摘　　要：采用与缓释反方向的理化促释技术,于常温、常压条件下,在磷、镁、钾3种矿物肥源中添加质量分数5%～10%的活化剂(CS),制得粉体促释磷、镁、钾肥,促进养分释放。试验表明:促释技术可提高矿物肥源的水溶性养分含量和肥效,提高作物产量,大大拓宽制肥矿物资源,具有明显的节资、节能作用。The physico-chemical release-promotion technology is adopted, which is opposite to slow-release. Under normal temperature and pressure conditions an activator （CS） is added at a mass fraction of 5% -10% to three mineral fertilizer sources of phosphorus, magnesium and potassium, to give powdery release-promotion fertilizers to accelerate nutrient release. Experiments show that the release-promotion technology is able to increase the water-soluble nutrient content and fertilizer effect, enhancing the crop yield, greatly expanding the mineral resources for fertilizer manufacture, and resulting in remarkable saving in resources and energy.
