<P>PROBLEM TO BE SOLVED: To provide spraying hydroponics of baby leaves enabling labor reduction in harvesting work, causing no continuous cropping damage, ensuring stable quality and yield without using pesticides, and taking no costs for transportation. <P>SOLUTION: The spraying hydroponics of baby leaves comprises the following: forming a cultivation chamber in a tunnel house over which a weed-proof sheet is laid to shield the cultivation chamber except for the time to put in/out a roller-attached cultivation container; putting a cultivation container having a bottom surface through which the roots of the plant are freely extendable downward on a rail-attached overhead counter having descending slant toward the transport opening side to a crop harvesting opening side; spreading sterilized culture medium containing culture soil over the bottom surface after subjecting the culture media to flow-preventing treatment; covering the open surface at the lower space of the overhead counter with shading raw material to form the cultivation chamber into a mist sprayed chamber; intermittently spraying water and culture solution mist having ≤50 μm of a liquid drop size to regulate the concentration of the ingredients of the organic nutrient solution in accordance with growth stage of the plant; and giving CO<SB>2</SB>to the plants. <P>COPYRIGHT: (C)2007,JPO&INPIT |
