- 摘要:
- 为探究白浆土及其改良，采用四段犁对白浆土进行改土深松，研究改良后的白浆层土壤微生物数量及其作物产量的变化。结果表明：与对照相比,四段犁深松不仅可增加白浆土白浆层土壤微生物数目，增加细菌数目311.03%，真菌数目289.31%，放线菌数目356.39%，增加微生物总数320.55%，而且可增加大豆株高、单株荚数、单株粒数，并提高大豆产量6.71%。
- Abstract:
- For the purpose of exploring planosol and its improvement,Four-stage Plough was used to subsoil planosol to study change of soil microorganisms and soybean yield.The results showed that compared with the control,with Four-stage Plough could increase the number of bacteria by 311.03%,the number of fungi by 289.31%,the number of actinomycetes by 356.39%.The microbial amount was increased by 320.55%.Moreover,it could increase plant height,pot number per plant,grains number per plant and soybean yield by 6.71%.
