Chapter 252

In the power distribution room of the shelter, the second uncle and several elders stood at the door, looking forward to Chen Xin directing two young electricians to connect the isotope thermoelectric battery he removed from the car to the circuit of the shelter.

"Well, just connect the red line and the blue line. With the power generation and service life of this battery, it can supply the whole shelter for more than ten years." Chen Xin watched two distant relatives connect the battery to the transformer of the power distribution box of the shelter with the circuit connecting cable, and then nodded to their second uncle for sure.

"Can this really meet the electricity demand? Just a little bit of battery? " An elder obviously couldn't believe it. After all, the isotope thermoelectric battery Chen Xin brought to us is too inconspicuous.

It's beyond the imagination of the elders who have been farming all their lives to supply such a large shelter with a thing as big as a hot water bottle.

Chen Xin's father was more receptive and asked Chen Xin, "what's the output power of this battery? How high is the voltage? "

"500V voltage, 150KW output power, this is for my car battery, to meet the needs of the shelter is no big problem." Facing his father's question, Chen Xin answered seriously: "the voltage is a little high. You must connect the transformer to use it, and it is dangerous. You need to pay special attention when using it. But it's not a big problem. After that, I will upgrade and optimize the circuit and adjust the access mode. There won't be any problem. "

Hearing Chen Xin say so, Chen Xin's father calculated it, and then said to his second uncle: "the power is a little low, but it's enough to meet the heating, that is, when other high-power electrical appliances are used, we should pay attention to the possibility of power shortage."

"It's good to turn on the heating, and there are other high-power appliances in the village." Second uncle heard Chen Xin's father say so, immediately a pair of happy appearance, did not care about Chen Xin's father said can't open more high-power electrical problems.

However, Chen Xin also heard his father's words, thought about it and said, "this is not a problem. I made this battery by myself. I can change it with a car battery. If you go back to my second uncle and change two car batteries in town, I can change a battery pack. In this way, there will be no problem, and the production capacity of the greenhouse can be expanded by one Point out

This is also what Chen Xin plans to do. Like his own refuge, he will increase greenhouse production capacity and obtain more output in exchange for more materials, forming a virtuous circle.

"Can greenhouses increase capacity?" Second uncle is particularly concerned about this. As the head of the village for many years and a farmer who has cultivated land all his life, he is most sensitive to the output of crops.

Chen Xin nodded his head and replied in the affirmative: "yes, after the electricity comes up, the fill light and heater in the greenhouse can work longer, so as to speed up the growth of crops and obtain higher yield. And I'm going to transform the structure of the greenhouse so that you can grow more food here. "

Chen Xin's words immediately made the elders present happy. For them, it is more practical than anything to be able to grow more food.

"That's a good feeling. It's a good thing to grow more food! If you have grain in your hand, you will not panic. " The second uncle's face was red with joy, which was quite different from the way Chen Xin had seen him for the first time when he came back.

Chen Xin didn't make any promises either. He just nodded and didn't say much. He just had an idea about the transformation of the greenhouse. He had to see how to do it first.

Now, second uncle, they can't wait to turn on the heating in the shelter.

With the heating on, the temperature in the shelter finally rose, and all the faces were smiling.

Chen Xin also received the system prompt for a long time:

"help others to improve their living conditions and get 5000 survival points"

"help 4 people to improve their living conditions and get 50 survival points every day"

of course, there are more than 50 people in the village, but only so many survival points can be gained by a single refuge to improve their living conditions.

For Chen Xin now, these gains are gratifying, but they don't make him pay special attention. What's more important is that this way can bring him income.

Thinking that he has provided isotope thermoelectric batteries to the state, Chen Xin can't help but look forward to how much survival it will bring if the state promotes this technology.

Even if a shelter has only 50 points, it is an astronomical amount of income under the large base of so many shelters in the country.

Now the only thing that worries Chen Xin is whether the isotope thermoelectric battery produced by others under his own influence can be recognized by the system, thus bringing him the income 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.

As long as the country starts to promote this kind of thing, it will inevitably become a hard currency. It will not worry about the sales volume. The impact on Chen Xin is nothing more than the survival of the final harvest.And as Chen Xin can provide more products, he will be able to harvest more survival. After all, although the harvest of survival can only be harvested once, there are too many places that can be improved in a refuge. He can cut one crop after another just like cutting leeks.

