摘要

为了解油松(Pinus tabuliformis)天然林新生枝叶碳(C)、氮(N)、磷(P)化学计量特征对土壤氮浓度改变的响应及其林龄差异

揭示不同龄级油松新生枝叶N、P元素内稳态对短期氮添加的响应。以关帝山林区孝文山林场Ⅴ~Ⅶ龄级油松天然次生林为研究对象

采用野外原位氮添加试验的方法

设置对照(N0

0)、低氮(N1

5 g/m2)、中氮(N2

10 g/m2)和高氮(N3

15 g/m2)4个施氮水平

形成不同土壤N浓度梯度

分析不同N浓度新生枝和叶C、N、P计量指标和内稳态指数。油松枝叶C、N、P含量随土壤氮浓度的增加而显著增加

C/N和C/P减小;油松枝叶C含量、C/N和C/P随龄级增加而增加

N、P含量随龄级增加而减少;根据针叶N/P

该地区油松生长主要受N限制;新生枝和叶N、P含量及N/P与土壤指标的关系均能很好被内稳态模型模拟(p＜0.1)

其中新生枝P含量对土壤供氮水平变化敏感

而其他指标较稳定

新生叶的内稳态高于新生枝。该地区油松通过调节枝叶氮磷吸收与利用策略保持新生枝叶内稳态以适应土壤氮浓度增加及由此带来的变化。

Abstract

To understand the response of carbon (C)

nitrogen (N) and phosphorus (P) stoichiometric characteristics of the new branches and leaves in natural Pinus tabulaeformis forest to changes in soil nitrogen concentration and differentstand age

and to reveal the response of N and P homeostasis in the new branches and leaves of Pinus tabuliformis at different stand ages to short-term nitrogen addition

taking the natural secondary forest of Pinus tabulaeformis with age V~VII of Xiaowen mountain forest farm in Guandi mountain forest area as the research object

the field in-situ comparative test with different nitrogen application rates was used to set four nitrogen application levels:control (N0

low nitrogen (N1

5 g/m2)

medium nitrogen (N2

10 g/m2) and high nitrogen (N3

15 g/m2)

and the contents of C

N and P in new branches and leaves and their stoichiometric ratios and homeostasis indexes were analyzed under different soil nitrogen concentrations.The contents of C

N and P in the branches and leaves of Pinus tabulaeformis increased significantly with the increase of soil nitrogen concentration

while the contents of C/N and C/P decreased;the contents of C

C/N and C/P in the branches and leaves of Pinus tabulaeformis increased with the increase of forest age

while the contents of N and P decreased with the increase of forest age;according to leaf N/P

the growth of Pinus tabulaeformis in this area was mainly limited by N;the relationship between N

P and N/P in new shoots and leaves with corresponding soil parameters could be adequately simulated by an internal homeostasis model (p＜0.1)

the content of P in new shoots was sensitive to the change of soil nitrogen supply level

while the other indexes were stable

and the homeostasis of new leaves was higher than that of new shoots.The Pinus tabulaeformis maintained the internal stability of new branches and leaves by adjusting nitrogen and phosphorus uptake and utilization strategies to adapt to the increase of soil nitrogen concentration and the resulting changes.
