| 英文摘要 | Eleven agricultural soils were collected from Chinese uplands and paddy fields to compare their denitrification activities under identical laboratory conditions. Before starting the assays, all air-dried soils were pre-incubated for 4 weeks at 25degreesC and 40% WFPS (water-filled pore space). N2O and N-2 production potentials in various Chinese agricultural soils by denitrification were determined by acetylene inhibition method at 25degreesC and 80% WFPS for 2 d incubation, with or without KNO3 (200 mg N kg(-1) soil) addition. The N2O and N-2 productions by denitrification from soils with KNO3 addition were 0.17 and 0.35 mug N kg(-1) d(-1) on average, ranging between 0.04-0.55 and 0.10-1.33 mug N kg(-1) d(-1), respectively. The denitrified N increased by 200 mg N kg(-1) KNO3-N addition was 0.22 mug N kg(-1) d(-1) on average and ranged between 0.01-1.40 mug N kg(-1) d(-1). No relationships were found between gases productions (N2O, N-2, and CO2) from 3 kinds of denitrification assays and soil properties such as bulk density, total C, total N, soluble C, microbial biomass C, and NO3--N concentration. However the denitrified N from soils without KNO3 addition had significantly negative correlation with the pH of soils (p < 0.05). Among 11 soils, the Ultisols acid paddy soil had the strongest denitrification activity. There was significant correlation between CO2 production and N2O and N-2 productions from 3 kinds of denitrification assays. |
