氯化铵是氨态氮肥的一种,它是联合制碱工业的副产品。含氮量较硫酸铵高5%左右,肥效与等氮量的尿素、硫铵大致相当。从50年代起,日本对氯化铵做了大量的肥效试验和对土壤条件影响的研究;我国就将氯化铵列入全国化肥网试验。结果证明氯化铵的肥效均与硫铵近似。在对土壤氯离子残留试验中,有的连续13年施用均无氯根残留,只有粘质土壤才有少量氯根残留。我市天津碱厂年产氯化铵15万吨。过去远销江南,换回少量其它氮素指标。如能就地应用氯化铵,不仅能补救我市氮肥不足又
Ammonium chloride is a form of ammonium nitrogen fertilizer, which is a by-product of the combined alkali industry. Nitrogen content is about 5% higher than ammonium sulfate, fertilizer and other nitrogen, urea, ammonium sulfate roughly the same. Since the 1950s, Japan has done a lot of fertilizer ammonium chloride test and the impact of soil conditions study; China will ammonium chloride included in the national fertilizer net test. The results show that ammonium chloride fertilizer and ammonium sulfate are similar. In the soil chloride ion residual test, some of the 13 consecutive years of application of chloride-free residual, only a small amount of clay soil residual chloride. Tianjin Soda Factory annual output of ammonium chloride 150,000 tons. In the past, it was exported to Jiangnan and returned a few other nitrogen indicators. If the application of ammonium chloride in situ, not only can help remedy the shortage of nitrogen fertilizer in our city
