PROBLEM TO BE SOLVED: To provide a culture soil for growing seedlings, having light weight facilitating the transportation, and self-holding power to prevent the breaking down at transplantation, providing good transplantation operability, allowing the plant after the transplantation to be grown well, and not requiring frequent watering, and to provide a method for planting cuttings of vegetables by using the culture soil.SOLUTION: The culture soil for growing the seedlings is obtained by adding a water-soluble binder of 1-15 pts.wt. and a water-insoluble water-absorbing polymer of 0.5-10 pts.wt. to peat-moss and/or coco-peat of 100 pts.wt. as the total, further adding water in an amount of 400-1,200 pts.wt. as the total water content, and mixing the resultant product. The method for planting the cuttings of the vegetables includes adding the water in an amount required for forming 700-1,200 pts.wt. total water content to the culture soil and stirring and mixing the product again to afford slurry, flowing the resultant slurry into a container for growing the seedlings to fill the container, leaving the container for 3-5 hr to afford a solid culture soil containing the water by draining the excessive water, and planting the cuttings of flowering plants or vegetables in the resultant culture soil.COPYRIGHT: (C)2009,JPO&INPIT【課題】軽くて持ち運びが容易で、定植する際、自己支持力があって培土崩れがなく、定植作業性が良好で、定植後の植物の生育も良く、頻繁に灌水を行う必要がない育苗用培土及びこれを用いた野菜類の挿し木方法を提供する。【解決手段】ピートモス又は及びココピートの合計骨材量100重量部に、水溶性バインダー1~15重量部と、非水溶性の吸水ポリマー0.5~10重量部を加え、これに総水分量が400~1200重量部となる水を加えて混合して成ることを特徴とする育苗用培土。総水分量が700~1200重量部になる量の水を加えて再び撹拌混合してスラリーとなし、次いでこのスラリーを育苗用容器に流し込み充填した後3~5時間以上放置して、余分な水分が排水されて水を含んだ固体の培土になってから草花や野菜類の苗を挿し木することを特徴とする野菜類の挿し木方法。【選択図】図1
