| 为研究施肥方式在采煤塌陷复垦初期土壤质量改良中的应用效果，以塌陷区复垦1 年的土壤
为研究对象，通过绿肥、绿肥+ 化肥、绿肥+ 菌肥、绿肥+ 化肥+ 菌肥处理，研究不同施肥方式对土壤微生
物数量和群落组成的影响。结果表明：不同施肥处理均能显著提高土壤微生物的数量，但不同施肥处理对
微生物数量的影响程度不同，其中，绿肥+ 化肥+ 菌肥处理下土壤微生物总数量增加最多，黑麦草+ 化肥+
菌肥处理和苜蓿+ 化肥+ 菌肥处理的微生物总数量比对照分别提高430.1% 和387.9%；微生物各类群在不
同施肥处理下数量变化幅度的顺序为：放线菌> 细菌 > 真菌，其中，各处理放线菌数量比对照增加2.4～5.8
倍、细菌数量比对照增加2.0～4.2 倍、真菌数量比对照增加1.5～3.5 倍。表明不同施肥处理对采煤塌陷区
复垦土壤微生物均有促进作用，以绿肥+ 化肥+ 菌肥处理的效果最好。 |

| To investigate the effects of fertilization treatments on soil quality of mine reclaimed land，this study
evaluated the effects of different fertilization treatments on soil microbial community in core-mining subsidence
area. Eight kinds of fertilization treatments and one control treatment were set in 1-year reclaimed soil，including
ryegrass treatment，alfalfa treatment，ryegrass+chemical fertilizer treatment，alfalfa+chemical fertilizer treatment，
ryegrass+microbial fertilizer treatment，alfalfa+microbial fertilizer treatment，ryegrass+chemical+microbial fertilizer
treatment，alfalfa+chemical+microbial fertilizer treatment. The results showed that：fertilization treatments had
certain roles in promoting the quantity of soil microorganism，but the impact of different fertilization treatments on the
quantity of soil microorganism varied. And the treatment of green manure+chemical fertilizer+ microbial fertilizer had
the most remarkable influence on the quantity of soil microorganism，with the increases by 430.1% and 387.9% under
ryegrass+chemical+microbial fertilizer treatment and alfalfa+chemical+microbial fertilizer treatment than the control.
The range of change in quantity of soil microorganism was in order of actinomyces>bacteria>fungl；The quantity of
actinomyces，bacteria and fungl was 2.4-5.8，2.0-4.2 and 1.5-3.5 times higher under fertilization treatments than
that under control. This result indicated that fertilization treatments simulated the of soil microorganism in coremining
subsidence area. And the treatment was the most effective when green manure chemical fertilizer and microbial
fertilizer mixed together. |
