| 摘 要： | 为了研究包膜尿素对水田土壤排放NH3、NOx和CO2的影响,采用水稻盆栽的方法,探讨了在水稻不同生育期内不同种类包膜尿素对水田土壤排放NH3、NOx和CO2的影响。结果表明,包膜尿素处理对水田土壤排放NH3、NOx和CO2均具有抑制作用,与普通尿素相比,包膜尿素LP40、LPSS、BB、SC60 NH3的挥发总量降低了5.4%~19.3%,NOx的挥发总量降低了8.1%~23.4%,CO2的挥发总量降低了1.6%~13.0%;施用包膜尿素能够抑制水田土壤NH3、NOx和CO2的排放。

| Abstract: | In order to research the effect of coated urea on NH3,NOx and CO2 emissions in paddy soil,a pot experiment was conducted.We investigated the effect of different kinds of coated urea on NH3,NOx and CO2 emissions during the different growth stages of rice.Results showed that coated urea had a inhibit effect on NH3,NOx,CO2 emissions in paddy soil.Coated urea of LP40,LPSS,BB and SC60 could decrease the NH3,NOx and CO2 emissions for 5.4%~19.3%,8.1%~23.4% and 1.6%~13.0%,respectively.The application of coated urea could decrease NH3,NOx and CO2 emissions in paddy soil. |
