The talented people in Jiangshan have put together a variety show

When humans paint the sun, they always like to use red and orange to paint.But this does not mean that red light is needed when planting.Daily lighting does not seem to be red at all, and even the sunlight is pure and transparent white.And when it rains or runs into water droplets, it becomes colorful, and the color spectrum belongs to the rainbow color spectrum.

Zhu Yi threw the pot at Lei San on the spot: "It was he who said he wanted to grow red leaf lettuce."

Lei San asked Zhu Yizheng back: "Aren't you tempted?"

The smart Qiu Feng said: "Don't you think that the researcher was able to take out the props so smoothly, maybe he wanted us to grow red leaf lettuce?"

He Jun sees through the program group even more: "I think the program group has colluded with the researchers. They are leading us to run down this road."

Having said this, the researcher is not a professional actor after all, so he couldn't help but smile.

This smile fully represents: I really know about it, I really prepared the materials, and I really intend to let everyone experience something different.

Barrage: "Who predicted whose prediction!"

"Captain: See Through.jpg"

"Program group: Oh, between us and the captain, there must be only one winner!"

This meaningless speculation did not have any impact on the results of the scene.What should be planted still has to be planted, and what should be worked hard still has to be worked hard.

The researcher affirmed the variety of seeds: "In the few bags of seeds we prepared, there are ordinary lettuce seeds and red leaf lettuce. You can choose the variety you want to plant."

He Jun continued the conversation along the topic: "So how do we grow this lettuce?"

"The two types of lettuce are different, and the daily light required will also be different. Let me talk about the problem of lighting." The researcher lady said with a smile, "We normally grow in space, and the lettuce is provided with red, blue and green lights. Among them, the red light will be more, and the green light is more friendly, which is convenient for frequent observation. For red leaf lettuce, it is more suitable to use blue-violet light, so that the red leaf lettuce will grow better."

Blue-violet light doesn't sound very friendly.

It’s okay for a person to watch blue-purple light once in a while, but if he watches blue-purple light for a long time, he will always feel like he’s dancing in space.

He Jun knew a little about this, but he didn't know much, so he was surprised: "I thought it was mainly red light, after all, red leaf lettuce."

After being surprised, he realized by himself: "I almost forgot that although the leaves of plants are green, they don't really like green light."

The researcher smiled and popularized the relevant content: "Yes. Because plants contain a lot of chlorophyll, they absorb more red and blue light in natural light. Like flowers, their pigments are produced because flowers contain more chlorophyll. Anthocyanins. Pure green light does not allow them to perform sufficient photosynthesis."

In fact, this knowledge has been learned in school days, but adults have almost returned this basic content to teachers.

Lei San and Zhu Yi were having an exaggerated conversation on the sidelines.Lei San covered his mouth: "Really? I thought I was going to turn on the red light for a month this month."

Zhu Yizheng: "I actually hate green the most! I'm going to give them a green light all the way!"

The four of them made jokes, and the staff next to them provided large bags of vermiculite and large bags of lettuce seeds at this moment.After seeing the seeds, everyone realized that the size of the seeds was completely different from that of common seeds.

A packet of lettuce seeds is usually really small, but the seeds in the packet in front of me are as big as mung beans.

He Jun was surprised: "Such a big one?"

Qiu Feng also looked at it curiously: "It's really big."

The researcher responded: "It is convenient to take. It is convenient to plant. After we plant it, we have to cover the vermiculite with a film."

Now He Jun knows.He found that after a certain level, knowledge is interoperable.He smiled: "I went to see the cotton picking before. After the cotton is planted, it must be covered with a layer of plastic film. One is for heat preservation, and the other is also afraid of vermiculite or seeds flying away in space, right?"

The other three looked at He Jun in unison, and were amazed.

Qiu Feng didn't expect: "Did you travel so far to watch the cotton picking?"

And the other two newcomers responded: "Is this show so cruel? I have to learn everything? Is the difficulty the same as we are learning now?"

At this moment, He Jun’s body has already recalled the original hard work before his brain: “... Sigh. Although it is difficult, some things are more physically demanding.” For example, road construction, such as driving a tractor every day.

The working time is far more than eight hours, and he will never accept such a hard variety show next time.Variety shows are not as good as singing and dancing.

