Cao Weidong found Qin Xiangyang, the breeder of the production team.
Hearing that Cao Weidong wanted to visit the pig farm, Qin Xiangyang welcomed him with both hands and took Cao Weidong into the pig farm.
Looking at the clean pigsty and piglets, Cao Weidong praised him repeatedly:
"Yes, you are indeed attentive."
"Your teaching is still good."
Qin Xiangyang's tone was full of sighs.
In the past, when they raised pigs, they always had problems such as high morbidity, high mortality, and high feed consumption.
Later, the ventilation renovation of the pig house was carried out according to Cao Weidong's method, and daily disinfection and pig manure cleaning were added. The pigs have not been infected with diseases for a long time.
It's still the same feed as before, but the pigs fed out are healthier than the last, and the meat is also plump.
Cao Weidong smiled and said: "There are books on scientific breeding in the city, but you have few exposures to them."
In his previous life, he lived in an era of bombardment of advertisements. Some advertisers selling organic pork wanted to post the entire process of raising pigs in their promotions, just to prove the quality of their own pigs.
Cao Weidong has seen similar advertisements.
Even if you don’t raise pigs yourself, you still know simple things like disinfection, ventilation, and prevention of swine fever. You can directly copy the concepts and use them on the pig farm of the Qinjiagou production team.
The result is not bad.
The pigs are white and fat.
It's just that the whole machine has been changed to all manual work, which is a bit laborious.
But then again, in the commune era, people were the least valuable.
Especially in the production team, the breeders can get full work points without having to work, which is a job that many members envy.
"Old people say that pigs are born dirty. They poop after eating, but I feel that pigs also like clean things. If the place where they live is clean, they will be happy, gain weight easily, and are less likely to get sick." "When I went to the commune to hand in pigs a while ago, the commune cadres said that the pigs we raised were of good quality, and we wanted to organize breeders to come and learn from them."
Qin Xiangyang said proudly.
It can be seen that he really put his heart into it, introduced new things from the old, and made many improvements that fit the current situation of the production team.
Cao Weidong visited a circle of pig houses and looked at the manure pit of the pig house, and he knew it in his heart.
Biogas digesters can be built.
But how to convince Qin Youliang to build a biogas digester is still a problem.
After all, it is easy to collect firewood in rural areas, and it is not uncommon to boil water for cooking. For the production team, the biogas digester is just an exquisite decoration, which is thankless.
After thinking for a long time, he suddenly had an idea.
He hurriedly found Qin Xiangyang and suggested building a trial biogas digester.
Qin Youliang was a little puzzled.
"Teacher Cao, what is a biogas digester?"
Cao Weidong said: "It is a thing that can turn waste into treasure. It can turn pig manure into biogas and make your place electrified."
Qin Youliang's eyes went straight.
"What, it can still be powered on."
Qin Youliang almost got crazy thinking about turning on the electricity.
It is no exaggeration to say that if the production team could have access to electricity, their living standards would suddenly rise to several levels.
Qin Youliang hurriedly wanted to gather everyone to start building this "biogas pool".
Cao Weidong quickly stopped him.
"Wait, let me explain the situation clearly to you first. I can provide drawings for building a biogas digester, but you need to prepare the materials yourself."
"And the biogas digester relies on pig manure. With the size of our production team's pig house, I estimate that we can build a small biogas digester of 6-8 cubic meters. The biogas output is limited, and the construction of the biogas digester requires the use of cement, red rotor, and
Paired with industrial components such as biogas lamps and generators."
After hearing that these materials were needed, Qin Youliang also hesitated.
After thinking for a long time, he asked: "Teacher Cao, can the biogas production supply the electricity consumption of a radio station?"
At this time, the production team has little information. If a radio station can be built, it can deliver agricultural information, publicize commune policies, mediate neighborhood disputes, and increase leisure and entertainment, which would be very important to the commune members.
Cao Weidong thought about it and thought it should be fine.
Qin Youliang slapped his thigh.
"Then let's do it. We have our own brick factory, which can burn red bricks. A while ago, a buyer came to us to purchase agricultural auxiliary products. He is from a cement factory, and he can also buy some cement through connections."
"As for the components of the mechanical industry, I need some help from Mr. Cao, but we can exchange them with supplies."
Cao Weidong thinks this method is feasible.
He still has the task of trial-building domestically produced cars.
I will definitely deal with the old masters in machine repair shops and machinery factories.
When the time comes, just ask the masters to help him build a generator component.
Anyway, he can provide drawings, which undoubtedly saves a lot of things.
"Okay, let me figure out the mechanical components. Let's build the biogas digester first and put it next to the pig house."
Then, Cao Weidong asked Qin Youliang to find paper and pen on the spot, think about the content, and draw a design blueprint for small household biogas.
Qin Youliang called over some old masters from the brick-burning factory.
They are all the main force in building biogas digesters.
The old masters looked at it for a long time and were amazed.
To be honest, they didn't understand it at all.
It just looks like the structure is quite simple.
It's nothing more than adding a roof to the manure tank and building an insulation cover.
A master craftsman asked doubtfully: "Teacher Xiao Cao, can this thing really generate electricity?"
Seeing how careless the masters were, he felt that it was necessary to explain clearly and let the masters realize the dangers of biogas.
"This biogas digester is a container for producing biogas. Biogas is very dangerous. You must be careful when building it, because biogas will burn when exposed to fire and may even explode."
"Will it explode?"
The old masters were shocked.
They were all old people who had experienced the war. They immediately realized the dangers of methane and became serious about it.
Cao Weidong explained the key points of construction to several master craftsmen.
I was busy until lunch time before explaining the architectural blueprint clearly.
Qin Youliang arranged lunch again.
After eating, Cao Weidong and Qin Youliang said hello and prepared to go back.
It takes time to raise materials for building biogas, and it also takes time to build a biogas digester. He estimates that it will take at least until around the Chinese New Year to complete it. It's okay to stay here now. He can just come over to inspect it after it is completed.
After Qin Youliang heard this, he immediately arranged for an ox cart to take the pigs to the steel rolling mill.
Cao Weidong also paid Qin Youliang a clear settlement according to the purchase price provided by the steel rolling mill, and then left with everyone's reluctant eyes.
Qin Jingru even sneaked up to Cao Weidong and said, "I heard that you and my cousin live in a large courtyard. I will go and play with my cousin in a while."
Cao Weidong smiled and said, "Okay, then I'll wait for you in the city."
After waving goodbye to everyone, Cao Weidong followed a few bullock carts on the road. It was near evening when they finally arrived at the steel rolling mill.
Cao Weidong looked at the sky and said, "It's already very late. I'll ask the factory leader to arrange a place for you to stay for one night and go back tomorrow."
Thank you very much to several members.
At this moment, he saw a group of people rushing out of the steel rolling mill with murderous intent, including Zhang Haiming.
