The results showed that the nitrogen, phosphoruS, potassium and magnesium contents in young Phoebe bournei leaves were increased with the proceeding of growth, but the calcium content was increased. During the growth period, the nitrogen, phosphorus, potassium and magnesium contents were relatively high in June, July and August. This study will help to understand the nu- tritional characteristics and fertilizer demand rules of young Phoebe boumei forest, thereby providing scientific theoretical guidance for application of fertilizer in Phoebe bournei.展开更多
