摘　　要：通过对水稻土壤连续两年施用硅酸盐细菌复合肥料,研究其对土壤微生物量和土壤理化性质的影响,结果表明,施用硅酸盐细菌肥料可提高土壤的细菌、真菌、放线菌等微生物量,增强土壤几种酶的活性,改善土壤生态,提高土壤肥力,降低土壤容重,提高阳离子代换量,增加土壤速效磷、碱解氮和速效钾的含量,且与有机肥混施效果更佳。Through the use of bacteria silicate compound fertilizer on rice soil for two consecutive years, study of effect on soil microorganisms and soil enzyme activity was completed. The results showed that the use of silicate bacteria fertilizer could increase soil bacteria, fungi and aetinomycetes amount , enhance several enzymes activity of soil, remedy the soil ecology , improve soil fertility , reduce soil bulk density, increase the cation exchange capacity and increase soil available phosphorus, nitrogen and potassium content. The effect was better when it was mixed with organic fertilizer.
