……

Now Gu Zhongyi and his family are also convinced of this daughter, she is simply a jack of all trades, it seems that no problem can stop her, how can she understand everything?

After listening to the analysis of the condition, I can only blame the two of them for their poor skills, which caused a "big hole" in fish farming that year, and lost all the money. Fastest updates

Seeing the convinced expressions of the two people, Gu Fanxin did not pretend to be profound, "In fact, these things are all obtained by the predecessors through exploration and accumulated experience, as long as you study hard, it is not difficult to master." Since you are ready to continue your work, I will buy you books on this subject and send them back when I go back, so that you can study more. ”

Xu Zhaodi's face was difficult when she heard it, she didn't know much words, and she didn't read a book seriously.

"If you don't understand something, just ask Uncle Zhongxin and Gu Pengcheng, and you will understand it if you look through it more. ”

"Yes, yes, it's really good to read more," Liu Lanzhi nodded and agreed, she was originally an old man who couldn't read a few words.

Later, after Niuniu bought herself the Bible and the Hymn, she learned to sing and praise the Lord with other brothers and sisters every day, and then read books, many words were naturally recognized, and the Bible stories were almost familiar.

"I'm that old...... Is it easy to learn?

"Chairman Mao, his old man didn't teach us, live to be old, learn to be old. I'm all there is to be when I'm this old, you can do it. ”

At such an age as myself, I picked up the "Hymn" and read it for a long time, and I knew it, and there is a saying that 'practice makes perfect', I believe that my daughter-in-law is so young that she will not be as good as an old woman with old arms and legs.

Xu Zhaodi was silent now.

The comrades in the navy can see it clearly, the little wife still wants to pull her mother's family out of love, Niuniu is always so kind, and her heart is too soft.

Gu Fanxin also had this intention.

It is better to teach people to fish than to teach them to fish, and it would be better if we could slowly lead them on the road of becoming rich through hard work with their own hands.

Let them get a sense of accomplishment through self-reliance, hard work, sweat, and no longer always keep their eyes on themselves, wanting to get those unrealistic things for nothing.

After all, during the time when the fish pond was contracted, the couple was also very enthusiastic and enthusiastic, eating and living at the fish pond.

"Fish farming is really hard work, and the two of us have been living and eating the fish pond since we contracted the fish pond. ”

Xu Zhaodi was also very emotional when she said it, in fact, she is really not a lazy person, and when she really has a head, she can still give up her body to do it.

Don't think that fish farming is a simple job, in fact, fishing farming is a delicate work that requires both care and patience, and if you want to carry out a similar "fishing business model", you really have to have a set.

Now that the goal has been determined, and the fishpond fishing garden has been taken over by their family, it must be done well.

"They're just recycling the food chain. Gu Fanxin popularized the so-called food chain recycling knowledge to his parents.

There is a husband and wife who have a fish pond connected to the pig barn.

I heard that there are pig houses built around the fish pond opened by their family, and each pig house raises more than 10 pigs, and the urinal of the pig house leads directly to the fish pond.

Pigs have limited digestive tract capacity, and food that is not fully absorbed and utilized by the intestines can still be used after forming feces, so they use pig manure as fish feed.

In summer, when pig manure is not enough, rapeseed cake is used as a feed supplement.

The fish fed in this way are delicious and no different from wild fish.

In addition, the family also grows vegetables and poultry by the fish pond, which is all "green food", and guests who come to fish or visit have a source for lunch meals.

"Catch wild fish and eat farm food" became a brand that attracted people from the surrounding cities.

The main rearing techniques of pond fish culture include polyculture and dense culture, rotation fishing and release, daily management and integrated management.

The 5th century B.C.'s Book of Fish Farming is the world's earliest book on fish farming. In the Han Dynasty, carp farming was very common.

In the Tang Dynasty, the monoculture of carp was developed into a variety of fish polyculture such as grass carp, herring, silver carp and bighead carp, which was an important breakthrough in pond fish farming technology.

By the Song Dynasty, it had been quite developed to catch the above four kinds of fish fry from the Yangtze River for rearing, and it was realized that these fish could not reproduce naturally in ponds.

In the Ming Dynasty, there was the germination of advanced fish farming technologies such as timing, positioning, quantitative, qualitative feeding and rotational fishing, and there were detailed records of the construction of fish ponds, the density of stocking and the matching of fish species, bait, fertilization, and treatment of fish diseases.

In the middle of the Ming Dynasty (15th and 16th centuries), mulberry trees and fruit trees began to be planted on the fish pond embankments in the Pearl River Delta, and fish farming, silkworm farming, and crop planting were combined for comprehensive management.

It is the characteristic and core of pond fish farming technology in China to stocking fish of the same age and different sizes of the same species with different habitats and eating habits in the same water body.

Polycultured fish should be habit-related, with similar requirements for water quality and water temperature (during the growing season). Ideal fish for polyculture are silver carp, bighead carp (pelagic fish), grass carp, bream (pelagic fish), carp, crucian carp, dace, herring (demersal fish), etc.

The polyculture of fish inhabiting different water layers can make three-dimensional use of the water space.

The density of stocked fish can be increased significantly compared to monoculture.

The feces of grass carp and herring carp are not only fertilizers for cultivating plankton, but also provide a large amount of organic detritus and breeding bacterial colonies for silver carp and bighead carp to filter feed.

Carp, mrigal and crucian carp can remove bait residues and improve water quality. It not only has the advantage of making full use of water bodies and increasing yields, but also has the effect of reusing bait and improving water quality.

Polyculture of fish of the same species and different ages and sizes also provides conditions for the harvesting of batches in one production season and balanced marketing, and at the same time the cultivation of large-sized fingerlings for the next year.

Polyculture of fish should be divided into primary and secondary, and the main fish culture is the main object of feeding and feeding management.

Paired with fish plays a role in making full use of the water body and the reuse of bait. There are four main types of polyculture in pond fish farming.

Grass carp and silver carp-based polyculture types are the most common types. It is characterized by a wide range of sources of feed and fertilizer, low cost, high yield and economic benefits.

The stocking specifications of grass carp are 10 grams, 50 grams and 150~500 grams, and the stocking specifications of silver carp are summer flowers, 50 grams and 200~350 grams.

The stocking weight is about 45% and 30% of the total stocking volume (about 150 kg), respectively, and the polyculture of bighead carp, bream, crucian carp, etc.

Grass carp, bighead carp and mrigal are the main polyculture types

The type commonly adopted in the Pearl River Delta.

The local water temperature is high, the growth period is long, the water quality is relatively fertile, and it can be stocked and harvested many times a year, especially the bighead carp.

At the same time, silver carp, rohu and other species can be mixed and an appropriate number of snakeheads and eels can be mixed to increase profits.

Gu Zhongyi and his family sat upright, and they both listened seriously. This daughter is still sincerely for the good of her family.

In the past, because of their assertions when they were children, they were always so paranoid and blind, and they didn't give her a good face......

For the first time, they felt guilty.
