PROBLEM TO BE SOLVED: To provide a method for cultivating vegetable using cultivation trays enabling easy and rapid thinning-out work in a cultivating process after sowing and completely effective utilization of thinned out seedlings through cultivating them in the same cultivation condition as that for not-thinned ones, and excellent in cultivation efficiency and to provide a cultivation unit.SOLUTION: The method for cultivating vegetable using cultivation trays 1, 11 having implanting parts 2 and loopholes 3 formed alternately in any directions, at points where the direction of a plurality of equally-spaced rows (A), (B) and the direction of a plurality of equally-spaced rows (C), (D) intersecting with the direction of the spaced rows (A), (B) are joined, comprises the following process: superimposing the cultivation trays 1, 11 on each other passing the implanting parts 2 of the superimposed upper cultivation tray 1 through to the loopholes 3 of the lower cultivation tray 11 making the implanting parts 2 of the lower cultivation tray 11 expose out from the loopholes 3 of the cultivation tray 1 so as to form the cultivation unit 5 sowing the cultivation unit 5 with seeds and then separating the upper cultivation tray 1 from the lower cultivation tray 11 at the right time so as to continue to independently grow vegetables in each of the cultivation trays 1, 11.COPYRIGHT: (C)2008,JPO&INPIT【課題】 播種後の栽培過程における間引き作業が簡便迅速にでき、また間引き分についても同等の栽培条件下で栽培して完全な有効利用を図るとともに栽培効率のよい栽培トレーを用いた野菜栽培方法及び栽培ユニットを提供する。【解決手段】 栽培トレー1、11は、等間隔複数列A、B方向とそれと交差する等間隔複数列C、D方向との交わる点に植え込み部2と抜き孔3とを何れの方向にも交互に設けてある。栽培トレー1、11を2枚重ねにして、重ね合わせた上の栽培トレー1の植え込み部2を下の栽培トレー11の抜き孔3に挿通するとともに、下の栽培トレー11の植え込み部2を上の栽培トレー1の抜き孔3から露出させて栽培ユニット5を形成する。栽培ユニット5に播種した後、適時に上の栽培トレー1を下の栽培トレー11から離脱させてそれぞれの栽培トレー1、11に分離して野菜の生育を続ける。【選択図】図1
