目前土法生产腐疽酸铵(煤化肥)大都是用30斤氨水(或15～25斤碳铵)与100斤风化煤粉进行拌合熟化而成。有的社队甚至没有一定的配比,生产出来的腐殖酸铵气味很大,这样既使氨水(或碳铵)与风化煤粉的比例不适当,氨过量太多,反应不完,造成氨的大量损失,又使产品成本增高,对于保证产品质量也是不利的。 At present, indigenous production of fermented ammonium sulfate (coal fertilizer) are mostly 30 kg of ammonia (or 15 to 25 kg of ammonium bicarbonate) and 100 kg of weathered pulverized coal mixing and aging made. Some communes and teams do not even have a certain ratio, produced a great smell of ammonium humic, so that even ammonia (or ammonium bicarbonate) and the proportion of weathered coal inappropriate, too much ammonia, the reaction, resulting in A large number of ammonia losses, but also to increase product costs, to ensure product quality is also unfavorable.
