The invention discloses an anticorrosive coating as well as a preparation method and application thereof, and relates to the technical field of high polymer materials and metal corrosion protection. The anticorrosive paint comprises the following components which are independently subpackaged: a component A: an epoxy resin prepolymer; component B: an epoxy resin curing agent, wherein the epoxy resin curing agent comprises an amino curing agent; component C: a functional molecule, wherein the functional molecule comprises alpha-lipoic acid. The coating has an innovative self-layering structure, so that the coating has a lotus leaf effect-like hydrophobic surface and super glue-like base layer adhesion at the same time, and the contradiction that the hydrophobicity and the adhesion force of a traditional coating are difficult to consider at the same time is solved. The existence of the dynamic disulfide bond not only endows intelligent release and potential self-repairing functions, but also provides possibility for degradation and chemical recovery of the coating material after the life cycle is ended, and conforms to the concepts of green chemistry and sustainable development.

The application provides an open-field cabbage water and fertilizer intelligent regulation method and device, and applies to the crop water and fertilizer precision regulation technical field.The method comprises the following steps: synchronously collecting short-impending meteorological data, cabbage body growth image data and hierarchical soil moisture data of an open-field cabbage planting area; taking a natural day as a time reference, integrating and processing the collected multi-source heterogeneous data, and generating daily characteristic data of a unified scale and representing growth correlation characteristics of the cabbage; inputting the daily characteristic data into a multi-source fusion intelligent decision model to obtain irrigation regulation parameters and fertilization regulation parameters of the open-field cabbage; and performing water and fertilizer supply operations on the open-field cabbage according to the irrigation regulation parameters and the fertilization regulation parameters.
