硫脲既是一种硝化抑制剂也是一种脲酶抑制剂。国外的一些研究表明,硫脲与尿素或硝铵尿素(UAN)配施能有效抑制土壤中尿素的水解、减少NH3挥发损失和延缓氮素的矿化过程,同时促进作物生长、增加作物产量。
Thiourea is both a nitrification inhibitor and a urease inhibitor. Some foreign studies show that urea and urea or ammonium nitrate urea (UAN) combination can effectively inhibit the hydrolysis of urea in the soil to reduce the loss of NH3 volatilization and delay the mineralization of nitrogen, while promoting crop growth and increase crop yield.
