Description

[Detailed Description of the Invention] The present invention provides plant cultivation equipment and objects that can supply sufficient nutrients, light and carbon dioxide necessary for photosynthesis to plants in coexistence with humans. .

In order to effectively grow other things, appropriate nutrients, light, carbon dioxide, heat, temperature, humidity, etc. are required, but it is difficult to satisfy all of them, and it is difficult to have a coexisting relationship with humans. It will not be established. On the other hand, carbon dioxide gas, fM degrees, heat, etc. are harmful or undesirable to humans. ′ □ The present invention was made in view of the above-mentioned circumstances;
In particular, we are trying to put together a device for cultivating tsukudoku that can most effectively grow yuzu fruit while establishing a coexistence relationship with humans. □、Place...The figure is...! The invention includes apparatus for cultivating yams and plants -4, , , q; , 4.

Overall configuration for compiling without explanation': Figure. In the figure, ■ is the other product @ equipment by Kihatsu □ Tomo □ 3. The tub q, cultivation device 1 is composed of a dark room section 10 in which the roots of the plant P are bathed, and a closed room section 20 in which the stems and leaves of the plant are accommodated. A porous hole ft' 11 is provided for supplying nutrients, oxygen, etc. necessary for the growth of the plant P, and the culture solution, air, etc. supplied to the porous pipe 1↓ through the inflow pipe 12 are passed through the porous tube 11. rii'1. ] is released into the dark room through the holes, supplying the necessary nutrients and oxygen to the plant P.

After supplying nutrients and oxygen to the plants P in a rib-like manner, the waste liquid is discharged through the outflow pipe 18, and once again supplied with nutrients and air, it is circulated and supplied through the inflow pipe 12, and strained air is discharged through the exhaust pipe 14. be done. On the other hand, sealed room 2
A large number of light sources necessary for causing the plant P to carry out photosynthesis reaction 1ia are provided in the 0! - Inflow pipe 21 for circulating 1#, acid gas, heated humidified air, etc. into the J room. An outflow pipe 22 and the like are provided, and the environment inside the sealed chamber 20 is adjusted according to the characteristics of the plants to be cultivated. Brewing gas m degree 8%, """ m, every □'
1'□This is maintained at A-28・C. In addition, light source L□
Finally, it generates light of the wavelength necessary for light synthesis.
For example, xenlumba is an example of this, as heat is not required to carry out the photosynthetic reaction.
A cool light source that does not generate heat is preferable. For this cool light source, for example, as shown in the figure, two optical substances with a refractive index larger than that of the optical fiber are attached to the surface of the optical fiber 28, and the light is propagated within the optical fiber 28. It is preferable to emit the incoming light through the transparent material 24. Note that 25 is a light guide cable.
Reference numeral 26 denotes an optical coupling that connects the optical conductor cable 25 and the optical fiber 28, and the unillustrated end 11S of the optical conductor cable 25 focuses sunlight or artificial light such as a xenon lamp. Is it a bad lens?
k l,t, and the light focused by the lens is introduced into the light guide cable 25, and the light transmitted through the light guide cable 25 is transmitted to the optical fiber 28, and as described above, the light is Light propagated through optical fiber 23 is emitted through transparent material 24 . Also,,,
The sound container 20 is made of a transparent material so that the inside of the sealed chamber can be visually observed. Either enter the sealed room and harvest after exchanging the humid air with normal clean air, or 1. It is advisable to provide a large number of windows (11) that can be closed freely on the peripheral wall of the honey-closing vessel 20, and to harvest the honey by inserting a hand through the windows.

In addition, plants are required to perform photosynthesis while their stomata are closed, and once their stomata are closed, they do not need light and can sit.
Supply y4 only while the stomata are open, cut off the light supply while the :λ pores are closed, and at the same time block external light by covering the entire plant cultivation device. The HI transfers the nine synthetic substances towards the fruit during this darkness, in other words it blocks the light for the time required for the photosynthetic substances to be transferred towards the fruit. Then, when the photosynthetic substances are transferred to the fruit, the stomata open, providing nine volumes of open stomata. In this way, it is possible to monitor the opening of the stomata and control the supply and blocking of light, but in order to use light more effectively, it is necessary to It is best to prepare multiple cultivation devices and alternately switch the light supply.

However, controlling the light supply by actually monitoring the opening and closing of the stomata requires complicated and expensive equipment, so the switching period must be determined in advance and the switching period can be adjusted according to the time schedule. Surt is good as it is.

As is clear from the above explanation, according to Akira Honkan, person 1
Torimono forced cultivation can be carried out effectively and effectively while maintaining a coexisting relationship with nJ. −
