Doomsday Bunker Upgrade Chapter 54: Foreseeable food crisis

　　 In fact, Mo Qingyan also knows how important it is to have a greenhouse that can produce food in the apocalyptic environment, but the refuge of her family was built when the house was built, and the greenhouse was not considered at that time. Instead, the basement floor was designed as a bar.

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

Of course, this is 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's just a nuclear war or other doomsday disaster, a year or two is enough for them to wait for post-disaster reconstruction or rescue by a search and rescue team.

　　 But now that everyone needs to face a hundred years of extremely cold nights, the ground will be in a frozen soil environment within a hundred years, and it is not suitable for the cultivation of any crops. Human food production can almost be said to be 99%. Completely reimbursed.

　　Under such circumstances, all people can count on is the material reserves before the disaster, and the underground greenhouses built in the shelters that are not so affected by the temperature.

　　 Chen Xin may not know the situation because he is far away from the city, but Mo Qingyan knows some things because he is close to the municipal refuge and shopping center refuge in the urban area. Now the refuge in the urban area Both have begun to control the use of materials.

Although the main source of food 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 Yan Country, the 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 that can be obtained in the current environment. If the management is reasonable and the planting area of ​​100 square meters uses five layers of three-dimensional cultivars in a suitable environment, the yield is even the most conservative one square meter. For 30 kilograms, it can reach 75,000 kilograms a year.

　　 The output is not low, but if you want to ensure the food supply of a refuge, although it is difficult to build a greenhouse in a small refuge, it is not a big problem for them to ensure food supply without a large planting area.

　　 is like a refuge for Chen Xin, a 100-square-meter planting greenhouse, if all mushrooms are grown, enough for Chen Xin to be eaten by one person, and the excess output can be used to make mushroom wine and drown himself.

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

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

　　 After all, at first I heard that one hundred square meters can produce more than 70,000 catties of food a year, but the city has a permanent population of 300,000, thanks to the Yan Guo government "not abandoning one person" before the disaster. According to the policy, at least 90% of the people were able to enter the shelter and survived.

Calculated on the basis that 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 it is no longer possible to grow any crops on the ground, all food sources are underground greenhouses, but obviously there is not such a large place in the refuge for planting greenhouses.

　　 And 360,000 square meters are 3,600 ares, 540 acres, and 36 hectares, which is equivalent to half of the Forbidden City, 1.7 bird’s nests, and 51.4 standard football fields.

　　Such a large area, if it were before the disaster, of course it’s nothing. Excluding the area of ​​rural arable land, just the labor reform farm near the city has 36,500 acres of arable land. Grain output is not a problem at all.

　　 As for planting greenhouses, if you want to repair them on the ground before the disaster, such a large area of ​​planting greenhouses is nothing more than a matter of money, and there will be no construction difficulties.

　　 But in the last days when the disaster has come, because of the severe cold, it is no longer possible to build a greenhouse on the surface. If you want to ensure enough food production, you can only dig enough space underground.

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

　　Even if the major refuges have enough manpower, they may have enough tools in stock before the disaster. It is a very large 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 apocalypse has just begun, and the major shelters have sufficient material reserves, which can still support them for a long time.

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

　　 So it is foreseeable that food will become the most urgent rigid demand in the future, and being able to ensure that you have a stable food supply~IndoMTL.com~ has become the top priority for surviving in this apocalyptic world.

　　 Whether it is Chen Xin or Mo Qingyan, or the people in other refuges, they must solve this problem first if they want to survive in this end of the world.

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

　　"Okay, with Alan's help, the problem with you, Dragon Niang, is solved." Chen Xin looked at Mo Qingyan, and said to her with a smile: "Then you next Just vacate the wine cellar and transform it into a greenhouse."

　　 "Huh, I vacated the wine cellar, so you can remember my collections, right? I tell you, if you want my wine, you can change it with a good one!" Mo Qingyan rushed to Chen Xinheng There was a cry.

Seeing Mo Qingyan's appearance, Chen Xin suddenly laughed: "Don't worry, I will definitely not let you down!"

　　 Regarding the bickering conversation between Chen Xin and Mo Qingyan, Qin Lan just watched from the sidelines, and when the two of them finished talking, she said: "If the two of you have finished talking, shouldn’t you go get A Xin? Did you promise to give us food for the SWAT team?"

　　 Although Chen Xin exchanged supplies with Uncle Ding in the name of Mo Qingyan, both Uncle Ding and Chen Xin understood that the parties involved in the transaction were Chen Xin and the SWAT team.

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

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

　　 Facing Qin Lan’s urging, Chen Xin laughed and took them to his planting greenhouse: "Don’t worry, the vegetables are already ripe. I am harvesting before you come."