The program group is purely doing things, and at this moment, the memory kill is activated, and the painful things of He Jun and his teammates are released.In the scenes with outdated filters, He Jun and Tong Wenle are busy in the fields, He Jun and Guan Zhengyang are working hard to build roads, and He Jun and Ye Hao are experiencing all kinds of tossing and turning equipment during pilot training.

The bullet screens were full of sympathy, and at the same time they did not forget hahaha: "Thinking about it carefully, it is really miserable. This is the first time I see a variety show where I have to participate in road construction."

"I've seen people who participated in road construction. It was the first time I met someone who wanted to participate in road construction for a month."

"Hahaha, it's really miserable. But it also shows that my occupations are actually very hard, just like being an astronaut now. I have to master all kinds of knowledge, and I had to master farming skills (dog head) the day before."

The words were indeed good, but when He Jun faced the sympathetic eyes of the three people around him, the thoughts in his mind changed again and again.

He even thinks that it is really good to do pure research, and there is a unique romance in space research.This romance is similar but not exactly the same as other scientific research projects.

After talking about the mulch, the researcher continued to explain: "Then we will give light. After germination, the seeds must be fixed in the vermiculite, and our first step will be considered a real success."

Qiu Feng knew the process of growing vegetables: "The next step is when the lettuces are about the same size, spread out the lettuce and then water it. Right?"

If someone answers, the teaching atmosphere is very happy.

The researcher Xiao Yingying explained the planting matters very clearly and clearly: "This has a professional ranking and is called thinning. The act of thinning and watering has to go through twice. Otherwise, the lettuce will be crowded together, and it will not be able to grow into a beautiful body. The pieces of this square plate are prepared for the final lettuce. The lettuce after thinning is one grid, and it grows very standard.”

It is very interesting for everyone to imagine.

The researchers are very familiar with high technology, so the female researcher also said: "Of course, many people are very interested in this planting method, so they will choose to buy equipment for planting. Just click on the mobile phone and you can plant. Their planting equipment looks a bit like a shelf. Because it is hydroponics, it is simple and will not make the room full of soil."

Qiu Feng is obedient and honest: "It means that farming is part of human genes. If you have money or not, you want to farm."

Who doesn't want to farm?My mind is full of farming.

Everyone laughed.

The researcher roughly agreed on the process and provided the tools. The next step is to see how the four of them operate.

The lens is divided into four.He Jun in the upper left corner said there: "Give us the same weight and quantity of seeds and the same tools, and we will see who can grow the most lettuce in the end. Our Vacation is so passionate about farming, it would be embarrassing if we lost. "

Qiu Feng said happily: "I prefer to eat lettuce with green leaves. And it tastes better when cooked. Oyster sauce lettuce, garlic lettuce, lettuce soup, and lettuce wonton are all delicious."

Lei San became puzzled: "Speaking of which, didn't we come here to teach people? Why did we turn into growing lettuce? Is this kind of food enough for a meal?"

Zhu Yizheng was even more funny.He was more exaggerated than Qiu Feng, thinking: "If the 30 days have not arrived, I think the lettuce is almost grown, can it be eaten directly? The taste must be tender and crisp. Anyway, it can be eaten raw."

The barrage cracked with laughter: "Only the captain cares about production!"

"Sure enough, apart from farming, Chinese people only care about eating! Food is the eternal god."

"Although I don't like lettuce, I don't know why it's fun to watch them grow. I can't help but want to grow some side vegetables."

"Vacation's variety show will eventually make people want to grow vegetables on the balcony!"

But this time the four of them did not grow vegetables on the balcony, but to simulate space planting, collectively cultivated indoors with lights.In fact, the lighting is not too exaggerated, only the lettuce is illuminated.But every time the lettuce is captured in the whole shot, the picture will be quite ghostly.

He Jun and Zhu Yizheng, who grow ordinary lettuce, started to turn on the white light after the class, and then turned on the red and blue light when they were on.Qiu Feng and Lei San, who grow red leaf lettuce, of course choose blue-violet light, which is really very similar to humans turning on pop-up lights for vegetables in outer space.

Considering that the light that lettuce likes is very unfriendly to the audience, the brightness of the screen was slightly adjusted in the later stage, and the process was sped up, so that the lettuce that had grown for a month could grow rapidly in just 2 minutes.

It seems to be growing lettuce on the earth, but many methods are used in space planting methods.The earth is watered with a watering can, and the group of four uses a syringe.Thinning the seedlings on the earth is basically manual, and the thinning of the four-person team should be carefully handled with tweezers.

