How much does it cost to build a 30-square-meter glass greenhouse?

Xu Ming specially searched for information online and learned about the general market.

The cost of building a glass greenhouse is roughly divided into several parts:

One, civil engineering costs.

It includes flat land, surrounding ring beams, surrounding wall skirts, independent foundations in the middle, scattered water slopes and drainage pipes around the greenhouse, and pedestrian roads in the greenhouse. According to the salary level in various places, the average cost is around 20 to 30 yuan per square meter.

However, these civil engineering work can obviously be completed independently by Xu Ming, so it does not require money.

Two, the cost of greenhouse skeleton steel.

The main skeleton materials of the greenhouse include main columns, wind-resistant columns, truss beams, enclosure beams, sinks, herringbone beams, side wall purlins, external sunshade columns, external sunshade horizontal beams, string rods, driving profiles, etc. The height of production-type glass greenhouses is generally less than six meters. Due to the different snow loads and span designs in different regions, the price of greenhouse skeletons is between 90 and 110 yuan/square meter

Of course, there will be no snow in the world where you can live, and there will be storms occasionally. However, to ensure the concentration of carbon dioxide, the empty height in the greenhouse is about three meters enough. The strength can be appropriately strengthened to ensure that it can be used for more than twenty years. The cost in this regard should not exceed 100 yuan/square meter.

Three, sunshade system and cooling system costs.

The stable temperature in the world of yours is not high and there will be no high temperature and scorching heat. This cost can be saved.

Four, ventilation system cost.

This can also be saved, but the ventilation holes must be retained. You should know that burning charcoal may produce carbon monoxide in a closed environment, which is a fatal threat to the human body. For the sake of life, ventilation is still needed occasionally.

Five, covering material costs.

The covering material is divided into top covering material and surrounding covering material. The top covering material is usually composed of single layer of tempered glass and aluminum profiles, and the surrounding covering material is composed of double layer of hollow glass and aluminum profiles. The cost of covering material is generally 90 yuan/square meter.

Xu Ming plans to choose a covering material with strong light transmission and good sealing to ensure that carbon dioxide does not escape in large quantities and saves the purchase cost of charcoal, so the cost is estimated to be 100 yuan/square meter (multiply by the area coefficient 2).

Six, irrigation system costs.

Growing vegetables requires a lot of water. During the growth period, it is necessary to water it every day. Although the 30-square-meter vegetable field is just the size of a living room, Xu Ming can finish it by taking a kettle himself, but it is still a bit troublesome to water it every day, so he has to build a simple irrigation system, which is best automatically controlled by the program and water is poured every day.

The cost in this regard is about 150 yuan per square meter.

Finally, the transportation, installation and management costs of all equipment.

The greenhouse installation is relatively large, and there are certain safety risks that require high-altitude operations, and it requires trained professionals. However, in Xu Ming's greenhouse, every screw has to be installed by himself. If you don't understand, ask which companies it is impossible to bring two people into the portable world. The on-site installation is completed... Just like building a house before, everything depends on yourself.

So these expenses can be saved, and the price is that Xu Ming has to pay some time cost and learn how to install it.

In summary, a 30-square-meter glass greenhouse can only cost about 13,500 yuan.

If you consider other costs and leave some redundancy, the total price should not exceed 15,000.

"A half-part land is 15,000 yuan, and a mu of land cannot be 300,000 yuan?"

"I heard that the market in Xia Country is that a vegetable greenhouse of ten acres has an investment of at least 2.3 million yuan. It seems that agricultural investment is very expensive and the risks are very high. If you engage in organic agriculture, not only will the investment be greater, but the agricultural products are too expensive and it is difficult to form a scale effect. The conclusion is that organic agriculture is a good direction for entrepreneurship, but there will never be many people to do it. At most, it is the self-entertainment of some petty-bourgeois circles and the internal circulation."

Of course, for Xu Ming, 15,000 yuan is just a small amount of money, and half of the output of the vegetable field is recycled into his own belly, improving his life, and not taking out.

