施入农田的各种氮肥由于土壤中硝化微生物的破坏,造成严重损失,近年来已引起各国普遍重视,对如何抑制土壤硝化微生物的活动、减少氮肥损失,提高氮肥利用率,成为重要的研究课题。氮肥增效剂国外称为硝化抑制剂(Nitrfication inhibitor),是一种在一定时间内能够选择性抑制土壤中亚硝化毛杆菌(Nitrosomonos)的活动,减少氮肥损失,提高氮肥利用率的化学助剂。氮肥混施适量的氮肥增效剂可以提高作物产量。因此,六十年代以来氮肥增效剂的研制和使用有较大的发展。我国氮肥增效剂的研制和使用虽然时间不长,但是发展十
Various nitrogenous fertilizers applied to farmland have caused serious losses due to the destruction of nitrifying microorganisms in the soil. In recent years, they have drawn widespread attention in various countries. They have become an important research topic on how to suppress the activities of soil nitrifying microorganisms, reduce the loss of nitrogenous fertilizers and increase the utilization rate of nitrogenous fertilizers . Nitrogen fertilizer synergist abroad known as the nitrification inhibitor (Nitrfication inhibitor), is a kind of in a certain period of time can selectively inhibit soil nitrosomonas (Nitrosomonos) activity, reduce nitrogen loss, improve nitrogen fertilizer chemical additives . Nitrogen fertilizer mix appropriate amount of nitrogen fertilizer synergist can improve crop yields. Therefore, since the sixties nitrogen fertilizer synergist development and use of greater development. China’s nitrogen fertilizer synergist development and use of time though not long, but the development of ten
