"When the time comes, this kind of greenhouse can even be promoted across the country!"

Su Wu thought of more than these, if this greenhouse is so beneficial, then can it also ensure that the indoor temperature is higher in winter?

And even if you don't use fire and coal, you can let those poor people spend the whole winter warmly.

It's just that the cost of building such a greenhouse made of glass is expensive, and those poor people will definitely not be able to accept it.

If only there was a way to reduce the price of these glasses.

Of course, Su thought that these words were just thinking, because he had witnessed the whole process of making glass, and the manpower, material resources and coal consumed were a lot of money.

"Su Aiqing thinks very much, I also think about it, and if I can, I want to make completely transparent glass!"

Not only ordinary transparent glass, but also all kinds of plexiglass, bulletproof glass, tempered glass, he Zhu Gaojiao has to build them all.

It's just that this aspect is not what Zhu Gaoxi is involved in, he only vaguely remembers the difference between these special glasses and ordinary glasses, only the ingredients added inside, and the temperature control of smelting and solidification.

Don't worry, anyway, there is time after that, it's a big deal to try it slowly, one day, even if it is ultra-thin glass that can't be made in later generations, I can make it for you!

What is choking, technology monopoly, it doesn't exist here for him, and we also pinch their necks!

"Is it the same glass as that superb crystal?"

Isn't it the same as crystal if glass is completely transparent?

"It's not exactly the same, it's the same."

"Because crystal, glass, and glass are all made of the same substance, they are the same thing, but they are called differently!"

Is this what it looks like?

Su Wu was a little surprised, he had never heard of these things.

"Study hard, there are still many things in this world that you don't know!"

"And the knowledge you have to learn is not only the hundred schools of thought, but also astronomy and geography!"

As the saying goes, if you learn mathematics, physics and chemistry well, you are not afraid to go all over the world.

Although the current Ming Dynasty has made achievements in this area, it is completely unsystematic, and it has not been taken seriously by the world, and it has even been divided into the crooked ways of strange skills and tricks!

This is also one of the important reasons why the science and technology of China's eastern countries have widened the gap with the West in modern times!

What Zhu Gaoyi needs to do now is to change this step by step!

Otherwise, with his Zhu Gaojiao's brain, it is already the limit to be able to build muskets and cannons, as for more sophisticated aircraft, high-speed rail, rockets and missiles, and various electronic products of the modern youth of the Poison Sea, even if he wants to break his brain, he can't think of it.

"There is a precedence in hearing the Tao, there is a specialization in the art industry, I only need to govern it well, only the country is enough, and the rest is to hand it over to me the talents that continue to emerge in the Ming Dynasty!"

Zhu Gaoyao whispered.

"Your Majesty, what are you talking about?"

Su Wu seemed to have heard Zhu Gao's words just now, but he didn't hear it clearly.

"It's nothing, just sigh that the seedlings in this land, like newborn babies, are full of vitality, and under the care of the greenhouse, they will definitely thrive in the future!"

"The greenhouse researched by His Majesty naturally has such a powerful effect!"

It's just that although Zhu Gaoyi said that it was potato seedlings, what he was thinking about was the emerging talents.

"Come, come here!"

At this time, an old farmer hurriedly passed by the greenhouse where Zhu Gaoyao was.

"Your Excellency, are you calling me?"

"Is there anyone else but you?"

The old farmer looked left and right, found that there was no one around, and then decisively walked into the greenhouse.

"See my lord, I don't know if this lord called the old man here, did he want to tell the old man to do something?"

Although this old man claims to be old, his hair is only slightly gray, and if judged by his ancient appearance, this old man may only be in his forties now.

After all, the elderly in ancient China's rural society, once they reached the age of 50, or even reached the age of 60, could only wait at home to die.

On weekdays, he became ill from hard work, and when he got older, he quickly manifested himself.

"Let me ask you, how many acres of potatoes have been planted here?"

Su Wu asked Zhu Gao's question,

"My lord, you are asking the right person, you see more than a dozen greenhouses around here, but they are all old, and there are people under the old man to take care of them together!"

"Each greenhouse covers an area of half an acre, but only a part of it can be used to grow potatoes, which is equivalent to one acre of land for about three greenhouses, and there are fifteen greenhouses here, so there are a total of five acres of potatoes!"

Five acres of land, which is already a lot.

After hearing this, Zhu Gaoyi didn't dare to be surprised, because these potatoes were found in those boxes that were poured into seawater.

There is no guarantee of the germination rate of those potatoes, and even if all of them can germinate, it is difficult to grow such a large area.

"You guys, this is a cutting?"

Zhu Gaoyao hurriedly peeled open the ground below, and found that there were no lumps of potatoes underneath, but some small rhizomes that had just begun to grow.

"Yo, this adult, I Guanyin is extraordinary, I look like a big official, I didn't expect to be proficient in agriculture!"

Officials who are proficient in agriculture and mulberry are often very close to the people, but this is a word from the older generation, and the old man looked at Zhu Gao's gaze, and suddenly became a lot more cordial.

It's just that Zhu Gaoyao saw this, but his brows furrowed slightly.

Although the potatoes planted in this way can be planted in the spring of next year, the potato pieces will be very small, even if the whole potato is planted, it will be difficult to get a large potato in the spring of the next year!

This will undoubtedly be bigger, and the yield will be greatly reduced, and the potatoes produced by the rhizomes of those potato seedlings that have broken off their stems will be much smaller than normal.

In this way, the number of seeds that can be produced will be greatly increased in a short period of time, but the yield for the next year will be greatly reduced!

Even if more land is used to grow potatoes, the overall yield will drop significantly.

Su Wu saw that Zhu Gao's face changed, and he immediately sensed that something was wrong.

"But do you know that although this cuttings can speed up the number of potato seedlings, it will greatly reduce their yield!"

At this time, the old farmer didn't seem to understand what Zhu Gaojiao was talking about.

"How could this be? If you think about it, the number of these seedlings has increased, and even if one plant is a little less, its yield will at least increase several times! (End of chapter)