So in the next few days, even though it was very cold outside, he still started to get busy.

Weeding, digging, and leveling.

Go out to purchase, contact suppliers, make demands, and pay for orders.

After the materials and equipment arrive, they will be transported to the portable world.

In this state, Xu Ming, who was dedicated, showed great enthusiasm for the small vegetable field of his own. On average, in every 24-hour activity cycle, except for 10 hours of sleep and 4 hours of meal rest, the total 14 hours must be occupied. Of the remaining 10 hours, there are 4 hours. Xu Ming used it to work and the labor intensity is very high.

Sometimes, standing in the sun, looking at the shadow waving the hoe and wiping the sweat flowing from his cheeks, Xu Ming was moved by himself.

"How is it, I'm working very hard?"

"In the world of portable people, I can definitely get the title of model worker, right?"

"People like me who have gold fingers are working, young people, what reason do you have to not fight?"

Xu Ming said boastingly, not paying attention to a certain chapter saying that there may have been comments like "Shut up, shameless old thief".

As for the other 6 hours, it is undoubtedly used to surf the Internet, play games, watch, and engage in various entertainment activities. These are the goals and expectations he strives for every day, and it is also the source of his happiness. It is hard for him to imagine that if he had not been these, even if he got ten portable worlds, his happiness would be reduced to one-tenth of his current life, or even lower.

But there are two small episodes here.

One is that Mr. Wang has been harassing him recently and has sent a lot of micro-chat messages.

"Xiao Xu, how did you meet my niece last time? Do you feel that your impression of my niece is okay?" Mr. Wang asked at the time.

"What's wrong? Aren't you just finished it when you meet? What's the impression?" Xu Ming replied.

"No, no," Mr. Wang seemed a little panicked and said anxiously: "Xiao Xu, my niece is at least good-looking. She has money at home. You guys don't have any idea?"

"No, I have hands and feet, why do you have ideas? No, Mr. Wang, what do you mean? You can't regret it, I have done everything I promised you. Don't go back on your word and want to cheat me again." Xu Ming noticed something was wrong and immediately asked coldly.

"If you don't cheat you, I will definitely not cheat you Xiao Xu. The problem is that something happened. My niece seems to be quite satisfied with you. Although I have said a lot of bad things about you, my niece doesn't mind very much... Xiao Xu, things have become tricky, and I don't know what to do next."

"That's not my business, you can find a way to solve it yourself."

"Xiao Xu, please help me again."

"I can't help with this kind of thing." Xu Ming flatly refused.

After that, Uncle Wang made a voice bombardment on him and asked variously, but Xu Ming deleted and blocked him, and his ears were immediately cleared.

Xu Ming knew it was impolite to do this, and something else was fine, but he could not do what Mr. Wang begged for. Last time, he reluctantly helped him because of friendship. But now that the friendship has been exhausted, he has no reason to help again.

Two days have passed.

The glass greenhouse in a flatter area on the south side of the grassy hill has already taken a rough prototype.

However, that afternoon, Xu Ming received two more micro-chat messages:

"Are you here, Xu Ming?"

"After the last meeting, you haven't contacted me much these days and didn't ask for the money for dinner. What's wrong with you these days?"

Lan Mengxin!

It was sent by the female writer who was recruiting a fortune.

Judging from the meaning of her words, she seemed to be kept in the dark by Mr. Wang. She didn't know his attitude, and might be misunderstood that he had that meaning.

Considering the other party's identity, Xu Ming didn't treat her like Mr. Wang, blocking her and deleting her. After all, this woman had never offended her.

"exist"

After returning, thinking about it, in order to dispel her fantasy, Xu Ming sent out a clear message and said: "I have been busy recently, but these days, I have also thought about it carefully and thought about my life. In the end, I still plan to struggle."

"So, I'm sorry."

What?

After seeing these messages.

Lan Mengxin in front of the phone was stunned.
Chapter completed!
