January 17, 1939, AD 2780, Tiangong-1 space station group, "Pan Taoyuan" space farm.
With the increase of space buildings, Tiangong-1 is now not just a space station, but a group of space stations.
Because the name here is Tiangong-1, some good people have given different nicknames to various functional modules. as a distinction.
For example: the main body of the space station, which is mainly composed of various laboratories, is called "Lingxiao Hall", and there are the following functional buildings around it: "Nantianmen" is a spacecraft parking center that serves as a skytrain and spacecraft entering and exiting the station; The personnel living and rest area is called "Qionghua" "Palace"; the part that serves as a space smelting plant is called "Dousita Palace"; there is also "Tongming Palace" as a silicon wafer production base; "Baoguang Palace" as an optical fiber production base, etc., and is called "Pan Taoyuan" "It is a space station that serves as a space farm.
Later, the nicknames of these places became louder and louder, and even the officials recognized them, so they officially upgraded these nicknames and used them as the code names of these functional modules.
In fact, "space farm" is not a formal name, it is just a general name.
Its scientific name is "controlled ecological life support system", which relies on the reproduction of green plants, vegetables, algae, etc. in space to provide the food, oxygen and water needed by astronauts on the spot.
The supply of the most basic materials such as spacecraft is one of the key technologies and problems in realizing long-term manned interstellar travel and immigration in the future.
Space is the future home of mankind, and to live in space for a long time, it is not enough to rely solely on the support of the earth.
Space must be turned into an oasis, and space farms must be established to make at least part of the food self-sufficient.
In China's sky plan, in the near future, manned landings will be on the moon, Mars and even other planets, which will require a large amount of supplies.
If we only rely on ground supplies, a huge supply team will be needed to travel back and forth.
Transportation is not only expensive, but also technically difficult to guarantee.
Space farms can use the photosynthesis and transpiration of crops, vegetables and other higher plants to produce food, oxygen and water, and use the degradation of specialized microorganisms to decompose and reuse biodegradable waste, which can achieve a closed cycle of materials in the system.
In this way, only a small amount of stored food and water can meet the daily needs of the crew, providing a good solution to the supply problem of long-term manned spaceflight.
In the history of original time and space, since the advent of artificial satellites, scientists have begun experiments in plant cultivation in space.
The United States, Russia and other countries have experimented with planting and cultivating more than 100 kinds of plants on the space station, including peas, wheat, corn, rice, onions, orchids, and tulips, to study the effects of various factors during spaceflight on plant growth.
During their long-term lives on the Salyut and Mir space stations, Soviet astronauts sowed wheat, onions, orchids and other plants.
The results showed that the plants grew faster and matured earlier than on earth.
The United States has also conducted experiments on planting pine trees, oats, mung beans and other plants in space laboratories and space shuttles.
It was found that not only was the growth of these plants not affected under weightless conditions, but compared with similar crops grown on Earth, their protein and other nutrients were lower than those of similar crops grown on Earth.
Material content is generally higher.
This shows that growing crops in space is feasible and can increase yields.
At the same time, the United States and Russia also conducted animal breeding experiments in space.
The results proved that animals such as fruit flies, spiders, fish, etc. can grow and breed freely like on the ground.
In space farms, plants can grow in sand or foam, or they can be suspended in the air.
As long as the plants have water, nutrients and support, they can survive, develop and grow in the weightless conditions of space.
Moreover, the weather is favorable and the yields are high in every season.
Cattle, sheep, chickens, fish and other animals on the farm can also grow normally, providing space residents with fresh vegetables, fruits and abundant meat, eggs, milk and other foods.
By the 22nd century, humans had already spread their footprints across the Milky Way, and had rich experience in raising and cultivating animals and plants in space.
In the 23rd century before Wen Desi traveled through time, people further discovered that if humans were in an environment without other living things for a long time, they would easily develop depression.
This special mental illness is called "depression due to lack of biological environment." ".
Therefore, international organizations and governments of various countries at that time mandated that any place where people would stay for a long time outside the earth must be equipped with a small biological environment and a small ecological circle to raise various animals and plant various plants.
This is why there is a zoo and a botanical garden at the base of Wen Desi's office building.
China Aerospace in this plane, thanks to the guidance of Wen Desi, a man from the future, has avoided many detours, so it formulated a plan for space breeding of animals and plants from the beginning.
On the one hand, it is to create a small ecological circle to provide food for astronauts, produce food, oxygen and water, and decompose and reuse biodegradable waste.
