I! Billions of invincible identities

The group continued to get busy again, and the scientists who were originally in the research institute planted vegetables here. They didn't feel any difference in identity, but they felt very happy.

These vegetables were all grown on the moon, and they all grew them themselves. Now I see that the seed of a vegetable actually started to sprout. This makes their hearts naturally very happy and very accomplished.

"The moon can be used as a second living point for mankind. At least for now, there is no discomfort. Now that vegetables have been planted, it is not easy to find a suitable place to plant trees. Did you find this little day when you were monitoring? "

Yang Fan asked Xiao Tian beside him.

Trees are not the same as vegetables, as long as there is a thin layer of soil, vegetables can take root and sprout in the soil. But for trees, the root system inside is too luxuriant. It's just a shallow layer of soil, which is simply not enough for big trees to take root and sprout in it.

So building trees on the moon needs to be replanned.

"As far as the current tests are concerned, the soil above the moon has not yet exceeded 30 centimeters thick. Completely unsuitable for planting trees. Unless it is artificial breeding

Xiao Tian said on the side. "And there's no water in the moon's surface layer. Even if the trees are planted, the trees only desperately take root down, but they cannot draw any water. "

Listening to Xiao Tian's words, Yang Fan could be regarded as reacting. Planting trees is not such a simple thing. After all, there is no groundwater here.

"It seems that we still have a long way to go! I'm sure this day will come. I think we can choose to accumulate the soil. Plant one or two first to see the effect. "

Yang Fan did not give up planting trees and was interested. The more difficult it is, the more I feel that this is a challenge and an opportunity.

Besides, Yang Fan is waiting to go to the next planet to explore. If he didn't settle the moon, he would never want to go to the next planet.

"When the next ship comes up, let them bring a few saplings with them. Do some experimental cultivation first. After success, we will cultivate on a large scale. "

Yang Fan had already made up his mind and made up his mind.

Now their biggest problem is simply because there is no soil and no moisture. Even Yang Fan felt that he might be able to pull some soil from the earth. How is the soil on Earth different from the soil on the Moon? And will the soil on Earth be assimilated after being put on the moon?

If it can be assimilated, as long as there is time, Yang Fan will definitely let the spacecraft bring some soil up. Increasing the thickness of lunar soil is definitely a good idea.

After finishing busy in the shed, Yang Fan and the others also began to walk towards the City of Steel. Not only a few of them came to the moon, but also a hundred volunteers.

Now the matter here in the vegetable greenhouse can come to an end, just wait for the vegetables to sprout and take root. Yang Fan, on the other hand, felt that he could have an exchange with those volunteers. It seems that what exactly is it like for them to live on the moon?

At the same time, he also drew some shortcomings from their mouths so that Yang Fan could improve the moon.

Otherwise, he would not have been able to fund and let so many volunteers come and experience life.
