A kind of plant setting case is suitable for cultivating seeds into plant, which cultivates box, one first every disk, one second every disk and a Flexible element comprising one. First every in the detachable liftoff accommodating what cultivation box of disk, this first is used to place the seed every disk and has several spaced first grids for this. This second every in the detachable liftoff accommodating what cultivation box of disk, this second every disk in a top and bottom direction high what this first every disk. The detachable liftoff setting what cultivation box of the Flexible element and this first every the one of them of disk and this second every disk, when the plant growth this can first second gradually increased every disk with this every the spacing that disk is separated by, and make the bathmic active force of the Flexible element one reversed what plant of generation, thereby, make the plant simultaneously can cross growth.一種植物栽植箱,適用於將種子培育成植物,該植物栽植箱包含一培育盒、一第一隔盤、一第二隔盤,及一彈性單元。 該第一隔盤可卸離地容置於該培育盒內,該第一隔盤用來放置該種子且具有數個間隔排列的第一網格。該第二隔盤可卸離地容置於該培育盒內,該第二隔盤在一頂底方向上高於該第一隔盤。該彈性單元可卸離地設置於該培育盒及該第一隔盤的其中一者與該第二隔盤,當該植物生長時會使該第一隔盤與該第二隔盤相隔的一間距逐漸增加,並使該彈性單元產生一反向於該植物的生長力的作用力,藉此,使該植物同時能橫向生長。
