DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a plant cultivation method for cultivating plants on a large scale.

[0002]

2. Description of the Related Art In recent years, attempts have been made to cultivate plants in a plant factory by controlling illuminance, lighting time, temperature, humidity and the like using a large-scale plant cultivation apparatus.

[0003]

THE INVENTION The problem to be solved by a conventional plant cultivation method, so had to and at the same time during the day cultivation control and nighttime cultivation control the entire cultivation apparatus of a vast area, the need for electric facility construction of large capacity, capital investment There will be very large, also high noon between temperature and must be repeated by controlling the low night temperatures and during the night the temperature from the state in which case, the temperature was increased by much trouble expensive heat sources to switch from daytime temperature to night temperature The temperature must be lowered by an air conditioner, and when switching from a low night temperature to a daytime temperature by cooling with an air conditioner, the inside of the cultivation equipment that is cooled to a low temperature reaches a high daytime temperature. since must be raised Kasami power rates, eventually, a long time is required for temperature conversion with becomes cost high, production efficiency is low.

SUMMARY OF THE INVENTION The present invention strikes a foster artificially plants shielding and heat shielding can and the cultivation room in order to the control <br/> control and temperature control of the irradiation time, the cultivation Block the room
Divided into light and heat shieldable sections , and adjacent sections
One is a lighting section with a high daytime temperature, and the other is a lighting section
With low night temperature and none of those lighting and unlit compartments
When switching the temperature between day and night, the high temperature section is turned on and the low temperature section is turned off.
Circulating air with each other to eliminate the temperature difference or
After the temperature difference is reduced, the compartment that converts to night temperature is cold.
Heat the sections that convert to daytime temperatures to the appropriate temperature
The above-mentioned problem was solved by controlling to.

[0005]

With further described in detail with examples EXAMPLES The present invention, 1 is a cultivation apparatus which structure capable heating shielding and shielding the ceiling 2 and the wall 3, in the middle of the width direction, the light-shielding property and shielding provided partition walls 4 having thermal resistance is formed in the partition 5 and 6 independent both sides thereof, circulation fan 7 in the said partition Setsukabe 4, for discharging by suction the one compartment 5 of the air to the other compartment 6
When attaching a circulation fan 8 for exhausting into one compartment 5 by sucking air in the other compartment 6, to their compartment 5,6, each culture tank for hydroponics, or cultivation racks 10 ..
In addition, appropriate cultivation equipment is to be arranged,
A number of lamps 12 are mounted on each upper part of the cultivation apparatus .

[0006] In a separate control room 15, a control device is provided.
If Yes set up a location, the control equipment is performing various controls, the time the lamp 12 is set by a timer as one was lit one compartment 5 while controlling the illumination, the other Section 6 is turned off, and one heat pump 17 is operated for heating, and the heat exchanger 18 in one section 5 is heated to, for example, 28 ° C., the other heat pump 17 is operated for cooling, and the other heat pump 17 is cooled. The heat is cooled to, for example, 23 ° C. by the heat exchanger 18 in the section 6, and the sections 5 and 6 are cooled.
The temperature of the heat pump 17 is controlled based on the detection value of the temperature sensor disposed in the room to maintain the room at the appropriate temperature. 1

Next, when the day and night of the two sections 5 and 6 are reversed after a set time, the lighting of one section 5 is turned off and the other section 6 is turned on. Simultaneously, the circulation fans 7 and 8 are driven, and one circulation fan 7 sucks one section 5 and discharges it to the other section 6, and the other circulation fan 8 sucks the other section 6 and draws one section 5. To be discharged. If this circulation is continued, the low-temperature air and the high-temperature air are mixed and the temperature difference is rapidly reduced, so that when the temperature difference between the two compartments 5 and 6 becomes small or substantially equal, the circulation fan 7 to stop the 8, the one compartment 5 is cooled, after each day or become night temperatures other compartment 6 and warmed to thereafter thermostatic control.

[0008]

According to the present invention, control of irradiation time , temperature control,
Hit the growing population to plant <br/> thereof in light shielding and heat shielding can and the cultivation room in order to a said cultivation room shielding and possible thermal barrier
Is divided into a plurality compartment and, one lit compartment of Aitonaru compartment
Is a high daytime temperature, and the other is a low-light nighttime temperature in an unlit section.
Switching between day and night temperatures for these lit and unlit sections
When turning on, the air in the hot hot compartment and the cold cold compartment
To eliminate the temperature difference or reduce the temperature difference
After that, the compartment that converts to night temperature cools down,
The sections that are converted to the temperature are heated and controlled to the appropriate temperature , respectively.
The air of the image is mixed by the circulation fans 7 and 8
It can be used effectively and cooled as before.
Room that is suddenly heated to a high temperature
There is no need to suddenly cool the inside, eliminating waste
Heat efficiency and temperature conversion.
Can be shortened.

The power distribution equipment required for the cultivation apparatus or
It is possible to substantially reduce the capacity of power transmission equipment etc. by half.
As a result, the cost of electric construction work can be greatly reduced.
