| 摘 要： | 通过网室水稻盆栽试验,探讨几种有机无机肥混施方式对CH4排放的影响.结果表明,水稻土CH4排放有明显的逐日变化,在水稻分蘖末期和抽穗前期出现CH4排放高峰.不同有机无机肥混施方式对CH4排放的影响明显,最高和最低的CH4排放量分别为8.12和5.72g·m-2,两者相差42.0%.粒状有机无机复肥的CH4排放量高,但稻谷产量也高,因而其单位稻谷产量的CH4排放量反而较低.

| Abstract: | Pot experiment with a paddy soil was conducted to study the effect of several combined applications of organic and inorganic fertilizers on CH4 emission.The results indicate that the CH4 emission showed a pronounced diurnal variation,and the peaks occured at late tillering and early heading stages.Different combined applications of organic and inorganic fertilizers showed an obvious effect on CH4 emission,and the highest and lowest emissions were 8.12 and 5.72 g·m-2 respectively,with a 42% difference.Granulated organic inorganic fertilizer induced a high CH4 emission,but the rice yield was also high.Instead,the CH4 emission of per unit rice yield was lower. |
