Chapter 744: Ancient Artificial Ecosystems.

Many people looked back at Professor Tian and wondered if Tian Ying had any ideas?

But at this time, Professor Tian also looked at Su Huai with a panicked face, thinking that he didn't know anything about organic agriculture at all, what was Su Huai talking about?

I saw that Su Huai asked people to find a pen and paper, and then started to draw on it, his ink painting was famous all over the world, and various scenes appeared in a few strokes.

"Is this a fish pond?" Ren Na was taken aback, isn't it organic farming?

However, Dean Ebo did not make a fuss and said: "Organic agriculture, including all types of agriculture, animal husbandry, and fisheries, are among them. ā€

I thought, Su Huai actually wanted to start with fishery, what does this have to do with tea?

Just thinking like this, Su Huai actually drew another pigsty and sketched a few pigs with a few strokes, and everyone was speechless.

What's going on?

If you are not engaged in fishing, why is it engaged in animal husbandry again?

"Mr. Su, what are you focusing on?" Dean Ebo frowned.

Su Huai continued to paint silently, Anxi looked at it, and couldn't help but sarcastically:

"If you raise fish and pigs, you won't give fish meat to pigs as feed, this is not organic farming, but aristocratic food, but it is not surprising, we say that when we raise Wagyu, we should use shochu to smear the cow's body to stimulate the blood circulation of the cow's body. ā€

But Su Huai hadn't finished painting yet, he painted mulberry fields, silkworm raising, and tea forests by the fish pond.

Now everyone is confused.

What the hell is going on!?

The onlookers next to him, looking at the drawing, were full of doubts, and they didn't understand what kind of medicine Su Huai was selling in the gourd.

Seeing Su Huai put down the pen, Dean Ebo was a little speechless and asked, "Mr. Su, can you explain?"

"Professor Anxi, you are a top agricultural expert at Harvard, don't you understand?" Su Huai asked Anxi deliberately.

"Of course I see it. Anxi sneered: "This should be the pastoral life of Mr. Su's dream, he has built a farm, raised fish, and planted flowers, which is really comfortable." ā€

Su Huai took out a folding fan and said with a smile: "This is indeed a farm, but this is called an organic farm." ā€

Everyone was speechless...... Could it be that the name of the farm is "organic"?

Just thinking about it, I heard Su Huai say slowly:

"This is one of the records of Xu Qigong's "Complete Book of Agricultural Administration", artificial ecosystem, the earliest method of organic agriculture, simply put, is to dig ponds to raise fish, ponds to raise pigs, pig manure to raise mulberry, mulberry leaves to raise silkworms, silkworm sand to raise tea, ......"

Everyone looked at each other and did not understand the meaning of these four sentences.

Just now, Su Huai blew Xu Qigong's "Complete Book of Agricultural Administration" for a long time, and everyone could still be dragged by him, but I didn't expect that there was such a thing.

Dean Ebo was a little impatient and said, "Mr. Su, can you explain specifically." ā€

Today's discussion is in the field of agriculture, not poetry, but not you Su Sage, just take an ancient Chinese book and brag a few words, and you can mix it up.

In the face of doubts, Su Huai was still neither humble nor arrogant, and explained:

The first sentence, digging ponds for fish farming will dig out the low-lying fish ponds for fish farming, and the dug soil is piled up into a low bank, planted mulberry trees on it, tea trees are planted outside, aquatic vegetables such as cocoon white are planted on the edge of the pond, and a pig house is erected by the pond for raising pigs.

In this way, pigs can be raised without taking up arable land, and pig manure can be used as fertilizer for mulberry trees......"

Speaking of this, Professor Anthy exclaimed:

"Nonsense, pig manure contains coliform bacteria, nematodes and other germs and pests, and direct use will lead to the spread of pests and diseases, crop disease!"

Su Huai frowned and said: "Who said that pig manure should be used directly as fertilizer, of course, it must be fermented first." ā€

Professor Tian was surprised: "Wouldn't that be a fermentation plant?" If the factory is used to create industrial fertilizer, it will go against the original intention of organic agriculture......

