碳酸氢铵是我国在1958年大跃进年代发展起来的一种新型氮肥品种。碳铵具有生产过程简单、基建投资少、建厂快、成本低等特点,但缺点是含氮量较低(17％左右)容易吸潮结块和分解挥发,贮藏运输施用不当会造成氮素损失,降低肥效。碳铵在撒施表土的情况下,其利用率不到30％。 Ammonium bicarbonate is a new type of nitrogen fertilizer developed in our country during the Great Leap Forward in 1958. Ammonium bicarbonate has the characteristics of simple production process, less investment in infrastructure, fast construction and low cost. However, the disadvantage is that nitrogen content is low (about 17%), it is easy to absorb moisture and agglomerate and decompose and volatilize, and improper storage and transportation can cause nitrogen Loss, reduce fertilizer. Ammonium bicarbonate in the case of spreading topsoil, its utilization rate of less than 30%.
