Abstract本发明属于肥料领域,具体涉及一种以无机肥料为核心的新型双包膜球形肥料的制备方法。将粘结剂、无机包膜层和有机无机复合包膜层依次包裹肥芯,得到双包膜球形肥料;所述无机包膜层为按重量份数计,石膏15-17份、重钙5-6份、灰钙粉2-3份和粘结剂5-8份组成;所述有机无机复合包膜层为按重量份数计,棉秆腐熟物25-30份、淀粉5-10份、重钙10-15份、灰钙粉5-10份、石膏5-7份和粘结剂14-20份组成。本发明以天然有机物和无机矿物为主原料,通过多重包膜工艺,研制大颗粒球形包膜肥料。肥芯为作物提供了营养元素,有机包膜层为改良土壤性状提供了条件,通过矿物包膜和天然有机物包膜可以较大程度的提高肥效利用。
