Return to the countryside to engage in industry

Chapter 48
When Yang Zhenyu reversed the car and came out, Han Laosi finally asked, "Brother, do you really know County Magistrate Qian?"

Yang Zhenyu nodded and said, "That's right!"

Driving a tricycle turned around and left.

Han Laosi did not forget to wave his hands and smiled: "Brother Yang, come and drink with me if you have nothing to do!"

After leaving Beimen Vegetable Market, Yang Zhenyu went to a pesticide seed company to buy herbicides and leveled two acres of sandy land.

The government's control over pesticides is also gradually strengthening. The highly toxic herbicides used to be sold in the market have been banned, but now they are sold and it is difficult to eradicate the roots. However, Yang Zhenyu is not too worried, and the soil has to be turned once before planting.

I bought the herbicide at ease and went home. First, I went to Luo Guiwen's house to return the tricycle. "Uncle, are you still busy?"

"Come back so soon?" Luo Guiwen stopped and wiped the sweat from his forehead, took the key, and asked curiously, "Why did you buy so much herbicide?"

"I'm going to dig out the two acres of land under Chaishan Mountain to plant fruits!"

"Xiao Yang, are you crazy? How can you grow fruit in that land? It's not good enough to grow corn." Luo Guiwen and Wang Xiuying had the same idea. Years of farming experience told them that nothing could be grown in that sandy land.

"Planting technology is developing very fast now. I need to understand it before doing it!" Yang Zhenyu said with a smile.

"That's true. I heard that fruits can be grown in the desert." Luo Guiwen sighed, "Hey, our generation can't keep up with the times. You work hard and bring the villagers to make money together in the future."

"No problem!", Yang Zhenyu held two boxes of pesticides and waved goodbye, "Let's go first, old man!"

"Okay, if you need help, make a noise!"

"Understood, thank you, uncle!"

When Yang Zhenyu returned home, he did not rest. He mixed the herbicide, carried the pesticide box on his back, and went straight to Chaishan. It was afternoon when he returned from work.

It will take some time for the herbicide to take effect, and Yang Zhenyu is not in a hurry. It is time to prepare for raising fish.

After having dinner with grandma, I called the owner of the forklift and asked him to send a forklift to Yangjiawan Pond for dredging tomorrow.

When the excavator arrived the next morning, Zhang Mingkang and his old cousin also came.

In Zhang Mingkang's eyes, the pond breeding project contracted by Yang Zhenyu is a big project in the village, and it is necessary for him to give guidance on the spot.

Yang Zhenyu was arranging work, and said to the forklift master, "Master, leave about [-] to [-] kilometers!"

The forklift master nodded.

Reserving a certain thickness of silt can ensure that the fertility and water quality of the pond are relatively stable.

This pond has never been dredged, and the silt in some places is nearly one and a half meters, which is very unfavorable for breeding.

Normally, the fish ponds are dredged every three years, which is almost a breeding cycle, when the fish is pulled from the net.

Excessive silt has three main hazards to fish pond culture.

First, the sludge contains a large amount of organic matter, which will consume a large amount of oxygen during the oxidative decomposition process of bacteria.

The bottom of the pond is originally the place where the oxygen is weakest, and the oxidation of the silt will cause the bottom fish to be hypoxic.

When the dissolved oxygen is below 3㎎/L, the growth of farmed fish will slow down. If the dissolved oxygen is below 1.5㎎/L, the fish will die in the pond.

The second hazard is the ammonia produced by nitrification of the sludge at the bottom of the pond and fish excrement. The ammonia will produce nitrite during the nitrification process, and the hydrogen sulfide produced by the decomposition of sulfide by heterotrophic bacteria in the sludge is all Highly toxic substance that may kill fish.

The third hazard is that the increase in pond silt will lead to deterioration of the bottom, which will breed toxic substances and harmful bacteria, causing water pollution and easily causing symptoms such as fish hemorrhagic disease.

Therefore, the dredging and disinfection work before breeding is very important.

Yang Zhenyu searched for information in detail, and also communicated with the owner of the fish fry in the city.

After finishing the dredging work today, Yang Zhenyu plans to expose the pond to the sun for another two days, and then sprinkle quicklime for disinfection.

After the preliminary work is done, you don’t have to worry about it anymore, just plant the grass elf cockscomb grass that was opened from the system treasure chest, and the water quality will be improved after that.

"Uncle Zhang, why are you here?" After arranging the forklift, Yang Zhenyu came over to pass cigarettes.

Zhang Mingkang said: "It is necessary for me to come to see the situation of the breeding project in the village."

"My cousin used to raise fish in Hubei. I'll call him up to see what I can do for you."

Yang Zhenyu smiled and said, "Thank you for your hard work on such a hot day!"

The old cousin smiled and said: "Looking at it now, Xiao Yang has done enough homework, so I don't need to talk too much.

Oh, by the way, let me ask by the way, Xiao Yang, how are you going to raise her? "

"Mixed breeding, mixed breeding is more cost-effective!" Yang Zhenyu responded, "Mainly grass carp and silver carp."

Polyculture is the core of domestic pond fish farming technology.

Silver carp belongs to the upper layer fish, grass carp belongs to the middle bottom layer fish, and herring and crucian carp belong to the bottom layer fish. Mixing these different types of fish in a pond can not only increase the stocking amount per unit area of ​​the pond, but also because various fish The baits required by different species are different, and various bait resources in the pond can be fully utilized to generate a mutually beneficial relationship, which can well prevent eutrophication of the water body.

Of course, the most important thing is that reasonable polyculture can increase production.

The old cousin nodded and said: "The silver carp is controlled at about 40%, the grass carp is 30%, and the remaining bottom fish is 30%. This ratio is the most reasonable and the output is also the highest."

Yang Zhenyu nodded and smiled, "I think the same as the old man!"

The old cousin pointed at Yang Zhenyu and smiled at Zhang Mingkang, "Look, I said that Xiao Yang's preparations are all done, I don't need to come, you insist on calling me, but the result is useless."

"No, no, my uncle has rich experience. I will ask him more in the future. I will check the breeding market later. If I expand the scale of breeding in the future, please ask my uncle to help, and I will pay you!" Yang Zhenyu laughed.

"Okay, Xiao Yang, when you need my old bone, just shout!"

The three were talking and laughing.

Before Zhang Mingkang left, he pulled Yang Zhenyu aside and said softly, "Speak up, Xiao Yang, your breeding scale has reached the standard of the national preferential policy. When the fish fry come back, you write an application material, and I will help you prepare the material." , Although the subsidy money comes down slowly, it is still money, which can save a lot of feed money!"

Yang Zhenyu nodded and said, "I see, Uncle Zhang."

"I heard from your aunt that you plan to reclaim the sandy land in the back mountain to grow fruits?" Zhang Mingkang asked with concern.

"Well, I just went to apply herbicide yesterday afternoon. After I release the fry, I will go out and investigate to see which fruit is more cost-effective?"

"You'd better discuss this matter with an expert. I have no right to stop you, but based on my experience, the risk is too great. You should think about it!" Zhang Mingkang patted Yang Zhenyu on the shoulder and said, "Even Zhang Uncle cares about you in private!"

"Got it, Uncle Zhang, thank you!" Yang Zhenyu smiled.

Judging from this, most of the villagers should know that they are going to reclaim the sandy land to grow fruits. No need to think about it, everyone must have the same point of view, and they are not optimistic about their doing so.

……

PS: I have something to deal with in the next two days, and I will update it in the evening.
