PURPOSE: To raise plant seeds with improved quality by treating plant seeds with ozonous water followed by seeding to enhance the water absorbability for the seeds and shorten the water-absorbing time to expedite the germination of said seeds.
CONSTITUTION: In a water-absorbing system for plant seeds made up of (A) a thermostatic water tank 1 designed to bring the ozonous water from an ozonous water production unit 7 to a set temperature and feed to the plant seeds the resulting ozonous water at the constant temperature set and (B) a seed dipping tank 2 designed to bring said ozonous water at the constant temperature into contact with the plant seeds, a pipe part 3 is set up in the thermostatic water tank 1 to bring the ozonous water from the ozonous water production unit 7 to the set temperature, and the resulting ozonous water at the constant temperature is fed to the plant seeds in the dipping tank 2 and an agitator 4 is actuated in the dipping tank 2 to treat the plant seeds with the ozonous water. Thence, the plant seeds thus treated are seeded, thereby enhancing the water absorbability of the plant seeds and expediting the germination, thus raising the plant seeds.
