PROBLEM TO BE SOLVED: To provide a vertical-type cultivation apparatus with ultrasonic atomization, the apparatus comprising a vertically supported cultivating pipe by which more mist stays in balance around the root hair, and, after the mist is absorbed from the root hair, it naturally withdraws from the surroundings of the root hair.SOLUTION: According to the present invention, a cultivation apparatus 100 with ultrasonic atomization, the apparatus comprises: an ultrasonic atomizer 103 having an atomizing liquid tank for storing a liquid fertilizer, an ultrasonic vibrator for atomizing the liquid fertilizer by ultrasonic vibration, and an oscillator for vibrating the ultrasonic vibrator, and supplying the generated mist to the interior of a cultivation pipe 101 from a mist introduction port 120 disposed in the cultivation pipe 101. Here, the lower end of a seedling-holding portion is positioned higher than the lower end of an opening portion, The cross-sectional area of the retention portion 142, which is the inner space of a main body portion, is larger the closer it is located to the side communicating with the inside of the cultivation tube 101, and is smaller the closer it is located to side communicating with the seedling holding portion.SELECTED DRAWING: Figure 14【課題】霧が根毛の周囲により多く且つバランス良く滞留し、根毛から吸収された後、根毛の周囲から自然に離脱してゆく、栽培管を垂直に保持した垂直型の超音波霧化栽培装置を提供する。【解決手段】液肥を貯留する霧化液槽と、液肥を超音波振動で霧化する超音波振動子と、超音波振動子を振動させる発振器とを有し、発生させた霧を栽培管１０１に設けられた霧導入口１２０から栽培管１０１の内部に供給する超音波霧化器１０３とを備え、苗保持部の下端が、開口部の下端より高く位置し、本体部の内部空間である滞留部１４２の断面積が、栽培管１０１の内部と連通する側ほど大きく、且つ、苗保持部と連通する側ほど小さい超音波霧化栽培装置１００。【選択図】図１４
