| 摘 要： | 从湛江市东海岛大坝红树林区和非红树林区采集土壤样品,采用稀释平板涂布法进行细菌、放线菌和真菌的分离;采用滴定法对过氧化氢酶和蔗糖酶进行酶活性的测定.采用比色法对脲酶和多酚氧化酶进行酶活性测定.试验结果表明,土壤中细菌数量最多.其次是放线菌.真菌数量最少.通过比较发现.红树林土壤微生物数最多于非红树林土壤微生物数量,且不同红树植物林地土壤微生物多少也不一样.从酶的活性看,红树林土壤过氧化氢酶、蔗糖酶和脲酶活性高于非红树林土壤,且这几种酶的活性与土壤微生物的数量呈正相关.

| Abstract: | The soil samples were collected from the mangrove area and non-mangrove of the Donghai Island of Zhanjiang City. Bacteria, actinomycetes and fungi were isolated with dilution spread plate method from soil samples. Activities of Catalase and sucrase were determined using titration method and activities of urease and polyphenoloxidase were determined using spectrophotometry method. The results showed that bacteria was the most, actinomycetes was the second and fung was the least in quantity. Soil microorganism quantity of mangrove were more than that of non-mangrove. Catalase, sucrase and urease activity of Kandelia candel were the highest, but polyphenoloxidase activity was the lowest. Catalase, sucrase and urease activity of mangrove was higher than that of non-mangrove. Catalase, sucrase, urease activities were positive correlative with soil microorganisms. |
