土壤脲酶抑制剂和硝化抑制剂的研究进展

氮素是农作物生长必不可少的元素，其对促进农作物生长，提高产量方面起到了不可忽视的作用。所以，土壤中氮肥的施用成为控制高产的主要因素。但是随着氮肥施用量的增加，土壤过多累积的硝态氮又导致了环境污染方面的问题。为了解决这种污染问题，许多学者在对脲酶抑制剂和硝化抑制剂的研究上取得了很好的进展，利用脲酶抑制剂和硝化抑制剂可以很好的抑制土壤中铵态氮的硝化作用，控制硝态氮的大量积累所导致的环境污染。

Advance of Research on Urease Inhibitor and Nitrification Inhibitor in Soil

Nitrogen is essential to the plant. It makes important effects which promote the growth of the plant, increase the yield. So the nitrogen fertilizer became one of the limiting factors which control the yield. Howerver,if too much nitrogen fertilizer is applied into the soil, it will result some problems. Nitrate residue in the soil produces many problems to the environment. So many scientists made some good processes on the urease inhibitor and nitrification inhibitor. They used the inhibitors to reduce the pollution which the nitrate residue existed in the soil.
