"Okay, I'll not talk about it, you don't care." Huang Shi didn't expect that because of his few words, it would make Hong'er and Qu'er so uncomfortable, it was really waterfall sweat in his heart, it seems that the nerves of men and women are indeed different.

"It's nothing, it's nothing." Hong'er and Qu'er retched for a while, but they didn't really vomit, they just heard what the chief said so vividly, so that they suddenly seemed to see the hair pit in front of them, which was white maggots and black-brown feces, so they felt very nauseous, not only did they want to vomit, but they also had goosebumps all over their bodies.

"Alright, let's go back." Huang Shi saw that they were indeed fine, so he was relieved, so he proposed to go back and arrange for someone to come here to clean up later.

The three of them walked for a short distance, and when they were about to reach the gate of the base, Hong'er couldn't help it, because she was very curious about what the chief just said, so she said, "By the way, chief, you just said that those maggots can be fed to chickens, how can you raise them?" ”

"Well, let's put it this way, flies are pests that spread diseases, and there are a lot of bacteria and viruses on their bodies, so they can't be used to feed poultry directly, this is what I said earlier, you all remember, right?"

"Well, chief, you just said that."

"So above us, there are a lot of agriculturists who want to 'breed flies and turn harm into treasure', and among them, there is a professor at a very famous university. This university is not the 'university' in the 'Four Books and Five Classics' that you scholars here, but a 'primary school', a 'middle school' and a 'university' like this on our island.

Hong'er and Qu'er both nodded in understanding, because they all knew that the place where the children in charge of the snow clearing in Ludao was called a kindergarten, and the students taught by Song Meiling were considered elementary schools, just like the school that the Jiang family once ran, mainly to develop enlightenment, reading, literacy and practice words.

In fact, in ancient times, there were also "primary schools", but these two words did not refer specifically to schools at the earliest. In the Western Han Dynasty, it was called "primary school", and after the Tang and Song dynasties, it was called "primary school" as character science. To read, you must first be literate, master the shape, pronunciation, and meaning of words, and learn to use them.

During the Zhou Dynasty, when children entered school, they first had to learn Liujia Liushu, which refers to the strokes used by children to practice calligraphy, and the relatively simple six groups of cadres and branches that start with Jia. The six books refer to things, pictograms, shapes and sounds, understandings, transfers, pretenses, etc., so in the past, "philology" was called "elementary school", so the name "primary school" was derived from this.

In "The Balance of National History? "Introduction to Primary Schools" mentions, "Those who build primary schools, the foundation of the country's history, the end of the king's teaching, the upper to promote the school canon, the lower to the people's customs, how can it be a special introduction to the pen to draw the seal, pay around the text." Lost its origin, clever and hypocritical. ”

Therefore, "primary school" is China's "traditional linguistics", and the word "traditional" must be preceded by the word "traditional", because it does not refer to modern linguistics. It is usually said that "primary school" is text, phonology, and exegesis, and these "three" courses are "integrated", but they definitely do not exist in isolation.

The 'University' is one of the four classic works of Confucianism, including the Analects, Mencius, and the Mean, which was originally the forty-second chapter of the Book of Rites. It was the two brothers Cheng Hao and Cheng Yi of the Song Dynasty who extracted them from the chapters of the "Book of Rites" and rearranged the chapters and sentences. Zhu Xi then compiled and annotated the "University", "The Mean", "The Analects", and "Mencius", collectively calling them the "Four Books", and since then the "University" has become a Confucian classic.

However, after modern times, the meaning of "primary school" and "university" is somewhat different from that of the past, because with the strong attack of Western civilization, the cultural system and even the entire education system have undergone earth-shaking changes.

Seeing this, Huang Shi continued to say to Lu Xia, "As for this professor, after years of research, he has domesticated a kind of wild flies that are suitable for us to breed in captivity, and call them 'engineering flies'. ”

In fact, he was talking about the research results of Professor Du Rongqian of Nankai University in Tianjin, because he liked to watch the central 10 sets of "Approaching Science" and the central 7 sets of "Golden Land" and other columns very early on.

The program about Professor Du's scientific research achievements was rebroadcast on CCTV several times in January 2005, which not only aroused a strong response from many farmers, but also made Huangshi is memory deeply.

Because at that time, he liked to read the novel of crossing very much, and just saw that the protagonist mentioned the plot of running a farm with earthworm breeding in the novel, and at that time he was thinking that if he crossed by himself, he would do a fly maggot breeding, and the speed would not be faster, so this thing has always been very impressive.

I remember in the TV movie that flies live in dirty toilets, garbage heaps and other places where bacteria breed all their lives, but they do not get sick and can survive "family prosperity", and what does it rely on to resist the invasion of various germs?

