| 摘 要： | 以10种不同树龄的橡胶树无性系PR107为研究材料，在一年内不同月份采集叶片，分析叶片中的全氮、全磷、全钾、全钙和全镁百分含量，比较不同树龄PR107叶片养分含量之间的差异，研究结果表明：（1）各年龄段橡胶无性系PR107树叶全氮、全磷、全钾、全钙和全镁百分含量随月份的变化波动比较大，在一年中的不同月份差异达极显著，叶片中N、P、K、Ca、Mg百分含量受叶龄影响明显；（2）在相同月份，各年龄段橡胶无性系PR107树叶全氮、全磷、全钾、全钙和全镁百分含量变化波动比较大，不同年龄树体之间差异达极显著，叶片中N、P、K、Ca、Mg百分含量受橡胶树年龄影响明显；（3）对橡胶无性系PR107树叶养分百分含量进行回归分析，全氮、全磷、全钾、全钙和全镁百分含量与叶龄、树龄二元线性回归达极显著。

| Abstract: | Leaf samples were collected each month in a year from the rubber trees of Clone PR107 (Hevea brasiliensis) at 10 different tree ages,and their contents of N,P,K,Ca and Mg were determined and compared.The leaf contents of N,P,K,Ca and Mg of the rubber trees of various ages fluctuated intensively with month,were highly significantly different between months in a year,and were obviously affected by the leaf age.In the same month,the leaf contents of nutrient elements,N,P,K,Ca and Mg,of the rubber trees at diff... |
