Bricks and tiles are in short supply now. Why do I say that? In Huichuan area, bricks and tiles are made by firing clay. The brick and tile kiln in the county town has only been open for a little over two years, and two deep pits have already been dug!

Of course, the ownership of those two huge pits has been transferred to the Lijiapo Brigade.

People now have to queue up if they want to buy bricks and tiles from the kiln without a permit from the kiln manager or other relevant person in charge!

Who knows how long the queue will take? It could be a month or two, or even a year and a half. As for when you can actually buy one, it's hard to say!

Therefore, Guo Daming thought that they could order a batch of bricks and tiles in the name of the brigade. The purchase volume was large, and the price could be negotiated. Then, if any family in the village wanted to build a house, they could come to the brigade to buy them, and the brigade could sell them at the original price.

Of course, cement, roof beams, and sand and gravel can also be purchased in the name of the brigade.

Everyone thought it was a good idea. People aren't broke like they were a couple of years ago anymore. Now, every household has savings that start with hundreds!

Just as the lively discussion was taking place, Li Xiangdong and his group came out.

Liu Changhai, with his sharp eyes, spotted Professor Liu, who wore glasses and looked very refined, and then a young man in his twenties next to him, who also wore thick glasses and carried a military green satchel.

That must be Professor Liu's student, Yu Yang.

Several people eagerly stepped forward to take the bag from Professor Liu's hands, and then helped Li Xiangdong and Li Guoqing carry the large bundles on their backs. Li Jin accompanied Professor Liu to the oxcart, and Liu Changhai secretly asked Li Xiangdong, "What good stuff did you bring back from the south this time? Why is it so heavy!"

Li Xiangdong blinked. "I'll give you a bag of dried oysters and dried red-legged shrimp later."

"Easy to do? What's easy to do?"

......

Professor Liu put his luggage in Li Xiangdong's guest room, ate a few bites of the lunch prepared by Li Lan, and couldn't wait to go and see the 800 acres of saline-alkali land.

"White expanse in spring, torrential rain in summer, nine out of ten years no harvest, half a year's food is bran and vegetables," a local proverb in Huichuan vividly describes the barrenness and infertility of the saline-alkali land.

Standing on the edge of 800 acres of seemingly endless, barren, white saline-alkali land, Professor Liu asked Li Xiangdong, "How did you come up with the idea of ​​using saline-alkali land to raise seafood?"

The people of Lijiapo were used to Li Xiangdong's occasional whimsical ideas and no longer questioned why or how he came up with them.

Professor Liu, however, could not immediately accept that a rural child could have such a wildly imaginative yet innovative way of thinking.

"I think that the high salinity environment of saline-alkali land is similar to that of seawater. If we can utilize the components contained in saline-alkali land itself to create artificial seawater that is similar to seawater, wouldn't that turn waste into treasure and turn saline-alkali land into a treasure trove?"

Li Xiangdong spoke eloquently, “I asked my fourth sister to look up some information before, and I also thought about it myself. The biggest problem with seawater aquaculture in saline-alkali land is seawater. Should we add preparations to make artificial seawater, or should we use microbial reduction methods to turn the saline-alkali components into a modern seawater system that can be recycled for aquaculture?”

"Of course, you will need to decide on either of these methods based on the relevant data during the specific experimental research and development process."

Professor Liu stared at Li Xiangdong for a long time without saying a word. The people behind him looked at Li Xiangdong, then at him, and none of them dared to speak.

After a long pause, Professor Liu asked Li Xiangdong, "Would you like to apply to Pengcheng University?"

Professor Liu works at the Pengcheng Fisheries Research Institute and Pengcheng University. He is also a professor at the School of Life Sciences of Pengcheng University.

He's taken a liking to Li Xiangdong and wants to recruit him.

Li Xiangdong laughed heartily, "I'll try my best!"

Li Xiangdong is 16 years old now, which is not young, but he is only in the third year of junior high school. Professor Liu is particularly sorry that rural education has delayed the development of so many talents!

However, now is not the time to talk about that. Professor Liu quickly returned to the topic of transforming saline-alkali land into seawater.

"There is no precedent in the country for transforming saline water into artificial seawater; it is a long and arduous task!"

"However, once this technology matures, it can be promoted nationwide! There are so many saline-alkali lands in northern my country, and the locals have never eaten seafood. If mariculture in saline-alkali land is successful, it will benefit even more people!"

I believe Professor Liu will quickly grasp the economic value, technological value, and strategic significance to the country.

really.

Professor Liu said, "I need to take some local saline-alkali soil back for testing. As for what happens next, that still needs further research."

Doing research is never a simple matter of talking; it requires a lot of money, manpower, and resources, and may even waste a lot of time and be in vain.

However, before Li Xiangdong died in his previous life, there were already successful breeding experiences in Anxi and Yongliang regions of my country, so this path will not lead to failure.

Some people might worry whether current technology can achieve this, but Li Xiangdong has no such worries at all.

Back when we were dirt poor, we could build an atomic bomb with an abacus, so Li Xiangdong is very confident about the preparation of artificial seawater now.

Actually, Li Xiangdong had other motives for collaborating with Pengcheng Aquatic Research Institute.

This idea, well, the conditions aren't quite right yet. It's just planting a seed, but when the time is right, it will grow into a towering tree.

Li Xiangdong showed Professor Liu the planning diagrams and proposals he had previously created.

"Professor Liu, this 800-mu standardized aquaculture base is planned to be built in three phases. The first phase will be 100 mu, divided into fish ponds and greenhouses, to initially test the breeding of whiteleg shrimp. The next two phases will be 300 mu each, and the third phase will be 400 mu each, with plans to breed several varieties of seafood such as tilapia, grouper, abalone, and Australian lobster."

"I expect that in the next three to five years, the annual production of the Lijiapo standardized aquaculture base will reach 3,000 tons."

Professor Liu took the planning map from his hand, raised an eyebrow, and said, "Artificial seawater hasn't even been successfully developed yet, and you're already planning what to raise?"

Li Xiangdong was even more confident than Professor Liu himself, saying, "Adding trace elements and probiotics to the water to recreate artificial seawater suitable for the growth of different seafood should not be difficult for you!"

Professor Liu smiled confidently, "You little rascal!"

Li Xiangdong didn't need to worry about the rest; a professional team would handle it. All he had to do was provide the money and equipment.
