近十几年,由于高浓度磷肥的发展,我国钙镁磷肥生产处于下滑的状况。根据钙镁磷肥含有多种植物所需营养元素,结合我国有大量适合生产钙镁磷肥的高硅、高镁中低品位磷矿,以及目前我国土壤对中微量元素的需求,钙镁磷肥的沙性作为复混肥生产的磷源可减轻肥料的黏性等优势,提出我国应重视发展钙镁磷肥。
In recent ten years, due to the development of high concentration phosphate fertilizer, the production of calcium magnesium phosphate fertilizer in our country is in decline. According to calcium magnesium phosphate contains nutrients required by a variety of plants, combined with a large number of high-silicon, high-magnesium low-grade phosphate rock in our country for the production of calcium magnesium phosphate, and the current needs of our soil for trace elements, calcium magnesium phosphate fertilizer As the phosphorus source of compound fertilizer, it can reduce the stickiness of fertilizer and so on. It is proposed that our country should attach importance to the development of calcium, magnesium and phosphate fertilizers.
