| 摘 要： | 利用BIOLOG技术研究了新疆富蕴地震断裂带6种次生植物对根际土壤微生物碳源利用的影响.结果表明:多数植物根际土壤养分显著高于对照.6种根际土壤的平均颜色变化率差异显著,且均高于对照.次生植物不影响根际土壤微生物碳源利用的丰富度,但改变了其优势度和均匀度.不同处理根际土壤微生物碳源利用存在差异,主要体现在对糖类、氨基酸类、羧酸类的利用上.断裂带上次生植物的出现使土壤微生物利用碳源的类型由酚类向糖类、羧酸类转变.土壤速效钾含量与土壤微生物对聚合物(r=-0.84)、胺类(r=-0.83)的利用呈负相关.新疆地震断裂带的次生植物能显著增强土壤微生物的碳源利用能力,改变碳源利用类型.密刺蔷薇和蓍在提高土壤微生物碳源利用能力和改善土壤养分方面效果最佳.

| Abstract: | By using BIOLOG technique, this paper studied the microbial carbon utilization in the rhizosphere soils of six kinds of secondary plants in Fuyun earthquake fault zone of Xinjiang. Most of the rhizosphere soils had significantly higher nutrient contents, and all of them had a higher AWCD, as compared with the control. There was a distinct difference in the AWCD among the six rhizosphere soils. Secondary plants less affected the richness but changed the dominance and evenness of the microbial carbon sources ... |
