| 摘要: |
| 采用乙炔抑制法,利用气相色谱仪测定土壤中 N2O 释放量,并研究其影响因素。测定结果表明:温度、湿度及通气状况对土壤中 N2O 释放量的影响具有显著差异,并且交互作用的差异也达到极显著水平。由温度、湿度与土壤中 N2O 最大释放量的逐步回归方程式看出,在嫌气条件下温度对反硝化作用的影响比湿度的影响较为显著,而好气条件下湿度的影响要比温度的影响显著。 |

| Abstract: |
| Our experiment indicated that the denitrification in soil were affected by the temperature, soil moisture and aeration status.The amount of N_2O in different treatments were measured in the pres- ence of C_2H_2 by gas chromatography. The results showed that the temperature,soil moisture and aeration had a great influences on the N_2O emission by denitrification.Their mutual effects were also significant. It was illustrated by the stewise regression that effect of temperature on the rate of denitrification i... |
