The seedlings grown in the above-mentioned seedling raising trays or continuous collection pots that can be pulled out in rows are labor-saving for raising seedlings and planting, but they are small seedlings with a leaf sheath diameter of 2 to 3 mm, so the growth at the initial stage of planting is unstable. However, there is a problem that it takes a long time to harvest. This is one of the causes of destabilizing the production during abnormal weather such as heavy rains in recent years and extreme heat in summer, even in the cultivation using seedling raising trays or continuous collection pots that can be pulled out in rows, Growing and using large seedlings instead of small seedlings is considered as a means to stabilize production.

As methods for raising large seedlings, there are methods to reduce the seeding amount per seedling raising tray and continuous collection pots that can be pulled out in rows, and methods to replant small seedlings into a large-capacity seedling raising pot, etc. It is difficult to secure labor saving in collecting and growing large seedlings and planting them in the field, and it is not widely used as a cultivation technique for root deep leeks. As a prior art relating to large seedling raising, there is a technique disclosed in Japanese Patent Laid-Open No. 6-90626, but since it is a method using hydroponic method, it is not introduced in Nebuka spring onion production area which does not use hydroponic method for raising and cultivating seedlings. difficult. Further, as a prior art relating to secondary seedling raising, there is a technique disclosed in Japanese Patent Laid-Open No. 7-308125, which is a technique premised on hydroponic cultivation such as hydroponic leaf onions, and is used for cultivating root deep leeks. It is not possible.

A row of row-pullable continuous collection pots (264 holes) used for cultivating root deep leeks were seeded with 528 seeds of root deep leeks in 2 holes each, 528 seeds, and seedlings were grown for 28 days to grow seedlings 6 From the opening 5 formed by raising the side wall 3 of the long-sized seedling raising container 1 (width 4.2 cm) made of a flexible polyethylene sheet of about 0.15 mm using the side wall raising device 13, Coated compound fertilizer containing 14%, 12% phosphoric acid and 14% potassium and having an elution period of 100 days was not supplied per 1 m in length, 3 g, 6 g, commercially available seedling cultivation soil or 200 ml per m in length was supplied. Small seedlings 6 were placed in each long seedling-growing container 1 so that the distance between the plants was about 5 cm. After transferring the small seedlings 6 to the long-sized seedling-growing container 1, fertilization management was performed three times a day (8:00, 12:00, 16:00) while irrigating with about 1.5 L per square meter of the nursery bed, and secondary seeding was performed. 63 days after the start of secondary seedling, the diameter of leaf sheath was measured. The results are shown in Table 1.

From the results of Table 1, commercial culture soil or perlite is 200 ml per 1 m of a long-sized nursery container, and a coated compound fertilizer containing 100% of Chisso, 14% of phosphoric acid and 14% of potassium and having an elution period of 100 days is used for a long-sized nursery container. Large seedlings with a leaf sheath diameter of 6 mm or more can be grown by putting small seedlings 6 in a long seedling raising container 1 supplied at 6 g per 1 m and performing secondary seedling three times a day while watering about 1.5 L per square meter of seedling bed. In the long seedling raising container 1 to which the coated compound fertilizer was supplied, roots were developed at the inner bottom of the container at the time of investigation of the leaf sheath diameter and were in a belt-like state (belt-like root-joined seedling 30).
After investigating the diameter of the leaf sheath, while taking out the belt-shaped root-connected seedling 30 from the opening 5 of the long-sized seedling raising container 1, the seedling take-up device 26 wound the disc 28 and set it in a field. The seedlings were placed on the seedling raising box mounting frame 20 of the transplanter 18, and the belt-shaped root-connected seedlings 30 were pulled out by rotating the disk 28, and were planted in the field. It was possible to plant in the field by the same procedure.

As shown in FIG. 11, the seedlings 6 of seeds of root deep leeks, 528 seeds, 2 seeds per well, were sown in a row of continuous collection pots (264 holes) used for cultivating root deep leeks for 2 days as shown in FIG. The water absorbent sheet for raising rice seedlings cut into a width of 2 cm after being placed on the seedling raising box placing frame 20 of the continuous collecting pot body seedling transplanting machine 18 installed on the side wall start-up device 13 of the long seedling raising container 1 The seedlings 6 pulled out in a row from the continuous collecting pot seedling transplanting machine 18 were put in one after another while being spread on the inner bottom part, and the seedlings 6 were put into the long seedling raising container 1 and pulled out to the seedling raising bed.
This was repeated, and the long seedling-growing containers 1 of about 10 m in length containing the small seedlings were arranged side by side in 6 rows without gaps, and then perlite was sprayed to the edge of the seedlings.
After transferring the small seedlings 6 to the long-sized seedling container 1, raise water 3 times a day (8:00, 12:00, 16:00) with water mixed with water-soluble gardening fertilizer with a total nitrogen content of about 15 to 2000 to 4000 times. Secondary seedlings were raised in a form of fertilization management while irrigating with about 1.5 L of water per square meter of floor.
59 days after the start of the secondary seedling, the seedlings were planted in a field, and the seedlings at this time had roots developed at the inner bottom of the long-sized seedling container 1 and the roots of a plurality of seedlings were connected in a belt-like shape (belt-like shape). Root-connected seedling 30).
At the time of planting, the belt-shaped root-connected seedlings 30 are pulled together from the nursery bed together with the long-sized seedling-growing container 1 row by row, and the belt-shaped root-connected seedlings 30 are taken out from the opening 5 of the long-sized seedling-growing container 1 while taking up a seedling winding device. It is wound on a disk 28 at 26, placed on the seedling box mounting frame 20 of the continuous collecting pot seedling transplanter 18 set in the field, and the disk 28 is rotated to pull out the belt-shaped root portion connected seedling 30. , Planted in the field. For comparison, row-drawable continuous collecting pot seedlings 19 that had been raised by conventional techniques for 88 days were also planted in the field on the same day by the continuous collecting pot seedling transplanter 18.
After planting, fertilization is managed according to the customary technique (additional fertilizer is added once in the half of the area where the secondary seedlings were raised), harvested 144 days after planting, and root cutting, leaf cutting, and peeling are performed to achieve the normal shipping form. After peeling, the preparation weight was investigated according to the shipping standard. The results are shown in Table 2.

From the results of Table 2, when the belt-shaped root-connected seedling 30 secondary-grown in the long-length seedling container 1 was wound by the seedling winding device 26 to be collected and planted by the continuous collecting pot seedling transplanter 18, it is a customary practice.
