Lu Changhua ran back to the duty room, and when he counted it, there were seven barrels.

"Hurry up, Squint and fill the bucket with water."

"Da Hong Erhong took a shovel and dug a pit with me."

"Dagui, you go to Zhao Laosi, transport some bricks and cement, and make a pool."

The crowd was busy.

The task of feeding the fish was handed over to the two little daughters-in-law.

"Where are you digging a hole?"

Da Hong ran with a shovel.

"On the edge of the ditch on the south side."

The three of them ran to the side of the ditch and dug it.

Soon a small pond 40 centimeters deep and 5 meters long and five meters wide was dug.

"Bring the water in."

And a stream of water drew from the ditch next to it.

Soon the water was full.

"Plug the inlet and bring all the fish."

Lu Changhua added some spring water to the bucket in a small basin to let them get used to it.

At this time, at noon, the sun is high.

The water temperature of the newly dug little pond soon increased.

"Pour it in, pour it slowly."

The three of them put the bucket into the small pool and tilted the mouth of the bucket into the water.

The koi fish in these barrels swam around the mouth of the barrel for a while, and then swam smoothly into the pool.

Soon, the small pond of 25 square meters was covered with a layer of colorful small koi.

That's called a good look!

Da Hong and Erhong looked stupid.

Squint also ran over with a shovel.

When I saw a pond full of koi fish, I couldn't speak with my mouth open.

"Looks like we have to let Master Lin's bulldozer go out!"

"Squint, you're here to watch."

"Put water once every two hours, then fill it up again, and dig with a shovel at both ends. Do you understand? ”

"Yes, I can do it."

"The amount of water discharged and the amount of water entering should be small to prevent the water temperature from changing drastically."

"Yes."

Squinted looked at his watch, his small eyes narrowed into a slit.

At this time, Hu Dagui came back on a motorcycle.

"Changhua, Zhao Laosi has been notified."

"Okay, you go to the maintenance team again, let Master Lin hang up the bulldozer shovel, and push a pit for us."

"Okay."

Hu Dagui turned around and went again.

Lu Changhua took Da Hong and Erhong to dig on the edge of the pool.

Dig out a small pool of twenty-five square meters again.

Then dig through the two pools.

"Squint and let the water in."

Koi fish swim around in this small pond of 50 square meters.

"Bring fish food."

They were busy feeding the fish, and Zhao Laosi came with a carriage.

There were bags of cement and tools pulled on the car.

"Master Zhao, that's not enough."

"I heard Dagui say that you want to make a fish pond?"

"Yes."

"Half underground, half above ground."

"Find someone, I'm going to make a big pool."

"Then Lao Lu has to go to the brick factory to pull bricks."

"No problem."

As he spoke, the roar of the tractor rang out.

Master Lin is here.

Lu Changhua beckoned to him.

Master Lin came in with a tractor detour and bulldozed the earth on the south side of the ditch.

Soon a large pit of nearly five hundred square meters was launched.

Hu Dagui went to find Lao Lu again, and took Dahong Erhong and Squint Eye to follow the car to the brick factory.

Five carts of bricks were pulled in a row.

And Zhao Laosi also found a force worker, and he has already excavated the foundation around the pit.

They fight at night.

Laying bricks and plastering cement overnight.

In order to increase the stability of the brick wall, a brick buttress in the shape of a field was cut at the bottom of the pit.

In three days, the pool was completed.

Fortunately, it didn't rain in the past few days, and the sun was strong.

The pool is 50 meters long, 10 meters wide and 2.5 meters deep.

Two of them are buried in the ground and fifty centimeters are in the ground.

The water inlet is connected to the spring.

The outlet is underground, and a deep trench is dug to lead to the reservoir.

After three days, the water began to be released.

I put it fifty centimeters first and exposed it to the sun for a day.

The koi fish were transferred into the pond.

Lu Changhua also deliberately checked the number, and sure enough, it was 800. The system didn't lie to me!

After that, the water depth will be increased by 50 centimeters per day.

Until the water is two meters deep.

Lu Changhua made an automatic device at the water inlet and outlet, which did not require human intervention.

As soon as the water level reaches two meters, the float connected to the outlet will pull the switch and start releasing water, and the water level will drop by 20 centimeters, and then the outlet will be closed.

When the water level of the inlet drops by 20 cm, the water inlet mode is turned on.

It is not until the water level reaches two meters that the water inlet is closed.

In this way, the cycle of one in and one out not only increases the oxygen content in the water, maintains the water quality, but also reduces the change in water temperature, so that the koi fish can maintain healthy growth in the pond.

Now these koi fish are under secrecy.

Even Zhao Laosi, who made a fish pond for Lu Changhua, didn't know about koi.

And these people in the reservoir have their mouths tightly shut, and no one can say anything.

Lu Changhua was afraid that someone would make it bad, and if he really threw a bottle of pesticide into the pool, he would not be able to find a place to cry.

