Into Unscientific

Chapter 578: have you ever heard

Chapter 578 Have you ever heard of it?

“.”

Inside the office.

Hearing these words coming out of Li Jue's mouth.

Xu Yun's face instantly showed an emoji package of subway old man's mobile phone .jpg:

"??????"

Enough food for 10,000 people to survive the winter?

What the **** is this tmd?

You really think of your buddies as Doraemon, right?

After a while.

Xu Yun just came back to his senses, blinked, and asked Li Jue:

"Factory Manager, I'm sorry, I'm sorry that your words are a bit difficult to understand"

"What is food for 10,000 people in the winter? Could it be that our base is short of food?"

Currently, there are about 12,000 people in the entire base, and it is almost winter now.

In addition, Li Jue's identity generally doesn't mention things other than the base, so most of the things he said are related to the base—or at least Malan or the 504 factory.

as expected.

When Li Jue heard the words, a glint of gloom flashed in his eyes immediately.

Then he turned around and glanced at Lao Guo and the others, and nodded helplessly:

"Comrade Han Li, you are now considered a core member of the base and have the right to know some important secrets."

"Yes, the base is short of food."

Say it.

Li Jue's chest bulged, and he let out a foul breath.

A surprise flashed in Xu Yun's heart.

Is the base really short of food?

What's the situation?

To know.

According to some information declassified by later generations, during the development of nuclear weapons, the three major bases did experience material shortages.

When supplies are most scarce.

Don't talk about ordinary workers.

Even a member of the Chinese Academy of Sciences like Lao Guo, the vice president of the dignified Ninth Academy, and one of the heads of the base don't have many quotas.

And Lu Guangda.

Due to lack of adequate protein intake, Lu Guangda had a severe lump on his left foot, so that he was a little wobbly when he walked.

But on the other hand.

This lack of supplies mostly occurred in the early days of the establishment of the base, and the time period was often spring and summer.

After all, autumn is the season of autumn harvest, no matter how the crops are harvested, so there is relatively little shortage of food in autumn and winter.

Besides, with the vision and gully of the capital, it is impossible not to prepare winter supplies in advance.

Murphy

What's going on behind the scenes?

Fortunately, Li Jue is a straightforward person, and he didn't suffer from Xu Yun's problem of breaking chapters. He quickly explained:

"Comrade Han Li, you should have heard of Suicheng, right?"

Xu Yun nodded lightly:

"Of course I've heard that Suicheng has been the main granary supplying the Northwest Road since ancient times, and its geographical location is very important."

"So Suicheng is also called Marrow City, implying that it is the bone marrow and lifeblood of the Northwest Road."

Then Xu Yun blinked and seemed to realize something:

"Director, is there something wrong with Suicheng?"

Li Jue gave a muffled hum, and said very sadly:

"That's right, about a week ago, that is, the time when our base was researching the Zhu Xian project."

"At that time, some enemy agents sneaked into the city and set fire to the Suicheng granary. The burn rate of the grain prepared for our base in the granary exceeded 90%."

"At present, those enemy agents have been killed on the spot or arrested, but the burned food will never come back."

“.”

Xu Yun finally understood.

The principle is like this

He said how could the superiors only consider the matter of winter food at this time, it turned out that it was because of such an accident in Suicheng.

This kind of incident has nothing to do with the field of scientific research, and even later generations will not deliberately make it public, so it is normal for Xu Yun not to know the ins and outs in advance.

After a while.

Li Jue picked up the teacup, took a sip of water, moistened his throat, and said:

"Comrade Han Li, let me tell you the truth."

"Although the fire in Suicheng has made us a little passive, we still have some support in the organization. The base will not starve anyway."

"But the problem is that this kind of backhand is our real hole card. Once it is opened, we will not even have a pair of pants left."

"So Comrade Han Li, the organization would like to ask you if you have any good ideas or suggestions on this matter."

"Of course, don't have too much psychological burden. The organization will definitely not force you to do anything."

Heard what Li Jue said.

Xu Yun couldn't help but fell into deep thought.

Indeed.

As Li Jue said.

This matter is obviously not and should not be a category that he needs to solve personally, and the organization obviously doesn't really put the treasure on him.

but

To be honest.

When Li Jue finished explaining the cause and effect.

Xu Yun regarded this matter as an 'obligation' that he should solve.

After all, as a future Chinese traveler, how could Xu Yun remain indifferent to this kind of problem?

Before crossing, the country has to lift the pants, and after crossing, the country still has to lift the pants, so isn't he tmd crossing in vain?

That's too embarrassing!

Of course.

Emotion belongs to emotion.

When actually thinking about it, Xu Yun realized that.

This is really difficult.

After all, Li Jue said very clearly that this is the food prepared for this winter.

