| 英文摘要 | Nitrogen (n) cycling in agro-ecosystems is likely to change under elevated o-3 (eo(3)) as a result of changes in plant material inputs to soils. the objective of this study was to understand how eo(3) could change key n cycling processes in soils. rhizosphere soils were collected from sensitive and tolerant wheat cultivars following a 5-year fumigation of o-3 at 60 ppb (eo(3)) and at ambient 40 ppb (ao(3)) in a free-air ozone enrichment platform. soil nitrifying and denitrifying enzyme activity (nea and dea), abundance of ammonia monooxygenase(amoa) and denitrifying bacteria genes(nirs and nirk), and other related properties were quantified. soil nea, dea, nh4 (+) and no3 (-) were higher under eo(3) than under ao(3), whereas microbial biomass n (mbn) decreased under eo(3), especially with the o-3-sensitive cultivar. no clear eo(3) effect was observed on the abundance of amoa and nirs and nirk. grain yield and shoot to root ratios decreased as a result of eo(3) in the o-3-sensitive cultivar. eo(3) stimulates soil n availability, but suppresses grain yields after 5 years, especially for the o-3-sensitive cultivar. adaptive strategies should focus more on cultivar selection to retain n in soil and to assure the resilience of crop production in the future. |
