Abstract

The invention discloses a composite medicinal fertilizer and a preparation method thereof. The composite medicinal fertilizer consists of the following components in percentage by weight: 30-40 percent of a nitrogen-phosphorus-potassium mixed fertilizer, 22-30 percent of imidacloprid, 0.1-1 percent of difenoconazole, 0.1-0.5 percent of agritol, 5-8 percent of a wrapping agent and 24-36 percent of boric magnesium slag. The preparation method comprises the steps of crushing the boric magnesium slag to 80-100 meshes to obtain boric magnesium slag particles, adding the agritol into the boric magnesium slag particles, uniformly mixing the agritol and the boric magnesium slag particles, then mixing the mixture with nitrogen-phosphorus-potassium mixed fertilizer particles to obtain boric magnesium slag and nitrogen-phosphorus-potassium mixed fertilizer mixed particles, adding the imidacloprid and the difenoconazole into water for uniform stirring, uniformly spraying the imidacloprid and difenoconazole mixed aqueous solution on the surfaces of the boric magnesium slag and nitrogen-phosphorus-potassium mixed fertilizer mixed particles, wrapping the particles through the wrapping agent, and performing screening to obtain the composite medicinal fertilizer. The composite medicinal fertilizer has the advantages that the fertilizer has rich nutritional components; in a production process, high-temperature drying is not needed, so that pesticide components can be effectively guaranteed; the composite medicinal fertilizer is safe, environment-friendly and suitable for industrial production.

Description

technical field [0001] The invention relates to a compound medicinal fertilizer and a preparation method thereof. Background technique [0002] In agricultural production, pesticides and fertilizers play an essential role in ensuring crop yields. Pesticides kill pests, fungi, and other organisms that harm crops; fertilizers provide essential nutrients to plants and improve soil quality. With the development of science and technology, functional compound fertilizers that not only kill and suppress crop diseases and insect pests but also provide nutrition for crops have become the main research direction. [0003] At present, the compound medicinal fertilizer is mainly made of fertilizer, and the coating method is used to wrap the pesticide on the surface of the fertilizer particles. The main ingredients used are generally nitrogen, phosphorus, and potassium macronutrient fertilizers, ignoring the use of micronutrient fertilizers. For crops, both macronutrients and micronutr...
