After making up his mind, Xiong Zhengxian didn't let Zhang Fan wait for a long time, and hurriedly called to inform him, saying that he had arrived in Zhangjiazhai.

Xiong rushed to Zhang Fan's house first, and it was very unexpected that one of the most luxurious houses in the village was Zhang Fan's. After all, from what he had just learned, he knew that Zhang Fan was the richest person in the village. From his handwriting of 2 million greenhouse planting in one go, you can also get a glimpse of one or two.

But the one in front of me is an old mud brick house from decades ago!

"The outside are the materials, and the steel frame doesn't need to be looked at much, it's all the same. The real difference is the insulation film. Xiong said to Zhang Fan first.

The steel pipe used for erection is a hot-dip galvanized pipe, which is to react the molten metal with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. This kind of steel pipe has strong corrosion resistance, high hardness, and is not easy to bend and deform.

The insulation film is a transparent plastic film, but the thickness is different, the thicker insulation effect is good, the service life is also high, and the price is naturally needless to say.

In fact, the most advanced is still a glass greenhouse, but I am afraid that the fraud is not something that ordinary people can afford. is so high-end, Xiong Zhengxian will not act as an agent, and there is no business to do at all.

"I'll see. ”

As soon as Zhang Fan finished speaking, he saw that outside, the monkey with cheap hands had already pulled out the plastic film that had been rolled up.

Xiong Xianxian's face twitched, and he thought to himself: You still have monkeys?

When they first entered the door, the eyes of the big rooster made their hearts tremble, and now a monkey came out?

Zhang Fan's face sank: "If you mess up again, I'll send you back to Qingtian Temple." ”

The monkey who was playing stiffly and looked at Zhang Fan, although he couldn't understand human words, but the monkey still had the ability to observe words and colors, and immediately rolled back.

"It's so smart!" said the technical master Lao Chen.

As soon as he turned his head, he accidentally saw a photo on the wall: "Your dog is also good-looking." ”

Poor Lao Chen still can't tell if it's a fox, seeing that there are photos of pets posted on the walls, it seems that he likes that dog very much, right?

They would never have thought that the photo was not posted by Zhang Fan's family at all, it was completely a fox narcissistic stinky display. Zhang Fan suspected that at the rate at which the number of fox photos increased, this hall would be filled with its photos sooner or later.

After Zhang Fan heard this, he almost stumbled.

Chen Baoli Wang Feihong laughed: "That's not a dog, it's a fox." Moreover, you wouldn't guess that the photo was taken by the fox himself and given to it by tourists and then ......"

Before he could finish speaking, a fox slipped in outside, holding a picture that seemed to have just been printed.

Zhang Fan was full of black lines, and he didn't know what to say, so he watched the fox entertain himself, and soon there was another photo on the wall.

"Huh...... Hehehe! Just get used to it. Wang Feihong felt a little toothache.

"I'm used to it. ”

"......" Xiong Zhengxian watched this scene a little absurdly.

Zhang Fan walked out and pinched the plastic film, which was relatively thick, tough, and transparent. If the transparency is not high, it will have a great impact on the photosynthesis of plants.

Anyone who has read biology knows that in order for plants to grow, they must photosynthesize, just like humans need to eat when they grow up.

These plastic films, in addition to light transmission and thermal insulation performance, also have to refer to its durability, that is, service life.

According to Xiong Zhengxian's introduction, his film is cost-effective and has a slow aging rate.

In the process of using plastic film, under the action of light, heat, machinery, chemicals, microorganisms, etc., it is often soft and hard, the light transmission function declines, and the color gradually changes to brown and yellow, and finally, even rubs it into pieces by hand, which is called the "aging" of plastic film.

In addition, Zhang Fan looked at a lot of things and realized that he needed so many materials.

Greenhouse joint pipe, greenhouse pressure roof spring, greenhouse film groove, greenhouse film spring, greenhouse sheath, greenhouse film card, greenhouse diagonal brace, greenhouse U-shaped card, greenhouse clamp, greenhouse fixer, greenhouse connecting piece, greenhouse film line, etc.

Xiong rushed to introduce them one by one, and some of them were also picked up by themselves, and they hit the ground hard, so that Zhang Fan could see the quality and show that they were leveraged.

"What we want to build is a good greenhouse that can adjust the size of the air outlet. Xiong said first.

Insiders will know that the size of the spring tuyere cannot be completely defined by a certain data, because the structure of the greenhouse is different, and the time and speed of cooling are also different.

In addition, when erecting the frame, the arch of the greenhouse needs to be further calculated and determined in order to make the most scientific greenhouse.

The greenhouse with a large camber is easy to discharge along the upper part of the greenhouse film because the camber of the shed surface is suitable, and a better air release effect can be achieved even if the air outlet is small. The low old shed with a long planting life, because the arch of the greenhouse is smaller, the shed surface is flat, the hot air flow in the shed is discharged from the air outlet slowly, and the temperature in the shed is high.

"How many levels of wind can the greenhouse you build resist?" asked Zhang Fan.

Although Zhangjiazhai is surrounded by high mountains, in the summer, there is also the possibility of typhoons, almost once or twice a year.

Therefore, the greenhouse must be able to resist strong winds, otherwise bad luck, if there is a typhoon, his loss will be great.

"Below level 10, there will be no problems. If it is more than level 11, not only me, but others are helpless to do it. "I can only say that if there is really a typhoon that exceeds the 11th level, I can only consider myself unlucky.

Zhang Fan listened and nodded slightly, even if he can resist level ten, it is okay.

Come to more than eleven or two, not to mention these built greenhouses, even their mud brick houses are not safe, the tiles on the top are also flying like darts, as long as the wind lasts for a minute or two, the roof will have to be overhauled, and there is no luck mentality.

"Then let's go and see the land where the greenhouse is going to be built!" said Xiong Zhengxian again.

They need to plan how to build according to the shape of the land, and build the greenhouse in the most reasonable way, so as not to waste too much land.

"Well, let's go, go that way, the valley is all mine. However, about half of it is used to grow vegetables, and there is no need for greenhouses for the time being. Zhang Fan led the way.

Later, Chen Baoli also followed, and the construction of Zhang Fan's fruit orchard was closely related to him and was also very concerned.

Soon, the old village chief and other village cadres, as well as some villagers, also followed. They are all curious, what does it take Zhang Fan to throw in a huge sum of two million?

They had heard explanations that greenhouses were very good, but they had never seen them before. Or have seen it on TV, but they don't know each other either.

What they can understand is to "build a house" on the land so that the crops can grow inside the house.
