摘要
本文研究了元宝槭幼苗在不同土壤pH值条件下的生长响应。通过设置多个pH梯度的土壤条件，观察元宝槭幼苗的生长状况，包括根系发育、株高、叶面积和生物量等指标的变化。结果表明，土壤pH值对元宝槭幼苗的生长有显著影响。适宜的土壤pH范围能促进元宝槭幼苗的健康生长，而过低或过高的pH值则抑制其生长。研究发现，pH值约为5.5至6.5时，元宝槭幼苗表现出最佳的生长状态。本文结果为元宝槭的栽培管理和土壤环境优化提供了科学依据。

Abstract
This study investigates the growth responses of Acer truncatum seedlings under different soil pH conditions. By setting multiple soil pH gradients, the growth status of the seedlings was observed, including root development, plant height, leaf area, and biomass. The results indicate that soil pH significantly affects the growth of Acer truncatum seedlings. An appropriate soil pH range promotes healthy growth, while too low or too high pH values inhibit it. The study found that seedlings exhibited optimal growth at a soil pH of approximately 5.5 to 6.5. These findings provide a scientific basis for the cultivation management and soil environment optimization of Acer truncatum.
Key words： Acer truncatum; Soil pH; Seedling growth; Growth response; Cultivation management