After the lettuce in front of them was treated so formally, it seemed that the collective was not normal.In the end, it obviously grew into ordinary green leaf lettuce and red leaf lettuce, but in the hearts of everyone, it was no longer food, but an experimental product.

The green lettuce is as green as anyone has ever seen.The color is cured, the nutritional value is high, and it is rich in various substances and water needed by human beings.

Red lettuce isn't completely red from head to toe.

Its leaves are red, but the bottom is green.The overall tone looks a little dangerous, as if stained red with red pen ink.The water content of this kind of lettuce exceeds that of ordinary lettuce. It is crunchy and can add a lot of water to people.This abundance is the reason why many foreign astronauts prefer to grow red leaf lettuce.

In the barrage, because the green lettuce tastes better or the red lettuce tastes better, it seems like a war between "sweet glutinous rice balls and meat glutinous rice balls" has started.

In the show, the members of the two groups also competed seriously.

"Green looks more delicious. Green leafy vegetables, green leafy vegetables, can they be called vegetables without green leaves?"

"Who said, what happened to our red leaves? It's also stained with green. There is a little red in the green."

"You red look ugly."

"Why are you still attacking with vegetable body?"

"Okay, let's compare the output, don't say much else, compare the output."

The barrage professional burst into laughter because of the "vegetable body attack", and only cared about hahaha.

Planting vegetables is always worth a name, and comparing the nutritional content of vegetables to analyze the value of lettuce.And when the four sets of lettuce were sent for weighing and testing, He Jun and Qiu Feng also explained it professionally.

He Jun's memory has always been considered good among the guests: "We have been growing lettuce during this time, and we have also read a lot of information. In fact, vegetables grown in space are basically not polluted. The biggest difference between them and vegetables on the ground Mainly in terms of variation. The microgravity and other environments of the universe are more likely to cause genetic variation in plants, and the degree of variation exceeds that of normal growth on the earth."

Qiu Feng then explained: "From the perspective of Darwin's theory, any direction of variation is possible. What we can do is to find ways to preserve various mutated traits that are beneficial to human consumption, and stabilize the traits. It can be planted all year round on the earth."

The experimenter in charge of the weighing test cut the lettuce with scissors and put it into a transparent storage bag and sent it for testing.In the end, four test reports appeared on the camera.In addition to the four reports, there is also a report on lettuce experiments grown by real astronauts in space.

In fact, there are many variables between space planting and earth planting, and there are many things to consider in comparison.Fortunately, the show didn't deliberately insist on some people on the earth planting any special effects. It was just to show that space vegetables are not much different from earth lettuce in terms of various nutritional values.

The biggest difference reported on the report is that space vegetables actually weigh more.In He Jun's words, the output is the highest.

Zhu Yizheng's green lettuce was surprisingly the most productive among the four, but his lettuce still couldn't compare to the same variety of space vegetables in terms of weight.

The researcher took four reports and solemnly handed them over to four people: "Everyone has a little lack of planting ability, and the growth rate and yield of lettuce in the end are lower than the lettuce we once planted in space."

In the lower right corner, the program team put He Jun's wild words at that time: "Our Vacation is so keen on farming, it will be embarrassing if we lose."

As a result, He Jun was silent for a while, and when he raised his head again, he was sure: "I'm not sure where else this lettuce has mutated, but it must have mutated in terms of weight!"

Lei San even speculated wildly: "Is it because there is no gravity that you can grow taller if you grow randomly. After all, astronauts will grow taller after staying in space for a month."

As soon as the words came out, the other three looked at Lei San in unison, and couldn't help applauding him: "What a good idea!"

A string of ellipsis popped up over the researcher's head.The difference between vegetable and human species is a bit big.People grow taller, but vegetables mutate!Vegetables can grow upwards normally in space because of phototropism, not because of any strange consequences caused by microgravity.

The correct explanation was added later in the program group: the large size is one of the cases of variation, and the large space vegetables on the market are the result of artificial breeding.

The barrage burst into laughter again after seeing the familiar science popularization in the face of the program group in the later stage.

At this time, the screen of the program showed the scenes of space astronauts planting in space again and again.Some are in capsules and some are on space stations.

They are attentive and focused, floating and seeming to be on the soil of the earth in space.
