Doomsday Bunker Upgrade

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 they will be more comprehensive in function.

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 these are now unlikely.

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 built with transparent films, which are low-cost and easy to maintain. The use of straws or thermal insulation quilts is used to maintain the temperature.

However, if you want to maintain the temperature in an environment of minus tens of degrees, this is not what traditional greenhouses can do. Even in the past, ecological greenhouses used plexiglass, transparent plastics and the like as building materials at most. The material, the thermal insulation performance does not exceed too much.

The four walls of the greenhouse here in the scientific research center are all 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. Loss of temperature and water vapor.

Because there is no sunlight outside at all, the current ecological greenhouse does not consider the problem 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, and ecological agricultural breeding to upgrade the original flat planting area into a three-dimensional planting system, but also allows various crops to form a cycle, which can form an organic whole.

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. able to operate on its 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.

Instead of selecting seeds that were artificially bred in the past with high yields but could not inherit the traits for a long time, they selected seeds with stable traits that could be sown all the time without significant yield reduction.

In addition, careful research on the ecological dependence between crops was carried out, which enabled the construction of this fully automated ecological greenhouse of the current scientific research center.

The seedlings of the animals 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., it is still up to humans to deal with them.

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 disappoint them. Not only can it sustain itself, but it can also continuously produce fruits and vegetables, as well as a large amount of grain crops and eggs every month. Agricultural and sideline products such as 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 one mu of land, two seasons a year, 1000 catties of rice per season, five or six hundred catties of rice, 1000 catties of rice a year, it is possible Barely enough to meet the rice needs of two or three people.

But it is impossible for people to only eat rice and not eat vegetables and other meat.

Therefore, in theory, to feed a person and meet his dietary needs, one acre of traditionally planted land is simply not enough.

But 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, and greatly increase the output 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.

The existence of rich food types, especially meat, can greatly reduce people's demand for a single food.

Therefore, in terms of how many people can be supported by one mu of land, of course, the ecological greenhouse wins.

However, correspondingly, the maintenance cost of ecological greenhouses has also increased a lot.

In the traditional farming method, one mu of land can do 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, 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. They can deal with all kinds 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 state of Yan, 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 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.
