为了解杉木林地和根际土壤酚类物质的含量与动态变化，同时也为了和阔叶林地及连栽林地进行比较，作者采样分析了杉木１代、２代以及檫树林地林间和根际土壤的酚类物质。结果显示：①杉木檫树两林木根际土壤总酚含量均显著高于其林间土壤，Ｒ／Ｓ值平均是１．６１和１．６７，但两种林木之间无论是根际土壤还是林间土壤总酚含量无明显不同；②杉木根际土壤游离酚含量显著高于檫树根际土，平均是檫树根际土的１１．９倍；③从１年的动态变化来看，两种林木的根际和林间土壤总酚，游离酚含量均从１月到７月呈上升趋势，７月以后又重新回落；④杉木连栽造成了林间土壤游离酚含量明显增加，２代杉木林地土壤游离酚含量是１代林地的１．３７倍，但连栽并未改变杉木林间和根际土壤总酚含量，根际土壤游离酚含量也没有发生明显的变化。
In order to understand the contents and dynamic changes of phenols in Chinese fir plantation and rhizosphere soil, and to compare with the broadleaf forest and even the plantation, the authors sampled and analyzed the phenological contents of the 1st and 2nd generation of Chinese fir plantation and rhizosphere Soil phenols. The results showed that: ①There were significantly higher total phenolics content in the rhizosphere soil than that in the forest soil, with the average R / S values being 1.61 and 1.67, respectively. However, The contents of total phenols in forest soil were not significantly different. ②The free phenol content in the rhizosphere soil of Chinese fir was significantly higher than that of the rhizosphere soil of Rhodiola spp., Which was 11.9 times of that of the rhizosphere soil of Rhizome. On the basis of the dynamic changes of 1 year, The contents of total phenols and free phenols in the rhizosphere soil and forest soil of both forest types increased from January to July, and then dropped back again after July. ④ Continuous plantation of Chinese fir caused a significant increase of free phenol content in the forest soil. 2 In the Chinese fir plantation, the content of free phenol was 1.37 times of that of the first generation, but the continuous plantation did not change the content of total phenols in the rhizosphere soil and rhizosphere soil, and the content of free phenol in rhizosphere soil did not change obviously.
