磷酸铵是一种化学肥料,它含有氮、磷两种作物最需要的营养元素。 通常制造磷酸铵,是将硫酸加到磷矿粉中,先生成磷酸,然后再通氨气制成磷酸铵。按照这种方法制造磷酸铵,投资很大,而且设备也比较复杂。 去年4月初,我们随湖北省委检查团到宣恩工作期间,在宣恩县副县长赵文杰同志亲自领导,铁厂玻硫磺厂职工同志大力协助下,我们以硫磺脚渣和骨头为原料,用土办法制成了磷酸铵。
Ammonium phosphate is a chemical fertilizer that contains the nutrients that are most needed for both nitrogen and phosphorus crops. Usually made of ammonium phosphate, sulfuric acid is added to the phosphate rock, the first into a phosphoric acid, and then pass through ammonia to make ammonium phosphate. In accordance with this method of manufacturing ammonium phosphate, a great investment, but also more complicated equipment. Last year in early April, we went to Xuanyen with the inspection team of Hubei Provincial Party Committee during the work, accompanied by Comrade Zhao Wenjie, the deputy magistrate of Xuan’en County, and with the great assistance of staff and workers of Glassworks Sulfur Factory, we used sulfur feet and bones as raw materials, Soil made of ammonium phosphate.
