The utility model discloses a special hydroponic floating plate for
seedling raising, which relates to the technical field of vegetable planting and comprises a planting plate and a
seedling raising frame, the planting plate is square, and the upper and lower parts of the planting plate are planes. A plurality of planting holes are evenly formed in the planting plate,
seedling raising frames are inserted into the planting holes, the upper portions of the seedling raising frames are provided with upper frame edges extending outwards, and the seedling raising frames are fixed to the planting holes. Threaded sectors are arranged in the seedling raising frame, buckles of the threaded sectors are clamped in the frame body of the lower frame edge, and fan blades extend out of clamping groove seams in the inner side face of the lower frame edge. The threaded sector can move around along with the growth of the
root system, and an
air cavity can be formed between the seedling raising frame and the
nutrient solution below the planting plate. The
air cavity enables lower root systems of seedlings to be in contact with
nutrient solution and upper root systems to be in contact with air, so that
root rot is prevented. The threaded sector moves towards the periphery along with
root growth, and the survival space of seedlings is increased. The seedling raising frame can be repeatedly used,
sponge is reduced, green
moss generated when the
nutrient solution is directly irradiated by
sunlight is reduced, the cost is reduced, and meanwhile environmental
pollution is reduced.
