CULTIVATION METHOD AND CULTIVATION DEVICE FOR HYGROPHYTE SEEDLING

PROBLEM TO BE SOLVED: To stably cultivate the large amount of the seedlings of reeds or the like by alternately repeating a flooding period for immersing a cell mold seedling bed composed of seeds and ridging in nutritious liquid for cultivation and a dry period for bringing it into contact with air. SOLUTION: In the seedling raising of hygrophytes, the cultivation is performed while alternately repeating the flooding period for immersing the cell mold seedling bed 13 composed of the seeds of the hygrophyte and the ridging 12 in the nutritious liquid 14 for the cultivation and the dry period for bringing it into contact with the air in the range of 2-12 hours preferably. Also, as this device for the cultivation, it is preferable that it is composed of a waterproof water culture bench for spreading the cell mold seedling bed 13 provided with the outer peripheral wall having a height capable of holding a water level capable of sufficiently flooding it and at least one each of a water supply pipe and a water level adjustment relay installed to the outer peripheral wall of the waterproof water culture bench, the water level adjustment relay is composed of at least one relay pipe and the water level of the nutritious liquid in the flooding period and the water level of the nutritious liquid in the dry period are automatically converted.
