| 摘 要： | 目的]比较分析不同地形因子对杉木叶有效养分的影响。方法]以第3代杉木种子园为研究对象,分析不同坡向和坡位杉木第3代种子园杉木当年生结果枝叶有效养分含量差异。结果]同一坡向随着坡位上升,第3代杉木种子园杉木当年生叶有效养分含量呈逐渐下降趋势;同一坡位不同坡向对杉木当年生叶有效养分含量的影响体现出较为复杂的规律。结论]在杉木种子园施肥过程中应结合土壤状况、植株养分含量、不同地形因子等进行合理施肥配方。

| Abstract: | Objective] To compare the influence of different site factors on the available nutrients content in C.lanceolata leaves.Method] With the third-generation seed orchard of C.lanceolata as the study object,the available nutrients contents in the C.lanceolata leaves planted in different slope and aspects were determined.Result] At the same aspect,the leaf nutrients contents was gradually decreasing with the elevated slope altitude;at the same slope altitude,the change of nutrients contents presented complicated rules at different aspects.Conclusion] The fertilization of the seed orchard of C.lanceolata should be based on local soil conditions,plant nutrients content and different site factors,etc.. |
