一、我省磷肥工业概况解放前,我省只有南京化学工业公司氮肥厂(永利宁厂),年产氮肥1.8万吨,到1958年也只有23.37万吨,同时生产磷肥2.09万吨。随着工业生产的不断发展,到1981年底,全省已建成县级以上磷肥厂56个,磷肥生产能力为140万吨(折纯24.04万吨),历年磷肥产量及品种见表1。
I. Overview of phosphate fertilizer industry in our province Before the liberation, only Nanjing Chemical Industry Company’s nitrogen fertilizer plant (Yongli Ning Plant) in our province produced 18,000 tons of nitrogen fertilizer annually. By 1958, it was only 237,700 tons. At the same time, it produced 20,900 tons of phosphate fertilizer. With the continuous development of industrial production, by the end of 1981, 56 phosphate fertilizer plants above the county level had been established in the province, and the production capacity of phosphate fertilizer was 1.4 million tons (240,400 tons). Table 1 shows the output and varieties of phosphate fertilizers over the years.
