Scholars in the courtyard.

Chapter 1533. What to use for insulation?
After lunch, Ran Qiuye and other women returned along the same route carrying baskets and wooden barrels to clean up their homes.

The men rested for a while and continued working.

There is strength in numbers.

This is proven here.

Hundreds of people worked around the five construction sites for most of the day, and finally completed the renovation of the original pig pen.

Looking at the heightened and thickened walls and ceiling, and the wooden piles erected one after another, everyone felt a sense of accomplishment.

"The next step is to set up the shelf and put on the film!"

Yang Xiaotao said on the side, although the greenhouse in front of him was a bit rough, this was already the fastest speed.

Most importantly, it does not affect use.

On the side, Lao Jin and his grandfather were sitting on a cart talking.

"I haven't worked for a long time, and it hurts when I do it!"

Lao Jin rubbed his arms and sighed. Even though he was three years younger than Mr. Yang, when it came to work, he really couldn't keep up with his speed.

Mr. Yang picked up the cigarette pole again. In comparison, this kind of dry cigarette is more powerful when working.

"You can have a good sleep tonight!"

The grandfather was smiling on the side. There were many common topics between the two, especially when fighting Japanese.

Now they have worked together, and with the presence of Yang Xiaotao, they have become more cordial to each other.

"That's true! But it's so cold here!"

Mr. Yang smiled after hearing this, "You'll get used to it if you live for a long time."

"In the past, my family's cotton-padded jackets had to bear the labor of work, but now that life has improved, children can run in the snow."

"Yeah, compared to before, it's better now!"

Lao Jin held a cigarette in his mouth and sighed.

"When you have time to go to Shanghai, I will take you on a boat trip on the Huangpu River~"

Mr. Yang smiled and said, "I have been to the Yangtze River, but not to Shanghai. At that time, I followed the boat to Jinling..."

Hearing this, Lao Jin laughed and said, "I forgot about this. But Shanghai is much better now than before. There are all kinds of good things!"

After hearing this, Mr. Yang smoked his pipe twice and asked, "Is there a greenhouse?"

Hearing this, Lao Jin frowned and thought for a while, and finally said, "No!"

"Oh!"

Mr. Yang responded, and Lao Jin looked a little confused.

Then I heard Mr. Yang ask, "Speaking of which, although we are busy as dogs, we really don't know what this greenhouse is!"

"If Xiao Tao hadn't come back and said what the greenhouse was for, we wouldn't have known we could still farm in the winter!"

"This thing sounds strange."

Hearing this, Lao Jin nodded silently. He had only heard of it, but he really didn't understand how to do it.

"This greenhouse used to be like a greenhouse! Our country has had it since ancient times!"

The old principal next to him opened his mouth to explain, and several people looked over.

"Of course, this is just like getting ice in the summer, it is the privilege of the rich and powerful!"

The old principal lamented, "In the past, the princes and nobles would have people build greenhouses just to satisfy their appetites in winter."

"This thing is not simple. It requires not only dedicated personnel to take care of it, but also specialized technology. A greenhouse consumes more materials than ordinary people in a year."

"It's as warm as spring in there, which is perfect for growing vegetables and fruits."

"But that can only be enjoyed by the upper class. It is a waste of money and people, and it would be nice if the people at the bottom can have firewood to burn."

The old principal said and looked at the crowd not far away, "This time, we are not building this greenhouse for some noble lords, but for the working people!"

After hearing this, everyone nodded and looked at the greenhouse with a different color.

This belongs to the working people!
On the other side, Yang Dazhuang and others followed Yang Xiaotao and listened to how to build a greenhouse, memorizing each one carefully.

Yang Xiaotao said that this greenhouse was not built for temporary needs. It might be possible to grow vegetables in the future.

By then, you can also eat leeks in winter.

A few people didn't dare to be careless, and everyone followed and listened.

"The growth of plants in a greenhouse mainly depends on sunlight and temperature."

