Rape moisture-proof seed coating material and application thereof

The invention discloses a rape moisture-proof seed coating material. The rape moisture-proof seed coating material is prepared from salicylic acid, N-(2-benzimidazole group)-methyl carbamate and boric acid, wherein the concentration of the salicylic acid is 0.1-0.5mmol/L, the weight percentage of the N-(2-benzimidazole group)-methyl carbamate is 0.01-0.05%, and the weight percentage of the boric acid is 0.1-0.2%. The rape moisture-proof seed coating material has a special formula, the germination rate of rape seeds and the waterlogging tolerance of rape seedlings under a moisture condition are improved, the seedlings are even, the diseases in a seedling stage are prevented, and the yield and oil content of rapes are improved. The seed coating material is convenient, simple and easy to operate, and can alleviate moisture damage of the rapes.
