摘　　要：进行了化肥、有机肥、生物堆肥、有机无机复合肥和生物有机无机复合肥的田间比较试验。结果表明 :生物有机无机复合肥显著提高土壤微生物活性。与不施肥处理比较 ,土壤细菌增加了 1 6 5 .3 8% ,真菌增加了1 89.4 7% ,放线菌增加了 4 8.72 % ,总量增加了 1 0 4 .0 7% ,其增加量高于其他处理。土壤蔗糖酶、脲酶、磷酸酶活性也都有明显提高 ,促进了土壤有机质的分解转化和速效养分的释放。A comparative experiment was conducted in the field on efficiencies of chemical fertilizer,organic manure,biological compost,organic-inorganic complex fertilizer and biological-organic-inorganic complex fertilizer.The results show that the last type of fertilizer could significantly improve soil biological activities.Compared with that of the soil no fertilizer,the population of bacteria increased by 165.38%,of fungi by 189.47%,of actinomycetsby 48.72%,and the total population of the three sorts of microorganisms by 104.07%.The increments is higher than those in any other treatments in the experiment.The activities of invertase,urease and phosphatase in the soil also increased obviously,thus enhancing the decomposition and transformation of soil organic matter and release of soil available nutrient elements.
