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

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

【Seventh place: Cotton science popularization completed】

【In 3 minutes, the sixth popular science will start: soybeans. 】

People in all dynasties are accustomed to this scene.

Wait for new popular science content to appear.

While waiting, a huge question emerged in everyone's mind.

What is the"credit mall" mentioned in the popular science video?

Is it like a street stall where you can buy things?

If that's the case, what currency needs to be used to purchase it?

Everyone is puzzled

【Rest time is over】

【Start popular science No. 6: Soybeans】

【Soybean is an annual herbaceous plant of the Fabaceae family.】

【It is native to China and is cultivated all over the country. It is also widely cultivated in all parts of the world.】

【Soybean is one of the important food crops in China. It has a cultivation history of 5,000 years and was called Shu in ancient times.】

【According to the seed coat color and grain shape of soybeans, they are divided into three categories: yellow soybeans, green soybeans (green beans), and black soybeans (black beans).】

【The characteristics are as follows:】

【Soybeans are 30 to 90 centimeters tall. The soybean stems are thick, upright, and densely covered with long brown bristles.】

【Leaves usually have 3 leaflets; stipules are veined and covered with yellow pubescence; petioles are 2-20 cm long; leaflets are broadly ovate and papery; racemes are short with few flowers and long ones with many flowers; the total pedicel usually has 5 -8 sessile, tightly packed flowers; bracts lanceolate, strigose; bracteoles lanceolate, appressed setae; calyx lanceolate, flowers purple, lavender or white, with petals at the base The handle is leaf-shaped. The pods are plump, slightly curved, drooping, yellow-green, densely covered with long brown hairs; there are 2-5 seeds, oval, nearly spherical, with smooth seed coats, ranging from light green, yellow, brown and black.】

【The flowering period is from June to July, and the fruiting period is from July to September.】

【Growth habits:】

【Soybean likes warmth. The seeds start to germinate at 10-12℃, and the optimal temperature is 15-20℃. The suitable temperature for growth is 20-25℃. The suitable temperature for flowering and pod-setting is 20-28℃. The pod-setting is delayed at low temperatures and is lower than 14 ℃ cannot bloom, and plants that are too hot will stop growing early. Seed germination requires more water, and the soil moisture content is required to be 70%-80% during the flowering stage, otherwise the flower bud shedding rate will increase. The amount of fertilizer absorbed by soybeans before flowering accounts for less than 15% of the total amount, while the flowering and pod setting stage accounts for more than 80% of the total amount of fertilizer absorbed. 】

This time popular science.

The dynasties did not respond much.

Soybeans were cultivated even in the Qin Dynasty, and no one questioned whether they ranked sixth.

Qin Dynasty.

Inside Xianyang Palace.

Ying Zheng just drove away the traitor Hu Hai, and then ordered people to collect the cotton.

Popularizing science about soybeans on the light screen

"Shu, being ranked sixth is not surprising to me."

Ying Zheng made a casual comment.

【Limited time Q&A!】

【Tips: Please answer the following questions correctly within 1 minute】

【Which dynasty is the origin of soybeans closest to?】

【Option 1: Qin Dynasty】

【Option 2: Han Dynasty】

【Option 3: Three Kingdoms Period】

【Option 4: Yuan Dynasty】

【Option Five: Ming Dynasty]

When Ying Zheng saw the pop-up window, his expression froze.

Why is this Q&A not a rush answer, but an answer within a time limit?

Fortunately, the questions are not too difficult.

The obvious answer is the Qin Dynasty

"Your Majesty, this is option one, answer quickly."Li Si warned from the side.

The other ministers' faces were flushed with anxiety.

This was simply putting the benefits in front of their mouths. They only needed to open their mouths to eat.

Ying Zheng calmed down and replied loudly:"Option 1!"

What surprised him was that after several breaths passed, there was no response from the light screen.

Could it be that an emperor from another dynasty had already answered first?

Ying Zheng thought in his mind and shouted the answer to the light screen again.

Until the countdown on the pop-up window. Finish

【time's up】

【Congratulations to the emperors of all dynasties for completing the limited time Q&A. The reward: the entire process of making soy products. ]

Immediately afterwards.

A paper book appeared on the ground.

Ying Zheng stepped forward and picked it up himself.

As soon as he got it, he noticed something was wrong.

Writing can be written on it, but it is not cloth or bamboo slips.

He looked at Li Si and said puzzledly:"Prime Minister, come and see what this is, why it can be written on it and why it is so frivolous."

How knowledgeable Ying Zheng was.

In just a moment, he realized that the biggest reward this time was not the entire process of making soy products.

But the thing in his hand that can write words.

Li Si heard the summons and immediately stepped forward.

"Your Majesty, I am here."

He looked at the book.

The handwriting on it was clear and the text was neatly typed...

What shocked him most was that he could actually write on both sides!

Li Si said in surprise:"Your Majesty, this is probably the biggest reward this time, not text above"

"Haha, the prime minister and the widow have an idea."

Ying Zheng laughed heartily.

If he could figure out the material of the written items in his hand, it could completely replace the bamboo slips.

Ying Zheng had a headache when he thought about the memorials he dealt with every day.

All the memorials of the Qin Dynasty were made of bamboo slips.

That thing and the ones in his hands The items were simply incomparable. Not only were they very heavy, but there were also very few words that could be engraved on them.

In order to engrave more content on the bamboo slips, the words on them were usually made as small as possible. His eyes were drawn every time he looked at it. It’s uncomfortable.

I’m afraid the only advantage of bamboo slips is that they are durable in storage.......

He couldn't think that if he continued, he wouldn't even want to deal with tomorrow's memorial.

Ying Zheng gave up his random thoughts

"Show me, Prime Minister"

"Amazing, how is this thing made?"

"Prime Minister, even you don’t understand?"..............................................

Many ministers gathered in front of the book to express their opinions.

Li Si's face turned red due to the noisy discussions around him.

In terms of knowledge reserves.

Almost no one in Great Qin can compare with him.

But the light curtain in the sky can always create novel things that have never been seen before.

This made him, who had always claimed to be knowledgeable, feel ashamed.

I wish I could dig a hole in the ground and crawl in.

"Father, I request my father to let the craftsmen of Great Qin see this thing together, so as to benefit the students all over the world as soon as possible."

Fusu didn't know when he appeared.
