In response to the challenge of harmonizing agricultural production with sustainable environmental management, setting up of agroforestry systems (AFSs) is an appealing alternative that combines crops and wood production with ecosystem services. In this context, Schizolobium parahyba var. amazonicum Huber × Ducke (paricá) has shown good silvicultural performance in AFSs. Nevertheless, the properties of its wood when grown in AFSs are not widely reported in the literature. The present study aimed to characterize paricá wood regarding its technological characteristics and industrial applications. Wood was obtained from a multi-stratified AFS in midwestern Rondônia state, northern Brazil. The AFS is composed of perennial crops and forest species cultivated in double rows with spacing of 5.0 m × 2.5 m. Experimental results showed paricá wood had low extractives content and density along with good dimensional stability. However, the wood’s mechanical performance was similar to that observed in material from pure plantations and pristine forests. Specific strength was similar to wood species with higher basic densities. Paricá wood reached the minimum requirements for structural uses and had suitable characteristics to be employed to produce engineered wood panels.

从副生裂殖酵母中鉴定木材。亚马逊雨林中建立的多层农林业系统的马祖尼克·胡伯×鸭树

为了应对使农业生产与可持续环境管理相协调的挑战,建立农林业系统是一种有吸引力的选择,它将农作物和木材生产与生态系统服务相结合。在这种情况下,裂殖酵母属变种。亚马逊Huber×Ducke(paricá)在AFS中表现出良好的造林性能。然而,在AFS中生长时其木材的特性在文献中并未得到广泛报道。本研究旨在从技术特性和工业应用方面对仿木进行表征。木材来自巴西北部朗多尼亚州中西部的多层AFS。AFS由双季种植的多年生作物和森林物种组成,间距为5.0 m×2.5 m。实验结果表明,巴利克木具有较低的提取物含量和密度以及良好的尺寸稳定性。但是,木材的机械性能与纯人工林和原始森林的材料所观察到的相似。比强度类似于具有较高基本密度的木材。
