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

Qin Dynasty.

The piles of cotton piled up into a hill surprised everyone present.

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

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

He couldn't believe his eyes.

It is clear that there are three emperors who have succeeded in answering the question, and each of them can still get so much cotton.

"It's a bit more, it's wrong. Zhao Gao was very puzzled.

Hu Hai excitedly threw himself at the cotton.

Like a child who sees a novelty toy, roll in the cotton pile.

"Father, it's so soft, Erchen wants to take some back to the palace to play. "

After speaking, he looked at Yingzheng with blank eyes.

"Bastard!".

"Just know how to play!".

Ying Zheng immediately ordered someone to take Hu Hai away.

He picked up a ball of cotton from the ground and put it in the palm of his hand, muttering, "This thing is really as it says in popular science, it is extremely soft, and it is suitable for making clothes and bedding." "

Tearing open the cotton ball, he understood why only a large amount of cotton was given this time, not seeds.

It turned out that the seeds of cotton were hidden inside.

[Began to popularize the planting method of cotton. 】

【......】

Ying Zheng got up.

This is the second time he has been rewarded with it.

God bless Great Qin.

Ying Zheng's majestic voice echoed in Xianyang Palace, "Spread my will, and order all civil officials to be responsible for recording cotton planting methods." "

"No!".

The shouts in Xianyang Palace shook the sky.

Outside the city.

The peasants looked up at the light curtain in the sky.

They don't have much literacy, and they know from others that Daqin is going to have a new crop.

Next, we have to give them popular science planting methods.

At this time, you can win at the starting line by studying hard.

On the Great Wall.

Two soldiers defending the city patrol along the Great Wall.

"Shhhh Ha~~".

"It's getting colder. "

The other replied, "Who's to say it's not, well, you said that the clothes made of cotton are much warmer than the linen clothes we wear?"

"Nonsense, you don't have to think about it. "

As the two talked, their eyes kept glancing at the light curtain.

The centurion farther away saw this scene and ran over angrily.

"White... Hello centurion!".

"Patrol well, what kind of video to watch!" the centurion, a middle-aged man in his forties, pointed at the two and scolded directly.

One of them shouted mercilessly, "Dad, you're peeking yourself." "

The centurion's face was hot, and he shouted: "Stinky boy, I will beat you to death, and you will call me centurion in the army." "

He and his sons all joined the Qin army.

He is now guarding a section of the Great Wall that has just been built.

"Yes, centurion, can we receive the clothes from His Majesty in winter, the cotton must be very comfortable to wear. "

The centurion looked at his son.

There was silence for a moment.

He roared loudly: "What nonsense are you talking about stepping on a horse, keep a good eye on the grassland, even if Your Majesty wants to send winter clothes, you and I will wear them first." "

Chase the two away.

The centurion whispered the rest of the second half.

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

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

Han dynasty.

Before you see him, you hear his voice first.

Liu Bang's laughter echoed in the court.

"Hahaha, yes, I got my wish. "

"Congratulations to Your Majesty!" the many ministers congratulated in unison.

Liu Bang looked at the large pile of cotton that suddenly appeared, and instead of rushing to clean it up, he shouted: "Everyone, first watch with me how this thing is planted, this is a good thing for the future." "

The light curtain changes precisely at this time.

[The growth environment needs of popular science cotton:].

[Cotton growth requires a very large amount of light, and we must ensure sufficient light when planting cotton. 】

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

[Therefore, when we plant cotton, we should choose the planting plot in a sunny place. Then, according to the growth stage of cotton, the light should be reasonably controlled, and the photosynthesis of cotton will also be improved, and the photosynthetic matter in the plant will be increased. 】

[Cotton needs water and nutrients for growth and development, mainly obtained from the soil through the root system, and the required temperature and air are partly taken from the soil, and at the same time, it needs the mechanical support of the soil to grow. 】

[The physicochemical and biological properties of the soil in cotton fields greatly restrict the yield and quality of cotton. 】

[Soil moisture, nutrients, temperature, air, salinity, texture, etc. have a great impact on the growth of cotton. 】

..........

Liu Bang watched the popular science video.

While thinking to himself.

This time, the cotton was planted in Peixian's hometown first.

Give back to your former fathers and fellow villagers.

Shu.

Zhuge Liang was a little dumbfounded at this time.

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

Could it be that he and the first emperor Liu Bei have lost their eyes?

Liu Chan's mediocrity is all pretended?

"How did Your 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 rose slightly: "Father, I chose an option randomly, and I didn't expect to let me choose the right one." "

He knew that with his reflexes and memory, it would be extremely difficult to get a reward.

It's better to guess any one.

Anyway, there are only a few options, try a few more times, and you can always happen to choose the right one.

Zhuge Liang immediately sat back honestly.

I finally admired you once, and I actually lost so completely.

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

"Father, why is it sad?" Liu Chanke was still waiting to be praised.

"Minister... I hate that I made the wrong choice. "

Liu Chan: ???

Don't scare me, father, my country can be maintained by you alone.

[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 for 3~5 days to break the seed dormancy period, which can effectively improve the seed germination rate. 】

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

[In accordance with the fertilization principle of "nitrogen stabilization, phosphorus adaptation, potassium supplementation, micro-distribution, organic and inorganic combination", generally every 50kg of lint produced, about need to absorb pure N: 6~9kg, P2O3: 2~3kg, K2O: 6~8kg, vigorously advocate the application of organic fertilizer, in order to increase the permeability of the soil, change the situation of soil compaction caused by long-term application of chemical fertilizers. 】

[If conditions do not allow, plant ash or animal manure can be used instead of fertilizer ......].

[The specific operation method is as follows......

].

[Reasonable density: general cotton field (mu yield of 500 ~ 600 kg of seed cotton) is recommended mu density of about 3200 plants; high-yield cotton field (mu yield of 600 ~ 700 kg of seed cotton) is recommended mu density of about 3000 plants; small row row spacing of 50 ~ 55 cm, large row row spacing between 100 ~ 120 cm according to the density requirements of flexible control. Hybrid cotton or ultra-high-yield cotton fields (more than 700 kg of seed cotton per mu) or simplified pruning cotton fields, it is recommended that the density per mu is 2000~2500 plants, and the width of about 100 cm is used for planting in equal rows. 】

After watching the popular science video.

The people of Shu celebrated with the whole country.

Adou, who was looked down upon by everyone at the beginning, actually did a good deed for the benefit of the country and the people, which is worth celebrating!

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

They learned how to grow cotton.

When will the cotton seeds be sent?

I'm in a hurry, hurry up.
