Speaking of which, silt dams have a history of hundreds of years on the Loess Plateau.

Mr. Li Yizhi, a pioneer of modern water conservancy and a beneficiary of the entire Sanqin land, also regarded the silt dam as part of the strategy for the management of the Yellow River.

The specific method of silt dam is very simple - barrage and ditch damming.

The rivers of the Loess Plateau have a high sediment content, and after being blocked, in just a few years, a good river will be formed.

Of course, it is easy to say, but the specific site selection and construction is not so simple.

It's not that Wang Manyin and the three of them can do things well by sitting in the soil and chatting and smoking a few cigarettes, especially when it comes to digging ponds and raising fish, and they have to be thoughtful.

Although the Loess Plateau is arid and rainless, except in summer. Torrential rains often occur, forming flash floods and landslides. If it is not planned scientifically, a rainstorm may make the people of Jar Village busy in vain.

Just like a certain village party secretary, the apple trees planted in the village do not bear fruit for several years, and he specially invited a technician to give guidance.

After seeing the fruit trees, people told them that the trees were plump and needed to be pruned.

As a result, the village party secretary scolded the technician for messing around, "cutting people's hearts", and then blew the other party away.

Therefore, Wang Manyin deliberately talked about the difficulties of the silt dam in front.

The best way is to let professionals do professional things.

"Man Yin, you're right, this is really not a decision that can be made by patting your head, we really need to ask someone who knows how to guide you."

After listening, Wang Lianshun nodded vigorously.

"Another question, what kind of fish do we raise and where do the fry come from?" At this time, Liu Xiangyang interjected.

Wang Lianshun was confused when he heard this, and asked incomprehensibly: "What kind of fish can you raise, can't you catch some fry in the river?" ”

"Captain, there are many kinds of freshwater fish. Some individuals do not grow very much, and some grow very slowly. Liu Xiangyang explained, and then asked, "Right, Brother Wang?" ”

Naturally, he has seen many kinds of freshwater fish and eaten them many times. However, since I was a child, I have lived in the city, and my knowledge of fish has surfaced.

How big can all kinds of fish grow, but it is not clear, so they can only tentatively ask Wang Manyin for help.

Of course, in his heart, he didn't think the other party knew.

Wang Manyin was not stunned.

Although he had never actually raised fish, he had lived in the countryside for more than ten years before crossing and had seen people digging fish ponds.

In addition, after graduating from university, Wang Manyin joined the work, but his girlfriend was not found, but he evolved into a senior fisherman, and he knew all kinds of fish knowledge well. So I was not stumped by Liu Xiangyang's question.

"That's right, it's remarkable that ordinary crucian carp can grow half a catty a year. Like carp, grass carp, herring carp, silver carp, these can grow a few catties if they are fed well in a year. ”

As he spoke, Wang Xingxing deliberately gestured the length of the fish body with his hand.

If it weren't for the fear of being too shocking, he even planned to tell the two about fishing methods for various freshwater fish.

"What do you say, you must feed the big fish. Feed a thousand, each of our second team can share dozens of catties of fish, and the New Year will be beautiful. ”

After listening to Wang Manyin's narration, Wang Lianshun's eyes radiated brilliance.

The blood was boiling for a while, and I couldn't wait to call the members to work immediately.

"Dozens of pounds? Uncle Lian Shun, do you really dare to think, where does the fish feed come from? Wang Manyin asked speechlessly.

"Still want to be fed? I didn't feed the fish in the Dongla River, don't you still live well? ”

"It's wild fish, and a few are okay. Can pigs grow fat by feeding sweet potato seedlings? Wang Manyin's words made the other party completely dumbfounded.

After a pause, he said: "If you consider it from the perspective of saving, our can village is the most suitable for raising grass carp." Not only does it grow fast, but it's also easy to feed. Other fish need to be fed, and grass carp can grow by eating aquatic plants alone, but they grow more slowly. ”

"Then let's feed grass carp......"

It was almost noon before the three of them discussed the basic things.

On the way home, Wang Manyin deliberately reviewed the conversation process. After confirming that the convocation didn't say anything out of the ordinary, he calmed down.