The onlookers all shook their heads, Su Huai was clever but was mistaken by smart...... If it is equipped with a fermentation plant, plus electricity and equipment loss, it is better to buy ready-made fertilizer directly.

Dean Ebo waved his hand to interrupt Su Huai and said, "It's unrealistic, the cost of building a fermentation plant is too high, and the gains outweigh the losses. ā€

"Isn't this the fermentation factory that I have already built, haven't you seen it yet?" Su Huai pointed to the fish pond and pointed out the key point:

"I only need to carry out a simple compost fermentation treatment to eliminate pathogenic bacteria, and then use the pig manure as fish feed to feed the fish, and the pig manure is digested by the fish, which is equivalent to going through a fermentation process to form a natural plant fertilizer. ā€

Everyone was stunned, Su Huai really planned to make an artificial ecosystem?

The students around me listened and thought, how can it be so simple, this kind of similar experiment, the College of Agriculture does not know how many have been done, and they have never heard of success.

Suddenly began to flip through the books, thinking about it, and wondering if there was a precedent for feeding fish with pig manure.

Professor Tian listened, thought for a moment, and suddenly exclaimed:

"Good way, pigs can only digest 20%~30% of the nutrients in the suction food, and the rest are excreted with the feces, so pig manure is still nutritious feed!"

Su Huai nodded and smiled: "And some fish are corrosive fish, such as silver carp, they like to eat feces, and they like pig feces the most." ā€

Hearing Su Huai say that 'silver carp likes to eat feces', many students who have just turned to this knowledge point with a book are very surprised.

Hey...... It's strange, this Su Huai is not engaged in literature, but he still understands the knowledge of agriculture?

Su Huai didn't actually understand, but when he was taking an ancient Chinese science course, he specifically mentioned this thing, and he flipped through the relevant books, so the brain ability was fed back.

Professor Tian also exclaimed in surprise: "Yes, yes, and the digestion ability of fish is very weak, and the feces after digestion and absorption by pigs are more conducive to fish absorption after a similar fermentation and digestion process, and the growth rate of fish fry is improved!"

After listening to this set of explanations, the professors of the College of Agriculture at the scene all looked cautious, and even Dean Ebo showed a contemplative expression for the first time, and began to judge the possibility of Su Huai's way of speaking.

Professor Anthy lowered his head in contemplation, but sneered:

"What you think of is beauty, don't you know that Mr. Su doesn't know that there is no fish pond that only raises one kind of fish, although silver carp eats pig dung, but it only lives in the upper layer of the pond......"

A few of the students from the Agricultural College next to them were curious:

"Why can't there be only one type of fish in the fishpond?"

There are a few high-achieving students, disdainful:

"You don't even understand this, this is the basic fishery is only, if you want to have a high yield in the fish pond, you can't just raise a single fish fry, because different fish live in different depths of the water layer, so you must make a small ecosystem in the fish pond, try to improve the utilization rate of the fish pond ~~~"

"I'm not studying fishing, I'm majoring in animal husbandry...... How do you understand?"

Most of them, the students of the Agricultural College, don't understand it, and Su Huai naturally doesn't understand it.

Those fishery students deliberately said that this was "basic knowledge", just to deliberately ridicule Su Huai.

Unexpectedly, everyone wanted to laugh at Su Huai, but Su Huai looked at Anxi and praised for the first time:

"Professor Anzai is very reasonable, so grass carp should be raised in the middle layer of the pond, and carp should be raised at the bottom of the pond, and at the same time, dace and bighead carp can be ......"

"What do the other fish eat? These fish don't eat rotten food like pig dung......

This sentence was asked by Professor Tian, who was obsessed, and he wanted to applaud the students of the Agricultural College, thinking that it would be best for you, Professor Huaxia, to ask this.

Su Huai didn't care at all, but smiled:

"This is actually very simple, "The Complete Book of Agricultural Administration" records another kind of mulberry fish pond, saying: 'The silt in the pond, the cultivation of mulberry bamboo from every year, then the mulberry bamboo is lush, and the pond water is deep, with fish to raise mulberry, mulberry leaves to raise silkworms, silkworm dung to feed fish'......"
