Abstract

The invention discloses a microcapsule insecticide-fertilizer preparation, a preparation method and application thereof. The preparation consists of the following components in part by weight: 1 to 30 parts of pesticide microcapsules and 70 to 99 parts of nutrient substance. The preparation method mainly comprises the following steps of: after fully dissolving a pesticide with a solvent, adding a wall material monomer into solution and mixing uniformly; transporting a mixture into a shear dispersion reaction kettle which is filled with smashed capsule bodies; stirring the mixture and the capsule bodies so that the capsules fully absorb the solution; performing a shear dispersion reaction to form capsules; performing solid-liquid separation and drying to prepare the pesticide microcapsules; adding the nutrient substances into the pesticide microcapsules; and fully stirring and uniformly mixing to prepare the microcapsule insecticide-fertilizer preparation. By using the microcapsule insecticide-fertilizer preparation and the preparation method, the problems of the chemical compatibility and the physical stability of the conventional insecticide-fertilizer preparation in the same system are solved effectively. A product of the invention has the advantages of: shielding and slow-releasing functions, high chemical compatibility and physical stability, lasting pesticide effect, natural degradability, no environment pollution, low use cost and simple production process.

Description

technical field [0001] The invention relates to a microcapsule preparation, in particular to a high-efficiency and low-cost microcapsule fertilizer preparation 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 fertilizers for mixed use, mos...
