Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a plant cultivation device for moving and growing plants under an artificial light source.

[Conventional technology]

Patent No. 52-102128 is a method for reducing lighting power costs, which account for a large proportion of energy costs in conventional methods of cultivating plants under artificial light sources.

The methods disclosed in Japanese Patent No. 55-24000 and Japanese Utility Model Application No. 57-446863 were implemented.

FIG. 6 is a sectional view showing a conventional plant cultivation apparatus disclosed in, for example, Japanese Patent No. 55-24000.

In the figure, 1 is a moving bed of plants 1, 2B is a moving bed of plants, 2b*2c is a plant.

3 is an artificial light source for growing plants 2a*2b+2c.

Next, the operation will be explained. Plants 2a, 2b, 2c
By irradiating the artificial light source 3 with Eliminate light, the plants 2a are grown on the moving plant bed 1, such as Plant 2a+ Plant 2
b, Plant 2c+ grows and becomes larger. plant 2a+2
As b+2c increases, the moving distance of the moving bed 1 increases. Then, the cultivation intervals of plants 2a, 2b e 2c become larger. With the above operations, plant 2a +
2b + 2c is cultivated in a densely planted manner in order to make the amount of artificial light proportional to the growth of the plant during the growth process, and the light from 1 artificial light source 3 is effectively irradiated to the plants.

Reduce lighting power.

[Problem that the invention seeks to solve]

Since the conventional plant cultivation device is configured as 0 or more, the cultivation interval of plants must be expanded in proportion to the growth of the plants. However, the mechanism for changing the cultivation interval of plants is complicated and expensive.

This invention was made in order to solve the above-mentioned difficult problems.It is possible to eliminate the opportunity to change the cultivation interval of plants, and to obtain a plant cultivation device that can reduce the lighting power. The purpose is to The latter t'i, especially when growing plants under an environment using an artificial light source, is a great advantage in reducing energy costs, which is a major economic problem, and shows the importance of the present invention.

[Means for Solving the Problems] The plant cultivation device according to the present invention changes the density of the light source as the plant grows, and maintains the illuminance at a level suitable for the plant growth throughout the plant growth process. be.

[Effect] As plants grow and become larger, the amount of light required for growth increases. As a result, when plants are grown under the same light source arrangement and at a constant cultivation density, the illuminance received by the plants, which are irradiated objects, decreases. Increasing the density of the light source prevents a decrease in illuminance. By moving the plants to the required JA environment according to their growth level, the growth environment of the plants is maintained, and problems such as a decrease in growth rate do not occur. By arranging light sources suitable for plant growth, there is no wastage of light sources and efficient lighting energy consumption is ensured.

[Embodiments of the invention]

The following is an example of this invention. In Figures 1 and 2, 1 is a moving bed of plants e 2a+2b+2cVi
Plants grown on moving plant beds i, 3i! This is an artificial light source for growing the plants 2a + 2b + 2c, and is installed at approximately the same height from the movable bed 1 so that the density of the plants increases gradually.

5. FIG. 2 shows the state of FIG. 1 after a certain period of time has elapsed.

Next, the operation will be explained. Plant 2a+ 2b+ 2c
When irradiated with artificial light source 3 for growing f, plants 2a+
2b 12c grows and becomes larger over time on the moving bed i. As the plant 2a grows, the density of the light source 3 it requires increases. , plants 2a, 2b, 2c
In FIG. 1, the number of 30 artificial light sources suitable for the growth of plant 2a is, for example, 3 for the size of plant 2a, 6 for the size of plant 2b, and 9 for the size of plant 2c. Plant 2a in FIG. 1 moves a certain distance after a certain period of time and is at the position of plant 2a in FIG. During this time, the plant 2a grows from the size of the plant 2a in FIG. 2 to the size of the plant 2b in FIG. 1. plant 2a
When the size of the plant is as shown in Fig. 122, it is irradiated with 6 artificial light sources suitable for its growth. When the moving bed 1 moves a certain distance after the plant 2a has passed a certain period of time, the plant 2a grows by a certain amount, and the density of the artificial light source 3 suitable for the growth of the plant 2a increases by a certain amount. By increasing the density of the artificial light source 3 from the inlet to the outlet of the plant in the plant cultivation device, it is possible to always provide illuminance suitable for the growth of the Eri plant.

Here, the density of the artificial light source 3 suitable for the growth of plants 2a, 2b, 2c was explained based on the size of all plants 2a, 2b, 2c, but depending on the type of plants 2a + 2b + 2c, the weight of plants 2a + 2b, 2c, The height may be correlated to one volume.

Further, the moving bed 1 may be moved continuously or intermittently.

In the above embodiment, the arrangement of the artificial light source 3 is
+ 2b + 2c were arranged as an artificial light source group for each plant, but as shown in Fig.
It is also possible to arrange 6 dispersed plants without corresponding to the a+2b+2c strains.

Further, in the above example, plants 2a # 2b and 2c were
Plant group A, as shown in Figure 4, was moved plant by plant.

They may be moved as B and C.

Alternatively, as shown in FIG. 5, one artificial light source group may be arranged by dividing the plants 2a, 2b+2c into a plurality of growth periods, E and F.

〔Effect of the invention〕

One of the above two points is that according to the present invention, the amount of movement of plants is always kept constant, so moving beds can be made at low cost. Since the artificial light sources are arranged according to the growth of the plants, there is no waste of artificial light sources and energy costs are reduced.

Moreover, there is an effect that efficient plant growth can be obtained.
