The invention provides an application of licorice carbon quantum dots as a drip irrigation fertilizer in improvement of salt tolerance of crops, and relates to the technical field of agricultural production. The preparation method of the licorice carbon quantum dots comprises the following steps: adding water into crushed licorice, carrying out a hydrothermal reaction, and centrifuging after the reaction is completed to obtain brown liquid with sweet fragrance, namely the licorice carbon quantum dots. The application method comprises the following steps: dispersing the licorice carbon quantum dots in water to prepare the drip irrigation fertilizer, and then soaking crop roots with the drip irrigation fertilizer. The used material is common liquorice which is cheap and easy to obtain; the synthesis method is simple, and used equipment is common; the synthesized LiCBs can be prepared and used after being centrifuged. The LiCBs drip irrigation fertilizer can change the plant type of crops under salt stress, and
