IPC: A01G9/02
Filed: 2002-02-18
Abstract: <P>PROBLEM TO BE SOLVED: To solve problems that a solution can be reached because too much water results in a root rot state though there is a method for sucking water from the lower part of a flower pot as a method for supplying the water to a plant therein.  <P>SOLUTION: The pot is a combination of a pot body 1 for providing water-soaked cultivation with a water storage tank 6 in appearance. When the amount of water is large, root rot is caused. The oxygen supply is found to cause no problem. In the pot body 1 for supplying water from the base, the main base of culture soil 4 is not brought into close contact or brought near to the water surface when filled with the water. The pot body 1 has air- permeable holes 8 and 2 for supplying the oxygen to roots just under the base of the culture soil 4 and a sidewall, water-flow holes 3 for supplying the water in the lowermost part and water absorbing cylinders 5 for transferring the water to the upper part. Since the root rot is easily caused in the part of the water absorbing cylinders 5, an inorganic material such as rough sand or pumice is placed therein and utilized to supply the oxygen. A space between the main base of the culture soil 4 and the water surface when filled with the water is preferably in a state of 2-3 cm. When the culture soil 4 and the water absorbing parts are dried, water absorption is deteriorated. Thereby, the culture soil 4 and the water absorbing parts are preferably manually watered and sufficiently wetted.  <P>COPYRIGHT: (C)2003,JPO
