High-affinity instant light-curing adhesive suitable for plants as well as preparation method and application of high-affinity instant light-curing adhesive

The invention discloses a high-affinity instant light-curing adhesive suitable for plants and a preparation method and application thereof.The adhesive is prepared from, by weight, 40-60 parts of 2-acrylic acid-2-hydroxy-3-phenoxy propyl ester and 0.6-1.4 parts of (2, 4, 6-trimethylbenzoyl) diphenyl phosphine oxide.The preparation method of the adhesive comprises the steps that all the components are weighed according to the weight part, and the adhesive is prepared through the steps that the adhesive is prepared; and mixing and fully stirring at normal temperature until a uniform glue mixture is obtained. The glue is applied to bonding of a sensor and a plant, and the using method comprises the steps that a small amount of glue is taken and dripped to the surface of a sensor or a plant leaf needing to be bonded, then a UV curing lamp is used for irradiating the dripping position of the glue for 2-10 s, and the glue is rapidly cured; or the glue is irradiated under natural light for more than 36 hours, so tha
