Chapter 251: Sweet potatoes and greenhouse

"I can upgrade the refuge novel ( to find the latest chapter!
In the power distribution room of the refuge, the second uncle and several elders stood at the door, looking forward to seeing Chen Xin commanding two young electricians to connect his isotope temperature difference battery removed from the car into the refuge Circuit.
"Well, as long as the red and blue wires are connected, the power generation and service life of this battery are enough to supply the entire shelter for more than ten years." Chen Xin watched two distant relatives connect the battery with a circuit connection cable. After receiving the transformer on the distribution box of the refuge, he nodded affirmatively to the second uncle and the others.
"This can really meet the electricity requirements? Just such a small piece of battery?" An elder obviously couldn't believe it, after all, the isotope temperature difference battery that Chen Xin brought was too inconspicuous.
Only something as big as a larger thermos can satisfy the power supply of such a large refuge, which is beyond the imagination of these elders who only cultivated the land for their entire lives.
However, Chen Xin's father was more able to accept this, and asked Chen Xin: "What is the output power of this battery? How high is the voltage?"
"The voltage of 500V and the output power of 150KW. This is the battery for my car. There is no big problem in meeting the needs of the shelter." Faced with his father's question, Chen Xin answered seriously: "The voltage is a bit high. , It must be connected to the transformer before it can be used, and there is a certain degree of danger, so you need to pay special attention when using it. However, it is not a big problem. Later, I will upgrade and optimize the circuit and adjust the connection method. There will be no problem ."
Hearing what Chen Xin said, Chen Xin’s father calculated it, and then said to his second uncle:
The power is a bit low, but it’s enough to meet the heating requirements. Be careful when using other high-power electrical appliances. There may be insufficient power. ."
"It's good to be able to turn on the heating, and there are no other high-power electrical appliances in the village." When the second uncle heard Chen Xin's father say this, he was immediately happy, and didn't care about Chen Xin's father. Can not open more high-power electrical appliances.
However, Chen Xin also heard what his father said, and he thought about it and said, "This is not a problem. I made this battery by myself. I can change one with a car battery. If you look back at the second uncle, you can get two cars in town. When the battery comes, I can change a battery pack, so there is no problem, and the production capacity of the greenhouse can be expanded a bit."
This is also something in Chen Xin's plan. Like his own refuge, he will increase greenhouse production capacity and obtain more output in exchange for more materials and form a virtuous circle.
"Can greenhouses increase production capacity?" The second uncle is particularly concerned about this. As the village head of the village for many years, he is also a farmer who has been planting land for a lifetime. He is most sensitive to the issue of crop output.
Chen Xin nodded and replied affirmatively: "Yes, after the power is up, the fill light and heater in the greenhouse can work for a longer time, thereby speeding up the growth of crops and obtaining higher yields. And I plan to Transform the structure of the greenhouse, and strive to provide you with a variety of food here."
Chen Xin's remarks immediately made the elders present happy. For them, being able to have a variety of food is more real than anything else.
"That feeling is good, it's a good thing to be able to have more food! With food in hand, I don't panic." The second uncle's face was red with joy, and it was completely full of face when Chen Xin came back and saw him for the first time. different.
Chen Xin didn't make any package tickets either, he just nodded and didn't say much. He just had an idea about the renovation of the greenhouse, and he had to read it before talking about it.
As for now, the second uncle and the others can't wait to turn on the heating system in the shelter.
With the activation of the heating equipment, the temperature in the refuge finally rose, and smiles appeared on everyone's faces.
As for Chen Xin, he also received a system prompt after a long absence:
"Help others improve their living conditions in refuges and get 5000 survival points"
"Help 4 people improve their living conditions and get +50 survival points every day"
The population of the village is of course more than 50 people, but a single refuge can only increase survival points by improving living conditions at a time.
As far as Chen Xin is concerned, these gains are gratifying, but he is no longer particularly concerned about it. More importantly, this method can bring him income.
Thinking of providing the country with isotope temperature difference batteries, Chen Xin can't help but look forward to it. If the country promotes this technology, it can bring him much survival.
Even if a shelter has only 50 points, with the large base of so many shelters in the country, this is an astronomical income.
The only thing Chen Xin worries about now is whether the isotope thermoelectric battery produced by others under his own influence can be recognized by the system, thus bringing himself a point of survival.
Chen Xin is not sure about this problem, but the problem is not big. Even if the isotope thermoelectric battery produced by others is not recognized by the system, he can produce it himself and sell it to others.
This kind of just-needed thing will inevitably become a hard currency as long as the country starts to promote it. There will be no sales problem at all. The impact it can have on Chen Xin is nothing but a question of the survival point of the final harvest.
