| 摘 要： | 研究了石灰氮对尿素的增效作用。结果表明，石灰氮对硝化作用有明显的抑制效应，并能抑制脲酶活性，延缓尿素水解。石灰氮作为氮肥增效剂添加到尿素中，可提高尿素氮的利用率，使青菜产量增加，硝酸盐含量降低。其添加量以尿素量的１０％－２０％为宜。

| Abstract: | Incubation and pot experiments were carried out to study the synergetic effects of lime-nitrogen on urea. The results showed that the effect of lime-nitrogen on the inhibition of ni-trification is obvious, and it inhibited urease activity and decreased the hydrolytic rate of urea. Ap-plying urea supplemented with lime-nitrogen could raise the use efficiency of urea, increase the yields of vegetables and reduce contents of nitrate.The suitable application rate df lime-nitrogen should be 10%-20%of the total amount of urea. |