The greenhouse of this shelter in the village is quite different from that of Chen Xin. Although it is also a greenhouse, the area here is obviously much larger.

Moreover, Chen Xin can see that the greenhouse should have been transformed after adding a cover to the original farmland, instead of transporting the soil from the outside to the shelter as farmland.

But even so, the area of cultivated land is limited. According to the second uncle's introduction, the area of cultivated land here is only about one and a half mu, a total of 900 square meters.

The 900 square meters of land is like a huge nine palace grid. In the center of the greenhouse, there are four thick supporting columns, and there are twelve similar supporting columns beside the wall to support the top span beam.

Nine hundred square meters of farmland sounds like a lot of land, and the output is fairly good. But considering that there are more than 100 people in the village, the output is not much. After all, this greenhouse is not like Chen Xin's, which can turn on lights and heaters 24 hours a day.

The greenhouse with only one layer of soil is not like the multi-layer greenhouse upgraded by Chen Xin, which can realize three-dimensional planting and obtain greater yield.

The crops planted in the field are also relatively single, with only cabbage, radish and a large area of leafy crops unknown to Chen Xin.

"Second uncle, what kind of plant is this?" Chen Xin went to the edge of the leaf crop and looked at the vines and leaves growing almost close to the ground. He asked his second uncle curiously.

"It's sweet potato. It's been planted for almost four months. It's almost ready to harvest." Referring to these crops, the second uncle's face was full of pride and satisfaction. As he said, he had grain in his hand, but he didn't panic.

For farmers in Yanguo, these crops with good harvest are the biggest source of happiness.

When Chen Xin heard his second uncle say that this kind of sweet potato is sweet potato, he immediately showed a surprised expression: "is this sweet potato?"

"Well? Ah Xin, haven't you seen sweet potatoes? " Second uncle some doubts, sweet potato this kind of thing should be very common, Chen Xin should not have seen it.

Chen Xin shook his head, reached out and touched the vines and leaves of these sweet potatoes, and said, "of course I've seen sweet potatoes, but I really haven't seen the vines and leaves growing in the ground."

Hearing Chen Xin say so, the second uncle nodded his head with understanding. It's true that many people have eaten sweet potato, but not everyone knows sweet potato vine and sweet potato leaf.

"Do you have a greenhouse yourself? Do you want to bring some sweet potatoes back? This kind of thing is very good. A sweet potato can be used as a seed after it is chopped up. " The second uncle thought that Chen Xin also had a greenhouse, and immediately proposed to him.

Chen Xin heard the second uncle said so, but he didn't refuse. He stood up and said, "I'll trouble the second uncle. Although I have a lot of seeds, I really don't have sweet potatoes."

"It's a small thing, but what kind of staple food do you grow there? You can't just grow vegetables. It's not enough to eat vegetables. " The second uncle is worried about Chen Xin. Obviously, in his opinion, the staple food should be planted in any way.

Chen Xin didn't have any questions about this. He replied with a smile: "I grow upland rice, which is more than enough for me to eat. In addition, there are many vegetables, so I can get a lot of food. After all, my place is a city, and the food is much better than my home. "

When the second uncle heard Chen Xin say this, he nodded and asked him, "ah Xin, I'm relieved if you say that. Then you can see what can be transformed in this greenhouse. It's good to increase the output more, so that the villagers can have enough to eat."

This is also the second uncle's most concern and expectation. Most of the greenhouses in front of him are planted with sweet potatoes, and the growth of sweet potatoes takes at least five to seven months. Even short-lived sweet potatoes take four months. Before harvest, the villagers can't talk about how full they are.

"I'll have a look first. I just have an idea about how to transform it. I'll see more about it." Chen Xin didn't make sure, and asked his second uncle for his request: "second uncle, what do you think greenhouse should do? My idea is to add a hydroponic layer so that we can grow a lot of crops. "

Hearing Chen Xin say so, second uncle can't help but worry: "hydroponic cultivation? Is it easy to do? I've heard of this technology, but no one in the village has done it! "

"This technology is not complicated. Second uncle, listen to me..." Chen Xin laughed and introduced hydroponic cultivation techniques to his second uncle.
