摘要:
通过室内模拟的方法,研究了潮土两种粒径范围(≤1 cm粒径,简称1 cm粒径;≤0.25 mm,简称0.25 mm粒径)土壤在冻融过程中N2O排放的特征. 结果表明,冻结前,0.25 mm粒径土壤N2O排放通量比1 cm粒径土壤平均高26.5%;冻结过程中,0.25 mm粒径土壤比1 cm粒径土壤较早达到稳定冻结状态(分别在冻结1 410 min和2 610 min时),并且在稳定冻结状态下,0.25 mm粒径土壤N2O排放通量小于1 cm粒径土壤;融化阶段,0.25 mm粒径土壤比1 cm粒径土壤较早出现N2O排放通量高峰(分别在融化2 670 min和2 790 min时),并且其峰值小于1 cm粒径土样. 1 cm粒径土壤在冻结过程、融化过程和整个冻融过程中,土壤平均N2O排放量分别比0.25 mm粒径土壤多3 952.74、1 512.51和5 465.25 μg m-2,相应增加76.83%、18.65%和41.23%. 建议在土壤冻结前平整土地以减少N2O排放. 图2 参23
Abstract:
The lab-simulated freezing and thawing experiment was conducted to investigate the characteristics of different soil particle sizes (≤1 cm and ≤0.25 mm) affecting the N2O flux from fluvo-aquic soil. The results showed that the N2O flux of 0.25 mm soil increased by 26.5% compared with that of 1 cm soil before soil freezing; the stable frozen state of 0.25 mm soil was earlier than that of 1 cm soil (1 410 min and 2 610 min for freezing, respectively) at freezing stage, and the N2O flux of 0.25 mm was smaller than that of 1 cm soil at the state; the 0.25 mm soil could also reach N2O emission peaks earlier than 1 cm soil at the thawing stage, but the peak values of N2O were mostly smaller than those of 1 cm soil; in the 1 cm soil, the average cumulative soil N2O emissions increased by 3 952.74 (76.83%), 1 512.51 (18.65%) and 5 465.25 μg m-2 (41.23%) compared with those in the 0.25 mm soil in the freezing and thawing processes, and the whole, respectively. It is suggested to level soil before soil freezing in order to reduce N2O emission. Fig 2, Ref 23
