Chapter 162: Sealed refuge

Pushing open the heavy protective door that was originally closed, the small shelter in front of him was opened again.
Standing at the door, Chen Xin could still see some debris scattered on the ground, which was obviously left over from the previous evacuation.
"It looks like it needs to be cleaned up." Although they haven't entered yet, the first impression of this small shelter for Chen Xin and Li Yulong is that it is a bit dirty.
"After the people who originally lived here were evacuated due to oxygen supply problems, this refuge was temporarily sealed." The staff sent by the city government heard Chen Xin's comments and didn't feel anything wrong, but just ordered. Nodding his head to introduce the situation here: "This refuge was originally an underground parking lot, with upper and lower floors of 2,000 square meters each. Because only the second underground floor meets the civil air defense standards, only this floor was transformed into a refuge, designed to accommodate A thousand people."
"A thousand people? It sounds big!" Li Yulong listened to the introduction of the city government staff, and asked Chen Xin as he walked in: "Brother Xiao Chen, do you think we can use such a large space? ?"
Regarding this question, Chen Xin just shook his head and replied: "Not enough. Two thousand square meters is only more than three acres. If you plant a plantation, it is okay to grow vegetables and fruits, but rice is not enough for the workers."
"The consumption is not that big, right?" Li Yulong frowned upon hearing Chen Xin's words. He felt that 2,000 square meters sounded quite big, and he didn't understand why Chen Xin didn't say enough.
"The planting greenhouse in my refuge is 200 square meters, calculated on a per mu yield of 1,200 catties. If you grow rice, you can harvest 1,200 catties in three seasons a year. Three people can eat too much, and four people can’t eat enough. You still think Is this place big?"
"Ah? No? The two thousand square meters of land, the food grown is not enough for fifty people? Doesn't our country have super rice? What is the output?" Li Yulong seemed to be poured cold water, suddenly Feeling discouraged.
However, Chen Xin smiled and said: "Super rice can indeed yield 2,000 catties per mu, but it is very dependent on seeds and fertilizers. The seeds must be replaced one year after planting, otherwise the degradation will be very severe. Even if you can find someone to give it to you. If you breed, the operating cost will be very high, so if you build a greenhouse just to grow rice, it will just waste time and energy."
Although Chen Xin said this with a smile, the people who came down with them all heard the mockery in his words.
Because this matter also cooperates with the SWAT team, there is a team of SWAT police stationed here, in addition to daily patrol tasks, to maintain law and order here.
Chen Xin was a little selfish and convinced that the team sent by Uncle Ding was Qin Lan's team, so Qin Lan came here with them today to check the situation here and make some preparations for the subsequent stationing of the special police team.
But when Chen Xin said this, Qin Lan frowned and asked, "But you have to plant food! If you don't grow food because of a crop shortage, wouldn't everyone starve to death?"
"That's right, but Xiaolong is engaged in plantation, of course, to obtain economic value first." Faced with Qin Lan's question, Chen Xinchong gave her a soothing look before continuing to explain: "Of course, this is all. It is based on the premise of only planting one crop. In the current environment and existing planting conditions, the three-dimensional planting should be used, and the use of space is as far as possible to expand the planting area.
In this way, the usable planting area and the types of crops that can be grown have been greatly increased. If the fish and vegetable symbiosis system is used, it can also provide aquatic products, and the yield will be more assured. "
"Three-dimensional planting, fish and vegetable symbiosis? How do you do this?" Li Yulong immediately became excited again when he heard Chen Xin's words, as if he was not the one who was frustrated just now.
"It's very simple. Dig deep into the ground to make a pond for fish farming. Cover the surface with planting plates to grow rice, and then set up several layers of hydroponics to grow vegetables and fruits." Chen Xin briefly explained a few words and looked at the empty refuge. So, I asked Li Yulong: "Xiaolong, have you figured out how to plan this place? Can't all two thousand square meters be used for farming?"
"It's not impossible to use all the land for farming, right?" Li Yulong joked, but quickly said with a serious face: "I plan to allocate two-thirds of the area for planting, and the remaining one-third of the area will be transformed. As a residential area."
"That place will be a bit crowded!" Chen Xin heard his arrangement and already understood his plan. He smiled and said nothing more, but followed the city staff to check the shelter. Happening.
Although this is only a small refuge, it was built according to standards at the beginning, and all facilities are complete.
Chen Xin followed the staff of the city government for a round tour and was very satisfied to see that the water and electricity facilities were still operating normally.
After introducing the internal situation of the shelter, the staff member talked about other supporting facilities:
After the disaster ~EbookFREE.me~ the upper floor of this shelter was remodeled, but only half of it was used. It is used by coal-fired stacks. Because the refuge uses boilers for heating, and the boilers are installed on the upper floor, coal is also piled on the upper floor."
"Can this boiler be removed? We installed a ground-source heat pump. There is no need to keep the boiler." Li Yulong heard Chen Xin and the city staff talk about heating equipment, and suddenly did not want the old-fashioned coal-fired boiler.
However, Chen Xin shook his head and said, "Keep it there. In case of any situation, when the ground source heat pump fails, there is a second emergency plan. Besides, the equipment cannot be turned forever, it will always be shut down. Overhauled."
"Then I listen to Brother Xiao Chen, but half of the area upstairs is a waste of stacks, right?" Li Yulong nodded in agreement with Chen Xin's opinion, and asked his own doubts: "Brother Xiao Chen, do you have any questions about this? What is the arrangement?"
Faced with Li Yulong’s question, Chen Xin just smiled and patted his shoulder:
Why ask me if you have an idea? The boss is you, do what you want.

After speaking, Chen Xin walked towards Qin Lan, and the two got together in an intimate manner, as if they were saying something private.
Li Yulong watched Chen Xin and Qin Lan walk over and talked about them, and shrugged his shoulders indifferently, and continued to say with the staff of the city government: "In this case, the boiler will not be demolished. Can it be supplied?"
"This is okay, but the city government will not provide it for free." Although the city government staff are a little confused about Chen Xin and Li Yulong, he is not sloppy about his own job. He heard Li Yulong. Speaking of the supply of coal, I immediately discussed the price with him.
