本发明之课题在提供一种可藉简便且舒适之工作而实现花芽的开花控制之开花控制方法以及所使用之电刺激施加设备。 本发明之电刺激施加设备1具备电极101，以及保持有电极101，同时可把持自电极101分开的位置的握持具100，以及连接在电极101而能对电极101施加电位的电源200，以及将电源200之接地端子202连接到地面用之电极板311。操作者可于电极101上施加有电位之状态，将电极101沿着阔叶果树之枝条上移动，而于花芽施加电压。

An objective of this invention is to provide a blooming controlling method capable of realizing the blooming control by easy and comfortable working, and an electric stimulation providing device for the method. The electric stimulation device 1 contains electrode 101, and a holder 100 for reserving the electrode 101, and capable of holding the position separated from the electrode 101, and a power source 200 connected with the electrode 101 and capable of providing a potential to the electrode 101, and an electrode board 311 for connecting the ground terminal 202 of the power source 200 to a ground. An operator can move the electrode 101 along the branch of broad-leaved fruit tree while the potential is applied to electrode 101, so as to apply a voltage to a bud.
