分析山东平度和新疆库尔勒2个地区在不同肥力下土壤微生物数量消长与土壤元素含量之间的相关性。结果表明:在不同施肥处理下,2个地区细菌、放线菌数量显著增长,真菌数量呈减少趋势,其中施有机肥比化肥对真菌增长影响达极显著;不施肥种植(CK)显著降低土壤微生物总体数量,但不影响微生物群落结构比率;2个地区土壤微生物消长与土壤元素间相关性不完全一致,2个地区真菌数量消长与铜元素均呈极显著负相关,平度点细菌数量与锌元素呈极显著性正相关,与硼元素极显著负相关,与锰显著负相关。土壤养分种类及含量水平对土壤微生物数量消长影响极显著,而土壤微生物消长在不同土壤环境下与根围土壤元素含量相关性不尽相同。
The correlation between soil microbial quantity and soil microbial biomass under different fertility levels in Pingdu, Shandong and Korla, Xinjiang was analyzed. The results showed that under different fertilization treatments, the number of bacteria and actinomycetes increased significantly in both areas, while the number of fungi decreased. The effect of applying organic fertilizer on fungi growth was more significant than that of chemical fertilizers. No fertilization (CK) The total number of microorganisms does not affect the microbial community structure ratio. The correlation between soil microbial growth and soil elements in the two areas is not completely consistent. The growth and decline of fungi in both areas are significantly and negatively correlated with the contents of copper. Zinc is extremely significant positive correlation, extremely significant negative correlation with boron, negative correlation with manganese. Soil nutrient types and content levels have a significant impact on soil microbial population growth, while soil microbial growth and rhizosphere soil element content in different soil environments are not the same.
