氯化铵一般不单独专门生产,而是和纯碱同时生产,称为“联合制碱法”。它所用的原料是合成氨、三氧化碳、水和食盐。氯化铵用于农业生产,全国各地过去都作了一些试验,增产效果与等氮量硫酸铵差不多,在某种情况下效果更好,因土因作物而异。由于氯化铵本身含氯离子,就不像硫酸铵,尿素适应性那样广,兼之,过去我国这种肥 Ammonium chloride is generally not a separate specialized production, but at the same time and soda production, known as the “joint soda method.” It uses raw materials are ammonia, carbon dioxide, water and salt. Ammonium chloride is used in agricultural production and some tests have been conducted in the past in all parts of the country. The effect of increasing production is similar to that of ammonium sulfate, and in some cases, the effect is better. Soil varies with crops. Since ammonium chloride itself contains chloride ions, it is not as broad as ammonium sulfate or urea. In the past, China’s fertilizer
