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

Qin Dynasty.

The cotton piled up into a hill surprised everyone present.

Li Si rubbed his eyes and took a few steps forward to see more clearly.

"Your Majesty, the reward this time is too generous."

He couldn't believe his eyes.

It was clear that three emperors had successfully answered the question, and each of them could get so much cotton.

"There is indeed more, something is wrong."Zhao Gao was very puzzled.

Hu Hai jumped towards the cotton excitedly.

Like a child who saw a novel toy, he rolled in the cotton pile.

"Father, it's so soft. I want to take some back to the palace to play with."

After saying that, he looked at Ying Zheng longingly.

"Damn it!"

"Just know how to play! Ying

Zheng immediately ordered someone to pull Hu Hai away.

He picked up a ball of cotton from the ground and put it in his hand, murmuring:"This material is indeed as mentioned in the popular science. It is extremely soft and suitable for making clothes and bedding.""

After tearing open the cotton ball, he understood why only a large amount of cotton was given this time, but no seeds.

It turned out that the cotton seeds were hidden inside.

【Start popularizing cotton cultivation methods】

【......】

Ying Zheng stood up.

This is the second time he has been rewarded.

God bless the Qin Dynasty.

Ying Zheng’s majestic voice echoed in Xianyang Palace,"Preach my decree and order all civil servants to record the methods of cotton cultivation."

"promise!"

The shouts in the Xianyang Palace shook the sky.

Outside the city, the farmers looked up at the light curtain in the sky.

They were not well-literate and learned from others that Da Qin was going to have a new crop.

Then they had to teach them how to grow it.

At this time If you study hard, you will win at the starting line.

On the Great Wall.

Two soldiers guarding the city patrolled along the Great Wall

"hiss...ha~~"

"Innocence is getting colder and colder. Another person replied:"Who says not? Hey, do you think clothes made of cotton are much warmer than the linen clothes we wear?""

"Nonsense, you know it without even thinking about it."

While the two were talking, they kept glancing at the light curtain.

The centurion from further away saw this scene and ran over angrily.

"white...Hello Centurion!"

"Have a good patrol and watch some videos!"The centurion was a middle-aged man in his late forties. He pointed at the two men and cursed directly.

One of them shouted mercilessly:"Dad, you are just peeking.

The centurion's face was burning and he shouted:"You bastard!" I will beat you to death and you will be called Centurion in the army."

He and his sons all joined the Qin army.

Now they are guarding a section of the newly built Great Wall.

"Yes, Centurion, can we receive clothes from His Majesty in winter? Cotton must be very comfortable to wear."

The centurion stared at his son. He was silent for a while.

He shouted loudly:"What nonsense are you talking about while riding a horse? Keep an eye on the grassland. Even if Your Majesty wants to send you winter clothes, I and I will wear them first."

Drive away the two men.

The centurion finished the remaining part quietly.

"Of course, there is also your mother. I don’t know how she is doing at home alone. I’m afraid this winter will be difficult...."....................................

Han Dynasty.

Before I saw the person, I heard his voice first.

Liu Bang's laughter echoed throughout the court

"Hahaha, okay, I also got the reward as I wished"

"Congratulations to Your Majesty!"Many ministers congratulated in unison.

Liu Bang looked at the sudden appearance of a large pile of cotton. He was not in a hurry to clean it up, but shouted:"Everyone, first watch with me how to grow this thing. This is a good thing that will benefit the future."

The light curtain happened to change at this time.

【The growing environment requirements of popular science cotton:】

【The growth of cotton requires a lot of light. When planting cotton, you must ensure that there is sufficient light.】

【When the light duration is long and the intensity is appropriate, the cotton yield is high and the quality is good. If there is insufficient light, it will not only reduce yield and quality, but also have a great impact on subsequent seed conservation work.】

【Therefore, when we grow cotton, we must choose the planting plot in a place with sufficient sunlight. Then the light should be controlled reasonably according to the growth stage of cotton. The photosynthesis of cotton will also be improved and the photosynthetic substances in the plant will be increased.】

【The growth and development of cotton requires water and nutrients, which are mainly obtained from the soil through the root system. The required temperature and air are partly obtained from the soil. At the same time, it requires mechanical support from the soil to grow.】

【The physical, chemical and biological properties of cotton field soil largely restrict the yield and quality of cotton.】

【Soil moisture, nutrients, temperature, air, saline-alkali content, texture, etc. all have a great impact on cotton growth.】..........

Liu Bang watched the popular science video.

I thought to myself.

This time, the cotton was first planted in my hometown in Peixian County.

Give something back to your former parents and fellow villagers.

Shu Kingdom.

Zhuge Liang was a little dumbfounded at this time.

He clearly hadn't finished his answer yet, His Majesty answered first!

Could it be that both myself and the late Emperor Liu Bei were mistaken?

Is Liu Chan's mediocrity all an act?

"How did His Majesty choose the right answer?"Zhuge Liang suppressed the shock in his heart and asked curiously.

Liu Chan's face was full of pride, and the corners of his mouth were slightly raised:"Father, I chose an option at random, but I didn't expect that I chose the right one."

He knew that it would be extremely difficult to get a reward based on his own reflexes and memory. He might as well guess at random.

There are only a few options anyway. If you try a few more times, you will always get the right one by chance.

Zhuge Liang immediately sat back down.

Okay? It's easy to admire you once, but you actually let me lose so completely.

What the late emperor said is true, you are indeed Adou, I should have thrown you more times when I was a child!

"Father, why are you sad?"Liu Chan is still waiting to be praised.

"minister...I regret that I chose the wrong one."

Liu Chan:???

My dear, please don't scare me. I can rely on you alone to maintain my empire."........................................

【Preparation before sowing:】

【Dry seeds 15 days before sowing. The method is to spread the cotton seeds on a mat or dry hard ground to dry in the sun for 3 to 5 days to break the dormancy period of the seeds and effectively increase the germination rate of the seeds.】

【Scientific fertilization, determine the fertilizer ratio and dosage according to local soil fertility level and target yield.】

【According to the fertilization principle of"stabilizing nitrogen, suitable phosphorus, supplementing potassium, mixing microorganisms, and combining organic and inorganic", generally for every 50kg of lint produced, it is necessary to absorb about 6~9kg of pure N, 2~3kg of P2O3, and 6~8kg of K2O. , strongly advocates the application of more organic fertilizers to increase soil permeability and change the soil compaction caused by long-term application of chemical fertilizers.】

【If conditions do not permit, plant ash or animal manure can be used instead of fertilizer......】

【The specific operation method is as follows......】

【Reasonable density: In general cotton fields (with a yield of 500 to 600 kilograms of seed cotton per mu), the density per mu is recommended to be around 3,200 plants; in high-yield cotton fields (with a yield of 600 to 700 kilograms of seed cotton per mu), the density per mu is recommended to be around 3,000 plants; the spacing between small rows is 50 to 55 centimeters, and the spacing between large rows is 50 to 55 centimeters. The row spacing can be flexibly controlled between 100 and 120 centimeters according to density requirements. For hybrid cotton or super-high-yield cotton fields (with a yield of more than 700 pounds of seed cotton per mu) or cotton fields with simplified pruning cultivation, it is recommended that the density per mu be 2,000 to 2,500 plants, and planting in equal rows about 100 cm wide. 】

After watching the popular science video.

The people of Shu celebrated nationwide.

Adou, whom everyone looked down upon at the beginning, actually did a good deed that benefited the country and the people, which is worthy of celebration!

There is one more thing that they are particularly concerned about.

They learned how to grow cotton.

When will the cotton seeds be distributed?

I'm in a hurry, hurry up.
