碳酸氢铵(简称碳铵)是一种挥发性很强的肥料,在我省石灰性土壤上(我省平原地区均为石灰性土壤)撒施,其肥料利用率很低,一般低于30％。为了提高碳铵的肥效,采用深施覆土的办法是很有效的。但是由于碳铵是粉状(小结晶),不便深施,工效低,劳动强度大。为了进一步提高深施效果,我国很多地区研究推广碳铵粒(球)肥深施,取得了很好的增产效果。碳铵可直接压粒,也可加入草炭、褐煤等制成球肥。尤其是将碳铵直接压制成粒
Ammonium bicarbonate (referred to as ammonium bicarbonate) is a highly volatile fertilizer, calcareous soil in the province (the plains of our province are calcareous soil) spreading, the fertilizer utilization rate is very low, generally less than 30 %. In order to improve the efficiency of ammonium bicarbonate, the use of deep overburden method is very effective. However, due to ammonium bicarbonate is a powder (small crystals), inconvenience Shen Shi, work efficiency is low, labor-intensive. In order to further enhance the effect of deep application, many areas in our country to promote the research and application of ammonium bicarbonate (ball) fertilizer, and achieved good yield. Ammonium bicarbonate can be directly pressure tablets, can also be added peat, lignite and other made of fertilizer. In particular, ammonium bicarbonate is pressed directly into granules
