A .jpg emoticon of an old man on the subway cell phone suddenly appeared on Xu Yun’s face:
"??????"
Enough food for ten thousand people to survive the winter?
What the hell is this?
You really think of me as Doraemon, don't you?
After a while.
Xu Yun just came back to his senses, blinked, and asked Li Jue:
"Director, I'm sorry, your words are a bit difficult for me to understand..."
"What do you mean, food for 10,000 people to survive the winter? Could it be that... our base is short of food?"
There are currently about 12,000 people in the entire base, and it's almost winter.
In addition, Li Jue's identity generally does not mention things outside the base, so most of the situations he talks about are related to the base - or at least Malan or the 504 Factory.
as expected.
Hearing this, Li Jue's eyes immediately flashed with a hint of gloom.
Then he turned around and looked at Lao Guo and others beside him, and nodded helplessly:
"Comrade Han Li, you are now considered a core member of the base and have the right to know some major secrets."
"That's right, the base... is short of food."
Say it.
Li Juebei's chest bulged and he exhaled a breath of thick air.
A hint of surprise flashed through Xu Yun's heart.
Is the base really short of food?
What's going on?
To know.
According to some information declassified later, during the development process of nuclear weapons, the three major bases did experience shortages of supplies.
When supplies are most scarce.
Let alone ordinary workers.
Even people like Lao Guo, a member of the Chinese Academy of Sciences, the vice-president of the Ninth Academy, and one of the directors of the base, don't have many quotas.
And Lu Guangda.
Due to a lack of adequate protein intake, Lu Guangda developed a severe swelling in his left foot, which caused him to stagger when he walked.
But on the other hand.
This kind of material shortage mostly occurs in the early days of the establishment of the base, and the time period is often spring and summer.
After all, autumn is the harvest season, and no matter how crops are harvested, there will be some harvest, so there is relatively little food shortage in autumn and winter.
Moreover, with the capital's vision and ravines, it was impossible not to prepare supplies for the winter in advance.
Could it be...
What's going on behind the scenes?
Fortunately, Li Jue was a straight-tempered person and did not suffer from Xu Yun's problem of breaking the text. He quickly explained:
"Comrade Han Li, you must have heard of Suicheng, right?"
Xu Yun nodded slightly:
"Of course I have 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 the Marrow City, which means the marrow and lifeblood of the Northwest Road."
Then Xu Yun blinked and seemed to have some realization:
"Director, could it be that... there's something going on in Suicheng?"
Li Jue let out a dull sigh and said with great sadness:
"Yes, about a week ago, that is the time when our base was studying the Zhu Xian project."
"At that time, some enemy agents sneaked into the city and carried out extremely atrocious arson on the Suicheng granary. The burning rate of the food prepared for our base in the granary exceeded 90%."
"At present, those enemy agents have been killed on the spot or captured, but the burned food will never be recovered..."
"...."
Only then did Xu Yun feel enlightened.
This is the principle...
He asked why the superiors were thinking about winter food at this time. It turned out to be because of such an accident in Suicheng.
This kind of incident has little to do with the field of scientific research, and it will not be deliberately disclosed even to future generations, so it is normal for Xu Yun to not know the ins and outs beforehand.
After a while.
Li Jue picked up the tea cup, took a sip of water, moistened his throat, and said:
"Comrade Han Li, I'm telling you the truth."
"Although the fire in Suicheng made us somewhat passive, we are still prepared to have some back-ups in our organization. The base will not starve under any circumstances."
"But the problem is that this backhand is our real trump card. Once it is revealed, we will not even have any 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."
After hearing what Li Jue said.
Xu Yun couldn't help but fell into deep thought.
True.
Just as Li Jue said.
This matter is obviously not... nor should it be something that he needs to solve personally. The organization obviously doesn't really place any value on him.
but......
To be honest.
When Li Jue finished explaining the causes and consequences.
Xu Yun regarded this matter as an 'obligation' that he should resolve.
After all, as a future Chinese traveler, how could Xu Yun remain indifferent to this kind of problem?
