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
