PROBLEM TO BE SOLVED: To provide cultivation methods in which watering is not required to save labor and in which cultivation soil mixed into a liquid phase appropriate for various species is selected.SOLUTION: A cultivation method in which a liquid phase of a cultivation soil mixed with Akadama, leaf mold, zeolite, or pumice is prepared for bottom irrigation comprises storing water in a fitting tank 3 which is used as a placing table under a cultivation container 1, has a structure in which rain is dropped from the cultivation soil to be stored in the tank in the outdoors, the method supplying water by capillarity by fixing a water absorbing string C, which is a cylindrically rolled micro cloth A with good water absorbency on which a head portion B is attached, on the bottom of the cultivation container 1.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】水遣りの要らない省力的栽培と同時に多品種に適するような液相に混合した培養土を選択し栽培する方法を提供する。【解決手段】赤玉土と腐葉土ゼオライト又は軽石を混合した培養土の液相を調整して栽培する底潅水の構成として、栽培容器1の下に置台とするはめ込みタンク3に水を貯水し、屋外では雨を培養土から下に落としてタンクに貯水する構造とし、吸水性の良いマイクロクロスAの布を円柱状に巻いて頭部Bを付けた吸水紐Cを栽培容器1の底に固定して毛細管現象によって水を供給する栽培方法。【選択図】図1
