Duan Wenchang smiled: "What's this, no matter how small the problem is, it's also a problem, I'm very welcome, please say." ”

"Three questions I want to ask. Jiang Yuanguo paused and continued: "One: Regarding earthworm farming, what should I pay attention to when using greenhouse farming?"

"Second, what is the proportion of feed for earthworm farming, and what are the general needs as feed nutrients for earthworms?"

"Third, about earthworm farming, how about the periodicity, how to improve the survival rate of earthworms, box culture, pit culture, pot culture and the use of greenhouse culture, which of these classification focuses on which advantage is stronger?"

"Mr. Duan, through your speech just now, I have a preliminary understanding of the relevant content, but I still want to ask you to analyze the advantages and disadvantages of the above four breeding methods. ”

These three problems are not tricky, and they can be said to be relatively primary. But these questions just hit the content that Jiang Yuanguo needs most now.

He has checked a lot of information on earthworm farming, from building a breeding environment, to starting breeding, to selling, a series of contents have been understood.

But just knowing is not the same as being able to fully understand the various techniques in it.

And what he lacks most is the information on the above three issues.

Now it's an exchange meeting, where questions can be asked and answered. And everyone is a farmer, for these problems, basically will come to the non-refusal.

Therefore, this is also one of the reasons why Jiang Yuanguo must participate.

If you do it, you have to do it to the best of your ability.

It just so happened that there was such an opportunity in front of him now, and it was the best thing to know.

Duan Wenchang smiled: "Let's talk about the first question first, the precautions for using greenhouse farming. In fact, this answer, the third question you mentioned, the four breeding methods are all applicable to the main points I said. ”

He paused and continued: "Regarding the precautions for earthworm breeding, one is temperature, the second is humidity, the third is the environment, the fourth is food, and the fifth is the cycle. ”

"In terms of temperature, the most suitable temperature for earthworms is around 20 degrees Celsius, neither cold nor hot. This is the most suitable temperature environment for earthworms to grow. In this environment, earthworms grow faster. This is a suitable temperature that has been studied for a long time. And the temperature control must be well controlled, and the temperature control is good, so that the earthworm can have room to move. That's the first point. ”

Jiang Yuanguo nodded and casually recorded this incident in his diary.

"The second point is the humidity of the land. With the temperature, we must maintain the wetness of the land, and the humidity must be controlled. Because you and I and everyone know that the environment where earthworms grow is in a humid and mild environment. In this temperature environment, earthworms can grow better. ”

"The proportion of humidity should be kept at 65% soil wetness. In this way, the earthworms can drill freely in the soil, and the soil will not lose its wetness and stickiness. The space for growth will be improved. ”

"The humidity is a good solution, as long as the proportion is adjusted accordingly with silt and mud. Everyone knows how to measure humidity, so I won't go into detail here. The next point is the third point, the environment. This environment can be understood as a repeated understanding of temperature and humidity. The environment is the living space. Only when the temperature and humidity are relatively suitable. Earthworms can grow well and grow fast. And, most importantly, no matter which of the four seasons you have, as long as you control the temperature and humidity, in general, the living environment is already a particularly good situation. ”

"Of course, we can't forget about the feed for earthworms. As for feed, as we all know, earthworms are omnivorous annelids. They can eat a wide variety of foods, except for plastic, rubber, glass and metal. ”

"He can eat humus like plants, fungi, vegetables, animal manure, pig manure, and bacteria in the soil. ”

"Therefore, we need to adjust the proportion of ingredients in the earthworm food to ensure that the growth rate of the earthworm will not cause other problems due to adjusting the wrong feed ratio. ”

"When it comes to food, there's one thing that needs to be the most important. This is very important for the growth of earthworms. Duan Wenchang paused and continued: "These feeds, or organic wastes, must be accumulated for half a month, and then rich water is added to keep the moisture of the feed at 60%-70%, and then decayed and fermented three to four times before the earthworms can be eaten. Otherwise, if the feed is not fully fermented, the earthworms will die once they are eaten. I think this is an outcome that a lot of my peers don't want to see. ”

"Of course, we can take a small amount of food to let the earthworms into the feed before feeding the rotten bait, if the earthworms are unwilling to enter, it means that the bait is not completely fermented successfully, and the earthworms cannot be eaten, and they need to be fermented again until the earthworms enter the bait and start eating. ”

"Let's talk about the last question that this gentleman raised, which is cycles. The growth cycle of earthworms is generally 20-30 days, and the longest is not more than 35 days, otherwise there will be problems with the traits and characteristics of earthworms. Of course, you can also consult experts to customize the corresponding breeding cycle according to the environment of the earthworm farm, which is generally as short as 20 days and no more than 40 days. The 30 days I am talking about is just a pertinent suggestion, and everyone should adjust accordingly according to the environment in their own farm. ”

