixed plantations can be recommended as an alternative to pure plantations to produce quality timber. Adequately selecting the main and companion species based on site-specific conditions is crucial for the success of productive plantations.

期刊介绍：
Forest Ecology and Management publishes scientific articles linking forest ecology with forest management, focusing on the application of biological, ecological and social knowledge to the management and conservation of plantations and natural forests. The scope of the journal includes all forest ecosystems of the world.
A peer-review process ensures the quality and international interest of the manuscripts accepted for publication. The journal encourages communication between scientists in disparate fields who share a common interest in ecology and forest management, bridging the gap between research workers and forest managers.
We encourage submission of papers that will have the strongest interest and value to the Journal''s international readership. Some key features of papers with strong interest include:
1. Clear connections between the ecology and management of forests;
2. Novel ideas or approaches to important challenges in forest ecology and management;
3. Studies that address a population of interest beyond the scale of single research sites, Three key points in the design of forest experiments, Forest Ecology and Management 255 (2008) 2022-2023);
4. Review Articles on timely, important topics. Authors are welcome to contact one of the editors to discuss the suitability of a potential review manuscript.
The Journal encourages proposals for special issues examining important areas of forest ecology and management. Potential guest editors should contact any of the Editors to begin discussions about topics, potential papers, and other details.
