Sun Xiangfu knew that these people in the audience who had not participated in breeding may have been frightened by the data he had calculated in his heart, so he spoke again, "We know the gap between chickens and ducks eating insects, fish and shrimp and eating grains, so let's calculate the cost gap between eating insects, fish and shrimp for these chickens and ducks and eating grains and grains."

There are more than 10,000 chickens and ducks, and it is impossible for the common people to feed so many insects, fish and shrimp to them, because from the perspective of the chicken raising technology that has been explored before, if you want chickens to raise more fat and lay eggs, you must raise them in a circle and reduce their activities.

If they can't be stocked, they won't be able to eat so many insects, and fish and shrimp, which itself has several times the value of food, if they are specially caught to feed chickens and ducks, it will be more than worth the loss.

Of course, we can still calculate its cost first, according to the actual situation, if you only use grain, to raise a thousand chickens, in fact, only one person can do it, a family, professional chickens, can reach thousands, or even more than 10,000.

However, to feed these chickens and ducks these high-nutrient insects, fish and shrimp, and green fodder made of mixed feed, then, at least two people need to be added to get these feed, just now you should have calculated, a thousand chickens through high-nutrient feed, a year can produce more eggs, and less death, more economic value of about 80,000 to 100,000 yuan, but two people, full-time to plant and collect insects, fish and shrimp, suitable for chickens to eat green plants as feed, labor costs, at the current price, it will almost consume more than 50,000 money, The real income that can be increased is actually only 3 to 50,000 yuan. ”

"A thousand chickens, you can earn an extra 3 to 50,000 dollars, that's also a great progress!" Seeing that Sun Xiangfu stopped to take a breath, the eldest grandson Wuji answered again.

For a richest man like him, thirty or fifty guan may not be nothing, but for the people, this is a lot of income, with the current grain price, this money can buy almost 1,000 stone of rice, which is almost 50 acres of high-yield rice field for two seasons!

The eldest grandson Wuji's role was played very well, and Sun Xiangfu took over the conversation again, "So, the problem is, our Datang not only raises a thousand chickens and ducks, but all the chickens in the country are counted, not to mention hundreds of millions of trillions, is it that these chickens all rely on people to catch insects, fish and shrimp to make feed to feed them?" ”

When everyone heard this, they knew why Sun Xiangfu wanted to raise flies, because everyone just thought about that picture in their minds for a while, and they all said, "Of course this is impossible!" ”

For 1,000 chickens, you need two more people to specialize in making feed, what about 100 million? What about a billion? What about two billion?

Datang won't let millions of people go to serve chickens and ducks!

Sun Xiangfu nodded and said, "So, just now, what this student wants to talk about is to help us solve this problem, maybe you didn't hear what he said, thinking that it just wants to raise flies, in fact, it's not, in addition to flies, there are many kinds of insects that reproduce faster can be raised, and feeding flies is just one of them with high efficiency, the technology is not complicated, and it can quickly achieve large-scale one, it is maggot-like before the adult, which is the food that chickens and ducks like to eat very much." ”

Hearing the word 'maggot', many of the officials present had a feeling of nausea and wanted to turn away, because they felt that there was nothing more dirty and smelly in the world than this thing.

Sun Xiangfu also smiled helplessly, "The maggots we want to raise are not the dirty maggots in the pit, and those dirty maggots have a certain amount of toxins in the body, if they are directly used to feed chickens, it may lead to an outbreak of chicken plague, which will make chicken farmers lose ······ weight."

Then, Sun Xiangfu will give you a more scientific method of raising flies and maggots, in fact, not engaged in this professional person, and do not understand what he said about space, temperature, and the like, only know that the place south of the Yangtze River has a warm climate most of the time, suitable for artificial cultivation of maggots, after the first few rounds of elimination, it can be made non-toxic, can be given to chickens and ducks in large quantities, that is, flies that die after laying eggs, and it is also a good feed for chickens and ducks.

