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

Han Dynasty.

Liu Bang has ordered people to clean up the surrounding area.

The last time he drank, he made a mistake, which made him regretful.

You must know that the main food in the Han Dynasty was also millet!

How happy Ying Zheng is, how uncomfortable he feels

"Everyone, write down all the words that appear above for me, and don’t leave a single word behind."

The food and wine were all replaced by pens, inks, paper and inkstones.

All the civil servants held pens in one hand while recording the words that appeared on the light screen.

He didn't believe that there would be someone faster than him in the next question and answer session!

Shu Kingdom.

Liu Chan sat upright, like It’s amazing the scene when I was taught by my husband when I was a child.

"Rest assured, I will live up to your father's expectations this time, work for the benefit of the people of Shu, fulfill your father's last wish, and revive the Han Dynasty!"

Liu Chan stared straight at the light screen and exerted all his energy.

The servants on the side had never seen His Majesty have such fighting spirit.

He hurriedly brought a bowl of ginseng soup.

"Your Majesty, it's cold outside. Drink some ginseng soup to warm yourself up."

Liu Chan was unmoved.

This made Zhuge Liang look at him with admiration.

Late Emperor! Have you seen it?

Your son is not Adou who cannot be supported.

I will help him become a wise king.

There were a few tears in the corners of Zhuge Liang's eyes, but it was very difficult. Hurry up and calm down.

Tang Dynasty

"Auxiliary machine, you came just in time, come and help me quickly."

Li Shimin heard the report from the eunuch beside him and immediately stepped forward to greet Changsun Wuji who was coming.

"Your Majesty, I'm late."

Changsun Wuji bowed and saluted.

He felt very guilty for not being able to come to His Majesty in the first time.

When the light screen changed, he also looked up.

Taking advantage of the gap of science popularization, he hurried towards this direction. Came over.

The two exchanged a few words.

Changsun Wuji said solemnly:"Your Majesty, I dare to guess that this is a gift from heaven.""

"The purpose is to impart knowledge"

"But I'm afraid it's not just our Tang Dynasty that has this kind of curtain. Your Majesty must defeat enemies from other dynasties if you want to get rewards."

After hearing this, Li Shimin fell into deep thought.

He had a similar view.

The dynasties where the existence of the light curtain can be confirmed include the Qin Dynasty and his Tang Dynasty.

"Haha, okay, if I still find it boring if I am alone. Li Shimin clasped his hands behind his back,"So what if I compare myself with the emperors of other dynasties?""...

Ming dynasty.

Zhu Yuanzhang looked at the light curtain and smacked his lips.

He was really thirsty at this time. It would be nice if he could have some sugar cane.

"Hey, we have never seen sugarcane that can grow so tall. How does it grow? Li

Shanchang took the initiative to answer the conversation and replied:"Your Majesty, this must be an improved variety. I have never seen the sugar cane of the Ming Dynasty grow so well.""

Before he accompanied Zhu Yuanzhang to conquer the world, he personally planted sugar cane in his yard. He watered and fertilized it every day and took good care of it.

But in the end, the sugar cane was only as tall as a person.

"Good growth, you are right, this one is almost three people tall, it must be some improved breed."

Zhu Yuanzhang didn't know why, but he liked the crops that grew so tall.

Maybe it was because he was hungry when he was a child.

"Chongba, if you want to eat sugar cane, I will send someone to buy some outside the city later."

Empress Ma looked at Zhu Yuanzhang tenderly.

No one in the world knew Zhu Yuanzhang better than her.

"Our girl is better."Only when Zhu Yuanzhang faces his family will he show his completely gentle side.