During this period, Wang Lianshun also invited him to report to the village together, but Wang Manyin simply refused.

The reason is very simple, I am not a village cadre, so I will not join in the fun.

Fish farming looks like a good thing, and theoretically there will be no turmoil. But...... In these years, who can say clearly. I don't want to be set up as a model, so I'll leave the matter of showing my face to others.

Just keep going, just wait for 10 years.

After dinner in the evening, Wang Lianshun took Liu Xiangyang with him in a hurry, and directly found Wang Manchu and Zhao Jianhai to report. He did not mention building a dam to raise fish at all, but only said that the second team planned to find a ditch and silt dam by the Dongla River to contribute to the increase in grain production and harvest.

These words were very much in line with Zhao Jianhai's thoughts, and he slapped his thighs when he heard it, and even praised Wang Lianshun for his high consciousness.

Some time ago, he had just finished holding a pig mobilization meeting for the second team, but he was beaten at night. Although the murderer was not found, it was confusing.

But Zhao Jianhai has always remembered it in his heart, and he also has opinions about Wang Lianshun.

Let him change his opinion today, this person is still conscious.

Zhao Jianhai was excited, and put forward his own opinion: "I fully support this matter, but your steps are still a little small, you should take a long-term view, dare to think and dare to do!" ”

According to his rhetoric, only making an earthen dam in the fork of the ditch does not show the ability of the members of our jar village.

The Dongla River should be cut off directly and a larger earthen dam should be built along the two hills at the head of the village. Even if you can't be the first in the original West County, you must strive to be the largest in the Shibi Festival.

At that time, the entire Dongla River will become a flat river, which can add thousands of acres of fertile land to the village of Jars......

After listening to Zhao Jianhai, Wang Lianshun was almost stupid.

I'm a good girl! He originally thought that he dared to think, who knew that the pattern was too small.

If you only build an earthen dam on the river to intercept the flow during the dry season, it will not take much effort.

However, if the entire Dongla River is to be intercepted and the silt dam is to block the two mountain passes, the amount of work will be large, at least a few tens of meters high...... Is this something that can be said as soon as the lips are closed?

The men, women and children of the jar village may not be able to complete it after several years of busyness.

They all go to build barrages, who will plant the fields?

How did Director Zhao come up with such a nonsense idea?

Not to mention him, even Wang Manchu was frightened, and hurriedly said: "Director Zhao, your idea is very good. But if we stop all the Dongla River, what should we do if there is a drought and watering in a few villages downstream? When the time comes, if the fight for water causes conflicts, it will kill people! ”

"Yes, fight for water, I almost forgot about this stubble!" Wang Lianshun's face also changed greatly.

The Loess Plateau is short of water, and people naturally pay more attention to the flow of water.

There are more than 10 villages in the upper and lower reaches of the Dongla River, large and small, because there are too many conflicts over water during the drought season.

Wang Manchu and Wang Lianshun have both experienced it.

Every time there is a fight for water, the whole village of men, women and children go into battle, each holding a stick and a shovel...... The two sides began to reason first, and if they couldn't make sense, they started fighting, and many people were beaten to the head and bleed. There are even those who use guns, causing deaths.

The trouble was so big that even the people of the Shibijie Commune couldn't solve it, and in the end, someone from the county solved it.

In some places, the method of drilling fire urns is adopted for water competition: each side makes a large urn, cuts off the bottom of the urn, lays it flat on the stone platform, and sets up a fire to roast.

Until the big urn burns red, each villager will be selected to compete in a giant drill fire urn. The one who comes out first wins, and the village can give priority to irrigating the crops.

"That'...... Forget it, first according to what the second captain said, let's silt a small earthen dam. Hearing Wang Manchu talk about the history of the water struggle, Zhao Jianhai immediately began to retreat.

I want to do something eye-catching, but if it causes a large-scale fight between the two villages, a good thing will also become a bad thing.

As the initiator, I am afraid he will not be able to get rid of it.

Hearing this, several people breathed a sigh of relief.

Liu Xiangyang felt that he understood why Wang Manyin was reluctant to come over to report.
