| 摘 要： | 水田土壤施用涂层尿素抑制氮素挥发损失的研究结果表明，涂尿素素肥料在全层混施，8cm深施和表面撒施3种施肥方式下均有抑制NH3和NOx挥发损失的作用，涂层尿素与普通尿素相比，表面撒施降低氮素（NH3＋NOx)挥发损失率达32．8％，8cm深施降低氮素（NH3＋NOx)挥发失率达19．9％，全层混施降低氮素（NH3＋NOx)挥发损失率达6．9％。

| Abstract: | Inhibiting effect of nitrogenous volatile loss was studied in paddy soil. The comparison between the coated urea and the common urea was made. The result showed that surface broadcasting of coated urea can reduce the volatilization loss of nitrogen (NH3 NOX) reaching 32.8%, whole layer fertilization with 8cm deep can reduce the volatilization loss of nitrogen (NH3 NOX) reaching 19.9%, whole layer fertilization can reduce the volatilization loss of nitrogen (NH3 NOX) reaching 6.9%. |
