( Seeding method and harvesting method using the seeder according to the present invention) The seeding method for leaf vegetables using the seeder according to the present invention and the method for harvesting the leaf vegetables sowed by the method are as follows.
First, seeds of leafy vegetables are sown in parallel with the pods in a sowing step. In the following examples, an example of seeding using a seed tape is shown, but a conventional seeding machine that does not use a seed tape can also be used.
Next, in the tape placement step, a mesh tape is placed immediately above the seeds sowed as described above. The reason why the mesh tape is used is that seeds of leaf vegetables located below the tape can grow through the tape after germination.

As a tape embodiment, a tape having a width of about 10 to 50 mm is used.
In addition to nylon, vinylon, polyethylene terephthalate, polypropylene, polyethylene, etc., the material of the tape uses biodegradable resins such as polylactic acid, polybutylene succinate, polycaprolactone, etc. to facilitate disposal after use. You can also. The shape of the tape mesh may be any shape such as a square (diamond) or hexagon, and an average diameter of about 3 to 10 mm.
It is preferable that the tape structure has a small elongation in the length direction in order to ensure good workability, while increasing the elongation in the width direction so as not to hinder crop growth.

The necessary conditions for the tape are that after sowing, the buds grow through the surface of the tape and can grow into a portion of the leaf stem that is used for food, while the root portion grows under the tape, and the tape is used for harvesting. When it is mechanically lifted, it can be lifted together with leaf vegetables as shown in FIG. 4, and can be separated from leaf vegetables after pulling.
Seeding is completed by covering all or part of the tape so that the seeds can emerge in the covering step.

  In order to grow and harvest leaf vegetables sowed by the above-described method, as shown in FIG. 4, one end of the tape 11 is fixed and wound up on a harvesting reel 15 mounted on a harvesting device (not shown). As a result, the tape 11 and the crop to be harvested are pulled up together, and the worker separates the crop and the tape 11 as appropriate.
