The present invention relates to a method for germinating ice plant seeds using highly concentrated oxygen water, and more specifically, to a method for germinating ice plant seeds using highly concentrated oxygen water to control germination rates and the length of roots by controlling dissolved oxygen amount in highly concentrated oxygen water and immersion time in highly concentrated oxygen water. The method for germinating ice plant seeds using highly concentrated oxygen water according to one embodiment of the present invention includes an immersion step, a drying step, a transplantation step, a covering step, and a spraying step. [Reference numerals] (S110) Step of immersing ice plant seeds in oxygen water; (S120) Step of drying the immersed ice plant seeds; (S130) Step of displanting the dried ice plant seed; (S140) Step of covering the ice plant seeds displanted in a tray with soil; (S150) Step of periodically spraying the oxygen water본 발명은 고농도 산소수를 이용한 아이스플랜트 발아법에 관한 것으로서, 구체적으로는 고농도 산소수에의 산소류 용존량 및 고농도 산소수에의 침지 시간을 조절하여 발아율 및 세근 길이를 조절하는 방법에 관한 것이다.