It is now the end of August, and it will be about three months before winter.

In other words.

Some methods of increasing production or even improving crops in later generations—not to mention that Xu Yun has no knowledge of this aspect at all, even if he has relevant reserves, he will not be able to use it at this time.

Other than that.

Don’t even think about the operation of carbon dioxide to synthesize starch:

Not to mention the required equipment and instruments, the catalyst used is more expensive than gold.

If you really have the financial resources to make synthetic starch, you might as well buy grain directly.

So he had to come up with a short-term operable and low-cost solution.

Think here.

Xu Yun's brows became more and more furrowed, showing a little embarrassment.

See this scenario.

A hint of disappointment flashed in Li Jue's eyes.

Sure enough.

Facing the food needed by thousands of people, even this magical half-cooked person has nothing to do.

So he paused, ready to change the subject again:

"Comrade Han Li, it's okay if you really can't think of a way, after all, this is not a person."

As a result, Li Jue didn't finish speaking.

Xu Yun suddenly let out a cry, raised his head slowly, and interrupted the second half of his speech:

"Director, I have a superficial idea about the problem of food shortage."

Li Jue was startled for a moment, and the second half of the sentence stopped in his throat.

After a few seconds.

On the contrary, Lao Guo reacted first.

唰—

I saw him standing up suddenly from behind the table, staring at Xu Yun:

"Xiao Han, what are you talking about? Do you really have a solution? — This is food for 10,000 people in the winter! Do you know what this concept is?"

“.”

Seeing this, Xu Yun didn't answer Lao Guo directly.

Instead, he went through his plan again in his heart, and then nodded lightly:

"Well, Director Guo, I personally think this is a practical solution—if my requirements can be met organizationally."

At this time, Li Jue finally came back to his senses, and hurriedly asked:

"Comrade Han Li, what exactly is your plan? Tell me about it?"

Right now.

Look at the whole scene.

Among the few people, only Fifth Master Qian's expression was relatively calm, but this boss was still a little surprised.

After all, as Lao Guo said.

That’s food for 10,000 people in the winter

Mentioned earlier.

Now the monthly ration quota for scientific research personnel in the base is 26 catties, and that for workers is 22 catties.

Even if more than 10,000 people are calculated according to the worker quota, 250,000 catties of grain will still be consumed in a month.

Three months in winter is 750,000 catties, which is a full 375 tons of grain, in fact, it is even more.

This number may not mean anything in 2023.

But for the rabbits at the moment, it is really a skeleton masturbation—squeeze the bone marrow to get it out.

“.”

Then Xu Yun paused, took a deep breath, and said to Li Jue:

"Director, you should know that if a person wants to keep healthy, it is not reasonable to rely solely on rice."

"That is, the nutritional ratio under normal circumstances should be the staple food plus some other nutrients—such as vitamins and more protein."

Li Jue nodded slightly.

Students who have attended high school biology should know it.

Protein and vitamins, they are all indispensable and important components of the human body.

Although rice also contains protein, it is mainly carbohydrates, but the content is not high:

One hundred grams of rice contains only about seven grams of protein.

But for the current base.

The vitamins in the two are relatively simple. After all, some vitamins can be ingested in the soup of elm leaves.

Although the elm leaf soup is very, very bitter, it’s better than no food, right?

And besides vitamins, protein is very difficult.

In the past, the protein in the base was mainly supplemented by a small amount of meat, ham sausage or eggs.

However, with the fire in Suicheng's granary, this source of nutrition has basically been cut in half.

In other words.

At present, there are actually two kinds of materials that the base needs most:

Staple food and protein.

After Li Jue figured this out, Xu Yun continued:

"So, factory manager, my idea is also divided into two parts."

"The first part is to supplement protein, and the other part is to supplement grains such as rice and wheat."

Old Guo kept up with his rhythm, and took the initiative to make a joke:

"Xiao Han, where are you going to get the protein?"

"Could it be that you have a way to engage in specialized breeding? For example, let sows and cows give birth to four or five cubs in one litter?"

Xu Yun's mouth twitched:

“.”

Why does this sound a bit strange?

Then he quickly waved his hand and explained:

"Guo Gong, the second half of your sentence is a bit flattering to me, I don't have that kind of ability."

"However, you are right in the first half of the sentence—yes, I am going to engage in farming, but the farming is not about chickens, ducks, cattle and sheep."

Old Guo thought for a few seconds, then suddenly said:

"Oh, that's raising donkeys?"

Xu Yun:

"????"

See this scenario.

Elder Wang couldn't stand it anymore, and couldn't help coughing lightly:

"Okay, okay, Lao Guo, don't make trouble."

"Xiao Han, go on, how do you plan to conjure so much protein?"

