在以前对粉煤灰改良石灰性土壤对其理化性质和养分效应研究的基础上，分析了小麦不同生育期土壤中微生物数量和几种重要的土壤酶的活性，旨在探讨石灰性褐土施用粉煤灰配合有机肥对土壤环境生物质量的效应。结果表明，每公顷施用粉煤灰150 t以上显著提高了土壤中各种微生物的数量，对土壤酶活性也有显著的作用，尤其是对小麦灌浆期脲酶的活性有显著的促进作用。因此，施用粉煤灰可以改善土壤的生物活性，从而达到保护和治理土壤环境的效果。

The paper analyzed the soil microbial biomass and soil enzymes activity during wheat growth stages for studying the effects of applying coal ash, chemical fertilizer and green manure on soil biological quality in calcic cinnamon clay soils. The results showed that the soil microbial biomass and enzyme activity were increased especially for urease enzyme in wheat milking stage when the application rate was 150 t/hm2 for coal ash.
