Traveling through Great Qin: Father Qin Shihuang!

"Che'er, where is your greenhouse? Take me to see it quickly. If this product can be promoted, won't my Daqin have no shortage of fresh vegetables all year round in the future?"

Ying Zheng sighed.

Generally speaking, in winter, vegetables are the most precious. Even if he is the Emperor of Great Qin, he can only eat those vegetables stored in the cellar.

Fresh vegetables do not mean whether you have the money to buy them, but that no matter how much money you spend, you cannot buy them.

Even those vegetables that have been stored for a long time are expensive on the market, much more expensive than meat.

In a blink of an eye, Zhao Che had already led Ying Zheng and the others out, and arrived at a remote suburb in a carriage.

There are only dozens of huge tents built here, and the tents are covered with thatch, which should be to keep out the cold.

"This is the greenhouse!"

"The greenhouse you mentioned is a tent? Can you grow vegetables in a tent?"

Ying Zheng didn't quite understand, and pointed to the tent in front of him curiously.

"Greenhouses are actually a way to adjust the temperature and humidity inside by artificial means to simulate the growing season of plants. The real greenhouses are actually even more powerful than this, but now the conditions are limited and we can only use cloth tents. instead."

Zhao Che spread his hands, he has not yet obtained the production technology of plastic, even if he obtained it, with the current relevant technical means, it would not be able to produce it at all.

Fortunately, although the cloth tent is more troublesome, it can also simulate the effect of a greenhouse. In order to maintain sufficient sunlight, Zhao Che also installed glass on the top of the tent, and replaced the ultraviolet lamp with a permanent lamp. Effect.

"Can we go in and have a look?"

"No problem at all!"

Zhao Che pushed open the door of the shed and walked in with Ying Zheng and Meng Yi.

"This this this..."

As soon as Yingzheng came in, he saw a lush plant, including all kinds of vegetables and fruits, which obviously had just reached maturity, and some were even still growing.

"It's so hot in this greenhouse, it feels like summer, why are there so many lights here?"

Meng Yi was wearing thick clothes, and dense sweat appeared on his forehead within a few minutes after entering.

"The greenhouse is originally designed to simulate the warm season environment, of course it will be hot, and these lights are responsible for adjusting the indoor temperature."

"I see!"

Ying Zheng nodded, and already had a little understanding of how the greenhouse works.

"However, there are so many lamps in this shed, and it needs to be lit every day. Doesn't it cost a lot of oil? I'm afraid the cost is not low?"

Ying Zheng stroked the beard on his chin and said while looking at the dense rows of ever-burning lights in front of him.

"Of course not. These lamps are different from the ones you use. The main reason is that the lamp oil not only burns very stably, but also burns relatively slowly, and the cost is also very low."

"Oh? In order to grow vegetables, you still made such a special lamp oil?"

"No way, the requirements for the growing environment of vegetables are relatively harsh."

Zhao Che spread his hands and said.

"Young master, is this lamp oil easy to get? Can it be produced on a large scale? If it is popularized, wouldn't it be able to replace the oil lamps we use now?"

Meng Yi was really interested in everything he saw, and after a while, he thought about how to get the lamp oil away.

"This lamp is not suitable for home use, mainly because the brightness is too low. There are better candles for home use."

"Candle?"

"It's also a lamp made of grease, but it's solid, easy to carry, and brighter."

"Is there such a good thing? Why haven't I seen you take it out before?"

Ying Zheng stroked his beard and asked.

"It's always been there, it's just that you haven't used it."

"Not used?"

Ying Zheng thought about it carefully, as if he really hadn't used it, after all, every time he came over, he basically went back very early.

Occasionally, he spent two nights here with Zhao Che, but he was either drunk or sick.

"Let's talk about this greenhouse first. What kind of fruit is this? The bright red ones are really pretty!"

Ying Zheng walked to the tomato shelf, looking at the bright red apple-like thing very curiously.

"This thing is called a tomato, or it can be called a tomato. It can be regarded as a vegetable. It can be eaten raw or cooked."

Zhao Che also got tomatoes recently, and the first batch that was planted just came out.

"Can it be eaten raw? I'll try it!"

Ying Zheng picked off a large and red tomato, wiped it on his clothes, and put it in his mouth.

"Well... it's sweet and sour, it tastes really good!"

Ying Zheng had just finished eating the tomato when he stared at the banana tree next to him.

"This is plantain? Isn't this something that can only grow in Baiyue? You can grow it here too?"

"Of course. In theory, a greenhouse can simulate any environment. The hot and humid climate in the south can also be simulated naturally, so anything can be planted."

"Good thing, this greenhouse must be popularized. In the future, we will be able to eat fresh vegetables and fruits in Guizhou all over the world in winter. This is a great thing that benefits the country and the people."

Ying Zheng clapped his hands. Having seen the magic of greenhouses, he wished he could build them all over the country now.

"You can try it later, Dad, but it's not enough just to build a greenhouse. The most important thing is how to control the temperature inside, and to understand the growth habits of various crops, so that they can be cultivated better."

"Yes, you can give me the construction method of this greenhouse later, and I will send someone to build it immediately when I go back."

"Well, the living habits of these crops are actually recorded in detail in the field law, and you can also let people learn it."

Zhao Che gave a warning, and then returned to the mansion with Ying Zheng and others.

"Che'er, what about the candle you mentioned earlier that can be used for lighting? Quickly take it out and let me see it!"

As soon as Ying Zheng came back, he asked about the candle again.

"Maverick, go get some candles!"

Zhao Che casually ordered, and Maverick walked over with a bundle of red candles after a while.

"Is this thing better than an oil lamp?"

Faced with Ying Zheng's doubts, Zhao Che did not explain, but picked up a box of matches and lit a candle.

Immediately, a small flame appeared on the candle head, emitting a faint light, and the brightness was obviously much brighter than that of an oil lamp.

"This candle can also be made into a lantern, so it is much more convenient to carry it when walking at night."

As Zhao Che said, he brought a portable lantern from somewhere, and put the candle in it.

"Okay! This candle is indeed a good thing. I must build a factory to produce this. It is much more useful than oil lamps."

Ying Zheng clapped his hands and made a decision.

"Of course, I will give you the recipe for the candle in a while. The cost of this candle is very low. Compared with oil lamps, it is naturally much cheaper."

"Okay, I'll go back to Xianyang and explain this matter to you!"

Ying Zheng originally planned to take a few days of annual leave, but now that he has such a good thing, he naturally needs to pass it on as soon as possible to make preparations, so he decisively canceled the holiday.

"How to make candles, as well as how to build and make a greenhouse, are all here!"

Zhao Che dug out two pamphlets and handed them to Ying Zheng.

"Then let's go first, and I'll come back after this matter is explained!"

Ying Zheng couldn't wait any longer, he greeted Zhao Che, took Meng Yi into the carriage, and headed for Xianyang.
