摘 要
优良乡土树种在生态系统恢复和城市绿化中具有不可替代的作用，但其繁殖技术研究相对滞后，限制了实际应用。本研究以我国典型优良乡土树种为对象，系统分析了其种子萌发、无性繁殖及组培快繁的技术特点，并结合具体案例探讨了不同繁殖方式的适用条件与优化策略。通过对比试验与数据分析，明确了影响乡土树种繁殖效率的关键因素，提出了基于环境适应性的繁殖技术改进方案。研究表明，采用综合繁殖技术可显著提高乡土树种的成活率与繁殖速度，同时降低生产成本。此外，本研究首次构建了乡土树种繁殖技术评价体系，为科学选择繁殖方法提供了理论依据。结果表明，优良乡土树种在生态修复、景观营造及经济林建设等方面具有广阔的应用前景，其推广将有效促进区域生物多样性和可持续发展。该研究为乡土树种的大规模应用奠定了技术基础，也为相关领域的深入研究提供了新思路。

Abstract
Indigenous tree species of high quality play an irreplaceable role in ecosystem restoration and urban greening; however, the research on their propagation technologies lags behind, limiting practical applications. This study focuses on typical indigenous tree species in China, systematically analyzing the technical characteristics of seed germination, asexual propagation, and tissue culture rapid propagation. By integrating specific case studies, it explores the applicable conditions and optimization strategies for different propagation methods. Through comparative experiments and data analysis, key factors influencing the propagation efficiency of indigenous tree species were identified, and an improved propagation technology scheme based on environmental adaptability was proposed. The study demonstrates that the adoption of integrated propagation technologies can significantly enhance the survival rate and propagation speed of indigenous tree species while reducing production costs. Additionally, this research establishes, for the first time, an evaluation system for the propagation technology of indigenous tree species, providing a theoretical basis for scientifically selecting propagation methods. The results indicate that high-quality indigenous tree species have broad application prospects in ecological restoration, landscape creation, and economic forest construction, with their promotion effectively contributing to regional biodiversity and sustainable development. This research lays a technical foundation for the large-scale application of indigenous tree species and offers new insights for further studies in related fields.
