Abstract

The invention discloses a temperature-sensitive wall material. The temperature-sensitive wall material comprises a temperature-sensitive material modified polymer wall material, wherein the temperature-sensitive material is polyvinylpyrrolidone, glycerophosphate, stearic acid, galactose-removed xyloglucan or gelatin-chitosan, poly(N-isopropylacrylamide) and hydroxybutyl chitosan. The temperature-sensitive wall material releases drugs at different temperatures, the drug release time is flexibly controlled, the phytotoxicity is reduced, and the drug action time is prolonged. The temperature-sensitive wall material can be applied to whole-course pesticide application protection of the growth cycle of crops, the chemical application frequency is reduced, and the crop management efficiency is improved. The invention also provides a corresponding microcapsule and a preparation method.