Moreover, this thing, want to scale is very simple, only need to build some more than ten square meters, more sealed fly room becomes, a fly room, can raise at least 20,000 flies, only need to continue to feed a small amount of pig manure, chicken manure fermented feed, you can continue to get a large number of these flies maggots, so that the labor cost of chickens, and the cost of feed prices, down by more than half, moreover, it also solves the problem that the scale of chicken and duck breeding is too large, can not provide enough insects, The problem of mixing fish and shrimp meat feed for them to eat.

"This is the economic benefit created by bioscience and technology."

After Sun Xiangfu said this concluding remarks, all the officials on the scene, including the eldest grandson Wuji, were silent for at least a minute before they roughly understood what he said.

No one had ever thought of raising an insect as food for a poultry breed before, and that a whole set of very mature techniques had been developed in order to raise a large number of such insects.

Therefore, when everyone knew that they could do this, they suddenly felt that their two veins were opened up, and their spiritual wisdom was opened, and when they looked at the pictures of the biological chains posted on the blackboard of the activity, their eyes began to glow with golden light, because these are all ideas that can make them rich!

"It's still early, you can look at it board by board, a kind of understanding, I just roughly tell you, on the current Jiuyuan County learned to master the insect breeding technology, can be developed into a higher income industry, there are dozens of kinds. Like Li Yuanchang's side, after Wu Meiniang went, she should ask you to build a fly maggot house and an ant nest house! Next year, the number of red-headed centipedes that you have in Suizhou's specialty will definitely increase many times, Shanyang Pharmaceutical Factory, there should be no shortage of this medicinal herb in the future······"

Sun Xiangfu pointed this out to everyone, and immediately let everyone know that each biological chain on these pictures can indeed be applied to the actual industry, and they can better understand the importance of biological science and technology that Sun Xiangfu just said.

After a short time, Sun Xiangfu stepped down from the stage, and by this time, a student had already taken over the baton and began to talk about some scientific knowledge of other insects.

Actually, these flies! Ants! O earth turtle! Insects that are cultivated and only used as feed for other species are not high in economic value, and there are many species that have been cultivated during this period, but there is no scientific formation of large-scale species.

For example, during this period, it was already known that male ash worms could secrete white wax, lac worms could produce shellac, and cochineal insects could extract dyes, but because of backward breeding technology, they could not be used to make a large-scale industry and make their output benefit the whole people.

Sun Xiangfu popularized more of this biological knowledge to everyone, just hoping that everyone would make use of these resources available to human beings as soon as possible and make certain progress, like future generations, not to mention scorpions, white snails, mealworms, and Cordyceps, which is more expensive than gold and silver, have been artificially cultivated.

After quickly browsing through the biological chains and the biological introduction display boards, he grabbed Sun Xiangfu's arm and asked, "You Jiuyuan County School specializes in teaching these 'science and technology' that can help the people do industry?" ”

Sun Xiangfu nodded and said, "You can also say that!" I think that the purpose of human beings to grasp knowledge is to make their lives better, and this knowledge can play such a role. ”

Regarding Sun Xiangfu's concept, Changsun Wuji also agreed at this time, looked left and right, and whispered, "Then these students, my eldest grandson hired them back to develop the industry with a high salary, you have no opinion!" ”

Sun Xiangfu smiled and said, "Of course not, but after today, people from other families will probably have this kind of thought, and there may be a situation where the highest bidder will get it, because it is the freedom of these students to work in that company, and I have no right to interfere." ”

Sun Xiangfu cultivates talents, in order to promote social progress, naturally, but also hope that these people can realize their social value, make money, live a better life, children who grow up in this environment in Jiuyuan County, most of them are physically and mentally healthy, even if the family wants to use interests to win over and corrupt them, in fact, it is in vain, because, in the future, they will find that such talents will emerge more and more into the society, when the people are all talents, their set, it is useless.

