"So many shelves!" Although it was not the first time I entered the greenhouse, Song Qingyun was still shocked after coming in this time.

I saw a huge space in front of me. The dome at the highest point is five meters, all supported by arc-shaped steel frames. There are crisscrossing lines inside, wires, optical fibers and water and fertilizer spraying systems.

"The glass film functional greenhouse is good, not bad." The expert next to him nodded repeatedly, expressing his satisfaction with the project undertaken by Durimei.

On the other end, there are several staff members who are undergoing acceptance. They are the fathers of the manufacturer, Party A, who contacted by Professor Baima. The greenhouses of poor households are supported by them, and are used for the cultivation of new varieties and as the research internship base of Teacher Bai of Nongda University.

After some busy period, the main project of the greenhouse project in Hongshi Village was finally completed. Now 70% of the households are involved, including 80 poor households and 60 villagers who are at their own expense.

Although the criminal Wang Jun caused some losses to the villagers, fortunately, Song Qingyun discovered it early and he took someone to copy it after opening the casino for less than two days. On average, the average loss per capita for the villagers participating in the gambling was only about 5,000 yuan, and it was still affordable.

However, more than a dozen families regretfully withdrew from the project because they could not raise enough money to build greenhouses.

Song Qingyun was very annoyed and helpless, thinking, forget it, the big plan for poverty alleviation cannot be stopped because of those dozen families. How can this project be better in the future? If more than ten people have money, they want to participate, and welcome them at any time.

Hongshi Village is located in a flat dam in a ravine. Not to mention the mountains, the soil is poor and only corn can be planted. The yield of land is concentrated in the ravine and the area is not large. At this moment, they are used to plant economic crops such as grapes. In the sunshine, the entire flat dam is covered with PC sun panels, glass, and plastic film, presenting a postmodern beauty.

Song Qingyun never dreamed that this kind of thing that represented high-tech could be built in such a mountain, and his heart was full of a sense of accomplishment.

Of course, you have to wait until the entire project is accepted.

Our Comrade Xiao Song has a very distrust of Du Limi.

This old man is just a manager of a bag company. He has many ideas in his mind and thinks of cheating whenever he encounters something. He is afraid that he will start a bunch of tofu projects for money and have problems. What kind of face does he have as the first secretary have?

Du Limei was very angry about Song Qingyun's concerns and said, "Song Qingyun, what do you mean? Do you think I dare to eat any bad money? Am I really the kind of person who is shameless and lifeless when beating a tiger with bare ass?

Song Qingyun said you are.

Boss Du shouted, "I am the son-in-law of Hongshi Village, and my inn can be found in the village. If you really set up a stall, it would be fine if the poor households were poor. Anyway, Professor Bai gave money to build a greenhouse, and the others were at their own expense. Who wouldn't have given out 20,000 to 30,000 yuan? If I throw it into the water, I wouldn't have been beaten to death?"

When Song Qingyun thought about this, he felt a little relieved and said, if there is a problem with the poor households, you can't explain it, after all, you have missed the farming season for a year.

Du Limei: "Song Qingyun, why are you more nervous than me? Don't be nervous, don't be nervous, it's okay, everything will be fine. God will bless the good people, and you are a good person."

...

Boss Du is a talkative person. He is willing to please him and talks with the leader of the acceptance team and an old expert.

The experts also talked a lot, and the two of them were talking in an opportunistic manner.

Song Qingyun and the village cadres followed them. After listening for a long time, they gained a lot.

Experts say that because greenhouses can transmit light and keep warm, they are mainly used to cultivate plants in seasons that are not suitable for growth. You Hongshi Village have good solar and thermal conditions, so there is no need. However, the function of greenhouses is not just to keep warm, especially this kind of smart greenhouse. First of all, greenhouses can control pests, after all, it is a confined space!

The most important thing is that the humidity and carbon dioxide concentration/, especially CO2, can be controlled, which is a necessary condition for plant survival. Only when the concentration is controlled can the grapes grow well.

The experts did not say too profound theories, and the language was plain so that everyone could understand.

Hearing this, the village chief Liu Yonghua, who was following behind, said seriously: "It still needs to be kept warm. Although it is about twenty degrees during the day in winter and it is very hot, it is not surprising that the sun sets and reaches zero degrees. When I wake up in the morning, the ground is covered with white frost, and the crops are frozen to death by accident."

The expert nodded and said, in addition to keeping warm, it also needs to cool down in summer.

Acceptance is mainly divided into two parts, the first part is the cooling system in summer.

This system is actually quite simple. First, it is sprayed on the roof. There are many spray heads connected outside to cool down the greenhouse. Moreover, it can also wash the dust on the roof, similar to the spray heads of a car wiper.

Then the indoor fan cools down.

Immediately, electrician Gong Liushan turned on the fan. The breeze blew the wet curtain wall that had been wet by the spray head, and the air became wet and cool.

