氯化铵是铵态氮肥的一种。它是联合制碱工业的副产品,含氮量较硫铵高5％左右。肥效与等氮量的尿素、硫铵大致相当。我市天津碱厂年产氯化铵12～15万吨,过去远销江南,换回少量其它氮素指标,每年需贴补运费近百万元,又造成铁路运输紧张。近年来南方各省不再换肥,而我市氮肥又严重亏缺,如能应用地产氯化铵,不仅能补救我市氮肥不足,又可缓和铁路运输环节。同时,氯化铵价格便宜,可大幅度降低农业生产成本,提高社会和经济效益。但氯化铵含大量氯离子,在
Ammonium chloride is ammonium nitrogen fertilizer. It is a by-product of the combined alkali industry, with nitrogen content about 5% higher than ammonium sulfate. Fertilizer efficiency and equal nitrogen urea, ammonium sulfate roughly the same. The annual output of ammonium chloride in our city Tianjin 12 to 150,000 tons, in the past exported to Jiangnan, in exchange for a small amount of other nitrogen targets, annual subsidies freight nearly 1 million yuan, but also cause rail transport tensions. In recent years, the southern provinces no longer for fertilizer, and nitrogen deficiency in our city a serious shortage, such as the application of real estate ammonium chloride, not only to help the city lack of nitrogen, but also ease the link of railway transportation. At the same time, the price of ammonium chloride is cheap, which can greatly reduce agricultural production costs and increase social and economic benefits. However, ammonium chloride contains a large amount of chloride ions