Fortunately, this pool is inside the shoji and cannot be seen by outsiders.

Plus the edge of the pool is 50 centimeters above the ground, where do you look?!

This pond became the new home of these koi.

He had just breathed a sigh of relief, and Hu Dagui's words made his heart lift again.

"Changhua, it's okay to say it now, what if it's winter? There's no place to keep these koi! ”

Hiss~

Lu Changhua's heart tightened.

Sure enough, raising koi fish in the Northeast is really troublesome.

It's easy to say in summer, but in autumn and winter, the weather is cold, and koi fish are definitely not allowed to be in the open air.

Fortunately, Hu Dagui reminded him.

He pondered for days about this.

What is the method to keep these koi fish winter.

He thought of warm vegetables, of vegetable greenhouses.

It seems that you have to make a warm pool for the fish, and the current water temperature is about 23 degrees, and the warm pool must be kept above 20 degrees.

In order to raise koi well, Lu Changhua also went to the city to look for books on koi breeding in Xinhua Bookstore, but the result can be imagined, there is no at all.

Spent the afternoon at the hotel.

Business at Boiling Fish Village is as good as ever.

"Dad, I'll catch some fish and bring it to the store in a few days."

"Send less for now, try it."

Lao Lu was worried that changing the fish at home would affect the taste.

"Okay, let's try it first."

The next day he went home.

Fishing also has to be done, but the warm pond of koi fish also has to be done.

Now koi don't eat fish food.

Lu Changhua asked Hu Dagui and them to dig earthworms around the area.

Half a bucket can be dug up every day.

But these earthworms were thrown into it, and they were eaten quickly.

After the introduction of earthworms, the growth of koi fish has accelerated significantly.

But being close to wild earthworms is simply not enough.

It seems that I still have to find a way to breed.

In fact, in the past few years, there have been rumors of earthworm breeding outside.

Changshui Farm is already being raised.

I'll have to find someone to ask.

The matter of the warm pool cannot be delayed.

Originally, Lu Changhua thought that he would be able to add a greenhouse to the current pool, would it be okay?

On second thought, no.

You must know that the winter in the Northeast is minus thirty or forty degrees, and the ice can reach one meter and five to two meters.

And permafrost is about the same as ice.

In other words, the temperature should be maintained at least two meters or one and a half meters underground.

In addition, water in winter needs to be exposed to the sun to increase the temperature of the water and dissipate the chlorine in the water.

Anyway, this pool is not going to work now.

It has to be rebuilt.

Then let's build it, we can't watch these treasures freeze to death.

First, a large pond was dug to the west of the storehouse, twenty meters apart.

This matter has to be Master Lin.

He also did not contain a lake, and directly pushed out a deep pit of 20 meters from east to west and 50 meters from north to south.

The south side is only 30 meters from the spring.

Zhao Laosi can be regarded as having taken it.

With more than a dozen people working day and night, it took more than half a month to complete.

The large pond is surrounded by ring beams, just like building a house.

There are 50 walls on all sides,

Cement bricklaying, grouting.

The wall is three meters high, two meters underground, and one meter on the ground.

Six, five, and four meters high pillars are built in the pool.

The highest in the middle.

This is the column on which the roof is built.

The roof is a plastic cloth greenhouse.

In the greenhouse, an iron chimney running through the north and south is installed, and there are four flues.

To the north of this warm pool, that is, next to the shoji, a pit twenty meters deep was dug and covered with a roof.

Four large stoves were built inside.

This is where the stove burns in winter.

To heat this pool was specially built.

This pool cost Lu Changhua nearly 20,000 yuan.

While building this warm pool, he finally found a home to raise earthworms.

As soon as they met, the man began to complain.

It turned out that a relative of his came to him last year and said that their unit was promoting earthworm culture.

Free breeding technology, including education and education, and earthworm recycling.

He believed it, introduced earthworms, and began to breed.

This earthworm breeding is really simple, just smear some soybean oil on waste cardboard, and breed quickly with wooden boxes.

Soon more than twenty boxes were bred from the first box.

He pondered that it was going to be winter soon, so he sold it.

As soon as I looked for this relative, I pushed it tomorrow today, and the day after tomorrow, and never came to buy it.

Only now did he realize that people are just selling earthworms, where is teaching technology? Everything is a routine.

He raised too much, and he had no choice but to feed the chickens himself.

Now there are five boxes left.

"Well, you'll sell me all five boxes."

"That's a good feeling."

"I'll give you 100 yuan for these five boxes, and if you have more, you can drop it like that."

"Alright, alright, here you go."

People happily took ten pieces of unity, and Lu Changhua looked for Lao Lu and transported them back.

These earthworms are kept in the duty room on the north side.

There's an empty room here anyway.

He asked the master carpenter to make a dozen empty chests.

Waiting for the distribution of boxes.

This earthworm is indeed easy to raise.

I carry two buckets to feed the koi every day, and I can still provide for it.
