By allowing 18 to be held at a plurality of turning angles with respect to the support frame 17, when the auxiliary seedlings are loaded on the auxiliary seedling table, the auxiliary seedlings in the auxiliary seedling table are supplied to the seedling table of the planting device. In order to solve the above-mentioned problems, the auxiliary seedling stand is swiveled so as to be suitable for various kinds of work such as when supplying contents to a container, and each swivel position can be held to perform various works. It was made possible.

(E) Action When loading auxiliary seedlings on an auxiliary seedling stand, put the auxiliary seedling stand on an inverted U-shaped support frame and place a container such as a fertilizer tank or a pump or other equipment under the support frame. When installing, if they are installed in the space surrounded by the inverted U-shaped support frame, the space can be effectively used and they can be protected, and the spare seedlings can be used as an auxiliary seedling stand. When supplying the auxiliary seedling stand to the front-back direction, one stopper holds that position, and when supplying the auxiliary seedling of the auxiliary seedling stand to the seedling table of the planting device, the auxiliary seedling is pulled out from the auxiliary seedling stand. If the auxiliary seedling table is horizontally swung to an angle that facilitates supply to the seedling table, the other stoppers will hold this swivel angle, and the auxiliary seedlings should not be swung while the spare seedlings are inserted and removed. The fertilizer is added to the container installed at the bottom of the support frame. When supplying other necessary items, or when inspecting equipment such as pumps installed in the part, another stopper holds the auxiliary seedling stand in a position retracted from the support frame.
