Let you recycle scrap metal and bring back a 10,000-ton battleship

Chapter 202 shocked the world! Soilless cultivation?

"What I want is the design drawing of a 1000-acre plantation."

"You are much younger."

"Hurry up and change it for me."

Luo Feng was so angry, it turned out to be just a welcome robot.

For those complex calculations and designs, I am not good at it at all.

Can Luo Feng's design drawings be reduced so much?

It's also really weird.

"Dear guest, I remember that what you requested is only 1000 acres of planting area, right?"

"But there is no requirement. It covers an area of ​​1000 acres!"

"The two situations are fundamentally different."

Doudou Robot looked at the drawings he designed.

After being slightly stunned, he opened his mouth to explain.

For such a simple thing, although my own computing power is very low-level, I won't make mistakes, right?

The customer obviously only requested 1000 acres of planting area.

"Oh?"

Luo Feng also frowned slightly and continued to look at the drawing in his hand carefully.

He was surprised to find out.

Although the area covered by the drawing is indeed a standard area of ​​more than 300 mu.

But in the drawing, there is a four-story area.

If Luo Feng read it correctly, these soybeans are not planted directly on the ground, but are planted in buildings like buildings?

Each level is about 1200 acres, so the total area of ​​the four levels is just about acres.

Luo Feng originally thought that using nuclear fusion energy to provide plants was something unbelievable, but now, he can still see it? Such a weird planting method?

How many layers can this plant be planted in?

What if the soil is too thin? How to absorb nutrients from the soil?

"I'm sorry, Doudou, now I understand. It's true that you didn't design any less for me, but you have to explain, what's going on? What's the principle?"

There is no shame in asking if you don’t understand.

What's more, this is the high technology of Tianyuan Planet.

I don't know how many years ahead of the earth.

"Yes, distinguished guest, let me introduce it to you."

"I have checked and found that the building materials of that era 5100 years ago could only build about four floors of space."

“It can’t be any more, otherwise the gain will outweigh the loss.”

"Anyway, as you said, you don't have to consider the rigor of the movie. This can reduce the land area and save the cost of the movie."

"Since nutrient solutions can be used, there is no need to consider the thickness of the soil."

"Human science and technology develops to the end. If we still rely so much on the power of nature, then the development of science and technology is unnecessary. Human development is to overcome. Without nature, many things can be carried out in an orderly manner. Of course, the sun is still inseparable. After all, it is needed as the energy of nuclear fusion. However, the demand for soil is not so much, just a thin layer is enough."

When Luo Feng heard this, he nodded fiercely.

This is equivalent to the nutrient solution replacing the nutrients in the soil.

There is no need for a large amount of soil at all to allow crops to grow healthily.

"So in that case, why not just use nutrient solution to completely replace the soil? If it were completely replaced, there would be no need for soil. Wouldn't it be more trouble-free?"

Luo Feng thought for a while and then asked.

If this is possible, the seeds can be sown directly into the nutrient solution, and then they can take root and sprout.

"Haha, this is definitely not possible, because some nutrients in the soil cannot be replaced by humans. If they can be completely replaced, then of course there will be no need for soil. At this stage, only a small amount of soil is needed."

"That's it." Luo Feng nodded and continued to ask, "Then I still have to ask, can the soybeans grown with this nutrient solution and a small amount of soil extract oil? Don't let the oil extraction rate be too low by then, and How about nutrition? These are critical questions."

Be careful to make a thousand-year ship.

After all, Luo Feng has never seen the effect of such a planting method.

"Dear guest, you don't have to worry. This type of soybean seeds can of course be used to extract oil, and the oil extraction efficiency is quite high, about 25%."

"As for the soybean meal left after oil extraction, this kind of soybean meal actually has higher nutritional value and can be used as livestock feed without processing. However,"

Doudou robot paused when he said this.

Luo Feng said expectantly: "But what?"

"However, unless you use a retro breeding farm, synthetic meat is so cheap and tastes better than real meat. No one will bother to do the breeding business. There are indeed people who will breed pork and sheep today. , there are also a few people who need it, but most of them are used for pets.”

Damn it.

!!!

!!!

Luo Feng pursed his lips, a little unbelievable.

The technology of Tianyuan Planet today?

Is there any synthetic meat?

Of course, there are similar synthetic meats on the other side of the earth.

The cost is also low.

But why hasn't it developed? Isn't that because it is fake and has no nutrition?

