▎ 摘　　要

NOVELTY - Preparing hydrolyzed collagen polypeptide multi-effect foliar fertilizer based on graphene oxide activation involves adding the hydrolyzed collagen polypeptide into graphene oxide dispersion liquid, stirring and mixing for 30-45 minutes to obtain the pre-mixed material liquid, the pre-mixing material liquid is added into the microwave ultrasonic mixing reactor, at the same time metal salt solution is added then reacting for 30-45 minutes at the temperature of 40-45 degrees Celsius to obtain the mixed solution, mixing the mixed solution anti-reverse agent and plant growth regulator, stirring, then spray drying or freeze drying to obtain the hydrolyzed collagen polypeptide multi-effect foliar fertilizer based on graphene oxide activation. USE - Method for preparing hydrolyzed collagen polypeptide multi-effect foliar fertilizer based on graphene. ADVANTAGE - The method provides multi-effect foliar fertilizer based on hydrolyzed collagen polypeptide chelate the multi- effect foliar fertilizer with obvious yield increasing effect. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the present invention based on graphene oxide activated hydrolyzed collagen polypeptide multi-effect foliar fertilizer preparation method.
