| 摘 要： | 通过室内培养试验,研究5种改性尿素对土壤N2O排放的效果,结果表明:当旱田土壤含水量较低(23%)时,NI(尿素 硝化抑制剂)处理的土壤NO排放效果最好,其次为FL(尿素 1.0?D 0.3%HQ)。当旱田土壤含水量较高(34%)时,FL处理的土壤N2O排放效果最好,其次为处理NI;当稻田土壤处于淹水状态时,Meister(包被尿素)处理的土壤N2O排放效果最好,其次为处理FL。该试验结果对于选取优良改性尿素进行田间试验、进一步探讨改良尿素对土壤N2O的排放效果具有指导意义。 |

| Abstract: | In indoor culture experiments,the effects of five modified urea products on the N2O emission from soil are studied.The results showed that when the water content of upland soil was 23%,the effects of NI(urea nitrification inhibitor) treatment on reducing N2O emission from soil was the best and the next was FL(urea HQ plus DCD) treatment.When the water content of upland soil was 34%,the effect of FL treatment on reducing N2O emission was the best and the next was NI treatment.When rice paddy was flooded,the effects of Meister(coated urea) treatment on reducing N2O emission from soil was the best,then was FL treatment.These results would play a guidance role in selecting better modified urea in field experiments to further study the effects of modified urea on N2O emission from soil. |