On the other hand, it is also to ensure the mental health of astronauts and avoid "depression due to lack of biological environment."
Of course, there is another very important reason, that is, China has always prided itself on being a “big foodie empire”.
Even in space, how can we live up to this title if we don't have abundant food?
Even if we don't have the conditions, it's not impossible to live a hard life, but if there are conditions, the astronauts are still allowed to eat "toothpaste" every day.
It’s not Chinese style, nor is it Mr.
Wen’s style.
This kind of "toothpaste" specially designed for astronauts sounds very high-end, but it is the most basic space convenience food.
It is indeed rich in nutrients and has sufficient calories, which can fully meet the needs of human survival, but the taste and texture are Well, let’s forget it, I’m still in tears.
Friends who are interested can try it by making it by themselves.

It is very simple, just mix rice noodles or flour with minced fish, minced meat, vegetable puree, fruit puree, cooking oil and seasonings, and boil it into a paste.
It's almost like this.
If you find it too troublesome, you can also buy it online.
You may feel fresh after eating it once or twice.
If you eat it for a few more days, you will definitely feel like vomiting after seeing it.
"Pan Taoyuan" is connected to the residential area "Qionghua Palace", which is also to facilitate the supply of food, water and oxygen to the residential area, and also to facilitate astronauts to visit "Pan Tao Garden".
The structure of the entire "Peach Garden" is like a huge wheel composed of four concentric circles.
The "Peach Garden" is constantly rotating clockwise, causing it to generate artificial gravity.
The "axle" is divided into two layers: the inner and outer layers.
The inner layer is a gravity-free area, which is fixed and serves as a power area and a passage area.
The outer layer is connected to the outer rim through eight "spokes" and will rotate, so this is a microgravity area with a gravity of 0.05g, which is five percent of gravity.
Then the four layers of rims correspond to different gravity because of different linear speeds.
The diameter of the outermost layer is 300 meters.
It rotates at a linear speed of nearly 8 meters per second and rotates once in about 120 seconds, which is 0.8 Double the force.
Then it decreases in sequence, and the innermost circle is 0.2 times the gravity.
Of course, this gravity can also be adjusted.
You can easily change the gravity by just adjusting the rotation speed.
The "Peach Garden" is divided into six areas based on the different gravity zones formed by four concentric circles and axles, and each area cultivates different animals and plants.
"Pan Taoyuan" is said to be a farm, but it is actually a large biological laboratory.
It is mainly used to study the growth and development of different organisms under different gravity conditions, and what will happen.
Since the nickname of the space farm is "Peach Garden", peaches are naturally indispensable in it.
However, we can only eat a small part now, because there are only 20 mature peach trees that can bear fruit, and the other peach trees are still saplings in different stages.
It takes three years for a peach tree to bear fruit.
Even if it grows faster in space, you still have to wait until at least next year to eat the second batch of peaches from the peach tree.
Some people may ask, why not just send the trees that can bear fruit directly up?
Yes, it is definitely no problem to send them up.
Although the crane's transportation capacity is sufficient, adult peach trees take up too much space.
Now the crane's transportation capacity is extremely tight. 20 trees is already pretty good.
How can I have so much free space to send you a large number of adult peach trees?
Have you ever seen the Spring Festival travel rush?
That's right, Tongtianqiao is like the Spring Festival travel rush now.
Every train is full.
The staff just arranges the departures.
They are so worried that they can't wait to use one cubic meter as several cubic meters.
How much space does a mature peach tree take up?
So except for the 20 mature peach trees initially sent up, the others are seedlings and even seeds at different stages.
However, the first batch of peach trees has now produced fruits.
In addition to keeping half of this batch of space peaches for the Tiangong-1 staff to eat, the other half was given as gifts to be sent back to Earth.
These peach trees are originally selected and improved varieties.
Under the conditions of microgravity, their peaches have grown larger.
The largest one is as big as a small watermelon.
After weighing it, it weighs more than 5 kilograms and a little over ten kilograms. peach This giant peach and several other smaller peaches were given to Mr.
Wen by the space center.
Mr.
Wen summoned all the central high-level officials and relevant major scientific researchers to share these super peaches together.

After everyone ate it, they all praised it and said that it was much more delicious than the ones on earth.
They were indeed the flat peaches in heaven.
Apart from the psychological factor of eating something strange, the quality of this peach itself is indeed very good.
