今年九月,中央有关部门在长沙召开了“全国磷肥、磷矿生产建设会议”。本刊为适应我省开展磷矿粉肥试验、使用和推广工作的需要,特选登了几篇会议的材料,供同志们参考。磷矿粉肥,是近几年来我国各地正在试验使用的一种磷素肥料,它可以直接肥田,又为国家节约了生产过磷酸钙、钙镁磷肥的大量硫酸,焦碳和电力。目前,我国南方不少地区在试验、使用和推广工作上,作了不少工作。为我省开展这方面的工作提供了宝贵经验。
In September this year, the central authorities held a “National Conference on the Production and Construction of Phosphate Fertilizers and Phosphate Rocks” in Changsha. In order to meet the need of our province to carry out the test, use and popularization of phosphate fertilizer and fertilizer, we selected materials of several conferences for your reference. Phosphorite fertilizer is a kind of phosphorus fertilizer that is being tested in various parts of China in recent years. It can directly fertilize fields and save a great deal of sulfuric acid, coke and electricity for producing superphosphate, calcium magnesium phosphate fertilizers for the country. At present, many areas in southern China have done a lot of work in testing, using and promoting the work. It has provided precious experience for our province to carry out this work.