But now on this planet, no one engages in breeding industry. What does this mean?

This means that synthetic meat has been accepted by everyone. Whether they are rich or wealthy, they all feel that there is no need to eat real meat.

In other words, the rich have accepted it, but you say this thing is not nutritious? is it possible? Rich people must eat nutritious food for their own health.

This kind of technology is many times superior to the synthetic meat on the earth.

If the synthetic meat on the other side of the earth can have the same nutrition as real meat and taste better, then why do people still eat real meat?

But for now, Luo Feng will not consider this thing.

If this kind of technology were to be brought to Earth, it would definitely cause huge troubles.

Think about it, pork, chicken, lamb, beef all over the world.

How big a market is this?

And all of a sudden, someone replaced them all?

How many big bosses will go bankrupt because of this?

How many workers will lose their jobs?

This time, it would be strange if there was no trouble.

Luo Feng even guessed that maybe many people would unite to suppress Luo Feng's high-tech synthetic meat.

Although they know that it is a good thing, they will still make all kinds of rumors, saying that synthetic meat is harmful to health.

"Does this soybean really have an oil yield rate of about 25%?"

Luo Feng was so excited just now that he forgot to ask.

This oil yield rate.

It can be said to be very high.

You know, the oil yield of imported soybeans is only about 18%.

The oil yield rate of domestic soybeans is lower, but still 16%.

The oil yield rate of peanuts is about 50%.

Sesame’s is 45%.

However, these things are too small.

Given their small size, even if their oil yield is high, they are not cost-effective.

On the contrary, soybeans are larger in size and cheaper than them.

So the main oil extraction, or choose soybeans.

Peanut oil and sesame oil are just seasoning ingredients and a small amount of consumables.

Soybeans are a treasure all over the body. After the soybean oil is squeezed, the remaining soybean meal is also very valuable.

In a word, soybean oil extraction is one of the best choices.

The soybean meal produced is also needed for animal husbandry.

Here in Daxia, the amount of soybean meal imported every year is almost equal to the amount of soybeans.

Since oil extraction and soybean meal can both be obtained, Luo Feng feels much more at ease now.

"Oh, by the way, in those days when it was such a big deal to tell our distinguished guests, certain nutrients shouldn't be needed, right?"

Hearing this, Luo Feng was puzzled, "What nutritional factors? What do you mean?"

"That is to say, in the age of 5100, some nutrients are not needed, and true soilless cultivation can be achieved. As long as the energy block of nuclear fusion and the nutrient solution can keep up, it doesn't need soil!"

"Combined with the unmanned automatic management system I designed, about five tons of soybeans can be produced in one season."

After all, Tianyuan Planet has continued to develop.

There are certain viruses in the human body, and they are perfectly integrated with the body.

Because viruses bring harm to people, they also have benefits.

If the harm caused by the virus can be eradicated.

Then it is not a virus.

But to eliminate these disadvantages, you need to take in some special nutrients.

And the plants cultivated without soil obviously don't have those nutrients, so they need a thin layer of soil.

"Is there such a thing?"

"That's a good relationship. If there is no soil, it will be more convenient."

Luo Feng chuckled, the good news came one after another and couldn't stop at all.

As for what the other party meant, Luo Feng also understood, that is, people from more than five thousand years ago, science and technology were not so developed, and they did not need certain nutrients that must be obtained from the soil.

Then there is no need to use soil.

Luo Feng could even imagine that once such soilless cultivation appeared on the earth, it would definitely shock the world.

"Dear guest, please look at the drawing. This is a very large-scale building complex, divided into square grid barracks one after another."

"As long as nuclear fusion energy is provided, the temperature and humidity inside can be guaranteed."

"The emergence of nutrient solution can even replace the soil, allowing plants to obtain most of the nutrients in the soil."

"So, in a place like this, no matter what season it is, crops are not afraid, and there is no need to consider production reduction or nutritional problems caused by changes in spring, summer, autumn and winter."

"Guarantee that at any time, it is the most suitable growth environment for soybeans."

Luo Feng was slightly moved when he heard this.

No wonder they can produce soybeans three times in one season.

In other words, this thing is a high-tech, upgraded version of greenhouse vegetables.

Such unified management is undoubtedly quite easy for Luo Feng.

However, after seeing this blueprint, Luo Feng had a bigger idea, and couldn't help but look forward to Shu.