Hearing this, the eldest grandson Wuji said a little depressedly, "There is no other way?" ”

Sun Xiangfu smiled again and said, "Why did you bring so many children from your own family?" Why do you ask me if there is any other way? ”

Hearing this, the eldest grandson Wuji said, "Fortunately, the old man guessed his intentions early on," but said, "But they come to learn by themselves, and after all, they are a little slower." ”

Sun Xiangfu shook his head and said, "It doesn't matter if it's slow, anyway, these things can't be made all at once, and in the long run, if you Changsun want to open up such an industry, you also need someone who knows how to manage it, right?" ”

The eldest grandson Wuji nodded in agreement, "That's the case, but if the old man sends the children of the clan to Jiuyuan County to study, I'm afraid the other families will do the same, and when the time comes, I'm afraid that your small Jiuyuan County won't be able to teach so many students!" ”

"That's why I let you stay nearly half of the place in Gangneung City! A capital-level city, there is no decent school, what is it called, the first batch of students who graduated from Jiuyuan County School are afraid that they will all go to educational positions in the future. Moreover, everyone comes to learn, then it is applauded, there is more demand, the scale will naturally be large, and when all the schools in our Datang teach practical learning, our country here will be powerful. ”

In Sun Xiangfu's view, the problem of education has never been so easy to solve, even if it is really practical-oriented, it is possible to eliminate many people because of the changes of the times, but fortunately he chose a relatively niche agricultural major, and before he graduated, he was sent to the school to practice in a local area, and then, directly persuaded him to continue to study in graduate school, in fact, throughout the college period, most of him was doing things, if it was like some other majors, he might have a lot of time on campus to talk about girlfriends, and live a few years very comfortable days, and then, With millions of fresh graduates every year, they are mixed in the vast sea of people, doing jobs that are completely incompatible with their majors.

Hearing Sun Xiangfu say this, Eldest Sun Wuji was a little surprised and said, "You have already thought about these?" ”

Sun Xiangfu shrugged his shoulders with a smile and said, "Do I need to think about these?" I've always gone there, and school education has been spread there! A century-old plan, education-oriented! If you look at Shanyang, it is the first place to implement all children to study, and now, has it begun to provide us with a steady stream of talents? ”

The eldest grandson Wuji thought about it, it was true, a few years ago, there were rumors among the people that doctors from all over the world came out of Shanyang, and now, it is not limited to medicine, those students who have completed their basic studies in Shanyang are now either studying in Chang'an Guozijian, or, they have directly passed the imperial examination and become officials, and the students of the Agricultural College have also graduated in batches from this year, and after that, there may be rumors that the world's agricultural officials have come out of Shanyang.

"Build, you have to build a big building, I will give Your Majesty a fold when I turn around, in addition, the old man also remembered one thing, you have affirmed that there are grain crops overseas that are different from my Datang, so, overseas, will there be insects and animals different from my Datang and the like?"

"Of course, the exploration team also has the responsibility of searching for these species, and if they can return safely next year, they should have some harvest."

In fact, Sun Xiangfu's previous search list for Zhao He contained many species of insects and animals, among them, mealworms native to North America are insects with great economic value, but I don't know if Zhao He can successfully bring it back.

"Then, can these new crops and insect pets be raised by my eldest grandson?"

"Those things are all from Overseas Exploration and Investment Co., Ltd., and your eldest grandson is already big enough, I'm worried about ······ if it continues to develop."

Sun Xiangfu still had half a sentence behind him, 'Your eldest grandson may not end well' that was not said.

And the eldest grandson Wuji, who understood what he meant, began to be cloudy and uncertain, the second richest man in the Tang Dynasty is not so easy to be, especially when his eldest grandson is a relative who is trusted by the emperor, the Guan Long family will automatically move closer to him and form a new super interest group that even surpasses the strength of the five surnames and seven families.
