..................................................................

On January 17, 2780 (1939), the Tiangong-1 space station group, the "Pan Taoyuan" space farm.

With the increase of space buildings, Tiangong-1 is now not just a space station, but a space station group! Because the name here is Tiangong-1, so those who have good deeds have given different nicknames to various functional modules as a difference.

For example, the main body of the space station, which is dominated by various laboratories, is called "Lingxiao Palace", and there are the following functional buildings around it: "Nantianmen" is the spacecraft berthing center for the entry and exit of the sky crane and spacecraft; the living and rest area is called "Qionghua Palace"; the part that is used as a space smelter is called "Tushi Palace"; there is also the "Tongming Palace" as a silicon wafer production base; and the "Baoguang Palace" as an optical fiber production base...... And so on, and the "Pan Tao Yuan" is a space station used as a space farm.

Later, the nicknames of these places became louder and louder, and the officials recognized them, so they officially upgraded these nicknames as the code names of these functional modules.

"Space Farm" is not actually a formal name, but a general name, its scientific name is "controlled ecological life protection system", which is to rely on the propagation of green plants (vegetables, algae, etc.) in space to solve the supply of the most basic materials such as food, oxygen and water needed by astronauts on the spot, which is one of the key technologies and problems to achieve long-term manned interstellar travel and migration in the future.

Space is the future home of mankind, and in order to live in space for a long time, it is not enough to rely on the earth's sustenance, it is necessary to turn space into an oasis and establish space farms, so that at least part of the food can be self-sufficient.

In China's sky plan, in the near future, it is necessary to land people on the moon, Mars and even other planets, which requires a large number of supplies, if only rely on ground supply, then it will need a huge supply team to transport back and forth, not only the transportation cost is expensive, but also technically difficult to guarantee.

The space farm can use the photosynthesis and transpiration of higher plants such as crops and vegetables to produce food, oxygen and water, and use the degradation of special microorganisms to decompose and reuse biodegradable wastes, which can realize the closed cycle of substances in the system. In this way, only a small amount of stored food and water can meet the needs of the crew, which provides a good solution for completely solving the supply problem of long-term manned spaceflight.

In the history of the original space-time, since the advent of artificial satellites, scientists have begun experiments on plant cultivation in space. The United States, Russia and other countries have tried to plant and cultivated more than 100 kinds of plants, such as peas, wheat, corn, rice, onions, orchids, and tulips, on the space station to study the influence of various factors on plant growth during space flight.

Soviet cosmonauts sowed wheat, onions, orchids and other plants during their long life on the Salyut and Mir space stations, and the results showed that the plants grew faster and matured earlier than on Earth.

The United States has also conducted experiments on planting pine, oats, mung beans and other plants in space laboratories and space shuttles, and found that the growth of these plants has not only not been affected under weightless conditions, but also has a generally higher content of protein and other nutrients compared with similar crops grown on the earth. This shows that it is feasible to grow crops in space and can increase yields. At the same time, the United States and Russia have also conducted animal breeding experiments in space, and the results have proved that fruit flies, spiders, fish and other animals can grow and reproduce as freely as on the ground.

In a space farm, plants can grow in sand or foam, or they can hang in the air, and plants can survive, develop, and grow in weightlessness in space as long as they have water, nutrients, and support. And the wind and rain are smooth, and the season is highly productive. Cows, sheep, chickens, fish and other animals on the farm can also grow normally, providing fresh vegetables, fruits, and abundant meat, eggs, milk and other foods for space residents.

By the 22nd century, human footprints had spread all over the galaxy, and they had a wealth of experience in raising and cultivating animals and plants in space. In the 23rd century, when he traveled to the 23rd century, people further discovered that if human beings are in an environment where there are no other organisms for a long time, it is easy to replace depression, and this special mental illness is called "biological environment lack depression". Therefore, international organizations and governments at that time made it mandatory that all places where people reside outside the earth for a long time must be equipped with a small biological environment - a small ecosphere, where all kinds of animals and plants can be raised. That's why there's a zoo and botanical garden on the base of the building.

