Chapter 9 Hydroponic Farm
Chapter 9 Hydroponic Farm
"The main body of the shelter is located ten meters underground."
“It connects the underground level to the surface through an inclined passage.”
“On the underground level, near the exit passage of the shelter, a disinfection room, a garage and a changing room can be placed to provide services for future entry and exit of the shelter.”
"It can also be equipped with a large lifting platform of about 20 square meters, which is large enough to carry vehicles."
"It is used to go from the first underground floor to the second underground floor, or even deeper underground."
On the laptop, Su Wu planned the space allocation inside the shelter bit by bit.
After first determining several necessary basic functional areas.
Facing the remaining 500 square meters of space on the first underground floor, Su Wu considered for more than half an hour before finally deciding to divide them into a 200 square meter rice planting area and a 300 square meter vegetable planting area.
In the end times of material scarcity.
Except electricity.
The most important thing is undoubtedly food.
Only after having food and ensuring basic survival can we talk about other things.
therefore.
Establishing a self-sufficient food and vegetable production area is the top priority.
The rice and vegetable planting areas built inside the shelter are naturally different from ordinary farmland outside.
It is based entirely on soilless cultivation, using artificial growth lights instead of sunlight to provide a suitable growth environment for rice and vegetables.
At the same time, in order to make full use of the valuable space inside the shelter.
The rice planting area will be divided into 4 upper and lower floors in the form of shelves. The vegetable planting area will be divided into 10 upper and lower floors. The actual planting area will be expanded to 800 square meters and 3000 square meters respectively.
“More than one acre of rice planting area.”
"Under the artificially created suitable environment, it is estimated that the growth period can be shortened to 4 months, and about 1600 kilograms of rice can be produced."
"Enough to supply the daily needs of at least ten people."
Su Wu's estimated yield is actually quite conservative, strictly speaking. Some high-yield hybrid rice can achieve 1.5 times or even twice the expected yield.
But this is not necessary.
The taste of high-yield hybrid rice is much worse than that of normal rice.
If he is able, Su Wu hopes to improve his quality of life as much as possible.
As for the vegetable planting area which covers a total of 3000 square meters, or nearly five acres.
Su Wu chose to plant fast-growing varieties such as lettuce, Chinese cabbage, spinach, and kale, and a small amount of common vegetables such as tomatoes and cucumbers.
The former focuses on efficiency and output, and is mainly used for trading with other shelters. The latter focuses on quality, and is reserved for Su Wu to improve his own food.
The various resources that Su Wu currently had in his hands were barely enough to build the framework of a personal shelter.
Want to live a better life and expand the size of the shelter.
It must be achieved through continuous external transactions.
This is also one of the meanings of the existence of vegetable growing areas.
The main vegetable varieties grown were determined.
Su Wu hesitated.
I simply added fruit planting plans such as strawberries, grapes, pineapples, etc.
These are also supplied to the shelter for daily use. Considering that people usually eat more fruits than vegetables, the area allocated for growing these fruits is quite large, more than 600 square meters.
Highlight a luxury and willfulness.
"That's it for now."
After completing all the planning for the underground level of the shelter, Su Wu stretched himself.
A rare feeling of satisfaction welled up in my heart.
His own shelter was finally starting to take shape.
Although there is only one layer for now.
But in an emergency, it is enough for him to survive in there for a long time.
Under the premise that the end of the world is approaching.
Nothing can make people feel happier and more at ease than this.
With planning, the subsequent construction will no longer be a problem.
The engineering team first made the frame of the large lifting platform, and then upgraded it through Su Wu's survival point and officially put it into use.
Then the construction team was divided into two.
Excavators and transport vehicles continued to dig the space on the second underground floor.
The engineering robot and two construction robots began to build a disinfection room, a dressing room, and a garage near the lift platform on the first underground floor. From time to time, they would go to the second underground floor to reinforce the newly excavated space.
Considering that the second underground floor is close to the rock layer, a simple excavator is inefficient. Relying on the fact that there are still plenty of survival points.
Su Wu also specially upgraded a professional gravel truck and joined the construction team.
After 24 hours of busy work.
The interior of the underground level of the shelter was built by three robots to look like a real thing. All the infrastructure such as pipelines, partitions, and vents were laid out.
There are only two soilless cultivation areas left, and construction has not yet begun.
5 month 31 day.
On the last day of May.
The underground level of the shelter has been officially completed.
After using a total of 5 survival points and adding a set of semi-automatic unmanned management equipment for two planting areas.
Su Wu named the underground floor the Hydroponic Farm.
Let it officially start running.
According to the planned categories, plant corresponding rice, vegetables and fruits.
Speaking of it.
It is necessary to mention one thing. Since we did not consider the issue of fruit planting in advance, many fruit seeds and seedlings were not prepared in advance. We could only go out to the market to buy them temporarily.
Fortunately, these things are basically available in seed stores.
Su Wu didn't spend much effort to trade them all for some canned food and grain.
There was no delay in the production of the hydroponic farm.
at the same time.
Still on this day.
Through the primary artificial intelligence Luo Tianyi, Su Wu searched the Internet for a piece of bad news that was temporarily unknown to the outside world.
Deep in the African Rift Valley, in a large tribal settlement, at around 155: in the morning, the ambient temperature broke the global historical extreme in a short period of time, reaching an ultra-high temperature of degrees.
Thousands of people in the entire tribe died of dehydration due to the extreme high temperature, and no one survived.
“The end of the world has come.”
Browsing the photos taken by the federal government's rescue team.
Su Wu vaguely realized that it might not be an isolated case, but the true beginning of the end of the world.
For a moment, I felt an involuntary shudder.
There was tension in his eyes, as well as a hint of uneasiness about the future.
No matter how well prepared we are, the fragile human body is ultimately as small as dust in the face of a disaster that can change the world.
6 month 1 day.
The disaster spread faster than expected.
This morning.
The second extreme high temperature spot appeared over Antarctica.
Countless glaciers are melting and evaporating at a speed visible to the naked eye.
Above the ocean, hurricanes roared and heavy rains poured down.
A few hours later.
The closest coastal city to Antarctica.
The city was engulfed by the sudden tsunami, and more than 20 people were missing.
And it is thousands of miles away.
In the coastal cities of Dongzhou, at the same time as the tsunami appeared, a long-lasting alarm was sounded.
All TV stations began to repeatedly broadcast the emergency announcement issued by the federal government.
Residents living in these coastal cities and ports are required to immediately evacuate to inland highlands for refuge.
But an evacuation operation involving millions, or even tens of millions of people.
It is simply impossible to achieve in a short period of time.
The tenth hour after the alarm was sounded.
The first group of evacuees had just left the coastal plains and were heading towards the inland highlands.
More people are still stranded in coastal cities.
Racing with death.
Waiting for the decision of fate.