"Of course, in terms of breeding stocking, it is generally 10,000 young earthworms per square meter that are close to the hatching date, and this density is sufficient. ”

"In addition to this, we should also pay attention to the harvesting, when the earthworms per square meter reach about 20,000, the large earthworms should be harvested in time and divided into piles. And if you are inbreeding, the earthworm will gradually decline, so it is best to change the earthworm species every three to four months. After the large earthworms are harvested and stacked, the bait should be replenished in time. ”

“……”

All kinds of professional knowledge came out of Duan Wenchang's mouth, and during this period, other people raised some relevant questions and opinions to Duan Wenchang, and Jiang Yuanguo recorded them one by one after hearing them.

These things are the most precious materials for his next side farming.

Moreover, he was very lucky today, after sorting out the information on earthworm farming, the host also invited him to explain.

He recalled his efforts in the past year, from the beginning of the idea, to the implementation, to the study, to the construction of the factory, to the development of sales channels, to the expansion of the scale.

Step by step, the efforts and hardships are probably only understood by a few people in the farm.

Thinking of this, he stood on the stage and smiled: "Colleagues, hello everyone, my name is Jiang Yuanguo. ”

“……”

This exchange meeting lasted for a long time, and Zhao Lei, Jiang Yuanguo and Hu Hanliang came to the stage to exchange their breeding experience.

All kinds of questions, all kinds of laughter, everyone happily got the answers they wanted.

That's communication, that's meeting.

Put the problem on the bright side, solve the difficulties when there are difficulties, and deal with the problems when there are problems.

Everyone is working hard for their own different types of farms.

Finally, the exchange meeting ended.

After that, the next step is the interpretation of a national policy.

To sum up, the state will vigorously support the aquaculture industry and farmers, as long as they work hard, the state will give the corresponding policy approval and financial subsidies.

These contents are all implemented in fact, and it is precisely because of the support of national policies that Jiang Yuanguo Duan Wenchang and them have achieved their current achievements.

It can be said that without the vigorous support of the state, perhaps it would be difficult for Jiang Yuanguo and them to achieve their current achievements.

……

During the meal, Jiang Yuanguo happily looked at the contents of the diary, and it can be said that he has gained a lot from coming over today. He couldn't have been happier.

"How is it? Today's exchange will be good, right?" Zhao Lei smiled.

Jiang Yuanguo nodded: "Every farmer in Li Tou in the exchange meeting can be called a breeding expert, haha." In the process of communication, a lot of small questions, big problems, the content that was confused in my mind before, listening to the above words, I was simply stunned, many things that originally had only one way to deal with them, there are many options, and the cost performance is also very appropriate. It was a really interesting meeting. ”

"That's because I talked a lot about the breeding industry at the exchange meeting, so my factory can develop. These are all talents, planning together, discussing together, and discussing together, in order to have better development. ”

Jiang Yuanguo deeply thought so, this is a fact.

After eating, the three of them briefly exchanged a few polite words, and Zhao Lei drove Hu Hanliang away. Jiang Yuanguo was going to the city to pick up his daughter.

Jiang Yuanguo looked at their departing car and smiled. Today, he was in a particularly comfortable mood, and learned a lot about the sideline earthworm farming, and learned about some detailed rules about pig raising, which are really valuable materials and resources for him.

It has a greater effect on his future farm.

Jiang Yuanguo became more and more confident.

At four o'clock in the afternoon, Jiang Yuanguo received his daughter and returned directly to the farm, and saw his wife Du Yunfang, Su Wanwan, Qin Hao, and Jiang Xiaoliang changing the feed, so he put down his backpack, disinfected it, and participated in the labor army together.

After doing this, it was already past six o'clock, and now that the scale of the farm has expanded, there are more young pigs, and the things to deal with have become more complicated. But everyone didn't feel tired, but lived a full life.

After all, it's all your own business.

After doing this, Jiang Yuanguo made a phone call with Jiang's father, and did not go to the mountains again, but planned to have a meal in the farm with everyone.

Everyone sat around and happily made dinner on the farm.

Su Wanwan served rice to everyone and said with a smile: "Brother Jiang, how do you feel about participating in the exchange meeting this time?"

Jiang Yuanguo smiled, he took out the bag from the side, and handed the diary inside to Qin Hao: "This harvest is very big, it is full of notes I made at the exchange meeting, these are the most useful precious materials for our farm." ”

Qin Hao was originally eating, he took the diary and glanced at it, then took a closer look.

In an instant, he put the dishes and chopsticks on the table, picked up the computer from the side, and went straight to work.

Everyone was a little stunned for a while, they didn't expect this information to be so attractive to him, and they couldn't even take care of eating.
