摘　　要：研究了施用生物菌肥和农家肥两种有机物料对草甸型水稻土物理和化学性质的影响．研究表明，施用有机物料能够改善土壤的理化性质，使土壤容重下降，总孔度增加，田间持水量增大，大小孔隙比例协调；增加了土壤有机质和各种养分含量，培肥土壤．其中，生物菌肥效果明显．从产量和培肥土壤综合效果来看，生物菌肥和化肥配施是最有效的施肥方式．Effect of application bacterial mature and farmyard mature on soil physical and chemical properties were studied.The result shows,it can improve soil physical and chemical properties,bring low soil bulk density,increase soil porosity and field capacity,coordinate pore size distribution,increase organic matter and nutrient content.Bacterial mature is distincter than other treatment.On rice yield and soil fertility,application of combining bacterial mature and chemical fertilizer is the best method.
