| 摘 要： | 通过室内培养试验,研究了3种吡唑类硝化抑制剂CMP(1-甲氨甲酰-3-甲基吡唑);DMPP(3,4-二甲基吡唑磷酸盐);DMP(3,5-二甲基吡唑)在黑土上的抑制效果。其结果表明:在相同质量浓度下,3种吡唑类硝化抑制剂的硝化抑制顺序为CMP>DMPP>DMP。CMP是一种高效的硝化抑制剂,0.1%尿素添加量下强烈抑制了铵态氮的转化。DMP的抑制效果最差,在整个培养的第40 d,硝态氮的含量甚至超过了CK。

| Abstract: | With aerobic incubation test,the effects of three different compounds(1-carboxamide-3-methylpyrazole,3,4-dimethylpyrazole phosphate,3,5-dimethylpyrazole) were studied.The results indicated that when the dosage was 0.1% of applied urea,the efficiency of the nitrification inhibitory was CMP>DMPP>DMP.CMP was a higher nitrification inhibitor among them.DMP showed a lower efficiency and the concentration of NO3——N at the 40th day was higher than the control. |
