Abstract

The invention discloses an adhesive blue fluorescent coating and a preparation method and application thereof. The preparation method comprises the following steps: S1, preparing blue fluorescent carbon quantum dots from citric acid and polyethyleneimine; s2, dissolving the blue fluorescent carbon quantum dots prepared in the step S1 in water to obtain a blue fluorescent carbon quantum dot solution; s3, co-depositing the blue fluorescent carbon quantum dot solution and a polyphenol solution on the surface of a substrate, obtaining an adhesive blue fluorescent coating, wherein the polyphenol solution is an amine-induced polymerization polyphenol compound solution. The surface of the coating is provided with fine ripples, the fluorescent property is strong, the thermal stability is good, theadhesion is better, the anti-scouring property is stronger, and the fluorescent property can be continuously maintained; the plant growth regulator is sprayed on the surface of a plant to effectivelyimprove the photosynthetic activity of the plant, effectively promote the growth of the plant, is convenient to use, green, pollution-free, low in cost and high in universality, effectively absorbs ultraviolet rays, and prevents the plant from being stressed by the ultraviolet rays, thereby improving the stress resistance of the plant.

Description

technical field

[0001] The invention relates to the technical field of fluorescent materials and plant applications, in particular to an adhesive blue fluorescent coating and a preparation method and application thereof. Background technique

[0002] Plant yield is closely related to light use efficiency. At present, the utilization efficiency of sunlight by plants is less than 1%. This is mainly because only blue light and red light can be efficiently utilized by plant photosynthesis in sunlight, while plants are sensitive to ultraviolet light and green light. Light utilization efficiency is very low. In addition, ultraviolet light not only cannot be directly used by plants, but also easily causes light stress and damages plants. Therefore, converting these ineffective or low-efficiency light into blue light and red light required for plant photosynthesis not only helps to improve light utilization efficiency, but also protects plants from UV stress.