Perhaps due to the intersection of reality.

Xu Yun was still in awe of Mr. Wang, so he said immediately after hearing the words:

"Director, Guo Gong, I wonder if you have heard of an insect called the black soldier fly?"

"Black Soldier Fly?"

Hearing the word that came out of Xu Yun's mouth.

A question mark appeared on the faces of Lao Guo, Li Jue, Wang Lao and Fifth Master Qian:

what is this?

Then Xu Yun thought about it.

Take the pen and paper from the table, and draw a soul icon on the picture with the hand that can barely hold the pen:

A long black insect like a matchstick is lying on a leaf. It looks a bit like a fly, but its appearance is much higher than that of a fly.

Of course.

Although this picture is very different from sketching, it is not difficult to see that this thing is an insect.

See this scenario.

Old Guo couldn't help but touched his chin, thinking thoughtfully:

"Xiao Han, do you mean that you raise this kind of black water and other insects, and then bake or fry them like grasshoppers?"

Some insects have high protein content, which is a widely spread knowledge.

At the same time, for people of this age.

Eating insects is really not a rare thing, even some post-80s and even post-90s have eaten roasted grasshoppers in their childhood.

Like on the way to Guide County, Cai Shaohui saw a dung beetle and wanted to catch it and eat it.

no way.

The supplies these days are really scarce.

However, Lao Guo was somewhat surprised.

Xu Yun shook his head seriously, and explained:

"You guessed wrong, Guo Gong, I don't mean to eat adult worms, but to eat."

"The larvae of the Black Soldier Fly—or to be precise, the protein powder ground from the larvae."

Black Soldier Fly.

This is a very famous resource insect in later generations.

It is a flat-horned Soldier Fly animal of the Soldier family, and its English name is BlackSoldierFly.

Its adult shape is similar to that of a bee, non-toxic and harmless, with a body length of 13-22mm.

This is a saprophytic soldier fly insect that can feed on animal manure, domestic garbage and even weeds to produce high-value animal protein feed.

For example, in Xu Yun's later life.

Many places have introduced relevant breeding policies to fully support the black soldier fly breeding industry chain.

In addition to the versatility of adults, the larvae of the black soldier fly are also valuable.

first.

The larva of the black soldier fly is one of the resource insects designated by FAO, which is the Food and Agriculture Organization of the United Nations.

Its protein content is as high as 44%, second only to 51% of barley worms, and higher than mealworms and cherry cockroaches.

And unlike barley bugs.

The larvae of the black soldier fly do not contain pathogenic bacteria, but instead contain antimicrobial peptides—this thing can also resist pathogenic bacteria such as Staphylococcus aureus, Salmonella, and Shigella.

In "Edible Insects: Future Prospects for Food and Feed Security" released by the Food and Agriculture Organization of the United Nations in 2013, black soldier fly larvae ranked first in the edible prospects.

Indeed.

This kind of report is more forward-looking than practical. Today, protein powder made from black soldier fly larvae is mainly used as animal feed.

But the authority of FAO is still somewhat, at least more reliable than some Swedish girls.

For example, in Xu Yun's future generations.

There is already an official animal husbandry institution in Zhongzhou that is researching the preparation of black soldier fly larva protein peptides. The doi of the paper is 10.19369/j.cnki.2095-9737.2023.04.002.

Another example is the paper 10.13557/j.cnki.issn1002-2813.2022.12.015, which is a real National Natural Science Foundation of China project, project number: 51274153.

More critically.

Although the origin of the black soldier fly is America, it actually appeared in China as early as the 19th century.

The so-called [introduced into China in recent years] in the introduction of many black soldier flies actually refers to the breeding technology of black soldier flies, not the species itself.

Coincidentally.

The Black Soldier Fly happened to be a control group in the previous imidacloprid study, so Xu Yun and Qiu Sheng checked some information in depth.

One of the documents records that in November of this year, near the Sandieling Waterfall in Jingxi City, one of the 100,000 mountains in China, someone discovered a super large gathering point of black soldier flies:

The number of black soldier flies discovered at that time exceeded hundreds of thousands, but unfortunately, they were quickly wiped out by the local Jingxi local government with a plan to deal with locusts, because they thought it was a group of flies.

This incident was also recorded in the Jingxi county annals, located on page 778 of the 2000.2 edition of GX People's Publishing House.

Of course.

It is no wonder that the government officials at the time were in charge. After all, industrialized insect breeding is far from a mature industry at present—this industry will not enter a period of rapid development until the publication of the "Insect Breeding Manual" in 1985.

Right now.

Inside the office.

After listening to the information introduced by Xu Yun, the expressions of Lao Guo and others were slightly subtle.

After a while.