After testing, it was found that the sugar content and nutritional content of this peach are significantly higher than similar products on earth, and the taste is not to mention.
Liu Yang, chairman of the Federation of Finance and Finance, immediately thought, this is another source of wealth.
He came down to tell Wen Desi and other senior officials.
Everyone was happy and worried.
Needless to say, he was happy that there was an extra source of wealth.
Everyone will be happy on the road.
The worry is that the transportation capacity of Tongtian Bridge is not enough.
Mr.
Wen and the others are all very knowledgeable people and have eaten a lot of good things, but to be honest, there is really no fruit of this level.
If we really want to introduce it to the market, we definitely don’t have to worry about sales, but what about transportation?
We have to add, we have to add, we have to add.
The overpass is not enough.
One is not enough, so we are building one.
So, that night, while everyone was eating Tiangong flat peaches, they made a plan to build the second Tongtian Bridge.
Of course, this second sky bridge is mainly used for freight.
Because personnel transportation is not considered, the acceleration during launch can be increased to at least 9g, which is 9 times the acceleration of gravity, so its length can be greatly shortened.
About 400 kilometers long is enough.
If you are only transporting durable goods such as metal raw materials, you can add at least 20g, which is enough for more than 100 kilometers.
Although "Pan Taoyuan" is very large, due to the use of highly automated equipment, robots and computer central control, there are not many staff inside.
In theory, only 4 people are enough for each area.
In other words, adding With equipment maintenance personnel, only up to 30 people can take care of all the animals and plants in the entire "Peach Garden".
However, this is also a biological laboratory, so there are still a lot of people, more than a hundred.
Ni Zaizai is a farmer in "Peach Garden".
Well, of course he is a relatively advanced farmer and has a master's degree.
Ya has a master's degree from China Agricultural University, but high education is indispensable in "Pan Taoyuan".
There are many professors here, many PhDs, and more than a dozen double PhDs.
You can encounter several of them even when you go to the toilet.
A master's degree like him was the lowest, so he was assigned to work as a "farmer" to take care of the crops and animals in District 5.
Ni Zaizai walked into the chick farm with a feed tray.
The gravity here was only 0.5 times, so he walked very briskly.
When he first came up, he was still not used to it.
He often hit something in front of him due to excessive force, and his head was hit several times before he got used to it.
"Chirp, chirp, chirp!"
Several chickens and ducks saw Ni Zaizai coming and screamed excitedly at him.
"Stop barking, everyone has it."
Ni Zaizai squatted down and sprinkled the feed in the trough.
The chickens and ducks quickly rushed up to grab the food.
These little animals are all hatched here, and they are considered to be native space creatures.
These guys are very adaptable to the low gravity environment here.
At least they are much stronger than Ni Zaizai.
They have never hit the wall or anything.
After Ni Zaizai finished spreading the feed, he picked up a chick and observed it carefully, and then took out a tape measure to measure it.

After putting it down, he picked up another one, looked at all the chickens and ducks carefully, and measured them again.
Then he took out his notebook and began to write down his observation records.
"Growth and development are normal, body size is significantly larger than that of similar people on earth of the same month and age, body hair is relatively fluffy, and leg muscles show signs of degeneration."
"Hi, Zai Zai" Ni Zai Zai was writing when he suddenly heard someone greeting him.
When I looked up, it was Chi Zhanjiang, a master's student from North China Animal Husbandry University.
"Zhanjiang Zai, you've finished feeding your cows," Ni Zai Zai said with a smile.
Chi Zhanjiang said angrily: "It's done, mother, I'm unlucky today.
I accidentally used too much force when milking just now, and the cow actually kicked me.
Fortunately, I was quick to dodge."
"Hahahaha, you touch and scratch other people's breasts every day, and you are not allowed to kick them anymore."
Ni Zaizai smiled evilly.
"Holy shit, you guy."
Chi Zhanjiang was a little discouraged because he was assigned by his professor to take care of the cows and milk them part-time.
He was nicknamed "Brother Touching the Milk" in this circle, which made him depressed.
So he changed the topic: "Finish it early and watch the news tonight."
"Is there any important news?"
"Hey, it's that German Prime Minister with a mustache who is visiting China."
"Mustache has been here several times.
According to the official, he is considered an old friend of the Chinese people.
What's so strange about his coming?
If their queen comes, you can also take a look.
What's there to see about Mustache?
I'm interested in it.
Men are not interested," Ni Zaizai said disapprovingly
