Raising flowers and grass?

The speaker has no intention of listening, and Nie Peng looked at the ground outside the bubble tent, and there were several clear shoe prints on the gray dust mixed with stones.

I was suddenly curious, what is the composition of these soils? Otherwise, take it back and analyze it, in case you find any rare substances, it won't be a big profit.

Because these days, the account can only go in and out, and it takes a few days to go out of nearly a million oceans. So while Nie Peng's heart ached, he felt panicked, he was afraid that before his main business was formed, the amount of funds would be broken.

So after thinking of a new source of business, I was inexplicably excited.

"You are really my lucky general" Nie Peng turned around and hugged Jiaying and kissed him fiercely.

。。。。。。

When he returned to the factory the next day, Nie Peng found a few plastic basins, filled them with a few large pots of soil, and after leveling out a few samples for testing, the rest were mixed with water and mud and brought to a corner of the factory.

"What are you doing here?" After a simple cleaning with the tap water of the factory, Jiaying came over humming a little song.

"I want to see if the soil on the moon can grow flowers and grass, and you're done?" Nie Peng's hands were full of mud, and he was dealing with a large cardboard box.

"Well, after washing, how can I help?" Jiaying looked at it and was ready to roll up her sleeves and join in.

"No, no, this is very dirty, don't do it" Nie Peng looked at her small hands with fine skin and tender meat, and hurriedly stopped, "Why don't you go to the market at the door and help me buy a few potatoes, the ones that have sprouted are the best." In addition, buy a tungsten light bulb from the hardware store, about 100 watts, and pull 20 meters of wire. ”

He remembered the movie "The Martian" he watched last year, in which Matt Damon played astronaut Mark Watney, during a human mission to Mars, experienced a bad storm and lost contact with the rest of the team, who thought Mark had died and had to leave Mars in a spacecraft. However, Mark was lucky to survive and became the only human on Mars, but his life supply only lasted 31 days.

In order to survive, Mark not only used his expertise as a botanist, but also used chemistry, physics and other technologies to turn the habitation module into a potato farm, comparable to the Martian version of "Robinson Crusoe". Relying on potatoes for three meals a day, he supported Mars for nearly 500 days, and in 500 days, he realized the connection with the earth.

Compared with the astronaut in the movie, Nie Peng's treatment is not known how many times higher, at least he has no food crisis at present, and he will not be so tragic that he eats potatoes for 500 days in a row. Although he is currently unable to establish a connection between the moon and the earth through technical means, as time progresses, he believes that this day will come sooner or later.

After putting a few pots full of mud into a large cardboard box and fixing them, Jia Ying came back with a bag of potatoes and a bundle of wires. Nie Peng selected a few of the moderately sized potatoes, cut off the sprouted parts with a knife, inserted them in the soil, carefully covered them with soil, and then found a plastic bag to cover each pot to prevent the water from evaporating too quickly.

Jiaying stood aside and watched Nie Peng busy working there, and asked puzzledly: "Can it be planted on such a cold day?" ”

Nie Peng looked at her expression, the corners of his mouth curled, took the wire he bought, and passed through the top of the cardboard box, leaving only a light opening in the box.

"Got it?" Nie Peng asked.

"Do you want to use a lamp to heat it?" Jiaying suddenly realized.

"That's right, potatoes germinate at minus 5-30 degrees Celsius, and they can usually sprout in the freezer compartment of the refrigerator, let alone in this state. I just don't know if these soils can provide enough nutrients. Nie Peng screwed the bulb onto the lamp mouth, found the right hanging length, and buckled the exposed wires outside the carton as a support tenon.

"Plug it in." Nie Peng commanded.

As Jiaying pushed the switch, this simple greenhouse incubator was ready, Nie Peng clapped his hands and stood up, and smiled contentedly.

"If you can really grow it, then it will save a lot of money in the future." He thought hopefully.

"What's the use of planting it? Isn't it just eating? "Jiaying doesn't understand, why do you have to plant it from the moon when you can bring food from the earth?

"Eat? You know how to eat," Nie Peng stretched out his mud-covered hand and grimaced at Jiaying.

"Not everyone can come and go between the earth and the moon as freely as I do, if I don't have this ability, with the current scientific and technological means, how long do you say human beings can survive on the moon?"

"But with the rocket, will you bring the food with you?" Jiaying asked.

"There will always be a day when the food is consumed, and if you can't replenish it effectively, you can only return home. But when you have a source of food, it's easy to do. Nie Peng washed his hands with tap water, and the cold water temperature stimulated his hands to be red.

"Besides, potatoes aren't just for eating. Do you know about plastics? ”

"Nonsense." Jiaying rolled her eyes, who has never seen plastic in this question.

"Potatoes can be made into plastic, starch-based plastics." Nie Peng wiped the water from his hands and explained to Jiaying, who looked incredulous:

"That's what I learned from my professional classes. To put it simply, most of the plastics we use in our daily life are obtained from petroleum refining, also known as petroleum-based plastics. For starch, as long as the intramolecular and intermolecular hydrogen bonds are broken and the crystalline structure of the double helix of starch molecules is disrupted, the melting temperature of starch can be reduced and it can be thermoplastic. That is, the properties of plastics. ”

"So if we grow potatoes, we can synthesize plastic on the moon?" Jiaying somewhat understood what Nie Peng meant.

"No, it's not that simple, starch base has many shortcomings, it's not a real plastic" Nie Peng remembered the starch-based plastic synthesis experiment he did in the school laboratory last year:

"For example, poor mechanical properties and strong water absorption. But as long as it can be grown, then the solution is easy, we can grow sugar cane or cotton, and then use fiber as a reinforcing agent to synthesize a real plastic. ”

"That... How to synthesize? On the moon? Jiaying asked again.

"The synthesis is very simple, a little glycerin, plus a few kinds of equipment in the laboratory can be synthesized, but if you want to mass production, you have to use large equipment. However, if it can really succeed, it will not be far from a real moon base. Looking at the lunar soil in the small bag, Nie Peng decided to take it to test the specific composition first, and see if he could rely on the soil to refine any valuable building materials.
