への空気の出入りが可能となっている。Reference numeral 2 indicates a frame. The pedestal 2 includes a stand 22 on which a tray 6 containing a medium 4 for growing seedlings is placed, and legs 24 that support the stand 22. The leg portion 24 is connected to the base portion 22
A plurality of legs 2 extending downward from the corners or ends of the
6, and a side plate 28 provided so as to surround this leg 26.
The internal space 8 of the pedestal 2 is defined by the base portion 22 and the leg portions 24 that constitute the pedestal 2. A gap 30 communicating with the outside is formed at the upper and lower ends of this internal space 8, and the internal space 8 of the frame 2 can be viewed from the outside.
Allows air to enter and exit.

られている。Further, two convection heat radiators 10 are arranged in parallel approximately in the middle of the internal space 8 of the frame 2. This convection radiator 1
0 creates natural convection, with air flowing in from the bottom and out from the top. The heat source is steam, hot water, etc. Further, above the convection radiator 10, two punched metal plates 12 for air rectification are provided vertically with an interval therebetween so as to partition the internal space 8 in the horizontal direction.

地４が加温されるのである。Next, heat is radiated from the convection radiator 10. This convection radiator 1
Air flows in from the bottom and is heated by the natural convection generated by the zero, and air flows out from the top. Therefore, in this embodiment, in the internal space 8 of the pedestal 2,
Natural convection occurs, with air flowing from below to above. That is, the air flows into the internal space 8 of the frame 2.
It flows in from the lower end of the interior space 8, is heated by the convection radiator 10, rises, passes through the punched metal plate 12, and flows out from the upper end of the internal space 8. Incidentally, when rising, the air flow is rectified by the punched metal plate 12 and rises toward the lower surface of the base portion 22 of the pedestal 2. Then, the heated air flows to the upper part of the internal space 8 and heats the upper part of the internal space 8, and the heat is transferred to the seedling growing medium 4 in the tray 6 via the platform 22. 4 is heated.
上記のようにして育苗用培地４を加温して育苗を行う際
、トレイ６の底は架台２の台部２２の上面に接している
ので、トレイ６の底から苗の根が延びることはない。When growing seedlings by heating the seedling growing medium 4 as described above, the bottom of the tray 6 is in contact with the top surface of the stand 22 of the pedestal 2, so the roots of the seedlings will not extend from the bottom of the tray 6. do not have.
従って、育苗後にトレイ６を動かす際にも、トレイをそ
のまま搬送台車や回転棚に載せることができる。Therefore, even when moving the tray 6 after raising seedlings, the tray can be placed on the conveyor cart or rotating shelf as it is.
なお、架台２の脚部２４に車輪等を装着すれば、架台２
ごと移動することも可能となる。Note that if wheels or the like are attached to the legs 24 of the pedestal 2, the pedestal 2
It is also possible to move the whole thing.
