Zhang Nan was indeed shocked.

I almost thought I had a hat of forgiveness.

"Master, welcome home."

However, the sweet and intoxicating smile of the maid Lina made Zhang Nan feel the beauty of going home.

"Okay, go home, hahaha!"

Zhang Nan held one hand with one hand, hugged Xiasha and Lina, and walked into the farm center town with workers helping him get the luggage.

...

It feels really good to go home.

I wake up naturally when I sleep, and I have someone to serve me in dress and eat.

There is no work during the slack season in winter.

Except for a few things, most of the farm affairs were handled by Lina in an orderly and orderly manner.

So in order to reward Lina, Zhang Nan broke her body the day after returning to the farm.

Well, it's very moist.

But this aroused the dissatisfaction of the maid Xia Sha, as if her favor was only her, and part of it was stolen by Lina. She suddenly became a little sarcastic and always acted coquettish. Every time it was time to rest, she would occupy Zhang Nan's room in advance, saying that she would help the master warm the bed.

If Zhang Nan wanted to drive her out, she would immediately look extremely resentful, with tears in her eyes, as if she had been abandoned by someone.

In the end, Zhang Nan's solution was simple. Anyway, the bed was big, so it was better to sleep with each other. While meeting each other honestly, try to get as good as possible.

The two maids seemed to be more enthusiastic, so Zhang Nan lived a ridiculous life of "three times a day, three times a day", which was very harmful to the kidneys.

Okay, I can’t talk about this anymore, I will talk about it again, it’s 404.

Of course, there are several important things that Zhang Nan did not forget.

For example, I drove to Shuqing Farm and handed over Mu Ge's mobile phone to a manager named "Gabu" on the ranch. I helped repair several faulty machines and called the Development Zone to replenish 100 tons of oil. I then transported 800 tons of corn and 200 tons of wheat to solve the problem of feed shortage.

I worked for three days on these things.

Back to the internal affairs of the farm, there are two main problems that need to be solved: biogas shortage and continuing to farm.

Previously, Zhang Nan planted two crops of corn in a glass greenhouse, especially the second crop, which used heating for three months and consumed a lot of biogas reserves.

This resulted in only 52% of the biogas left in the gas storage station, which could barely provide the town with a year of heating.

This is obviously not enough.

It must be supplemented to more than 80% to be considered safe.

Zhang Nan could only call Han Wanzhang, the head of Kaituo District, to seek help.

"Give me another 200 tons of diesel or 100,000 cubic cubic gas, otherwise my farm may freeze to death this winter." Zhang Nandao.

"You boy knows that you have a problem for me."

Han Wanzhang said: "Diesel can give you another 100 tons, but if you have natural gas, in a while, there will be a natural gas pipeline to build the Great Wall defense line. It passes through our D9 development zone and just passes through your farm. When the natural gas is opened, just connect the pipeline to your farm and turn the switch at that time, you can refrigerate the gas storage station. This winter, don't worry about being frozen... Are you lucky? "

“Natural gas pipeline?”

Zhang Nan's eyes lit up and said, "Can I pump more gas, build a few glass greenhouses, burn natural gas to heat the greenhouses, generate electricity to provide lighting for the greenhouses. In this way, I can also grow land and vegetables in winter and provide fresh grain and vegetables to the development zone."

"No, no!"

Han Wanzhang immediately shook his head and said, "Natural gas is still a relatively valuable resource now. Millions of people on the front line are counting on this pipeline to ensure heating in winter. How can you be so extravagant that you can use it to grow vegetables? You can use it a little bit, and you can't waste it."

"This... I just planted dozens of acres of land, really can't?"

"No, the pioneering bureau is not as generous as this level. No one will die if they don't eat vegetables in winter. We have vitamin slices and dried vegetables, so don't think so far."

"……All right."

Han Wanzhang's words dispelled Zhang Nan's idea of ​​using natural gas to farm.

In an environment like Xuanmeng Continent, the price you pay for in winter is significantly greater than that on Blue Star. On the one hand, the light is weak and artificial lighting is required. In addition, the structure of Xuanmeng Continent is special. It is not a sphere and does not have a large amount of geothermal resources underground. Therefore, if the greenhouse is not heated, the crops can easily be frozen to death by low temperatures.

Therefore, in the Xuanmeng Continent, if you want to grow food and vegetables in winter, the price will be extremely high.

Even a loss-making business with far greater investment than returns.

Of course, there are also places such as "the volcano that lasts for thousands of years", "hot springs within a radius of thousands of miles", "the valley of Yongchun", and "the sea of ​​magma". They have a large amount of geothermal resources, which may be a good place to farm.

But unfortunately, the pioneering bureau occupies a barren land and does not have so many magical places.

what to do?

Can you only give up the plan to farm in winter?

In the distance, thick black smoke was spitting out from the towering chimneys, and the steel town opposite was spewing pollutants into the atmosphere.

If it weren't for Zhang Nan's farm being at the upper end and being less affected by pollutants, Zhang Nan had already gone over and complained many times.

I also remembered that when I drove by Steel Town two days ago, the red iron ore and black coal mines accumulated in the open space were like two giant mountains, and the number was unimaginable.

I remembered the scene of Steel Town turning on the furnace and making steel every day and being in full swing every day.

It seems that the temperature in the air has increased by several degrees.

