采用田间小区试验,分别以稻草、猪粪、猪粪堆肥和沼渣沼液与化肥配施,研究不同有机肥与化肥配施对双季稻田土壤可培养微生物及土壤有机碳与总氮含量的影响。结果表明:有机肥与化肥配施,尤其是以猪粪堆肥与化肥配施有利于提高稻田土壤中可培养细菌、真菌和放线菌数量、土壤微生物生物量碳(SMBC)和土壤微生物生物量氮(SMBN)含量,促进土壤有机碳(SOC)和氮素累积;与施纯化肥相比,以20%的猪粪堆肥代替20%的化肥氮施用2年后,土壤可培养细菌、真菌和放线菌数量分别提高了38.07 %、9.9 %和27.01 %,SMBC、SMBN、SOC、TN含量分别提高了125.62 %、134.26 %、60.47 %和13.44 %。

Field plot trial was conduct ed to study the effects of straw, pig manure, manure composting or biogas manure combined with chemical fertilizer on cultivable microorganisms and organic carbon and total nitrogen in double cropping paddy soil. Results showed that combinations of organic and chemical fertilizer, especially the combination of pig manure composting and chemical fertilizer, increased the numbers of cultivable bacteria, fungi and actinomycetes and the contents of soil microbial biomass carbon and nitrogen in paddy soil, as well as the contents of soil organic carbon and total nitroge...
