Chapter 202 shocked the world! Soilless cultivation?
"What I want is the design drawing of a 1,000-acre plantation."
"Yours is much smaller."
"Hurry up and change it for me."< br>
Luo Feng is so angry, he is really just a welcome robot.
For those complex calculations and designs, I am not good at it at all.
How can Luo Feng’s design be reduced so much?
It’s really weird.
"Dear guest, I remember that what you requested is only 1,000 acres of planting area, right?"
"But there is no requirement, it is an area of 1,000 acres!"< br>
"There is an essential difference between the two situations."
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 1,000 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 in the drawing is indeed a standard area of more than 300 acres.
But on 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 300 acres, so the four levels added up will only cover an area of about 1,200 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 there are no less designs for me, but you have to explain, what's going on? What's the principle?"
Ask if you don't understand. There's no shame in that.
What’s more, this is Tianyuan Planet’s high technology.
I don’t know how many years it is ahead of the earth.
“Yes, dear guest, let me introduce it to you.”
"I have checked and found that the building materials of that era 5100 years ago can only build about four floors of space."
"It cannot be more, otherwise the gain will outweigh the loss."
" Anyway, as you said, you don’t have to consider the rigor of the film. This can reduce the land area and save the cost of the film.”
“Since nutrient solution can be used, there is no need to consider the thickness of the soil. "
"After the development of human science and technology, if we still rely so much on the power of nature, then there will be no need for scientific and technological development. The development of human beings is to overcome many things without nature. It can also be carried out in an orderly manner. Of course, the sun is still indispensable, after all, it is needed as the energy of nuclear fusion, but the soil does not need 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.
Crops can grow healthily without the need for a large amount of soil.
"Then in that case, why not completely replace the soil with nutrient solution? If it is completely replaced, there will be no need for soil. Wouldn't it be more troublesome?"
Luo Feng thought. After thinking about it, he still 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, of course there will be no need for soil anymore. At this stage, only a small amount is needed Soil."
"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 be able to extract oil? The oil extraction rate will be too low by then, and how about the nutrition? These are all is the key question. ”
Be careful about the ten thousand year ship.
After all, Luo Feng has not seen with his own eyes how effective this planting method is.
"Dear guest, you don't have to worry. This type of soybean seeds can of course be used for oil extraction, 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,"
The Doudou robot paused at this point.
Luo Feng said expectantly: "But what?"
"But, unless you use a retro breeding farm, synthetic meat is so cheap and tastes better than real meat. No one would bother to go into the breeding business. Today, there are indeed people who breed pork and sheep, and a few people need them, but most of them are used as pets. ”
Damn it.
! ! !
! ! !
Luo Feng pursed his lips, a little unbelievable.
What is the technology of Origin 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 this 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, mutton, beef all over the world.
How big a market is this?
And suddenly, someone replaced them all?
How many big bosses will go bankrupt because of this?
How many employees will lose their jobs?
This time, it would be strange if there was no trouble.
Luo Feng even guessed that perhaps many people would unite to suppress Luo Feng's high-tech synthetic meat.
Although they know it is a good thing, they still spread all kinds of rumors, saying that synthetic meat is harmful to health.
“Does this soybean really have an oil yield of about 25%?”
Luo Feng was so excited just now that he forgot to ask.
This is the oil yield.
It can be said to be very high.
You know, the oil yield of imported soybeans is only about 18%.
The oil yield 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.
With 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.
Therefore, the main choice for oil extraction is 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 of high value. 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 are both the same, Luo Feng is much more relieved now.
“Oh, by the way, in those days when telling our distinguished guests such a big thing, we shouldn’t need certain nutrients, right?”
Hearing this, Luo Feng was puzzled. "What nutritional factors? What do you mean?"
"In other words, in the year 5100, true soilless cultivation can be achieved without some nutritional elements. All it takes is the energy block of nuclear fusion, and If the nutrient solution can keep up, you don’t need soil!”
"Coupled with the unmanned automatic management system I designed, we can produce about five tons of soybeans in one quarter."
