Anxi listened to the words of this "Complete Book of Agricultural Administration", but he was confused, and said slightly angrily:

"Mr. Su, what do you mean by saying it, why bother dropping your schoolbag in classical Chinese. "He studied science in elementary school and didn't know anything about classical Chinese.

But Dean Ebo on the side opened his mouth in surprise:

"What does Mr. Su mean is that the silt at the bottom of the pond is used as the foundation of the mulberry field to raise mulberry, and then the mulberry raises silkworms for the silk industry, and then uses silkworm manure to breed other fish?"

"That's the truth. Su Huai nodded with an expression of "Ebo Lao'er", and said to the mulberry field on the drawing with a folding fan:

"The mulberry pine of the mulberry fish pond is fertile, which is conducive to the development of the mulberry root system, and the pond surface is empty, creating good ventilation and light transmission conditions for the dense planting of mulberry trees~~~~ It was originally the best organic agricultural structure. ”

As he spoke, he pointed to the location of the fish pond:

The remaining silkworm sand is fed to the fish in the pond, mixed with grass carp, silver carp, bighead carp, dace and carp raised in the pond, which are divided into the upper, middle and lower layers, and each space can form different links in the food chain with aquatic plankton.

The excrement of fish, and the remains of other animals and plants, is decomposed into nitrogen, phosphorus, potassium, mixed into the mud pond, this pond mud, high fertility, long fertilizer efficiency, and drought resistance and prevent weed breeding, is the best fertilizer for mulberry trees......"

These are all things he sees from the Encyclopedia of Agricultural Administration, and the mulberry fishpond is not just a theory, but an agricultural project that China has vigorously promoted in the Jiangnan region.

It was demonstrated by modern agriculture, so Su Huai dared to say it.

At this moment, everyone listened to their scalps and couldn't help but feel a little numb, and the students of the Agricultural College were even more like hearing the book from heaven.

No one would have thought that the farm that Su Huai drew seemingly randomly on paper was actually an artificial ecosystem with a perfect interaction of water and land resources?

Structurally, the artificial ecosystem that Xu Guangqi has documented seems to be far superior to all the current organic farming estates.

The ancient book "The Complete Book of Agricultural Administration" mentioned by Su Huai is unheard of, but if the ancient Chinese people made it up, it would be impossible for Su Huai, a layman, to come up with such an artificial ecosystem by himself.

Could it be that the ancient Chinese were engaged in organic agriculture 500 years ago?

Is this possible?

Su Huai looked at the people in the Agricultural College, hanging his head, his face full of incomprehension, and he also secretly thought in his heart, although agriculture is a science, it needs more practice.

Although the ancient Chinese scientific theory was not developed, this kind of mulberry fish pond is the crystallization of thousands of years of agricultural wisdom of the Chinese people, and it has been done for thousands of years, and I don't know how many generations of improvement have been gone through to reach this perfect structure.

Although there is no theoretical basis, I don't know how many times more experimental samples than the experiments you did in the laboratory.

And in this time and space, no one has come up with this way, the most important reason is because silk is lost, and no one raises silkworms......

No one raises silkworms, naturally there is no large amount of silkworm dung, and this artificial ecosystem is missing a vital link, and of course no one will invent it.

However, although Anxi was a little flustered, Dean Ebo found the loophole of the Sankey fish pond after some contemplation, and Xu Guangqi's artificial ecosystem had two major problems.

I saw Dean Ebo say with a calm face: "Mr. Su's idea is good, but there are two things that still need to be discussed. ”

"Dean Ebo, please advise. Su Huai said.

Director Ebo pointed to the drawings and said:

"First...... The tea fields inside are redundant.

Secondly, and most importantly, whether silkworm manure can carry fish feed, I'm afraid no one has tried it yet, right?"

As he spoke, he turned his head to look at Professor Tian: "Has anyone in your Huaxia Academy done relevant experiments?"

Professor Tian was stunned and said, "This ...... Not really. ”

Dean Ebo looked at Su Huai again: "Mr. Su, have you done this experiment?"

Su Huai shook his head and admitted: "I only saw it in the ancient Chinese books, but I didn't actually do it. ”

Anxi finally came back to his senses and said in surprise: "In other words, what you are looking at are Chinese folk materials, and there is no actual evidence!"

The students of the College of Agriculture came back to their senses at this moment, and they all breathed a sigh of relief and muttered:

"...... I thought that the ancient Chinese were really so godly, but it turned out that they were just blowing. ”

"Without practice, how can you take it seriously?"

"In the future, there are many alchemical magic books in ancient Europe...... These charlatans' things can't be taken seriously. ”

Dean Ebo didn't make a judgment easily, just glanced at Su Huai, and said, "Mr. Su, whether this artificial system is feasible or not, let's go to the laboratory to test it." ”

"Okay~" Su Huai said to Ren Na: "Ren Na, you take two bags of our silkworm sand." ”

"Let's go to the chemical engineering laboratory of the Space Academy, Professor Nikina's laboratory equipment is relatively complete. Professor Tian said with some unease.

Dean Ebo saw that Professor Tian was afraid that the laboratory of their College of Agriculture would be ghostly, and he also nodded:

"Hmm...... The chemical engineering department of the Space Academy is indeed better equipped, so let Nikina inspect it. ”

Su Huai didn't know who Professor Nikina of the School of Chemical Engineering was, but seeing that Anxi didn't dare to speak, he was obviously an authority figure at Harvard.

But I still couldn't help but ask Professor Tian curiously:

"Can the Space Academy inspect our silkworm......

Professor Tian explained:

"The Department of Chemical Engineering includes subjects such as biochemistry, microbiology, fermentation technology, etc., and although several Harvard Polytechnic schools have chemical engineering laboratories, the equipment and personnel of the Space School are the strongest ......."

As he spoke, he whispered: "And Professor Nikina is Russian, and he hates himself the most." ”

"Why?" asked Su Huai.

Professor Tian rarely smiled: "Because many scholars have pursued Professor Nikina, and one has divorced her and finally threatened her with suicide, Professor Nikina is extremely disgusted with these perverted little devils. ”

No wonder, as soon as he said that he was going to the laboratory of the Department of Chemical Engineering, this Anxi didn't even dare to put a fart.

Everyone came to the Department of Chemical Engineering of the Space Academy, which is different from the quaint and old buildings of Huaxia College, the Space Academy is full of a sense of science and technology, bright light, the interior is full of metal and white chemical material furniture, and many people passing by are wearing protective clothing and other clothing.

The experimental area includes two whole buildings, and when he entered the door of the building, Professor Anzai took the lead and pressed his finger on the door, and the door opened with a "drip", and he glanced at Su Huai with a show off.

It's like saying, "See, this is the most cutting-edge fingerprint lock!"

Even Dean Ebo looked at Su Huai with interest, wanting to appreciate his reaction.
