Further, the auxiliary feed belt 5a is configured such that the drive wheel 50 is formed to have a slightly larger diameter than that of the feed belt 4a so that the feed amount is large, and the auxiliary feed belt is attached to the lower mat seedling fed by the feed belt 4a. The upper mat seedling sent in 5a can be auxiliaryly fed in a state where the mat seedlings are tightly joined to each other without creating a gap. This prevents the planting and clogging, etc., and makes it possible to connect good planting operations.

A seedling detection sensor 7 is provided on the seedling mounting surface 3a between the feed belts 4a, 4a below the auxiliary feed belt 5a.
Is provided to accurately detect the presence or absence of mat seedlings, and when it is detected that no seedlings are present, an alarm is issued before the seedlings run out to encourage the supply of seedlings. Next, the length relationship between the seedling mounting table 3, the seedling feeding mechanism 4, and the auxiliary seedling feeding mechanism 5 will be described.

The overall length L of Naeno board 3 as shown in FIG. 7, the seedling detection sensor 7 when prompted detected and seedling supply passage of the mat seedling M ₁ rear, the next order in the upper part When two mat seedlings of the mat seedlings (M2, M3) are formed in a length that can be placed, and when the mat seedlings M3 are supplied to the upper end of the seedling mounting surface 3a, the auxiliary feed belt 5a is set to the above-mentioned state. In this state, the length is set so as to be in contact with both the rear part of the lower mat seedling M2 and the upper mat seedling M3 to perform the feeding action.

Then, as shown in FIGS. 6 and 7, the lower mat seedling M1 is transferred while being scraped by the planting operation, and the rear portion passes through the seedling detection sensor 7 between the feed belts 4a, and the next step. When the mat seedlings need to be replenished, a mating margin for stably supplying and mounting the entire length of the next mat seedlings M2 and M3 is formed in the preliminary stacking margin L1 of the seedling mounting table 3. auxiliary feed belt 5a when the seedlings M3 is replenished with mat seedling M _2, as well as good transport both further contact with the front portion of the mat seedlings M3, lower mat seedlings M
1 can also be transferred by the pressing force of the transfer of the feed belt 4a and the mat seedlings M2 and M3.
M3 can be satisfactorily transported by the feed belt 4a and the auxiliary feed belt 5a, respectively, so that planting can be smoothly performed while preventing stock-out and the like.

The planting apparatus 2 constructed as described above performs the planting operation with the mat seedlings M1 and M2 placed on the seedling mounting table 3 as shown in FIG. Is fed by the auxiliary feed action of the auxiliary feed belt 5a, and the lower mat seedling M1 is reliably fed at a constant speed by the feed belt 4a, so that the fixed amount scraping by the planting claws 2b can be carried out well.

Next, when the number of the mat seedlings M1 in the lower stage decreases and reaches the seedling detecting sensor 7 shown in FIGS. 7 and 1, when the next matting seedling M3 is supplied to the preliminary mounting allowance L1 shown in FIG. The front portion of the seedling M3 is engaged with the auxiliary feed belt 5a, so that the initial seedling feeding can be accurately performed.
