Nutritional Properties and Fertilizer Demand Rules of Young Phoebe bournei Forest

闽楠幼林营养特性及需肥规律研究（英文）

This study aimed to investigate the absorption characteristics of nitrogen, phosphorus, potassium, calcium and magnesium and rules in fertilizer demand by young Phoebe bournei forest. 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.

为探讨闽楠幼林的氮、磷、钾、钙、镁等营养特性及需肥规律,开展了闽楠幼林施肥研究,结果表明:N、P、K、Mg含量随闽楠生长而下降,而Ca的含量随叶龄增长而上升;6月、7月和8月N、P、K、Mg含量相对较高。该文旨在了解闽楠幼林的营养特性以及所需肥料的规律,为闽楠科学施肥提供理论指导。
