The invention relates to a novel plant growth regulator bis-diethylaminoethanol phthalate citrate compound and a synthesis method and application thereof. The structure of the compound is shown in the specification. A preparation method comprises the following steps: in a reactor with a water distributor, controlling the molar ratio of phthalic acid or phthalic anhydride to N-N-diethylaminoethanol to (1:2)-(1:3) under the catalyst effect in an organic solvent; performing a backflow water distribution reaction for 3-9h at 110-150 DEG C until the distributed water quantity reaches a theoretical quantity; filtering; performing reduced pressure distillation of the filtrate to separate the organic solvent and excess diethylaminoethanol; decolorizing kettle bottom substances with activated clay; filtering, wherein the filtrate is bis-diethylaminoethanol phthalate; and salifying the bis-diethylaminoethanol phthalate with citric acid of twice molar quantity to obtain a white solid product. The compound provided by the invention has the functions of promoting seed germination, enhancing photosynthesis, promoting plant growth, increasing crop yield, improving fruit quality, enhancing plant stress resistance and the like, and is a broad-spectrum active regulator. Moreover, the production technology is simple, and industrial production is easy to realize.
