Chapter 70 Soil Nuclear Radiation

It's dangerous, almost exposed.

It turns out that even soil has become a luxury in the future world!

Maybe everyone will say that such things as soil, even if you live underground, you will still have it.

But in fact, the average thickness of the pedosphere is only five meters, and the lower part is the lithosphere, which is the rock parent material that will take a long time to weather into soil.

Not even the five meters of soil can grow plants. Only the cultivation layer on the surface can be cultivated, and the thickness is about 20cm. Moreover, due to the different organic matter content, their fertility or barrenness is also different.

Under the plow layer is the compact plow bottom layer, which has small porosity, poor ventilation and water permeability, and good water and fertilizer retention. The thickness is only 6-8cm, so the soil from the plow bottom layer, organic matter and its The nutrient content drops dramatically, making it completely unsuitable for growing crops.

And since humans are forced to move underground in the future, it means that the thickness of the soil contaminated by nuclear radiation should be much thicker than this 26-28cm, and even submerge five meters of the pedosphere.

It is reported that the nuclear radiation caused by the leakage of the nuclear power plant in Japan has penetrated 7000 meters underground.

As for the treatment of soil contaminated by nuclear radiation, at present the most effective way is to replace and renovate. Even so, when it is completely eliminated, it is estimated that several generations will not see it.

Theoretically, the soil contaminated by nuclear radiation cannot be eaten within 50 years, and within 100 years, nuclear radiation still exists in the soil.

Therefore, as a master of soil science, Song Yu believes that in the material-poor underground barriers, the soil that can be used for planting is very rare.

Because even if you want to fertilize the soil deep underground with organic matter, you still need so much organic matter, such as straw, organic fertilizer, etc.

And the fertilization time is almost 10-20 years, or even more.

No wonder Song Yu asked Xiaoye before if he had any advanced research data on soil science, and Xiaoye said it was only about 30 years old.

Therefore, people who can use soil to grow vegetables and flowers must be big bosses in the eyes of future people.

In fact, Song Yu doesn't have to deliberately hide that he lives on the ground, as long as people don't know that he is from the past.

But the time is not yet ripe, and I am worried that there will be troubles, and we will wait until we become stronger.

[Xiaoye, I’m going to work hard on you again. Pull out these plants, and divide each plant into several smaller ones to put on the shelves. The price is still 0.1 coins, and each person is limited to one plant. 】Song Yu ordered.

【OK. 】

Within ten seconds, the purslane trees disappeared under Song Yu's feet.

Song Yu thought about raising the price a bit, at least 1 coin per tree, after all, if you buy any tree, it will cost you a lot of money if you sell it.

But thinking that the purpose of my doing this is not to make money, but to make these plants appear in the future, and those who sell the plants are helping Song Yu so that more people can buy them. arrive.

Moreover, my current ability to earn a certain treasure coin is quite strong, there are cooperative companies, and there are rewards, but there are few upgrade coins, so I have to work hard.

He no longer needs to earn coins by selling things. Of course, all the things he sold before, except for a small strawberry for Sensen, were priced at 0.1 coins.

How about so many people guarding his shop.

However, a certain treasure coin is easy to earn, but RMB is not easy to earn.

By the way, it's time to sell the patent, I hope Huangming Solar Energy Company is reliable.

Song Yu took out her mobile phone, found the number of Wu Hong, the manager of Huang Ming Group, and dialed it.

"Hello, is this Manager Wu?" Song Yu asked politely.

"Hello, Mr. Song, are you planning to visit our company?" Manager Wu said straight to the point.

"Yes, but today is the weekend, I'll go tomorrow." Song Yu said.

"Okay, actually I'm also working overtime on weekends, after all, I just took over a big project." Manager Wu said with a smile.

"Then I will trouble you tomorrow." Song Yu said politely.

"It's okay. It's my job. Call me when you arrive."

"Ok."

This manager Wu speaks with the frankness of Shandong people, and he is also a very good person. Song Yu has a good impression of him. As long as the company has no problems tomorrow, it will probably be fine.

I thought of the purslane that had just been put on the shelves, which was probably the result of being killed in seconds, so I didn't watch it.

In other words, it has been dark lately lately, around 06:30 in the afternoon, and the sun is still very bright.

Song's father is ready to cook, just the two of them, one dish is enough, without Song Yu's help.

Song Yu sat under the apricot tree in the yard of his house, dappled sunlight, he took out his phone and turned on the news, and found that many were talking about the Tokyo Olympics.

He couldn't help but think that if his current physical strength represented the country, he should be able to bring back a few medals, such as weightlifting, marathon, cycling, and so on, and he could also be upset.

After playing for a while, Song's father called for dinner, and Song Yu went back to the house.

After dinner, after washing the dishes and tidying up, it was already past 07:30, and the sun was still favoring the earth.

Picking a cucumber at random and eating it as an after-dinner snack, Song Yu began to sit and imagine the scene after his yard was repaired.

It's just that there are a lot of mosquitoes, which is a common problem in rural areas. It seems that the plan to change the dry toilet to the toilet will be put on the agenda when the money is available.

After 10 minutes, the sun finally finished its afterglow reluctantly, and withdrew from this half of the earth.

Then I saw the stars start to twinkle, several famous constellations were embedded in the sky, and a plane flew overhead from time to time.

The melodious singing of crickets came from the vegetable garden, making the yard so quiet.

Hey, there are more mosquitoes, I can't stand it, so I went back to sleep.

Song Yu set off early the next morning. After all, the journey was quite long.

It took nearly 2 hours for Song Yu to get to Sun Valley after taking another bus, and it took him a while to find Huangming Solar Energy Company.

After Song Yu arrived at the door, he called Manager Wu. After all, it wasn't a big leader's inspection, and it didn't need someone to greet him at the door.

"Mr. Song, you're here, welcome." Manager Wu politely shook hands with Song Yu when he came up.

Song Yu hesitated for a moment, stretched out his hand, and said, "Manager Wu, I've delayed your work."

Manager Wu in a suit smiled and said, "Where there, it's my job to win your patent."

Song Yu smiled awkwardly: "The main reason is that Huang Ming's brand has existed since I was a child, and I have wanted to see it for a long time."

Manager Wu stretched out his hand to invite: "Then please come in, let me introduce you."

Afterwards, Manager Wu took Song Yu along and explained. Most of them were the most famous water heater projects of their group, and finally came to the solar power generation project that will be completed soon.

This piece of Song Yu can understand most of what he said, after all, he has recently read the literature for more than half a month.

After the whole process, to be honest, Song Yu was really satisfied, not only with Manager Wu, but also with the entire company, so he decided on Huang Ming.

And if there are similar patents in the future, Huang Ming Group can also be considered first, after all, it is a company that has been investigated.
