Non-toxic residue-free efficient plant protective agent and preparation method thereof

The invention provides a non-toxic and residue-free efficient plant protective agent and a preparation method, and belongs to the technical field of plant protection.The preparation method of the non-toxic and residue-free efficient plant protective agent comprises the following steps that S1, solid raw materials in raw materials for preparing the plant protective agent are smashed through a solid raw material smashing mechanism; meanwhile, a liquid mixing mechanism is used for mixing and stirring liquid raw materials in the raw materials for preparing the plant protective agent; s2, the solid raw material smashing mechanism and the liquid mixing mechanism are driven by a transmission mechanism to rotate synchronously, and smashing and stirring of the raw materials are achieved; the whole preparation process of the plant protective agent is simple, material taking and processing are convenient and fast, solid raw materials can be subjected to double crushing, the crushing precision of the solid raw materials
