Doomsday Bunker Upgrade Chapter 494: The significance of the ecological greenhouse
The ecological greenhouse of the scientific research center is not the same as the traditional greenhouse, and it is also quite different from the ecological greenhouse before the disaster.
Greenhouses in the traditional sense are mainly used to increase the temperature and artificially change the growing environment of crops.
Although the ecological greenhouses before the disaster are different, they are actually used for this purpose, but relatively speaking, the functions will be more comprehensive.
Chen Xin remembers that according to the information he found, there is even an ecological greenhouse with its own solar panels, which provides energy for the greenhouse through solar power generation, and makes full use of natural resources to increase the yield of crops in the greenhouse.
But that's unlikely now.
Including the newly built greenhouses by the state, the most essential difference between these newly built greenhouses after the disaster and the previous ones is the walls.
Most of the traditional greenhouses are made of transparent film, which is low-cost and easy to maintain. The use of grass thatch or thermal insulation quilt to maintain the temperature is indeed enough in the past, and it has enough thermal insulation.
However, if you want to maintain the temperature in the environment of minus tens of degrees, this is not what traditional greenhouses can do. Even the ecological greenhouses in the past used plexiglass and transparent materials at most. Materials such as plastics, the thermal insulation performance does not exceed too much.
The four walls of the greenhouse here in the scientific research center are made of high-performance thermal insulation materials as interlayers. The outer layer is made of low-temperature-resistant metal materials, and the inner layer is made of composite materials. Can prevent the loss of internal temperature and water vapor.
Because there is no sunlight outside, the current ecological greenhouse does not consider the issue of light transmittance. Instead, it is necessary to reduce the escape as much as possible in order to save.
In addition to the differences in the building structure, the bigger difference lies in the interior.
It not only adopts a variety of technologies such as soilless cultivation, three-dimensional planting, ecological agricultural breeding, etc. to upgrade the original flat planting area into a three-dimensional planting system, but also forms a cycle between various crops, which can form an organic planting system. overall.
With the continuous addition of the three necessary conditions of light and mild water, although the ecological greenhouses in the scientific research center cannot be said to be able to farm indefinitely, there will be no problems for at least ten or twenty years.
The expected goal of the research team led by Professor Li is that there will be no circulation problems within 50 years, so that the ecological greenhouse can still operate normally without changing crops except for mechanical maintenance.
As for the maintenance of the ecological greenhouse, it has been fully mechanized with the help of Chen Xin.
Mechanical harvesting, mechanical sowing, mechanical irrigation, and mechanical feeding... In the entire ecological agriculture system, all parts that require human labor have been replaced by mechanized operations under Chen Xin's will, and everything has become automated.
In fact, the ecological greenhouse here in the scientific research center is indeed fully automatic. It only needs to set the planting mode and ecological system, provide original crop seeds and animal seedlings, and ensure the supply of light, temperature and water. Ecological greenhouses can operate on their own.
Professor Li and the others are looking for 50 years without problems, which means that apart from mechanical failures, the entire ecological greenhouse can operate by itself for 50 years without problems.
To achieve this goal, Professor Li and his team carefully selected all the crop seeds.
They did not choose those seeds that were artificially cultivated in the past with high yield but could not inherit the traits for a long time, but those seeds with stable traits that could be sown all the time without obvious yield reduction.
Moreover, careful research on the ecological dependence between crops was carried out, which enabled the construction of this fully automated ecological greenhouse in the current scientific research center.
The animal seedlings used in the ecological greenhouses are also excellent breeds cultivated by optimizing the traditional livestock seedlings with the help of the equipment used by Chen Xin to breed genetically modified wolf dogs.
It's just that animals are very different from plants, and they need someone to take care of them.
Although the automatic machinery of the ecological greenhouse can provide them with the water and food they need to survive, in the event of diseases, etc., they still have to be handled by humans.
It has to be said that this is already very similar to the automated agriculture in science fiction.
The ecological greenhouse, which devoted a lot of effort to Professor Li and Chen Xin, did not let them down. Not only could it be self-sustaining all the time, but it could also produce a steady stream of fruits and vegetables, as well as a large amount of food every month. Agricultural and sideline products such as crops and eggs, milk and meat.
According to the calculations of Chen Xin and Professor Li, such a greenhouse can support at least 3-5 people per mu of land.
Don't think this number is very low. If you follow the traditional agricultural model, if only rice is grown on an acre of land, two crops a year, 1000 catties of rice per season, will produce 500 to 600 catties of rice, 1000 catties of rice a year. , it can barely meet the needs of two or three people for rice.
But it is impossible for people to only eat rice and not eat vegetables and other meat.
So theoretically speaking, if you want to feed a person and meet his dietary needs, one acre of traditionally planted land is simply not enough.
Now, what this kind of ecological greenhouse can provide is completely different.
First of all, the ecological greenhouse that can carry out three-dimensional planting and ecological agriculture can completely turn the original one mu of land into several mu of land~IndoMTL.com~ will greatly increase the yield of crops.
Not only that, the ecological system built in the ecological greenhouse can produce a wide variety of vegetables and fruits, eggs, milk and meat obtained by raising poultry and livestock, as well as other agricultural and sideline products.
And the existence of abundant food, especially meat, can greatly reduce people's demand for a single food.
So in terms of how many people one mu of land can support, of course, the ecological greenhouse wins.
However, correspondingly, the maintenance cost of the ecological greenhouse has also been increased a lot.
In the traditional farming method, one acre of land can complete all the work by one person.
But for the ecological greenhouse, if there is no fully automatic machinery provided by Chen Xin, and it is completely maintained by manpower, maybe three or five people may not be able to maintain the operation of the ecological greenhouse with an area of one mu, and these people must also have enough knowledge that enables them to deal with a variety of problems.
It's just that although the investment cost is high, the ecological greenhouse is also a huge piece of good news for the current situation in Yan Kingdom.
Because for the current Yan Kingdom, the manpower needed to maintain the operation of an ecological greenhouse is secondary, and obtaining more food output is the main thing.
After all, in the end times, manpower is very worthless, but food is very valuable.
It is precisely because of this that the top management of the Yan Kingdom pays special attention to ecological greenhouses, and plans to use this model to build new ecological greenhouses in various places to produce more food.
