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

Qing Dynasty.

Kangxi went back to the palace directly.

Ignore the sky light curtain.

When the eunuch saw the time-limited Q&A session, he immediately went to make an announcement.

But it's still a step too late.

This made Kangxi miss the reward.

[Continue the follow-up content of popular science wheat.] 】

[The main value of wheat:].

[Nutritional value:].

Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin and vitamin A. Depending on the variety and environmental conditions, the nutrient content varies greatly. From the point of view of protein content, the wheat grains grown in the continental arid climate zone are hard and transparent, with high protein content, up to 14-20%, strong and elastic gluten, suitable for baking, and wheat grains born in humid conditions contain 8-10% protein, soft wheat grains, and poor gluten, which shows that the influence of geography and climate on the product formation process is very important. 】

[In addition to being used for human consumption, only a small amount of flour is used to produce starch, alcohol, gluten, etc., and the by-products after processing are high-quality feed for livestock. Eating whole wheat can reduce the amount of estrogen in the blood circulation, thus preventing breast cancer, and for menopausal women, eating unrefined wheat can also alleviate menopausal syndrome. 】

[Nutrients: The main components of wheat are carbohydrates, fat, protein, crude fiber, calcium, phosphorus, potassium, vitamin B1, vitamin B2 and niacin, as well as a component of allantoin. In addition, wheat germ is also rich in dietary fiber and vitamin E, and a small amount of arginine, amylase, sitosterol, lecithin and proteolytic enzymes in the heart. 】

[Medicinal Value:].

[Use value into the medicine part: harvest the fruit ears in autumn, dry them, lay the fruits, remove impurities, take the ripe fruits (wheat) and unripe fruits (floating wheat), and dry them for later use. 】

[Identification of medicinal materials: Wheat fruit oblong, slightly pointed at both ends, up to 6 mm long, 1.5-2.5 mm in diameter. The surface is light yellowish-brown or yellow, slightly shrunken, with a deep longitudinal groove in the center of the ventral surface, and the apex is yellowish-pubescent. Hard, white in section, powdery. The gas is weak and the taste is light. The goods sometimes have uncleaned slices and barleys, which are leathery, with sharp ridges and sharp processes at the apex, and membranous on the outside, with miscanthus at the apex, and thick paper on the inside, without mangus. 】

[Sexual taste function: Chinese medicine is sweet and cool. Wheat: nourishes the mind and calms the nerves, removes annoyance. Floating wheat: invigorating qi, removing heat, and relieving perspiration. 】

[Indications: Treatment of restlessness, insomnia, women's irritability, irritability, depression, sadness and crying. Floating wheat: treatment of self-perspiration, night sweats, bone steaming and labor fever. 】

[Tips.] 】

[Pesticides and fertilizers can increase crop yields. 】

[Follow-up grain storage is equally important.] 】

[Popular science about the storage methods of four kinds of wheat. 】

[1: Hot storage in the warehouse: in the middle of the summer sunny, high temperature weather, the wheat temperature to about 50 °C, continue for more than two hours, moisture drop to below 12.5%, around 3 o'clock in the afternoon, pile into the warehouse, while it is hot, scatter the cap, the whole warehouse is closed, so that the grain temperature above 40 °C for about 10 days, the pests that are not dead in the sun are all dead, according to the situation, you can continue to seal, can also be turned to ventilation. 】

[2: Low temperature freezing: when the low temperature in winter is used, the warehouse is turned, impurities are removed, and the wheat temperature is reduced to about 0 °C, and then it is cold and airtight, which has a good effect on eliminating the overwintering pests in the wheat pile, but the low temperature closed wheat pile should strictly prevent the contact of warm air current, so as to avoid condensation on the surface of the wheat pile. 】

[Three: natural hypoxia: wheat harvest is at high temperature, if dry and timely precipitation to below 12.5%, you can use the grain temperature is higher, the characteristics of physiological activity in the ripening period are strong for film sealing, to achieve the natural hypoxia state of the wheat pile, so as to inhibit the harm of pests, for the next year of old wheat, can be used to assist oxygen reduction, or fill carbon dioxide or nitrogen and other methods to control the storage of pests. 】

[Four: dry and sealed: as long as the wheat meets the requirements of storage, it can be piled into the warehouse, the gland is sealed, in order to prevent moisture absorption and insect breeding, which is particularly effective in inhibiting the reproduction of wheat moths, in the high temperature season to pay attention to insect prevention, after the autumn is cool, actively ventilated, uncover to cool down and disperse moisture; after the spring is warm, strengthen the gland or sealing, in order to keep the grain pile low temperature dry and insect-free. 】

In short, only by adopting scientific storage and preservation methods can the normal life characteristics of wheat be guaranteed. 】

[The ten crops that have made the greatest contribution to mankind in popular science!].

[Third place: Wheat science popularization completed.] 】

[Three minutes later, start the second place in popular science: potatoes!].

Take advantage of the break.

The emperors of each dynasty ordered their subordinates to move the money they had just received into the warehouse.

At the same time, let people record the method of grain storage in detail.

These are all valuable experiences for future generations, and they are all priceless.

Three minutes passed in a hurry.

[The ten crops that have made the greatest contribution to mankind in popular science!].

[Start the second place in popular science: potatoes!].

[Potato aliases: potato, ground egg, yam bean, yam egg, Dutch potato, artichoke, ground bean, artichoke, artichoke, artichoke. 】

It is an annual herbaceous plant of the Solanaceae family, with diamond-shaped stems and hairy stems. 】

[Potato leaves are single leaves at the beginning, and gradually grow into odd unequal pinnate compound leaves, alternating in size, ovate to oblong; umbel inflorescences grow at the top, flowers are white or blue-purple; fruits are berries; tubers are oblate or spherical, glabrous or pubescent; potato skin is white, light red or purple; potato flesh is white, light yellow, yellow and other colors. Flowering period in summer. 】

[Potatoes are native to the mountainous regions of tropical America. 】

[After thousands of years of cultivation, the yield of potatoes per mu is now between 4000~8000 catties. 】

Qin Dynasty.

Ying Zheng saw the familiar words again.

"Americas. "

"Still in the Americas!".

Three of the top five crops that contribute the most to humanity are all from the Americas.

Besides, there is still the first place without popular science.

Who knows if the first place is also from the Americas?

"This American widow must go!".

Ying Zheng secretly made up his mind in his heart.
