(Operation of Example)

Further, the operation of one embodiment of the plant cultivation apparatus according to the present invention will be described in detail with reference to FIGS.

Seeding step: Operation of seeding device 200 (FIGS. 1 to 1)
13, see FIGS. 19 to 21)

In the seeding device 200 , the nursery box transporting device 210
However, the nursery box mounting table 214 is stopped at the nursery box loading position and made to stand by.

When the seedling-raising box M is loaded and placed on the seedling-raising-box mounting table 214, the seedling-raising-box transfer device 210 applies a driving force from the drive source 215 via the gears 215A and 212A to the drive shaft 212.
Rotate. As a result, the nursery box transport device 210 is
The nursery box mounting table 214 is moved to convey the nursery box M from the nursery box loading position to the water injection position. By the way, when the feeding position of the seedling raising box and the pouring position of the nursery box are made to coincide with each other, this carrying step is omitted.

When the nursery box mounting table 214 is stopped at the water injection position, the air cylinders 232 and 233 of the water injection device 230 extend the piston shafts and press the pressing plate 234 against the nursery mat N of the nursery box M. The seedling raising mat N of the seedling raising box M is compressed and the air in the pores is removed. In this state, the water injection pipe 235
The water injection is started from and the air cylinders 232 and 233 start to contract the piston shaft. Along with this, the seedling-raising mat N of the seedling-raising box M restores the initial state and sufficiently takes in water into the pores. The water injection by the water injection pipe 235 is stopped when the pressing plate 234 is separated from the seedling raising mat N of the nursery box M.

When the water injection is completed, the nursery box transportation device 210
Again applies a driving force from the driving source 215 via the gears 215A and 212A to rotate the driving shaft 212. As a result, the nursery box transporting device 210 moves the nursery box placing table 214 and transports the water-filled nursery box M from the water injection position to the seeding position.

When the seedling box mounting table 214 stops at the seeding position, the seedling nozzle holding bracket 254 causes the seedling nozzle holding bracket 254 to move by applying a driving force from the drive source 256 of the seeding means 250 to the drive shaft 255 via the gears 256A and 255A.
