Abstract: The invention relates to a double-microenvironment three-layer bionic hydrogel scaffold and a preparation method and application thereof, which are characterized in that includes a cartilage layer GL-HPKGN, an intermediate layer GL-GMA, and a bone layer GL-HP/GMAAT; by an enzymatic crosslinking reaction based on hydroxyphenylpropionic acid (HPA), kartogenin (KGN) is grafted onto gelatin to form a cartilage-specific microenvironment in GL-HPKGN; Based on hydroxyphenylpropionic acid (HPA), a dual crosslinking network was formed by enzyme crosslinking reaction and methacryloyl-glycidyl dimethicone (GMA) photo-crosslinking reaction, which was used to graft atorvastatin (AT) onto gelatin, forming GL-HP/GMAAT with bone-specific microenvironment; the intermediate layer GL-GMA was beneficial for forming a clear and defined cartilage-bone integrated structure. The introduction of the tide-line intermediate layer GL-GMA facilitated the formation of well-defined chondro-bone integrated structures.

Abstract: The present disclosure relates to the technical field of pest capturing in protection of tea trees, in particular to a pest trap for tea planting. The pest trap includes a trap framework and a light-emitting diode (LED) lamp; an upper end of the trap framework is provided with a support which is used for clamping the LED lamp; a board for trapping pests coated with sex pheromone on a surface is arranged inside the trap framework; a heating source is arranged on one side of the board for trapping pests and is used for making the sex pheromone to be volatilized faster and farther; a mesh enclosure used for trapping pests is arranged on an outer side of the trap framework; and a small circular hole is formed in a bottom of the mesh enclosure.
