碳酸氢铵(简称碳铵)是我区生产的氮肥主要品种,它含有铵和碳酸都能被作物吸收利用,不残留对土壤和作物生长的有害物质。但是碳铵性质很不稳定,在接触空气特别在较高温情况下,容易分解产生二氧化碳、氨气和水。因此如何做到合理贮藏和施用,减少肥分损失,提高利用率是当前生产上迫切需要解决的问题。现将我们试验及调查的结果总结如下。一、不同贮藏条件下碳按挥发损失的测定用50毫升烧杯
Ammonium bicarbonate (referred to as ammonium bicarbonate) is the main nitrogenous fertilizer produced in our district. It contains ammonium and carbonic acid which can be absorbed and used by crops without leaving harmful substances on soil and crop growth. However, the ammonium bicarbonate is very unstable in nature and is easily decomposed to produce carbon dioxide, ammonia and water when exposed to air, especially at higher temperatures. Therefore, how to achieve reasonable storage and application, to reduce the loss of fertilizer, and to improve the utilization rate are urgent problems to be solved in the current production. The results of our tests and investigations are summarized as follows. First, under different storage conditions carbon loss by the determination of 50 ml beaker
