Chapter 163

Push open the heavy protective door that was originally closed, and the small shelter that was originally closed opens the door again.

Standing at the door, Chen Xin can still see some debris scattered on the ground, which is obviously left over from the previous evacuation.

"It looks like it needs a good cleaning." Although they haven't entered yet, Chen Xin and Li Yulong's first impression of this small shelter is that it's a bit dirty.

"After evacuating people who used to live here because of oxygen supply problems, the shelter was temporarily sealed up." The staff sent by the city government heard Chen Xin's comments, but they didn't feel anything wrong. They just nodded and introduced the situation here: "this refuge was originally an underground parking lot, with two floors up and down, each of 2000 square meters. Because only the second underground floor meets the civil air defense standards, only this floor has been transformed into a refuge, designed to accommodate 1000 people. "

"A thousand? That sounds big! " Li Yulong listened to the introduction of the staff of the municipal government. As he walked in, he asked Chen Xin, "brother Chen, do you think we can use such a big place?"

To this question, Chen Xin just shook his head and replied, "it's not enough. Two thousand square meters is only three mu. If you are planting vegetables and fruits, it's OK. Growing rice is not enough for the workers."

"It's not that expensive, is it?" Hearing Chen Xin say so, Li Yulong frowned and thought that the two thousand square meters sounds very big. He didn't understand why Chen Xin didn't say enough.

"The greenhouse of my refuge is 200 square meters, and the yield per mu is 1200 Jin. If you plant rice, you can harvest 1200 Jin in three seasons a year. How much do three people eat, but not four people. Do you still think this place is big?"

"Ah? no Two thousand square meters of land, growing food is not enough for 50 people to eat? Isn't there super rice in our country? What's that for? " Li Yulong seems to have been splashed with a basin of cold water, and he suddenly feels disheartened.

However, Chen Xin said with a smile: "super rice can indeed yield 2000 Jin per mu, but it is very dependent on seeds and fertilizers. It needs to change seeds one year after planting, otherwise the degradation will be very serious. Even if you can find someone to breed for you, the operating cost will be very high, so if you build a greenhouse just to grow rice, it's just a waste of time and energy. "

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

Because of the cooperation with the special police team, a special police team will be stationed here to maintain law and order in addition to daily patrol tasks.

Chen Xin is selfish and persuades uncle Ding to send Qin Lan's team. Therefore, Qin Lan also came here today with them to check the situation here and make some preparations for the future stationing of the special police force.

When Chen Xin said that, Qin LAN frowned and asked, "but we have to plant grain! If we don't grow food because we are short of it, won't everyone starve to death? "

"It's right to say that, but Bruce Lee's priority in planting is to obtain economic value." Facing Qin Lan's question, Chen Xinchong continued to explain after giving her a comforting look: "of course, this is all based on the premise of planting only one kind of crop. In the current environment and existing planting conditions, the three-dimensional planting should be adopted, and the space utilization should be changed to expand the planting area as far as possible.

In this way, the usable planting area and the variety of crops that can be planted will be greatly increased. If the fish vegetable symbiosis system is used, aquatic products can be provided, and the yield will be more guaranteed. "

"Three dimensional planting, fish and vegetable symbiosis? How do you do this? " After hearing Chen Xin's words, Li Yulong suddenly became excited again, as if he was not the one who had been disheartened just now.

"It's very simple. The ground is dug deep to make a pond for fish culture. The surface is paved with planting boards to grow rice, and then several layers of hydroponic planting layers to grow vegetables and fruits." Chen Xin simply explained a few words, looked at the empty shelter and asked Li Yulong, "Bruce, do you have a good idea of how to plan here? Two thousand square meters can't be used for farming? "

"It's not impossible to use them all for farming, is it?" Li Yulong joked, 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."

"That place will be a bit crowded!" When Chen Xin heard of his arrangement, he already understood his plan. He said with a smile, but he didn't say anything more. He just followed the staff of the city government to check the situation of the shelter.

Although it is only a small shelter, it was built according to the standard at the beginning, and the facilities are perfect.

Chen Xin followed the staff of the municipal government to make an inspection tour. He was very satisfied with the normal operation of the water and electricity facilities.

After introducing the internal situation of the shelter, the staff member talked about other supporting facilities: "after the disaster, the upper floor of the shelter was transformed, but only half of it was used as a coal stack. Because the shelter is heated by boilers, which are installed on the upper floor, so the coal is also piled on the upper floor. "

"Can the boiler be removed? We're installing ground source heat pumps. There's no need to keep the boilers. " When Li Yulong heard Chen Xin and the municipal government staff talking about heating equipment, he immediately didn't want the old-fashioned coal-fired boiler.However, Chen Xin shook his head and said, "keep it. In case something happens, when the ground source heat pump fails, there is a second emergency plan. Besides, the equipment can't run forever. It has to be shut down for maintenance. "

"Listen to brother Chen, but half of the area upstairs is too much for stacking, isn't it?" Li Yulong nodded to agree with Chen Xin's opinion, but also asked his doubts: "brother Chen, do you have any plans for this?"

Facing Li Yulong's question, Chen Xin just patted him on the shoulder with a smile: "you have ideas. Why ask me? The boss is you. Do as you want. "

Finish saying, Chen Xin then walked toward Qin LAN in the past, two people attitude intimate get together, seem to say what private words.

Li Yulong watched Chen Xin and Qin LAN go to one side to talk about their business, shrugged casually, and continued with the staff of the municipal government: "in this case, the boiler will not be dismantled, can the municipal government supply coal?"

"It's no problem, but the city government won't provide it for free." Although the staff of the municipal government can't figure out who is in charge between Chen Xin and Li Yulong, they are not careless about their own work. When they heard Li Yulong talking about coal supply, they immediately talked about the price with him.
