Embodiment 1
[0027] Put the cyclodextrin into the shear dispersion reaction kettle; put the abamectin into the reaction kettle and fully dissolve it with turpentine, add toluene diisocyanate and mix evenly, and pump the mixed solution to the In the fine shear dispersion reaction kettle, stir to let the cyclodextrin fully absorb the solution, add water with ethanolamine to adjust the pH value to 8, and shear and disperse to disperse the cyclodextrin of the adsorbed solution in the water, at a temperature of 30 ° C Under the conditions, the shear dispersion reaction was carried out for 30 minutes, and after forming capsules, the pesticide microcapsules were prepared by solid-liquid separation and drying; the prepared pesticide microcapsules were put into a mixer, and the amino acid aqueous solution was added, fully stirred and mixed evenly, and the prepared pesticide microcapsules were prepared. Obtain microcapsule medicinal fertilizer preparation.

Embodiment 2
[0053] Put the pulverized fly ash with a particle size of 500 mesh into the shear dispersion reaction kettle; put bensulfuron-methyl into the reaction kettle and fully dissolve it with eucalyptus oil, then add hexamethylene diisocyanate and mix evenly, mix the mixture The good solution is pumped to the shear dispersion reactor with fly ash, stirred to allow the fly ash to fully absorb the solution, adding water with ethanolamine to adjust the pH value to 10, and sheared to disperse the fly ash to absorb the solution. In dispersion water, under the condition of temperature of 60°C, shear and disperse for 120 minutes. After forming capsules, separate and dry the pesticide microcapsules to obtain pesticide microcapsules; put the prepared pesticide microcapsules into a mixer, add The organic fertilizer is fully stirred and mixed uniformly to prepare a microcapsule medicinal fertilizer preparation.

Embodiment 3
[0079] Put the crushed kiln dust with a particle size of 400 mesh into the shear dispersion reaction kettle; put the brassinolide into the reaction kettle and fully dissolve it with cyclohexanone, add xylene isocyanate and mix evenly, and mix the mixed solution Use a pump to transport the kiln dust into the shear dispersion reactor, stir to allow the kiln dust to fully absorb the solution, add water to adjust the pH value to 9 with ethanolamine, shear and disperse the kiln dust that absorbs the solution, and disperse it in the water. Under the condition of 50°C, the shear dispersion reaction was carried out for 60 minutes. After the capsules were formed, the pesticide microcapsules were obtained through solid-liquid separation and drying; Fully stir and mix uniformly to prepare microcapsule medicinal fertilizer preparation.
[0080] The raw materials used and the weight ratio of the prepared pesticide microcapsules are:
[0081] Brassinolide 15 parts
[0082] Cyclohexanone 4...
