Description

[Detailed description of the invention] J Kari Lai Xianwang The present invention relates to a plant cultivation device.

Green plants and certain bacteria have the ability to synthesize organic carbon compounds from carbon dioxide gas and water using the energy of light.
This action is called photosynthesis. The photosynthetic reaction is divided into two stages: splitting the water supply and converting carbon dioxide into organic carbon compounds (carbon dioxide fixation). The former reaction is a step in which oxygen and strongly reducing hydrogen are produced from water using the energy of light catalyzed by chlorophyll proteins, and a portion of the strongly reducing hydrogen generated here is used for the reduction necessary for the next carbonic acid fixation reaction. used in the production of substances. The latter stage of carbonic acid fixation is an enzymatic reaction that does not require light, so it is called the dark reaction of photosynthesis, whereas the former is called the light reaction.

As mentioned above, photosynthesis consists of light reactions and dark reactions, and plants grow by transferring the nutrients produced by photosynthesis to their trunks, fruits, etc., but this transfer occurs only when light is not provided. , is more effective when there is oxygen or at a lower temperature. In other words, in order to effectively grow plants, it is necessary to carry out a photosynthetic reaction and transfer the nutrients produced by the photosynthetic reaction, but in order to carry out photosynthesis effectively,
It is preferable that the brightness and darkness of the supplied light be repeated at predetermined time intervals. In other words, plants require a light period corresponding to day and night, and this period is usually about 2 hours, and the light period is the period during which photosynthesis takes place.
The light period is the period during which plants transfer nutrients from leaves to stems to fruits.During the light period, plants require carbon dioxide for photosynthetic reactions, and during the light period, they require oxygen for respiration. Therefore, it is advisable to supply carbon dioxide at a relatively high temperature and appropriate humidity during the light period, and to supply relatively low temperature oxygen during the sunny period.

However, under the conditions described above, it is difficult to establish a coexisting relationship with humans.

An object of the present invention is to solve the above-mentioned drawbacks and establish a coexistence relationship with humans, and to further promote the growth of plants by providing plants with sufficient carbon dioxide gas and effective An object of the present invention is to provide a plant cultivation device capable of supplying light.

The configuration of the present invention will be described below based on examples.

FIG. 1 is a schematic vertical sectional view for explaining one embodiment of the present invention, and in the figure, 10 indicates a plant cultivation room, in which:
A packet conveyor 20 for picking up plant cultivation packets 211 to 21rl is accommodated. As shown in FIG. 2, the bucket conveyor 20 consists of two endless annular belts or chains 23 circulating between pulleys 22, and plant cultivation packets 211 to 21n attached between the belts or chains 23. The packets 211 to 2In are connected by rotating shafts 24 protruding from both ends so that they hang down due to gravity and remain horizontal regardless of the direction of the belt or chain 23. Therefore, packets 211-2
As the belt or chain 23 vertically circulates, In circulates up and down without causing any physical change to the contents of the packets 211 to 21n. Note that 30 indicates plants cultivated within the packets 211 to 21n.

Reference numeral 11 denotes a shielding plate that divides the plant cultivation room 10 into two rooms A and B, and sunlight collected by a sunlight collecting device (not shown) installed outdoors is transmitted to room A. An optical fiber 40 is provided, and sunlight is emitted from a light leakage portion provided in the optical fiber. Room A, where the optical fiber 40 is installed, is provided with a supply port 12 and an exhaust port 13 for air at an appropriate temperature and humidity containing high concentration of carbon dioxide gas, and room B, where the optical fiber 40 is not installed, is provided with a supply port 12 and an exhaust port 13 for air containing a high concentration of carbon dioxide. A supply port I4 and a discharge port 15 for relatively low temperature air are provided.

The shielding plate 11 includes the plant cultivation packets 211 to
A notch 16 is provided so as not to impede the vertical circulation movement of 21n. 50 is a water nozzle. Further, 60 is an artificial light source, which is used when sunlight is not available.

By operating the packet conveyor 20, the plant cultivation packets 211 to 21n alternately circulate between the bright room A and the dark room B of the plant cultivation room 10 at predetermined time intervals. The plants cultivated in the packets 211 to 21n receive water from the watering nozzle 50 during the light period while moving through the bright room A, and are supplied with air at an appropriate temperature and appropriate humidity containing light energy and high concentration of carbon dioxide gas. and perform photosynthesis. Then, during the next light period when moving through the dark chamber B, relatively low temperature air containing a lot of oxygen is supplied, and nutrients produced by photosynthesis are transferred. That is, photosynthesis and transfer of nutrients generated by the photosynthesis are performed discontinuously at predetermined time intervals. In addition, since the shielding plate 11 in the plant cultivation room 10 is provided with a notch 16 for the packets 211 to 21n to pass through, the air in the A room and the B room mixes to some extent. However, the temperature of the air in each room is different, so it is not uniform.

FIG. 3 is a schematic longitudinal sectional view of another embodiment of the present invention,
211 for plant cultivation using a packet conveyor 20
~21n are configured to circulate mainly in the horizontal direction within the plant cultivation room 1o. Note that the same parts as those in the embodiment shown in FIG.

■ As described above, according to the present invention, the packet in which the plants are grown is alternately circulated between the bright room and the dark room at predetermined time intervals, allowing the plants to effectively carry out photosynthesis and transfer of nutrients. In addition, it is possible to efficiently cultivate plants by making the most effective use of space and sunlight while establishing a coexisting relationship with humans. Furthermore, since sunlight can be supplied even if the plant cultivation device of the present invention is installed in a shaded place, a basement, etc., there are few restrictions on the installation location, and it is particularly suitable for most places.
