- 摘要:
- 以2株YA、YD有益促生菌为试材，以盆栽蓝莓为试验对象，采用微生物稀释培养法研究了接种(穴施)YA、YD菌根真菌及土壤拌硫磺对根际土壤微生物数量和生物多样性的影响，以期为复合微生态生物制剂的研制及其应用提供理论依据。结果表明：不同处理后土壤根际微生物各生理类群数量差异显著，接种菌根真菌后细菌数量减少，真菌数量增多，放线菌没有明显变化，接种后土壤微生物多样性指数有显著提高，其变化趋势与土壤微生物数量的变化趋势不一致。
- Abstract:
- Taking two different mycorrhizal fungi YA,YD as materials,using microbial dilution plate counting cultivation method,the effects of different mycorrhizal fungi on soil microbial number in the blueberry rhizosphere were studied with pot experiment,in order to provide the basis for development and application of mycorrhizal fungi.The results indicated that the number of microbial physiological groups in rhizosphere soil of different varieties under different treatments had significantly differences,and bacteria decreased,fungi increased with actinomycetes no significant change.Rhizosphere soil microbial diversity index of different treatments improved highly.Its change trend was not in accordance with microbial quantity.
