Big camphor tree base.

Since Li Yu and the others left, construction in the base is still in full swing.

It is October now. Since the last high temperature surge, the temperature has dropped sharply and then returned to a slightly normal temperature. But now it is October. Compared with the normal temperature in October in previous years, it is still colder than in previous years.

of.

The temperature at night can reach zero degrees, and when you wake up in the morning, you can see frost outside.

Frost.

This year's winter is earlier than in previous years.

Autumn seems like not a few days have passed.

There is a large temperature difference between day and night. The hottest time at noon during the day can reach more than ten or twenty degrees above zero. At night, the temperature drops sharply, reaching around zero degrees.

Regarding the base’s outdoor greenhouse plan, it was officially launched the day after Li Yu and the others left.

Originally, He Chao and Xiao Jun obtained hundreds of tons of steel from the steel plant in the northeast of the province, and used part of it on the wall, but there was still a lot left.

It is urgent to build an outdoor greenhouse.

One reason why the Da Zhangshu base is internally stable now is that the Li family is the core of the base and has absolute leadership. Important positions are basically in the hands of the Li family.

Another extremely important reason is that there is abundant food.

But food cannot be left empty-handed.

Affected by natural disasters, late rice planting in the base has not been carried out outdoors.

The outdoor planting occupies dozens of acres of land. If it cannot be planted, it is a small matter to waste the land, but it is a big matter not to harvest food.

Ding Jiu, Xiao Qian and others quickly made plans for the construction of greenhouses in the inner and outer cities.

In addition to them, Anya also put forward some suggestions for the greenhouse to be built. After all, the greenhouse is built to grow crops, so the outdoor greenhouse must consider the environment required by the crops.

In the duty room and temporary conference room, everyone began to formulate a specific implementation plan for the construction of the outdoor greenhouse.

The issue of steel has been resolved, but the material covering it has not been finalized.

Greenhouses mainly use three materials.

Plastic film, PC solar panels, glass.

"I think it is most appropriate to use solar panels as the covering material of the greenhouse. This hollow sheet made of plastic is light in weight, weighing 1.4~1.5kg per square meter, has high hardness, is commonly known as ring steel, and is light-transmitting

The efficiency is about 80%, which fully meets the needs of plant production. The insulation effect is good and the service life can be more than ten years. And, as far as I know, there are two factories in Gan City that produce this material." Ding Jiu said.

said.

Xiaoqian hesitated and said: "Although the solar panels have a long service life, they are also complicated to install. If all the planting areas in the base are used for this, it will be a very big project. Plastic films are easier to install.

.And some plastic films have strong tear resistance, high temperature resistance, cold resistance, and good light transmittance. Most greenhouses before the end of the world used this."

The second uncle thought for a while and said: "If the difficulty of installation is not considered, which material will be more suitable?"

Anya said: "Of course, the solar panel is more suitable. Compared with glass, it is lighter in weight. Compared with plastic film, although it is heavier, it is less likely to be damaged."

Hearing what Anya said, the second uncle said: "Then use PC solar panels. But don't worry about it. You should build the basic steel frame first. Anyway, the covering material is not available now."

The second uncle looked at He Chao and said: "He Chao, add this material to the material exchange list and let the base cooperation staff and non-staff personnel collect this material."

He Chao, who was listening attentively, nodded immediately after hearing what his second uncle said, rolled his eyes, and asked, "How to calculate this exchange ratio?"

The second uncle struggled for a while and asked the uncle and others: "How much do you think is appropriate?"

The uncle didn't know much about the material exchange ratio. He had always been responsible for the security of the base. When asked about this, he didn't know what the appropriate ratio was.

But Ding Jiu knew this material. He had worked as a contractor and in management before, so he said: "This material is relatively light. With the same weight, the volume is several times that of steel. Why not calculate it as three times that of steel?"

Bar?"

After hearing this, the second uncle nodded slightly, thinking that this suggestion was acceptable.

So he said to everyone: "What do other people think?"

"I have no objection," the uncle said.

"Okay, that's it." Father Li said.

...

