遍及各县区的小氮肥厂生产的碳酸氢铵肥料是根据我国的具体情况发展起来的,占我国氮肥使用量的三分之一以上。但是,碳酸氢铵肥料不稳定,在运输、贮存和施用过程中往往引起大量挥发,其利用率仅27%左右。因而,对碳酸氢铵肥料不稳定性的探讨是需要解决的问题。要提高碳酸氢铵肥料的 Ammonium bicarbonate fertilizer, which is produced by small nitrogenous fertilizers throughout the counties and districts, was developed according to the specific conditions of our country and accounted for more than one third of the amount of nitrogen fertilizer used in our country. However, ammonium bicarbonate fertilizers are unstable and often cause large amounts of volatilization during transportation, storage and application, with a utilization rate of only about 27%. Therefore, the discussion on the instability of ammonium bicarbonate fertilizer is a problem to be solved. To raise the ammonium bicarbonate fertilizer
