[Barrage: Anchor, do you have enough......]

was once again swiped by the word, and Chen Mulin also fell silent for a while.

Yes, it is enough to grow a small area of potatoes, but now it is 1,800 square meters.

If the soil does not have enough nutrients, although the seeds can still sprout on their own, it is difficult for them to survive, and even if they are lucky enough to survive, they are unlikely to bear fruit.

For example, it takes three years for a fruit tree to grow from cultivation to fruit, and if it does not have enough nutrients, let alone fruiting, it is even a question of whether it can grow up.

I remember when I was a child in the countryside, the kernels that were thrown away from eating fruits sprouted on the side of the road, because no one watered them, there were not enough nutrients, and after a few years, they grew from the original ten centimeters to dozens of centimeters high.

[Barrage: I suggest that the anchor go to the Martian to borrow some. 】

[Barrage: The legendary Martian has come out to play soy sauce again. 】

[Barrage: Looking for Martians. 】

[Barrage: Recommend an up-and-down laxative pill to ensure that the anchor ...... in a very short period of time]

……

"I believe you ghosts!"

Chen Mulin complained: "I still vomit and vomit laxative pills, even if it really works, it is for nothing, I eat so much, except for the part that is absorbed, there are still so many things that are pulled out, and the nutrients will not increase out of thin air." ”

"Also, the Martian hasn't even seen a shadow now, how can I borrow it?"

"Besides, Martians don't know if they poop or not!"

"Even if a Martian, can you guarantee that his is not poisonous? You must know that even the chickens they eat are poisonous, and I don't want to be poisoned by the "green food" I grow!"

[Barrage: Then the anchor, what are you going to do?]

[Barrage: Do you want to ask for support from the earth? My manure pit is almost full, as long as the National Space Administration agrees, I will immediately call a car to send it over. 】

"The brother who wants to send, I thank you for your kindness, even if the country agrees, it will take almost a year to be transported to Mars, you still save freight, and keep it for your own vegetable field!"

Now Chen Mulin is very distressed, and he has made thousands of calculations, but he has only missed this problem.

I'm still thinking about how much to plant at once, but now it seems that I can only plant a part of it first.

Chen Mulin said: "It seems that this is the only way to do it now, first plant the first layer, and then plant the top two layers when the land is fertile, it shouldn't take too much time." ”

There is also a large amount of XX element in the soil, which is also part of the nutrients required by plants and the human body.

Chen Mulin's current plan is like this, first plant some beans, potatoes have a short growth period, can be planted in large quantities, it will not absorb the nutrients in the land at one time, in addition to the elements in the land, after harvesting potatoes, potato seedlings can be chopped as fertilizer, repeated several times, the land will have enough nutrients. (The author doesn't care too much about Bibi, and he doesn't know if it's right.) ）

Then, Chen Mulin took the sailors to visit other equipment.

Time passed quickly, and after an hour, the farm was completed on schedule.

Chen Mulin returned outside and said solemnly: "Brothers, the farm has been completed as scheduled, and next, although I am very confident, according to the rules, I must conduct a test, and I can only put it into use normally after the test is passed." ”

Then, Chen Mulin raised his left hand and clicked a few times on the tablet on his wrist to turn on the farm's system and start supplying oxygen, heating, etc.

As the progress bar fills up, four large words "Pressure Stability" are displayed on the screen.

Chen Mulin raised his hand and showed it to the water friends by the camera: "Brothers, your worries are unnecessary, there is no air leakage on the farm!"

"Next, it's time to test the operation of the farm system!"

After speaking, Chen Mulin pressed the tablet a few times again, and as the progress bar was full, the farm's systems were all activated instantly.

The flat panel shows that oxygen from the base is being supplied to the farm, and fresh water is also flowing through pipes to the base, into the equipment, and then begins to sprinkle water.

The purpose of this is to test whether the farm can withstand changes in diversity.

After a series of operations, the indicators of the farm have been displayed normally.

This is also expected by Chen Mulin, after all, it is a 3D printed thing, and the probability of error is not high, even if there is an error, the error will be very small, so small that it can be ignored.

Although I was confident, I still had to go on with the test.

With the current test, the stress test on the farm is fully compliant, and a series of indicators are normal, and now there is one last test, which is to enter the farm in person during the normal operation of the farm.

Similar to the structure of the base, there is a constant pressure cabin at the entrances and exits, which is necessary, and Chen Mulin also set up a backup for insurance, which is also the same as the base.

"Brothers, this is the last test, if it can pass the test, the farm can basically be declared operational!"

Why is it said to be basic, but directly put into use?

Because the test can't be so perfunctory, after all, it's just been tested for a short time, and a series of tests have been completed, and it needs to be maintained to see if the farm can withstand it after a long time of operation.

"So, I'm going in!"

After speaking, Chen Mulin walked over, opened the hatch of the constant pressure cabin and walked in, then pressed a button, waiting for the air pressure to maintain balance with the air pressure in the farm.

"Ding...... The pressure is stable!"

As the prompt sounded, Chen Mulin calmly opened the hatch.

However, at this time, an accident appeared, and the constant pressure chamber made a strange sound.

With a muffled "bang", Chen Mulin's feet were unstable, and he was blown out along with the constant ballast cabin.
