The talented people in Jiangshan have put together a variety show

After the program team felt that it was not too much, they directly took people to the harmonious and friendly space plant cultivation base.

The person in charge this time is of course a researcher at the cultivation base.

This female researcher looked very young, her behavior and conversation were decent, and her appearance was even more beautiful than expected.

In fact, most of the researchers in this emerging industry research are relatively young.They are the new force of scientific research in this field, and also the hope of future scientific research.

With a high ponytail tied behind his head, the researcher took four people to visit the laboratory seriously: "Our space plant cultivation base has many kinds of daily work. To explain in layman's terms, part of our research is how to use Growing plants in a space environment; part of it is to study the utilization of excellent genes after the mutated plants in the space environment return to Earth."

He Jun understood the meaning once he heard it: "That is to say, part of it is to study planting in space. The main purpose is to enable people living in space to eat fresher vegetables. It is also for the convenience of living in space in the future. The other part is genetics. Research on mutated plants. For example, mutated oversized fruits and vegetables.”

The researcher responded: "That's right."

She was very happy that the four artists she received were very good at communicating and could understand the content: "In fact, we have already started research in this area in the 90s. The land is of great significance to us."

Qiu Feng paid attention to the news: "The soil on the moon is not suitable for growing vegetables, which disappointed many people at that time."

The researcher smiled: "That's right. The lunar soil itself lacks the organic components needed for plant growth, so it can't grow vegetables. But now through certain changes, the lunar soil can indeed be used to grow vegetables. Of course, whether it can be grown and whether it is necessary Kind of, that's two questions."

Lei San was taken aback: "What do you mean?"

Zhu Yi next to him slapped him: "Put it on, you put it on again. If the lunar soil can be developed for more valuable uses and you use it for farming, will you waste it? Don't they count as transforming the soil and directly transporting the soil?" Go up, which one is more cost-effective?"

Qiu Feng knows a lot: "It doesn't have to be soil, it can be hydroponics."

The barrage was amused by the two: "Hahaha, I just didn't realize it all at once! Why are you talking about people's decorations!"

"What's wrong with the acting? Forgot the lines, log out!"

"Chang Tian Tian Tian! I don't care, I don't care! I want to watch Zhong Tian!"

Danmaku is very active in farming, and Qiu Feng is also very active in farming.

Qiu Feng was born in the countryside and lived with his grandmother.His dream at a young age was to make life easier for his family, so he went to the big city to work hard.I was only 13 years old when I joined the group.

Now as a restaurateur, he is of course interested in farming and fruit and vegetables.

Qiu Feng asked the researcher: "What kind of planting have we tried now? How about the ones in the sky? What about the ones on the ground?"

The researcher said patiently: "There are many kinds. We first did short-term in-orbit cultivation experiments of cypress and rice, and later we have Arabidopsis, tomato, lettuce, potato, etc. The main consideration is edible. Like flowering Ornamental plants, we will study and cultivate less, because these plants have greater demands on the environment, but their practicality is not so high."

In addition, the cultivation environment requires large vegetables, and they rarely choose to grow them in space.

But rarely does not mean none.

On the way leading them to the laboratory, the researcher explained in more detail: "All countries have related research in this area. The colors of fruits and vegetables grown in space will be different due to the different colors of light. There will also be people who specialize in planting Red vegetables. Of course, green ones are more in line with human aesthetics. By the way, some astronauts will plant apple trees in space. As long as they have an idea, every astronaut will try their best to realize this idea."

He Jun listened and felt the infinite pursuit of space.

People have been dreaming of going to the moon.In ancient times, Chang'e flew to the moon, and now there is Chang'e's lunar exploration project.Man wants to farm in space, and now that's what's being done.

In the laboratory, the researchers did not relax their explanations.

There are many instruments in the laboratory, and it is a little different from the traditional planting research laboratory.He Jun has worked in the Rice Research Institute, so he understands this difference more clearly.

In the research of aerospace technology, there are many factors that need to be considered.And these factors are things that hardly need to be considered when planting in the ground.

For example, the researcher said now: "Because of the limitations of space farming, the first thing we need to consider is the edibility of food. Like rice cultivation. We need water, followed by sunlight, followed by drastic temperature changes, and prevention radiation protection."

These problems are too fatal.

In addition to bringing the water for people to drink in space, there are also various human physiological water recycling.It is quite extravagant to use it on plants.But if you think about it carefully, all the equipment used on plants is quite extravagant.

Today's high costs are all for reducing costs in the future.

In addition to water, it is necessary to consider sunlight.The sun is a star, and plants on the earth can feel the sunlight and grow normally.It's very different in space.

