Description of the Related Art In recent years, in agriculture, seedling production and cultivation are often performed in different places, and seedlings are now specialized in raising seedlings. What is required of the nursery industry is to produce economical, efficient and healthy seedlings. In particular, as the term “seedling half cropping” implies, the quality of seedlings greatly affects the growth of subsequent crops. In other words, seedlings with short internodes and a solid base are well-grown after planting, and since they firmly support the aerial parts, they are well-received and are desired as healthy seedlings that are less susceptible to diseases.

4−121117、特開平5−115219号公報)。In order to perform plant cultivation efficiently and stably irrespective of the weather, attempts have been made to use mechanized equipment and facility cultivation in which the growth environment is artificially controlled using artificial light sources.
Some have been put to practical use. As artificial light sources, high-pressure sodium lamps, metal halide lamps, fluorescent lamps, incandescent lamps and the like are used. It has also been proposed to use a light emitting diode or a semiconductor laser as a light source (Japanese Patent Application Laid-Open Nos. 4-121117 and 5-115219).

−149729号)。[0004] Similar light sources are used for light irradiation at the seedling raising stage, but these are intended to supplement light energy for photosynthesis when solar radiation is insufficient.
The light irradiation spectrum is mainly composed of red, blue or green light. In facility cultivation using artificial light sources, research has been conducted on the relationship between the growth of plants and the wavelength of light to be irradiated, and red light is mainly used for photosynthesis, blue light is mainly phototropic, and far red light is used for It is mainly involved in flower bud formation. Further, it is known that far-red light has a germination inhibitory action and a stem elongation action on certain plants. Thus, the present inventors first supplement the far-red light, which is said to be not used for photosynthesis, with light for a specific period at the time of raising a seedling, thereby preventing growth and suppressing the growth of the hypocotyl to grow a healthy seedling. Proposed a method (Japanese Unexamined Patent Publication No.
No. 149729).

形苗の栽培方法に存する。Means for Solving the Problems The present inventors are not effective in photosynthesis when growing cell-molded seedlings in a substantially closed system, but rather have the effect of extending stems and petioles and the effect of suppressing germination. By irradiating far-red light, which is said to be cultivated during most of the nursery period, cultivation is prevented,
The present inventor has found that a healthy seedling in which the elongation of the stem (hypocotyl) is suppressed can be efficiently produced, and the present invention has been achieved. That is, the gist of the present invention is a flowering plant of the seedling raising stage, a cell-shaped seedling of fruit and vegetables,
The present invention is directed to a method for cultivating cell-formed seedlings, which comprises irradiating far-red light having a peak wavelength only at 670 to 750 nm in a substantially closed system and cultivating the cells.

The seedlings are usually sowed by a machine in a series of small pots (cell forming trays) called cells, which are formed of plastic or the like, and germinated and raised in the cells, and then shipped as they are. In the method of the present invention, the cultivation method of the plant is not particularly limited, for example, sowing the seeds in a cell forming tray filled with a medium, immediately after sowing or immediately after germination, for example, in a substantially closed system such as a nursery box 670-75
The cultivation is performed by irradiating far-red light having a peak wavelength only at 0 nm, preferably 670 to 700 nm. During cultivation, the amount of light, day length, temperature, humidity, and in some cases, the concentration of carbon dioxide are adjusted. Bottom watering is preferred for watering and liquid fertilization. Cultivation by irradiating the wavelength can be performed during most of the growing period of the seedling. The photon flux density for irradiation is
10 μmol / m 2 · s or more is required in the cultivation surface state.

れる。[0008] The light source of such light is not particularly limited as long as it can emit desired far-red light, and optical semiconductors, in particular, light emitting diodes (LEDs), semiconductor lasers, fluorescent lamps and the like can be used. Is mentioned. In particular, a light emitting diode has a sharp emission spectrum, easily obtains light having a specific peak wavelength, and can irradiate only light having a wavelength useful for raising seedlings. Also, since it hardly irradiates heat rays,
Since the irradiation can be performed in close proximity to the plant, the efficiency of light utilization is excellent, and the cultivation space can be reduced, so that the temperature in the nursery box can be easily controlled, and the cost required for cooling can be reduced. It is preferable because it has advantages such as the following. The seeded cell forming tray is almost in a closed cultivation device,
The emission wavelength is 670-750 nm, preferably 670-7
Cultivated by irradiating artificial light having a peak wavelength at 00 nm.

できる。Since the present invention is implemented in a substantially closed system, it is possible to control the cultivation environment such as temperature and humidity at a high level. Therefore, unlike the seedling raising usually performed in a greenhouse, it can be expected that the seedling raising period fluctuates due to the season and the weather, and that the seedling is released from various environmental control treatments for controlling the growth rate. Further, since the environment in the system is easily adjusted, it is easy to set the optimum conditions (light, temperature, humidity, carbon dioxide concentration, etc.) of the plant, and to promote the growth rate.
