"Planting Camu trees?" Sun Jiao was stunned, and then a look of embarrassment appeared on her face.
"Is there a problem? You should be able to buy saplings in the market. If you can't buy them, you can ask Zhou Guoping to think of other ways to get them." Jiang Chen said confused.
"No, it's not the problem with the saplings. The saplings are easy to get rid of." Seeing that Jiang Chen seemed to have misunderstood what she meant, Sun Jiao couldn't help but smile bitterly and said, "The problem is with cultivation."
"Cultivation? I remember that this mutated plant should be able to survive on the soil of the apocalypse. Is there any problem?" Jiang Chen frowned.
Ordinary crops cannot survive in the wasteland, which is polluted by nuclear, biological and chemical weapons, but mutant plants that have adapted through selection and elimination can. Logically speaking, there is no reason why things that can be grown in the Sixth Block cannot be grown in the Fish Bone Base.
Hearing Jiang Chen's question, Sun Jiao couldn't help but raise her forehead, and had to patiently educate him on basic knowledge.
If you want to plant in wasteland, you have to consider two factors. One is the radiation level, and the other is the soil pollution level.
As long as there is material exchange with the outside world, the effects of radiation cannot be avoided. There is nothing in the wasteland that is completely free of radiation, even drinking water that has been treated by automated water purification equipment. It's just that because of EP and special drugs, low-level radiation has no effect on people, but plants are not treated so well.
If you want to prevent the apples grown from mutating, the radiation level must be controlled below 1. If the radiation level is higher than 5, even normal seeds will become abnormal if they fall on the ground. With the technology of the Sixth Block, controlling the radiation level to 3 is already the limit. This can reflect how precious the canned fruits Jiang Chen brought.
However, mutant plants that have survived through natural selection are not that valuable, and their radiation resistance is generally relatively high. Taking the Camu tree as an example, as long as the radiation value is below 40, it can grow normally. The radiation value in most places in the wasteland is between 10 and 20. As long as you are not going to a place like a nuclear crater, the radiation value cannot reach 40.
Soil pollution is relatively easy to solve. After all, soil-free planting technology will be quite mature in the future.
Therefore, plantations in the wasteland can be roughly divided into two types.
One is to use soilless cultivation technology to cultivate crops.
The advantage of this planting method is obvious, that is, the impact of soil pollution can be completely ignored. At the same time, the yield per unit area is also higher than that of soil cultivation. However, its disadvantage is also obvious, that is, the cost of planting is relatively high. The use of soilless cultivation technology to produce industrial raw materials such as Kamu resin will definitely have to be paid to grandma. It is usually used to cultivate some luxury goods, such as fruits that are not completely mutated.
The representative building in the sixth block is the CNC planting tower. Of course. Because of the emergence of canned fruits, this type of industry is on the verge of bankruptcy.
The other is conventional planting on land.
It's simple and crude, just sow seeds, water and fertilize, and the product will be produced. Whether to employ serfs for slash-and-burn cultivation or mechanized dense planting depends entirely on the preference of the landowner, and is mainly used to produce less precious plant variants. For example, Camu resin used in industrial production, such as various flavors of tobacco...
The advantage of this type of planting method is its low cost. However, the requirements for soil quality are somewhat demanding.
Taking the Camu tree as an example, this crop can only be grown if the soil pollution level is less than 10. There are very few such treasure lands in the wasteland, so the production of Camu Resin is not high even in the Sixth Block. Originally there was little demand for these things, but recently the supply has exceeded demand.
"Isn't it okay to buy soilless cultivation equipment?" Jiang Chen asked reluctantly.
"If you use soilless cultivation equipment to grow Camus trees, how many crystals do you have to spend to get a ton of Camus resin?" Sun Jiao said helplessly, holding her forehead.
It's a bit difficult now.
Jiang Chen couldn't help but frown, and fell into deep thought.
But at this moment, he suddenly thought of Lin Ling.
correct! that""!
If it is possible to establish a local biosphere, then there is no reason why there is no technology to improve the soil, right
"Have you thought of anything?" Sun Jiao looked at Jiang Chen's expression in confusion and asked.
"Yes." Jiang Chen raised a smile, "It seems that the 'little slave' we raised in the villa will come in handy."
Sun Jiao understood instantly, and a flash of joy flashed across her face.
... ...
"What? Reduce soil pollution? Why do I have to help you?" Lin Ling said unceremoniously, shaking the test tube with her fingers and covering her disgusted expression with her long, silky hair.
The red and black eyes were the same as before he left. It seemed that she had become accustomed to the life of an abnormal creature living inside her.
"Because you need to eat." Jiang Chen sighed and said matter-of-factly.
He was somewhat tired of seeing that humiliating expression, but this girl seemed to be enjoying it
"I asked, are you feeling lumpy due to being bullied?" Jiang Chen said helplessly, looking at Lin Ling who started writing and drawing on the touch pad with a frustrated look on her face.
She clearly has a face that is not inferior to that of a beautiful girl. He had to put on such a bad expression.
"Go to hell." Lin Ling drew the last stroke with her finger, gave Jiang Chen a fierce look, stuck out her tongue and made a face.
"What is this?" Jiang Chen ignored her movements and asked as he approached the touch pad.
"Haha. Stupid-" Lin Ling puffed up her chest and raised the corners of her mouth.
"Ahem."
"Ah! That's enough! Okay, let me say that's it." Lin Ling pouted her lips in frustration, stretched out her finger and tapped on the screen, "The first step is to neutralize the acidity and alkalinity, and the second step is to neutralize acidity and alkalinity. Use an ion filter to remove heavy metal ions. The third step is... "
"Wait a minute, what is the ion filter?" Jiang Chen stopped her and asked with a headache.
"A thing that can easily filter out a specified relative atomic mass should be very common." Lin Ling said casually.
Damn it, never heard of it at all.
At this time, Jiang Chen suddenly recalled that Lin Ling seemed to have been staying in the research institute, otherwise she would not have any understanding of the situation in the end of the world. In this way, the "common" in her words probably means that it is very common in the laboratory.
Misstep...
"Let me ask first, how many steps are there in these processes you mentioned?" Jiang Chen asked with black lines on his head.
"No more, no more, just 24 processes. I took samples of the soil here and tested it, and the pollution degree is 68. It's unbelievable that weeds can grow in such poisonous soil." When talking about her areas of expertise, Lin Ling The expression on his face also became excited.
"Don't you consider the cost when you are tinkering in the laboratory?" Jiang Chen complained.
"Cost? Of course we will consider it." Lin Ling said disapprovingly.
"After you have gone through more than 20 processes, tell me what the cost is?"
Lin Ling gave Jiang Chen a strange look.
"Did you misunderstand something? The "Eden Project" is not a 'soil purification plan'. Since it is a sub-project of space colonization, why do we have to study how to control earth pollution. Using organic matter and minerals from other planets, we It’s completely possible to create soil, but purifying it is too troublesome.”
"Making soil?"
"Yes, making soil is not difficult, at least it is much easier than washing the ground. However, there are contaminated 'finished products' everywhere here, and it seems not easy to find pure raw materials for synthetic soil." Lin Ling sighed. Take a breath.
Making soil? Other planets
Jiang Chen suddenly slapped his head and cursed secretly in his mind.
Damn it, why didn't I think of that? Why bother? I can travel both ways! If you can move food back, how difficult is it to get hundreds of cubic meters of mud
Now that the problem has been solved, Jiang Chen didn't intend to continue the problem anymore, so he changed the topic.
"Okay, let's not talk about this for now... By the way, have you completed the task assigned to you?" (.)
