  • 摘要: 以重庆市九龙坡区和缙云山不同栽植时间和地点的香樟树作为试验对象,通过涂布平板、土壤化学性质测定等方法分析香樟树根际土壤微生物数量、土壤化学性质差异,并对土壤综合肥力进行评价.结果表明,香樟树根际土壤微生物中细菌数量最多,细菌与放线菌的数量随着栽培年限的增加逐渐减少;重庆市九龙坡区香樟行道树土壤呈碱性状态,pH值为8.11~8.13,有机质含量偏低;而缙云山香樟树根际土壤呈碱性,pH值范围在5.2~6.46,其中缙云山-20有机质含量最高.各项指标分析显示重庆市九龙坡区和缙云山香樟树土壤肥力及土壤肥力均处于一般水平,九龙坡区行道树土壤肥力低于缙云山土壤肥力.研究结果通过比较不同地点香樟树的土壤环境,为城市行道树的种植和养护提供科学依据.
    Abstract: Taking Cinnamomum camphora (Linn) Presl planted at different times and locations in Jiulongpo District and Jinyun Mountain of Chongqing as the test objects, the differences on the quantity of rhizosphere soil microbes and soil chemical properties of C. camphora (Linn) Presl were analyzed by coating plate and soil chemical properties determination, and the comprehensive soil fertility was evaluated. The results showed that the number of bacteria in the rhizosphere soil microorganisms of C. camphora was the highest, and the number of bacteria and actinomycetes decreased with the increase of cultivation years. The soil of C. camphora street trees in Jiulongpo District of Chongqing is alkaline, with pH of 8.11~8.13, and low organic matter content. The rhizosphere soil of C. camphora in Jinyun Mountain is alkaline, with pH ranging from 5.2 to 6.46, among which the content of organic matter in Jinyun Mountain-20 was the highest. The analysis of various indicators showed that the soil fertility and fertility of C. camphora (Linn) Presl tree soil in Jiulongpo District and Jinyun Mountain of Chongqing were at a general level. The soil fertility of street trees in Jiulongpo District was lower than that in Jinyun Mountain. The results of this study provide a scientific basis for the cultivation and conservation of street trees in urban areas by comparing the soil environment of C. camphora (Linn) Presl in different locations.
