Doomsday Bunker Upgrade

In fact, Mo Qingyan also knows how important it is to have a greenhouse that can produce food in the apocalyptic environment, but her refuge was built when the house was built. At that time, the greenhouse was not considered, but the underground The ground floor is designed as a bar.

　　 This also resulted in Mo Qingyan's refuge without food self-sustainability.

　　 This is certainly 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 of the sufficient 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 disasters, one or two years is enough for them to wait for the reconstruction after the disaster or rescue by the search and rescue team.

But now everyone needs to face the extreme cold and long night that lasts for a hundred years. The ground will be in a frozen environment within a hundred years, which is not suitable for the cultivation of any crops. Almost 99% of human food production is 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 something because he is close to the municipal refuge and shopping center refuge in the urban area. Now the refuge in the urban area has begun. Control the use of materials.

　　 Although the main source of food is still the food stored before the disaster, it has begun to mix the mushrooms grown in the greenhouse and the rats 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 output is even the most conservative 30 kilograms per square meter. Calculations can reach 75,000 jin 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 greenhouse for growing mushrooms, enough for Chen Xin to eat by himself, 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 the more people, the more food they need, and the greenhouse area required will also be larger.

After all, at first glance, one would think that one hundred square meters can produce more than 70,000 catties of food a year, but the permanent population of this city is 300,000, thanks to the Yan Guo government’s policy of "not abandoning one person" before the disaster. At least 90% of people survived entering the shelter.

　　According to the calculation 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 consumption.

　　Because the ground can no longer grow any crops, 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 is nothing. Excluding the area of ​​rural arable land, just the labor reform farm near the city has 36,500 mu 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 sufficient 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 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 faced by major shelters.

　　 Fortunately, the end of the world has just begun, and all major refuges have sufficient material reserves, which can still be supported for a relatively long time.

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

　　 So it is foreseeable that food will become the most urgent rigid demand in the future, and to ensure that one can obtain a stable food supply, UU reading www.uukanshu.com has become the top priority for survival in this end time.

　　 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 time.

　　 Fortunately, for Chen Xin, with systematic help, food is no longer a problem for him.

"Okay, with Alan's help, the problem with you, Dragon Mother, is solved." Chen Xin looked at Mo Qingyan and said to her with a smile: "Then all you need to do next is Empty the wine cellar and transform 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 change it with a good one!" Mo Qingyan snorted at Chen Xin.

　　 Looking at Mo Qingyan's appearance, Chen Xin suddenly laughed: "Don't worry, you won't be disappointed!"

Regarding the bickering conversation between Chen Xin and Mo Qingyan, Qin Lan just watched from the sidelines, and when the two of them finished speaking, she said: "If the two of you have finished talking, should you go get A Xin? Did our SWAT team have food?"

　　 Although Chen Xin exchanged supplies with Uncle Ding in the name of Mo Qingyan, neither Uncle Ding nor Chen Xin understood that the parties involved in the transaction were Chen Xin and the SWAT team.

After all, even though Uncle Ding is the captain of the SWAT team, he can't take out so many supplies himself, and he can't eat so many vegetables by himself, so he collects the materials in the name of the SWAT team and exchanges the vegetables for the SWAT team It is inevitable for the team to improve the food.

　　 So Qin Lan has no problem saying that.

　　 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."
