摘  要：
为了探讨烤烟根际土壤微生物对土壤物理特性的影响,以湘西定位试验田烤烟根际土壤为试验材料,通过盆栽试验,研究了接种烤烟根际土壤微生物后对不同时期土壤容重、田间持水量、总孔隙度及三相比等参数的影响。结果表明:接种烤烟根际土壤微生物主要对烤烟生育中后期时土壤物理特性影响较大,能降低土壤容重和固相比,提高土壤总孔隙度;接种烤烟根际土壤微生物有利于烤烟生育后期时土壤田间持水量的提高,当土壤田间持水量整体处于较高水平时(19%～20%),接种烤烟根际土壤微生物对土壤田间持水量影响较小,而当土壤田间持水量整体处于较低水平时(14%～18%),接种烤烟根际土壤微生物后能缓解土壤田间持水量降低的趋势;另外,接种烤烟根际土壤微生物对土壤液相及气相比影响较小。

摘  要：
In order to explore the influence of rhizosphere soil microorganisms of the flue-cured tobacco planting on soil physical characteristics, soil bulk density, field water-holding capacity(FWHC), total porosity and percentage of soil three phases in different periods were analyzed in potted experiment of Xiangxi. The results showed that inoculating rhizosphere soil microorganisms of flue-cured tobacco planting had a great influence on soil physical characteristics in the middle and later growth stage of flue-cured tobacco. The soil bulk density and percentage of solid phase were reduced and the total porosity of soil was improved after inoculating rhizosphere soil microorganisms of flue-cured tobacco planting. The inoculation of rhizosphere soil microorganisms increased the FWHC at the later growth stage of flue-cured tobacco. The influence of inoculating rhizosphere soil microorganisms on soil FWHC was lower at 19% ～ 20% FWHC. And it alleviated the reduction of soil FWHC at 14% ～ 18% FWHC. In addition, the percentages of liquid phase and gaseous phase were less affected by inoculating rhizosphere soil microorganisms of flue-cured tobacco planting.
