Building a Greenhouse

The time has entered July, and the drought that has lasted for half a year, no matter at home or abroad, still shows no signs of easing.

At this time, many people are vaguely aware of the seriousness of the matter. This is definitely not a simple natural disaster, but a major problem with the earth.

Starting from July 10, the world’s major grain-producing countries, including Daxia, have successively announced grain export bans.

Affected by this news, the international grain price has risen immediately, which has increased by hundreds of times, but there is no grain to buy in the market, and there is no market at all.

Severe drought has made the economies of various countries worse.

According to the forecast of the International Monetary Fund, the global economy is expected to shrink by 64.9% in 2022, and the global unemployment rate will reach a record high of 68.5%.

Great Xia has not announced the economic data for the first half of the year, but it must not be much better. People’s livelihood is in decline, and all industries are in depression. The same is not optimistic.

One bad news after another, but there is also good news

On July 12, the greenhouse project that Lao Xu’s family had been procrastinating and procrastinating finally took shape. Under the introduction of Wang Xiujuan, the construction party finally got together a sufficient amount of hollow tempered glass.

This kind of glass adopts two-layer tempered glass structure, which has good heat insulation, heat preservation and windproof performance, and is very energy-saving and environmentally friendly.

Taking advantage of the weekend rest, Xu Dong invited the designer of the construction party to his home.

A greenhouse is not a simple vegetable greenhouse. It needs an irrigation system, a ventilation system, a constant temperature system, and a heat preservation system. It can be said that although a sparrow is small, it has all the internal organs.

“Mr. Xu, in order to match the automatic irrigation system, I suggest that you build a small water tower here. After all, the water supply is tight now, and the water may suddenly be cut off one day.” Designer Sun said.

“Can’t we water it ourselves?” Yang Lina interjected.

“Of course, but there is a full set of intelligent control systems installed in the greenhouse. Manual work is definitely not as accurate as sensors, and it wastes more water.”

Xu Dong didn’t want his wife to work too hard, so he persuaded:

“They have a whole system, and if any link is missing, it won’t work, so don’t come up with random ideas, just listen to Xiao Sun!”

Yang Lina rolled her eyes and didn’t insist anymore.

“Xiao Sun, our house has a big water tank, do you think we can get water directly from the water tank?”

After Xu Dong finished speaking, he took Designer Sun to the concierge to look at the water tank.

After seeing it, Designer Sun shook his head and said: “No, irrigation water needs to be added with water and fertilizer during the irrigation process. It is safer to separate it from drinking water.”

“Okay, then build another water tower.” Xu Dong said simply.

Then there is the issue of heating.

“Mr. Xu, you can only use the air conditioner for heating here, but you must have a backup power supply, in case there is a power outage in the future…”

Xu Dong interrupted the other party with a wave of his hand, “You don’t have to worry about this, our house has a backup power supply, and the power will not be cut off.”

Designer Sun nodded in disappointment. He didn’t sell the generator, and the profit of this order was much lower.

“Okay then, Mr. Xu, I’ll show you the renderings right away, can you take a look at what needs to be modified?”

“OK!”

Half an hour later, the renderings came out, the whole greenhouse is made of light steelSkeleton structure, square appearance, high transparency, full of technological beauty, both Xu Dong and Yang Lina are very satisfied.

In the afternoon, the construction team began to enter the construction site. A total of eight workers came. Xu Ma specially boiled a large pot of mung bean soup to relieve the heat for everyone.

In the evening, the main frame of the greenhouse has been basically formed, and the only thing that needs to be installed is the equipment.

On the second day, the construction progress was significantly accelerated. By four o’clock in the afternoon, the entire project was completely completed, and the workers left soon, leaving only the technicians who were still debugging the equipment.

Xu Dong and his wife followed behind the technician, helping each other and familiarizing themselves with how to manage the greenhouse.

“This computer is equivalent to the brain of the entire greenhouse. You see, this is the control page, which can monitor the temperature, humidity and water content of the land in the greenhouse 24 hours a day.

When the external environment changes, the system will immediately make the optimal choice.

For example, when the temperature drops at night, the constant temperature system will automatically start to ensure that the greenhouse is always at a suitable temperature. ”

Xu Dong kept nodding. This highly intelligent planting model is very similar to the future planting factory. In a nutshell, the computer is responsible for planting the land, and the human is in charge of the computer.

It can’t be said that it is in charge, it can also be said that people cooperate with the computer, and the “farmers” do some auxiliary work. As for how to plant, it is completely up to the computer as a “person”.

“So, in the future, we don’t need to go to the field, and we can grow vegetables at home?” Yang Lina was not very happy, because growing vegetables like this is not fun at all.

“It’s almost like this, but things like planting, digging and harvesting still require manual work.”

“That’s about the same.” Yang Lina then worried again: “Master Liu, what should we do if the computer crashes?”

“It’s enough to restart it. The data here is not large, and basically there are very few crashes.” Master Liu comforted.

“Your system is specially used to grow flowers. You have seen it on my side. It is a vegetable garden. Will it be affected?” Xu Dong grasped the core of the problem at once.

“Please rest assured that our company is constantly updating the vegetable database. As long as you download it online in time, no matter what kind of vegetables you grow in the future, there will be no problem at all.”

Under the drought, the demand for greenhouse glass houses in the society is getting stronger and stronger. Of course, the greenhouse construction company will not turn a blind eye, and has already carried out relevant pre-research.

With the detailed explanation of the technician, Xu Dong and his wife gradually mastered the operation mode of the greenhouse.

It is very simple to say, as long as you understand the relevant data, and leave the rest to the computer, you will learn it in one go.

After the commissioning was completed, Xu Dong personally sent the technicians out of the gate. The greenhouse cost more than 800,000 yuan, which was seven or eight times more expensive than usual.

But it’s worth the money, at least the old Xu’s family won’t be short of vegetables in the future, and the dehydrated vegetables that Xu Dong hoarded will become redundant instead.

“Honey, this time I will plant more vegetables, a little of each.” Xu Dong said with a smile.

“Understood, do you want to plant some more watermelons? It’s too hot today, but they like watermelons the most.”

Madam Xu came over and interjected, “Growing watermelons is good, anyway, it won’t take up much space.”

“By the way, when will Aunt Wang plant her strawberries?” Yang Lina asked.

“I heard from Lao Wang that the strawberry seedlings haven’t grown well yet, and it will take about a week.” Mama Xu replied.

“Thanks to Aunt Wang this time!” Yang Lina said with emotion.

Xu’s mother took the opportunity to educate Xu Dong: “Son, you have to work hard. Look at how they handle this matter. In a word, our family’s big problem will be solved.”