Luo Feng thought for a while and decided to speak out, "Doudou Robot, I didn't make it clear last time. In fact, I have a piece of land covering an area of ​​1200 acres. Since you can build four floors, then I want to All 1200 acres of land are used, all of which are used to grow soybeans.”

"Is that so?" Doudou Robot smiled, "Dear guest, this is very easy. This is equivalent to expanding the area four times at once, right? As long as you slightly change the design, it can easily appear. There is a new design. However, since your scale has increased four times, the seeds I provide can only be supplied for a relatively shorter period of time."

"No problem, a year or so is enough."

Luo Feng chuckled. In a year's time, Luo Feng estimated that the entire Miaoxiang Kingdom would be cleared out of the surrounding ruins.

Will I still be able to find seeds by then?

"Son, where are you? Are Xiyan and you together?"

After Luo Feng returned to the earth.

Turning on the cell phone that was turned off, my father called.

"Well, Xiyan and I are finishing our meal."

Luo Feng picked up a piece of sweet meat and put it in his girlfriend's mouth.

While she was eating, she listened curiously to her boyfriend's phone call.

After all, this is a call from my husband, so she still takes it very seriously.

"Okay, if you two have time, come back and let us see your daughter-in-law, right?"

"Understood, dad, it's okay." Luo Feng chuckled, and looked at Li Xiyan, her face flushed as if she heard something.

After all, Dad’s voice is really loud when he calls.

You can hear some without turning on the speakerphone.

"That's okay, that's okay." Luo Hua smiled and talked about other things, "Son, your land has been approved. I know you must have asked someone to say hello, right?"

"Ah, almost!"

"I knew it wasn't a coincidence!" Luo Hua said, "But in the future, can you be more careful in your future work? The soybean yield per mu is 1000 kilograms. Aren't you just joking? I told you. , your father and now I can be considered a respectable person after all. If you fail to produce a thousand catties per mu by then, you will not only make a fool of yourself, but also make things difficult for those who are helping you."

Luo Feng picked his ears and said, "Dad, just wait. I don't dare to tell you too much, but I will definitely be able to achieve the expected yield of 1,000 kilograms per mu. I am not filling in random numbers."

"Can it really be done? Those are soybeans!"

"Yes, just wait. Technology is the first factor and fundamental driving force of production. If technology can advance, many things will be beyond the imagination of ordinary people."

Luo Feng chuckled. As long as technology develops, it will really help production a lot.

For example, in the past, who could have imagined that rice could be produced in such quantities per acre?

In the past, it was good to have a few hundred kilograms of rice per acre of land in ancient times.

And now? Under normal circumstances, the rice yield per mu can reach about 2000-3000 kilograms.

Of course, what was the yield per mu in ancient times? In fact, this is really hard to estimate.

Just do the math with ancient books.

"Historical Records Hequ Book" said: Qin opened the Zhengguo Canal, "Irrigated more than hectares of land with marinade, and harvested one mu for one Zhong".

The yield per mu is also 10 shi.

, the so-called "hundred acres" refers to an area of ​​1 acres. During the Warring States Period, one week mu was equivalent to 0.328 mu today. The "stone" mentioned by Ban Gu should be a Han Dynasty stone. One stone equals 1 city stones, which translates into 0.333 city stones per mu of millet today. One city stone of millet weighs 1 jins, which means that the yield of millet per mu at that time was 1.524 jins. .

Even after the Qin Dynasty, the rice yield per mu of later generations increased, but it would never exceed 500 kilograms.

This is technology.

This is the charm of genetically modified rice.

How could the ancient people have thought of such a high yield of rice per mu?

For example, Luo Hua and even others have never imagined that soybean yields can be so high.

The next day, after Li Xiyan came to the Magic City for repairs for a few days, she finally started working, but she only went in through a normal recruitment procedure.

This is Li Xiyan's own request.

Although she knew her little boyfriend was capable, she still wanted to try it out on her own to see if she could make a name for herself in the industry.

Luo Feng thought her thoughts were both cute and unnecessary.

After all, resources are obtained by oneself, so why not use them?

But if she wants to do this, Luo Feng should respect her choice.

Luo Feng, on the other hand, took his drawings back to Hangzhou that day. After all, he wanted to build a botanical garden base there, so he had to go back to Hangzhou anyway.

Li Xiyan also left someone to take care of her, so there won't be any problems.

Luo Feng didn't want to see his girlfriend being bullied or wronged.

When it comes to safety issues, it is natural to think carefully.
