Chapter 1533. What to use for insulation?
After lunch, Ran Qiuye and other women returned the same way with baskets and wooden barrels to clean up their homes.
The men rested for a while and continued to work.
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 frame and put on the film!”
Yang Xiaotao said from the side. Although the greenhouse in front of him was a bit rough, this was the fastest speed.
The most important thing is that it does not affect the use.
On the side, Lao Jin and his grandfather were sitting on the cart talking.
“I haven’t worked for a long time, and it hurts when I do it!”
Lao Jin rubbed his arms and sighed. Although he is three years younger than Mr. Yang, he can still work hard. Come on, I really can’t keep up with the 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 that 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 after living here for a long time."
"I used to live here. Even cotton-padded jackets require hard work. Now that life is better, children can run in the snow. ”
"Yeah, compared to before, it's better now!"
Lao Jin sighed with emotion while holding a cigarette in his mouth.
"When you have time to go to Shanghai, I will take you on a boat trip on the Huangpu River~"
Mr. Yang smiled, "I have been to the Yangtze River, but not in Shanghai. At that time I followed the boat to Jinling..."
Hearing this, Lao Jin laughed and said, "I forgot about it, but Shanghai is much better now than before, and there are all kinds of good things!"
After hearing this, Mr. Yang clicked 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, even though 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 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 was just like a greenhouse in the past! Our country has been around 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 sighed, "In the past, the princes and nobles would have people build a greenhouse in order to satisfy their appetites in the winter."
“This thing is not simple. It requires not only dedicated people to take care of it, but also specialized technology. A greenhouse consumes more supplies than ordinary people in a year.”
“It’s as hot as spring, which is perfect for growing vegetables and fruits.”
“But that’s only for the upper class. It’s a waste of money and people, but it would be nice if the people below could have firewood to burn it.”
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 was all excited. He nodded, and at the same time, he 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 did not dare to be careless, and followed each other to listen.
“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 of great use, not only to meet the needs of Transmittance, but also strong , it can’t be broken with just one poke, but also..."
Yang Xiaotao said, and Yang Shitou beside him 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 opening its mouth.
The price has increased tenfold!
If the country had not earned a lot of foreign exchange during this period, and the herb was in urgent need, the higher-ups would not 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 carry out research and development, and it will be ready in a short time.”
“But we are in a hurry to use it this time, and the scale is so large, so we will buy it from the alliance first. Let’s use it for emergencies. Don’t worry, we will have our own film in the future.”
When Yang Xiaotao said this, 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 built, they could still imagine it. What to do.
“You must also pay attention to the temperature at night. It must be controlled well. It cannot be too cold. If it is too cold, the seedlings inside will freeze to death.”
“So the soil used in the greenhouse must be It is 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, a group of 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 falling behind him, suddenly He muttered, "It's so cold at night, how much firewood do we have to burn!"
Yang Xiaotao was walking in front. After hearing this, he immediately laughed and said, "Actually, it won't take much, just put a blanket on the film!"
"What blanket?"
< br>On the side, Yang Dazhuang suddenly spoke, with a complicated expression on his face.
Yang Xiaotao was also suddenly stunned, and then looked at Yang Dazhuang, "Uncle Dazhuang, there are 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.
A group of people were surrounding, some leaning on the table, some leaning on the wall, and some leaning on each other.
About a dozen 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 rainproof grass fan is made of wheat straw. It is good for rainproofing, but it is useless for heat preservation.
So, 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? It should be okay if every household joins together!"
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, even our town does not have so many."
< br>
"And what if it's windy and rainy?"
"This one is soaked and hard, so don't crush the film."
A few people objected, and everyone again silence.
"Why don't we use grass? If not, we still have reed poles!"
Fatty Ding on the side said. He heard that Yang Xiaotao was back and wanted to build a greenhouse, so he specially came from the grain station. I rushed over, but I didn't expect to encounter this.
"Let's braid it with straw rope, just like corn leaves."
After the man said this, someone immediately echoed, "Fat Ding is right, we can use corn stalks and fill the middle with leaves. "
" We used to use this for our coir raincoats!”
“But pull them down, the corn stalks are so thick, there won’t be any air leaks if the wind blows!”
“There are also reed poles, Not too thin!”
"Besides, this is for heat preservation. Yours is rainproof. How is it different from a straw fan!"
Some people immediately objected, and the people around them nodded.
"What do you want to use?"
Fatty Ding asked casually, and then stopped talking.
“Ahem”
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 said in front of everyone’s eyes, “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 have worn this raincoat. It is not only waterproof, but also warm..."
Bang
Yang Xiaotao suddenly slapped the table, and finally knew that the rolled straw blanket in his mind was What's up?
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.
Pull it up little by little from bottom to top during the day, and put it down at night.
“This is it, this straw curtain!”
Seeing Yang Xiaotao slapping the table in surprise, everyone was startled, but when they heard what Yang Xiaotao said, everyone felt relieved.
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 at this moment, "Uncle Dazhuang, do we have straw poles here?"
Yang Xiaotao didn't expect to have ready-made straw poles, but as long as there are straw poles, he can mobilize people. Make it quickly!
Hearing this, several people around him fell silent again.
Then I heard Mr. Yang say, "There are indeed some rice growers around Sijiu City, but not many!"
"Besides, the rice harvest was late, so they all used it to make fires. I guess There aren’t many left!”
Yang Dazhuang added, “I guess there isn’t much left now!”
Yang Xiaotao calmed down and looked at Lao Jin.
"Grandpa, there should be a lot of them in the east, west and south."
After hearing this, Lao Jin thought for a moment, "There must be some!"
"The local harvest is used every year. Make a fire to keep warm, there should be something 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!