After all, Tianyuan Planet has continued to develop.
With certain viruses in the human body, 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.
Plants grown without soil obviously do not have those nutrients, so they need a thin layer of soil.
"Is there such a thing?"
"The relationship is good, it will be more convenient if there is no soil."
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 grids of barracks one after another.”
“As long as nuclear fusion energy is provided, the temperature and humidity inside can be guaranteed.”
“And the emergence of nutrient solution can replace the soil, allowing plants to obtain most of the nutrients in the soil.”
“So, in a place like this, no matter it is There is no need to worry about crops in any season, and there is no need to consider the production loss or nutritional problems caused by the changes in spring, summer, autumn and winter. "Guarantee that the most suitable growing environment for soybeans is at any time."
Luo Feng was slightly moved when he heard this.
No wonder people can produce soybeans three times in one season.
In other words, this thing is a high-tech, upgraded version of greenhouse vegetables.
And such unified management is undoubtedly quite easy for Luo Feng.
However, after seeing this drawing, Luo Feng had a bigger idea and couldn't help but feel a little disappointed.
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 1,200 acres. Since you can build four floors, , then I want to use all 1,200 acres of land 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. New blueprints are available. However, since you have quadrupled the size, I am providing this. The seeds can only be supplied for a relatively short period of time.”
“No problem, about one year is enough.”
Luo Feng chuckled, one year. In that time, Luo Feng estimated that the entire Miaoxiang Kingdom would be cleared out of the surrounding ruins.
Will you be able to find the seeds by then?
"Son, where are you? Are Xiyan and you together?"
After Luo Feng returned to the earth.
When I turned on my cell phone, my father called me.
"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 eating, she listened curiously to her boyfriend's phone call.
After all, this was a call from her husband-in-law, so she still took it seriously.
"Okay, if you two have time, come back and let us see your daughter-in-law, right?"
"I know dad, it's no problem." Luo Feng hehe Smiling, she looked towards Li Xiyan. She seemed to have heard something and her face turned red.
After all, Dad’s voice is really loud when he calls.
You don’t need to turn on the speakerphone, you can still hear some.
"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?"
< br>"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? If soybeans fill the yield per mu of 1,000 kilograms, aren't you just making a joke? I told you, you Dad, I am a respectable person no matter what. If you fail to achieve a yield of 1,000 kilograms per mu by then, you will not only make a fool of yourself, but also make things difficult for those who help you.”
< br>Luo Feng picked at it Ear, "Dad, just wait. I dare not say more, but I can definitely achieve this expectation of a thousand catties per mu. I am not filling it in randomly."
"I can really do it. ? That’s 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, technology As long as this thing is developed, 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 mu?
In the past, in ancient times, one acre of rice in Daxia could produce several hundred kilograms per year, which was pretty good.
And now? Under normal circumstances, the rice yield per mu can reach about 2,000-3,000 kilograms.
Of course, what was the yield per mu in ancient times? In fact, this is really hard to estimate.
Just do the math through ancient books.
"Historical Records: Book of River Canals" says: The Qin Dynasty opened the Zhengguo Canal, "with more than 40,000 hectares of land irrigated and fertilized, and the harvest was one acre per acre."
The yield is also 10 shi per mu.
The so-called "hundred acres" refers to an area of 100 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 0.333 city stones, which translates into 1.524 city stones per mu of millet today. One city stone of millet weighs 135 jins, which means that the yield of millet per mu at that time was 205.8 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 imagined such a high rice yield 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 that her boyfriend was capable, she still wanted to try it herself to see if she could make a name for herself in the industry.
Luo Feng found her idea both cute and unnecessary.
After all, you get the resources yourself, so why not use them?
But if she wants to do this, Luo Feng should respect her choice.
Luo Feng, on the same day, took his drawings back to Hangzhou. 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 look after her, so there won’t be any problems.
His girlfriend, Luo Feng does not want to see being bullied or wronged.
When it comes to safety issues, it is natural to think carefully.
