In fact, Mo Qingyan also knows how important it is to have a greenhouse that can produce food in an apocalyptic environment. However, her family's shelter was built when the house was originally built. The greenhouse was not considered at that time, and instead the underground The first floor is designed as a bar.
This also resulted in Mo Qingyan's shelter not being able to sustain food.
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 there is enough underground space, Mo Qingyan has a lot of supplies, enough to last her, Mo Qingxin and Ding Ning for two years.
If it were just a nuclear war or other doomsday disaster, one or two years would be enough time for them to wait for post-disaster reconstruction or rescue by search and rescue teams.
But now we have to face a hundred-year-long extremely cold night. The surface of the earth will be a frozen soil environment within a hundred years, which is not suitable for the cultivation of any crops. It can be said that almost 99% of human food production has been completely eliminated. .
Under such circumstances, all people can count on are the material reserves before the disaster and the underground greenhouses built in shelters that are less affected by the temperature.
Chen Xin may not know the situation because it is far away from the city, but Mo Qingyan knows something about the situation because it is close to the city government shelter and shopping mall shelter. Now the shelters in the city have begun Control the use of supplies.
Although the main source of food is still the grain stored before the disaster, the food has also begun to be mixed with mushrooms grown in greenhouses and rats raised.
In the Yan Kingdom, mushroom cultivation technology is quite mature, which is why the government chose to use mushrooms as the main source of food for post-disaster shelters.
Mushrooms are the main source of food available in the current environment. If managed properly and in a suitable environment, if a planting area of 100 square meters is planted with five layers of three-dimensional cultivation, the yield can be even the most conservative 30 kilograms per square meter. Calculated, it can also reach 75,000 kilograms per year.
This output is not low, but if they want to ensure the food supply of a shelter, although it is difficult to build a greenhouse in a small shelter, it is not a big problem for them to ensure food supply without a large planting area.
It's like Chen Xin's refuge, a 100-square-meter greenhouse. If all mushrooms were grown, it would be enough for Chen Xin to eat until he died, and there would still be excess production that could be used to make mushroom wine to drown himself.
But for large shelters, the problem is more serious, and the larger the shelter, the more severe the problem.
Because the more people there are, the more food is needed, and the greenhouse area required will also be larger.
After all, at first glance, one hundred square meters can produce more than 70,000 kilograms of food a year, which may seem like a lot. However, the city’s permanent population is 300,000. Thanks to the Yanguo government’s “never abandon a person” policy before the disaster, At least more than 90% of the people were able to enter the shelter and survived.
If one person consumes one ton of food per year, 270,000 people would need at least 360,000 square meters of mushroom cultivation area to meet their consumption.
Because no crops can be grown on the surface, all food sources are underground greenhouses, but there is obviously not such a large space in the shelter to arrange a greenhouse.
And 360,000 square meters is 3,600 acres, 540 acres, 36 hectares, which is equivalent to the area of half the Forbidden City, 1.7 Bird's Nests, and 51.4 standard football fields.
Such a large area, of course, would have been nothing if it was before the disaster. Not counting the area of rural cultivated land, just the labor reform farms near the city had 36,500 acres of cultivated land, so food output was not a problem at all.
As for building a planting greenhouse or something like that, if you wanted to build it on the ground before the disaster, such a large-area planting greenhouse was just a matter of money, and there would be no construction difficulties.
But in the apocalypse when disaster has struck, it is no longer possible to build greenhouses on the surface due to the severe cold. If you want to ensure sufficient food production, you can only dig enough space underground.
And it takes a long time to dig out such a large area of underground space.
Even if major shelters have enough manpower and may have stocked up on tools before the disaster, digging out such a large space is still a very large project.
In other words, if there are no other factors affecting the situation in the future, food shortage will be a problem that major shelters will inevitably face.
Fortunately, the end of the world has just begun, and all major shelters have sufficient material reserves, which can still last for a relatively long time.
This period is a prime time for each shelter. Whether they can cope with the food crisis that will arise depends on whether they can dig out enough greenhouses during this period.
Therefore, it is foreseeable that food will become the most urgent need in the future, and being able to ensure that you have access to stable food supplies has become the top priority if you want to survive in this apocalyptic world.
Whether it is Chen Xin, Mo Qingyan, or the people in other shelters, they must solve this problem first if they want to survive in this apocalypse.
Fortunately, for Chen Xin, with systematic help, food is no longer a problem for him.
"Okay, with A-Lan's help, now Long Niang, your problem has been solved." Chen Xin looked at Mo Qingyan and said to her with a smile in his tone: "Then all you need to do is The wine cellar was vacated and converted into a greenhouse.”
"Hmph, I vacated the wine cellar, so you can focus on my collection, right? I'm telling you, if you want my wine, give me something good in exchange!" Mo Qingyan snorted at Chen Xin.
Seeing Mo Qingyan's appearance, Chen Xin suddenly laughed: "Don't worry, I won't let you down!"
Regarding the bickering conversation between Chen Xin and Mo Qingyan, Qin Lan just watched from the sidelines. After the two of them finished talking, she said: "After you two have finished talking, shouldn't you go get the A-Xin you promised to give me?" Are we a loser to our SWAT team?"
Although Chen Xin used Mo Qingyan's name to exchange supplies with Uncle Ding, both Uncle Ding and Chen Xin understood that the two parties to the transaction were Chen Xin himself and the SWAT team.
After all, although Uncle Ding is the captain of the SWAT team, he cannot bring out so many supplies himself, and it is impossible for him to eat so many vegetables by himself, so he collects supplies in the name of the SWAT team and gives the vegetables in exchange to the SWAT team. It became inevitable for the team to improve their food.
So there is no problem at all when Qin Lan says this.
Facing Qin Lan's urging, Chen Xin laughed and led them to his greenhouse: "Don't worry, the vegetables are already mature. I was harvesting them before you came." (End of Chapter)
