摘要 为研究不同形态吡唑类硝化抑制剂施入土壤后的转化过程,以3-甲基吡唑(MP)及其衍生物的紫外吸收光谱为基础,分别进行了1-甲氨酰基-3-甲基吡唑(CMP)、1-羟甲基-3-甲基吡唑(HMP)和3-甲基吡唑磷酸盐(MPP)在土壤中的水解反应试验。结果表明,CMP、HMP和MPP3种吡唑类硝化抑制剂添加到土壤中后,均会水解为MP,通过甲胺酰化、羟甲基化和中和反应处理吡唑类化合物,只能改变其存在形态和物理特征,并不能提高吡唑类化合物的硝化抑制效果。土壤中存在的能催化C—N键水解的微生物或酶可能会使水解反应加速。 In order to study the translation process of pyrazole nitrification inhibitors in different forms applied in soil,based on the determination of ultraviolet absorption spectra of 3-methylpyrazole(MP) and it derivations,the author studied the hydrolyzation of 1-carboxamide-3-methylpyrazole(CMP),1-hydroxymethyl-3-methylpyrazole(HMP) and 3-methylpyrazole phosphate(MPP) in soil,respectively.The results showed that three nitrification inhibitors CMP,HMP and MPP,would hydrolyzed to MP when applied to soil.The neutralization and introduction of carboxamide or hydroxymethyl would unchanged the effect of MP,but only changed the form and physical characteristics.The microorganism and enzyme in soil which catalyzed hydrolyzation of C—N might increase the hydrolyzation.
