Doomsday Bunker Upgrade Chapter 526: “Eco Ball”

The glass **** that appeared in Qin Lan's photos were called ecological balls, which were a small and fresh decoration that was very popular before the disaster.

The method is also very simple, just find a transparent glass container, spread a layer of fine sand in it, fill it with about two-thirds of the water, and then put in the small fish and shrimp, and seal the whole 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 ratio of small fish, shrimp and algae should be well controlled, in general it is just that simple. The fact that things can maintain an ecological balance for two months is of considerable research significance.

In fact, since the ecosphere was originally invented by two scientists, it has been a very meaningful research project.

If the biosphere is likened to a small blue star, the little red shrimp represents human beings.

So this ecological ball can lead to the current Blue Star. The natural ecological environment is constantly being destroyed. If it continues to be destroyed and not improved, all life may be threatened with death.

The idea of ​​this ecological ball just reminds human beings of the importance of maintaining ecological balance to life, and also reminds people of the interlocking relationship and the mysteries of various organisms on the Blue Star.

At the same time, before the disaster, aerospace research institutions were also conducting research on ecological balls, in order to use spacecraft or space stations and outer space colonies as containers to build such an ecological environment that can maintain a balance and ensure that human beings in it. Survive.

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

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

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

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

"Is the ecosystem the ecological cycle that was taught in biology textbooks in the past?" Qin Lan can 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.

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

Although it is simple and small, it may not be enough for two or three months, but if controlled well, an ecological ball can actually last for more than two to three years, even larger ones. It can be maintained for five to seven years, and the longest can last 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. thing.

After all, there are only algae and small fish and shrimp in it, and only light and temperature can affect its ecological balance. Controlling these two variables is enough to ensure the ecological balance in the ecological ball, until the algae or small fish are small. Shrimp lifespan is exhausted.

As for reproduction, it is impossible. Ecospheres like this have very limited space and do not support the reproduction of small fish and shrimp or the increase of algae.

And replacing the larger space can improve this.

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 rushed to the hologram room.

Qin Lan looked at Chen Xin in a hurry. Although it was a little inexplicable and felt helpless for a while, he still smiled, didn't care, and continued to organize the photos in front of him.

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

This time, Chen Xin did not use the method of adding everything in the beginning to build the ecosystem, nor did he use only plants to build the ecosystem, or even directly used the dome city as the basic environment, but chose One kind of plant and one kind of animal, just like an ecological ball, only a small space is delineated, and two species are put in it.

In addition, all Chen Xin provided for this "ecological ball" was soil, light, and sufficient water resources.

The plants that Chen Xin put into it are just the most common and common grass, and the animals are rabbits.

The rabbit eats grass, and then excretes feces that are decomposed by bacteria, reabsorbed by the grass as nutrients, and supplied to the grass to grow, thus forming a cycle. If there is no problem, this should be a system that can operate stably.

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 is just a simulation experiment. Chen Xin only allowed the rabbits to breed in moderation to maintain the population, but did not allow them to breed unrestricted.

After all, Chen Xin is well aware of the dire consequences of over-breeding rabbits.

Because the number of rabbits is artificially controlled, this cycle is not broken. After the number of rabbits reaches the upper limit of the environment's carrying capacity, ~IndoMTL.com~ will stabilize, and the cycle can continue according to the program calculation.

Chen Xin is not surprised by this result, because a lot of other variables are ignored, and the whole cycle is just a simple simulation test, there is no ecosystem at all, plus Chen Xin It is also artificially adjusted. If this can all crash, then there is no need to play.

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

That is, instead of artificially controlling the number of rabbits, we 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 investing in predators, Chen Xin also enlarged the size of the entire "ecological ball", improving the environmental carrying capacity. At the same time, the upper limit of environmental carrying capacity is also raised.

As for the predators Chen Xin put into the "ecological ball", he chose the equally 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, so the cycle is formed.
