一种提升龙眼品质的复合肥料及其制备方法

本发明涉及农业肥料领域，公开了一种提升龙眼品质的复合肥料及其制备方法，包括尿素、磷酸一铵、硫酸钾、腐熟有机载体、功能复合菌剂、腐植酸钾、七水合硫酸锌、硼酸和工业级甘油。其制备过程将无机原料与部分腐熟有机载体预混，利用由腐植酸钾、七水合硫酸锌、硼酸与甘油反应生成的热态复合络合浆料对其进行喷涂包裹，经降水处理后，再与剩余的腐熟有机载体和功能复合菌剂混合并冷挤压造粒。通过该分层结构在无机盐与功能菌之间形成物理隔离，降低盐胁迫对菌剂存活的影响；同时使锌元素以腐植酸络合态存在，使硼元素参与硼酸酯动态络合结构，减少微量元素在肥料制备、贮存和施入土壤后的固定损失，使养分释放过程更适应龙眼生育期需肥规律。
