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

Chapter 10

[End of break.] 】

[Continue to popularize science.] 】

[The ten crops that have made the greatest contribution to mankind in popular science!].

[Eighth place: sorghum.] 】

Sorghum is an annual tall herbaceous plant of the genus Poaceae. 】

The characteristics are as follows:

[The height of the stalk is very different, stout, erect, and the base node has supporting roots. 】

[Leaves are broad and long, leaf sheaths glabrous or slightly white-powdered; leaf tongue dura, apex rounded, margins ciliated; leaves linear to linear-lanceolate, base round or slightly ear-shaped, surface dark green; panicles are loose; both spikes are leathery, the fruit is flat and convex on both sides, yellow-green at first, dark brown after maturity; the columella is separated, and the stigma is broom-shaped. 】

[Its flowering and fruiting period is June ~ September. 】

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

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

Anyway, I can't understand how to explain it.

He directly and thoughtfully put a picture of sorghum.

[Sorghum originated in Heizhou and was introduced to China from the Three Kingdoms of Argentina. 】

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

[Sorghum is a temperature-loving crop, with strong adaptability, both drought resistance and waterlogging resistance, so the cutting and cultivation area is wide. 】

[Special Attention:].

[Sorghum is afraid of frost damage, early sowing in spring, when the minimum ground temperature reaches -3 °C (note: the temperature is 0 °C when freezing) the plant will die. 】

[Seedlings are the most sensitive to light, so if the sorghum varieties planted in the north of China are planted in the south, the growth period will be shortened: the growth period will be extended if the southern varieties are planted in the north. 】

[Sorghum has a reputation in "Food Materia Medica" as "the essence of the five symbols and the length of a hundred grains". 】

Sorghum is rich in a variety of nutrients, mainly used for brewing, making food, and feed for livestock. 】

【......】

Qin Dynasty.

Ying Zheng looked at the popular science of the light curtain in a daze.

He muttered, "What kind of place is Heizhou, why haven't you heard of it?"

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

"Yes, the expansion of Great Qin's territory is to see how vast this world is. "

Ying Zheng quickly stabilized his mind.

Wait for the people of Daqin to recuperate for a period of time.

He was going to expand his territory to the south.

I wonder if I can find the black state?

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

Why is that continent called the Black State?

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

Read on.

He was shocked again.

"Three thousand years ago..."

"Could this thing be from the Hereafter?"

Ying Zheng deduced the true answer from the popular science content.

"It's a good idea to freeze at 0°C, so that you can check the weather. "

His brain was racing.

Quickly sort out a feasible national policy.

Unify the 0°C ice into the measurement row, the higher the number, the hotter the weather, and the lower the number, the colder the weather.

......

Han dynasty.

Liu Bang personally went into battle this time.

Take a pen and record it yourself.

A good memory is better than a bad pen.

He didn't believe he could forget what he had seen if he copied it once.

This time, you will get a reward for saying anything.

"Your Majesty Shengming!".

The emperor took it upon himself to copy it.

The civil servants below worked hard to write like chicken blood.

The generals stared at the light curtain with a pair of bronze bell-like eyes.

As soon as there is a window to answer, immediately shout to remind His Majesty to answer.

.........

Shu.

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

How can I surpass the emperors of other dynasties?

He considered himself to be far inferior to the founding emperors of the dynasties.

Emperor Yingzheng of Qin, and Zhu Yuanzhang.

He's certainly not comparable.

Liu Chan's eyes swirled in his sockets.

He quickly came up with an excellent idea.

Since you can't rely on yourself, then change to a powerful person.

Liu Chan stared at Zhuge Liang with burning eyes, and his tone was unprecedentedly serious.

"Father, I know that I can't compare to Emperor Qin's reign, ask Father Xiang to help me!".

Zhuge Liang: "...."

???

He was confused.

The minister has been helping you, but this is for the sake of the emperor's face.

He told me to stand on my own feet, and I didn't even say yes.

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

"Father, I won't hide it from you, I have a brilliant idea, Father Xiang knows the answer and immediately tells me, and I will answer, maybe there will be a chance to continue the national fortune for Shu. "

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

You're such a clever ghost.

He was speechless for a moment.

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

Zhuge Liang sighed.

He's an old bone, and he has to continue to struggle.

.........

Tang dynasty.

Following the eldest grandson Wuji, Wei Zheng, Fang Xuanling, Cheng Yanjin and others arrived.

Li Shimin didn't expect it.

One day his imperial garden can be so lively.

Most of the famous ministers of the Tang Dynasty gathered here.

"Your Majesty!".

Li Shimin looked at dozens of ministers, and there was no way to arrange a seat.

"I'm tired of you standing with me. "

Cheng Biting Jin's heart was straightforward, and replied loudly: "Your Majesty, what's the point of standing for a while, others can sit on the ground if they want to." "

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

Wei Zheng stroked his beard and said directly: "You guy, if you want to sit on the ground, you can say it directly, and Your Majesty will not blame you." "

"Old horseman, you can't !? fight".

Cheng Biting Jin has a hot temper, where is he used to him.

"Alright, alright. "Li Shimin came out to play a round," you guys watch the popular science video first, and if you want to fight or fight and leave the palace, I don't ask. "

The two glared at each other and did not continue to speak.

Li Shimin looked at the light curtain and asked

"Heizhou?Could it be Kunlunnu's hometown?".

He remembered a kind of black-skinned foreign slave, simple-minded but strong-bodied.

Perfect for being a slave and doing some heavy lifting.

Picking cotton is also a good hand.

After pondering, Fang Xuanling replied: "Your Majesty, it should be, and the minister will inquire later." "

[No surprises!].

[Rush to answer the question!].

[Where does sorghum come from?].

[Option 1: Black State].

[Option 2: Huaxia].
