Abstract

Background: The production of Coffea arabica L. in most of the world is carried out under agroforestry systems, whose associated tree assembly provides microclimatic conditions and other benefits such as product diversification, biodiversity conservation, carbon sequestration, increased soil fertility, and pest and disease control. Objective: to characterize the tree component and its classification by use and value in a shade-grown coffee agroforestry system in Siltepec, Chiapas. Methodology: Five clusters were established, each with three randomly distributed sampling units, with a total of 15 sampling units with an area of 400 m2. An inventory of the trees was carried out, classifying the associated species. Structural parameters (height, normal diameter, densities, basal area) and importance value index were estimated. Results: 30 tree species representing 19 botanical families were found; the Fabaceae Inga flexuosa, Inga laurina, Inga paterno, Dyphisa americana were the most important. The height of the tree component reached 27 m, with a more significant number of trees for class 2 at 7 m (1743 ind. ha-1 [78.73%]). The diameter class from 2.5 to 10 cm (532 trees) had the highest number of individuals. The average density corresponds to 1155 ind. ha-1, Inga flexuosa (chalum) the tree species with the most significant presence (510 ind. ha-1) with an importance value of 60.13%. The basal area obtained corresponds to 119.5 m2 ha-1, Inga laurina (caspirol) has the most significant spatial distribution (54.02 m2 ha-1). Implications: The study allows dimensioning of the importance of tree associations that occur within an agroforestry system of Coffea arabica L. in soh a way that those parameters and the composition of species can be determinants of the productive capacity of each plot. The study considers the benefits of the tree component in coffee production and contributing goods and services that give greater sustainability to the agroecosystem. Conclusions: There was a high tree density, with the Fabaceae family and particularly the Inga genus being the most important in the studied area, which allows excellent benefits such as the contribution of Nitrogen, nutrient recycling, soil fertility and decreased erosion in the coffee plantations

与墨西哥恰帕斯Siltepec的阿拉伯咖啡农林系统相关的树木组合

背景：世界上大多数地区的小粒咖啡生产都是在农林系统下进行的，其相关的树木组合提供了小气候条件和其他好处，如产品多样化、生物多样性保护、碳封存、提高土壤肥力以及病虫害控制。目的：通过在恰帕斯州锡特佩克的荫蔽咖啡农林系统中的使用和价值来表征树木成分及其分类。方法：建立了五个集群，每个集群有三个随机分布的采样单元，共有15个采样单元，面积为400m2。对树木进行了清查，对相关物种进行了分类。估计了结构参数（高度、正常直径、密度、基底面积）和重要值指数。结果：共发现19个植物科30种；其中以蚕豆科的弯叶Inga、月桂Inga、家长Inga、美洲Dyphisa最为重要。树木组成部分的高度达到27米，7米处的2类树木数量更为显著（1743 ind.ha-1[78.73%]）。直径为2.5至10厘米的类别（532棵树）的个体数量最多。平均密度对应于1155 ind.ha-1，弯曲银杉（chalum）是存在最显著的树种（510 ind.ha-1），重要性值为60.13%。获得的基底面积对应于119.5 m2 ha-1，月桂银杉（caspirol）具有最显著的空间分布（54.02 m2 ha-1）。含义：该研究允许确定小粒咖啡农林系统中发生的树木关联的重要性，从而使这些参数和物种组成可以成为每个地块生产能力的决定因素。该研究考虑了树木成分在咖啡生产中的好处，以及为农业生态系统提供更大可持续性的商品和服务。结论：咖啡种植园的树木密度很高，Fabaceae科，尤其是Inga属是研究区域中最重要的一个属，这使得咖啡种植园具有良好的效益，如氮的贡献、养分循环、土壤肥力和减少侵蚀

期刊介绍： The journal is an international peer-reviewed publication devoted to disseminate original information contributing to the understanding and development of agroecosystems in tropical and subtropical areas. The Journal recognizes the multidisciplinary nature of its scope and encourages the submission of original manuscripts from all of the disciplines involved in this area. Original contributions are welcomed in relation to the study of particular components of the agroecosystems (i.e. plant, animal, soil) as well as the resulting interactions and their relationship/impact on society and environment. The journal does not received manuscripts based solely on economic acpects o food technology.
