抄録

Growing agricultural plants with liquid fertilizer is called hydroponic culture. The hydroponic system is widely used because cultivation conditions can be controlled much easier than soil cultivation. For example, oxygen concentration control is difficult with soil cultivation, but it can be easily controlled with the hydroponic system. Here we generated microbubble in the liquid fertilizer and maintained saturated oxygen concentration over few months and we then evaluated its effect on the plant growth measured as biomass amount. The microbubble was provided by commercially available home use microbubble generator. We focused on 4 crops (tomato, broccoli, cress, rush) that are cultivating around Kumamoto-prefecture, especially Kumamoto is known as the top share producer of rush, producing over 90% of the national production volume. There was no noticeable difference in the biomass amount between those plants cultured hydroponically with microbubble-aided and non-microbubble-aided water. However, it has turned out that there is a tendency to prompt growth in plants grown by soil cultivation with irrigation of microbubble-aided water. In addition，in the case of rush there was a significant difference in the stalk and root growth between the cultivation with microbubble-aided and non-microbubble-aided water.
