Doomsday Bunker Upgrade Chapter 37: To sell vegetables

Supplementing fresh water and expanding the capacity of the water tank is a relief for Chen Xin, which relieves his urgent needs.

　　 With a pump that can pump groundwater, Chen Xin obviously doesn't need to use water tightly as before.

　　 Although there were three tons of fresh water before, there is a water circulation system that can purify sewage and recover water vapor in the air, but the refuge is not a space station in space, it cannot be completely sealed, and the efficiency of the water cycle is naturally not 100%. , In fact, it is already a remarkable efficiency to achieve a water cycle efficiency of 90%.

　　 But even so, with a loss of 10% in one cycle, three tons of water will not last long. According to the statistics of urban residents in Yan Country, under normal circumstances, a person will consume 130-300 liters of water a day, on average. A month is about 4 to 10 tons of water.

　　 And this has not yet calculated the water consumption of the planting greenhouse.

　　 Including the evaporation of water vapor from the ventilation pipes and the water consumption of the planting greenhouse, Chen Xin was able to persist for a month before the water shortage problem occurred. It is really that he has already saved water very much.

　　 But now with a water pump and a large water tank that can hold eight tons of water, Chen Xin can more or less loosen the water. You don’t need to be like an astronaut on a space station like before. Washing his face every day is to wipe it with a wet towel. Once you take a bath, you can only rub soap after you get wet, and you have to turn off the faucet when you rinse it off.

　　 can relax some water restrictions, which is really a great improvement in living conditions for Chen Xin.

　　 He believes that when the survival point is settled tonight, he can at least increase his daily income by at least 1 point.

After filling the water tank, Chen Xin turned off the water pump, and then returned to the planting greenhouse to continue watering, re-watering the previously unwatered fields.

If an acre of land is used to grow vegetables, it is really just a small vegetable garden. There is not much space, but in fact, 100 square meters is not small at all.

　　 If you put it in a place like Beijing, Shanghai, Guangzhou, and a 100-square-meter house, you won’t be able to get it without a base of one or two million. Do you still think this one-hundred-square-meter is small?

　　 And 100 square meters of land for growing upland rice may only be enough for Chen Xin to eat alone, but if you grow cabbage and lettuce, vegetables that can be harvested in one month, the yield is considerable.

　　 At least after Chen Xin had harvested the ripe lettuce and cabbage in the field, he found that there was already a pile of piles on the ground, making Chen Xin feel that he could not finish eating it.

　　 How many of these vegetables are there, Chen Xin doesn’t have a scale, so it’s obviously impossible to keep statistics.

But there are at least one or two hundred vegetables, and there are still several vegetables left to be planted, and carrots planted on the other half of the land.

　　 Calculated by eating one vegetable a day, these vegetables are old enough to eat for more than half a year.

Even if the cabbage is durable and Chen Xin eats cabbage every day, he doesn't think he can eat the cabbage in half a year, not to mention the same amount of lettuce next to him.

　　 So I left a portion that I could eat, and Chen Xin planned to use it out to exchange supplies.

And this is also Chen Xin's original plan. No matter what the outside world is like, Chen Xin needs to go out and see what the world has become under the impact of the meteorite.

　　After packing the harvested vegetables in the large plastic boxes they found, Chen Xin thought about what to do with these vegetables.

　　 These boxes are the storage boxes I bought before. They were originally used to put things in the shelter, but after actually entering the shelter, Chen Xin found that there was nothing to be packed in boxes, and these storage boxes were also It has been shelved in the storage room, but now it comes in handy.

　　 In the process of packing these lettuce and cabbage, Chen Xin also roughly estimated how many vegetables there are.

　　 There are about 80 pieces of cabbage, each packed in two plastic boxes, which looks at least three to four hundred kilograms. Although the lettuce production on the side is not as exaggerated as cabbage, it is also filled with one and a half plastic boxes. About two hundred pounds.

　　Chen Xinzhong’s cabbage is an early-maturing variety. Because the plant is grown in a greenhouse, although it has only been planted for a month, it grows very full. According to Chen Xin’s estimation, one piece is enough for him to eat three. It's been five days.

　　 Fortunately, cabbage itself is a storage-resistant vegetable. As long as it is stored properly in a low temperature environment, it can be stored for three or four months without damage.

　　 So Chen Xin left a box of cabbage and half a box of lettuce in his storage room, while the remaining two boxes of vegetables were moved to the garage, ready to be exchanged for supplies.

　　 Just when he moved the cabbage and lettuce to the storage room, Chen Xin looked at his storage room and scratched his head, thinking that he should include the upgrade of the storage room in the upgrade plan.

　　 When the storage room was being repaired, because all bottled water and self-heating food in bags were stored, there was no need for low-temperature storage to keep fresh, so Chen Xin didn’t use these functions and didn’t prepare them in the refuge. refrigerator.

　　 But now that these fresh vegetables are harvested, Chen Xin has to consider the storage of vegetables.

The cabbage is not a big problem, the temperature in the storage room is not high ~IndoMTL.com~ should be able to store for a long time, but if the lettuce is stored for a few days, it may wilt.

　　 Therefore, creating a freezer or refrigerator that can store at least one or two hundred catties of vegetables is what Chen Xin needs to worry about now.

　　 Someone may ask, doesn’t it mean that the outside temperature will drop to tens of degrees below zero? Are you worried that the vegetables will go bad at such a low temperature? Shouldn't you be worried that it's hard to bite?

　　 is indeed saying that, but the problem is that the temperature has not dropped so low yet!

　　 Moreover, Chen Xin’s storage room is in the refuge, which is located under the 100-meter-thick soil layer above the head like the refuge. It is impossible to be as low as tens of degrees below zero like the outside world! If that's the case, Chen Xin would have frozen hard long ago.

The soil layer has a thermal insulation effect, and although the underground geothermal heat is not obvious on the surface, in fact, the heat is continuously transmitted from the mantle to the surface.

In fact, scientists have calculated that the temperature will rise by 25 degrees for every kilometer of underground depth. On average, for every 100 meters of formation depth, the temperature will rise by three degrees.

So now Chen Xin's shelter is actually not very cold. The temperature in the container house is still more than 20 degrees. It may not be able to wear a single coat, but a jacket is almost enough.

　　Of course, this temperature cannot be considered hot. These vegetables may not deteriorate quickly when stored in the storage room, but even if the temperature in the storage room is not high, it is still ten degrees Celsius. If Chen Xin wants to pick these Save the harvested fresh vegetables to eat slowly, so it is necessary to prepare a refrigerator or freezer.

Fortunately, it is the end of the world now. If you want to take these fresh vegetables out, it should be no problem to change to a refrigerator or freezer, and maybe you can change a lot of other materials.

　　 Thinking of this, Chen Xin began to prepare for going out.
