The invention belongs to the technical field of plant grafting, and particularly relates to an early identification method for healing degree and affinity of fruit tree grafted rootstocks and scions. The early identification method comprises the following steps: grafting a scion to a stock, culturing for 10-20 days, inserting the base part of the stock into a fast green staining solution for staining, and judging the healing degree and affinity according to the staining condition. Different rootstock and scion combinations after grafting are dyed by using the dyeing agent fast green, the transportation difference of the fast green in the grafted rootstock and scion combinations is analyzed, the rootstock and scion healing degree and affinity can be rapidly judged, and technical and theoretical supports are provided for rapid rootstock breeding, rootstock and scion combination screening and rootstock application.

The application discloses an epoxidation catalyst and a liquid-phase preparation method. Titanium is grafted into the skeleton of a carrier SiO2 by adopting a liquid-phase static grafting method. The introduction of rare earth elements improves the stability of the carrier structure and active components, strengthens the directional grafting of titanium and the distribution of active sites, improves the activity and stability of the catalyst in olefin epoxidation, and avoids the corrosion of equipment and the poisoning of copper-based catalysts in the POSM process in the whole process without introducing chlorine elements.
