补充资料:氮肥增效剂(nitrogen fertilizer synergist)
分子式:
CAS号:

性质:又称氮肥增效剂(nitrogen fertilizer synergist)。加入铵态氮肥中以抑制土壤内亚硝酸细菌对铵态氮的硝化,从而减少铵态氮转化为硝态氮而流失所用的添加剂。硝化抑制剂除有减少氮肥损失、提高氮肥利用率而增加产量的作用外,还可降低农作物中亚硝酸盐含量,提高农作物品质,减少施肥量过高时对土壤、地下水和环境的污染。但在某些情况下,硝化抑制剂对作物的增产效果不够稳定。硝化抑制剂有2-氯-6-(三氯甲苯)吡啶(又称西吡),代号为(P)、脒基硫脲(ASU)、双氰胺(DCD)、2-甲基-4,6-双(三氯甲苯)均三嗪(MDCT)、2-磺胺噻唑(ST)等。
