Pushing open the heavy protective door that had been closed, the small shelter that had been closed in front of him opened the door again.

Standing at the door, Chen Xin could still see some debris scattered on the ground, apparently left over from the previous evacuation.

"Looks like it needs to be cleaned up." Although they haven't entered it yet, the first impression of this small shelter for Chen Xin and Li Yulong is that it is a little dirty.

"After the evacuation of the people who originally lived here due to oxygen supply problems, this shelter has been temporarily sealed." When the staff sent by the city government heard Chen Xin's evaluation, they didn't feel anything wrong, but just nodded and introduced the situation here: "This shelter was originally an underground parking lot, with two floors of 2,000 square meters each. Because only the second basement floor meets the civil air defense standards, only this one floor has been converted into a shelter and is designed to accommodate 1,000 people. ”

"A thousand? Sounds big! Li Yulong listened to the introduction of the city government staff, and while walking inside, he asked Chen Xin: "Brother Xiao Chen, do you think we can use such a big place?" ”

Regarding this question, Chen Xin just shook his head and replied: "It's not enough, 2,000 square meters is only more than three acres of land, if you build a plantation, it's okay to grow vegetables and fruits, and planting rice is not enough for this worker to eat." ”

"It's not that expensive, is it?" Hearing Chen Xin say this, Li Yulong frowned, feeling that two thousand square meters sounded quite big, and he didn't understand why Chen Xin didn't say enough.

"The planting greenhouse in my shelter is 200 square meters, and the yield per mu is 1,200 catties, and if you plant rice, you can harvest 1,200 catties in three seasons a year.

"Huh? No way? In a 2,000-square-meter area, the food grown is not enough for 50 people? Isn't there super rice in our country? What is this production for? Li Yulong seemed to have been poured a basin of cold water, and he suddenly felt disheartened.

However, Chen Xin said with a smile: "Super rice can indeed yield 2,000 catties per mu, but the dependence on seeds and fertilizers is very strong. Even if you can find someone to breed for you, the operating costs will be very high, so if you build a greenhouse just to grow rice, it will be a waste of time and energy. ”

Although Chen Xin said this with a smile, the people who came down with them around him heard the mockery in his words.

Because this is also in cooperation with the SWAT team, there is a team of SWAT officers who will be stationed here to maintain law and order in addition to daily patrol tasks.

Chen Xin was a little selfish and persuaded Uncle Ding that it was Qin Lan's team that was sent, so Qin Lan also came here with them today, responsible for checking the situation here and making some preparations for the stationing of the SWAT team in the future.

Hearing Chen Xin say this, Qin Lan frowned and asked, "But you can't stop planting food!" If we don't grow food because we don't grow food, won't everyone starve to death? ”

"That's true, but Xiaolong's plantation is of course prioritized for economic value." Facing Qin Lan's question, Chen Xin gave her a reassuring look, and then continued to explain: "Of course, this is all based on the premise of planting only one crop, in the current environment and existing planting conditions, the use of three-dimensional planting, as much as possible to make use of space, change the direction to expand the planting area."

As a result, the area of cultivation that can be used and the types of crops that can be grown are greatly increased, and if the aquaponics system is used, it can also provide aquatic products and the yield is more guaranteed. ”

"Three-dimensional planting, aquaponics? How do you get this? Hearing Chen Xin's words, Li Yulong suddenly became excited again, as if he was not the one who was disheartened just now.

"It's very simple, dig deep into the ground to make a pond to raise fish, spread planting boards on the surface to grow rice, and then set up several layers of hydroponic planting layers to grow vegetables and fruits." Chen Xin explained a few words briefly, looked at the empty shelter, and asked Li Yulong, "Xiaolong, have you thought about how to plan here?" You can't use all 2,000 square meters for farming, right? ”

"It's not impossible to use them for farming, right?" Li Yulong made a joke, but soon said: "I plan to divide two-thirds of the area for planting, and the remaining one-third of the area will be transformed into a residential area." ”

"It's going to be a little cramped!" When Chen Xin heard him make such an arrangement, he already understood his plan, and said with a smile and didn't say anything more, just followed the staff of the city government to check the situation of this shelter.

Although it was a small shelter, it was built to standard and the facilities were perfect.

Chen Xin followed the staff of the city government to inspect the circle and was very satisfied to see that the water and electricity facilities were still operating normally.

After introducing the interior of the shelter, the staff member talked about other supporting facilities: "After the disaster, the upper floor of this shelter was renovated, but only half of it was used as a coal-fired stack. Because the inside of the shelter is heated by a boiler, the boiler is installed on the upper floor, so the coal is also piled on the upper floor. ”

"Can this boiler be removed? We install ground source heat pumps, so there's no need to keep boilers. When Li Yulong heard Chen Xin and the city staff talking about heating equipment, he immediately didn't want that old-fashioned coal-fired boiler.

However, Chen Xin shook his head and said: "Keep it, in case there is any situation, when the operation of the ground source heat pump fails, there is a second set of emergency plans." Besides, the equipment can't go on forever, and it always has to be shut down for maintenance. ”

"Then listen to Brother Xiao Chen, but half of the upstairs area is stacked, it's too wasteful, right?" While Li Yulong nodded in agreement with Chen Xin's opinion, he also asked his doubts: "Brother Chen, do you have any arrangements for this?" ”

Facing Li Yulong's question, Chen Xin just smiled and patted him on the shoulder: "You have an idea, why ask me?" The boss is you, do what you want. ”

After speaking, Chen Xin walked towards Qin Lan, and the two of them got together with an intimate attitude, as if they were saying something private.

Li Yulong watched Chen Xin and Qin Lan walk to the side and talk about their affairs, shrugged his shoulders indifferently, and continued with the staff of the city government: "Since this is the case, then the boiler will not be dismantled, can the coal city government still supply it?" ”

"That's fine, but the city won't supply it for free." Although the staff of the city government were a little confused about who Chen Xin and Li Yulong were talking about, he would not be sloppy about his own work, and when he heard Li Yulong mention the coal supply, he immediately talked to him about the price.