Later, scientists discovered an antimicrobial active protein called antimicrobial peptide in flies. As long as the concentration of 1/10,000 of this antimicrobial peptide is enough to kill all kinds of germs. And in the vast population of plants and animals, flies grow extremely fast, accumulating only 9 dry matter. It can be doubled in 8 minutes.

Without interference from external factors, a pair of flies can breed 266 billion flies in a summer and produce more than 600 tons of protein, the production potential is very huge, and the cycle is very short, so far, there is no way to artificially produce so much animal protein.

And now if he breeds flies, then there are the following advantages, first of all, the production of raw materials is easy to obtain, because the raw materials for the production of fly maggots are mainly organic waste from industry and agriculture, which is very rich in sources, and the price is also very low in modern society, and it can also be found a lot on Dongluo Island.

The second is that it does not pollute the environment, and they do not need any epidemic prevention measures, nor do they need modern plants, do not produce toxic substances, and do not have odors. The third is that the feeding is simple and the input is very low......

But thinking of this, Huang Shi was stunned again, because he suddenly remembered that the two programs mentioned that farmers and friends were asked to use a large number of discarded crop straws, pig and cow dung, chicken dung and even human dung and urine in the vast countryside......

It is said that as long as people do it themselves, spend hundreds of dollars at a time, and build a little camp to start raising wild flies. Then the maggots will automatically gather together, and it will be very convenient for people to collect them, which is similar to what Hong'er just mentioned.

"Chief......" Hong'er saw why Huang Shi suddenly stopped talking, as if he was stuck there, so he hurriedly asked.

"Oh, by the way, he invented this kind of engineering fly, and then used their fly maggots to raise pigs, chickens, ducks, fish and other animals, because they can replace bone meal, fishmeal, and there is no need to add other trace elements to the feed, you can ensure that the animals raised grow fast and will not get sick."

"It's amazing!" Although Hong'er and Qu'er didn't know what the "trace elements" were, it didn't prevent them from letting out exclamations.

"yes, it's amazing!" Huang Shi also sighed, but not for this "engineering fly", but for the memory in his mind, no wonder everyone likes to travel over, his own memory that has been sunk is like an opening up, and the once blurry TV picture is now displayed in front of his eyes.

In the program, the raw materials for raising flies were also required, which required the addition of specially formulated EM strains, and the flies did not smell after adding this strain, and then they could be raised repeatedly, and the best organic fertilizer was returned to the field or used to fertilize the fish pond.

Huang Shi then said, "By the way, this project is very suitable for us, because there is an empty space for this kind of thing, or an empty house. We don't need to spend too much feed, just wheat bran, rice bran and some brown sugar, and we can breed it all year round, which can save a lot of money. ”

"Chief, it's okay, it's just that it won't look a little scary."

"Yes, it's a little scary to watch, but it works quickly." Of course, Huang Shi also admits this, he just saw so many flies when his scalp was numb, but if such a method is not adopted, then the modern and efficient breeding of poultry is impossible to talk about, and the white feather chickens of Kender chickens can be slaughtered in 45 days, isn't it a similar feeding method.

Hong'er and Qu'er glanced at each other, silently worried about cooking wine, it was already unbearable to let her raise pigs before, if she was asked to raise this fly again, would people go crazy.

After walking for a while, Huang Shi saw that the two of them didn't speak anymore, and the atmosphere seemed a little dull, so he said, "Actually, you can also raise another thing." ”

"What's that?" The two women asked in unison.

"Earthworms."

"Earthworms?!"

"It's the Earth Dragon, you know it." Huang Shi saw that they didn't know what to do, so he had to translate it into local "plain words".

Sure enough, as soon as they said "Earth Dragon", Hong'er and Qu'er understood, and they had also seen those older roosters and hens, often digging soil in the ground with their claws, and then finding the "Earth Dragon", pecking them off with a sharp mouth and then swallowing them, and I also heard the old people say that these "Earth Dragons" can also be used in medicine, so they have some interest.

"Chief, can this 'Earth Dragon' also be raised?" Although I have heard the chief say that he can raise flies just now, he can see what flies eat, and the "earth dragon" is different, hiding in the ground all day long, and I don't know what he eats to grow up.

"Hehehe." Huang Shi laughed, "Of course you can, you can raise any animal on us." "Don't talk about this kind of earthworm, even the national treasure panda is so picky, and it is also raised to be white and fat.

"Great, chief, then let's raise this." Hong'er clapped her hands and shouted.

"Well, I haven't finished talking yet, you just say okay, it's not going to work."

Hong'er spit out her fragrant tongue a little embarrassed, and quickly admitted her mistake, "Chief, I'm sorry, I was wrong." ”
