摘要

导言:热带干燥森林(TDF)中分散的树木将大量的凋落叶沉积到牧场土壤中。目的:研究旱季散种针叶水飞莲的凋落物产量。和白菖蒲。& Cham)。牧场上的西格勒和艾宾格树。材料与方法:在10-ha的草地上，每个树种10株分散分布，在旱季(11 - 5月)收集凋落物，并进行分类。测定凋落叶生物量、氮(N)、木质素(L)含量及木质素-氮(L/N)比。利用双逻辑模型对年周期的凋落叶进行了建模。所有变量的平均值在物种之间使用t检验进行比较。结果与讨论:种间凋落物、氮、木质素含量相近。结论:草地散落树木凋落叶的数量和质量有利于采用农林业系统，包括TDF的原生树种

Litterfall from tropical dry forest trees scattered in pastures

Introduction: Scattered trees from tropical dry forests (TDF) deposit significant amounts of leaf litter into pasture soils. Objective: To estimate the litterfall production during the dry season by scattered Lysiloma acapulcense (Kunth) Benth. and Vachellia pennatula (Schltdl. & Cham.) Seigler & Ebinger trees in pastures. Materials and methods: Ten scattered trees of each species were selected from a 10-ha pasture, and litter was collected during the dry season (November to May) and sorted into fractions. Leaf litter biomass, nitrogen (N) and lignin (L) content, and the lignin-nitrogen (L/N) ratio were assessed. Leaf litterfall was modelled over an annual cycle using a double logistic model. Means from all variables were compared between species using a t-test. Results and discussion: Litter, nitrogen and lignin content were similar between species. However, the L/N ratio was significantly higher (P Conclusion: The quantity and quality of leaf litter that scattered trees deposit in a pasture encourages the adoption of agroforestry systems, including tree species native to TDF

期刊介绍： The Revista Chapingo Serie Ciencias Forestales y del Ambiente (RCHSCFA) is a scientific journal that aims to raise awareness of high-quality research products related to forest, arid, temperate and tropical environments in the world. Since its foundation in 1994, the RCHSCFA has served as a space for scientific dissemination and discussion at a national and international level among academics, researchers, undergraduate and graduate students, forest managers and public/private entities that are interested in the forest environment. All content published in the journal first goes through a strict triple-blind review process and is published in the following formats: Scientific Articles, Review Articles, Methodologies, Technical or Technological Notes.
