Ma Guanghui finally discovered the secret of a clean pig farm.
It turns out that there is a special "toilet" behind the pigsty.
It was a huge oval-shaped container.
The overall look is a bit like a large hot air balloon buried in the soil.
The rice fields produced by the piglets will be cleaned by the breeders.
It gives the impression that this is a set of containers specially used to collect Yoneda.
But what is the use of collecting rice fields?
Ma Guanghui studied for a long time and finally found a pipe extending from the ground not far from the container, leading to the masonry house next to it.

He immediately became interested.
I took a few steps forward, leaned by the window and looked in.
There is a cylindrical metal machine standing straight in the center of the masonry house.
At this time, it is rumbling in operation.
Because he was so close, he could even feel waves of heat.
Ma Guanghui is a little confused.
Of all the people here, he is the one who knows the most about the rice fields where livestock are raised.
After all, the Heyong People's Commune is a well-known large breeder. Not only the commune, but also the production teams below have breeding farms, and the scale is quite large.
Speaking of which, the more livestock you raise, the more trouble you will have.
One of them is feces disposal.
Because if animal manure is not processed in time, there is a high probability of causing livestock plague and causing huge economic losses.
On weekdays, the Heyong People's Commune dries poultry and livestock manure and uses it as feed.
However, due to the limited scale of cultivated land and poor road transportation conditions, more livestock manure can only be dug into wasteland and buried.
This not only caused waste, but also consumed a lot of manpower and material resources from the commune.
It can be said that handling livestock manure is Ma Guanghui’s most troublesome problem.
At this time, he saw a brand-new method of treating livestock manure. Although he did not understand its function, Ma Guanghui was still a little excited.
He walked to Cao Weidong and asked very humbly.
"Comrade Cao Weidong, I don't know what the feces looks like after being processed and what benefits it has."
Cao Weidong didn't give in and took a few people to the semi-open warehouse nearby.
There were streaks of dark brown liquid in the warehouse, as well as a lot of solid residue that looked like dirt.
Everyone came over to take a look, and then ran out because the smell was too strong.
Cao Weidong introduced to several people.
"This is the product of our factory, called a biogas digester. The feces of poultry and livestock can be piled in as raw materials. After the fermentation reaction inside the biogas digester, three treasures can be produced."
"The first treasure is these biogas slurries."
He pointed at the dark brown liquid.
"This is a very good fertilizer that can be applied directly outside the roots to increase crop yields and prevent and control some pests and diseases."
"Now the production team is using it, and the effect is pretty good."
Captain Qin Xiangyang nodded.
"Yes, after using this thing, the crops will grow vigorously. If you don't believe it, I will show you around later."
Everyone is not far away.
Several secretaries believed that Qin Xiangyang would not deceive them on this matter.
Cao Weidong continued.
"The second treasure is digesta."
"Burying them in the road can play a very good role in improving the soil."
"The most important thing is that these things are easy to store and transport, and can be sold as commodities."
At present, the domestic transportation system is not perfect. Most roads are full of potholes and are not suitable for transporting biogas slurry, a liquid that is not easy to store.
But solid digestate is different.
They are just like soil. They can be transported in bags, and they are not afraid of being shaken off along the way. It is not too convenient.
Several secretaries stared wide-eyed.
Isn’t this turning waste into treasure?
The most important thing is ease of transportation.
If the effect is as good as Cao Weidong said, it will be equivalent to adding a special product to his commune and increasing his income.
They all looked at Qin Xiangyang again.
Qin Xiangyang suddenly understood what advertising meant.
He patted his chest and gave a confident assurance.
"I use the reputation of the Qinjiagou Production Team to guarantee that what Comrade Cao Weidong said is true."
Several secretaries withdrew their gazes with satisfaction.
At this time, Secretary Xie of the North China People's Commune seemed to have thought of something.
His eyes widened and he asked in a tone full of horror.
"Wait a minute, you just said that the biogas pool can produce three treasures. Could it be that the third treasure is... biogas!"
The scene became quiet.
Biogas!
This is biogas!
Higher-level departments have always said that they want to promote biogas, and they usually promote the work, but it is only superficial.
After all, they don’t even know what biogas is like, so even if they want to promote it, they have nowhere to start.
Unexpectedly, Cao Weidong has already sold biogas as a product?
Cao Weidong smiled implicitly.
"Yes, the third treasure is biogas. This thing is a real treasure...Captain Qin, go and demonstrate it again."
Qin Xiangyang responded, turned around and ran outside.
Several secretaries and some monks were confused.
They looked at Cao Weidong with confusion.
Cao Weidong signaled several secretaries to wait quietly.
Time passes minute by minute.
Others were fine, but Ma Guanghui was a little impatient.
He scratched his neck and said.
"Comrade Cao Weidong, if you have anything to do, just tell me directly. I usually hate showing off..."
But before he finished speaking, a sizzling sound of electricity sounded.
This is the unique sound of a large speaker.
Several secretaries couldn't help but shudder.
This voice is too familiar to them.
In the commune, everyone spent almost every night listening to the loudspeaker.
Could it be that the Qinjiagou production team in such a remote place also has radio access?
Why haven't I heard of it before?
At this moment, the sound of the trumpet finally became clearer.
[Hey, hey, hey, hello everyone, I am Qin Xiangyang...]
[Now let us use the warmest attitude to welcome several commune secretaries to our Qinjiagou production team to inspect the work...]
This chapter is not over yet, please click on the next page to continue reading!
Ma Guanghui knelt down directly to Cao Weidong!
This is not a radio station at all!
This is a radio station!
It’s the kind of radio station that requires power to be used!
Ma Guanghui asked you in a dry and disbelieving voice: "Comrade Cao Weidong, can biogas... also generate electricity?"
Cao Weidong said with a smile.
"Yes, our Zhenhua Biogas Plant has mastered biogas production and practical technology, and can provide you with practical biogas solutions, supporting biogas production equipment and biogas power generation equipment."
"And as long as there are enough rice fields for poultry and livestock farming, biogas can be produced and two kinds of fertilizers can be produced at the same time. It can be said to be natural, environmentally friendly and pollution-free."
"If you use our company's biogas equipment, we will also provide additional guidance on poultry and livestock breeding to help you build a farm and meet the conditions for utilizing biogas."
"Of course, in places like Heyong People's Commune, which are large farmers, as long as the farms are modified, they can be well adapted to the biogas digesters."
In this era, the product concept proposed by Cao Weidong is completely beyond the times.
Not to mention several secretaries, even our own people like Xu Aiguo and Shi Man were shocked.
They never knew that products can also be linked to services and provide solutions to problems based on products.
This is amazing.
Ma Guanghui's eyes were red and he couldn't wait to ask.
"How much does a biogas digester cost! I want to order ten sets!"
Cao Weidong said without changing his expression: "It's not expensive. It only costs 3,000 yuan to build a biogas digester. However, the price of practical biogas equipment ranges from 1,000 to 10,000 yuan."