China's aerospace on this plane, because of the guidance of Wen Desi, a future person, has taken a lot of detours, so it has formulated a plan for space breeding of animals and plants from the beginning. On the one hand, it is to create a small biosphere 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, if there are no abundant ingredients, how can they be worthy of this title? Even if there are no conditions, it is not impossible to live a hard life, but under the conditions available, the astronauts are still allowed to eat "toothpaste" every day, which is not the style of China, nor is it the style of President Wen.

This kind of astronaut-specific "toothpaste" is very high, but it is the most elementary space convenience food, it does achieve nutritious, caloric sufficient, can fully meet the survival needs of human beings, but the taste and texture, forget it, it's all tears. If you are interested, you can try it yourself, it is very simple, it is to mix rice flour or flour with surimi, minced meat, vegetable puree, fruit puree plus cooking oil and condiments, and boil it into a paste. It's almost like this.,It's also sold on the Internet if it's troublesome.,Eat it once or twice may feel fresh.,If you eat it for a few more days.,It's guaranteed to want to vomit when you see it.。

The "Pan Tao Garden" 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 the astronauts to go to the "Pan Tao Garden".

The structure of the whole "Pan Tao Yuan" is like a huge wheel composed of four concentric circles, and the "Pan Tao Yuan" is constantly rotating clockwise, so that it produces artificial gravity. The "axle" is divided into two layers, the inner part is the gravity-free zone, which is fixed and immobile, as a power zone and a passage zone. The outer layer is connected to the outer rim by eight "spokes" and rotates, so here is the microgravity zone, and the gravity is 0. 05G, which is five times the gravity.

Then the four layers of rims because of the linear speed is different, so they correspond to different gravity, the diameter of the outermost circle is 300 meters, according to the linear speed of nearly 8 meters per second, about 120 seconds to rotate for a week, that is, 0. 8x gravity. Then it descends in order until the innermost circle is 0. 2x gravity. Of course, this gravity can also be adjusted, just adjust the speed to easily change the gravity.

"Pan Tao Garden" is divided into six zones according to the different gravity zones composed of four layers of concentric circles and wheel axles, and each area is home to different animals and plants. "Pan Tao Yuan" is said to be a farm, but it is also a large biological laboratory, 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 called "Pan Tao Garden", peaches are naturally indispensable in it. However, only a small part can be eaten at this time, because there are only 20 mature peach trees that can bear fruit, and the rest of the peach trees are still seedlings at different stages. It takes three years for peach trees to bear fruit, and even if they grow faster in space, they will eat the second batch of peaches from the peach trees, at least until next year.

Some people may ask, why not just send the tree that can bear fruit directly up? Yes, there must be no problem in sending it, although the capacity of the crane is enough, but the adult peach tree takes up too much space, and now the crane capacity is so tight that it is good, how can there be so much free space to send you a large number of adult peach trees?

Have you ever seen the Spring Festival. That's right, now the bridge is like the Spring Festival, every car is full, and the staff just arranges the shift is enough to spend their minds, and they can't wait for a cubic meter to be used as a few cubic meters. How much space does a mature peach tree have? So except for the first 20 mature peach trees, the others are seedlings and even seeds at different stages.

However, the first batch of peach trees has borne fruit so far, and half of this batch of space peaches was left as a gift for the Tiangong-1 staff to eat, and half was sent back to Earth as a gift. These peach trees were originally selected and of good seeds, and under the conditions of microgravity, their peaches were even bigger, and the largest one was the size of a small watermelon, and there were more than 5 kilograms of peaches after being weighed!

This giant peach and a few other slightly smaller peaches were given to Mr. Wen by the Space Center, and Mr. Wen gathered all the central high-level and relevant major scientific researchers to share these super peaches together. After everyone ate it, they were full of praise, and they all said that this thing was much more delicious than the earth, and it really deserved to be a peach on the heavenly palace. In addition to the psychological factors of eating strange, the quality of this peach itself is indeed very strong, after testing, it was found that the sugar content and nutritional content of this peach are significantly higher than similar products on the earth, and the taste is not to mention.

