In the same year, in the middle of winter, good news came from the experimental field of Qi Workshop, the crops in the greenhouse are growing well, and it is expected to be harvested in half a month!

What a grain grows in winter! What an amazing thing! Not only was the old farmer of the Strange Workshop shocked, but even the imperial court and even His Majesty were shocked!

In their cognition, everything grows and has a law. Winter is the time when crops wither and food is the most scarce, and at this time grain can actually be grown, and the grain is growing well, which makes these ministers surprised and delighted.

The happiest person is Li Shimin, he knows very well what it means to be able to cultivate crops in winter, which is definitely a blessing for the people!

In previous winters, I don't know how many people did not have enough food and clothing, and even froze to death and starved to death. Even if he is the king of a country, it is not easy to eat a bite of green vegetables in winter.

But now, suddenly, someone told him that he could grow food and eat it in winter, how could he not be shocked!

When he heard the news, he couldn't wait to take a group of ministers to the strange workshop to check.

To the south of the Strange Workshop, there was originally a large area of wasteland, but in recent years, these wastelands have been allocated to the Strange Workshop and used as experimental fields.

When Li Shimin's frame came to the edge of the experimental field, he lifted the curtain and looked out, and couldn't help but feel strange.

Looking out, the fields were barren and there was nothing. A little farther away, something seemed to be on the field. White, like snow, like cloth. However, Li Shimin quickly rejected the initial idea. It hasn't snowed for half a month, and for such a long time, it is absolutely impossible that there is such a large area of snow that has not melted. And the snow half a month ago was not very big, so it was impossible to pile up small bags of dirt on the field.

"Someone, go and call Chen Fei." Li Shimin stopped the carriage and horses, and ordered with a somewhat ugly face. If the news of growing grain in winter is fake, well, he doesn't recommend kicking Chen Fei into prison with one kick.

In less than half an hour, Chen Fei appeared in front of Li Shimin. Li Shimin and the ministers all looked at him with unkind faces.

"Zicheng. I heard a report from someone today that you can grow grain in the winter, but when I came here to see, why didn't there be any grain? Didn't you deceive me? ”

No food? Chen Fei was stunned, and glanced back at the greenhouse, well, the greenhouse is there, is there a supernatural event? Can't you see it?

"Your Majesty, the grain is in the greenhouse, you can't see it outside, come and take Your Majesty to have a look."

"In the greenhouse?" Li Shimin was surprised for a moment, then pointed to the white patch in the distance, and said, "That's it?" ”

"Yes, but it's warm in the big basin and the carbon dioxide concentration is high...... Ahem, the minister means that it is more stuffy inside, and it is not suitable for staying too long. “

"Well, without further ado, take me to see it!" Li Shimin was a little impatient.

Chen Fei nodded, and took Li Shimin and a group of ministers to the greenhouse.

Chen Fei's greenhouse is a bit like the kind of greenhouse basin in later generations, but it is a little different. Because there was no plastic in this era, his greenhouse was covered with ...... Silk.

That's right, the kind of silk that is very thin and can transmit light! This is only part of the story, the cost of silk is too high, and covering an acre of land makes him feel a little unbearable, so he uses glass for the rest of the greenhouse.

Chen Fei carved out five acres of land, all of which were built with glass. It was a huge project, and it took him two years to prepare for it.

Although the cost of firing glass is not high, such a large amount of glass still made the workshop work overtime for a year and a half to catch up with it.

Other technologies are simpler, nothing more than indoor temperature control, air circulation, and artificial pollination. These can be done according to the existing technical conditions.

Before Li Shimin and the others entered the glass greenhouse, they were shocked by the scene in front of them. The greenhouses covering an area of five acres are all made of glass? What a luxury!

In their eyes, glass is still a precious thing. In previous years, the value of glass was even comparable to that of jade.

Although there has been more glass circulating on the market in recent years, the value has decreased, but it is still expensive. The five acres of land are all made of glass, just to grow food...... Nima! They didn't know how to speak.

After walking into the glass greenhouse, the warm breeze blowing inside and a strange smell made everyone dizzy.

"Ahem, ahem, ahem! What does it taste like? Why does it smell so bad? Li Shimin asked while covering his mouth and nose.

"This ......" Chen Fei smiled very shyly, "Your Majesty, ministers, I'm really sorry, an hour before you came, fertilizer had just been applied in the greenhouse, and now the smell has not dissipated, so you need to be patient." ”

"Fertilization? What kind of fertilizer is applied? An old minister coughed and asked tremblingly.

Chen Fei's smile became more and more embarrassed, "That...... Of course, it is the kind of fertilizer excreted by the human body, which is the most fattenish, and it is the best choice for growing crops. ”

"Gross!" Hearing Chen Fei's words, a minister bent down and vomited on the spot.

Hey, that's it, tsk. Chen Fei shook his head regretfully, these ministers are used to being pampered, and they can't stand this taste.

On the contrary, Li Shimin is the fastest among these ministers to adapt to this smell. He quickly got used to the taste inside, and asked Chen Fei with a frown: "Zicheng, how do you maintain the temperature here?" ”

Chen Fei smiled slightly, pointed to a coal stove not far away, and said with a smile: "Back to Your Majesty, the ministers burn coal to produce heat, and put a coal stove every fifty meters." The air circulation in the shed is not good, and the natural temperature will rise over time. However, it can't be hot all the time, and the minister has made small holes in the top two rows of glass, so that the cold wind from the outside can blow in, even if the excess heat is dissipated. In this way, the temperature inside is maintained at the temperature that the grain likes, and they can grow. ”

Li Shimin looked around, and sure enough, the crops in the field were growing green, and they would be harvested in a short time.

"Then why don't you plant rice and wheat, but some fruits and vegetables?"

"Your Majesty, rice needs to be planted with water sources, it's so cold, the water introduced will freeze the rice to death, and wheat ......" Chen Fei shook his head with a smile, and spread his hands again: "Your Majesty, please see, there are only five acres of land here, and the yield of all the wheat planting will not be very large, it is better to plant some fruits and vegetables." ”

Li Shimin glanced at the greenhouse, and then Chen Fei sighed: "Zicheng, the cost of making such a piece of land is ...... Not low, right? ”

Yesterday 520, today 521, unlike yesterday, another day old, alas.