If the planting location is indoors, it is often necessary to rely on LED lights.It is impossible for the light of the stars to break through the opaque equipment and shine on the plants.And if you are by a window or in a space laboratory, you can find a way to use sunlight or the light refracted from the moon.

Simply water and light will take a lot of research and experiments.

He Jun was still thinking: "Then there should be research on bacteria and insects, right?"

As soon as the researcher heard it, he knew that He Jun knew something.She cast her approving gaze: "Indeed. There is a relatively stable ecological environment for planting plants on the earth. In space, the projects we are going to study at the beginning must be plants with simple ecological environments. But we will study in the future. The ecological environment is complex. It is best to keep plants in a stable ecological environment that can cycle themselves in space."

Space research should not only study the cultivation of plants during spaceflight.The cultivation of plants on other planets will also be considered.Harmful pests are indeed not suitable for plant growth, but there are many beneficial insects in this world that can promote plant growth, and some even play an indelible role in the growth of some plants.

"We have studied fruit flies. We have also studied barley worms. It depends on what plants we send up." Fruit flies are closely related to plants, and barley worms are because they can supplement protein to the human body.

At this point, everyone's interest gradually shifted.

Lei San and Zhu Yizheng did not study botany.Both are curious babies.

Lei San asked: "We still have to study bugs? When will we study animals?"

Zhu Yizheng answered: "It is necessary to ensure that animals can fly to outer space and successfully adapt to the environment of outer space. If mammals are similar to humans, they should suffer from the same problems."

Can't animals wear space suits like humans?

And Zhu Yizheng's curiosity about plants is: "The vegetable with red leaves is lettuce. I saw it in the news. Can we simulate planting this?"

The researcher nodded of course: "Yes. This growth cycle is short. After I tell you the necessary conditions, you can also try to grow it at home. Lettuce is a kind of plant that is easy to grow."

Not only is it easy to grow, but it can also be eaten directly.Lettuce tastes good when eaten raw, and more people eat it raw abroad.

She also reminded: "If you grow it yourself, the environment where the lettuce is actually not a space environment, so the situation is different. After all, there is no way to cause weightlessness at home."

The four nodded in unison.

The barrage is happy: "Laughing, although it is the same planting, it is a virtual space planting."

"(Gootou) We can grow lettuce on the plane. It's just a bit costly for the pilot and the plane."

"Growing lettuce on an airplane is laughable, and it's a bit costly for the growers."

When we arrived at the experiment site, someone soon brought up the materials that had been prepared.In order not to affect the normal work of the laboratory, the shooting location is an additional room, completely separated from the experimenters.

The lettuce planting that everyone imagined also appeared in front of the camera.

The researcher lady took out a very interesting square box, which was divided into pieces, like a toy.She explained to four people: "We are in space, no matter whether it is soil cultivation or hydroponics, we can't let the soil or water fly around. Therefore, it must be relatively sealed. If you are a gardener, you should know better, there is a magic weapon called vermiculite. "

He Jun and Qiu Feng understood instantly, and looked at each other a little excitedly.

They used vermiculite to grow flowers in the Happy Farm Variety Show.Vermiculite, which is often used in this gardening, absorbs water very well.So it can be used as soil to some extent.

Qiu Feng raised his hand: "I know this, I will. The water is placed at the bottom, and the vermiculite can absorb water upwards, and it will not cause the water to run around. It is enough to bring sufficient water to the plants."

The researcher nodded: "Yes, it can also absorb water downwards, and it is very light in weight, so it can be easily brought into space. So we will consider using this material to participate in the planting process when planting in space."

"Our culture box is 3D printed. The material is also relatively light." She joked, "Everything is to reduce weight."

Everyone laughed out loud.

The researcher continued: "After the vermiculite is put inside, we can sow seeds. The seeds are very small and easy to fly randomly. Therefore, when we first studied, we chose a membrane that would rupture when exposed to water. The outside of the seeds. This will enable the seeds to be successfully sown into the vermiculite without flying around. But later we found that this method will affect the growth of the plants, so we are still improving.”

Affecting growth is a big problem.

But even if it affects growth, it's safer than tiny seeds flying around in space.

The researcher saw that everyone was interested, and put the square box in front of everyone: "The growth cycle of lettuce is exactly one month. It is very suitable for a short-term planting research during space operations. It also has a very good regulating effect on the mood of astronauts. Of course, you If you're going to have red lettuce, maybe the lighting won't be very kind."

The four of them immediately realized the actual meaning of the researcher's euphemism.

Growing vegetables all over the world is red light, not only is it unfriendly, it is simply anti-human.
