Doomsday Bunker Upgrade

The glass ball appearing in Qin Lan's photo is called the ecological ball, which is a very popular small fresh decoration before the disaster.

The method is also very simple, just find a transparent glass container, spread a layer of fine sand, fill it with about two-thirds of the water, put in the 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 the sun must be basked every day to ensure the light, the ratio of small fishes and shrimps to algae must be controlled, but in general it is only such a simple thing that can be maintained. The two-month ecological balance is already of considerable research significance.

In fact, after the ecosphere was first invented by two scientists, this has always been a very meaningful research project.

If the ecosphere 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, and the natural ecological environment is constantly being destroyed. If it continues to be destroyed and does not improve, all lives may be threatened with death.

The concept of this ecological ball reminds humans of the importance of maintaining ecological balance to life, and also reminds people of the chain relationship between various creatures on the Blue Star and the mystery in it.

At the same time, before the disaster, aerospace research institutions were also conducting research on the ecosphere, in order to build such a balanced ecological environment with spacecraft or space stations and outer space colonies as containers to ensure the survival of humans in it.

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

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

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 personality that likes to ask Chen Xin every day what he is doing, so she doesn't know Chen Xin's work so well, just knows him roughly. What are you doing.

Chen Xin nodded and explained to Qin Lan: "Recently, I am studying ecosystems. This ecosphere is of great reference."

"Ecosystem, is the ecological cycle described in the previous biology textbooks?" Qin Lan can be admitted as a civil servant and become a special police officer. Of course, she can't be a scumbag. She still understands the things that 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 running for a few years. It is not as good as this kind of ecological globe. Stable." A wry smile appeared on Chen Xin's face. It was not that he was arrogant, but that the artificial ecology was not as stable as the ecological ball.

An ecological ball like this may not work for two or three months if it is simple and small, but if it is well controlled, an ecological ball can actually last for two to three years, and even a larger one can last for five months. By seven years, 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 the degree of complexity between the two. After all, the internal environment of 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 and small fishes and shrimps, and only light and temperature can affect its ecological balance. Controlling these two variables is enough to ensure the ecological balance in the ecosphere until the life of the algae or small fishes and shrimps. 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 it with a larger space can improve this.

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

He stood up excitedly, and after holding Qin Lan and kissing her on the face, he rushed to the holographic imaging room.

Qin Lan looked at Chen Xin in a hurry. Although he was a little inexplicable and felt helpless at the same time, he still smiled and 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 the wristwatch, and then projected them in the holographic imaging room.

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

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

The plants that Chen Xin invested in are just the most common and common grasses, and the animals are rabbits.

Rabbits eat grass, and then excrete feces which are decomposed by bacteria, which are absorbed by the grass as nutrients and supplied for grass growth to form a cycle. If there is no problem, this should be a system that can operate stably.

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

However, this is only a simulation experiment. Chen Xin only allowed the rabbits to reproduce in an appropriate amount to maintain the population size, and did not allow them to reproduce unrestrictedly.

After all, the terrible consequences of rabbit overreproduction, Chen Xin still knows very well.

Because the number of rabbits is controlled artificially, this cycle has not been broken. After the number of rabbits reaches the upper limit of the carrying capacity of the environment, UU Kanshu www.uukanshu.com will stabilize, and the cycle can continue according to the calculation of the program.

Chen Xin was not surprised by this result, because quite a few other variables were ignored, and the whole cycle was just a simple simulation test. There was no ecosystem at all, plus Chen Xin was also artificial. In the process of adjustment, if this can break down, then there is no need to play.

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

That is to no longer control the number of rabbits in an artificial way, but put predators in it, and the predators themselves control the number of rabbits.

Of course, with the addition of predators, the size of the "ecological sphere" appears to be narrow. Therefore, while investing in predators, Chen Xin also enlarged the size of the entire "ecological sphere", which improved the carrying capacity of the environment while also increasing the environmental carrying capacity. Raise the upper limit of environmental carrying capacity.

As for the predators that Chen Xin invested in 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 the grass. In this way, a cycle is formed.
