| 英文摘要 | Nitrogen (n)-fixing species have a function to enrich n in soil. mixing n-fixing shrub species into poplar stands can be assumed as a measure to increase productivity while improving soil fertility. to verify this assumption and to understand the temporal influences of n-fixing shrub species mixed into poplar plantations on soil fertility, we investigated selected soil chemical and microbial properties in pure poplar (populus x xiaozhuanica w. y. hsu et liang) and mixed poplar-seabuckthorn (hippophae rhamnoides l) stands at ages of five and 15 years in a semi-arid region of northeast china. both stands at age of five have similar values of aboveground biomass, total soil organic c concentration, total n concentration, microbial biomass c, and metabolic quotient; however, at age of 15, these values except for soil metabolic quotient are significantly greater in mixed poplar-seabuckthorn stand than in pure poplar stand. the soil metabolic quotient is lower in the former stand than in the latter stand. our results suggest that, in semi-arid regions, mixing n-fixing shrub species into poplar plantations can improve soil fertility in a long run rather than in a short term; therefore, mixing n-fixing shrub species into poplar stands is an option to improve soil fertility and increase productivity in a long run.
