Due to the good water conservancy conditions, Mae Chi Town introduced a new aquaculture project - pearl farming as early as a few years ago. As a result, pearl farming began to make some progress, and a pearl market was opened in Mae Chi Town.

If a distinguished guest is coming, it is inevitable to give them a few strings of pearl necklaces, which look noble and elegant when worn around the neck!

Two female professors came to the store this time, they were responsible for developing new projects, Han Sanjiang felt that they had finally come to the store once, and every time they came, they would bring benefits to the store, so they couldn't let them go back empty-handed, so he asked Mu Chunfeng: "Old Mu, you said that these professors came to our store, and they finally came once, we can't let them go back empty-handed, right?

Mu Chunfeng replied with a smile: "Let's give each of us a pearl necklace! This looks not only elegant, but also very fashionable, this one wears gold and silver, some of them are too popular, I think we will take them to the pearl market to play, walk around, let them open their eyes, and by the way, learn about our Zhuji's special products! Doesn't this make them happy and happy?"

Han Sanjiang said: "In two days, Professor Gao Yue'e and Professor Luo Xinfang will leave with two interns, and we have to give them a gift they like before they leave!"

Mu Chunfeng said: "To be honest, I also like pearls, yellow pearls, silver pearls, black pearls, they are all good treasures that I can't put down! It's because pearls are a bit expensive, and I am reluctant to buy them! If we give them away, it is indeed the best choice! Otherwise, tomorrow we will accompany them to the Meichi pearl market for a walk! Let them be happy, maybe it will bring us unexpected gains." ”

"Okay then, we'll take them to the pearl market tomorrow!" Han Sanjiang replied happily.

The next day, Han Sanjiang, Mu Chunfeng, and Jiang Yuanqiao accompanied Professor Gao Yue'e and Professor Luo Xinfang, as well as two of their female students, to the pearl market in Meichi Town.

Professor Gao Yue'e, who was sitting in the car, saw that the road to Meichi Town was full of large ponds, and there were rows of plastic mineral water bottles in the ponds, neatly arranged on the water surface, which seemed to be tied to those wooden stakes with threads, and the water was clear, and occasionally a few small fish jumped out of the water in the pool, so she couldn't help but ask Han Sanjiang: "Secretary Han, what is raised in this big pond?" It's like there's a line in the water, and those empty bottles of mineral water are like buoys in the sea, and I know that the sea is pulling the line like this, with foam buoys on it, and there's a line in the water, and there's kelp hanging under the line, and they're farming artificial kelp! What are you farming?

Han Sanjiang smiled and replied, "We are cultivating pearls here!"

"Pearl?" Gao Yue'e and Luo Xinfang couldn't help but ask.

"Yes, it's a pearl!" Mu Chunfeng nodded back.

"How do you raise pearls?" Gao Yue'e and Luo Xinfang asked in surprise.

Mu Chunfeng did his homework on pearl farming yesterday, pointed to those big ponds with water and said: "Professor Gao, Professor Luo, then I will popularize it for you, let's look at this large pond, the pond is pulled in a straight line, every meter or so will pull up a row of lines, every three meters or so on the line is placed a plastic empty mineral water bottle as a buoy, every zhang or so there is a wooden stake exposed to the water, it is the pillar of the line, the line is tied to the stake, the water level remains submerged line. There is a river mussel hanging under the line, the river mussel is put in the pearl factor, the pearl is raised from the river mussel, every time it is time to collect the pearl, the river mussel opens the shell, takes out a lot of pearls from it, and then strings the pearls into a necklace, processed into high-end jewelry, some pearls are not in good shape, and they are not good-looking, they are crushed into pearl powder, used for beauty! ”

"Ah, pearls are raised in river mussels, and today we only found out, Mayor Mu, if you don't say it, we don't know yet!

Mu Chunfeng continued to explain: "This pearl farming, compared to fish and shrimp, is much better, the first pearl does not need to be served like a fish, every day cut grass and sprinkle feed for them to eat, in this way, pearls as long as the good water, and prevent the mussel from disease, the rest to nothing? ordinary river mussels are difficult to raise pearls, generally choose to raise pearl mussels or spinnaker mussels. Two years of nucleus, three years of planting, five years of mussels, generally 80 to 120 spinnaker mussel shells to breed seedless pearls about 500 grams. The general method of aquaculture, to single hanging method of breeding as well, the water environment of mussels requires sunny ventilation, water depth of more than one meter, no aquatic plants, weak flowing water, water neutral, to prevent toxic sewage from entering the culture pearl waters. The mussels are raised in the most abundant food water layer, the breeding area of the pond should be adapted to local conditions, the small one is three to five acres, the large one ranges from more than ten acres to dozens of acres, the water quality is generally more fertile, the bait is rich in organisms, and the pond can also be polycultured fish, such as grass carp, bream, crucian carp, etc., but it is not suitable to stock the competitive fish, such as: silver carp, screw green, mullet, catfish and some other ferocious fish that eat small fish and shrimp. ”

"It turns out that there is so much knowledge about pearl farming? You Zhuji people all like to do different things, you make hardware at the entrance of the store, you raise pearls in Meichi, you grow strawberries in Shanxia Lake! Grass tower grows medicinal herbs, Datang makes socks, Shaoxing makes textiles, and Fengqiao makes shirts! May Day makes aluminum! This is very interesting!" Professor Gao Yue'e sighed.

Han Sanjiang replied with a smile: "That's what we Zhuji people love to toss, so we have created so many industries!"

"Hehe, don't toss, there's nothing? In short, you Zhuji people, let me admire! It is really amazing to be able to make these achievements in such a short period of time! If I, Gao Yue'e, am from the store, I am proud?" Professor Gao Yue'e replied with a smile.

"Professor Gao, you are actually already a part of our store, you have continuously developed new products for our store, and have made indelible contributions to our store, if you want to be a storekeeper, we are ready to welcome you with both hands!

"What's wrong with the small place? The small place has also leveraged the big economy, and your store is no worse than anywhere else! You can join forces with our four famous universities, Peking University, Tsinghua University, Nankai University, and Fudan University, and your strength should not be underestimated! Who dares to compete with you!" Professor Gao Yue'e was angry when she remembered those things that refused their cooperation.

"I hope Professor Gao is right, with the full support of your four famous universities in the future, we will definitely soar to the sky!"

Professor Luo Xinfang was more concerned about pearl farming, so he asked about pearl farming: "Mayor Mu, what links do you need to pay special attention to in this pearl farming?

Mu Chunfeng had to patiently explain: "To raise pearl mussels, you should choose a pollution-free river, with sufficient oxygen, fresh water quality, flowing water, and sufficient material exchange, which is suitable for the environment for the growth of pearl mussels." Pearl mussels are generally raised from 800 to 1,200 per mu and 600 to 800 on the outer eaves. When cultivating pearl mussels, remember not to breed in still water, once encountering high temperature, shallow water, low pressure, it will cause hypoxic death, so the water flow must be kept smooth, keep the water fresh and oxygen sufficient, if the long-term hypoxia situation, even if the pearl mussel does not die, but the pearl will be produced slowly! Polyconstriction worms, etc.), affecting the production of pearl mussels, so it is necessary to do regular cleaning, generally in April and October, brushing every other month. After doing this, I was able to raise pearls without any problems!"
