There was no greenhouse effect in ancient times, so what's the use of telling these ancient people? No one will understand what this means, modern factories emit a lot of exhaust gases, and the exhaust emissions of vehicles increase the concentration of carbon dioxide, which in turn warms the weather.

Although it is late autumn at the moment, the coolness cannot be dispelled.

Li Jian didn't understand why Zhou Zheng did this, but Zhou Zheng decided to do this, even though he was a craftsman leader who hung up the position of an official under the big boss, he always belonged to the low-level officials, and the orders above dared to have different opinions, and if he offended the above official position, it might be gone, so Zhou Zheng didn't tell Li Jian the reason for doing this, and Li Arm didn't ask anymore.

The first greenhouse is currently looking at Zhou, has been completed, a large number of sunny places are all inlaid with glass, at this moment the sunlight shines in from outside the glass to make people a little dazzling, need to adapt to a period of time to completely break open the eyes, otherwise just into the greenhouse inside the dazzling sunlight through the glass only squint to see, if these sunlight is not outside with the eyes directly to the sun that extremely dazzling feeling, but looking at a long time will inevitably make people's eyesight decline.

After staying in the greenhouse for a while, a warmth suddenly rose from Zhou Zheng's heart, at first it was only slightly warm, as if suddenly encountering a burning flame in this cold late autumn, Zhou Zheng felt a sense of heat rising from his heart for a while, and the clothes on his body seemed to be redundant, and he couldn't wait to reduce the clothes by one or two, at this time Zhou Zheng knew that the glass had begun to play a role.

Li Jian also felt these warmth in the group, but after the greenhouse was built, in addition to the craftsmen below who came in to install the glass, he did not come in, this time he entered the greenhouse in the same week, or Li Jian entered it for the first time, and after a long time, the feeling of dryness and heat rose in Li Jian's heart, and he immediately understood why those craftsmen took off most of their clothes when they were installing glass yesterday, and thought it was the reason for the long dry time, but now I understand the role of these glasses.

"Your Highness, this conservatory is really magical, at the beginning it was just a little warm, the longer the temperature inside is, if the sun shines for a long time, I am afraid that the weather in this conservatory will be the same as midsummer!" Saying that, Li Jian looked at these glasses, obviously Li Jian also realized that the increase in temperature in the greenhouse had a lot to do with these glasses.

However, Zhou Zheng didn't care that Li Jian knew this role of glass, and he was not afraid that Li Jian would publicize it, so what if Li Jian knew that glass had such a role?

First of all, the production method of glass has always been a mystery of the royal family, although Zhou Zheng himself knows how the glass is fired, but it will not be revealed in this way, even if someone gets the glass from Li Jian can be used to build a greenhouse and greatly increase the temperature in the greenhouse, but don't forget that the role of glass is only useful when the sun appears, and the greenhouse will be abandoned without the sun, and it will not play any role in keeping warm and heating at all.

Not to mention that the sun sets at night, it is also a very big problem to retain the temperature in the greenhouse, in the era when no one knows what the greenhouse effect is, Zhou Zheng's simple knowledge plus some small means can naturally prevent the temperature in the greenhouse from dropping sharply at night.

"How does Li Gong feel about this conservatory now, is it very hot?" Although it was a little hot, Zhou Zheng couldn't help but show off to Li Jian.

"Only the word magic can be explained." In the eyes of modern people, this is just a very simple scientific phenomenon, which is not enough to worry about, in ancient society, it is not the same, do not rely on the burning of charcoal fire, let the temperature in the greenhouse continue to rise out of thin air, such a magical phenomenon, people who don't know still think it is a fairy law, and Li Arm, the craftsman, probably understands the role of glass, but for what reason Li Arm does not know.

"By the way, Li Gong, since this greenhouse has been built, and then help this king collect a large amount of straw after the autumn harvest, this king will be of great use." Looking at the sunlight shining in, Zhou Zheng didn't know what to think of and commanded Li Jian.

Now that the autumn harvest has just passed, some late-maturing places have not yet harvested rice, naturally there is a large amount of straw, although Li Jian does not know what Zhou Zheng wants a large amount of straw for, but it does not prevent Li Jian from collecting straw Anyway, now the field is full of straw, easy to get, collecting some will not waste too much time.

After ordering this, Zhou Zheng only stayed in the greenhouse for a very short time before leaving the greenhouse, staying in the greenhouse for a long time will only get hotter and hotter, and the hot Zhou Zheng really couldn't bear it and left the greenhouse with Li Jian and others, and came to the door of the greenhouse.

Standing at the door of the conservatory, a refreshing cold wind blew, forming a huge contrast, just a door apart in the conservatory incomparably warm and even warm, a little like summer, but when you come to the door, it is like a change of season, which makes people wonder if what happened just now is an illusion.

The first greenhouse has been built, Zhou Zheng has to face the idea of what vegetables should be planted, as early as the previous construction of the greenhouse Zhou Zheng considered this problem, the first thing that came to mind is that green vegetables can be eaten in winter is a luxury, especially in the hot pot green vegetables are a necessary vegetable.

Nowadays, hot pot is becoming more and more popular in Hokyo, and it has become popular to eat a spicy and piping hot pot when the weather turns cooler, and it is bound to make a fortune by providing vegetables in winter.

There is also the green onion, "King Huan five years, the Northern Expedition to the mountains, get the winter onion, cloth the world." "In the fifth year of the reign of King Huan of Zhou, Zhou Zheng's grandfather, the Northern Expedition Rong tribe, obtained winter onions in a tribe in the north and then planted them in the Great Zhou, so Zhou Zheng decided to plant green onions after the greenhouse was built.

The last vegetable chooses leeks, leeks like cold and cool, not only cold and heat resistant, the seed germination temperature is more than 12 °C, the growth temperature is 15 °C to 25 °C, and the underground can tolerate lower temperatures, so the vegetables are planted in the greenhouse.

Now there is a greenhouse, and the three vegetables that have been decided before can also be planted, and Zhou Zheng immediately said to Xu Fei: "Xu Fei, go and recruit a group of farmers in the afternoon to reclaim the land in the greenhouse." Zhou Zheng didn't say why he wanted to reclaim the land, and Xu Fei also knew what Zhou Zheng was doing here.

It was a conservatory and land reclamation, clearly telling others that he was going to plant trees and things, and then Xu Fei also replied, promising that the land in the conservatory would be reclaimed before evening.
