摘 要
本研究旨在深入探讨枫香树的天然更新机制，并提出有效的促进技术。通过野外调查与实验分析，我们系统研究了枫香树的种子扩散、萌发条件及幼苗生长特性。结果表明，枫香树种子主要通过风力传播，其萌发受土壤湿度、光照条件及种子自身质量等多重因素影响。我们进一步发现，适宜的土壤温度和湿度能显著提高种子萌发率，而适度的遮荫则有利于幼苗生长。基于这些发现，我们创新性地提出了一套枫香树天然更新促进技术，包括优化种子采集与储存方法、改善种子萌发环境以及科学管理幼苗生长等措施。本研究不仅丰富了枫香树生态学理论，还为枫香树资源的可持续利用提供了实践指导。

Abstract
This study aims to explore the natural renewal mechanisms of maple trees and propose effective facilitation techniques. Through field investigation and experimental analysis, we systematically studied the seed dispersal, germination conditions and seedling growth characteristics of maple gum tree. The results show that the maple seeds are mainly transmitted by wind, and their germination is affected by multiple factors such as soil moisture, light conditions and seed quality. We further found that suitable soil temperature and moisture significantly increased seed germination rate, while moderate shade was beneficial to seedling growth. Based on these findings, we innovatively propose a set of natural renewal promotion techniques for maple gum tree, including optimizing seed collection and storage methods, improving seed germination environment, and scientific management of seedling growth. This study not only enriches the theory of Chinese maple tree ecology, but also provides practical guidance for the sustainable utilization of the Chinese maple tree resources.
