Tissue culture device for botanical experiments

The invention provides a tissue culture device for botanical experiments. The tissue culture device comprises a nutrient solution replenishing bottle, a balance, a filter ring, an alcohol lamp, a first wafer group and a second wafer group, wherein the nutrient solution replenishing bottle is hung at the bottom of a slide sleeve through a hook, a culture cup is arranged in the middle of the inner side of a glass container, and an overflow mouth of an annular structure is formed in the upper end of the culture cup; the filter ring is closely embedded between the glass container and the culture cup, a micropump is further disposed in the part, at the lower side of the filter ring, of the glass container, and an electronic igniter is mounted on the part, on the side of the alcohol lamp, of a bracket; a fluorescent lamp is installed in the middle of the bottom of a fixing plate. After the second wafer group is at a closed state, sunlight for growth of plant tissue is generated by the fluorescent lamp, and a nutrie