"This thing can be understood as a separate space, or it can be regarded as spring."

"So, this wall must be thick so that it can block the northwest wind!"

Yang Xiaotao patted the newly thickened brick wall. After filling it with soil, it has reached a thickness of one meter, so that it can effectively maintain heat.

"During the day, we must let the light shine in through the greenhouse film, so that the plants inside can receive sunlight..."

"So this film is very useful. It must not only meet the light transmittance, but also be strong and not break when poked. It must also..."

Yang Xiaotao said, and Yang Shitou on the side listened and asked, "Brother Tao, do we have such a good film?"

Everyone also looked over, and Yang Xiaotao's heart sank.

This question is also what Yang Xiaotao wants to know.

You know, in order to purchase this batch of films, the alliance is very open-minded.

The price has increased tenfold!
If it weren't for the fact that the country had earned a lot of foreign exchange during this period, and the herb was in urgent need, the higher-ups wouldn't have readily agreed.

Even so, he spent a lot of money in a humble manner.

This also makes people in China realize that sometimes, you can’t buy things just because you have money.

Just like special medicines for treatment, you can sell them to obtain foreign exchange, but if you use the money to buy things, others will earn it back at a higher price.

This is the advantage of a seller's market.

The difference is that now Huaxia also has certain advantages, which is much stronger than the original Konglai.

As for exchanging goods for goods, using medicines in exchange for materials and machines that are urgently needed in the country, the foreign trade side is negotiating on this, but it is not as difficult as buying enough.

If I had known, it would always be a small number of people who have the right to speak abroad, and their policies will not consider the life and death of the people at the bottom.

Seeing everyone around him looking at him, Yang Xiaotao showed a confident smile.

"Our country is organizing scientific research units to develop it, and it won't take long to have it ready."

"But we are in a hurry to use it this time, and the scale is so large, so I bought some from the alliance for emergency use. Don't worry, we will have our own film in the future."

Hearing what Yang Xiaotao said, the people around him were also greatly encouraged.

"This film must be de-iced and snowed in time so that it can retain heat and prevent collapse..."

Yang Xiaotao continued to explain. Although everyone did not see the greenhouse being built, they could still imagine what to do.

"You must also pay attention to the temperature at night. It must be controlled well and not too cold. If it is too cold, the seedlings inside will freeze to death."

"So the soil used in the greenhouse must be good soil, and pig manure must be used. It would be better if there is chemical fertilizer, so that it can grow vigorously in winter..."

With Yang Xiaotao's explanation, the crop experts gradually understood what a greenhouse is, how to operate a greenhouse, how to grow food, etc... Just as Yang Xiaotao was leading people back, Yang Shitou, who was behind him, suddenly muttered, " It’s so cold at night, how much firewood do we have to burn?”

Yang Xiaotao was walking in front. Hearing this, he immediately laughed and said, "Actually, it won't take much, just put a blanket on top of the film!"

"What blanket?"

Yang Dazhuang suddenly spoke on the side with a complicated expression on his face.

Yang Xiaotao was also suddenly stunned, and then looked at Yang Dazhuang, "Uncle Dazhuang, are there no straw blankets in the village?"

Grass blanket?
Everyone looked at each other.

Seeing this, Yang Xiaotao realized that it seemed that he had overlooked an important thing!

……

Yangjiazhuang, brigade headquarters.

It gets dark early in winter. It's just after six o'clock now, and it's already so dark outside that I can't see my fingers.

In the house, the stove was boiling water, with a little steam rising from it.

There were a group of people around, some leaning on the table, some leaning on the wall, and some leaning on each other.

About ten people crowded the room, but they remained silent.

Yang Xiaotao sat at the table, also frowning.

In the afternoon, when talking about the insulation of the greenhouse, Yang Xiaotao ignored the insulation materials.

I originally thought that the village had straw fans to prevent rain, and there should also be straw blankets.

But reality slapped Yang Xiaotao hard.