Liu Yang, chairman of the Federation of Finance and Finance, immediately thought that this Nima was another source of wealth! When he came down to Wen Desi and several other high-level officials, everyone was happy and worried, and it was needless to say that there was no need to say that everyone would be happy if there was a lot of money. This is worrying, of course, the capacity of the bridge is not enough. Mr. Wen and several of them are knowledgeable people, and they have eaten a lot of good things, but to be honest, there are really no fruits of this level. If you really want to put it to the market, you don't have to worry about the market, but what about this transportation?

There are not enough bridges, one is not enough, we are building one!

So, that night, while eating the peaches of the Tiangong Palace, everyone set the construction plan for the second Tongtian Bridge. Of course, this second bridge is mainly used for freight, because the acceleration during launch can be increased to at least 9G, that is, 9 times the acceleration of gravity, so its length can be greatly shortened. Probably 400 kilometers long is enough. If you only transport durable goods such as metal raw materials, you can add at least 20G, which is enough for more than 100 kilometers.

..................................................................

Although the "Pan Tao Garden" is very large, but due to the use of highly automated equipment, robots and computer central control, so there are not many staff inside, theoretically only 4 people in each area are enough, that is to say, plus equipment maintenance personnel, the whole "Pan Tao Garden" only needs 30 people at most to take care of all the animals and plants. However, this is also a biological laboratory, so there are still quite a few people, more than 100.

Ni cub is a farmer in the "Pan Tao Garden", well, of course, he is a more senior farmer, a master farmer. Ya is a master's degree from China Agricultural University, but the most important high degree in the "Pan Tao Garden", there are groups of professors, piles of doctors, more than a dozen double doctors, and you can meet several in the toilet. A master's degree like his was still the lowest degree, so he was sent to the "farmer" to take care of the crops and animals in the fifth district.

Ni Cub walks into the nestling farm with a feed tray, where the gravity is only 0. 5 times, very brisk to walk. When he first came up, he was still very unaccustomed to it, and often because of too much force, he hit something in front of him headlong, and he was hit by several bags on his head before he could get used to it.

"Chirp, chirp......" A few chicks and ducklings saw Ni Cub coming, and shouted excitedly at him.

"Don't scream, there's all of them!" Ni cub squatted down and sprinkled the feed in the trough, and the chicks and ducklings rushed up to grab the food. These critters are all hatched here, and they are considered native space creatures. These guys are very adapted to the low-gravity environment here, at least much stronger than Ni Cub, and they have never hit the wall or anything.

After the cub finished sprinkling the feed, he grabbed a chick and observed it carefully, and took out a tape measure to measure it. After putting it down, he grabbed another one, looked at all the chickens and ducklings carefully, measured them again, and then he took out his notebook and began to write down the observation record.

“...... It grows normally and is significantly larger than its planetary counterparts at the same age of the same month...... The body coat is fluffy, and the leg muscles show signs of degeneration......"

"Hey, cub!" Ni cub was writing, when he suddenly heard someone greet him. When I looked up, it was Chi Zhanjiang, a master student from North China Animal Husbandry University.

"Zhanjiang Tsai, have you finished feeding your cows?" said Ni cub with a smile.

Chi Zhanjiang said angrily: "It's over, damn, I'm unlucky today." When I was milking the cow just now, I accidentally used too much force, and the cow actually kicked me, but fortunately, the labor and management flashed quickly......"

"Hahahaha, you touch and scratch other people's every day, and you don't allow them to kick it......" Ni Cub smiled evilly.

"Bah, you guy......" Chi Zhanjiang was a little discouraged, because he was arranged by his own professor to take care of the cows and milk them part-time, and he had the nickname of "touch ##奶哥" in this circle, which made him depressed.

So he diverted the topic: "Finish it early and go watch tonight's news......"

"Any important news?"

"Hey, it's the German mustachioed prime minister visiting China......"

"The mustache has been here several times, according to the official words, he is an old friend of the Chinese people, what's so strange about coming? If their queen comes, you can also take a look, what is there to see about the mustache, I'm not interested in men......" Ni cub said disappretently.
