以锰矿渣废弃地为对照地,研究了湘潭锰矿渣废弃地栾树(Koelreuteria paniclata)、杜英(Elaeocarpus de-cipens)人工混交林(修复地)对土壤微生物数量与酶活性的影响.结果表明:修复地和对照地土壤微生物以细菌数量最多,放线菌数量其次,真菌数量最少.修复地(0-60cm)土层微生物总数、细菌、真菌、放线菌数量比对照地的分别高出36.05%,43.32%,23.58%,6.54%.同一土层中,修复地微生物总数、细菌、真菌、放线菌数量均显著高于对照地(p＜0.05),同一季节.修复地微生物总数、细菌、真菌、放线菌数量也基本上高于对照地.修复地(0-60 cm)土层脲酶、蔗糖酶、过氧化氢酶活性均高于对照地.且同一土层中,修复地和...

Wasteland having been formed with the slag heaps being regarded as contrast land, effects on soil microbe quantity and enzyme activities of artificial restore-mixed stands （restored forestland） of paniculed goldraintree （Koelreuteria paniclata Laxm） and common elaeocarpus （Elaeocarpus decipens） were conducted in the slag wasteland of Xiangtan manganese mine, Hunan province. Results showed that bacteria amounts were the most, aetinomyces amounts were the next, and fungi amounts were the least among composition of three communities of soil ...
