PROBLEM TO BE SOLVED: To enable a sure automatic transplantation of canes into a main field using a transplanting machine for exclusive use and contriving a high harvest of >=95% rooting by sufficiently extending main roots and branched roots, executing acclimation and leaf pruning, concentrically growing many higher part-branched stems on a mother stem of cane and efficiently collecting the stems. SOLUTION: A higher part-branched stems lump in which many higher part-branched stems are centrically grown in crowds on a node of a mother stem (a) of cane is formed by repeatedly pruning an upper side stem containing a growing point of a terminal bud and the higher part-branched stem is separated to each piece having a bud base and a root base tissue part, then collected higher-part branched stems having same leaf number with each other are inserted into non-fertilized culture soil housed in collected seedlings growing tools, which are placed in a seedling growing house at an interval. Then the main root and the branched roots are sufficiently extended by fertilizing after the rooting, and the acclimation before transplanting to a main field is executed and seedling heights are adjusted by leaf prunning, and then automatic transplantations of cane with a desired inter-stock spacing by an exclusive transplanter is performed.
