[PROBLEMS] To provide an epoch-making spray culture using by culture soil as a supporting material, solving the problems with a spray water culture method (spray culture) of prior inventions where conventional agricultural chemicals and chemical manure are not employed, and improving the solution. [MEANS FOR SOLVING PROBLEMS] (1) A spray water culture method supplying mist-like liquid manure directly to the roots of plant, characterized in that a culture bed where a culture nutrient medium container having a bottom face that enables the roots of plant to extend freely downward is set on a frame is used, the culture nutrient medium container is laid with culture nutrient medium containing culture soil and subjected to sterilization and saplings are grown, open surface of the space below the frame is covered with a material capable of shielding light to form a mist spray chamber, and liquid manure mist having liquid drop size of 50µm or less is sprayed downward from above the mist spray chamber. (2) The spray water culture method according to (1) characterized in that a non-woven fabric is laid on the bottom of the culture nutrient medium container having mesh-like bottom part and covered with culture nutrient medium. |
