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

Han Dynasty.

Liu Bang no longer knew what to say.

Throughout his life, he can be called the chosen one.

When he was young, he would fool around with his brothers every day, and he could even become the daughter of a rich family.

When he was about to be buried, Ying Zheng died and the world was in chaos.

He just took the opportunity to rebel.

Directly picked up two top talents, Xiao He and Han Xin.

But compared with the Americas, why are their fortunes better there!

It’s more like being blessed by God.............................

Shu Kingdom.

Liu Chan sat upright, his eyes always staring at the light screen.

But I keep recalling the sweet taste of popcorn in my mind

‘I want to eat popcorn’

‘Give me some popcorn! '

Next time during the Q&A session, if you answer incorrectly, you will be given a bucket of popcorn as a gift.

Liu Chan's absent-minded state was clearly visible to Zhuge Liang.

Zhuge Liang looked at the sky melancholy..................................

Tang Dynasty.

Li Shimin was numb.

Why are all the good things happening to America?! ?

"Post a notice all over the country, let me check if anyone has heard of where America is?"

Li Shimin immediately issued an imperial edict.

Song Dynasty.

Zhao Kuangyin murmured to himself:"I should establish an empire in America."....................................

【Popular science continues】

【The artificial cultivation of potatoes can be traced back to about 8000 BC to 5000 BC. Potatoes around the world originated from potatoes grown in the southern region of Peru, from where they gradually spread to the north and south of South America. With the Spanish conquest of the Inca Empire, potatoes were brought back to Europe by the Spanish in the second half of the 16th century and spread.】

【Then they were taken to all parts of the world by European explorers and colonists】

【The time when it was introduced to China was probably during the Wanli period of the Ming Dynasty in the 16th century.】

【......】

Ming Dynasty.

Zhu Yuanzhang was very excited

"Potatoes are also in our tomorrow!"

"Wanli period...."

"Which of Biao'er's descendants created the reign name?"

When he saw the potato yield per acre, he wanted to take it into his pocket.

It's a pity that potatoes were not introduced during the Hongwu period.

At this time, even if he searched across the country, he probably wouldn't be able to find them.

But how can he get potatoes?

Zhu Yuanzhang felt anxious in his heart.

Suddenly, a pop-up window appeared on the light screen.

【Q&A session!】

【Which of the following names is not another name for potato?】

【Option 1: Potatoes】

【Option 2: Dutch potatoes】

【Option 3: Ground Egg】

【Option 4: Yam beans】

【Option five: Yang taro】

【Option 6: Yam cubes]

Just in time!

Zhu Yuanzhang took the initiative to approve the memorial.

Seeing six options, he was immediately confused.

What's going on? Why do you feel like you've seen every one of them in popular science videos? time does not wait.

If you take a step slowly, others will take away the reward!

Zhu Yuanzhang faced the light screen and shouted:"Option 1!"

He clearly remembered that the first nickname for potatoes was potato.

【wrong answer!】

【Congratulations to Qin Dynasty Yingzheng for successfully answering the question】

【Get 1,000 pounds of potatoes. 】!!!

Zhu Yuanzhang was so tortured that his head was full of paste.

His answer is absolutely correct!

Potato is another name for potato.

At this time, Empress Ma came over to comfort her:"Chongba, please look carefully. Which one is not another name for potato? I didn't ask you to choose the correct answer."

At first, she also saw which option was the correct answer.

Until Zhu Yuanzhang answered wrongly.

She read the question carefully again and discovered the mystery.

When Zhu Yuanzhang heard this, he took another look with wide eyes.

I found out that’s really the case!

"ah! We were fooled."

Zhu Yuanzhang regretted it too much.

But he didn't dare to get angry at the light screen, he could only sulk.

Well, now the only chance to get potatoes is gone.

Is there any other way?

Zhu Yuanzhang's brain was working quickly.

Soon, he suddenly woke up

"Potatoes came from overseas. Why don't we go overseas to look for them?"

After thinking about it, a bigger problem lies ahead.

The Ming Dynasty has a sea ban.

And it was just issued a few years ago.

Do you want him to break the sea ban he made now?.............................................

Qin Dynasty

"Haha, okay, thanks to Fusu for reminding me"

"Which one is not, really cunning"

"No wonder everyone sees each answer as an answer, making it difficult for them to choose."

Ying Zheng praised Fusu fiercely.

He almost made the wrong choice just now.

It was all because of Fusu's reminder at the critical moment and then gave him the real answer.

"It is the duty of sons and ministers to share the worries of their father. Fusu blushed at the praise and hurriedly replied.

Other ministers knelt down and shouted

"Congratulations to Your Majesty for receiving the divine food!"

"The Qin Dynasty will last forever, Your Majesty will last forever."

Ying Zheng was delighted.

How come the flattering words in the past were so sweet today.

When Ying Zheng saw the light curtain and began to learn about potato planting methods, he immediately ordered:"Come here, write down the planting methods quickly. Don't miss important events."

"yes! His Majesty."

The civil servant who had been waiting for a long time replied loudly.

【Popular science on how to grow potatoes】

【Potatoes are mostly propagated by tubers. They like cool, high and dry conditions and are highly adaptable to soil. Loose and fertile sandy soil is preferred.】

【Germination: Select qualified virus-free seed potatoes of suitable varieties. Take them out of the cellar 15 to 20 days before sowing, place them under scattered light at a temperature of 13 to 15°C, spread them in 2 to 3 layers, and turn them every 2 to 3 days to make the seed potatoes evenly exposed to light and promote strong sprouting. When the buds grow to about 0.5 to 1 cm, they can be cut into pieces. During germination, avoid direct sunlight, rain, frost, etc., and eliminate diseased and rotten potatoes in time.】

【Cutting: Cut into pieces 3 to 5 days before sowing. You can take advantage of the top buds and cut them vertically. If the seed potatoes are too large or oblong, you should cut them diagonally from the umbilicus to the top, and finally cut the top vertically. It is required that each cut piece ensures 1 to 2 strong bud eyes. The optimal weight of potato cubes is 35 to 50 grams.】

【Sowing date: When the soil layer is 10cm and the temperature stably passes 10℃ for 3 consecutive days, sowing can be done.】

【Sowing rate: 120 to 150 kilograms of seeds per mu】

【Density: ridges are made on flat ground or the original ridges are broken and then the ridges are closed. The ridge spacing is 80 to 90 cm. Single row cultivation is performed. The plant spacing is 15 to 20 cm. The soil covering thickness is 10 to 15 cm. The number of seedlings per mu is 4,000 to 5,000】

【Fertilization: According to soil fertility, apply decomposed farmyard manure at 2,000 to 4,000 kilograms per mu in combination with spring plowing. Pig manure is the best, followed by cow manure, and chemical fertilizers at 30 to 50 kilograms per mu.】

【......】

"Cutting and planting?"

This was the first time Ying Zheng saw this kind of crop.

No wonder he cut the potatoes open and didn't see the seeds inside.

It turned out that the whole potato was its seeds.

He stared at a thousand kilograms of potatoes and became curious. How many potato seedlings can be grown from these potatoes?

Seeing the fertilization method, he said happily:

"The fertilizer we just got is useful, let's try it out."
