Description

  The present invention relates to a large seedling breeding method for stable production of deep root onion, and a long seedling storage container therefor, an apparatus and a winding device therefor, and more specifically, a rowable continuous drawable continuous row used for cultivating deep root onion Recovery of seedlings by labor-saving by transferring the small seedlings of about 2 to 3 mm in diameter of leaf sheath (maximum diameter of central part of leaf sheath) grown in collective pots to a flexible long-sized nursery container and secondarily raising seedlings The present invention relates to a method for cultivating large seedlings having a diameter of sheath sheath of 6 mm or more, which can be planted, and a long-sized nursery container therefor, a device for placing continuous collective potted seedlings, and a winding device.

  Originally, in the seedling raising of root deep leeks, it was sown directly in the seedling raising seedling, and when the leaf sheath diameter became about the thickness of a pencil, it was used as a seedling to dig up from the seedling raising seedling and planted in the field (following, ground seedling) .

  Ground floor seedlings require 40 to 60 hours of working time per 1000 square meters of field to dig up the seedlings and plant them in the field, and labor saving has been required.

  For this reason, there is a labor-saving technology for raising seedlings in a raising seedling tray for root depth leeks of about the size of a rice seedling raising box (about 30 cm × about 60 cm) or a continuous collective pot that can be pulled out in rows and planting with dedicated planting machines and instruments. It has been developed and widely used for root deep leek cultivation in combination with ground seedlings or alone.

  Seedlings grown in the above-mentioned nursery trays and row-drawable continuous collective pots are capable of saving up seedlings and planting while saving labor, but since they become small seedlings with a leaf sheath diameter of about 2 to 3 mm, the growth in the initial planting initial stage is unstable. There is a problem that the time to harvest becomes long. This is one factor that destabilizes production during abnormal weather conditions such as recent torrential rain and intense summer heat, and also in cultivation using a nursery tray and a continuous collective pot that can be pulled out in rows. Cultivating and using large seedlings instead of small ones is considered as a means to stabilize production.

  As a method of growing large seedlings, there are a method of reducing the seeding amount per row of continuous collecting pots capable of pulling out a row or a row, and a method of secondarily raising seedlings by replanting small seedlings into a large-capacity seedling pot etc. It is difficult to ensure labor-saving for collection of planted large seedlings and fixed planting in the field, and it has not been widely used as a cultivation technology for deep-leaf green onions. Although there is a technique disclosed in Japanese Patent Application Laid-Open No. 6-90626 as a prior art concerning large seedling breeding, since it is a method using a hydroponic method, the introduction in root deep green onion producing areas where hydroponic method is not used for difficult. Moreover, although there exists a technique shown by Unexamined-Japanese-Patent No. 7-308125 as a prior art regarding a secondary raising seedling, it is a technique on the assumption of hydroponic cultivation, such as a hydroponic leaf green onion, used for cultivation of root deep green onion It is not possible.

  The present invention has been made in view of the above circumstances, and provides a method for cultivating large seedlings which can be harvested and set planted with energy saving in cultivation of root deep green onion.

  As a result of intensive studies to solve the above-mentioned problems, the inventor of the present invention has made it possible to use flexible raw materials for small seedlings grown in a row-drawable continuous collective pot used for cultivating root deep leeks. After feeding the culture soil mixed with slow-acting fertilizer, while being drawn into a long seedling container having side walls on both the bottom and the bottom of the container, the soil is placed in a movable state to the nursery bed, and the soil is always moist Thus, by conducting secondary raising while conducting irrigation several times during the day, it is possible to grow large seedlings which can be recovered and set in a labor-saving manner.

  The long seedling raising container used in the present invention is entirely made of a flexible synthetic resin, and the side walls of the container bottom and the both sides connected without a gap have elasticity in the direction to fall inward, and small seedlings and culture soil enter. And in the state before use where the side wall is not supported by instruments etc., the angle inside the joint between each side wall and container bottom is near 0 or 0 degree, and both side wall and container bottom are similar In order to be able to raise the side wall in use, the side wall bottom portions in contact with the bottom surface of the container are joined to the respective ends of the bottom surface of the container. When putting in small seedlings and culture soil for use in secondary nursery, start up the side walls on both sides of the long nursery container, and put small seedlings and culture soil in the opening of the container. is there.

  The large seedlings obtained by secondary raising by the above-mentioned method develop roots on the bottom of the inside of the container for long-length seedlings, and keep the interval at the time when they are inserted into the long-growing containers. It becomes a belt-like root portion joint seedling where roots become entangled belt-like, and a plurality of grown large seedlings can be wound up and collected like a series of belts and planted in a field.

  Since the inside of the long-sized seedling raising container used in the present invention is not separated by a partition or the like and is connected, it is raised by continuous collective pots which can be pulled out in a row at the opening formed by raising the side walls on both sides. By putting small seedlings and culture soil one after another, it is possible to continuously spread and change between plants, and it is possible to carry out replanting at the time of secondary raising seedlings laborsavingly.

  In order to use a long-sized nursery container made of a flexible synthetic resin, when collecting grown large seedlings after secondary nursery, the long-term nursery container of the nursery bed is pulled up from the end, so that the worker's own It is possible to save the grown large seedlings one after another without any change in position. After use, the elongated nursery container can be wound up and collected, and can be stored compactly.

  When secondary raising seedlings of root deep green onion are carried out according to the method of the present invention, since a plurality of large seedlings in an open state are intertwined with roots developed at the bottom, they become belt-like root connected seedlings connected in a belt shape. After raising the seedlings, they can be taken up and collected, and can be planted in the field in a labor-saving manner using a continuous collecting pot seedling transplanting machine.

  By using large seedlings according to the method of the present invention, the period from planting to harvesting is shortened compared to the case of using small seedlings grown in a nursery pot or a continuous collective pot that can be pulled out in a row, so Even when planting in July, when growth in mid summer is stable compared to May planting in the fall harvest cropping type, it becomes possible to harvest in the autumn when high unit prices can be expected.

  ADVANTAGE OF THE INVENTION By this invention, utilization of the large seedling in the production field of root deep leek becomes easy by providing the method which can grow the large seedling which can collect | recover a seedling efficiently and can carry out planting labor-savingly. Therefore, the present invention greatly contributes to the stable production of deep-seaweed leek.
