The Technology Tree of Xueba

The news that Lanhai City took root in the designated sea area made the citizens of Lanhai City very excited. They finally had roots, instead of continuing to drift on the sea.

Many media, represented by CCTV, announced to the world in a live broadcast that China's water city, Lanhai City, was officially established.

In the chat area of ​​the virtual world, netizens from all over the world are discussing the situation in Lanhai City.

Chinese netizen [Qiqiqi]: I am a citizen of Lanhai City, and living in Lanhai City is really comfortable.

The government distributes clothes and daily necessities to us, and we still eat in the big cafeteria of the workplace.

This kind of life is suitable for me, away from the hustle and bustle of the inland, away from the previous circle, I will not be exposed to gambling again.

I, a landlubber, have already learned to swim now.

As long as you get used to life in a floating city, Lanhai City is really a livable city.

Indian netizen [Moib]: I didn't expect Huaxia to actually have a city on the water, this is not a smoke bomb put by Huaxia.

Will Huaxia arrange its floating cities in the waters near our country? That would be too dangerous.

When Huang Ke came to Lanhai City, he didn't just lead the engineers to fix the location of Lanhai City.

They also brought aquatic crops suitable for Lanhai City and fish fry raised in seawater to help Lanhai City establish marine agriculture and animal husbandry.

On December 3, the second day after Lanhai City was fixed, Huang Ke came to the office of Lin Xingkang, the mayor of Lanhai City.

Mayor Lin, we at Xinghuo Technology have prepared the seeds of the plants and the fish fry that Lanhai City needs to raise.

How is Lanhai City's preparations, and whether it can officially start the Lanhai City's agricultural development plan.

Lin Xingkang nodded and said: Lanhai City has already prepared for it. Our city government has already trained relevant talents through the virtual world. They can master the cultivation of aquatic crops and the breeding of pigs and fish.

Everything in Lanhai City is ready, and the core industry of Lanhai City, marine agriculture and animal husbandry, is officially launched.

The amphibious intelligent robot brought equipment and began to enclose a large area of ​​sea around Lanhai City, enclosing an aquatic crop planting area.

Mainly use foam and other materials to build a relatively closed environment on the sea.

This is to prevent pollutants on the sea surface, such as oil spills and plastics floating in the sea, from polluting offshore farmland.

Offshore farmland only occupies the sea surface and will not affect the ecological environment in the ocean.

Instead, they will provide a good living environment for small fish in the sea, just like coral reefs, and establish a new type of marine ecosystem with offshore farmland as the core.

Citizens of Lanhai City carried grid-shaped rectangular seed trays and placed them on the sea.

The artificial seeds in the seed tray will germinate within 2 days under the sunlight and suitable temperature.

After three days of growth, the seedlings can be transplanted into the planting boxes for aquatic crops.

The planting boxes for each aquatic crop are different. The planting boxes for rice are larger seed trays. Part of the planting boxes for cucumbers is submerged in the water, and there are pillars for cucumber vines to climb.

In December, the water temperature in the Bohai Sea is already very cold. This season is only suitable for planting potatoes and cabbage.

These two genetically modified aquatic crops have enhanced their tolerance to severe cold.

Huang Ke watched the citizens of Lanhai City diligently sowing tens of thousands of hectares of sea area.

Even if the offshore farmland is mechanically assisted, people are still needed to check the planting situation.

Agriculture and animal husbandry are relatively tiring occupations in any era.

Huang Ke said with emotion: Potatoes and cabbage can only be harvested for one month, and the re-sowing will have to wait until the Bohai sea temperature warms up in March next year.

Here in the Bohai Sea, only in January and February when the water temperature is extremely cold, it is impossible to grow aquatic crops.

Mayor Lin Xingkang said: Agriculture is easier to take care of, let's take a look at the pig and fish farming industry.

It is impossible for people to eat only vegetables, and they still need to consume enough protein to survive in the sea.

After years of crazy fishing in the coastal waters of Huaxia, even people who are always motivated by profit use nets to fish, and there are no small fish fry in the fishing grounds. How can sustainable development be possible. We also have to rely on our own farmed fish for protein.

Huang Ke and Lin Xingkang walked towards the fish farm on the other side of Lanhai City.

The workers and amphibious intelligent robots here are laying huge fishing nets in thousands of hectares of sea area.

The openings of the fishing nets are the size of a fist, allowing small fish to pass through smoothly.

Lin Xingkang looked at the pigfish placed in the huge water tank on the edge of Lanhai City. The fry of the pigfish were about the size of a fist, and it just couldn't swim out of the fishing net.

Pig fish has a round head, it has no fins, only a tail, and its gills are relatively small.

Pigfish is a small fish that looks chubby, and its appearance is very cute.

Such a big pig fish can be eaten directly, so how can it be used for breeding? Lin Xingkang asked in surprise.

Huang Ke introduced: This is the fry of pigfish, how can it be eaten? When it is fully mature, it can grow to the size of a killer whale and become a monster weighing several tons.

Pigfish is a creature we found in the ocean. It could only live in the deep sea, and its size has always remained so large.

We collect all kinds of marine fish and genetically modify them. Only the native fish genes of pigfish are convenient for us to modify.

After the size of the pigfish is enlarged, it will not affect his life, but it will become lazier and lose the ability to prey on itself.

For a farmed fish, this is not its shortcoming at all.

The citizens of Lanhai City quickly set up a breeding space for pigs and fish.

Put down the water tank with pig fry in the fishing box, open the water tank after putting it into the sea, and directly aim the pig fish in the sea water.

The pig fish hesitated for a moment just entering the sea water, and they slowly swam around.

Tens of thousands of pigfish were thrown into the ocean, and they swam in the water for a while, floating motionless in the water.

Lin Xingkang saw the condition of the pigfish, and he asked worriedly: These pigfish have been transported for a long time, do they suffer from some disease? Why are they not moving?

Huang Ke introduced with a smile: The name of this fish is pigfish because of its extremely lazy character. Except for eating and mating, they are too lazy to move in other situations.

At this moment, a small boat entered the pig and fish farm, and it continuously sprayed feed into the farm with a pipe.

After the pigfish smelled the scent of the food, they immediately started to swim over, scrambling to devour the food.

Mayor Lin, don't you see that they are active now, pigfish are omnivorous animals, they will eat the roots and fruits of plants and some small fish and shrimps.

The feed we are feeding now is straw mixed with bean cakes and some small dried fish.

You can adjust measures to local conditions, use the straw of aquatic crops and the internal organs of marine fish to dry, and then mix and feed them to pigs and fish.

But don't feed the pig fish's internal organs, it will make the pig fish taste sour and difficult to swallow.

Huang Ke watched the marine agriculture and animal husbandry in Lanhai City go through their construction, and began to take the most basic form.

It only takes another month to know whether the marine agriculture and animal husbandry designed by many experts from Xinghuo Technology can meet the basic requirements.

This is related to whether the water city can achieve true self-circulation. It is unrealistic for a water city hanging overseas to rely on local blood transfusion for a long time.
