I Have a Mansion in the Post-apocalyptic World

"Growing the Cam Tree?" Sun Jiao stunned, and his face immediately showed a touch of color.

"Is there a problem? If the saplings should be available in the market, if you can't buy them, let Zhou Guoping think about other ways to get it." Jiang Chen did not understand.

"No, it is not a problem of saplings, the saplings are very good." Seeing Jiang Chen seems to have misunderstood her meaning, Sun Jiao could not help but smile, "The problem is cultivation."

"Cultivate? I remember that this mutant plant should survive on the soil of the last days. Is there any problem?" Jiang Chen frowned.

Ordinary crops cannot survive on the waste soil, which is contaminated by nuclear and biochemical pollution, but it is possible to choose to replace the adapted plant. It stands to reason that the things that can be planted in the sixth block, the fish bone base can't be planted.

Upon hearing Jiang Chen’s problem, Sun Jiao couldn’t help but support her. She had to patiently and basic knowledge with him.

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

As long as there is material exchange with the outside world, the effects of radiation cannot be avoided. There is no such thing as no drinking water at all on the waste soil, even if it is treated by automated water purification equipment. Only because of the presence of ep and special drugs, low levels of radiation have no effect on people, but plants are not so good.

If you want to make the apples do not mutate, you must control the irradiance below 1. If the irradiance is higher than 5, even if the normal seeds fall into the geography, they have to become abnormal. With the technology of the sixth block, it is already the limit to control the irradiance at 3. From this point, it can be reflected that the canned fruit brought by Jiang Chen is precious.

However, the surviving mutant plants that are eliminated from the natural selection are not so expensive, and the radiation tolerance is generally high. Taking the Cam tree as an example, the radiation value can grow normally as long as it is lower than 40. Radiation values ​​in most places on waste soil are between 10 and 20. As long as it is not the place to go to the nuclear crater, the radiation value is unlikely to reach 40.

The soil pollution degree is relatively good to solve a little, after all, the soil planting technology is quite mature in the future.

Ever since, the plantations on the waste soil can be roughly divided into two types.

One is to use soilless cultivation techniques to grow crops.

The benefits of this type of planting are obvious, that is, the effects of soil pollution can be completely ignored. At the same time, the output per unit area is also higher than that of soil cultivation. However, its shortcomings are also obvious, that is, the cost of planting is higher. The use of soilless cultivation techniques to produce Camm resin, an industrial raw material, is definitely worth the loss of home, usually used to cultivate some luxury goods, such as the variability of not completely fruit.

The representative building in the sixth block has a CNC planting tower. Of course. Because of the emergence of canned fruit, such industries are on the verge of bankruptcy.

The other is conventional planting on the land.

Simple and rude, sprinkle seeds and water to fertilize to produce products. Whether it is the employment of serf knives or mechanized dense planting depends on the preferences of the landowners, mainly used to produce less expensive plants. Such as Kam resin used in industrial production, such as tobacco of various flavors

The advantage of this type of planting is the low cost. However, the demand for soil is somewhat harsh.

In the case of the Came tree, the crop can only be grown if the soil pollution level is less than 10. Such treasures are very rare on waste soil, so the production of Cam resin is not high even in the sixth block. Originally, these things were originally in short supply, but in the recent period, they have been in short supply.

“Is it not good to buy soilless cultivation equipment?” Jiang Chen asked reluctantly.

"Use the soilless cultivation equipment to plant the Cam tree, then how many sub-crystals you have to spend to get a ton of Kam resin." Sun Jiao Fufu helpless.

This is a bit difficult to do.

Jiang Chen’s brow could not help but screwed up and fell into meditation.

But at this moment, he suddenly thought of Lin Ling.

correct! That "Eden Project"!

If you can do it even with a local biosphere, it doesn't make sense to improve the soil technology.

"What did you think of?" Sun Jiao looked confusedly at Jiang Chen, who was constantly changing his face, and asked.

"Yeah." Jiang Chen’s mouth raised a smile. "It seems. The 'small slaves' raised in our villas will come in handy."

Sun Jiao knows, his face is flashing a touch of color

"Hey? Reduce the soil pollution? Why do I have to help you?" Fingers squeezed the test tube and shook, the soft silver long hair blocked the disgusting expression, Lin Ling said unceremoniously.

The two red and black eyes are the same as before when he left. It seems that she is used to living in an unusual creature.

"Because you need to eat." Sighed, Jiang Chen said of course.

The humiliating expression, he is somewhat tired of watching, but this chick seems to be happy?

"I said, are you being bullied and coming out of the block?" Looking at Lin Ling, who was frustrated and began to write on the touchpad, Jiang Chen said helplessly.

It is clear that there are faces that are not lost to beautiful girls. I have to make such a bad expression.

"Go to hell." Finger painted the last stroke, Lin Ling murdered Jiang Chen, and made a face.

"What is this?" Jiang Chen ignored her movements and asked for it on the edge of the touchpad.

"Oh. Stupid" Lin Ling stood up and raised her mouth.

"Cough."

"Ah! It's enough! Ok, I'm fine." Frustrated and picked up the small mouth, Lin Ling put her finger on the screen. "The first step is pH neutralization, the second step is The ion filter removes heavy metal ions. The third step is"

"Wait, what is the ion filter?" Jiang Chen stopped her and asked her head.

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

Lying in the trough, I have never heard of it.

At this time, Jiang Chen suddenly recalled that Lin Ling seems to have been staying in the research institute, or she will not know anything about the situation in the last days. In this way, her mouth is common, I am afraid that it is very common in the laboratory.

Mistaken

"I asked first, how many steps did you have to say about these processes?" Jiang Chen asked with a black line.

"There are not many, so there are 24 procedures. The soil here has been sampled and tested, and the pollution degree is 68. Unbelievable, such poisonous soil can still produce weeds." When talking about the areas she is good at, Lin Ling The expression on my face has also become very interesting.

"When you slam the drums in the lab, don't you consider the cost?" Jiang Chen spit out.

"Cost? Of course, I will consider it." Lin Ling did not think so.

"You have so many processes, you tell me what the cost is?"

Lin Ling looked at Jiang Chen with a weird look.

"Are you misunderstood? 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. With organic matter and other minerals on the planet, we It is completely possible to make the soil, and it is too much trouble to purify anything."

“Make the soil?”

“Yes, it’s not difficult to make the soil, at least it’s much easier than washing the land. But there’s a 'finished product’ that has been polluted everywhere. It’s not easy to find the raw materials of pure synthetic soil.” Lin Ling A tone.

Making soil? Other planets?

Jiang Chen suddenly took a picture of his head and whispered in his heart.

In the trough, I never thought about it. Why are you so troublesome, I can cross on both sides! Food can be moved back, how hard is it to get hundreds of cubic meters of mud?

Since the problem has been solved, Jiang Chen does not intend to continue this problem, so he opened the topic.

"Well, let's not say this right, and the task handed over to you is not finished." (To be continued.)
