采用完全随机区组设计,通过田间试验,研究不同用量的生物菌肥对晋城大张村采煤沉陷区复垦1年土壤酶活性的影响.结果表明:随着生物菌肥施入量的增加,土壤过氧化氢酶活性逐渐增强,且各处理显著高于对照(P<0.05);生物菌肥施入量为20 g/穴时,土壤脲酶活性最强,达到了0.57 mg/g,且与对照之间差异显著(P<0.05);生物菌肥施入量为10 g/穴时,土壤蔗糖酶活性最强,达到了58.83 mg/g,且与对照之间差异显著(P<0.05).研究表明,生物菌肥对采煤塌陷区复垦土壤的酶活性有一定的积极作用,其结果可为在采煤沉陷区合理有效的开展生物复垦技术提供理论依据.

The objective of this study was to investigate the influences of different bacterial manure levels on the soil enzyme activities in core-mining subsidence area. The results showed that: the catalase activity were increased gradually with the increasing use of bacterial manure, and the catalase activity of all treatments were significantly(P<0.05) higher than those in the control; when the content of bacterial manure was 20 g/xue, the soil urease activity was maximum and reached 0.57 mg/g, which was significantly(P<0.05) higher than that in the control; when the content of bacterial manure was 10 g/xue, the soil saccharase activity was maximum and reached 58.83 mg/g , significant differences(P<0.05) were observed between the treatment and the control. The present study indicated that bacterial manure has positive effects on enzyme activities of soil in core-mining subsided area. The results could provide theoretical evidences for developing biological reclamation technology effectively in core-mining subsided area.
