"It's fun, it's so warm in here!" Li Muzhi and Chen Xiaoxiao, two children, secretly ran into the freshly buttoned greenhouse, playing happily and laughing non-stop. Pen & Fun & Pavilion www.biquge.info

"Don't fall!" Song Yuqin chased after her, and saw the two children running around and hurriedly shouted with concern.

"Grandma, we can't fall. Li Muyi replied as he ran.

"Ouch!" Suddenly, a stone was in front of Li Muzhi, and Li Muzhi was about to fall to the ground.

At the critical moment, Li Xuan, who was more than ten meters away, waved his hand quietly, and a true qi was held on Li Muzhi's body. Li Muzhi flipped his head in the air and stood firmly on the ground again.

"You didn't fall, did you, it scared me to death!" Song Yuqin ran to Li Muzhi in three steps and two steps, and picked up Li Muzhi.

"Giggles, that's fun! I'm going to somersault. I'm still going to play!" Li Muzhi didn't know what it meant to be afraid.

Chen Xiaoxiao followed behind Li Muzhi, showed an envious expression, and said loudly, "I'm going to turn my head too." ”

"Children's families, what to turn over, it's too dangerous!" Song Yuqin grabbed Chen Xiaoxiao, hugged Li Muzhi with one hand, and went back to the house directly.

Li Xuan's action of helping people in the void was very hidden, and no one present noticed it, and everyone only thought that it was the reason for the child's flexible body.

Li Xuan saw that his mother had taken the two children away, and turned around and continued to discuss the problem of the greenhouse with Technician Zhang. "Technician Zhang, this solar greenhouse is quite warm. But will it be so warm at night?"

"There is also a layer of cotton curtain outside this greenhouse, and at night, as long as the greenhouse is covered completely, the heat absorbed by the greenhouse during the day will not be emitted. Wait until the sun comes out the next morning and the temperature rises, then lift the curtain and continue to absorb solar energy. ”

"Oh! I see. So what if it snows the next day and the sun doesn't come out?" Li Xuan continued to ask.

"Then cover it for another day and open it when the sun comes out. Technician Zhang replied.

"What if it snows for a few days in a row?" Li Xuan looked up at the sky and felt that there would be a heavy snowfall in the next few days.

"Then cover it for a few more days, and the snow will stop. Technician Zhang replied without thinking.

"Yes. Snow doesn't always fall. But can it still be so warm in the greenhouse? All the vegetables are frozen to death. Li Xuan continued to ask. The main thing is that you can't ask this question without asking! Vegetables are very sensitive to temperature, and if they are frozen, they will be all gone.

"This, this, there should be nothing wrong, right? When I inspected and studied in Lu Province, their greenhouses were like this, and the technician said the same. Technician Zhang was asked for a moment and said with a squeak.

"Lu Province? How high is the temperature in Lu Province? At least 10 degrees higher than here in our Black Province. Besides, I've heard that it rarely snows in Lu Province!" Li Xuan finally understood why no one in Xueyuan County was willing to plant greenhouse vegetables, the temperature here in winter was too low, and there was a lot of snow, this greenhouse was not suitable for the cold of the winter in Hei Province at all, it was completely a good thing.

"Why don't we plant Rai when the temperature rises? Liu Changli interjected in time and wanted to relieve Technician Zhang.

"Then how good it would be for us to wait until spring to plant vegetables, even the greenhouse will be saved!" Song Zhong listened to the side for a long time, and finally knew that the temperature in the greenhouse was not constant, but would change according to the weather and the rotation of day and night. The climate in Hei Province in winter is so harsh, it is estimated that this dish cannot be planted, and I can't help but be a little anxious.

"Song Zhong, don't talk nonsense, let me think about it again, there should be a way to solve it!" Li Xuan looked at the ground in the greenhouse. The snow on the ground turned into snow due to the increase in the temperature in the greenhouse, which made the greenhouse a little muddy. He looked up again and saw that smoke was coming out of the smoke window of his house. It was a woman from the family who helped Li Xuan's family to light a fire and cook, preparing to entertain the villagers who came to help.

"By the way, if the temperature is not enough, you can use a fire, you can install a stove to keep warm. No, the heat dissipation of the stove is uneven, so it is better to build a fire wall in the greenhouse. Li Xuan has made up his mind. "I decided to build a fire wall in the greenhouse and keep warm when the temperature was not enough! ”

"What? You're going to build a fire wall in the greenhouse? It's not in the instructions, is that going to work?" Technician Zhang was stunned when he heard Li Xuan's words, can the greenhouse still play like this?

"The manual is dead, but the person is alive! I just read it, this greenhouse is designed according to the weather conditions of Lu Province, and the manual is also compiled for the climate of Lu Province. Since it doesn't work here in our Black Province, we have to change it. An ancient man once said that if you don't work, you will change, and if you change, you will change. Li Xuan was complacent about his creativity.

"Then it's not nice to build a fire wall in the greenhouse, and when the city comes to inspect it, it will definitely be criticized!" Technician Zhang still felt a little puzzled.

"I don't care if it's good or not! As long as it's easy to use! I built a greenhouse to grow vegetables to eat, not to meet the inspection of my superiors. After Li Xuan finished speaking, he threw down Liu Changli and Technician Zhang, and directly found his father Li Dajun, "Dad, I asked Technician Zhang from the county, the temperature in this greenhouse is not high enough in winter, and it may not be possible to grow vegetables." We can build a long wall of fire, and when it's cold, the temperature will be enough. ”

"Haha! You kid didn't go to school in vain, it's a good idea, I also think the temperature here is not high enough, and it's a bit reluctant to grow vegetables. With the wall of fire, we don't have to worry about it!" Li Dajun nodded, and went directly to someone to arrange the construction of the wall.

Li Xuan's family expanded their house in the fall, and there is still a lot of cement, sand and bricks left.

Among the dozens of villagers who came to Li Xuan's house to help, there were more than ten who knew how to mason. Those who don't know how to be masons can work as small workers, helping to make mud and move bricks.

"There is strength in numbers. Dozens of people got busy and soon built a long wall of fire inside the greenhouse, with the stove in the greenhouse and the chimney outside the greenhouse.

"It's on fire!" Song Zhong brought a large pile of wooden halberds and lit them directly in the stove.

"Ahem!" A puff of smoke came back from the stove, and Song Zhongzhi, who was choking, coughed.

"What's going on? Why does the smoke run back?" Li Xuan scratched his head, thinking that his idea had failed.

"It's okay, just wait for a while. This wall of fire is too long, and there is still moisture in it just after it is built, so it will be good to wait for this fire to push the moisture out. "The bricklayer in the village has many years of craftsmanship and is very experienced.

As he spoke, the smoke no longer came out, but a puff of black smoke with a thick damp smell came out of the chimney outside the greenhouse.

After a few minutes, the black smoke turned yellow, then blue-white, and the temperature in the greenhouse became higher and higher.

"Cousin, we made it!" When Song Zhong was crowded, he didn't dare to call Li Xuan the boss, so he could only call him "cousin".

"It worked. At this temperature, we can grow whatever we want!" Li Xuan felt the rising temperature in the greenhouse and nodded with satisfaction.

"This can also work!" Liu Changli's eyes lit up when he saw the unrecognizable greenhouse that had been changed by Li Xuan, and he felt that there was a great opportunity in front of him, and if he couldn't make good use of it, he would hold a grudge for life.