Before the time travel, the country had to lift its pants, and after time travel, the country had to lift its pants, so didn’t he travel through time in vain?
That's too embarrassing!
Of course.
Emotions are emotions.
In fact, when he thought about it, Xu Yun discovered...
This is really difficult.
After all, Li Jue made it very clear that this was food prepared for this winter.
It is now the end of August, and we are only about three months away from winter.
In other words.
Some methods of increasing production or even improving crops in later generations - not to mention that Xu Yun did not master this knowledge at all, even if he had relevant reserves, he would not be able to use them at this time.
Other than that.
Don’t even think about the operation of carbon dioxide synthesis of starch:
Not to mention the equipment and instruments required for this thing, the catalyst used alone is more expensive than gold...
If you really have the financial resources to develop synthetic starch, you might as well just buy grain.
So he had to come up with a plan that could be implemented in a short time and was not high cost...
Think of this.
Xu Yun's brows furrowed even more tightly, and his face showed a bit of embarrassment.
See this situation.
Li Jue couldn't help but have a flash of disappointment in his eyes.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Sure enough.
Faced with the food needed by ten thousand people, even this magical medium-rare man has nothing to do.
So he paused and prepared to change the topic:
"Comrade Han Li, it's okay if you really can't think of a way. After all, this doesn't belong to one person..."
As a result, Li Jue didn't finish his words.
Xu Yun suddenly snorted, slowly raised his head, and interrupted the second half of his words:
"Director, I have a superficial idea about the problem of food shortage..."
Li Jue was stunned for a moment, and the second half of his sentence stopped in his throat.
After a few seconds.
On the contrary, it was Lao Guo who reacted first.
Swish——
He suddenly stood up from behind the table and stared at Xu Yun:
"Xiao Han, what are you talking about? Do you really have a way? - This is food for ten thousand people to survive the winter! Do you know what this concept is?"
"...."
Seeing this, Xu Yun did not answer Lao Guo directly.
Instead, he went through his plan again in his mind, and then nodded gently:
"Well... Director Guo, I personally think this is a feasible plan - if my requirements can be met organizationally."
At this time, Li Jue finally came to his senses and quickly asked:
"Comrade Han Li, what is your plan specifically? Tell me about it?"
At this moment.
Take a look at the entire scene.
Among the few people, only Master Qian's expression was relatively calm, but the boss was still a little surprised.
After all, it is just as Lao Guo said.
That's enough food for ten thousand people to survive the winter...
Mentioned earlier.
Today, the monthly ration quota for scientific researchers at the base is 26 kilograms, and that for workers is 22 kilograms.
Even if more than 10,000 people are calculated according to the worker quota, 250,000 kilograms of grain will still be consumed in a month.
Three months in winter is 750,000 jins, which is a full 375 tons of grain. In fact, it is even more...
This number may be nothing in 2023.
But for the rabbits right now, it's really like masturbating with a skeleton - you have to 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 it is not reasonable for a person's body to stay healthy simply by 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.
Anyone who has taken high school biology should know this.
Protein and vitamins are both 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 among the two are relatively simple. After all, you can get some of the vitamins in the soup of elm leaves.
Although the soup made from elm leaves is very, very bitter, it is better than having no vegetables to eat, right?
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 or eggs. It was definitely not qualified, but it was barely qualified.
However, with the fire in the Suicheng granary, this source of nutrition has been basically cut in half.
In other words.
Currently, there are actually two types of supplies that the base needs most:
Staple food and protein.
After Li Jue figured this out, Xu Yun continued:
"So, director, my idea is 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 pace and took the initiative to praise:
"Xiao Han, where do you plan to get the protein from?"
"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:
"...."
This sounds a little 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."
"But the first half of what you said is correct - yes, I am going to engage in breeding, but I am not raising chickens, ducks, cattle and sheep."
Lao Guo thought for a few seconds and suddenly said:
"Oh, that means raising donkeys?"
Xu Yun:
"????"
See this situation.
Mr. Wang on the side couldn't stand it anymore and couldn't help coughing lightly:
"Xiao Han, please continue talking, how do you plan to produce so much protein?"
