磷素是植物生长过程中必不可缺少的养料之一。目前我省磷肥的生产量还远远不能满足农业迅速发展的要求。为了迅速发展磷肥生产,当前在我省硫酸供应不足的情况下,我们采用芒硝法搞烧结磷肥试验,扩大磷肥来源,积极解决广大贫下中农的需要。芒硝法烧结磷肥,是一种构溶性磷肥。以磷矿粉,芒硝、煤粉为原料,按一定比例和水混合成型,在高温下烧结制得。产品显中性或弱碱性,不吸潮,不结块,可溶于有机酸而被 Phosphorus is one of the indispensable nutrients in the growth of plants. At present, the production of phosphate fertilizer in our province is far from meeting the requirements of the rapid development of agriculture. In order to rapidly develop the production of phosphate fertilizer, the current shortage of sulfuric acid in our province, we use the Glauber’s salt sintering experiment, expand the source of phosphate fertilizer, and actively address the needs of the majority of poor middle peasants. Glauber salt method sintering phosphate fertilizer, is a structure-soluble phosphate fertilizer. To phosphate rock, Glauber’s salt, coal as raw material, according to a certain percentage of water mixed molding, sintering at high temperature system. Products were neutral or weakly alkaline, non-hygroscopic, non-caking, soluble in organic acids and was