【Popular science continues】

【How to make sugarcane more productive?】

【Deep plowing is the basis for increasing sugarcane production】

【The specific depth of deep plowing must be adapted to local conditions. It depends on the depth of the original plowing layer and soil properties. It generally requires about 30 cm.】

【The requirements for sugarcane ditches include width, depth and local conditions. Generally, the depth is about 20 cm, the bottom of the ditch is 20-25 cm wide, and the bottom of the ditch must be flat.】

【Fertilizing and watering requirements:】

【According to the fertilizer requirement of sugarcane, the application principle of top dressing can be summarized as"three attacks and one supplement, light at the two ends and heavy in the middle.""】

【"The three attacks are to attack seedlings, tillers and stems.】

【""One supplement" means to apply tail-strengthening fertilizer later.】

【""Light at both ends" means that less fertilizer is applied during the seedling stage and the later stage of elongation, while"heavy at the middle" means that more fertilizer is applied during the early stage of elongation.】

【Watering of sugarcane: Sugarcane requires large amounts of water but is not tolerant of waterlogging.】

【The general water demand trend is"less at the two ends and more in the middle""】

【The germination, tillering and maturity stages require less water, while the elongation stage requires more water.】

【Therefore, sugarcane fields must be kept in a"moist" state.】

【Therefore, in the early stages of sugarcane growth, although water demand is small, irrigation must be strengthened. The elongation period falls during the rainy season and generally does not require irrigation.】

【Seedling selection requirements:】

【Choose sugarcane seeds that grow well and are free from pests and diseases.】

【Plant selection is carried out during harvesting. Select upright, thick-stemmed, unflowered sugarcane plants as seeds; eliminate mixed varieties to ensure the purity of good seeds.】

【The length of the seeds depends on the needs. If the seedlings are sufficient, the top seedlings should be 30-50 cm.】

【Method of cutting seeds: cut off 2/3 of the lower internode of the bud, because the water and nutrients required for the germination of sugarcane buds are first supplied by the lower internode of the bud.

【Note: When planting in the cane, cut the buds to both sides and do not cut the cane seeds.】

【Seedling treatment:】

【Fresh seedlings have high water content and need to be sun-dried. When drying the seeds, peel off the older leaf sheaths first, leaving the young leaf sheaths, and put them in the sun for 2 to 3 days.】

【In production, two methods are mainly used: clean water seed soaking and lime water seed soaking.】

【It is better to soak seeds in running water and soak them at normal room temperature for 1 to 2 days. The method is to soak the entire bundle of sugarcane seeds in clean water for 1 to 2 days, then pick them up, peel the leaves, and chop the seeds.】

【The concentration of lime water for soaking seeds is 2%, and the optimal soaking time is 12 to 24 hours. The soaking time for seedlings at the base of the stem can be extended to 36 to 48 hours. The general principle is: when the seedlings are young, the soaking time is shorter when the temperature is high; when the seedlings are old, the soaking time is longer when the temperature is low. Soaking seeds in lime water can kill some mealybugs and pathogens, and also has a disinfecting effect】.............

Ying Zheng:"My eyes are dim after seeing it. Does it really want to teach me how to farm?"

Liu Bang:"You must write it all down. I will pass on this knowledge to the farmers next year. I will close my eyes and rest for a while."

Civil servants of the Han Dynasty:"Your Majesty, it's too difficult for us!"

Liu Chan:"Father, I'm tired. Let's drink some ginseng soup first. Don't be angry."

Li Shimin:"Assistant machine, come and look after me. My neck is a little stiff."

Zhao Kuangyin:"I can't bear it anymore, who will save me?"......

All the emperors complained one after another.

This popular science time is so hardcore!

He actually taught them something useful!

But they are emperors and they only need the skills to control people.

They are really not good at farming.

A pop-up window suddenly appeared on the light screen, catching everyone off guard

【Q&A session!】

【What kind of sugar can be extracted from sugar cane?】

【Option 1: Glucose】

【Option 2: Maltose】

【Option 3: Fructose】

【Option four: sucrose】

【Option 5: Lactose】..............................................

PS:

Ask for some data support.

I have been publishing the book for a long time, but I feel like there is nothing happening.

Flowers, comment votes, monthly passes, whatever, just give me a little, give me some confidence.
