长效碳酸氢铵在农业上的应用由于碳酸氢铵生产工艺和设备都不复杂，原料丰富，产品就地使用，不需长途运输，因此发展很快。但是碳酸氢铵存在一些缺点，如含氮量低．只有１７％的氮；易分解，挥发损失大；氮利用率低，一般只有２５％左右：肥效期短，平均只有３５天左右：... Long-acting ammonium bicarbonate in agricultural applications Since ammonium bicarbonate production process and equipment are not complicated, rich in raw materials, products used locally, without long-distance transport, so the rapid development. However, ammonium bicarbonate has some disadvantages, such as low nitrogen content. Only 17% of nitrogen; easy to decompose, volatile loss; low nitrogen utilization, generally only about 25%: short effective period, with an average of only 35 days or so ...
