Summary:The invention relates to a slow-release plant nutrition additive and a preparation method thereof. The slow-release plant nutrition additive is prepared from 45-88.9% of medium-trace-element-containing substances, 1-10% of filler, 0.1-5% of adhesive and 10-40% of vegetable oil. The preparation method comprises the following steps: firstly, dissolving the adhesive in a solvent, and then adding a certain mass of vegetable oil to obtain a vegetable oil emulsion; and mixing the vegetable oil emulsion obtained in the previous step, the medium-trace-element-containing substances and the filler, anduniformly stirring to obtain the slow-release plant nutrition additive. The production process is simple, the content of various nutrients in the prepared slow-release plant nutrition additive is highand complete, and the medium trace elements required by crops are met. Meanwhile, eco-friendly components and substances are used for improving the performance of the granular fertilizer, the components have the flexibility o