Old Wang and Lao Guo looked at each other and asked an important question:

"Xiao Han, I have a doubt that I would like to ask you to answer."

"As you said, although the nutritional value of black soldier fly larvae is high, can its output afford the daily consumption of more than 10,000 people in the base?"

Hear this statement.

Fifth Master Qian and others also nodded subconsciously.

be honest.

Eat insects when supplies are scarce.

This kind of plan was actually not thought of by the leaders in the past.

However, it is feasible for this thing to be used to solve a meal of food and clothing, but the long-term supply. At least the growth cycle of grasshoppers or locusts is not enough.

For example, Mao Xiong once tried to breed Siberian locusts, but found that the breeding cycle of this thing is too long, it is better to grow corn.

So from the first moment Xu Yun mentioned the Black Soldier Fly.

Whether it’s Lao Guo or Wang Lao, they all have a question in their hearts:

It’s okay to eat bugs, let alone grind them into powder, just.

Can this kind of insect really supply the nutritional intake of tens of thousands of people in the entire base for a long time?

"Sure."

Xu Yun nodded vigorously and explained:

"First of all, as long as the temperature is right, the black soldier fly will not overwinter."

“During the breeding period, a black soldier fly female can produce 1,000 eggs at a time. These eggs hatch in three days, and the larvae can be ground and eaten when they grow to the second stage—this cycle is about 7 days.”

"A second-stage black soldier fly larva is about two centimeters long and twice as wide as a mealworm. A single larva weighs about 3 grams and has a protein content of about 1.5 grams."

"And an adult consumes about 30 grams of protein per day—I mean the intake of our time."

"That is to say, in addition to deducting the 10 grams of protein that the staple food can provide, it is enough to eat protein powder of 15 worms a day."

"There are 12,000 people in the entire base, as long as there are close to 200,000 adult worms per day, it will be enough to support the protein intake of the base."

In Xu Yun's later life.

The normal protein intake of an adult is 1.2 grams per kilogram of body weight, which is about 70 grams per day.

But the current era is in the early days of the founding of the country, and it is obvious that this standard cannot be met.

Don't talk about domestic.

Mao Xiong and Duan Hai are not at this level.

Of course.

It won't be the same in another twenty years.

By then, the per capita protein intake will increase to 120 grams, even higher than in 2023

all in all.

The current per capita protein intake in the base is 22.8 grams. If it can reach 30 grams, it is considered quite sufficient nutritional intake.

at the same time.

Students who were black soldier fly larvae in their previous life should know.

The hatching period of black soldier fly larvae is generally three days, and then it will quickly enter the second stage of larvae within four days.

Even among all insects, this hatching cycle is considered fast.

And in this case, what is the output of black soldier fly larvae?

Take the Black Soldier Fly Breeding Base in the second phase of the Laogang Bioenergy Reuse Project in Shanghai as an example.

The whole base feeds 30 tons of wet garbage and solid **** every day, and the daily production of black soldier flies can reach 11 tons, which is 370,000 heads (see Xinmin Evening News report on November 17, 2012, the reporter is called Jin Minyi)

There is also the Black Soldier Fly Breeding Base in Xiquan Town.

The breeding greenhouse is only 7,424 square meters, and can produce 40,000 black soldier fly larvae every day.

Of course.

Seeing this, some students may ask:

No, later generations used kitchen waste to breed black soldier flies. It seems difficult to provide such a large amount of waste in this era, right?

This has to mention a dietary habit of the black soldier fly:

It will eat grass.

Base 221 is located in Jinyintan grassland, what does the word grassland at the end mean?

To know.

The Jinyintan Grassland covers an area of 1,100 square kilometers, larger than Tongling, the smallest prefecture-level city in later generations.

Don't talk about supporting black soldier flies for a whole winter.

Even if it is raised until 2023 when Xu Yun crosses, it is estimated that most of the grassland area is still left.

So as Xu Yun's introduction deepened.

The breathing of Li Jue and others became more and more rapid.

High nutrition,

Non-toxic,

reproduce fast,

Easy to feed.

Now, the condition that restricts the implementation of Xu Yun's plan is only whether the Hundred Thousand Mountains can find so many black soldier flies.

According to the abilities that Xu Yun showed before, it is possible that this information is true.

BIG BIG BIG!

"Comrade Han Li."

Then Li Jue thought of what Xu Yun said before, and said to Xu Yun:

"Then what's your second point?"

Xu Yun said earlier.

His plan is divided into two parts, one is protein intake, and the other is staple food.

Although protein intake is extremely critical, staple food is the real core focus.

"The second point."

Xu Yun pondered for a moment, then looked at Lao Guo beside him:

"Guo Gong, do you still remember what I said to you back then?"

Old Guo was stunned for a moment, subconsciously said:
