<P>PROBLEM TO BE SOLVED: To provide a greening method with a cuttage/seeding of pussy willows, so as to regenerate a leafy shade at a low cost, to have a revetment more stabled and to prevent the cuttage/seedling of the pussy willows from being washed away by a flood occurring even just after planting. ??<P>SOLUTION: Since the pussy willows are grown at the height of 20 cm above water surface on an existing revetment concrete wall 11 at a river, the root 29 is spread in a back-fill material 12, so that the revetment can be more stabilized. Moreover, a leafy shade can be regenerated at a low cost in a short period of time. Also, since a cuttage 25 is fixed in a drilled hole 13, the pussy willow is in a less danger of being pulled out and flown away from farmland 14 even in case of a flood right after the planting when the root 29 has not yet taken enough. ??<P>COPYRIGHT: (C)2010,JPO&INPIT ??