There is a way!

Zhang Nan thought of a good way to farm in winter.

Use a large amount of waste heat generated during the steelmaking process in Steel Town.

"The steel town next to it has to refine tens of thousands of tons of steel every day, and at least several thousand tons of coal is burned. There are thousands of workers working in steel mills. I don't know how much waste heat is generated during the steelmaking process."

"I can use one percent of the waste heat, even if I can use one percent of the coal, it will be equivalent to dozens of tons of coal. Planting more than ten acres of greenhouse vegetables is definitely not a problem, and the development area will definitely not object. After all, this is a reasonable use of waste heat resources."

"The only problem is that this project. I don't know if Wu Zebin from Steel Town agrees with it. If he doesn't object, I have hope of starting this project."

...

March 10.

Zhang Nan drove a pickup truck and personally arrived at Steel Town.

At the entrance of the steel mill, I showed my purpose and told me that I soon met Wu Zebin, a dark-skinned, slutty beard, thin dress, and a layer of sweat on my forehead.

"Brother Zhang, what's the point of finding me?"

When he saw this neighbor Zhang Nan, Wu Zebin asked lukewarmly, and was very confused. The so-called neighbor next door was an enemy. Because of pollution problems, he was often troubled by his neighbors. Could it be that this person is also here to find fault?

"Angkor, I have a project here. I want to find you to cooperate with. I wonder if you are interested?" Zhang Nan said kindly.

"Let's talk about the cooperation project?"

Wu Zebin was stunned. It turned out that he was not a question of complaining. He immediately called out: "Let's come in and say it, it's a bit cold at the door."

"good."

As soon as he entered the steelmaking plant, Zhang Nan felt the rolling heat wave. The temperature inside the plant was at least 30 degrees. No wonder all the workers inside looked greasy and couldn't help but sigh: "It's hotter than turning on the air conditioner."

"Fortunately, steelmaking is quite comfortable in this weather. If it is hot summer, there is no way to start work. It can't stay in it for a minute, but it is suitable for work in winter."

"Angkor, the cooperation project I want to discuss with you happen to be related to your steel mill. I plan to build a glass greenhouse to grow vegetables in winter..."

After spending some time, Zhang Nan expressed his idea: to build a greenhouse with the help of waste heat from the steel mill.

"Use steelmaking waste heat to grow off-season vegetables?"

Wu Zebin was stunned and didn't react for a while, because it was the first time that someone proposed the idea of ​​combining steelmaking and vegetable cultivation.

"That's right, in addition to growing off-season vegetables, you can also grow watermelon, melon, grapes, strawberries and other fruits, providing more choices for the winter dining table." Zhang Nandao.

"Watermelon, fruit?"

Speaking of this, Wu Zebin couldn't help but secrete the saliva in his mouth and swallowed his throat one after another.

Because he calculated the time, since the beginning of winter, he hasn't eaten fresh vegetables and fruits for five or six months. Now, let alone watermelon, he doesn't even have to chew a cucumber. He mainly has various meats every day, and there are rarely greens on the plate.

The only vegetable is the bean sprouts that make people sprout.

Either it is a variety of pickled vegetables and canned fruits. You can eat them, but how can you compare to the freshest vegetables and fruits?

“This project is OK!”

Wu Zebin secreted saliva and said, "Look at the outside of the blast furnace, there is a layer of water-cooling and thermal conductivity system, which continuously guides heat to the outside. As long as we transform the water-cooling system and guide waste heat into the greenhouse, we can use it for growing vegetables. The renovation work is not large."

"But Brother Zhang, there is one thing you have to make in advance. I have to have a portion of the vegetables and fruits you grow in the greenhouse, and I will score at least 30% of the points."

"Okay, no problem!"

Zhang Nan smiled and said that the preliminary cooperation intention was reached.

Immediately afterwards, Zhang Nan picked up his mobile phone and called the relevant personnel of the exchange, asking them to provide materials that can build a 20-acre glass greenhouse. He wanted to grow vegetables and fruits in winter.

“We can provide the materials.”

After listening to Zhang Nan's project concept, the exchange discussed it and believed that fresh vegetables and fruits are a basic need in winter and have a large demand market. They immediately agreed to the project and said: "However, one-third of the vegetables and fruits grown should be taken out and supplied to the exchange. After this winter year has passed, there is no need to supply them. The greenhouse belongs to you personally."

"Yes, no problem."

Zhang Nan nodded, just one-third, this requirement is not an exaggeration.

What Zhang Nan pursues is not the vegetables and fruits themselves, but the "growth commission" during their growth process. Compared with this, vegetables and fruits are just accompanying products. Even if they are divided by 90%, Zhang Nan will not care about it.

However, during the specific implementation of the project, due to the serious lack of PE pipe materials for insulation on the exchange, it is impossible to lay a heat transfer pipeline that exceeds 10 kilometers and extends to Zhangnan Farm. Only the most ordinary steel pipes can be used to build a glass greenhouse 500 meters west of the steel mill.

Therefore, the greenhouse is within the scope of the Iron and Steel Town.

Wu Zebin said that there is no problem. In addition to mining areas, open spaces and wastelands in his steel town, Zhang Nan can build greenhouses there, as long as the waste heat energy from the steel mill is sent in.

"You can only place it next to the steel mill, and you can go to more places in the future."
