The fresh water was replenished and the capacity of the water tank was expanded. This was a timely help for Chen Xin and solved his urgent need.
With a water pump that can extract groundwater, Chen Xin obviously doesn't have to be as tight with water as before.
Although there were three tons of fresh water and a water circulation system that could purify sewage and recycle water vapor in the air, the shelter was not a space station in space. It could not be completely sealed, and the water circulation efficiency was naturally not 100%. In fact, the shelter was not a space station in space. Being able to achieve a water circulation efficiency of 90% is already a very impressive efficiency.
But even so, with a 10% loss in one cycle, three tons of water will not last long. According to Yanguo's urban residents' water consumption statistics, under normal circumstances, a person will use 130-300 liters of water a day, which is about the same in a month. That’s 4 to 10 tons of water.
And this does not include the consumption of watering the greenhouse.
Taking into account the evaporation of water vapor in the ventilation ducts and the watering consumption of the planting greenhouse, Chen Xin was able to persist for a month before experiencing water shortage. It is true that he has saved water very much.
But now that he has a water pump and a large water tank that can hold eight tons of water, Chen Xin can be more relaxed about using water. He doesn't have to live like an astronaut on the space station like before. He just wipes his face with a wet towel and takes a shower every day. You can only wet your body and then rub soap, and then turn off the faucet after rinsing.
Being able to relax some water restrictions is really a great improvement in living conditions for Chen Xin.
He believed that when the survival points were settled tonight, he could 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 greenhouse to continue watering, re-watering the ground that had not been watered before.
If one acre of land is used to grow vegetables, it is really just a small vegetable garden, not much space, but in fact, one hundred square meters is not small at all.
If you put it in places like Beijing, Shanghai and Guangzhou, you can't buy a house of 100 square meters without a minimum of one or two million. Do you still think that 100 square meters is small
Moreover, a hundred square meters of land to grow upland rice may only be enough for Chen Xin alone, but if you grow vegetables such as cabbage and lettuce that can be harvested in a month, the yield will be considerable.
At least when Chen Xin picked all the mature lettuce and cabbage from the ground, he found that there was already a big pile on the ground, which made Chen Xin feel like he couldn't finish them all.
Chen Xin didn't have a scale, so he obviously couldn't count how many vegetables there were.
But there were at least one or two hundred vegetables, and that still didn't include the few vegetables left for planting and the carrots planted on the other half of the land.
Based on the calculation of eating one vegetable a day, these vegetables are enough for Chen Xin to eat for more than half a year.
Even if cabbage is shelf-stable and Chen Xin eats cabbage every day, he doesn't think he can finish it in half a year, not to mention the same amount of lettuce next to it.
So he kept enough for himself, and Chen Xin planned to exchange the rest for supplies.
And this was Chen Xin's original plan. No matter what the situation was like outside, Chen Xin needed to go out and see what the world had become after the meteorite impact.
After packing the harvested vegetables in the large plastic boxes he found, Chen Xin thought about what to do with the vegetables.
These boxes are storage boxes that he bought before. They were originally used to store things in the shelter. However, after entering the shelter, Chen Xin found that there was nothing that needed to be packed in boxes, so these storage boxes have been put on hold. In the storage room, it comes in handy now.
In the process of packing the lettuce and cabbage into boxes, Chen Xin also roughly estimated how many vegetables there were.
There were about eighty cabbages, each packed in two plastic boxes, which seemed to weigh at least three to four hundred kilograms. The lettuce on the side, although not as exaggerated as the cabbage, was still full of one and a half plastic boxes, weighing about two tons. It weighs over a hundred kilograms.
The cabbage planted by Chen Xin is an early-maturing variety. Because the plants are grown in a greenhouse, although they have only been planted for a month, they have grown very plump. According to Chen Xin's estimation, one plant is enough for him to eat for three to five days. .
Fortunately, cabbage itself is a shelf-stable vegetable. As long as it is stored properly in a low-temperature environment, it can be stored for three to four months without going bad.
So Chen Xin left a box of cabbage and half a box of lettuce and put them in his storage room, while the remaining two boxes of vegetables were moved to the garage, ready to be exchanged for supplies.
Just when moving cabbage and lettuce into the storage room, Chen Xin looked at his storage room and scratched his head, feeling that he should also include the upgrade of the storage room in the list of upgrade plans.
When the storage room was built, because all the items stored were bottled water and bagged self-heating food, there was no need for low-temperature storage and preservation. Chen Xin did not install these functions, let alone prepare a refrigerator in the shelter.
But now that these fresh vegetables have been 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, so it should be able to be stored for a long time, but the lettuce may become wilted within a few days.
So finding a freezer or refrigerator that can store at least one or two hundred kilograms of vegetables has become what Chen Xin needs to worry about now.
Some people may ask, isn't it said that the outside temperature will drop to dozens of degrees below zero? Are you worried about vegetables spoiling at such a low temperature? Shouldn't we worry that it's too frozen to bite
That’s true, but the problem is that the temperature hasn’t dropped so low yet!
Moreover, Chen Xin's storage room is inside the shelter. Like the shelter, it is located under the hundreds of meters of soil above the head. There is no way it can be dozens of degrees below zero like the outside world! If that were the case, Chen Xin would have been frozen to death.
The soil layer has a thermal insulation effect, and although the geothermal heat underground is not obvious on the surface, the heat is actually constantly being transmitted from the mantle to the surface.
In fact, scientists have calculated that for every one kilometer of underground depth, the temperature will rise by 25 degrees. On average, for every one hundred meters of underground depth, the temperature will rise by three degrees.
So it's actually not that cold in Chen Xin's shelter now. The temperature in the container house is still over 20 degrees. It may not be enough to wear a single coat, but a coat will be enough.
Of course, this temperature cannot be considered hot. These vegetables may not spoil quickly if stored in the storage room, but even if the temperature in the storage room is not high, it is still more than ten degrees. If Chen Xin wants to harvest these vegetables, If you want to save fresh vegetables and eat them slowly, it is necessary to prepare a refrigerator or freezer.
Fortunately, it's the end of the world now. If you take these fresh vegetables out, it should be no problem to exchange them for a refrigerator or a freezer, and maybe a lot of other supplies.
Thinking of this, Chen Xin began to prepare for going out. (End of chapter)
