摘要

本研究針對臺灣不同地區土壤化學性質對烏心石生長之影響進行探討並作為生育地栽植參考。分別調查12個縣市烏心石生長狀態、分析土壤性質並比較土壤化學性質對烏心石生長之相關性。結果顯示12個縣市中烏心石胸徑及樹高分別以苗栗縣及雲林縣最大。另一方面，12個縣市中土壤全碳量及陽離子交換容量分別以屏東縣及宜蘭縣有較高含量。比較12縣市生長狀態及土壤因子之相關性顯示烏心石胸徑及樹高與土壤陽離子交換容量及可交換性陽離子顯著相關，代表烏心石生長狀態與土壤因子有關。

The aims of this study were to investigate the effect of Michelia formosana growth status by soil chemical properties and also to establish an evaluation of soil properties for Michelia formosana planting. Michelias formosana growth status and soil properties were investigated from 12 counties in Taiwan. Results showed that the diameter at breast height (DBH) and tree height of Michelia formosana were largest in Maoli and Yunlin counties, while soil organic carbon and cation exchange capacity (CEC) were largest in Pengdong and Ilan counties. The significant relationships between tree growth status of DBH and height and soil properties of CEC and exchangeable cations indicated that the growth status of Mechelia formosana was affected by soil factors.
