摘要

不同林种的种植间距会对增加或减少土壤中的化学元素含量产生不同的作用,从而影响土壤的成分和质量。为特定林种确定适当的种植间距非常重要,不仅能优化生产力,还能为退化土壤的恢复提供决策依据。这项工作的目的是评估以不同间距种植 Tachigali vulgaris(约七年半树龄)的土壤在化学特性方面发生的变化。这项工作在 Dom Eliseu(宾夕法尼亚州)市的 Fazenda Gênesis 进行。在 30 米 x 50 米的地块中,在四个深度采集了土壤样本,每个间距有四个重复。每个小区随机选取 16 个土壤采集点。土壤样本被送往 Embrapa Amazônia Oriental 实验室进行化学分析。PCA 结果显示,在所有深度,铝与其他土壤属性呈负相关。双向方差分析图(p < 0.05)表明,4 米 x 3 米的间距在大多数深度上对土壤有益的化学属性值最高,与其他两种间距中的至少一种相比,铝的值较低,因此这种间距最适合恢复退化的地区/土壤。

Efeito de diferentes espaçamentos de plantio de Tachigali vulgaris L.G.Silva & H.C.Lima na fertilidade do solo
Different planting spacings of forest species can act differently in increasing or decreasing the levels of chemical elements in the soil, which affects its composition and quality. Defining adequate planting spacing for a given forest species is important, not only to optimize productivity, but also for decision-making in the recovery of degraded soils. This work aimed to evaluate the changes occurring in the chemical properties of a soil planted with Tachigali vulgaris at different spacings, approximately seven and a half years old. The work was carried out at Fazenda Gênesis, in the municipality of Dom Eliseu (PA). Soil samples were collected at four depths in 30 m x 50 m plots with four replications for each spacing. Sixteen soil collection points were randomly selected for each plot. The soil samples were sent to the Embrapa Amazônia Oriental laboratory where chemical analyzes were carried out. The PCA results showed that Al was negatively correlated with other soil attributes at all depths. The two-way ANOVA graphs (p < 0.05) demonstrated that the 4 m x 3 m spacing had the highest values in the chemical attributes beneficial to the soil at most depths in relation to at least one of the other two spacings studied, and lower values for Al, making this spacing the most suitable for recovering degraded areas/soils.

期刊介绍: Scientia Forestalis is a scientific publication of the IPEF – Institute of Forest Research and Studies, founded in 1968, as a nonprofit institution, in agreement with the LCF – Department of Forest Sciences of the ESALQ – Luiz de Queiroz College of Agriculture of the USP – São Paulo University. Scientia Forestalis, affiliated to the ABEC – Brazilian Association of Scientific Publishers, publishes four issues per year of original papers related to the several fields of the Forest Sciences. The Editorial Board is composed by the Editor, the Scientific Editors (evaluating the manuscript), and the Associated Editors (helping on the decision of acceptation or not of the manuscript, analyzed by the Peer-Reviewers.
