Chapter 94 Aquaponics
Obviously, Li Wensheng originally planned to use a wind turbine to supply power so that his shelter can use all the sufficient electricity, but it is obvious that the harsh environment greatly shortens the service life of the three wind turbines.
It cannot be said that it is completely damaged now, but the paralyzed wind turbine is obviously not a good thing that Li Wensheng can repair by himself.
So he could only rely on the generator originally used as a backup power supply to power his shelter and maintain the operation of his aquaponics system.
This obviously exceeded the consumption limit that Li Wensheng could maintain, causing him to fall into the dilemma of energy shortage.
"Then won't you last long?" Chen Xin couldn't help but worry about Li Wensheng's current situation, especially since he had just obtained the oxygen generator from Chen Xin. Although this thing does not consume that much power, it needs to be turned on all the time.
"Who said no? I have used more than half of the diesel I have stored. If I don't have any supplements, I can't hold on for at most three months." Li Wensheng couldn't help but shake his head, his expression on his face was filled with sadness and helplessness: "I have turned off half of the aquaponics symbiosis system now, and the harvested vegetables and fish have been temporarily processed and stored to reduce consumption. I hope I can hold on for a few more months or repair the wind turbine.
If I really can't hold on, I can only take my wife and children to the official shelter, and I can't watch them starve to death!"
Chen Xin felt a little uncomfortable when he heard Li Wensheng say this, and almost said that he could help Li Wensheng repair the wind turbine, but he still held it back.
Some things can be helped, but some things are better not to be so enthusiastic.
After holding back the help, Chen Xin thought for a while, he still couldn't bear to see him die, so he said to Li Wensheng: "Old farmer, if you have surplus production, try exchanging supplies with the official shelter. I am now using vegetables produced in the greenhouse and the official shelter to exchange supplies, and I can barely maintain it."
Hearing Chen Xin say this, Li Wensheng's face suddenly showed a glimmer of hope, and he hurriedly asked Chen Xin: "How did you change the writer? Can you help me change some resources? If you don't need anything else, just have diesel!"
However, before Li Wensheng finished speaking, he knew that he had said the wrong thing when he looked at Chen Xin staring at him.
Chen Xin did not say much to Li Wensheng, but just reminded him: "The official shelter should be short of vegetables and fresh meat. Although they raise mice and grow mushrooms by themselves, the city government also has an underground planting area at the power plant, fresh vegetables and meat are still relatively scarce. Old farmer, you should be able to exchange the gasoline you need."
"Okay, thank you, the writer! I'll go back first!" Li Wensheng was a little embarrassed because of his words just now, so he carried the oxygen generator that Chen Xin gave him and left Chen Xin's shelter.
Chen Xin also closed the door of the shelter and walked into the shelter with a box of fresh fish.
In fact, it is not impossible for Chen Xin to help Li Wensheng change diesel, but his relationship with Li Wensheng is not as familiar as Mo Qingyan, Ding Ning and Qin Lan. It is no problem to give him directions, but if Chen Xin wants to come forward to help him change gasoline by himself, Chen Xin feels that he should not be too enthusiastic in life.
There have been too many stories like Shengmien fighting Miqiu in history. Although Chen Xin is not stingy in helping others, it does not mean that he will help others selflessly.
After all, Chen Xin exchanged supplies with the Special Police Force, although the fresh vegetables in his hand were needed by the Special Police Force, the main reason for reaching an equal deal was the relationship between him and Ding Ning and Qin Lan. Uncle Ding gave such a relatively generous exchange for Ding Ning and Qin Lan's sake.
If Li Wensheng really can't live a life, Chen Xin will help him change diesel once or twice to make an emergency, but it may be impossible to ask Chen Xin to help him change diesel for a long time to maintain the operation of his shelter.
This kind of thing can be done without recurring. After all, Chen Xin has no reason to consume his favors to help others.
However, the aquaponics symbiosis system mentioned by Li Wensheng gave Chen Xin a great inspiration and temptation, and he might be able to develop a similar three-dimensional agricultural system.
Try it next time you upgrade your shelter?
This thought flashed through Chen Xin's mind and he couldn't help but start to think about it seriously.
While putting the fresh fish that was exchanged in the freezer for freezing, Chen Xin thought about the feasibility of this idea.
The aquaponic symbiosis system is a cyclic composite tillage system that combines two technologies of fish farming and hydroponic cultivation. Its main principle is to decompose ammonia nitrogen in fish manure into nitrite through bacteria, and then decompose it into nitrate by nitrated bacteria. The nitrate can be directly absorbed and utilized by plants as nutrients.
The water absorbed by plants is relatively clean and can be reused to provide fish, so that fish are not changed without changing water and vegetables are not fertilized.
In this way, fish, vegetables, bacteria and the three can form a complete cycle. Before the disaster of sunlight, the entire system can even achieve closed-circuit cycle by feeding fish with endless vegetables. Only 2-3 cubic water bodies can match 20-30 square meters of vegetable cultivation area, which can basically meet the consumption needs of vegetables and fish products for 3-5 people in the family.
In this apocalyptic environment, in order to maintain such a system, fill lights are needed to replace sunlight, and the planting area must be expanded to provide staple food output.
Chen Xin’s current planting greenhouse does not have the conditions to do this. Although he had considered aquaponics when building the shelter, the energy consumption of this equipment far exceeded that of soil cultivation. Considering the issue of energy consumption, Chen Xin gave up this idea and only built an ordinary planting greenhouse.
But now that the system exists, Chen Xin feels that he can still consider upgrading his planting greenhouse to a system of aquaponics.
However, the energy consumption issue is indeed a problem that must be considered. After all, Chen Xin can only barely maintain the operation of the shelter, and the power supply depends entirely on his replacement of gasoline from the SWAT team every month to maintain the generator operation.
Before he upgraded the power system, he did not intend to increase the power burden of the shelter.
So in addition to creating the medical room in the next step, Chen Xin’s primary upgrade goal is the power system.
Although it was determined from the beginning that the power system was the most priority for upgrading, after upgrading step by step, everything else was upgraded, but the power system had not moved.
Although the power system is enough now, Chen Xin decided to upgrade it, at least he had to build the biogas fuel cell to reduce the load on the generator.
Of course, these things are not urgent, now...
Chen Xin looked at the fresh fish that had been put in the freezer and couldn't help swallowing his saliva. He hadn't eaten fish for a long time.
