碳酸氢铵(简称碳铵)是我国农业生产上的主要氮肥品种,约占氮肥总用量的55％,对促进我国农业生产起很大的作用,但碳铵具有易挥发,肥效差等缺点,为了使碳铵得到合理的施用,我们在1982年研究的基础上,1983年着重比较碳铵粉剂和粒剂的试验效果。 Ammonium bicarbonate (referred to as ammonium bicarbonate) is China’s agricultural production of the main nitrogen fertilizer varieties, accounting for about 55% of the total nitrogen fertilizer, to promote China’s agricultural production play a significant role, but the ammonium bicarbonate with volatile, poor fertilizer and other shortcomings, In order to make ammonium bicarbonate be rationally applied, based on the 1982 study, we focused on comparing the test results of ammonium carbon powder and granule in 1983.
