My courtyard shelter

Time has entered July, and the drought that has lasted for almost half a year shows no signs of easing, whether at home or abroad. read

By this time, many people were vaguely aware of the seriousness of the matter. This was definitely not a simple natural disaster, but a big problem on 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, international grain prices rose in response, increasing hundreds of times. However, spot grains are no longer available in the market, and there is no market for them.

Severe drought has worsened the economic situation of various countries.

According to projections by the International Monetary Fund, the global economy is expected to shrink by 9% in 2022, and global unemployment will reach a record high of 5%.

Daxia has not released economic data for the first half of the year, but it is certainly not much better. People's livelihood is in decline, and all industries are depressed. It is also not optimistic.

Bad news comes one after another, but there is also good news.

On July 12, the long-delayed greenhouse project of Lao Xu’s family finally took shape. With Wang Xiujuan’s introduction, the construction team finally gathered a sufficient amount of insulating tempered glass.

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

Taking advantage of the weekend break, Xu Dong invited the designer from the construction company to his home.

A greenhouse is not a simple vegetable greenhouse. It requires an irrigation system, a ventilation system, a constant temperature system, and an insulation 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 you build a small water tower here. After all, water is tight now, and the water may suddenly be cut off one day." Designer Sun said.

"Can't we water it with our own hands?" Yang Lina interjected.

"Of course you can, but there is a complete set of intelligent control systems installed in the greenhouse. Manual control is definitely not as accurate as sensors, and it also wastes more water."

Xu Dong didn't want his wife to work too hard, so he advised:

"Everyone has a complete system. No link is missing. So don't come up with random ideas. You should listen to Xiao Sun!"

Yang Lina rolled her eyes and stopped insisting.

"Xiao Sun, we have a big water tank at home. Do you think we can get water directly from the water tank?"

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

After looking at it, Designer Sun shook his head and said: "No, our irrigation system adopts an integrated design of water and fertilizer. For safety reasons, it is better to separate it from drinking water."

"Okay, let's build another water tower." Xu Dong said simply.

Then there is the issue of heating.

"Mr. Xu, you can only use air conditioning for heating here, but you must have a backup power supply in case of a power outage in the future..."

Xu Dong waved his hand to interrupt the other party, "You don't have to worry about this. We have a backup power supply at home and there will be no power outage."

Designer Sun nodded in disappointment and did not sell the generator. The profit from this order was much less.

"Okay, Mr. Xu, I'll give you the renderings right away. Can you see what needs to be modified?"

"OK!"

Half an hour later, the renderings came out. The entire greenhouse is made of light steel skeleton. It has a square appearance, high transparency, and full of technological beauty. Both Xu Dong and Yang Lina are very satisfied.

In the afternoon of that day, the construction team started construction, and a total of eight workers came. Xu Ma specially cooked a large pot of mung bean soup to relieve the heat for everyone.

By evening, the main frame of the greenhouse has basically taken shape, leaving only the equipment to be installed.

On the second day, the construction progress obviously accelerated a lot. By about four o'clock in the afternoon, the entire project was completely completed. The workers left quickly, leaving only the technicians still debugging the equipment.

Xu Dong and his wife followed the technician, and while helping him, they also became familiar 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 soil moisture 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 thermostatic 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 plant factories of the future. In a nutshell, computers are responsible for planting the land and people manage the computers.

It cannot be said that it is in charge, it can also be said that humans cooperate with computers. The "farmers" do some auxiliary work. As for how to plant, it is completely decided by the computer and the "human".

"So, from now on we can grow vegetables at home without having to go to the fields?" Yang Lina was not happy. Growing vegetables like this was no fun at all.

"That's more or less the case, but things like sowing, tilling, and harvesting still require manual labor."

"That's about the same." Yang Lina then said worriedly: "Master Liu, what should we do if the computer crashes?"

"Just restart it. The data in the greenhouse is not large, and crashes are rare." Master Liu reassured.

"This system of yours is specially used to grow flowers. As you can see here, it is a vegetable garden. Will it be affected?" Xu Dong suddenly grasped the core of the problem.

"Don't worry, our company is constantly updating the vegetable database. As long as you connect to the Internet and download it in time, there will be no problem no matter what vegetables you grow in the future."

Under the drought, the demand for greenhouse glass houses in society is becoming more and more vigorous. The greenhouse construction company will certainly not turn a blind eye to it and has already conducted relevant preliminary 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, the rest is left to the computer, and you can learn it once.

After the debugging was completed, Xu Dong personally sent the technician out the door. The greenhouse cost a total of more than 800,000 yuan, which was seven or eight times more expensive than the usual price.

But this money is worth spending. At least the Xu family will not lack vegetables in the future, and the dehydrated vegetables that Xu Dong hoarded have become redundant.

"Wife, this time plant more other vegetables, plant a little of each." Xu Dong said with a smile.

"I know, do you want to plant some more watermelons? It's too hot today, and Keke and the others like to eat watermelons the most."

Xu's mother came over and interrupted: "It's better to plant watermelons. Anyway, it doesn't take up much space."

"By the way, when will Aunt Wang's strawberries be planted?" Yang Lina asked.

"I heard from Lao Wang that the strawberry seedlings are not ready yet, and we have to wait for another week." Xu's mother 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 do your best. Look at what others have done. They solved our family's big problem with just one sentence."
