The invention provides a disc
seedling cultivation device. The device comprises a top plate, a bottom plate and a
water supply cavity, wherein the
water supply cavity is arranged between the top plate and the bottom plate, and the
water supply cavity is connected with a water supply inlet
pipe; a plurality of planting holes are formed in the top plate, a planting groove is formed in each planting hole, the upper ends of the planting grooves are connected with the top plate, the lower ends of the planting grooves are located in the water supply cavity, and there is a gap between the lower ends of the planting grooves and the bottom plate; a water supply hole is formed in the bottom of each planting groove, filter cover bodies are arranged in the water supply holes,
siphon diversion columns are arranged in the filter cover bodies, and the lower ends of the
siphon diversion columns penetrate the water supply holes and extend to the water supply cavity; clamping connection parts are arranged in the middle of the planting grooves, filtering plate bodies are connected with the clamping connection parts in a clamped mode, and the planting grooves are divided into
seedling cultivation areas and conduction areas by the filtering plate bodies; conduction substrate is contained in the conduction areas;
seedling cultivation sleeves are arranged in the seedling cultivation areas, and seedling cultivation substrate is contained in the seedling cultivation sleeves; a plurality of gas guiding holes are formed in the side wall of each seedling cultivation area, and the gas guiding holes are communicated with the seedling cultivation areas and the water supply cavity; a drain
pipe is connected to the lower end of the water supply cavity. By means of the disc seedling cultivation device, the
water content in the process of seedling cultivation can be guaranteed,
transplantation is convenient, and damage to seedlings is reduced.
