为研究不同施肥方式对大豆根际土壤微生物数量及土壤肥力影响,采用无肥、常规肥、有机肥、常规施肥+生物肥4种肥料处理,分别于大豆播种前、苗期、花期、鼓粒期和成熟期对大豆根际土壤的细菌、真菌、放线菌进行测定。结果表明:肥料的施用可提高土壤微生物的数目及土壤肥力,其中有机肥处理与常规肥+生物肥处理在大豆各生育时期可明显增加土壤中细菌、真菌及放线菌数目;与无肥处理相比,常规肥、有机肥及常规肥+生物肥处理提高了土壤肥力。
In order to study the effects of different fertilization modes on soil microbial quantity and soil fertility in soybean rhizosphere, four kinds of fertilizers including no fertilizer, conventional fertilizer, organic fertilizer and conventional fertilization + biological fertilizer were used to treat soybean before sowing, seedling, anthesis, Period and maturity of soybean rhizosphere soil bacteria, fungi, actinomycetes were determined. The results showed that: the application of fertilizer can increase the number of soil microorganisms and soil fertility, of which organic manure treatment and conventional fertilizer + biological fertilizer treatment can significantly increase the number of bacteria, fungi and actinomycetes in soils at different growth stages; Compared to conventional fertilizers, organic fertilizers and conventional fertilizer + biological fertilizer increased soil fertility.
