Doomsday Bunker Upgrade

The glass balls in Qin Lan's photos are called eco-balls, which were a very popular small and fresh decoration before the disaster.

The method is also very simple, just find a transparent glass container, spread a layer of fine sand inside, fill it with about two-thirds of water, then put in small fish and shrimp, and seal the entire container.

The ecological ball produced in this way can maintain the ecological balance for about two months. Although it is necessary to bask in the sun every day to ensure light, and the proportion of small fish, shrimp and algae should be well controlled, but generally speaking, it is only such a simple thing that can maintain The two-month ecological balance is already of considerable research significance.

In fact, the Ecosphere has been a meaningful research project ever since it was first invented by two scientists.

If the eco-ball is compared to a small blue star, the little red shrimp represents human beings.

Therefore, this ecological ball can lead to the current Blue Star. The natural ecological environment is constantly being damaged. If the damage continues and is not improved, all life may be threatened by death.

The idea of ​​this ecological ball just reminds human beings of the importance of maintaining ecological balance to life, and it also reminds people of the interlocking relationship between various creatures on the blue star and the mysteries involved.

At the same time, before the disaster, aerospace research institutes were also conducting research on the ecosphere, in order to use spaceships, space stations, and outer space colonies as containers to build such an ecological environment that can maintain balance and ensure the survival of humans in it.

This coincides with Chen Xin's current goal, and it can also provide him with a lot of reference.

"I saw this kind of small ecological ball in Qingyan's bar before. Do you care about this, Ah Xin?" Seeing that Chen Xin was very concerned about the ecological ball, Qin Lan asked curiously.

Although we are together every day, Qin Lan's main job is to assist in the development and design of Titans. In addition, she is not the kind of character who likes to ask Chen Xin what he is doing every day, so she doesn't know much about Chen Xin's work, but generally knows him. Just doing something.

Chen Xin nodded and explained to Qin Lan: "Recently I'm studying the ecosystem, and this ecosphere is very useful for reference."

"Is the ecological system the ecological cycle mentioned in the previous biology textbooks?" Qin Lan can't be admitted to the civil service and become a special police officer. Of course, she can't be a scumbag. She still understands what these middle school students have learned.

"That's the ecosystem. Now the natural ecology has collapsed, so I plan to build an artificial ecology, but so far, it is difficult to maintain its balance and existence. It always collapses after a few years of operation. It is not as good as this ecological ball Stable." There was a wry smile on Chen Xin's face, not because he underestimated himself, but because the real artificial ecology is not as stable as the ecological ball.

A simple and small ecological ball like this may not last for two or three months, but if it is well controlled, an ecological ball can actually last for more than two to three years, and even larger ones can last for five years. Up to seven years, the longest can persist for more than ten years.

This is obviously much more stable than the ecosystem built by Chen Xin and the others.

Of course, this is mainly due to the difference in complexity between the two. After all, the environment inside the ecosphere is very simple, the number of species is small, and there are few variables that naturally affect the balance. It is not particularly difficult to maintain a balance.

After all, there are only algae, small fish and shrimp inside, and the only thing that can affect its ecological balance is light and temperature. Controlling these two variables is enough to ensure the ecological balance in the ecological ball, until the life of algae or small fish and shrimp run out.

As for reproduction, it is impossible. The space of such an ecological ball is very limited, and it does not support the reproduction of small fish and shrimps or the increase of algae.

Replacing a larger space can improve this point.

Thinking of this, Chen Yu suddenly felt that he could try another method.

He stood up excitedly, hugged Qin Lan and kissed her on the face, then hurriedly rushed to the holographic imaging room.

Qin Lan looked at Chen Xin's hurried look. Although he was a little puzzled and felt helpless at the same time, he still smiled, didn't care, and continued to organize the photos in front of him.

And Chen Xin, who rushed to the holographic imaging room, input his new ideas into the instrument constructed with nano-molecules on the watch, and then projected them in the holographic imaging room.

This time, Chen Xin did not adopt the method of adding everything in from the beginning to build the ecosystem, nor did he use only plants to build the ecosystem, or even directly use the dome city as the basic environment, but chose a A plant or an animal, like making an ecological ball, only encloses a small space and puts two species in it.

In addition, what Chen Xin provided for this "ecological sphere" was only soil, light, and sufficient water resources.

The plants that Chen Xin put into it were only the most common and common grasses, and the animals were rabbits.

Rabbits eat grass, then excrete feces, which are decomposed by bacteria and reabsorbed by grass as nutrients to supply grass growth. This constitutes a cycle. If there is no problem, this should be a stable system.

Of course, if the number of rabbits increases beyond the carrying capacity of the environment, it will undoubtedly lead to the collapse of the entire ecosystem.

However, this was just a simulation experiment. Chen Xin only allowed the rabbits to reproduce in an appropriate amount to maintain the population, and did not allow them to reproduce without restriction.

After all, Chen Xin was very clear about the dire consequences of overbreeding rabbits.

Because the number of rabbits is artificially controlled, this cycle has not been broken. After the number of rabbits reaches the upper limit of the carrying capacity of the environment, it stabilizes, and the cycle can continue forever according to the calculation of the program.

Chen Xin was not surprised by this result, because quite a lot of other variables were ignored, and the whole cycle was just a simple simulation test, and there was no ecosystem at all. I'm making adjustments, if it can crash like this, then there's no need to play.

With this preliminary foundation, Chen Xin can carry out further tests.

That is to no longer artificially control the number of rabbit populations, but put predators in it, and use the predators themselves to control the number of rabbits.

Of course, with the addition of predators, the size of the "ecological ball" becomes narrow, so while adding the predators, Chen Xin also enlarged the size of the entire "ecological ball", improving the carrying capacity of the environment and at the same time The upper limit of the environment load has been increased.

As for the predator Chen Xin put into the "ecological ball", he chose the same common wolf.

Rabbits eat grass, wolves eat rabbits, and finally the corpses and excrement of wolves and rabbits will be decomposed and returned to the earth to become nutrients for grass, thus forming a cycle.

Sorry, I forgot to bring my keys when I went out this afternoon. I was a little uncomfortable after being out in the sun for an afternoon. There is only one chapter today.
