Agriculture Idol

Chapter 68

After completing the first agricultural live broadcast in the past six months, Li Chengxin checked the data in the system.

Although there are still nearly 10 viewers, the contribution value is still not enough!Let's do it and work hard!

After returning to Hongming Village, Li Chengxin planned to start cleaning up the sea area in front of the houseboat that the village circled for him.

The first thing to do is to clean up the garbage on the beach and in the sea. Hongming Village has always had special employees to regularly clean up the garbage that floats to the shore of the village, but usually it is only plastic bags and foam balls that fishermen use to locate in the sea. of.

Li Chengxin also occasionally thinks of going to the rocky beach to dig through the garbage, and every time he picks up garbage in the live broadcast, the coconut that looks like a biochemical weapon will be dragged out by the netizens to whip the corpse, and he always hopes that Li Chengxin will pick up another one.

What kind of owner will have what kind of dog. It started with holding sticks on the rocky beach when I was a child, and now the melon skin can pile thick wooden boards next to my small nest.

In fact, even if someone cleans up the coast all the time, there will still be a lot of degradable but non-degradable garbage on all the coasts and shoals in the world, such as wood, metal, and even the remains of fish bones and shells.

The accumulation of these non-degradable garbage on the seabed will prevent the sediment below from accessing oxygen, slow down the oxidative decomposition rate of degradable garbage, and cause the sediment to deteriorate.Therefore, cleaning up other biodegradable garbage is also an important step in cleaning up the marine environment.

Zhou Hao's resort construction consultant team also knew this. The construction team they hired even used machinery to turn over the seabed near his resort without damaging the reefs and coral reefs as much as possible. In this way, the subsurface Garbage can also accelerate oxidative decomposition.

According to the villagers who saw the scene, the sunless sea mud was basically rising up a few kilometers away. Many fishing boats were waiting nearby and caught a lot of fish in the sea mud.

Of course, Zhou Hao, who was in charge, also asked the coast guard and staff to supervise the work on those fishing boats, picked out juvenile fish and rare and endangered fish that were not suitable for commercial use, and either released them or sent them to resorts to raise them.

Fortunately, the area of ​​Li Chengxin's "experimental field" is not large. He is alone, occasionally with the help of Brother Xiaoyong and Zhou Hao. Sometimes he finds a few workers on shifts from Zhou Hao's construction site, and it takes about two days to complete the experiment. The deposited garbage was picked up, and then it took another day to slightly turn over the seabed near the shallow sea with a rake to ventilate the sand below with oxygen.

Then, Li Chengxin spent a few more days confirming the position of the tidal flat (referring to the tidal flooding zone between the high tide level and the low tide level of the coastal spring), mastered the shape of the seabed of his "experimental field", and mapped out the future "prospect" "The picture scroll.

"Xin Wa'er, what is this?" Brother Xiaoyong asked, pointing to a blue oval drawn by Li Chengxin with a crayon.

"Fish." Li Chengxin said in a bad tone. After all, he was asked a lot of questions by Xiao Yong because of his poor painting skills.

Brother Xiaoyong also knew that Li Chengxin was bothering him, so he pointed to the edge of the foreground picture and said, "The last question is really the last one."

"Let go!" Li Chengxin simplified the phrase "let go of your fart".

"What is this stone-like thing?" Brother Xiaoyong pointed to a rough long object drawn with black crayon on the edge.

Li Chengxin covered his face: "That's a biological water purifier!"

Brother Xiao Yong obviously didn't know what a biological water purifier was, but he had already agreed to the last question. In order to keep his promise, he kept winking at Zhou Hao, saying to the effect of "you asked."

Of course, this wink was faithfully conveyed to the netizens in the live broadcast room, and the netizens who were one step ahead of Zhou Hao to appreciate the glint of this look also booed one after another.

【What biological water purifier is the same? 】

[Xin Wa'er, explain to me quickly? 】

【Solve! 】

Li Chengxin has always been magnanimous to the netizens who provided him with contribution and reputation, so he began to explain to them.

"The biological water purifier I want to use is actually mussels, also called mussels or mussels. Mussels are mussels in English. Mussels are a kind of shellfish with high environmental requirements. In theory, an adult Mussels can filter and purify more than four liters of seawater per hour.

"For raising green-mouthed clams, you should usually choose an outer sea area with fresh water quality and smooth water flow. However, if you raise green-mouthed clams in an inner bay-type sea area where water flow exchange is poor, feed is relatively scarce, and the water quality is easily polluted, green-mouthed clams can help clean the sea. The water in that area.”

After some explanation, Li Chengxin also searched the Internet for pictures of green clam cultivation.Below the sea surface, strings of green-mouthed mussels hang down in the sea. They look quite like the ones in Li Chengxin's paintings.

He and Brother Xiaoyong and netizens explained the things on the painting one after another, and Li Chengxin planned to start the first step - building a beach.

Since the waters near Hongming Village are mostly stone beaches, there are few bivalve shellfish, and the type and quantity of bivalves that like to hide in the sand are a major indicator of the offshore marine environment.

Therefore, the beach Li Chengxin wants to build is not the artificial beach at Zhou Hao Resort, but a beach used for experiments and biostatistics.

But thanks to Zhou Hao, at least he doesn't need to buy sea sand from faraway places.

The sand used for beaches is different from the sand used for construction. It needs to be mixed with sand of various particle sizes such as gravel sand and fine silt, so as to create an environment where various organisms can survive.

Li Chengxin, with the help of Brother Xiaoyong, built a 10m x 10m sandbox at the end of the tidal flat.The edge of the sandbox is at one meter from the waterline at low tide, so that the beach borders the ocean, and due to the existence of the sandbox, the seawater cannot take away the sand in the sandbox.

Zhou Hao asked the sand transport boat to transport the sand to the sea area as close as possible to the houseboat, and then several workers rowed a few small sampans borrowed temporarily to transport the sand to the shore.

When the tide is high, it is much more convenient to transport the sand. The workers only need to row the small sampan above the sandbox and pour the sand into the sea.When the tide falls, it is necessary to manually drag the sand sled for a certain distance, and then shovel the sand in the sand sled into the sandbox.

As for leveling the sandbox, no manpower is needed, Tidewater will take care of it all.

After the low tide that day, Li Chengxin and Zhou Hao walked on the seabed, which they couldn't usually see. They planned to see what other creatures there were besides sea urchins and a few shellfish.

Through the periscope before, netizens have seen the white and barren seabed under the ravages of sea urchins. The exploration after the ebb tide gave them a more intuitive impression. There is a thin layer of oyster shells on the seabed, all because of the lack of Oysters dying for food.

Li Chengxin and Zhou Hao walked by, stomping heavily.

A few sea urchins that slipped through the net were picked up by Li Chengxin into the bucket in his hand, and then they were taken to Uncle Donghai and thrown into his sea urchin breeding cage.

Until the tide began to rise, apart from a few skinny clams and a few barnacles, the two found only a thumb-long square-head crab crawling alone among the empty shells.

Li Chengxin looked at the sea and saw that under the very beautiful and clear blue sea, it was actually very empty.His childhood memories of searching for salamanders and oysters among the kelp that rose to the surface were all gone.

　I have never had a good impression of big cities made of steel and concrete. The most comfortable memories are basically my grandma’s house in the country and the small seaside town where I am now... But I will leave here in a few months to seek a living in a big city...