The rain-proof straw fan is made of wheat straw. It's good for rain-proofing, but it's useless for keeping warm.

Therefore, the top priority now is to find a way to keep warm.

Yang Xiaotao thought in his mind that the greenhouses he had seen in his previous life were indeed made of straw blankets. He really didn't know what materials they could be made of.

Now, we can only rely on these old farmers to find a solution.

"Do you want a blanket? If every household joins in, it should be fine!"

Uncle Jiu was the first to break the silence while smoking a cigarette.

However, as soon as he finished speaking, Yang Dazhuang shook his head and said, "Xiao Tao said, there are a hundred greenhouses. Not to mention our villages, there are not so many in our town."

“And what if it’s windy and rainy?”

"This one is soaked and hard, so don't crush the film."

A few people spoke to object, but everyone fell silent again.

"Why don't we use grass? If not, we can still use reed poles!"

Fatty Ding on the side said that he heard that Yang Xiaotao was back and wanted to build a greenhouse, so he came here specially from the grain station, but he didn't expect to encounter this.

"Let's braid it with straw rope, just like corn leaves."

After the man finished speaking, someone immediately echoed, "Fat Ding is right, we can use corn stalks and fill the middle with leaves."

“Isn’t this what we used to use in coir raincoats?”

"But pull it down, the corn stalks are so thick, there won't be any air leaks if the wind blows!"

"And the reed poles are not thin either!"

"Besides, it's for heat preservation. Yours is rainproof. What's the difference between it and a straw fan?"

Someone immediately objected, and the people around nodded.

"Then what do you want to use?"

Fatty Ding asked casually, and then stopped talking.

"cough cough"

Suddenly, Lao Jin, who took the initiative to participate in the meeting, coughed twice, and everyone around him looked over.

Yang Xiaotao also looked at Lao Jin.

"Well, let me make a suggestion!"

Lao Jin met everyone's gaze and said, "I heard one thing come to mind when I heard the coir raincoat mentioned just now!"

"I don't know what the coir raincoats are made of here, but it's in the south of us. You also know that there are more people growing rice, so they use these straw poles to make coir raincoats."

"The key is, I've worn this raincoat. It's not only waterproof, but also warm..."

砰

Yang Xiaotao suddenly slapped the table, and he finally knew what the rolled-up straw blanket in his mind was.

Straw pole!

Yes, it must be right!

They are just straw poles, and then they are tied one by one with ropes and strung together to become a straw curtain.

During the day, pull it up little by little from bottom to top, and put it down at night.

"This is it, this straw curtain!"

Seeing Yang Xiaotao slamming the table in surprise, everyone was startled, but when they heard what Yang Xiaotao said, everyone felt relieved again.

Lao Jin's expression even changed, and finally he smiled.

He was finally able to help Yang Xiaotao!

It's just this way...

Forget it, other aspects are more difficult.

Yang Xiaotao looked at Yang Dazhuang now, "Uncle Dazhuang, do we have straw poles here?"

Yang Xiaotao doesn't expect to have it ready-made, but as long as there are straw poles, he can quickly make it with his hands!
Hearing this, several people around him fell silent again.

Then I heard Mr. Yang say, "There are indeed some rice farmers around Sijiu City, but not many!"

“Besides, the rice harvest was late, so we used it all to light the fire, so there probably won’t be much left!”

Yang Dazhuang added on the side, "I guess there aren't many left now!"

Yang Xiaotao calmed down and then looked at Lao Jin.

"Grandpa, there should be quite a few in the east, west and south."

After hearing this, Lao Jin thought for a moment, "There must be some!"

"The local ones are harvested every year and used to burn fires for heating. There should be stock in the ground!"

Lao Jin said, making Yang Xiaotao feel relieved.

As long as there is.

Moreover, there is Team Leader Yuan in the south to help. Just make a call and I believe he will help solve the problem!
If it doesn't work, let Mr. Huang and the others find a way. They have many ways and they will definitely be able to do it!
