| 摘 要： | 综述了免耕方式下农田土壤中3种主要温室气体(CO2、N2O和CH4)的排放情况及影响因素。分析发现,这些温室气体的排放受到诸多因子的影响,如免耕农作持续时间、土壤特性、秸秆(种类、粉碎长短和施用方式)、降水和土壤温度等等。大多数研究都认为,免耕方式下CO2和CH4的释放有所降低,N2O的释放会加强,但这种结果并不是不变的,它会随着影响因素的变化而变化,有时甚至出现相反的结果。因此,免耕方式下,温室气体的排放情况是由不同免耕地区的环境条件决定的,只有结合当地实际情况才能对温室气体的排放做出正确的评价。最后指出了目前研究的不足,并对今后的研究提出了展望。

| Abstract: | The emission of three greenhouse gases(CO2,N2O and CH4) in soil under the no-tillage cultivation was studied in this paper based on recent advances.The result showed that the emission of these gases were influenced by many factors,such as no-tillage cultivation duration,the characteristic of soil,residue,precipitation,soil temperature and so on.Most studies considered that the emission of CO2 and CH4 would decline,while N2O emission would increase in no-tillage soil.But this conclusion is not correct in any... |
