がある。2. Description of the Related Art Conventionally, seeds are generally sown without being coated. However, in order to protect seeds from damage by animals and to perform pretreatments such as sterilization and germination promotion treatment before sowing, There are coated seeds that cover the seeds. Conventionally coated seeds have a mixture of clay, fine sand or sugar attached to the surface of the seed, and a relatively hard coating with a fungicide, oxygen generator, etc. added to the coating, or the seed is hydrated. There is a soft coating which is coated with a gel or gelatinous substance which swells as a result.

きる。[0003] In such a conventional coating technique, there has been no example of coating a seed using an aqueous gel that cures only the surface layer. However, the present applicant has proposed a method of coating a gel film formed in a spherical film shape. Seal the seeds and air inside,
A method for producing seeds coated with a gel film that hardens only the surface of the gel film and protects the seeds and facilitates germination was proposed (see Japanese Patent Application No. 4-141006). The gel membrane cover can coat not only seeds but also seed analogs (tissue cultures such as adventitious embryos).

上に被さって苗の成育を妨げる。The seeds and seed analogues coated with the gel film (seeds coated with the gel film) have a substantially spherical surface and a substantially uniform size. Although there is an advantage that it is easy to sow in soil, the following problems occur when sowing it in a hydroponic culture medium A made of a water-absorbing material such as urethane. (1) As shown in FIGS. 5 and 6, when a seed B is provided on the surface of the culture medium A for hydroponics, the culture medium A for hydroponics is used.
The gel film C has no power to hold the gel film, and the gel film C is put on the germinated seedling to hinder the growth of the seedling.

When the seed D covered with the gel film C is inserted into the inside, and the gel film C is to be held by the cut E, the gel film C having a large diameter must be inserted into the cut E, so that seeding is difficult. become. An object of the present invention is to solve such a problem, and to provide a hydroponic culture medium that facilitates sowing of seeds covered with a gel membrane and has a gel membrane holding power.

く、ゲル膜によって成育を阻害されることはない。The seeding operation on the hydroponic culture medium configured as described above may be a simple operation of pushing the seeds covered with the gel film into the seeding holes on the upper surface of the hydroponic culture medium. When the seeds covered with the gel film are pushed in, the seeding hole expands elastically and supports the gel film with a small locking force. Since the gel membrane is lightly locked in the seeding hole, when the seedlings germinated from the seeds project from the surface of the hydroponic culture medium via the seeding hole, they protrude with the gel membrane covered. The growth is not inhibited by the gel membrane.

Occurs. When the seedlings germinated from the seeds protrude from the surface of the culture medium for hydroponics via the cut for germination, the gel film is left in the insertion hole, so it does not protrude with the gel film covered. The growth is not inhibited by the gel membrane.