Maybe it's due to the intersection of reality.
Xu Yun was still a little in awe of Mr. Wang, and after hearing this, he immediately said:
"Director, Gong Guo, have you ever heard of an insect called the black soldier fly?"
"Black soldier fly?"
Hearing this word coming out of Xu Yun's mouth.
A question mark appeared on the faces of Lao Guo, Li Jue, Wang Lao and Qian Wushi:
what is this?
Then Xu Yun thought about it.
He took the pen and paper from the table and drew a soul diagram on the picture with his hand that could barely hold the pen:
There was a long black insect like a matchstick lying on a leaf. It looked a bit like a fly, but it looked much prettier than a fly.
Of course.
Although this picture is very different from a sketch, it is still not difficult to tell that this thing is an insect.
See this situation.
Lao Guo couldn't help but touch his chin and said thoughtfully:
"Xiao Han, do you mean to raise these black water bugs and then bake or fry them like grasshoppers and locusts?"
Some insects have high protein content, which is a widely spread knowledge.
At the same time, for people these days.
Eating insects is really nothing unusual. Even some people born in the 80s or even the 90s ate roasted grasshoppers when they were children.
For example, on the way to Guide County, Cai Shaohui saw a dung beetle and wanted to catch it and eat it.
no way.
Materials are really scarce these days.
However, what surprised Lao Guo.
Xu Yun shook his head seriously and explained:
"You guessed wrong, Guo Gong, I didn't mean to eat adult worms, but to eat..."
"The larvae of the black soldier fly - or to be more precise, the protein powder made from the larvae."
Black soldier fly.
This is a resource insect that is very famous in later generations.
It is an animal of the genus Platycornus of the family Hydroididae, and its English name is Black Soldier Fly.
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 hydrofly insect that can feed on animal feces, domestic garbage and even weeds to produce high-value animal protein feed.
For example, in the later generations when Xu Yun traveled through time.
Many places have introduced relevant breeding policies to fully support the black soldier fly breeding industry chain.
In addition to the various uses of the adults, the larvae of the black soldier fly are also valuable.
first.
The larvae of the black soldier fly are FAO... one of the designated resource insects by the Food and Agriculture Organization of the United Nations.
Its protein content is as high as 44%, second only to barley bugs at 51%, and higher than mealworms and cherry cockroaches.
And it's different from barley bugs.
The larvae of the black soldier fly do not contain pathogenic bacteria, but instead contain antimicrobial peptides - which can also resist pathogenic bacteria such as Staphylococcus aureus, Salmonella, and Shigella.
In the "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 terms of edible prospects.
True.
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 FAO still has some authority, at least it is much more reliable than some Swedish girl.
For example, in the later life when Xu Yun traveled through time.
There are already official animal husbandry institutions in Zhongzhou studying the preparation of black soldier fly larvae protein peptides. The paper doi is 10.19369/jki.2095-9737.2023.04.002.
Another example is the paper 10.13557/jki.issn1002-2813.2022.12.015, which is a real National Natural Science Foundation of China project, project number: 51274153.
More importantly...
Although the birthplace of the black soldier fly is America, it actually appeared in China as early as the 19th century.
The so-called [introduced into the country 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 imidacloprid study, so Xu Yun and Qiu Sheng also checked some information in depth at that time.
One of the records records that in November of this year, someone discovered a large gathering point of black soldier flies near the Sandieling Waterfall in Jingxi City, one of the largest mountains in China:
The number of black soldier flies found at that time exceeded hundreds of thousands. Unfortunately, they were quickly wiped out by the Jingxi local government using a locust treatment plan because they thought they were a swarm 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 cannot be blamed on the government officials at the time. After all, industrial insect farming is far from a mature industry at the moment—this industry will not enter a period of rapid development until the "Insect Breeding Manual" was published in 1985.
At this moment.
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.
Mr. Wang and Lao Guo looked at each other and raised an important question:
"Xiao Han, I have a question that I would like you to answer."
