Video spoilers history, starting with the blitzkrieg on Poland

A new sky appeared.

A group of domesticated pigs appeared in the picture.

These domesticated pigs were milling around in an orchard-like area, rolling around on the ground, and it looked like an ordinary scene.

But there is something wrong with the colour of these pigs.

Generally speaking, domestic pigs are mainly white.

Then mix in some black, gray, brown, etc.

Even if you get dirty all over, it shouldn't be the color in front of you.

Because of these pigs in front of me.

Their color is actually blue!
If you zoom in a little, you can see these pigs eating tangerines and rolling around on the ground in the orchard, having a lot of fun.

This strange blue pig also caused exclamations from netizens.

What the hell?

"It's actually a blue pig. How terrifying!"

"This pig eats tangerines, and as a result, the food additives in the tangerines dyed it blue."

"This food safety is so scary."

"How weird, Piggy."

……

Not only modern netizens, but also most of the ancient people.

After seeing this group of blue pigs.

They all frowned deeply.

I think these pigs are very likely poisonous!
And the sky curtain continued to play slowly.

[Pig eats tangerines and turns into a blue pig? 】

[Is this a bronze vessel with a mouth or an Avatar with four legs? ]

[Soon, an article called "Sugar oranges cause trouble, pigs turn into Smurfs, who will protect food safety?" appeared online. ]

[The hot-selling article produced overnight by the marketing account spread like a virus. 】

[A certain self-media editor even wrote an "in-depth report" titled "Genetically modified ingredients detected in blue pigs", and the comment section instantly flooded with 3 vows to "never eat sugar oranges again."]

[Do pigs really eat blue? 】

[Of course not! ]

[Look, the color is uneven! ]

[Anyone who has lived in the countryside and seen the daily activities of pigs knows that pigs are lively and active by nature, and they love to roll around in all kinds of places.]

[So the blue color is probably rubbed off on them when they were moving around.]

[Some netizens analyzed, what is that blue thing? ]

[The most common low-toxic fungicide in citrus orchards is Bordeaux mixture! ]

【The so-called Bordeaux mixture. 】

【It really comes from Bordeaux, France. 】

[More than 100 years ago, vineyards in the Bordeaux region of France were wiped out by diseases. ]

【A local professor discovered that several grape vines miraculously survived on the roadside. 】

[The leaves are also painted with strange blue and white paint.]

[I found out after asking that some fruit farmers poured a mixture of copper sulfate and lime water on the grapes to prevent passers-by from stealing them.]

【From then on, Bordeaux liquid was born. 】

【Bordeaux grapes are saved! 】

[This discovery brought the European wine industry back to life.]

[This classic recipe is still used in orchards around the world today. 】

[Around the world, whether it is the attractive golden oranges in the citrus orchard, the red apples in the apple orchard, the vibrant peppers in the pepper field, or the fresh green cucumbers on the cucumber rack, etc. 】

【Bordeaux mixture still protects orchards around the world. 】

[The recipe has basically not changed. ]

【Copper sulfate + quicklime + water, that’s it. 】

[The golden ratio of 1 jin of copper sulfate + 1 jin of quicklime + 100 jin of water is considered the elixir of life in the agricultural industry. ]

[Yes, this blue color is often tested in chemistry questions.]

[Anhydrous copper sulfate, when added with water, turns into blue copper sulfate pentahydrate. ]

[The medicinal effect principle of Bordeaux mixture is not complicated. ]

[When it is evenly sprayed on the surface of fruit tree leaves, a solid protective film will quickly form. ]

[This protective film seems to have put on a layer of armor for the fruit tree leaves. ]

【The protective layer is firmly attached to it and is not easy to fall off. 】

[In the following period of time, it will slowly release copper ions, which are like tiny germ killers and can effectively hinder the normal functioning of enzymes in fungi.]

【Prevent fungi from causing trouble. 】

【At the same time, because it contains quicklime. 】

[It can not only inhibit bacteria to a certain extent, but also supplement calcium for fruit trees to a certain extent, promoting the healthy growth of fruit trees. ]

[Data from the Chinese Academy of Agricultural Sciences show that Bordeaux mixture reduces the incidence of citrus canker by 67%, while the cost is only one-third of that of chemical pesticides.]

[Every year, there is a trending news about "the vegetables you bought at the market turned out to be blue"

[Actually, that is also the residue of Bordeaux mixture! ]

[Will there be any problem if this thing is eaten by someone? ]

【The reason why Bordeaux mixture has been used for more than 100 years. 】

[In addition to being easy to use, it is also safe. 】

[Hey, then you are wrong. It contains copper, a heavy metal! ]

[The maximum tolerable daily copper intake of the human body is 8 mg. ]

[To reach this threshold, you need to not wash the vegetables with residue at all, and then eat about 4 kilograms in a row. ]

【As for the sugar orange? 】

[In the orchard, we mainly spray the outside of the fruit trees.] [We shouldn’t eat the leaves or the skin of the sugar orange, right?]

[So from the perspective of eating sugar oranges, you basically won’t ingest Bordeaux liquid. ]

……

[In fact, eating too many sugar oranges will indeed change color. 】

【People will turn yellow! 】

[The carotene content in sugar oranges is very high, and it is easy to eat sugar oranges and keep eating them. 】

【Continuously showing off more than three pounds. 】

[Unconverted beta-carotene may be deposited in the skin. ]

【The Minions appeared, and I was too embarrassed to see anyone! 】

【What can you eat to turn blue? 】

【Eat food with anthocyanins! 】

【If you eat mulberries and blueberries, your teeth will turn blue. 】

【Bluetooth!】

[Don't laugh! The Bluetooth on our cell phones is really blue because of our teeth.]

[It is said that more than 1000 years ago, there was a Nordic king named Harald. ]

[He is brave and good at fighting, and he likes to eat blueberries, so his teeth are often blue, and his nickname is "Bluetooth King". ]

[In 1994, the Ericsson team came up with this new technology and named it "Bluetooth" to pay tribute to him.]

【Bluetooth icon symbol. 】

[It is the combination of the initials of King Harald's name, the Nordic runes (H) and (B).]

【Back to the sugar orange. 】

[Sandangju is innocent, and so is Zhuzhu. ]

[It's just that the pig's hair has turned blue. ]

[Of course, it is possible that he may have touched something else. ]

[The photographer later contacted the local authorities.]

[The pigs turned blue because they spilled blue pigment powder in the factory.]

[It doesn’t matter if it’s Bordeaux liquid or something else. 】

[Anyway, it has nothing to do with the food safety of sugar oranges, so everyone should eat them! ]

The sky screen video ended here, and netizens' comments flew out one after another, saying that they had learned something new.

"It's so blue! Is that you, Yin Jiao?"

"It seems that Yin Jiao also likes to eat sugar oranges."

"The Smurfs at the Paris Olympics must have loved eating tangerines."

"The first solution we learn in junior high school chemistry, there are too many leaky fish."

"CuSO4+Ca(OH)2+H2O. 》

"In traditional Chinese medicine, copper sulfate pentahydrate is called copper sulfate."

"Self-media that spreads rumors randomly like this should be banned!"

"This needs to be popularized. There is really a blue residue on the green onion, and I have always been worried. "

《Little knowledge: Bordeaux liquid is a purely physical protection. Wash it thoroughly before eating. It is safer than pesticides.》

"As a fruit farmer, I say: 10 yuan for five kilograms of this stuff, if you want to try the technological blue color, just go buy some paint and dye it yourself!"

Today’s little knowledge: Bordeaux liquid really comes from Bordeaux, and Bluetooth really refers to blue teeth.

But the ancients gained even more.

Late Han Dynasty.

Zhuge Liang, who was in Jingzhou at this time, said with great interest:
"This Bordeaux mixture is really a wonderful method!"

"Diseases have always been a major problem affecting agricultural production."

"When I was in Longzhong, I often thought about farming methods. If there was Bordeaux liquid back then, the Longzhong orchard would have been more prosperous."

"According to the introduction on the skylight, this Bordeaux blue itself has an excellent protective effect against insect pests, and it also has no toxins or other side effects."

"Ji Chang, when you look at this liquid, can you see its great benefits for farming?"

Ma Liang quickly cupped his hands and said respectfully, "Military Advisor, this liquid can protect fruit trees and vegetables from diseases, and it has extraordinary effects."

"But this formula, I wonder if it is complicated to operate?"

Zhuge Liang shook his head slightly.

"Although the formula involves copper sulfate and lime water, the ratio is fixed and you can just follow it."

"Copper sulfate quicklime."

"Bile alum? I remember there were quite a lot of territories in Nanman and Liangzhou."

Zhuge Liang looked deeply and began to ponder.

He looked up again, his eyes full of desire, hoping that Tianmu could introduce more about the magical Bordeaux mixture.

And in the Northern Wei Dynasty.

Jia Sixie, a more professional agronomist, held the draft of Qi Min Yao Shu in his hands, and his hands trembled slightly with excitement.

There was excitement in his voice that was hard to conceal.

“This is truly a godsend!”

"This Bordeaux liquid is so effective in protecting fruit trees from diseases."

Jia Sixie paced back and forth, with a gleam in his eyes.

"I have traveled around for many years, collecting agricultural and sericulture methods, but I have never heard of such a sophisticated technique."

“It would have been great if I had known this earlier, recorded it in my agricultural book, and promoted it.”

"But it's not too late to know now!"

"I want to study this Bordeaux liquid in depth, record it in detail, and spread it."

"Let all fruit farmers in the world benefit!" (End of this chapter)
