Is provided, and the fertilizer effect control-type fertilizer lump 10 is supplied between 5 layers of the lower floor soil soil and 5 layers of the upper floor soil soil.

[0013]

[Operation] Next, the operation will be described. When the bed soil 5 in which the fertilizer effect control-type fertilizer lump 10 is mixed is supplied to the supply hopper 19 of the bed soil supplying device 18, and the seedling raising container 1 is supplied to the transfer table 15 in this state, the bed soil supplying device 18 When it passes below, it receives the supply of the bed soil 5 in which the fertilizer control type fertilizer lump 10 is mixed,
Next, the excess soil is scraped off by the rotating and leveling brush 21 to be leveled, and the supply of the floor soil 5 is completed. Further, since the rotary leveling brush 21 cannot scrape off the soil inside the front wall 29 and the rear wall 28 of the seedling raising container 1, the corner soil remains in an arc shape, but this is removed by the corner pressing device 30. Therefore, the seeds 6 and the fertilizer control-type fertilizer lump 10 are prevented from moving and gathering in the corner.

Next, the seedling-growing container 1 reaches below the irrigation device 50, is irrigated from the irrigation hole 52 of the irrigation pipe 51, receives the seeds 6 below the seed feeder 60, and below the soil cover feeder 64. The seeds 6 are thinly covered with the soil 7,
Sowing 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. In addition, especially in sowing of paddy rice, seedling raising container 1
Seedlings are transplanted in a field using a rice transplanter, but since the fertilizer control type fertilizer lump 10 is mixed in the bed soil 5, fertilizer can be fertilized at the same time even with a normal rice transplanter, Topdressing work can be largely omitted, and the work can be reduced and the fertilizer cost can be reduced. In addition, since the fertilizer control type fertilizer lump 10 is mixed in the floor soil 5, it does not flow out compared to surface spraying in the field, and has a high environmental conservation effect such as water quality, and the fertilizer absorption is reliable. From this point as well, the total amount of fertilizer applied can be reduced, and the fertilizer cost can be reduced. 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 growth even in cultivation in non-implanted transplant fields where lateral fertilization is difficult.

That is, in the field of uplifting which is raised after the fertilizer is applied,
There is fertilizer in all the layers where the roots of the seedlings are stretched, but in the non-implantation transplant field, the fertilizer is sprayed on the surface, so there is no fertilizer in all the layers of soil,
Further, in uncultivated fields, lateral row fertilization to the deep side of the lateral row of the seedlings is difficult, so the growth was not good, but the present invention, when transplanting the seedlings, the fertilizer necessary for the growth of the seedlings Since it is transplanted to the field along with it, it is possible to omit additional fertilization work, reduce work, reduce fertilizer costs, prevent fertilizer runoff, and conserve the environment such as water quality. Further, compared to mere nitrogen fertilizer, there is no burning of fertilizer, there is no obstacle even when entwining the fertilization-control-type fertilizer mass 10 in the root, and fertilizer absorption is reliable, and a uniform fertilizer effect can be obtained even in so-called uneven soil fields. .

In the second embodiment shown in FIGS. 9 to 12, since the fertilizer application device 70 sprays the fertilizer control type fertilizer lump 10 to apply fertilizer, the fertilizer is applied to the bed soil 5 in advance. The work of mixing the adjusted fertilizer block 10 is unnecessary. Further, since the fertilizer application device 70 can mechanize the fertilizer application,
Very easy to work with. In addition, since the feed amount of the fertilizer effect control-type fertilizer mass 10 can be adjusted by adjusting the position of the sliding contact brush 76 with the dial 78 of the fertilizer application device 70, the optimum amount can be applied for each variety.

A transplanter such as a rice transplanter cuts mat-shaped seedlings with a nail and transplants them into a field, but the fertilizer control type fertilizer lump 10 is surely planted in the field together with the seedlings. Also,
In the third embodiment of FIGS. 13 to 15, the soil 5 is supplied, the fertilizer is applied by the fertilizer application device 70, the seed is then seeded, and then the soil is covered. The effect-adjustable fertilizer mass 10 can be surely brought into the field.
Further, if a large amount of the fertilizer control-type fertilizer lump 10 is sprayed, the water penetration may be affected, but if the bed soil 5 is sufficiently irrigated before fertilization, the water penetration is not affected.

Therefore, in the fourth embodiment of FIGS. 16 to 18, another bed soil supplying device 18 is provided in front of the bed soil supplying device 18, and between the bed soil supplying device 18 and the bed soil supplying device 18. Since the fertilizer application device 70 is provided and the fertilization control type fertilizer lump 10 is supplied between the lower floor soil subterranean soil 5 layers and the upper floor soil subterranean soil 5 layers, the fertilization control type fertilizer lump is provided together with the seedlings. It is possible to reliably bring 10 into the field, and to prevent runoff due to irrigation during seedling raising.

[0019]

[Effect] According to the present invention, the bed soil 5 is supplied from above to the seedling raising container 1 being transferred, and the seeds 6 are supplied to the upper surface of the bed soil 5, and the seeds 6 are supplied.
In the seeding and raising method, in which the soil 7 is supplied and seeded on the upper surface of the seedling, the seedlings are raised in the seedling raising container 1, and then the seedlings are raised for a certain period of time and transplanted to the field. Since the fertilizer application method is a seeding and raising method using a seedling raising container in which a fertilization-controlling fertilizer lump 10 whose amount can be adjusted is mixed, there is little additional fertilization after transplanting the raised seedlings, and the additional fertilization work is reduced. And reduce fertilizer costs. Topdressing in the field requires a fertilizer applicator capable of topdressing (side row fertilizer appli- cation), but this can be eliminated. In addition, since the seedlings are transplanted together with the fertilizer, the fertilizer is distributed near the root, and the side-row fertilizer application device can be omitted. Further, since the fertilizer is on the edge, it is possible to grow the seedlings even in a field with uneven soil strength. In addition, compared to spraying fertilizer on the surface of transplanted soil, the fertilization control type fertilizer mass 10 can be located below the roots of the seedlings, the absorption efficiency can be increased, and the fertilization effect can be sufficiently expected. Compared to surface spraying, less fertilizer application is required,
It also reduces fertilization costs. In the case of paddy rice seedlings, 5 soil
Since the fertilizer control-type fertilizer lump 10 is mixed in, it becomes the same as when the fertilizer is applied at the same time even with a normal rice transplanter, and the additional fertilization work can be largely omitted, the work is reduced, and the fertilizer cost is reduced. The amount of fertilizer can be reduced, it does not flow out compared to spraying it on the surface, it has a high environmental conservation effect such as water quality, and the fertilizer can be absorbed reliably. The effect of improving initial growth is achieved even in cultivation in a non-implanted transplanted field where lateral row fertilization is difficult to carry out in the deep part of the lateral row of seedlings. Also, fertilizer control type fertilizer lump 1
Elution of 0 for a period of about 30 days at a soil temperature of 25 ° C is minimal, and if a product that elutes for about 70 days or longer is used, it will not be heated and will not require heating and seedling equipment. Since the fertilizer component is eluted after the middle period, it is efficiently absorbed and stable and high yield can be achieved.
