The above-mentioned inorganic porous material was applied to rice hydroponic fields every 30 days.
The case where the amount of 10 g / m 2 was removed three times and the case where the amount was not removed at all were compared. * Results. (1) When inorganic porous material is sprayed After 30 days have passed, the roots have a lot of root hair and growth is good. Good heading rate at heading. (2) In the case where the inorganic porous material was not sprayed After 30 days, root hair was small and mold was generated. Low heading rate at heading.
