| 摘 要： | 通过室外模拟田间培养试验,研究不同硝化抑制剂及其复配后的硝化抑制效果。结果表明:不同硝化抑制剂,明显抑制了NH4+-N向NO3--N的转化。硝化抑制剂1-甲胺酰基-3,5-二甲基吡唑(CMP)有明显的抑制效果,优于4氨基-1,2,4-三唑盐酸盐(ATC)、双氰胺(DCD);硝化抑制剂CMP与DCD复配的抑制效果显著,硝化抑制率为35.6%。为了结合生产实际获得最优性价比,在硝化抑制剂复配比率方面尚需进一步研究。

| Abstract: | Urease inhibitors and nitrification inhibitors are used for slowing the hydrolysis of urea and ammonium nitrogen of soil to sell the conversion of N.In this experiment,brown earth was used as a substrate,in the same amount of urease inhibitor,under simulated field cultivation experiments conducted outdoors.The results showed that the application of nitrification inhibitors significantly inhibited the NH4+-N to NO3——N conversion of CMP with the nitrification inhibitor DCD fertilizer effect most significantly.Followed by nitrification inhibitor CMP with significant inhibition rate of 35.6%;ATC here showed no significant effect,but there were also some inhibitory effect. |
