磷肥在我省农业生产中具有重要作用,已为生产实践所证实。但当前,过磷酸钙和钙镁磷肥工业生产数量不能满足农业生产上的需要。因而开辟新的磷肥来源,就成为新的突出矛盾。生产磷矿粉肥,既不用酸,又不用焦,加工简单,为大量的磷源开辟了新途径。我省每年有较多量摩洛哥进口的磷矿粉,这种磷矿粉为细小颗粒及粉末状物质的混和物,含有较多的枸溶性磷酸,在缺磷的土壤上直接施用,作物
Phosphate fertilizer in agriculture in our province has an important role, has been confirmed for the production practice. But at present, the amount of industrial production of superphosphate and calcium magnesium phosphate can not meet the needs of agricultural production. Thus opening up a new source of phosphate fertilizer, it has become the new prominent contradictions. Production of phosphate rock fertilizer, neither acid, no coke, simple processing, opened up a new way for a large number of phosphorus sources. There are a large amount of phosphate rock powder imported into our province each year. This kind of phosphate rock powder is a mixture of fine particles and powdery substances. It contains more citric acid soluble phosphate and is applied directly on the phosphorus-deficient soil. Crops
