Into Unscientific

Chapter 578 Have you ever heard of it

Chapter 578 Have you ever heard of it?

"."

In the office.

Hearing the words that came out of Li Jue's mouth.

On Xu Yun's face, an emoji package of subway old man's mobile phone .jpg appeared in an instant:

"??????"

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

What the hell 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, it's a little hard for me to understand what you said"

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

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

In addition, Li Jue's identity generally does not 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 this, 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 tinge of surprise flashed in Xu Yun's heart.

Is it really the base that lacks 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 shortages of supplies.

When supplies are most scarce.

Not to mention 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 developed a severe lump on his left foot, which caused him to walk a little wobbly afterwards.

But on the other hand.

This shortage of materials 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 harvest season, and no matter what the crops are, there will be some harvests, so there is relatively little shortage of food in autumn and winter.

What's more, with the vision and gully of the capital, it is impossible not to prepare winter supplies in advance.

Could it be

What's going on behind the scenes?

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

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

Xu Yun nodded lightly:

"Of course I've heard that Sui City 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:

"Factory Manager, is there something wrong with Suicheng?"

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

"That's right, about a week ago, that's 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 and brought to justice, but the burned food will never come back."

"."

Only then did Xu Yun understand.

The principle is so

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 our organization. The base will not starve anyway."

"But the problem is that this kind of backhand is our real hole card. Once it is lifted, 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 put too much psychological burden on you. The organization will definitely not force you to do anything."

Hearing Li Jue's words.

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

Indeed.

As Li Jue said.

Obviously, this matter is not and should not be a category that he needs to solve personally, and the organization obviously does not really put 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 had to lift his pants, and after crossing, the country still has to lift his 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.

It's 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 is only 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 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 equipment and equipment needed for this thing, the catalyst used is more expensive than gold.

If you really have the financial resources to make synthetic starch, it is better to buy grain directly.

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

Think here.

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

See this situation.

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

really.

Faced with 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 his sentence.

Xu Yun suddenly groaned, 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.

Swish——

He suddenly stood up 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?"

This moment.

Look at the whole scene.

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

After all, as Lao Guo said.

That's food for 10,000 people over the winter.

mentioned earlier.

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

Even if more than 10,000 people are calculated according to the worker quota, they still need to consume 250,000 catties of grain a month.

Three months in winter is 750,000 catties, that is, a full 375 tons of grain, actually even more.

That 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 squeeze 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 maintain a healthy body, it is not reasonable to rely solely on eating rice."

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

Li Jue nodded slightly.

Students who have taken high school biology should know it.

Proteins and vitamins are essential ingredients for the human body.

Although rice also contains protein, it is mainly carbohydrate-based, 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, isn't it?

In addition to 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. It is definitely not enough to pass the standard, but it is barely a pass.

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

In other words.

There are actually two kinds of materials that the base needs most at present:

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."

Lao 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?"

The corner of Xu Yun's mouth twitched:

"."

Why does this sound a bit strange?

Then he quickly waved his hands and explained:

"Guo Gong, the second half of your sentence is a little 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 planning to engage in farming, but the farming is not about chickens, ducks, cattle and sheep."

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

"Oh, that's raising donkeys?"

Xu Yun:

"????"

See this situation.

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

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

"Xiao Han, go ahead and talk, how are you going to conjure so much protein?"

Perhaps due to the intersection of reality.

Xu Yun was still in awe of Mr. Wang, and immediately said 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.

I took a pen and paper from the table, and drew a soul icon on the picture with a hand that could barely hold the pen:

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

Of course.

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

See this situation.

Lao Guo couldn't help touching his chin, and said 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.

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

no way.

These days the supplies are really scarce.

However, Lao Guo was a little surprised.

Xu Yun shook his head seriously, and explained:

"You guessed wrong, Mr. Guo, 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 of the Soldier family, and its English name is Black Soldier Fly.

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

This is a saprophytic soldier fly insect that can feed on animal feces, 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 diverse uses 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 the 51% of the barley worm, and higher than the mealworm and cherry cockroach.

And it's not the same as 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 among 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 much more reliable than that of a Swedish girl.

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 project of the National Natural Science Foundation of China, 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 many black soldier fly introductions actually refers to the black soldier fly breeding technology, not the species itself.

It's a coincidence.

The Black Soldier Fly happened to be a control group in the previous study on imidacloprid, 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 one hundred thousand, 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 county annals of Jingxi, located on page 778 of the 2000.2 edition of GX People's Publishing House.

Of course.

This is no wonder to the person in charge of the government at the time. After all, industrialized insect farming is far from a mature industry at the moment—this industry will not enter a period of rapid development until the publication of the "Insect Breeding Manual" in 1985.

This moment.

In the office.

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

After a while.

Wang Lao 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?"

I heard this.

Fifth Master Qian and the others also nodded subconsciously.

be honest.

Eat insects when supplies are scarce.

In fact, this kind of plan has not been 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, and it is better to grow corn.

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

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

There's nothing wrong with eating bugs, let alone ground them into powder, it's 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, an insect like the black soldier fly will not survive the winter."

"During the breeding season, 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's protein intake is about 30 grams a 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 future generations.

The normal protein intake for 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.

Let alone domestic.

The hairy bear and the opposite side of the sea are not at this level.

Of course.

Twenty years from now it won't be the same.

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

all in all.

The per capita protein intake in the base is now 22.8 grams. If it can reach 30 grams, it will be regarded as quite sufficient nutritional intake.

at the same time.

Students who were Black Soldier Fly larvae in their previous lives 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.

This hatching cycle is one of the fastest, if any, of all insects.

And in this case, what is the yield 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 entire base feeds 30 tons of wet garbage and solid slag 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 makes it necessary to mention a dietary habit of the black soldier fly:

It will eat grass.

And the 221 base 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.

Not to mention 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.

Therefore, as Xu Yun's introduction deepened.

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

high nutrition,

non-toxic,

breed fast,

easy to feed.

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

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

Very 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 had said earlier.

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

While protein intake is extremely critical, staple foods are 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?"

Lao Guo was stunned for a moment, subconsciously said:
