PROBLEM TO BE SOLVED: To provide disinfection and storage of a seedling-raising material after use, and more specifically, methods of disinfecting and storing an expandable seedling-raising material which is handleable and economical and significantly reduces its volume compared to that during growth.SOLUTION: The present invention provides methods of disinfecting a seedling-raising container which comprises: expandable seedling-raising pots 1 each formed by bending a rectangular sheet cylindrically into a container shape and grating trays 2 each having a plurality of recesses 2a which can vertically arrange and support the expandable seedling-raising pots. After seedlings are raised, the seedling-raising pots 1 are separated from the grating trays 2, and sheets obtained by expanding the seedling-raising pots 1 and the grating trays 2 are stacked respectively into rectangular solid-shaped masses, immersed in a disinfectant solution in the state of these stacked masses, and then left in the state of the stacked masses for storage after the disinfection.COPYRIGHT: (C)2015,JPO&INPIT【課題】使用後の育苗資材の消毒及び保管に際し、その容積を栽培時より大幅に減容させ、取扱い作業性、経済性に優れた展開式育苗資材の消毒及び保管の方法を提供する。【解決手段】矩形シートを筒状に曲折して容器状を成す展開式育苗ポット1と、この展開式育苗ポットを立設支承可能な複数の凹部2aを有する格子状トレー2とから構成される育苗コンテナの消毒方法であって、種苗育成後の育苗ポット1と格子状トレー2を分離し、育苗ポット1を展開したシート及び格子状トレー2を各々立体方形状の塊に積層し、この積層塊の状態で消毒液に浸漬する。そして、消毒後の積層塊のそのままの状態で保管する。【選択図】図6
