氮肥增效剂国外称氮肥硝化抑制剂或称土址处理剂,它具有选择性的抑制硝化微生物的作用,是保持土址中铵态氮、防止氮肥流失、提高氮肥肥效、促进作物生长,从而使作物增产的一类化学物质。据国内外报导,按氮肥含氮量加入1～3％的氮肥增效剂,就可以使粮食和其他作物平均增产10％左右。 Nitrogen fertilizer synergist abroad known as nitrification inhibitor or soil treatment agent, which has the selective inhibition of the role of nitrifying microorganisms, is to maintain the ammonium nitrogen in the site, to prevent nitrogen loss, improve nitrogen fertilizer efficiency and promote crop growth, thus A class of chemicals that increase crop production. According to reports both at home and abroad, adding 1 to 3 percent of nitrogenous fertilizer synergist according to the nitrogenous nitrogen content can increase the average yield of grain and other crops by about 10%.
