It is time to cultivate lettuce underground.

投稿日:2018年5月18日 更新日:

I am also an ordinary person, so I look up at the sky every day.
Then, I do not see how the basement is.
Apart from whether you can say that you are watching, underground depot and underground train will be all you can to enter underground.
Underground has permission so it can not be seen easily.
What is going on in the basement?
to introduce.
Speaking of Makuhari Shintoshin in Narashino City, Chiba Prefecture, I think that there is a stadium in Chiba Lotte Marines and an outlet is well known.
It is fairly known, but how many people do you know that it was a large under the road or a hollow.
How arriving from the outlet, towards Tokyo, so so, past the round one to the university.
There is a tunnel 3 kilometers to bake under this thick road.
But please be relieved. Under 10 meters underground, are you sure to consolidate? Because there is no collapse.
The dimensions of the underpass are 4 meters high, 6 meters wide and 3.1 kilometers long.
I think that it is quite long.
Well, what was it made for?
Makuhari Shintoshin is a landfill site. Urban development will be carried out by attracting companies to land landfilled,
As part of that, this long tunnel was maintained for infrastructure.
Looking at the map, it certainly crosses the middle of the city.
It was supposed to be bustling with office buildings built on both sides of this road.
But the economy fell down, yes, the bubble burst and the company did not come.
The underpass which was finished was left behind and the time passed.
It is now 20 years later, reuse started.
Even if we reuse it, I have no idea what kind of usage is available.
This tunnel is used for unexpected things.
How, raising lettuce.
High tech is amazing, is not it?
An alternative to the sun in the basement where the sun is not hit is LED.
LED seems to have low power consumption, long lifetime and only good things.
If you grow vegetables, I thought that soil is necessary, but there is no soil.
When I was in elementary school I remembered observing that roots and sprouts spread when placing water in a plastic container and placing a bulb on it.
It was hydroponic cultivation.
This water is also amazing. I have plenty of nutrients and keep giving for 24 hours.
I feel like growing fast.
There is something unique to the tunnel. It is the temperature. It may be called room temperature.
It’s constant around 18 degrees in the tunnel, is not it?
18 degrees is suitable for growing plants. It is a coincidence, it is perfect.
18 degrees is not the same in every tunnel, and the average annual temperature in that area seems to match the temperature in the tunnel.
Since room temperature is fixed by nature, it is not necessary to provide air-conditioning equipment.
If it is a vinyl house on the ground, heat will be applied if the temperature drops, if it gets too hot, it will be cools vinyl and put it in a cold place, it will cost labor and cost, so it is the difference between the clouds.
Although this facility, of course, is connected to the ground, when placing seedlings with eyes on the tray on a belt conveyor from the ground,
Automatically sent to the underground cultivation facility, it automatically fits in the breeding box, after 24 days it comes out automatically from the breeding box and is sent to the ground.
The 24th is the number of days it takes for lettuce to reach the size of the harvest.
Is not it amazing? When sending seedlings from the ground, they come back in size to eat.
Now, 2000 shares are finished on the 1st. It is said that it will be increased to 5000 shares per day in a year.
If this goes well, agriculture underground. It is interesting if it comes to a state like a tunnel under a street road.
Among them, “Production place: Chiba prefecture Makuhari underground” or stuck on the price tag of super vegetables.
