The rise of nanometers

Below Yingzhou Island.

There is hot and sticky air here, and there is also a paradise-like existence - the Venus Agricultural Experiment Test Site.

Venus Agricultural Experimental Testing Ground is a large-scale agricultural testing ground established at the beginning of this year. This testing ground is located on the ground and has an internal usable area of ​​3,000 acres.

Although there are currently only two space agriculture researchers working here, it plays a vital role in the future of Venus.

If humans want to immigrate to alien planets, in addition to overcoming various harsh natural environments, there are also gravity and food issues.

Although the distance between Blue Star and Venus is the closest planet, it was more than 40.5 million kilometers at the closest point, which is equivalent to 1012.5 times around the equator of Blue Star.

Not to mention, when the distance between the two sides is the furthest, it reaches 247.1 million kilometers, and there is a sun in the middle.

With such a long distance, it was okay when the population was small. Once the population increased, the food problem would be a big trouble.

So the Venus Agricultural Test Site came into being.

This is also the reason why Yingzhou Island City is suspended in the Antarctic Circle of Venus.

We all know that the gravity of a planet has certain differences in various regions.

Taking Blue Star as an example, the gravity near Blue Star's equatorial sea level is 9.78; while the gravity near Blue Star's polar sea level is 9.832.

The difference between the two is 0.052.

Similarly, another factor that affects gravity is altitude. At the same latitude, the gravity in lowland areas of the planet will usually be higher, while the gravity in plateau areas will be relatively lower.

In other words, on a planet, the surface gravity is the lowest in the equatorial plateau areas; the surface gravity is the highest in the polar sea levels or basins.

According to this rule, the place on Venus with the highest gravity is naturally the low-lying basin within the Antarctic Circle of Venus.

Why choose the area with the highest gravity on Venus?

Because the average surface gravity of Venus is 8.87, which is about 0.937 lower than the average surface gravity of Blue Star, which is 9.807.

If we look at the equatorial region of Venus, the gravity gap between the two will be even greater.

After a series of tests, the Ministry of Space Affairs obtained the gravity details of Venus around the world and found an area closest to the gravity of the Blue Star.

The Shennong Basin in the Antarctic Circle of Venus. Although this basin is not on the South Pole of Venus, there is a huge mass tumor underground, causing the gravity here to be higher than other areas in the Antarctic Circle.

The gravity measured here is 9.054.

This gravity value is about 0.726 lower than the minimum surface gravity of Blue Star, which is 9.78.

At this time, many vegetables and fruits have been grown in the agricultural testing site, including cucumbers, tomatoes, cabbage, broccoli, green peppers, bell peppers, cabbage, pumpkins, carrots, etc.

There are also potatoes, sweet potatoes and millet as food crops. As for rice and wheat, we need to wait for the arrival of new equipment next year.

In addition to vegetables, fruits, and food crops, there are also seaweed cultivation cabins specially transported from Blue Star, which can be used to produce various edible seaweeds.

In addition, when it comes to raising animals, after all, a purely plant-based diet can lead to malnutrition and even mental problems.

Since the birth of Blue Star, the ancestors of mankind have continued to evolve. As omnivorous animals, humans have engraved meat-eating into their genes. If they do not eat animal food for a long time, the consequences will be the degradation of the entire group.

Don’t think this is alarmist. Look at the intelligence of pigs, dogs, and mice, which are also mammals. They are obviously higher than those of horses, cows, and sheep.

There is an inherent biological logic to this.

That is the efficiency of obtaining energy through food. Plant food can provide too little energy, and large amounts of food must be eaten for a long time. This will make it difficult for the brain to obtain energy to compete with carnivorous animals.

You know, the human brain requires a lot of energy. If you don't eat meat, over time, the brain can only reduce the energy consumption of the brain in order for the body to survive.

Insufficient energy supply to the brain will result in a decline in brain function. After all, the universe is energy-conserving and does not exist in the first place. Creatures that require both brain work and low-consumption brains.

If the Venus Zone is to accommodate a large population, vegetables and fruits, carbohydrate staple foods, and high-protein and high-fat meats are all indispensable.

Therefore, the Venus agricultural test site must consider raising animals. However, transporting large animals to Venus not only weighs a lot, but also faces serious road damage and environmental adaptation problems.

Under necessity, the Ministry of Aerospace selected fish, insects, and mice that were easy to transport based on research data from the Lunar Agricultural Science Institute.

Currently, there are four fish box breeding cabins in the Venus Agricultural Test Field, which are used to breed tilapia, pond lice, conger eels, and pomfret respectively.

In terms of insects, there are also four breeding cabins, respectively breeding locusts, bamboo worms, scorpions, and silkworms.

Finally, there are four breeding cabins for breeding rats. Although they are rats, they are not ordinary rats, but specially bred meat rats.

This kind of meat rats have been screened and bred for dozens of generations in Blue Star, and they are isolated from the natural environment. There are no plague bacteria and parasites in their bodies.

There are no alien microorganisms on Venus, and they basically don’t need to worry about microbial infections here.

Although insects and fish can also provide protein, fat, vitamins and minerals, the protein in insects, also known as heterologous protein, is somewhat different from the mammalian protein we often eat.

This is why many people suffer from allergies and diarrhea when eating seafood or insects. This is because many people in the human race cannot adapt to foreign proteins.

Not to mention insect and fish protein, even if it is milk produced by mammals, many people will have diarrhea after drinking it.

Adaptive evolution cannot be achieved overnight, so mammalian protein is an essential food.

The specially bred meat rats have become one of the few self-sufficient sources of mammalian protein on Venus at this stage.

Of course, the aerospace department is already preparing breeding cabins for broilers and laying hens, and is preparing to add protein types to Venus, but it just needs time to gradually improve.

For astronauts on Venus, eating rat and chicken will basically be a normal diet in the future.

In fact, once you get used to it, you don’t have much psychological pressure. After all, the astronauts know the breeding process of these meat rats. They are even cleaner and hygienic than many breeding farms on Blue Star. The meat rats themselves have been screened for dozens of generations. bred.

Moreover, meat rats reproduce and grow very fast, and with their strong environmental adaptability, they can give birth to 6 to 8 litters a year, with 5 to 10 rats per litter, if the feed supply is sufficient.

From the moment a mouse is born, it only takes 2 to 3 months to develop into a state where it can reproduce, and at the same time it has almost entered the stage of maximum weight.

Meat rats are specially bred and can grow to 3 to 4 pounds in an average of about 7 weeks, with a meat production rate of about 72 to 75%.

Anyway, the two agricultural researchers often use it to make hot pot and barbecue. The taste and texture are close to pork. On Venus, where pigs cannot be raised, this kind of meat rat is also called "little pig" by astronauts.

With the Venus agricultural test site put into operation, the supply transported by the Federation from Blue Star to Venus in the future will reduce a lot of food that is difficult to preserve.

In terms of developing agriculture, Venus has more advantages than the moon and Mars.
