Growth regulation microcapsule for angelica sinensis seed pellets and preparation method of growth regulation microcapsule

The invention discloses a growth regulation microcapsule for angelica sinensis seed pellets and a preparation method thereof, and the growth regulation microcapsule is prepared from the following raw materials in parts by weight: 30-40 parts of porous starch loaded chlormequat chloride, 15-20 parts of modified sodium carboxymethyl cellulose, 70-90 parts of deionized water and 0.8-2.5 parts of sodium dodecyl benzene sulfonate. Porous starch is wrapped by modified sodium carboxymethyl cellulose to load chlormequat chloride, so that chlormequat chloride loss and phytotoxicity to seeds are avoided, and early growth of angelica sinensis is guaranteed; the loaded medicine is slowly released by utilizing the charge neutralization and adsorption bridging effects of the positive charges of the modified sodium carboxymethyl cellulose and the negative charges of the starch, and the speed of the charge neutralization and adsorption bridging effects is controlled by adjusting the preparation process of the modified sodium
