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

Chapter 27

Qing Dynasty.

Kangxi looked at the light screen.

I found out that it was another crop owned by the Qing Dynasty, and I instantly lost interest.

"Don’t even look at it!"

Kangxi was so angry that he shook his sleeves.

The reward he gave him last time was the stinky tofu, which disgusted him so much.

Looking back now, he still has no appetite when eating.

【Popular science continues】

【Compared with traditional rice, wheat and other food crops, corn has strong drought tolerance, cold tolerance, barrenness tolerance and good environmental adaptability.】

【Corn likes light but is intolerant of shade. It is a short-day plant.】

【The suitable temperature for growth is 22-30°C, the temperature for seed germination is 6-10°C, the temperature at the jointing stage is 15-27°C, the temperature for flowering is 25-26°C, and the temperature for grain filling is 20-24°C.℃】

【Characteristics of water and fertilizer requirements in different periods. Sowing - seedling stage: The amount of fertilizer and water required is very small, but it is very critical and important. There must be sufficient and appropriate base moisture to ensure full seedlings.】

【Seedling emergence - jointing stage: During this stage, corn requires less fertilizer and water, and moderate drought is conducive to squatting seedlings.】

【Jointing stage-large bell mouth stage: The amount of fertilizer and water required during this period increases, and nutrients and water should be appropriately increased to ensure the growth needs of corn.】

【Big bell mouth period - peak filling period: about 1 month. This period is the period when the largest amount of fertilizer and water is needed, especially around the silk spinning period. The lack of fertilizer and water at this time will cause malnutrition of the plant, weakened growth, and difficulty in tasseling. Poor pollination will cause severe yield reduction. Characteristics of water and fertilizer requirements at different stages. Sowing - seedling stage: The amount of fertilizer and water required is very small, but it is very critical and important. Sufficient and appropriate bottom moisture is required to ensure full seedlings.】

【Main values:】

【Nutritional value: The vitamin content in corn is very high, 5-10 times that of rice and wheat. Among all staple foods, corn has the highest nutritional value and health care effects. The riboflavin and other high nutrients contained in corn are very beneficial to the human body.】

【It is worth noting that the nutritional value of special corn is higher than that of ordinary corn. The moisture, active substances, vitamins and other nutrients of fresh corn are also much higher than that of old corn.】

【Medicinal value: According to the"Compendium of Materia Medica", corn is grown in the west soil. It is sweet and non-toxic, and can regulate appetite. Corn pollen and germ also contain a large amount of vitamin E and zeaxanthin. Regular consumption of corn products can delay human aging and enhance human physical strength and endurance.】

【Corn fructose syrup can prevent gum bleeding and has an auxiliary effect in the treatment of cardiovascular disease. Applying corn modified starch to burns on the human body can prevent scarring in the affected area. Corn starch is also a good medium for the production of penicillin. Sorbitol paste made from oxidized corn dextrose can be used to prepare ascorbic acid tablets. Corn also has the effect of beauty and slimming. Compared with soybeans and wheat, corn has lower fat and protein content and higher carbohydrate content】

【Corn silk, also known as"dragon whiskers", has a wide range of preventive and health care uses, so it is said that"one corn silk is worth two ounces of gold"】

【Studies have shown that the water extract of corn silk can not only reduce blood sugar in hyperlipidemia mice, but also improve blood lipids and hemorrheology; the total flavonoids in corn silk can significantly reduce serum total cholesterol in hyperlipidemia rats , triglycerides and low-density lipoprotein cholesterol levels, and increased high-density lipoprotein cholesterol levels.】

【Among the main components of corn husks, dietary fiber accounts for the highest content.】

【However, corn husks are not popular due to their rough taste and poor water solubility, and the dietary fiber content is not fully utilized, resulting in waste. Corn dietary fiber has the effects of lowering blood lipids, lowering blood pressure, and reducing the possibility of intestinal diseases.】

【When straw is crushed and returned to the field, it can slowly decompose and release mineral nutrients in the soil through the action of microorganisms in the soil, which can be absorbed and utilized by crops. The organic matter and humus formed during the decomposition process can provide raw materials for microorganisms and soil organisms in the soil. Can effectively improve soil structure and increase soil fertility】............................................

Qin Dynasty.

Ying Zheng looked sleepy.

This corn is quite good, but why don’t you give it to him?

Just tell him to just watch, right?

"Crush the straw and return it to the field?"

Ying Zheng murmured, this can be tried in the Qin Dynasty. It can actually increase soil fertility.

The Qin Dynasty also had a precedent, but they did not crush the straw and send it back to the fields.

The price is that pests are prone to occur.

【Weird trivia】

【A certain kimchi country likes to soak corn cobs in water and drink them. They also use this to mock our country for not knowing the goods and throwing away the most important thing in the corn.】

【As everyone knows, we all use corn cobs as dry firewood or crush them to feed livestock.】

【The reason for this is simple】

【As an island country, Kimchi Country is a small place.】

【Therefore, should one serving be used as two servings?】

【That’s why I got into the habit of soaking corn cobs in water.】

【Another piece of popular science knowledge】

【They also like to eat watermelon rinds and steal other countries’ culture】

"Hahaha, really interesting."

Ying Zheng was about to fall asleep.

He was suddenly amused.

This small country called Kimchi Country is quite interesting.

Our land is so small and small that we even eat corn cobs and watermelon rinds, but we are not ashamed and laugh at my huge country..

Zhao Gaole’s nose almost came out with bubbles,"Haha...Your Majesty, I have violated the etiquette, please punish me."

On the other hand, Li Si and the others were so depressed that their faces turned red.

If His Majesty hadn't been in front of them, they would have been lying on the ground laughing.

"I forgive you for your innocence." Ying Zheng tried to control his expression,"Everyone, you must remember that we are studying, and your attitude towards studying must be..."

"Hahaha!!!"

Before he finished speaking, he couldn't hold back any longer.

Because a video of Kimchi Country pickling watermelon rinds was playing on the light screen.

Then the screen changed.

Huaxia was pouring the remaining watermelon rinds from the family's meal into the pigs lock up

"Hahaha......"

Your Majesty has set a precedent.

The ministers present could no longer hold back.

No, you can't laugh. Learning is a very serious matter. unless...Can't help it.

Like now.

It’s really easy to hold things in without laughing.
