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

Han dynasty.

Liu Bang no longer knows what to say.

Throughout his life, he can be called a chosen son.

When he was young, he fooled around with his brothers every day, and he could climb into a rich family.

When he was about to enter the ground, Yingzheng died and the world was in chaos.

He took the opportunity to rebel.

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

Compared with the Americas, why is the fortune of other people's side stronger!

It's more like being favored by the heavens.

.............................

Shu.

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

But I always remember the sweet taste of popcorn in my mind.

'I'm going to eat popcorn.' ’

'Give me popcorn!'

In the next rush session, it would be nice to give a bucket of popcorn if you answered incorrectly.

Liu Chan's absent-minded state was fully seen by Zhuge Liang.

Zhuge Liang looked at the sky wistfully.

..................................

Tang dynasty.

Li Shimin was numb.

How to make America !? all good things

"Publish a notice throughout the country to find out where the Americas are?"

Li Shimin immediately issued a holy decree.

Song dynasty.

Zhao Kuangyin muttered to himself: "I should establish an empire in the Americas. "

[Popular science continues.] 】

[The artificial cultivation of potatoes can be traced back to about 8000 BC to 5000 BC. The world's potatoes originated from potatoes grown in the region of southern 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 Spaniards in the second half of the 16th century to spread. 】

[And then it was brought to the whole world by European explorers and colonizers.] 】

[The time of introduction to China is likely to be in the Wanli period of the Ming Dynasty in the 16th century. 】

【......】

Ming dynasty.

Zhu Yuanzhang was excited.

"Potatoes are also in our Ming Dynasty!".

"During the Wanli period..."

"Which descendant of Biao'er created the era name?".

When he saw the yield of potatoes per mu, he wanted to get them in his pocket.

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

At this time, even if you search the whole country, it is estimated that you will not be able to find it.

But how do you get potatoes?

Zhu Yuanzhang was in a hurry.

Suddenly, a pop-up window popped up from the light curtain.

[Rush to answer the question!].

Which of the following names is NOT another name for potatoes?].

Option 1: Potato

Option 2: Dutch potatoes

[Option 3: Ground Egg].

[Option 4: Yam Beans].

[Option 5: Artichoke].

Option 6: Yam Chunks

It just in time!

Zhu Yuanzhang took out the strength of the criticism.

Seeing six options, he was blindsided.

What's going on, how do you feel like you've seen every one of them in popular science videos?

Time waits for no one.

Take it slowly, and the reward will be snatched away by others!

Zhu Yuanzhang shouted directly at the light curtain: "Option one!".

He clearly remembers that the first nickname for potatoes was potatoes.

[Answer incorrect!].

[Congratulations to the Qin Dynasty for the success of the answer. 】

[Get 1,000 pounds of potatoes.] 】

！！！

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

He was absolutely right!

Potato is another name for potato.

At this time, Queen Ma came over and comforted: "Chongba, you can see clearly, which is not another name for potatoes, I didn't let you choose the correct answer." "

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

Until Zhu Yuanzhang answered incorrectly.

She read the question carefully before discovering the mystery.

When Zhu Yuanzhang heard this, he widened his eyes and glanced at it again.

I found out that it was really like that!

"Ahh "

Zhu Yuanzhang regretted it.

However, he didn't dare to get angry at the light curtain, so he could only sulk.

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

Is there still a way?

Zhu Yuanzhang's brain was running fast.

Soon, he suddenly came to his senses.

"Potatoes come from overseas, so let's just look for them overseas. "

After thinking about it.

An even bigger problem lies ahead.

Daming has a ban on the sea.

And it's only been a few years since it was enacted.

Do you want him to break the ban on the sea that he has made now?

.............................................

Qin Dynasty.

"Haha, okay, thanks to Fusu for reminding the widow. "

"Which one is not, really cunning. "

"It's no wonder that widows see that each is the answer, making it difficult for widows to choose. "

Ying Zheng praised Fusu.

He almost made the wrong choice.

It all depends on Fusu's reminder at the critical moment, and then gives the real answer.

"Sharing the worries of the father and the emperor is the duty of the sons. Fusu blushed from praise and hurriedly replied.

The other ministers knelt on the ground and shouted.

"Congratulations to Your Majesty on obtaining the Divine Food!".

"Great Qin forever, Your Majesty forever. "

Ying Zheng's heart is beautiful.

How can the words of flattery in the past be so pleasant today.

Ying Zheng saw that the light curtain began to popularize the planting method of potatoes, and immediately ordered: "Come on, quickly write down the planting method, don't miss the big thing." "

"Yes! Your Majesty. "

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

[Popular science potato planting method. 】

[Potatoes are mostly propagated by tubers, like cold and high dryness, and have strong adaptability to the soil, and it is better to have loose and fertile sandy soil. 】

[Germination: Select qualified detoxified seed potatoes of suitable varieties. 15~20 days before sowing, out of the cellar, placed at a temperature of 13~15 °C scattered light, tiled 2~3 layers, turned every 2~3 days, so that the seed potatoes evenly see the light, promote strong buds. When the bud grows to about 0.5~1 cm, it can be cut into pieces. Avoid direct sunlight, rain and frost during germination, and eliminate diseased potatoes in time. 】

[Dicing: 3~5 days before sowing. You can use the top bud advantage to cut vertically, such as the seed potato is too large or oblong, the cutting should start from the umbilicus to the top obliquely, and finally cut the top vertically, requiring each cut to ensure 1~2 robust buds, and a single potato piece weighs 35~50 grams. 】

[Sowing date: When the temperature of 10 cm soil layer is stable through 10 °C for 3 consecutive days, it can be sown. 】

[Sowing rate: 120~150 kg per mu. 】

[Density: ridge formation on flat ground or ridge after breaking the original ridge, ridge spacing 80~90 cm, single row cultivation, plant spacing 15~20 cm, covering thickness 10~15 cm. The number of seedlings per mu is 4000~5000. 】

[Fertilization: According to soil fertility, combined with spring ploughing, apply 2000~4000 kg/mu of well-rotted farmhouse fertilizer, pig manure is the best, followed by cow manure, apply 30~50 kg of chemical fertilizer per mu. 】

【......】

"Cut open planting?".

It was the first time Ying Zheng had seen this kind of crop.

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

It turns out that the whole potato is its seed.

He stared at a thousand catties of potatoes, and wondered in his heart, how many potato seedlings can be grown from these potatoes?

Seeing the way the fertilization was applied, he said happily:

"The fertilizer that the widow just got is useful, and let's see how it works. "
