摘要
采用室内培养实验的方法,以不加抑制剂的尿素作为对照,对比研究DMPP及它的同分异构体3,5-二甲基吡唑磷酸盐作为硝化抑制剂对尿素氮在土壤中转化的影响。结果表明,3,5-二甲基吡唑磷酸盐具有一定的硝化抑制作用。在培养期间,施加3,5-二甲基吡唑磷酸盐的土壤中硝态氮的含量一周后始终低于对照,铵态氮的含量一周后始终高于对照。但在培养试验中后期(三周以后),3,5-二甲基吡哇磷酸盐的硝化抑制效果劣于DMPP。3,5-二甲基吡唑磷酸盐能否作为新型硝化抑制剂,还要对它的生理、生态效应等进行进一步的研究。
Based on the method of incubation test by contrasting the urea of without nitrification inhibitor added, this paper compared the effect of DMPP and its isomers 3,5 - Dimethylpyrazole phosphate as nitrification inhibitors on the transform of urea nitrogen in soil. The results showed that 3,5- Dimethylpyrazole phosphate has definite role of nitrification inhibition. During the period of cultivation, a week later the content of soil nitrate nitrogen by adding 3,5 - Dim- ethylpyrazole phosphate is all along lower than that of contrast, and the content of soil anunonium nitrogen is all along higher than that of contrast. But in the later period （ three weeks later）, the nitrification inhibiting effect of 3, 5 - Dimethylpyrazole phosphate as a nitrification inhibitor is inferior than DMPP. 3,5 - Dimethypyrazole phosphate can or not become a new nitrification inhibiior, we should do more research on its efficiency of physiology and ecology.