Because the greenhouse was sunny all morning, it was so hot that it was so hot that it felt so hot that I felt relieved. Chen Jianguo smiled and said, "It's comfortable, comfortable, I said, it's really hot, I'll switch to the greenhouse to enjoy the cool every day."

Gong Zhenxin scolded: "Your heart is so big, so wet, don't you be afraid of arthritis?"

In addition to these two items, the greenhouse cooling method also has a natural ventilation system. This system is very simple, except that it is to uncover the PC sun panel on the roof of the greenhouse to allow the air inside and outside to communicate.

In addition, the microspray irrigation system inside can also cool the indoors when working.

After talking about the cooling system in summer, we talk about the warm system in winter.

In general, there are three ways to heat up a modern greenhouse: atmospheric source heating, photovoltaic power generation system and fill light system.

Atmospheric source heating, as the name suggests, uses electricity to heat the air, floor heating, radiator and fan in the greenhouse at the same time and still maintain the temperature above 14 degrees. However, this system consumes a lot of energy, which is obviously not suitable for Hongshi Village. Especially for poor households, they eat enough, and you also ask them to spend a large amount of electricity bill first. It would be strange if they don’t call yellow. This system is only suitable for the north, only for large modern farms, and PASS first.

The optical power generation system uses solar energy to generate electricity to heat up the greenhouse. The investment is equally huge and not suitable.

Finally, Hongshi Village chose a fill light system. It uses sunlight during the day to heat up the greenhouse. At night, when the temperature in the greenhouse drops to the agreed value, the plant fill light will be automatically turned on.

Speaking of this, someone may ask, lamps also require electricity, which is another considerable electricity bill. What is the difference between it and atmospheric heating?

The difference is really big. First of all, this kind of lamp has very small power, and a hundred-watt can illuminate a large area. And because it is close to the plants, the heat effect loss is small.

The key is that this thing can increase the crop's harvest time by 20% in advance and increase the yield by 30%. Of course, this is mainly for northern regions, and in areas such as Hongshi Village, which have good solar and thermal conditions, the effect is not so obvious.

In general, the entire heating system is only used during the winter period from light snow to small cold, but it does not need to be turned on at other times.

Seeing this, Gong Liushan demonstrated and turned on the LED light. He saw that there was a red and blue light on everyone's heads. The expert hurriedly said, "Okay, OK, it's too hot, I can't stand it!"

Everyone laughed.

While watching, the acceptance team listened to Boss Du’s introduction. They took photos and recorded items from time to time, and then remembered something in the notebook.

As the village director, Liu Yonghua was a little anxious and couldn't help asking if he could cut grapes now.

The acceptance team looked at him strangely and said, "You have to ask Professor Bai this, he is the expert, we are only responsible for acceptance and then allocating funds."

It turned out that the main project of the greenhouse has been completed and it is time to plant grapes. However, the supporting spraying system, water and fertilizer drip irrigation system, and cooling and heating system have not been installed yet.

Judging from Durimi's progress, all these systems need to be installed and debugged for several months. Fortunately, it is still early in the summer and these systems cannot be used.

After so much time, Lao Du only installed more than ten acres of land. Although he studied engineering, he was still a little unsure about these new technologies. He felt that his knowledge structure was a bit behind the times.

Liu Yonghua smiled and said, "Okay, then we'll ask Professor Bai when he will send the seedlings here."

After the acceptance team transferred the greenhouse, they went to the main control room again.

The control room was very simple, just a glass house was built on the hillside, which looked no different from other greenhouses. There were tables and chairs inside, and there were several computers on the table. I was sitting there fiddling.

Her education is quite good among village cadres, she is young, and she is quick to get started with this system.

The ground of the control room was still exposed, and some workers were laying some aluminum alloy buckle boards. It will take some time to prepare the situation.

The acceptance personnel also conducted progress inspections.

The old expert smiled and said that in fact, it can be expanded to become a restaurant.

Chen Jianguo asked strangely, "Is it necessary to go here to cook for a meal?"

Experts say, otherwise, in addition to high-value-added planting, many places like this, also engage in ecological tourism, sightseeing, picking, catering and entertainment.

He also said, I don’t understand the cultivation of cash crops, but it takes more than a year or even two or three years to produce benefits from crops to harvest. During this period, farmers have to eat and make money, right? Ecological tourism is also a way, and other places do this, so I just talk about it casually. As for whether to listen or not, it’s up to you.

Chen Jianguo smiled again and said, "How come this grape will take a year or two to bear fruit. If others come to travel, can you see the green grape leaves?"

Gong Zhenxin said seriously: "You can see the snow-capped mountains, old houses and old streets here. After seeing it, it's good to come over to have a meal."

Chen Jianguo: "Tourists can eat in the farmhouse run by farmers themselves. Why do you have to go to the field so troublesome?"
