Abstract

The invention discloses a micro-encapsulated broad spectrum pollution-free fertilizer with pesticide, a preparation method and application thereof. The fertilizer with pesticide consists of 1 to 10 portions of pesticide microcapsule and 90 to 99 portions of nutrient substances in portion by weight. The preparation method thereof mainly comprises the following steps: filling the pesticide into a reaction kettle and thoroughly dissolving the pesticide by a solvent, adding wall material monomer and Tween into the kettle respectively, evenly mixing the solution, conveying the mixed solution to a shear emulsion reaction kettle by a pump to carry out shear emulsion reaction, and forming capsules to obtain the pesticide microcapsule; and adding the nutrient substances into the pesticide microcapsule, fully stirring and evenly mixing the mixture to obtain the natural product micro-encapsulated broad spectrum pollution-free fertilizer with pesticide. The chemical compatibility and physical stability problem of the prior pesticide fertilizer preparation in a same system can be effectively solved by using the method. The product has the advantages that the fertilizer with pesticide has shielding and slow-release functions, the chemical compatibility and physical stability are good, the drug effect is durable, the using cost is low, and the production process is simple.

Description

technical field [0001] The invention relates to a non-public drug fertilizer, in particular to a high-efficiency, low-cost microencapsulated broad-spectrum pollution-free drug fertilizer and its preparation method and application. Background technique [0002] Japan began to mix the herbicide pentachlorophenol (pcp) into fertilizers as a base fertilizer in the 1960s, in order to achieve the purpose of saving manpower and continuing the weeding effect. In the mid-1960s, the United States found that procyon can strongly inhibit nitrification and denitrification, reduce nitrogen loss, and can also enhance biological nitrogen fixation, increase nitrogen content in soil, and effectively enhance fertilizer efficiency. The mixed application of nitrogen, phosphorus, potassium fertilizer and 2,4-d in corn production also showed obvious synergistic effect on weeding and yield. In the early 1980s, the United States proposed more than 300 kinds of herbicides and 5 kinds of compound fer...
