Description

[Detailed Description of the Invention] The present invention is characterized in that the roots of the seedling group are intertwined so that the nursery staff is continuous at the top, making it very easy to handle such as setting in a rice transplanter. This invention relates to a method of sowing seeds in seedling boxes for obtaining mat-like continuous seedlings that can be well separated and planted.

Conventionally, in consideration of the thickness of covering soil after sowing, the bedding was supplied to an extent that did not cover the upper edge of the seedling box, and the upper surface after being supplied with the bedding was leveled using a rotating brush. Therefore, the bed area near the side wall of the seedling nursery box is not a fan flat but a sloped surface, and as a result, the seeds sown there may fall off, causing variations in the spacing of the seedling rows throughout the seedling nursery box. It became. The present invention aims to provide a method for sowing seeds in a seedling nursery box, which allows seeds to be well scraped onto the upper surface of the soil near the peripheral side wall of the seedling nursery box. The method of sowing seeds in a seedling nursery box of the present invention includes a bed guard feeding step in which a bed guard is supplied to the upper edge of the seedling nursery box, a scraping step in which the bed soil above the upper edge of the seedling nursery box is removed, and a top green of the seedling nursery box after scraping. The method is characterized by comprising a step of iron-fixing the upper frame to the top frame, a sowing step of supplying seeds to the bed soil of the seedling-raising box after the upper frame is attached, and a covering step of covering the seedling-raising box with soil after sowing.

That is, since the bedding is supplied to the upper edge of the seedling nursery box and the top surface is leveled by scraping, the upper surface of the bedding near the peripheral side wall of the seedling raising box does not become a sloped surface. Seeds can be scraped at predetermined intervals on the top surface of the bedding near the peripheral side wall of the seedling raising box, and it has become possible to prevent variations in the spacing between the growing seedlings.

Embodiments of the present invention will be described below based on the drawings.

First, to explain the structure of the seedling raising device used in the method of the present invention, reference numeral 2 is a rectangular seedling raising box having an upright circumferential side wall 1, and the bottom plate 3 has a groove bent in a wave shape and closing upward. Shape-shaped seedling beds 4... and groove-shaped ventilation parts 5 that close downward are alternately formed on the front and back surfaces thereof, and the peripheral side walls 1... Floor part 4...
The nursery nurse A housed inside the nursery bed is formed at a height that is continuous in the shape of a mat at the upper part.

In other words, the peripheral side wall 1... is flush with the top surface of the soil A stored in the seedling box 2, which is spread over the opening of each seedling bed section 4... It is composed of Each of the seedling beds 4 is constructed so that the upper part thereof becomes wider in the middle. Reference numeral 6 denotes an upper frame placed on the peripheral side wall 1 of the seedling growing box 2, and this is detachable from the seedling growing box 2.

3a... are holes that are continuously or intermittently bored in the bottom of each of the seedling beds 4 along the longitudinal direction of the bottom.

Bedroom operator A of the method of the present invention for a seedling nursery device configured as described above
The procedure for storing the seeds and the procedure for sowing to the bedding staff A will be explained based on FIG. 3. While the seedling raising box 2 is being conveyed in one direction by the conveyor B, soil A is first poured into the seedling raising box 2 from the bedding worker supply hopper C until it reaches the upper green area of the seedling raising box 2, and then inside the seedling raising box 2 using the cutting tool C2. Level the bed soil A so that its upper surface is flush with the upper edge of the peripheral side wall 1 of the seedling box, and then attach the upper frame 6 to the seedling box 2 at a temperature of 7° C. Arriving and water sprinkler C3
Sprinkle water with the seedling hopper C4 and seedling bed section 4...
The soil is sown in a falling row along the top, and then covered with soil by falling from the soil covering hopper C5, and then watered with a water sprinkler C6.
