The 24th solar day.
Mark moved a lot of debris out of the living cabin to free up a fairly large space, and then spread a plastic sheet on the floor and sealed it with plastic sheeting to keep it warm and moisturizing.
Following him, he shoveled a lot of soil from outside and carried it into the living cabin and spread it on the ground.
Rosen saw him and asked him if he needed help, but Mark declined with a smile.
Obviously, Mark does not want to take advantage of others when it comes to growing potatoes. This concerns his face as a botanist, and also involves the dignity of the United States.
In response, Rosen just shrugged his shoulders and did not insist.
Compared with Mark's relatively slow progress, his work progress is much faster.
So far, the glass greenhouse has been built and divided into eight areas, connected to each other but independent, surrounding the container villa like stars over the moon.
This is not only to facilitate Rosen's farming, but also to maximize the benefit of the Oak Wise Man.
The soil in the greenhouse has been turned very soft by poisonous flower vines, and organic fertilizers and various trace elements were mixed under Rosen's command, and Rosen began to sow seeds.
What he grows is not potatoes, but sweet potatoes.
The two are essentially different. The former is a Solanaceae plant and the latter is a Convolvulaceae plant. In addition, the nutritional value and planting methods are also different.
Rosen chose sweet potatoes not just to differentiate himself from Mark, but more importantly because they not only grow much, but are also full of treasures, and are far more cost-effective than growing potatoes.
Of course, the biggest reason is that although he likes to eat shredded potatoes, he doesn’t want to eat potatoes every day.
The only thing that makes sweet potatoes inferior to potatoes may be that the growing season is longer, but for Rosen, who is not short of food, this is not a problem.
In addition to sweet potatoes, Rosen also planted some green vegetables, cabbage, celery, lettuce, peppers, carrots, cucumbers, green peppers, tomatoes... and so on.
Anyway, he bought a lot of seeds and had free land, so naturally he wanted to plant whatever he wanted.
In addition, he also planted some wheat and corn. He has not considered rice yet. After all, it will take a long time to solve the problem of irrigation.
Because they are both busy and rarely see each other, let alone communicate, Mark does not know that Rosen has completed the sowing, otherwise he would be extremely envious.
The 31st Earth Day.
Mark began to cut the potatoes into pieces and bury them in the soil. He also applied fertilizer made from the feces of the six of them.
The process is hard, tiring and quite enjoyable.
But when Mark thought that these potato cubes would grow into potato seedlings in the future, and then bear numerous fruits, all the hard work would be nothing.
He even thought about inviting Rosen over when the potatoes he planted were harvested, so that he could see that his reputation as a botanist was not in vain.
It is inevitable that he always brags about the racial talents of the Chinese people in front of himself.
Is it good to be able to farm?
Can it compare to the burning, killing, looting, trapping, and abduction of cattle that my American ancestors were best at?
With some indescribable emotions, Mark, after planting the last potato, simply scrubbed his body, put on his space suit and walked towards the opposite side.
He wanted to invite Rosen to come and see the potato fields he had cultivated.
Mark was stunned before he even approached the container villa.
Because a glass greenhouse like a crystal palace stood in front of him.
Oh my god! How did the Chinese send up a glass greenhouse? Did they come here not for scientific research, but for interstellar colonization?
Mark was deeply shocked. When he saw Rosen squatting in the greenhouse field without knowing what he was doing through the clean and clear glass, and there was a patch of green seedlings under his feet, he was even more shocked. It's very exciting.
Who would have thought that after working so hard for so long and finally planting potatoes, all the seedlings on Rosen's side would come out.
Is this justified? Is there any science to this?
What plant can grow so fast in an environment like Mars? Mark felt that his knowledge of botany was almost untenable.
Rosen suddenly raised his head at this time, saw Mark, and immediately waved to him to enter the greenhouse.
Of course, entering the greenhouse does not mean opening the door. Instead, you go through a corridor that balances the internal and external air pressure and temperature, and finally enter the greenhouse.
Mark walked all the way and looked at the neat fields and some of the green leaves sprouting from them. Although he didn’t say it, he had to admit in his heart that when it comes to farming, looking at the world, it’s really There is no race that can compare to the Chinese.
"Mark, look, the vegetables I planted before are growing pretty well, right?" Rosen said with a smile: "In a few days, when they grow taller, I will pick some dumplings to make. You must come and taste it."
"Okay." Mark nodded, and then said: "How did you solve the irrigation problem?"
"I know how to do it. Magic, just wave your hand and water will appear." Rosen said truthfully.
But Mark thought he was joking, and thought that it might involve Chinese secret technology, so he couldn't reveal it and could only cover it up with nonsense.
After thinking about this, Mark stopped asking and said: "I am also trying to grow potatoes, and I have thought of how to solve the irrigation problem. I will communicate with you later if I have the results."
p>"Okay." Rosen nodded with a smile and said, "Be safe."
"Got it."
"Go slowly, don't send me off."
The 35th solar day.
Rosen fulfilled his previous promise, pulled out a batch of tender green cabbage (note), made stuffing with pork, made dumplings, and invited Mark to come over and share.
At the same time, he also cooked some home-cooked dishes and opened a bottle of Laobaigan.
Mark was still a little coy when he came, but after he started eating, he slowly let go and kept shouting: "It smells so good! It's so delicious!"
Especially after having a good drink, I was in high spirits, talkative, and talked endlessly. I wanted to sing myself to Rosen.
"You know, the biggest problem in growing potatoes is water. I got 126 square meters of soil. Each cubic meter of soil requires 48 liters of water to plant, so I have to create more water."
When Mark said this, he looked at Rosen and said: "Fortunately, I have thought of a way. I will let you see it tomorrow. How about it? Do you want to come over and witness this historic moment?"
"Okay." Rosen thought of the scene in the plot where it exploded when lit, and said with a smile: "I will definitely go, maybe I can save your life."
" Just kidding, it’s not certain who will save whom." Mark said loudly and boasted to Rosen again before leaving.
The next day.
Mark drove the car and took Rosen under the aircraft. While pushing the pipe connected to a gas tank to the nozzle, he said: "Rosen, let me ask you a question, hydrogen and oxygen What will happen next?”
Note: If you want to know about the relationship between Chinese cabbage and Chinese cabbage, you can research it yourself. In my childhood, I considered Chinese cabbage to be Chinese cabbage.
