PROBLEM TO BE SOLVED: To provide a year-round production method for persimmon seedlings solving the following problem: in a conventional tree grafting where grafted trees are produced through sowing seeds on the open field and grafting buds in a summer or autumn season to generate new treetops next year, or cultivating the seedlings for one year and notching resting branches as scions in a spring season, it requires two years or more to finish the process from sowing to grafting, and the season for taking the scions is limited to a winter season and work for the notch grafting must be done outdoor because all to be used for the notch grafting are the resting branches even when using the scions.SOLUTION: The year-round production method for persimmon seedlings comprises the following process: managing grafted seedlings produced by a grafting method comprising using a main body of a rootstock sowed or cultured with culture soil and cultivated in a cell tray, a pot or the like, cutting the upper part or the lower part of a seminal leaf, making a cut in a vertical direction after cut, inserting a current-year branch, a resting branch or a refrigerated current branch into the cut so as to match their formative layers and taping them, by a water supply means provided with a water supply device and a drainage device and supplying water from the lower part than the grafted part or the bottom surfaces of the grafted seedlings just after grafting and growing the grafted seedling so as to become a successfully coherent one. The upper part of the water supply means is provided with light shielding equipment and rainproof heat-retaining equipment.COPYRIGHT: (C)2008,JPO&INPIT【課題】従来の接木では、露地に播種後、夏・秋期に芽接ぎし翌年に新梢発生させるか、1年間栽培し春期に休眠枝を穂木として切接ぎすることにより生産される。しかし、上記技術では播種から接木まで2年にまたがり、穂木を使用する場合も切接ぎは休眠枝しか使用できないため穂木の採取時期が冬季に限定され、屋外で作業する必要があった。【解決手段】セルトレー、ポット等で栽培された培土を有する播種ないし培養した台木の本体を使用し、子葉上部もしくは下部で切断し、切断後縦に切り込みを入れ当年枝、休眠枝もしくは冷蔵処理を行った当年枝を形成層が合うように差し込みテーピングを行う接木方法により生産した接木苗を接木直後から給水装置および排水装置等を備
