| 摘 要： | 为进一步完善蔬菜硝酸盐污染的调控技术体系，采用好气培养法研究了新型硝化抑制剂3，4-二甲基吡唑磷酸盐(DMPP)对菜园土壤NH4^ -N，NO3^--N含量的影响。结果表明，在培养过程中，土壤NH4^ -N含量呈现出先减少后略有升高的变化趋势，而NO3^--N含量呈现出先升高后减少的变化趋势，DMPP处理的土壤中NH4^ -N含量高于硫硝镀(ASN)处理，NO3^--N含量则相反。

| Abstract: | This paper probes into the NH 4 + N, NO 3 - N concentration dynamics on DMPP (3,4 dimethylpyrazole phosphate) in vegetable soils under fertilized condition with aerobic cultivation. The results show that there is a tendency that NH 4 + N decreases in the prophase, and then increases a little in the anaphase. There is a tendency that NO 3 - N increases in the prophase and then in the anaphase. NH 4 + N concentration is higher in DMPP treatment than in ASN treatment, whereas NO 3 - N concentration reverses. |
