Thus, six empty crop seedling holders 8 are supported on the support member 22 and lifted from the guide rail 23.
By repeating the above operation, the crop seedling A is placed on the shipping truck 10 from the crop seedling holder 8 in the work area 3, and the empty crop seedling holder 8 is stepped up and down on the holder support 15. Support in shape.

[7]
As described in the preceding item [6], in the state where the empty crop seedling support 8 is supported on the support support 15 in the vertical direction, a new crop seedling A is added to the empty crop seedling support 8. The case where the seedling is stored and the seedling is raised will be described.
In the state shown in FIG. 11 (b), the doors 13 and 14 are opened, the support base 9 is positioned at the position of the door 14, and the drive shaft 17 is rotationally driven in the reverse direction by a predetermined amount in the holding body support portion 15 and stopped. Then, the empty six crop seedling holders 8 supported by the lower end support member 22 are moved to the guide rail 23 by driving the support member 22 downward. Next, in the transport device 25, the drive sprocket 28 is rotationally driven in the reverse direction by a predetermined amount to stop it, and six empty crop seedling holders 8 are pushed out to the support base 9 by the pusher 32 (or the pusher 33), In the work area 3, new crop seedlings A are stored in six empty crop seedling holders 8.

When the operation of storing the new crop seedling A in the six empty crop seedling holders 8 in the work area 3 is completed, the six crop seedling holders 8 are moved from the support base 9 to the inside of the building 11, 6 The individual crop seedling holders 8 are supported by the guide rails 23, and the drive sprocket 28 is rotated and stopped in the forward direction by a predetermined amount in the transport device 25 to stop the six crop seedling holders 8 from the metal fittings 32 (or The lower part of the holding body supporting part 15 is passed by the pressing metal 33) and pushed out to the guide rail 5.
The crop seedling holder 8 is moved to the seedling area 1 by moving the crop seedling holder 8 pushed out to the guide rail 5 along the guide rail 5 to the inside of the greenhouse 4 while repeating the above operations. Put them in a state where they are housed side by side.
