碳酸氢铵和氨水是我国氮肥的主要品种,占氮肥总产量的70％以上,在农业高产稳产中起到较大作用。这两个氮肥品种都具有生产简便,成本低廉,适宜地方性中小工厂就地生产和施入土壤不残留酸根(即不易使土壤板结——编者)等许多优点,但也具有挥发强的缺点(除了有些单位使用得法可达到50％左右的利用率,一般只有30％左右),它的肥效经常受到施用方法所左右,因此在施用技术上必须十分注意。
Ammonium bicarbonate and ammonia are the main nitrogenous fertilizers in our country, accounting for more than 70% of the total nitrogenous fertilizers, playing a greater role in the high and stable agricultural yield. Both of these nitrogenous fertilizer varieties have many advantages such as ease of production, low cost, suitable for local small and medium-sized factories in situ production and application of non-residual acid soils (ie, soil compaction - editor), but also have the disadvantage of strong volatility In addition to the use of some units can achieve about 50% utilization, generally only about 30%), its efficiency is often affected by the application method, so the application of technology must pay great attention.
