This invention relates to the agricultural field, specifically to a method for preparing and applying a carbon dioxide fusion element trap. It addresses the problem that polymeric film-forming agents added to foliar fertilizers easily form a continuous, dense, and impermeable physical film on the leaf surface, making it difficult for carbon dioxide to enter, interfering with normal photosynthesis and transpiration, and thus causing abnormal leaf metabolism. The method involves immersing mesoporous silica microspheres in a PEI solution to obtain PEI-loaded microspheres, then adding a solution of gelatin, chitosan, glycerol, and glutaraldehyde to deionized water to form a composite gel base solution. Finally, selenomethionine, seaweed oligopeptides, and yeast extract are mixed with the composite gel base solution in warm water to obtain the carbon dioxide fusion element trap. This invention, through careful material selection and structural design, cleverly achieves a balance between strong adhesion and high permeability, allowing it to firmly adhere to the leaf surface and eliminating the defect of clogging leaf stomata.
