After the end of the world, the land was so polluted that no crops could be grown, but the people of the New Age did not give up, and for hundreds of years, generations of people worked tirelessly to restore the land to life. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

“…… Under the New Land Law, the people of each continent had the responsibility and obligation to reclaim wasteland and purify scorched earth. Juan was wearing a bright gray-brown casual pants, leading Hua Qianyan and Fat Ball, and explained slowly as he walked: "Especially the people of the free zone, they must do their best to transform the scorched earth. For, according to the provisions of the New Civil Law, in the free wasteland of the free zone, the wasteland reclaimed by each subject is owned by the individual and is regarded as private property. ”

Hua Qianyan listened while casually looking around. This is the outlying area of the town, the so-called wasteland. The path at the foot of the road separates the town from the wasteland: on the north side of the path is a residential area with a dozen houses scattered in between, and on the south side of the path is a deserted area, and from the side of the road, a dull yellow, obscure scorched earth stretches to the junction of the sky and the horizon, without the slightest trace of green.

To be honest, Hua Qianyan couldn't tell which piece of land had been reclaimed at all, and she interrupted suspiciously: "Wait a minute, what is the reclaimed wasteland? I just looked at it, the land here is basically the same, there is no trace of ploughing, and there is no crop planting." ”

It is not at all different from the spring ploughing scene seen in the previous life, here, to put it mildly, it is still an inland area, it is clearly a big desert, the only difference is that the soil here is quite firm, and there is no desert that is full of wind and sand.

"Hehe, of course there are standards. Juan saw the confusion in Hua Qianyan's eyes, led them to a trapezoidal field on the side of the road, grabbed a handful of gravel, and held it in front of Hua Qianyan, "You touch it, are these gravels more delicate than those on the north side of the road?"

Hua Qianyan spread out her right hand, took some gravel, and twisted it with her hand. In his heart, he also quietly asked the system: "What kind of soil is this? Which is better than the scorched earth on the mountain yesterday? Also, can this kind of soil be planted directly with turnips?"

If she remembers correctly, the system has rated the sand on the mountain as 'Grade 2 wasteland'.

"The first-class wasteland, with almost no toxic minerals, is rich in nutrients and water molecules, and has no source of life for the time being, so it can be planted directly with crops. ”

The system is very conscientious and answers the questions one by one in an orderly manner: "This wasteland is better than the wasteland found yesterday, and it is a soil resource that can be directly used, and it can be used to grow radishes, but it requires more energy sources." ”

OK, got it.

Hua Qianyan nodded and said to Juan, "Well, it seems to be a little damp. How did this 'reclaim'?"

At this time, Hua Qianyan can be sure that Juan's so-called 'reclamation' is not the same concept as the reclamation in the previous life. More precisely, in the new age, this act should be called 'purification'.

"Well, it's a complicated and long process. The first step is to use an instrument to survey the harmful substances in the soil, determine what the pollution is, and then purify it with the corresponding purification solution. In the second step, the specially configured nutrient solution is evenly sprinkled into the soil to artificially increase the nutrient content of the soil. The third step is the traditional plough to sort out the soil. After completing these three steps, all you get is the dirt in your hands. ”

"So you can plant?" Hua Qianyan could basically understand the principle of these steps, she threw the broken soil in her palm back into the field, gently patted the sand on her hand, and asked curiously: "But why is there nothing planted here?" Is there no seed?"

Yes, in the last days, all kinds of natural disasters and H viruses have almost destroyed the green life on the earth, flowers and trees have been exhausted, and fruits and seeds are estimated to have been wiped out.

"Of course not, but it's not that there are no seeds, but that natural conditions don't allow it," Juan also stood up, rubbed his hands on his trouser legs casually, looked at the barren fields in the distance, and said lightly: "After doing the three steps just mentioned, it only temporarily restores the soil for planting crops, and it can't be planted directly." As I said earlier, this reduction is only temporary, and the nutrients in the soil are also artificially added, which is simply not enough to support the whole process of natural growth and maturation of crops. Therefore, such soil cannot be used to grow crops directly.

In addition, due to the impact of the end times, the environment of the new era has been devastated, which not only the soil has been polluted, but also the groundwater and air have been polluted to varying degrees, and even after hundreds of years of purification, it still has not been able to solve the fundamental problem. If crops are planted directly in the wild, an acid rain can burn them all. ”

Speaking of this, Juan led Hua Qianyan and the fat ball, and continued to walk forward, walking for about ten minutes, he pointed to a circular object suspended in mid-air not far away and asked, "Do you see the sky glass greenhouse in front of you?" This is the sky vegetable garden in our town. The inhabitants of each town must regularly deliver a corresponding amount of purified dirt to it, oh, the same amount of dirt we just saw. ”

Hua Qianyan followed his fingers and looked over, and sure enough, not far ahead, in mid-air two or three meters from the ground, there was an oval glass sphere suspended, and if you looked closely, there were many small dots of red, red, green and green in the sphere.

She nodded, "See, this, this is the vegetable garden in the sky?"

Hua Qianyan's eyes flashed with excitement, and she couldn't help but blurt out a weak question for a while: "Eh, this thing is suspended in mid-air, it won't fall, right?"

"Hey, hillbilly!"

As soon as Hua Qianyan's words fell, a mocking laugh came from behind him.

Before Hua Qianyan could turn around, a woman in a pink glossy dress came out from behind, looked Hua Qianyan up and down with disdain, and said coldly: "Old fox, where did you get such an old hat? It can't be from that gathering area, right? I haven't even seen a vegetable garden in the sky?"

"Ah Lian, what are you talking nonsense?!" Juan glanced at the woman in pink unhappily, and then introduced to Hua Qianyan with a smile: "Come, let me introduce you, this is Mu Lian, the staff of the aerial vegetable garden, and the assistant to the director." Ah Lian, this is Hua Qianyan from another dimension, she just arrived in our town yesterday, and she has settled in the town since then, and she is also our neighbor. ”

Mu Lian had no intention of greeting Hua Qianyan at all, she didn't look at her, tilted her head, snorted, and walked straight ahead.

“…… Hehe, Ah Lian has a weird temperament, but she is actually very kind. Seeing that Mu Lian was so faceless, Juan was not angry, smiled wryly, and explained to Hua Qianyan in a whisper embarrassedly.

Eccentric?

What's weird, people clearly look down on themselves, and think she's an uninformed hillbilly.

However, Hua Qianyan saw that Juan looked a little sorry, and she didn't want to be angry at him, so she smiled indifferently and said, "It's nothing, it's normal for such a beautiful girl to be arrogant." ”

Fat Ball snorted coldly, and said unceremoniously: "Hmph, what arrogance, it is clearly arrogance, is she the daughter of the mayor's family, so dragged?"

"No, it's mainly in our New World, and the staff who are good at agriculture are more respected, so-"

Juan wanted to cover up this matter with a haha, and he was even more thinking in his heart, well, should I take them to visit the aerial vegetable garden?

You know, compared to the head of the vegetable garden, Mu Lian's little temperament is already approachable, if you talk about arrogance, that wood ability master is the real arrogance.

PS: Hehe, on the first day of March, please support you!
