Doomsday Bunker Upgrade

In fact, Mo Qingyan also knows how important it is to have a greenhouse that can produce food in the apocalypse environment, but her shelter was built when the house was built. The first floor is designed as a bar.

This also led to the fact that Mo Qingyan's sanctuary had no self-sustaining ability in terms of food.

This is of course not a problem in the short term. Whether it is exchanging materials with others or obtaining food in other ways, it can be sustained.

Even because there is enough underground space, Mo Qingyan has a lot of supplies, enough for her, Mo Qingxin and Ding Ning to eat for two years.

If it was just a nuclear war or other doomsday disaster, a year or two would be enough time for them to wait for post-disaster reconstruction or rescue by a search and rescue team.

But now everyone needs to face the extreme cold and long night that lasts for a hundred years. The surface will be in a frozen soil environment within a hundred years, and it is not suitable for the cultivation of any crops at all. It can be said that almost 99% of human food production has been completely reimbursed. .

In such a situation, all one can count on is the pre-disaster stockpile and the underground, less temperature-affected greenhouses built in the shelter.

Chen Xin's side may not know the situation because it is far from the urban area, but Mo Qingyan knows a little about the situation because it is close to the city government shelter and the shopping center shelter in the urban area. Now the shelters in the urban area have begun. Control the use of materials.

Although the main food source is still the food reserves before the disaster, it has also begun to match the mushrooms grown in the greenhouse and the mice raised in the food.

In the Yan Kingdom, mushroom cultivation technology is quite mature, which is why the government chooses to use mushrooms as the main food source for post-disaster shelters.

Mushrooms are the main source of food available in the current environment. If the management is reasonable and in a suitable environment, if the planting area of ​​100 square meters adopts five layers of three-dimensional cultivation, the yield is even the most conservative 30 catties per square meter. Calculated, it can also reach 75,000 pounds a year.

This output is not low, but if you want to ensure the food supply of a shelter, although it is difficult to build a greenhouse in a small shelter, they do not need a large planting area to ensure the food supply.

It's like Chen Xin's sanctuary, a 100-square-meter greenhouse, if all kinds of mushrooms are used, enough for Chen Xin to eat to death, and the excess output can be used to make mushroom wine to drown himself.

But for large shelters, the problem is more serious, and the bigger the shelter, the more serious the problem.

Because the more people need more food, and the required greenhouse area will also be larger.

After all, it might seem a lot to hear that 100 square meters can produce more than 70,000 catties of food a year, but the city has a resident population of 300,000, thanks to the government's policy of "not abandoning one person" before the disaster. At least 90% of the people were able to enter the shelter and survived.

If one person consumes one ton of food a year, 270,000 people need at least 360,000 square meters of mushroom cultivation area to meet the consumption.

Because no crops can be grown on the surface, all food sources are underground greenhouses, but there is obviously no such a large place in the shelter to arrange a greenhouse.

The 360,000 square meters are 3,600 ares, 540 mu, and 36 hectares, which are equivalent to half the Forbidden City, 1.7 bird's nests, and 51.4 standard football fields.

Such a large area, if it was before the disaster, is of course nothing. Not counting the area of ​​rural arable land, it is only the labor reform farm near the city that has 36,500 mu of arable land, and grain output is not a problem at all.

As for building a greenhouse, if you want to build it on the ground before the disaster, such a large area of ​​​​the greenhouse is nothing more than a matter of money, and there will not be any difficulties in construction.

But in the last days when the disaster has come, because of the severe cold, it is impossible to build a greenhouse on the surface. To ensure enough food output, you can only dig enough space underground.

It takes a long time to dig out such a large area of ​​underground space.

Even if the major shelters have enough manpower, they may have stocked up enough tools before the disaster. It is a very big project to dig out such a large space.

In other words, if there are no other factors in the future, food shortages will inevitably be a problem that major shelters will face.

Fortunately, the end of the world has just begun, and the major shelters have sufficient material reserves, which can still support a relatively long period of time.

This period of time is prime time for various shelters. Whether they can cope with the food crisis that will arise depends on whether they can dig enough greenhouses during this period.

Therefore, it can be foreseen that food will become the most urgent need in the future, and ensuring that you have a stable food supply that you can obtain will become the top priority for people who want to survive in this apocalypse.

Whether it's Chen Xin, Mo Qingyan, or people in other shelters, if they want to survive in this apocalypse, they must solve this problem first.

Fortunately, for Chen Xin, with the help of the system, food is no longer a problem for him.

"Okay, with Alan's help, this time, Long Niang, your problem is solved." Chen Xin looked at Mo Qingyan, and said to her with a smile: "Then you just need to Empty the wine cellar and turn it into a greenhouse."

"Hmph, I vacated the wine cellar, so you can remember my collection, right? I tell you, if you want my wine, you can exchange it for something good!" Mo Qingyan snorted at Chen Xin.

Looking at Mo Qingyan's appearance, Chen Xin suddenly laughed: "Don't worry, I will definitely not disappoint you!"

For the bickering conversation between Chen Xin and Mo Qingyan, Qin Lan just watched, and when the two finished talking, she then said: "After the two have finished talking, should you go and get Ah Xin? Is it our special police team's food?"

Although Chen Xin exchanged materials with Uncle Ding in the name of Mo Qingyan, both Uncle Ding and Chen Xin knew that the two sides of the transaction were Chen Xin himself and the SWAT team.

After all, although Uncle Ding is the captain of the SWAT team, he can't bring out so many materials, and he can't take so many vegetables to eat alone. Therefore, he collects materials in the name of the SWAT team and exchanges the vegetables for the SWAT team. It has become inevitable for the team to improve the food.

So Qin Lan said that there is no problem at all.

Facing Qin Lan's urging, Chen Xin laughed and took them to his greenhouse: "Don't worry, the vegetables are all ripe, I was harvesting them before you came."
