Microencapsulation soil conditioner and preparation method thereof

The invention relates to a microencapsulation soil conditioner and a preparation method thereof. The microencapsulation soil conditioner is composed of ion modified natural clinoptilolite and acidic modified gelatin which is coated on the outer surface of the ion modified natural clinoptilolite and forms a capsule structure. The preparation method comprises the following steps: modifying zeolite with NH4Cl and CaCl2 solution; utilizing borax to modify gelatin; adding the modified zeolite into ethyl alcohol and mixing till the mixture is uniform; adding the modified gelatin solution into the mixture while stirring; removing ethyl alcohol by evaporation; freeze-drying, thereby acquiring the microencapsulation soil conditioner. Compared with the prior art, the microencapsulation soil conditioner has the advantages that all the components are environment-friendly, no problem of damaging or polluting environment exists and the microencapsulation soil conditioner is high in stability. 本发明涉及一种微胶囊化土壤调理剂及其制备方法，土壤调理剂由离
