Qing Dynasty.
Kangxi returned to the palace directly.
Ignore the sky light curtain.
When the eunuch saw the time-limited question and answer session, he immediately went to report it.
But it's still a step too late.
This made Kangxi miss the reward
【Continue to popularize wheat science with follow-up content】
【Main values of wheat:】
【Nutritional value:】
【Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin and vitamin A. Due to different varieties and environmental conditions, the nutritional content varies greatly. Judging from the protein content, wheat grains grown in continental arid climate areas are hard and transparent, with high protein content of 14-20%. The gluten is strong and elastic, suitable for baking bread; wheat grains grown in humid conditions Containing 8-10% protein, the wheat kernels are soft, and the gluten is poor. It can be seen that the influence of geographical climate on the product formation process is very important.】
【In addition to being used for human consumption, flour is only used in small amounts to produce starch, alcohol, gluten, etc. After processing, the by-products are high-quality feed for livestock. Eating whole wheat can reduce the content of estrogen in the blood circulation, thereby preventing and treating breast cancer; for menopausal women, eating unrefined wheat can also relieve menopausal syndrome.】
【Nutritional components: The main components of wheat are carbohydrates, fats, proteins, crude fiber, calcium, phosphorus, potassium, vitamin B1, vitamin B2 and niacin, as well as allantoin. In addition, wheat germ is also rich in dietary fiber and vitamin E, as well as small amounts of arginine, amylase, sitosterol, lecithin and proteolytic enzymes.】
【Medicinal value:】
【Parts with medicinal value: Harvest the ears in autumn, dry them in the sun, break the fruits, remove impurities, take the mature fruits (wheat) and immature fruits (floating wheat), and dry them in the sun for later use.】
【Identification of medicinal materials: The wheat caryopsis is oblong, slightly pointed at both ends, up to 6 mm in length and 1.5-2.5 mm in diameter. The surface is light yellowish brown or yellow, slightly wrinkled, with a deep longitudinal groove in the center of the ventral surface, and yellowish white pubescence at the top. It is hard, white in cross-section, and powdery. The qi is weak and the taste is bland. Products sometimes contain uncleaned glumes and lemmas. The lemma is leathery, has sharp ridges, and has a pointed tip; the outer lemma is membranous, with a awn at the top, and the inner lemma is thick and papery, without awns.】
【Nature, flavor and function: Chinese medicine is sweet in taste and cool in nature. Wheat: nourishes the mind, calms the mind, and removes troubles. Floating wheat: replenishing qi, removing heat, antiperspirant】
【Indications: Treatment of restlessness, insomnia, irritability, irritability, mental depression, and sadness in women. Floating Wheat: Treats spontaneous sweating, night sweats, bone steaming and labor fever】
【Kind tips】
【Pesticides and fertilizers can increase crop yields】
【Subsequent food storage is equally important】
【Popular science on the storage methods of four types of wheat】
【1: Hot storage in warehouse: On a sunny day with high temperature in midsummer, dry the wheat to about 50℃ for more than two hours. When the moisture drops below 12.5%, gather it in piles around 3 pm and put it into warehouse while it is still hot. , random piles are covered, and the entire warehouse is sealed to keep the grain temperature above 40°C for about 10 days. All pests that have not died in the sun will die. Depending on the situation, the sealing can be continued or the ventilation can be switched.】
【2: Low-temperature freezing: Take advantage of the low temperature in winter to turn the warehouse, remove impurities, and freeze, lower the temperature of the wheat to about 0°C, and then seal it while it is cold. It has a good effect on eliminating overwintering pests in the wheat pile, but the low temperature Closed wheat piles must be strictly protected from contact with warm airflow to prevent condensation on the surface of the wheat pile.】
【Three: Natural hypoxia: It is high temperature when wheat is harvested. If it is dried and the water content drops below 12.5% in time, the characteristics of higher grain temperature and strong physiological activity in the post-ripening period can be used to seal the film to achieve the natural hypoxia state of the wheat pile. In order to suppress the harm of pests, for next-year old wheat, methods such as auxiliary oxygen reduction, or filling with carbon dioxide or nitrogen can be used to prevent and control pests in storage.】
【Four: Dry and sealed: As long as the wheat meets the storage requirements, it can be piled into the warehouse and sealed to prevent moisture absorption and insect pest breeding. This is especially effective in inhibiting the reproduction of wheat moths. In the high temperature season, pay attention to insect prevention, and be proactive after the autumn coolness. Ventilate, remove the lid to cool down and dissipate moisture; strengthen lidding or sealing after spring warms up 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 with the greatest scientific contribution to mankind!】
【Third place: Wheat science popularization completed】
【Three minutes later, the second place in popular science begins: potatoes! 】
Take advantage of the rest time.
The emperors of each dynasty ordered their servants to move the newly obtained expenses into the warehouse.
At the same time, people were asked to record the methods of grain storage in detail.
These are all valuable experiences for future generations, and they are all priceless treasures.
Three minutes flew by
【The ten crops with the greatest scientific contribution to mankind!】
【Let’s start with the second place in popular science: potatoes!】
【Alias of potato: potato, ground egg, yam bean, yam egg, Dutch potato, potato, ground bean, sun taro】
【It is an annual herbaceous plant of the Solanaceae family. Its above-ground stems are rhombus-shaped and hairy.】
【Potato leaves are single leaves when first born, and gradually grow into an odd number of unequal pinnate leaves, with alternate sizes, and are oval to oblong; corymbs grow at the top, and the flowers are white or blue-purple; the fruits are berries; the tubers are flat Round or spherical, hairless or sparsely pubescent; the skin of the potato is white, light red or purple; the flesh of the potato is white, light yellow, yellow and other colors. Flowering period summer】
【Potatoes are native to the mountains of tropical America】
【After thousands of years of cultivation, the yield of potatoes per mu is now between 4,000 and 8,000 kilograms.】
【......】
Qin Dynasty.
Ying Zheng saw familiar words again
"America"
"Still in America!"
Among the crops that have contributed the most to mankind, three of the top five are all from the Americas.
Moreover, there is still a number one that has not been popularized.
Who knows if the number one crop also comes from the Americas?
"This American widow must go!"
Ying Zheng secretly made up his mind.
