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20g/穴时,土壤脲酶活性最强,达到了0.57mg/g,且与对照之间差异显著(P<0.05);生物菌肥施入量为10g/穴时,土壤蔗糖酶活性最强,达到了58.83mg/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。
A completely randomized block design and field experiments were conducted to study the effects of different amounts of biological microbial fertilizer on soil enzyme activities in the reclaimed area of Dachang village, Jincheng, a year after field trials. The results showed that the activities of soil catalase gradually increased with the increase of the amount of biological manure applied, and the treatments were significantly higher than those of the control (P <0.05). When the amount of biological bacterial fertilizer was 20g / The highest activity reached 0.57 mg / g, with significant difference (P <0.05) compared with the control. When the amount of bio-fertilizer applied was 10 g / well, the soil invertase activity was strongest, reaching 58.83 mg / g, There was significant difference between control and control (P <0.05). The results show that the bio-fertilizer has a certain positive effect on the activity of reclaimed soil in the mining subsidence area, and the results can provide a theoretical basis for carrying out biological reclamation technology in the coal mining subsidence area.
