ている。《Prior art》 In the fixed medium method and hydroponic cultivation, a nutrient solution is supplied to the roots of the cultivated crops and the nutrient solution is absorbed from the roots, but the nutrient solution supplied to the cultivated crops is Additive gas such as oxygen is dissolved together with liquid fertilizer.
従来、養液に酸素を溶解させる手段として、液
肥を混入した養液を開放容器で構成した混合槽に
貯溜し、この混合槽内の養液内に空気を供給して
バブリングさせることにより、養液に酸素を吸収

題があつた。《Problem to be solved》 However, with the conventional method that dissolves oxygen in the nutrient solution by bubbling air, gas components are absorbed through contact with the rising air bubbles, but the Since the partial pressure of oxygen is 1/5 of that of the supplied air, there was a problem that the amount of absorbed oxygen was small and it was not possible to dissolve enough oxygen into the nutrient solution.
そこで、酸素ガスを使用してバブリングするこ
とも考えられるが、この場合、養液中を上昇する
間に溶解しなかつた酸素は系外に放出されること
になり、酸素の有効消費量が少なく無駄な消費が
多くなつて経済的でないという問題があつた。 Therefore, bubbling using oxygen gas may be considered, but in this case, the oxygen that is not dissolved while rising in the nutrient solution will be released outside the system, reducing the effective consumption of oxygen. There was a problem that there was a lot of wasteful consumption and it was not economical.
