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。如贮藏和施用方法不当,肥料的含氮量就会挥发,造成浪费损

Ammonium bicarbonate (referred to as ammonium bicarbonate), is the main nitrogenous fertilizer produced in our region, which contains ammonium and carbonic acid, can be absorbed by crops. No residues of soil and crop growth of harmful substances. However, the ammonium bicarbonate is very unstable in nature and readily decomposes when exposed to air, especially at higher temperatures, to produce carbon dioxide, ammonia and water. If improper storage and application methods, the nitrogen content of the fertilizer will be volatile, resulting in wastage
