[0013] As a further description of the above technical solution:

[0014] In the step 1), the aluminum hydroxide composite sodium silicate is screened through 3000 mesh.

[0015] As a further description of the above technical solution:

[0016] In the step 3), the pulverization is performed using a jet mill.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] 1. In the present invention, by taking fumed silica and aluminum hydroxide composite sodium silicate as raw materials, mixing the raw materials, and crushing the mixture, the ultrafine powder obtained has the characteristics of good adsorption, strong suspension, large bearing capacity, wide diffusion and uniform dispersion.

[0019] 2. In the present invention, the ultrafine powder can effectively reduce the air humidity in the greenhouse, improve the diffusion, permeability and uniformity of the mixed agent, easily reach the surface of the crop, adsorb on the back of the crop, do not pollute the fruit surface, can improve the efficacy of the drug, reduce the amount of medicine used, save time and other advantages.
