Abstract

<P>PROBLEM TO BE SOLVED: To provide a cultivation method for hygienically efficiently working without dropping culture soil when using a raising seedling tray corresponding to conventional mechanized sowing and grafting young seedlings, relieving plant density of plant bodies, and contributing to equation and suppression of useless development of seedling growth. <P>SOLUTION: This cultivation method using the raising seedling tray comprises superposing without space row cell tray units cut by every row, on conventional lattice-like raising seedling main body cell trays, and filling culture soil followed by cultivating until grafting work. Grafting work is performed by removing the row cell tray units from the main body trays, and after the grafting work is finished, the plant bodies are put at arbitrary intervals in the main body trays according to the seedling age and cultivated. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a seedling tray for grafting seedlings and a cultivation method thereof.

  A seedling tray in which a plurality of concave portions are provided by a method such as vacuum molding using a sheet of a rectangular synthetic resin material, and these concave portions are used as cells, respectively, and the seedlings are filled with the soil to raise seedlings is known. .

  Such a tray is formed in such a manner that recesses are connected therein, and the entire shape of the tray is rectangular. Then, the soil that fills the recesses of each cell is filled with culture soil and mechanically sown to grow germinated seedlings, and seedlings from this tray are formed at the stage where root pots with roots stretched to the extent that the soil is not separated are formed. This is very useful in terms of workability. As for raising seedlings of solanaceous fruit vegetables, there is a tendency to use a molded cell tray for raising seedling as described above from the viewpoint of labor saving and rationalization. In the seedling grafting of solanaceous fruit vegetables, grafting work is performed at the stage (seedling age) grown by the cultivation in the cell.

  In recent years, automatic seeding of vegetable seedlings has become popular. The cell tray is also a seedling tray suitable for machine attachment. However, automatic grafting machines are expensive for small and medium-sized seedling establishments, and the nature of plants is uneven due to the cultivation conditions and weather, making it difficult for everything to be automated. Therefore, seedling grafting by hand is also performed in many situations.

  When grafting by hand, rootstock seedlings were extracted from the seedling tray with the soil and root pots visible for each cell. Alternatively, it was processed as a seedling tray sown and cultivated.

  However, even if the whole cell was extracted, the seedlings of the solanaceous vegetables were slow to form root pots even when they reached the grafting stage (seed age), and the soil was spilled and unhygienic and inefficient. Moreover, when the time when the root pot was formed, it had the disadvantage of becoming a chief seedling.

  In addition, regarding the seedling management after grafting, the planting density is high until transplanting, and the speed at which the growth point part goes upward is faster than the formation of the root pot. When I waited, I had the disadvantage of becoming a chief seedling.

  Therefore, the present invention is found in grafting work using a conventional molded seed tray for raising seedlings, especially when grafting vegetable seedlings such as fruit vegetables of the solanaceous family, the formation of root pots is slow even if the whole cell is extracted, The problem of being spilled and unsanitary and inefficient.

  In addition, if the time when the root pot is formed before grafting, it has the disadvantage of becoming a chief seedling.

  Also, regarding seedling management after grafting, the planting density is high until transplanting, and the speed at which the growth point part goes upward is faster than the root pot formation, so the time when the root pot is formed If you wait, you will become a chief seedling.

  It is intended to eliminate the above-mentioned drawbacks and problems, and when processing grafts, etc., work hygienically and efficiently without spilling the soil, and to reduce the planting density of the plant body, An object is to provide a molded cell tray unit for growing seedlings by row that contributes to uniform growth of seedlings and suppression of the length of the seedling, and a cultivation method thereof.

  In order to achieve the above object, the seedling tray according to the present invention comprises a row seedling tray unit in which the number of cells filled with the soil is connected by the number of cells in the vertical direction or the horizontal direction of the main body tray to be stacked in a lattice shape. And, this tray is set in each row on the main body tray.

  In the following, the present invention will be described in detail based on specific embodiments shown in the drawings. As row seedling raising seedling trays for grafting seedlings, row-like seedling raising tray units 2 are set in a row in a conventional seedling-forming cell tray 1 for raising seedlings. (Fig. 1 and Fig. 2) After setting, the tray is filled with soil and mechanical seeding of rootstock seeds. The state before the stage (seedling age) for grafting in the middle of cultivation is shown in FIG.

  When working separately with the cultivated hogi H and grafting, etc., the row-shaped seedling tray unit of the grown rootstock is taken out from the main body tray 2. Multiple rootstocks can be pulled out at once, which is efficient and contributes to hygienic work without breaking the soil and root pots in the cell. (Fig. 4)

  The curing period and the growing period after the grafting work is completed, the row-shaped seedling tray unit 1 is set in the main body tray 2 at an arbitrary interval according to the size of the plant body, and the planting density is reduced. Contributes to uniform growth and suppression of length. (Fig. 5)

  Further, before reaching the grafting operation, the row-shaped seedling cell tray units may be separated according to the growth of the seedlings to reduce the planting density, thereby contributing to uniform growth of seedlings and suppression of the length of the seedlings.

  Since the cutting of the rootstock is performed with razor, scissors, etc., the row seedling cell tray unit is easier to cut when it is in one row.

It is a perspective view of a row seedling seedling cell tray unit and a main body cell tray before setting It is a perspective view of the cell tray of the state before seeding after setting. It is a perspective view of a cell tray during rootstock cultivation before grafting work It is a perspective view of the row-like seedling cell tray unit during grafting work It is a perspective view of the cell tray during grafting seedling breeding
