Problem to be solved: to provide a method for cultivating the soft stems of the leaves and beaches, which are rich in nourishment, less bitterness and fragrance, and are more susceptible to many people.Solution: the plant of the foliage or the foolproof wax is collected or cultivated, and then the stem 1 is expanded as a soft stalk and harvested in the state where the stock 1 is placed in an environment in which sunlight is shielded. The method of growing the covering material 11 in accordance with the elongation of the stalk 1F by covering the seedling 1 with the sealant 5 containing the seaweed 5 in the seedling of the seedling 1 and the covering material 11 including the bamboo chip.Diagram【課題】滋養に富んでおり、苦味や香りが少なく、多くの人に好まれ易い、明日葉や浜ぼうふうの軟質茎を栽培する方法を提供する。【解決手段】明日葉又は浜ぼうふうの成株1を採取するか栽培し、その後、成株1を太陽光を遮蔽した環境に置いた状態で、茎を軟質茎として伸長させて収穫する。成株1の苗床に海藻5を敷き、また、竹チップなどを含む被覆材11で、成株1を覆い、茎1fの伸長にあわせて、被覆材11を厚くする栽培方法。【選択図】図1
