Da Qin: I became friends with Zhao Zheng

Chapter 80 Chapter [-], The principles of greenhouses

"Your plan is well written, but don't ignore your health next time." Zhao Zheng said softly behind Yao Xing.

plan?Oh, the plan is not finished yet.Yao Xing wanted to walk towards the desk, but she forgot that the back of her neck was still in Zhao Zheng's hand. As soon as she took two steps forward, she was carried back.

"My plan is almost ready, I'll finish it." Yao Xing still wanted to get rid of Zhao Zheng's hand, struggling to get Zhao Zheng to let go.

"I'll finish writing the rest, so you can just wait and see." Zhao Zheng suddenly increased the strength in his hand, causing Yao Xing to utter "Ah~" in pain.

"How long have you been here?" Yao Xing thought that Zhao Zheng had been here for a long time before letting someone wake him up!
"Just arrived." Zhao Zheng said calmly.

Zhao Zheng would not lie, but would he look like a fool if he just completed the plan that had troubled him for a long time yesterday?
Sure enough, if you compare people, you will die, and if you compare goods, you will throw them away!
"Show me your plan." Yao Xing stretched out a hand towards Zhao Zheng behind him.

Yes, it was Zhao Zheng's plan. Yao Xing didn't want to admit that the plan that he had worked hard for half a night and was quickly completed by Zhao Zheng was his own, so just pretend it didn't happen!

Yao Xing just glanced at the plan and wanted to take the bamboo slip in his hand to give it to himself. How could he be so stupid?I found a greenhouse, and I thought about growing medicinal materials, but I just couldn’t think of using a greenhouse to grow medicinal materials.The investment in greenhouse farming is too big, but growing medicinal materials in greenhouses is a piece of cake!

"What is this greenhouse?" Although Zhao Zheng completed Yao Xing's plan, he was not completely familiar with the contents inside.The reason why the greenhouse was used was because Yao Xing calculated the time for the food to mature twice a year in the greenhouse on the abandoned bamboo slips nearby.

Yao Xing became interested. Look, traveling by yourself is still useful. There are things that the ancients can't match!
"It means growing medicinal materials in a house. The wall of the house is made into a double layer with pipes inside. When a fire is burned, the wall will heat up. When the temperature reaches a certain level, the growth rate of plants in winter will be the same as in summer." Mr. Yao Xing With the little knowledge I have, I will tell you the principles of the greenhouse.

"Then how to make this greenhouse?" Zhao Zheng was greatly surprised. Isn't this a way to increase food production?

"It can be made with red bricks and cement, but Mr. Su Han still needs to practice the specific details. If everything goes well, it can be built in two months." Yao Xing roughly calculated the cost of transporting the red bricks and cement and building the greenhouse. time.

"Is it feasible to use a greenhouse to grow food?" Zhao Zheng could not hide the excitement in his eyes.

But Yao Xing had to pour cold water on him: "The amount of red bricks and cement required to build a greenhouse is not small. If the entire Qin Kingdom builds greenhouses outside the land, it may take many years."

"And greenhouses need to be burned with firewood. If the entire Qin State uses firewood to heat greenhouses, where will they find firewood? A large number of trees on the mountains will decrease, which may also lead to new disasters. Maybe before the completion of greenhouses across the country , we have already thought of a better way to increase food production!"

Yao Xing could not think of the scene of greenhouse farming in the entire Qin Dynasty, and even later in the world, when later generations were studying history.

Zhao Zheng nodded thoughtfully and did not refute what Yao Xing said.

"The high beds and recliners made by Su Han have been circulated among the nobles and are highly praised. He has some talent!"
