[0011]

[Operation] Next, the operation will be described. When the seedling-growing container 1 is supplied to the transfer table 15, the lower bed soil layer 8 is supplied when it passes below the floor soil supply device 18 on the front side, and then the bed soil supply device 18 on the front side is supplied. When passing, the upper soil layer 9 is supplied, and the soil is squeezed by the squeezing roller 26. The excess soil is scraped off by the rotating brush 28 to be leveled, and the supply of the soil 5 is completed. Next, the seeds 6 are sown on the top surface of the soil 5,
The seed 6 is thinly covered with the soil 7, and the seeding is completed. In this case, since the bed soil 5 is mixed with the fertilization effect control type fertilizer lump 10 capable of adjusting the elution timing and the elution amount of the fertilizer component, the additional fertilization after transplanting the raised seedlings is small, and the additional fertilization work is required. Reduce fertilizer costs.

Therefore, the floor soil 5 has at least two layers, the lower floor soil layer 8 of the floor soil 5 is mixed with the fertilizer control type fertilizer lumps 10, and the upper floor soil layer 9 is formed of the usual soil. Since the fertilizer is not mixed, the root generated from the seed 6 is sought downward for the fertilizer control type fertilizer lump 10 so that the root is well rooted and the growth is good. In addition, as compared with spraying fertilizer on the surface of transplanted soil, a fertilizer-controlled fertilizer block 10 below the roots of seedlings.
Since it is located, the absorption rate is high, fertilization effect can be expected sufficiently, the amount of fertilization applied is smaller than that of ordinary surface spraying, and the cost is reduced. Next, in the case of paddy rice seedlings, seedlings are raised in a seedling raising container 1 and transplanted to a field by a rice transplanter, but since the lower floor soil layer 8 contains a fertilization control type fertilizer block 10. ,
Even with a normal rice transplanter, fertilizer can be applied at the same time as seedling transplantation, and the additional fertilization work can be greatly omitted, and the work and fertilizer cost can be reduced.

Further, since the fertilizer control type fertilizer block 10 is mixed in the lower soil layer 8, it does not flow out as compared with spraying it on the surface and has a high effect of environmental conservation such as water quality. The fertilizer can be absorbed surely, and the fertilizer cost can be reduced from this point as well. In particular, the use of a fertilizer control type fertilizer lump 10 containing nitrogen as a main component of coated urea, which elutes at a soil temperature of 25 ° C. for about 30 days is minimal, and then elutes for about 70 days or more. Improves initial growth even in cultivation in non-implanted transplant fields where lateral fertilization is difficult. Therefore, the transfer base 1 placed on the floor by the supporting legs 16 formed long in the transfer direction and provided at a predetermined interval.
Since a plurality of bed soil supply devices 18 are arranged in series above the position 5, the heterogeneous bed soil 5 is supplied to the supply hoppers 19 of the bed soil supply devices 18, respectively, and seedlings are raised in this state. When the container 1 is supplied to the transfer table 15, the bed soil 5 can be supplied to the seedling raising container 1 in an ideal layer arrangement.

That is, as described above, the lower soil layer 8 of the soil layer 5 mixed with the fertilizer control type fertilizer mass 10 and the upper soil layer 9 of the soil layer 5 not containing normal fertilizer. Not only can it be easily mechanized, but the lower soil layer 8 is a large-grained red jade soil, and the upper soil layer 9 is a medium- and small-sized soil such as red jade soil and humus soil. Can be supplied in sequence, and soil supply work can be easily mechanized to improve workability and also to improve seedling growth. In addition, the floor soil supply device 18 is provided with the same supply hopper 19 at the upper part, the same delivery belt 20 below the supply hopper 19, and the same delivery amount adjusting device 22 at the delivery port 21 of the delivery belt 20. Since the construction is provided, it is possible to mechanize the supply of the multi-layered soil 5 without increasing the production cost. Further, the feeding amount adjusting device 2 is provided at the feeding outlet 21 of the floor soil supplying device 18.
Since it is configured with two, it is possible to subtly distribute the layer thickness, and it is possible to supply soil according to the crop.

However, since the rotary brush 28 is provided in front of the bed soil supplying device 18 which is the frontmost position in the transfer direction of the seedling raising container 1 among the bed soil supplying devices 18 arranged in series, an extra brush is provided. After supplying the bed soil 5, the upper surface of the bed soil 5 supplied to the seedling raising container 1 can be removed and leveled to a predetermined depth, and seeds can be evenly sown. Well, seedling container 1
May be a bowl-shaped bowl 31 as shown in FIG.
When it is fitted into the mounting frame 33 for preventing the tipping over and is supplied to the transfer table 15, the floor soil 5 can be supplied as described above. In addition, a lid member 36 having an opening 34 and a core 35 is placed on the upper surface of the bowl 31 to supply the floor soil 5, and thereafter,
When the lid member 36 is removed, the planting hole 3 for transplantation is placed in the pot 31.