And as Chen Xin can provide more products, he can gain more survival points. After all, although the harvest of survival points can only be harvested once, there are too many places that a refuge can be improved. He can cut stubble after stubble just like cutting leeks.

The greenhouse in this refuge in the village is completely different from Chenxin's greenhouse. Although it is also a greenhouse, the area here is obviously much larger.
Moreover, Chen Xin could see that this greenhouse should have been transformed after adding a cover to the original farmland, instead of transporting soil into the refuge from the outside to use it as farmland, as he did before.
But even so, the area of ​​arable land is limited. According to the second uncle's introduction, the area of ​​arable land here is only about one and a half acres, a total of 900 square meters.
The 900 square meters of land is like a huge nine-square grid. In the center of the greenhouse are four thick supporting pillars, and twelve of the same supporting pillars along the wall support the top span.
The nine hundred square meters of farmland sounds not small, and the output is not bad, but considering that there are more than one hundred people in the village, the output is not that much. After all, this planting greenhouse is not like Chen Xin’s own. The lights and heaters can be turned on for 24 hours.
The greenhouse with only one layer of soil is not like the multi-layered greenhouse upgraded by Chen Xin, which can realize three-dimensional planting and obtain greater output.
The types of crops planted in the ground are also relatively single, only cabbage, radish, and a large leaf crop that is unknown to the old.
"Second uncle, what is this planted?" Chen Xin walked to the side of the leaf crops, looked at the vines and leaves that were almost all growing against the ground, and curiously asked the second uncle.
"This is a sweet potato. It has been planted for almost four months, and it is almost ready for harvest." When it comes to these crops, the second uncle's face is also full of pride and satisfaction. As he said, there is grain in his hand. Don't panic.
For farmers in Yan Country, these harvestable crops are the greatest source of happiness.
When Chen Xin heard the second uncle say that this kind of sweet potato is sweet potato, he suddenly showed a surprised expression: "Is this the sweet potato?"
"Huh? Axin, haven't you seen sweet potatoes?" The second uncle was a little confused. Sweet potatoes should be very common, and it should be impossible for Chen Xin to have never seen it.
Chen Xin shook his head and reached out to touch the vines and leaves of these sweet potatoes and said, "Of course I have seen sweet potatoes, but I have never seen sweet potato vines and sweet potato leaves that grow in the ground."
Hearing what Chen Xin said, the second uncle also nodded in understanding. It is true that many people have eaten sweet potatoes, but sweet potato vines and sweet potato leaves are indeed not known to everyone.
"You also have a greenhouse? Would you like to bring you some sweet potatoes, this kind of thing is very easy to grow, a sweet potato can be used as a seed if you chop it up." The second uncle thought that Chen Xin also has a greenhouse, and immediately suggested to him. .
Chen Xin heard the second uncle say so, and did not refuse, stood up and said, "Then trouble the second uncle. Although I have a lot of seeds, there is really no sweet potato."
"It's a trivial matter, but what kind of staple food do you grow there? You can't just grow vegetables. Just eating vegetables will not fill your stomach." The second uncle expressed concern to Chen Xin. Obviously, in his opinion, all the staple foods are To be planted.
Chen Xin had no problem with this, and smiled and replied: "I grow upland rice, but it is more than enough for me to eat by myself. With a lot of vegetables, I can get a lot of food. After all, my place is a city. In terms of food, it’s much better than at home."
Hearing Chen Xin's words, the second uncle nodded, and then asked him: "Axin, if you say that, I can rest assured~EbookFREE.me~ Then you can see what can be transformed in this greenhouse. Locally, it is a good thing to increase production more so that people in the village can eat a little bit more."
This is also what the second uncle is most concerned about and looking forward to. Most of the greenhouse in front of us is planted with sweet potatoes, and it takes at least five to seven months for the growth of sweet potatoes. Even the short-lived sweet potatoes take four months, before harvesting. People in the village can't talk about how full they are.
"Let’s take a look first. I just have an idea about how to remodel it. I still have to read it before." Chen Xin did not pack the ticket, and asked his second uncle about his requirements: "Second uncle, do you think the greenhouse should How to do it? My idea is to add a layer of hydroponic planting so that a lot of crops can be grown."
Hearing what Chen Xin said, the second uncle couldn't help being a little worried: "Hydroponic planting? Is this something good? I have heard of this technique, but no one in the village has done it!"
"This technique is not complicated, your second uncle, listen to me..." Chen Xin laughed and introduced the second uncle's hydroponic planting technology.
