摘要
为了探索温度升高处理下油松枯落物的响应机制,通过应用开顶箱人工模拟升温处理,以自然温度条件作对照处理,开展了沙地油松枯落物分解试验研究。结果表明:升温处理下油松枯落物的枝、叶中含水率及质量残余率均高于对照处理,且叶的含水率大于枝的含水率,叶的质量残余率低于对照的质量残余率。可见,升温条件抑制了油松枯落物的分解,其中对油松枝枯落物分解的抑制作用更强。
In order to explore the response mechanism of Pinus tabulaeformis litter under elevated temperature treatment,this study was conducted by applying open-top box artificial simulation of heating treatment and natural temperature conditions as a control treatment.Result shows that the water content and mass residual rate of the branches and leaves of Pinus tabulaeformis litter under the heating treatment are higher than the control treatment,and the water content of the leaves is greater than the water content of the branches,and the mass residual rate of the leaves is lower than that of the control.Therefore,it can be seen that the heating conditions inhibited the decomposition of Pinus tabulaeformis litter,and the inhibitory effect on the decomposition of Pinus tabulaeformis branch litter is stronger.
