Chapter 175

"Plant Camus trees?" Sun Jiao was stunned for a moment, 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, let Zhou Guoping think of other ways to get them." Jiang Chen puzzled.

"No, it's not about the saplings. The saplings are easy to grow." Seeing that Jiang Chen seemed to have misunderstood what she meant, Sun Jiao couldn't help but smiled wryly, "The problem is the cultivation."

"Cultivation? I remember that this mutated plant should be able to survive on the soil of the last days. Is there any problem?" Jiang Chen frowned.

Ordinary crops cannot survive on the wasteland, which is contaminated by nuclear, biological and chemical substances, but the mutant plants that have adapted through selection and elimination can. It stands to reason that what can be grown in the sixth block, there is no reason why the fish bone base cannot be grown.

Hearing Jiang Chen's question, Sun Jiao couldn't help rubbing her forehead, so she had to patiently educate him about the basics.

If you want to plant on waste soil, you have to consider two factors. One is radiation, and the other is soil pollution.

As long as there is material exchange with the outside world, the impact of radiation cannot be avoided. There is nothing in the wasteland that does not contain a little radiation, even the drinking water that has been processed by automatic water purification equipment. It's just that because of the existence of EP and special drugs, low-level radiation has no effect on humans, but plants are not treated so well.

If you want to keep the planted apples from mutating, you must control the irradiance below 1. If the radiation level is higher than 5, even normal seeds will become abnormal when they fall on the ground. With the sixth block's technology, controlling the radiation level to three is already the limit. This can be reflected from the side. The canned fruit that Jiang Chen brought was so precious.

However, the mutated plants that survived the elimination of natural selection are not so expensive, and generally have higher radiation resistance. Take Camus trees as an example. As long as the radiation value is lower than 40, it can grow normally. The radiation value in most places on the wasteland is between 10 and 20. As long as you don't go to a place like a nuclear crater, the radiation value cannot reach 40.

Soil pollution is relatively easy to solve. After all, the technology of planting out of the soil is quite mature in the future.

Therefore, the plantations on the wasteland can be roughly divided into two types.

One is to use soilless culture techniques to grow crops.

The advantage of this planting method is obvious, that is, the impact of soil pollution can be completely ignored, and the yield per unit area is also higher than that of soil planting. However, its disadvantage is also obvious, that is, the higher cost of cultivation. The use of soilless cultivation technology to produce industrial raw materials such as kamu resin must be paid to grandma's house, and 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 NC Plantation Tower. Of course, with the advent of canned fruit, the industry was on the verge of bankruptcy.

The other is conventional planting on land.

Simple and rude. Sowing seeds, watering and fertilizing can produce products. Whether to hire serfs for slash-and-burn farming or mechanized dense planting depends on the preferences of the landowners, and it is mainly used to produce less expensive mutant plants. Such as kamut resin for industrial production, such as various flavors of tobacco

The advantage of this type of planting method is that the cost is low, but the demand for soil quality is somewhat harsh.

In the case of Camus trees, this crop can only be grown if the soil pollution level is below 10. There are very few treasure lands like this in the wasteland, so the output of kamu resin is not high even in the sixth block. Originally, there was no demand for these things, but recently, the supply has been in short supply.

"Isn't it okay to buy soilless cultivation equipment?" Jiang Chen asked unwillingly.

"Using soilless cultivation equipment to grow kamu trees, how much subcrystal will you have to spend to produce a ton of kamu resin." Sun Jiao said helplessly while holding her forehead.

Now it's a little difficult.

Jiang Chen couldn't help frowning, lost in thought.

But at this moment. He suddenly thought of Lin Ling.

correct! That "Eden Project"!

If it is possible to even establish a local biosphere, there is no reason why there is no technology to improve the soil, right?

"Did you think of anything?" Sun Jiao looked at Jiang Chen whose expression was constantly changing, and asked in confusion.

"Yeah." Jiang Chen smiled, "Looks like the little slaves raised in our villa will come in handy."

Sun Jiao understood in seconds, and a look of joy flashed across her face

"What? Reduce soil pollution? Why do I have to help you?" Fingers pinched the test tube and shook it, and the long, silky silver hair blocked the disgusted expression. Lin Ling said bluntly.

The red and black eyes were the same as before he left. It seemed that she was used to the life of an abnormal creature living in her body.

"Because you need to eat." Sighed. Jiang Chen said it as a matter of course.

He was somewhat tired of seeing that humiliating expression. But this chick seems to be enjoying herself?

"Let me tell you, do you feel like you've been bullied?" Jiang Chen said helplessly, looking at Lin Ling who was starting to write and draw on the touchpad with a dejected expression.

She obviously has a face that is not inferior to that of a beautiful girl, but she has to put on such a nasty expression.

"Go to hell." After drawing the last stroke with her fingers, Lin Ling gave Jiang Chen a fierce look, and made a grimace with her tongue out.

"What is this?" Jiang Chen ignored her movements and leaned over to the touchpad and asked.

"Hehe, stupid—" Lin Ling puffed up her chest and raised the corners of her mouth.

"Ahem."

"Ahhh! That's enough! Well, let me say it." Lin Ling pouted her lips in frustration, and pointed her finger on the screen, "The first step is to neutralize the pH, and the second step is to use The ion filter removes heavy metal ions, the third step is "

"Wait, what is an ion filter?" Jiang Chen stopped her and asked with a big head.

"A thing that can easily filter out the specified relative atomic mass should be very common." Lin Ling said casually.

Damn, never heard of it.

At this time, Jiang Chen suddenly recalled that Lin Ling seemed to have been staying in the research institute, otherwise she would not have no understanding of the situation in the end times. In this way, the common in her mouth probably means that it is very common in the laboratory.

Mistake

"Let me ask first, how many steps are there in the process you mentioned?" Jiang Chen asked with black lines all over his head.

"Not too many, just two or four processes. I have sampled and tested the soil here, and the pollution level is 68. It's unbelievable that such poisonous soil can still grow weeds." When talking about her field of expertise, Lin The expression on Ling's face also became excited.

"Don't you consider the cost when you're tinkering in the lab?" Jiang Chen complained.

"Cost? Of course I will consider it." Lin Ling said disapprovingly.

"After you have completed more than 20 processes, tell me what the cost is?"

Lin Ling gave Jiang Chen a strange look.

"Have you misunderstood 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 the pollution of the earth. Using organic matter and minerals on other planets, we can completely It’s too troublesome to make soil and purify it.”

"Making soil?"

"That's right, it's not difficult to make soil, at least it's much easier than washing the ground. However, there are polluted finished products everywhere, and it doesn't seem easy to find pure raw materials for synthetic soil." Lin Ling sighed .

Make soil? another planet?

Jiang Chen suddenly patted his head and cursed inwardly.

Fuck, why didn't I think of that. Why is it so troublesome, I can cross both sides! The food can be moved back, how difficult is it to get hundreds of cubic meters of mud?

Now that the problem has been solved, Jiang Chen doesn't intend to continue*u this problem, so he changed the subject.

"Okay, let's not talk about this for now, have you completed the task assigned to you?" Please delete the content that is in conflict with national laws, and our position is only committed to providing a healthy and green reading platform. 【】,thank you all!
