I make a popular science video and all the emperors learn from it!

【Rest time is over】

【Continue to popularize science】

【The ten crops with the greatest scientific contribution to mankind!】

【Eighth place: Sorghum】

【Sorghum is an annual tall herbaceous plant of the Gramineae family.】

【The characteristics are as follows:】

【The height of the stalk is very different, thick and upright, with supporting roots on the base node.】

【The leaves are broad and long, the leaf sheaths are hairless or slightly white; the ligule is membranous, with a rounded apex and ciliated edges; the leaves are linear to linear-lanceolate, with a round or slightly ear-shaped base and a dark green surface; the panicles are loose. ; Both caryopses are leathery, and both sides of the caryopses are flat and convex, yellow-green at first and dark brown when mature; styles are separated and stigmas are broom-shaped.】

【Its flowering and fruiting period is from June to September. 】

When Chen Yu made the popular science video, he did not completely use modern vernacular.

Some popular science content that is not easy to describe is simply copied and pasted.

Anyway, I can’t understand it no matter how I explain it.

He directly and thoughtfully posted a picture of sorghum

【Sorghum is native to Heizhou and was introduced to China from the Asan Kingdom.】

【As early as 3,000 years ago, there was a history of cultivating sorghum in the Yellow River Basin of China.】

【Sorghum is a temperature-loving crop with strong adaptability and resistance to both drought and floods, so it has a wide cultivation area.】

【pay attention:】

【Sorghum is afraid of frost damage, so it should be sown early and at the right time in spring. When the lowest temperature on the ground reaches -3℃ (note: the temperature is 0℃ during freezing) the plants will die.】

【Seedlings are most sensitive to light, so when sorghum varieties from northern China are planted in the south, the growth period will be shortened; when southern varieties are planted in the north, the growth period will be extended.】

【Sorghum has the reputation of"the essence of five talismans and the growth of hundreds of grains" in"Food Materia Medica"】

【Sorghum is rich in various nutrients and is mainly used for wine making, food making, and livestock feed.】

【......】

Qin Dynasty.

Ying Zheng stared blankly at the light screen's popular science.

He murmured:"What kind of place is Heizhou? Why haven't you heard of it?"

At this time, Li Si explained:"Your Majesty, Heizhou should be a continent far away from the Qin Dynasty."

"That's right, I want to expand the territory of Great Qin just to see how vast this world is."

Ying Zheng quickly calmed down.

After the people of Great Qin recuperated for a while, he planned to expand the territory southward.

I wonder if he can find Heizhou?

At the same time, a question came to his mind.

Why is that continent called Heizhou?

Could it be that the people there were all pitch black?

Continue looking down.

He was shocked again

"three thousand years ago..."

"Could this thing come from later generations?"

Ying Zheng guessed the real answer from the popular science content.

"It freezes at 0°C. This is a good way to check the weather."

His brain was working quickly. He quickly sorted out a feasible national policy.

Unify 0℃ freezing into the measurement line. The larger the number, the hotter the weather, and the lower the temperature, the colder the weather.......

Han Dynasty.

Liu Bang went into battle in person this time.

Get yourself a pen to record.

A good memory is worse than a bad pen.

He didn't believe that he could forget what he saw if he copied it once.

No matter what I do this time, I will get a reward.

"Your majesty is wise!"

The emperor personally copied the excerpts.

The civil servants below were writing as fast as chicken blood.

The generals stared at the light screen with a pair of copper bell-like eyes.

Once the window for answering appeared, they immediately shouted to remind His Majesty answered.........

Shu Kingdom.

Liu Chan drove away the servants around him to prevent them from disturbing him.

How can one surpass the emperors of other dynasties?

He believed that he was far inferior to the founding emperors of various dynasties.

Emperor Qin Yingzheng, and Zhu Yuanzhang.

He definitely can't compare.

Liu Chan's eyes rolled in his sockets.

He quickly thought of an excellent solution.

Since you can't do it on your own, find someone powerful.

Liu Chan stared at Zhuge Liang with burning eyes and his tone was more serious than ever.

"My dear, I know that I cannot match the Qin Emperor Yingzheng, so please help me!"

Zhuge Liang:"...."

???

He was confused.

I have been helping you for the sake of the late emperor.

He asked me to be independent, but I didn't agree.

Seeing that Zhuge Liang didn't understand his thoughts, Liu Chan got straight to the point:

"Xiangfu! I won’t hide it from you. I have a brilliant idea. If my husband knows the answer, he will tell me immediately. I will answer it. Maybe there will be a chance to continue the destiny of the country of Shu."

"......."Zhuge Liang.

You are such a clever guy.

He was speechless for a moment.

I have to admit that this is indeed the most reliable method at present.

Zhuge Liang sighed.

He has such an old bone, he still has to keep fighting..........

Tang Dynasty.

Following Changsun Wuji, Wei Zheng, Fang Xuanling, Cheng Yaojin and others arrived.

Li Shimin didn't expect it either.

One day his imperial garden could be so lively.

Most of the famous officials of the Tang Dynasty gathered here

"His Majesty!"

Li Shimin looked at dozens of ministers and couldn't arrange their seats.

"Could you please stand with me? Cheng

Yaojin spoke bluntly and replied loudly:"Your Majesty, it doesn't matter if you stand for a while. Others can sit on the ground if they want.""

As soon as these words came out, the civil servants were unhappy.

Wei Zheng stroked his beard and retorted directly:"You guys, if you want to sit on the ground, you can just say so, and your Majesty will not blame you."

"You old man, you can't beat me!! ?"

Cheng Yaojin has a hot temper, how can he be spoiled?

"OK OK. Li Shimin came out to smooth things over,"Everyone, please watch the popular science video first. If you want to fight or leave the palace in a fight, I won't ask.""

The two glared at each other and did not continue talking.

Li Shimin looked at the light curtain and asked around:

"Black State? Could it be Kunlun Nu’s hometown?"

He remembered that there was a kind of foreign slave with dark skin. Although he had a simple mind, he had a strong body. He was very suitable for being a slave and doing some heavy work.

He was also good at picking cotton.

After thinking deeply, Fang Xuanling replied:" Your Majesty, it should be so. I will ask about it later."

【No surprise!】

【Q&A session!】

【Where does sorghum come from?】

【Option 1: Black State】

【Option 2: Huaxia】

【Option three: I don’t know】

【Option 4: Mars]

Li Shimin’s eyes lit up!

What's the difference between this and someone giving you a pillow when you're sleepy?
