碳酸氢铵(以下简称碳铵)是我国一九五八年大跃进年代发展起来的一种新型氮肥它具有生产过程简单,基建投资少,建厂快成本低等特点。但是,这种化肥也存在一些缺点和不足之处,如含氮量较低(17％左右),容易吸潮结块和分解挥发,以改造成氮素损失,降低肥效。使用不当还会引起烧苗,碳铵在撒施表土情况下,其利用率不到30％,因此,通过各种途径提高碳铵的肥效是当前迫切需要解决的问题。
Ammonium bicarbonate (hereinafter referred to as ammonium bicarbonate) is a new type of nitrogen fertilizer developed in China during the Great Leap Forward in 1958. It has the characteristics of simple production process, less capital construction investment and low cost of construction. However, this fertilizer also has some shortcomings and shortcomings, such as low nitrogen content (about 17%), easy to absorb moisture caking and decomposition of volatile in order to transform into nitrogen loss and reduce fertilizer efficiency. Improper use can also cause burning seedlings, ammonium bicarbonate in the application of topsoil case, the utilization rate of less than 30%, therefore, through a variety of ways to improve the efficiency of ammonium bicarbonate is an urgent need to be addressed.