"As you said, although the nutritional value of black soldier fly larvae is high, can its production afford the daily consumption of more than 10,000 people in the base?"
Hear this.
Master Qian and others also nodded subconsciously.
be honest.
Eat insects when supplies are scarce.
In fact, this kind of plan has not been thought of by leaders in the past.
However, this thing is still feasible for providing a meal of food and clothing, but 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 was too long, and it was better to grow corn.
So from the first moment Xu Yun mentioned the black soldier fly.
Be it Lao Guo or Lao Wang, they all have one question in their minds:
There's nothing wrong with eating bugs, let alone grinding 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, insects like the black soldier fly will not survive the winter."
"During the breeding season, a female black soldier fly can lay 1,000 eggs at a time. These eggs hatch in three days, and when they grow to the second stage, the larvae can be ground into powder and eaten - this cycle is about 7 days."
"A second-stage black soldier fly larvae is about two centimeters long and twice as wide as a mealworm. A single worm weighs about 3 grams and has a protein content of about 1.5 grams."
"And an adult's daily protein intake is about 30 grams - I mean the intake in our time."
"That is to say, after deducting the 10 grams of protein that the staple food can provide, you only need to eat 15 worm protein powder every day."
"There are 12,000 people in the entire base. As long as there are close to 200,000 adult worms every day, it will be enough to support the base's protein intake."
In the future life when Xu Yun traveled through time.
The normal protein intake for an adult is 1.2 grams per kilogram of body weight, which is about 70 grams per day.
But this era is in the early days of the founding of the People's Republic of China, and it is obvious that this standard cannot be achieved.
Forget about China.
Mao Xiong and Haidian Duan are not at this level.
Of course.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Things will not be the same in twenty years.
By then, the per capita protein intake will increase to 120 grams, which is higher than in 2023...
all in all.
The current per capita protein intake at the base is 22.8 grams. If it can reach 30 grams, it is already considered a fairly sufficient nutritional intake.
at the same time.
Students who were black soldier fly larvae in their previous lives should know this.
The incubation period of black soldier fly larvae is generally three days, and then they will quickly enter the second stage of larvae within four days.
Even among all insects, this hatching cycle is considered the fastest.
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 Modu Laogang Bioenergy Reuse Project as an example.
The entire base feeds 30 tons of wet garbage and solid residue every day, and the daily production of fresh black soldier fly insects can reach 11 tons, which is 370,000. (See the Xinmin Evening News report on November 17, 2012, the reporter's name is 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 one of the eating habits of the black soldier fly:
It will eat grass.
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, which is 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 lasts until 2023, when Xu Yun travels through time, it is estimated that most of the grassland will still be left...
So as Xu Yun’s introduction deepened.
The breathing of Li Jue and others became more and more rapid.
Highly nutritious,
non-toxic,
Reproduce quickly,
Easy to feed...
The only condition that restricts the implementation of Xu Yun's plan is whether he can find so many black soldier flies in Shiwandashan.
And based on the abilities Xu Yun has shown before, there is a possibility that this information is true...
Very big!
"Comrade Han Li."
Then Li Jue thought of Xu Yun's previous words and said to Xu Yun:
"Then what's your second point?"
Xu Yun once said earlier.
His plan 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 and looked at Lao Guo beside him:
"Guo Gong, do you still remember what I said to you back then?"
Lao Guo was suddenly startled and subconsciously said:
"What are you talking about? Do you want to find a wife named Geng Sanwan?"
"......no no."
Xu Yun quickly shook his head and explained:
"I mean what I said back then...not whether it's possible, but..."
"Do you dare?"
"dare?"
Hear these three words.
Lao Guo's mind reappeared in the scene where Xu Yun and him were deaf...
After Xu Yun asked this question, he directly turned his attention to the electrostatic analysis module of the only electrostatic accelerator in China.
As for the subsequent story, everyone knows it.
And this time...
What is he going to do?
Then under the watchful eyes of Lao Guo and others.
The corners of Xu Yun's mouth curled up slightly:
"Guo Gong, have you ever heard of Feizhai Happy Water, which is as transparent as vodka?"