Seeing that no one had any objections, the second uncle said to He Chao: "It is also calculated based on weight. One ton of PC solar panels can be exchanged for 6 kilograms of grain."

He Chao nodded and immediately recorded the exchange ratio in his notebook.

The second uncle looked at everyone and said: "Okay, let's build the basic framework for the time being. Ding Jiu, Xiaoqian, you have to hurry up and build the steel frame as soon as possible. He Chao, you also release the task as soon as possible.

, collect the covering material.

Today is colder than yesterday. Everyone knows how cold it was last winter, and there is not much time left for us. It is not easy for us to carry out construction in an environment that is too cold. While the daytime temperature is still okay, we can work as soon as possible.

Let’s get it done in two weeks.”

Ding Jiu Xiaoqian, He Chao and others nodded slightly to express their understanding.

"Okay, let's get to work quickly," the second uncle said to everyone.

Everyone left one after another.

"By the way, Anya and Xiaoshi will stay here for a while." The second uncle said to Anya and Xiaoshi who were about to leave.

The two of them were a little confused and stopped.

Walk to my second uncle.

The second uncle looked at them and said: "Before Xiaoyu left, he specifically mentioned to me about the current underground planting base. Did you encounter any problems? Do you need help?"

Anya rolled up the book in her hand and said to her second uncle: "There are no problems with light, water, and fertilizers. It's just that scale insects have appeared recently. To kill scale insects, avidemiprid is used. I talked to Bai Jie about this."

, she can configure it there. There is no big problem."

This chapter is not over yet, please click on the next page to continue reading! The second uncle was a little nervous when he heard that there was an insect infestation, but he heard that Bai Jie could solve it.

He immediately breathed a sigh of relief and said: "That's okay. If you have any needs or any problems in the underground plantation, you must report them as soon as possible."

Anya and Xiaoshi nodded.

"Well, then you go and do some work." The second uncle said to the two of them.

The two resigned and left the duty room.

The second uncle waited until the two left and then walked out of the duty room.

Father Li was looking at the mountains and forests in the distance on the wall. He was lost in thought. He heard footsteps behind him and saw that it was his second brother.

"Hongda, didn't Xiaoyu and the others say they would be back in two days at most? Today has passed immediately. If they haven't come back yet, will there be any accidents?"

The second uncle looked at his eldest brother, sighed, and said: "Brother, Lao San and Xiaoyu have gone out, there will definitely be no problem. Don't you know that kid Xiaoyu? He always does things safely."

Father Li shook his head and said: "Xiaoyu, this child, has always been independent. He doesn't like to communicate with me. When he came back, he wanted to build a farm. Later I saw him killing people and thought about how he became like this. But later

Only then did I realize that what he did was right. As a father, I am not competent at all and I don’t understand him at all."

The second uncle looked at Father Li and comforted him: "No matter how he changes, his surname is still Li. He is still your son and my nephew. He will never do anything bad to our family.

Moreover, it has been almost two years. He has resisted a lot of pressure for this base and for everyone. Brother, don’t think so much, they will come back."

Father Li breathed a long sigh of relief and nodded.

He smiled and said, "I've seen that boy Haoran recently, and it seems that he has a situation with Xu Zhen's sister."

The second uncle scratched his head in a rare move. The brat he raised at home has now learned how to serve cabbage.

"Young people's affairs are up to them to decide. I have no control over them anyway," said the second uncle.

"Hmm. I won't talk to you anymore. I'm going to look at the underground pipes. I heard Xu Zhen said that the underground culvert at the back door is cracked." Li's father said.

"Okay, I'm on duty here."

.....

Orange Island Head.

Evening light.

There are many birds in the city that use this place as a nesting spot.

There are no busy vehicles or bustling people in the city, making it look extremely empty.

In the quiet city, in the sunset, Li Yu and the others stood on a high-rise building and looked down, but no one could be seen.

There is an inexplicable sense of absurdity.

I took off a walkie-talkie headset and put a Bluetooth headset into my ear.

He took out his cell phone and played a song.

Piano music plays, a Lullaby.

Frost leaves know autumn, and the foggy forest in the mountains makes my heart yearn for it.

Music is a medicine that heals the human spirit.
