It’s no wonder Professor Liu is so excited. Ecological green pig farming is a very complete set of pig farming techniques in later generations.

The pig house designed by Zhang Lang faces north and south, is 6 meters wide, 20 meters long and 3 meters high. It is divided into four small pig farming ponds by partition walls. A five-meter-wide outdoor activity field is also left on the south side.

Anyone who has raised pigs in the countryside knows that the smell in the pig farm is really very heavy and it also has a great pollution to the surrounding environment.

The ecological filial piety bed designed and used by Zhang Lang is a very good ecological breeding technology in later generations.

In the pig house, dig 80 cm of the soil and use

Corn stalks, sawdust dust, and feces or loess are fermented and reproduced in microbial fermentation beds to form a microecological fermentation bed factory, and use this as the lining for pigpens.

The pig's arch turn habit is used as a machine processing to make pig manure, urine and bedding fully mixed. Through the decomposition and fermentation of the fermentation bed, the pig manure and urine are fully decomposed and transformed. Microorganisms feed on undigested pig manure as bait and reproduce.

With the treatment of pig manure and urine, the odor disappeared.

At the same time, a large number of microorganisms that reproduce and grow provide pigs with inorganic nutrients and bacterial proteins to be eaten by pigs, thus complementing each other, turning the pig house lining fermentation bed into a micro-ecological feed processing plant, achieving the purpose of odorless, odorless and harmless. It is a pollution-free, emission-free, and odorless new environmentally friendly ecological pig farming technology.

The fermentation bed is to give livestock a natural ecological primitive living environment during the breeding process. The fermentation bed mainly includes two aspects: improving the living environment and feeding.

"Professor Liu, I actually just proposed a thought. There are many technical problems that need to be solved by experts like Professor Liu." Zhang Lang knew very well the problems in the planning book he proposed.

To put it bluntly, Zhang Lang watched the agricultural program of Central Set 7 when he was bored in his later generations. It seems that he has never actually operated it.

Zhang Lang didn't know what he said, but how to operate it specifically and how to control the beneficial bacteria produced by the filial piety bed.

If Mayor Li had not promised to send experts to guide the production, Zhang Lang would not have chosen such a pig farming plan.

At most, it is like raising roe deer, surrounding a hill for free.

"These are all small things. I thought about it yesterday. I also had some ideas about how to control the filial piety of the ecological bed." Speaking of his major, Professor Liu immediately became confident.

He talked endlessly about some of his thoughts in Zhang Lang.

Zhang Lang was overjoyed when he heard this. The ideas he proposed were basically improved by Professor Liu, and he further proposed some new ideas based on Zhang Lang.

As for the waste caused by experiments such as new ideas and new technologies, it is not a problem at all. Compared with the economic benefits and political resources obtained by the first to take the lead, these are all a drop in the bucket.

"Secretary Zhang, I heard that you plan to use the wild boar king as a breeding pig. This idea is great. Wild boars have strong ability to resist diseases and have tenacious vitality. Moreover, hybridization with domestic pigs can also solve the shortcomings of wild boars' poor reproductive power."

Professor Liu said that the fertility of wild boars is one of the species with relatively strong fertility in nature compared to domestic pigs.

"Professor Liu, just call me wolf cub. Secretary Zhang... Secretary Zhang's call, I'm really a little uncomfortable. You said so well. I'll ask Professor Liu for the pig farm. You can just talk to me whatever I need to do. I will obey the order and follow the command." Zhang Lang happily held Professor Liu's hand and said.

Zhang Lang felt a little unreal. All this went too smoothly. He really wanted to plant a greenhouse. He came with a botany expert professor; he wanted to raise pigs, so Mayor Li sent a biology expert to come.

"Okay, then I'll call you a wolf cub. I heard that the old people in the village call you that." Professor Liu didn't know how to be polite, and agreed with a smile.

The old intellectuals are like this, they are upright and will not turn. It is precisely because of this that they can make achievements in their respective professions.

Later generations Zhang Lang once heard a second-generation official evaluate these experts and scholars who are engaged in technology. "Good technicians have secondary diseases, and the best experts are not good experts."

Zhang Lang believes that although this is a bit extreme and not very nice, it vividly describes the personality characteristics of experts and scholars.

"I suggest you raise pure wild boars together. Wild boars are more fragrant than home pork. Although there is no shortage of wild boars in the mountains, wild boars are not endless. There will always be a time to catch them." Professor Liu gave Zhang Lang another suggestion.

Zhang Lang suddenly felt awe-inspiring. This was the vision of experts and scholars. Zhang Lang, who had lived again, knew that in two thousand years, the country listed wild boars as second-level protected animals and prohibited the random hunting of wild boars.

"Okay, you have the final say in the pig farm. When the pig farm is built, I will send you some people to help you. You can do whatever you want. Who dares to disobey? I will break his legs." Zhang Lang glared and promised.

Professor Liu was scared and said to himself, "This wolf cub has such a strong murderous aura. He is worthy of being just coming off the battlefield. I guess his life is indispensable."

Zhang Lang and Professor Liu stood outside the pig farm and talked for a whole morning, until Tang Feifei came to deliver water to him.

Tang Feifei seemed to have forgotten what happened yesterday, and still greeted Zhang Lang naturally, "Don't talk about wolf cubs first, drink some water! Look at your lips are so sloppy."

Zhang Lang took the ceramic jar with the August 1st Army seal printed and handed it to Professor Liu, "Come to Professor Liu, after saying so much, you drink some water first to moisten your throat."

Professor Liu didn't dislike it, so he took it and drank the water dry.

I talked for a whole morning and didn’t feel the investment I had just talked about. As soon as I stopped, my throat was about to smoke.

"Do you want another cup for Professor Liu?" Zhang Lang asked from the side.

"Okay! This mountain spring water is still delicious, so let's have another cup." Professor Liu was not polite.

Tang Feifei hurried to Professor Liu to Shangshui again.

After drinking the water, Professor Liu said goodbye with great vision and left.

Zhang Lang held the jar and waited for Tang Feifei to pour water for himself. As a result, Tang Feifei rolled her eyes and said, "If you want to drink it, I will leave if I don't drink it!"

Zhang Lang was a little confused and had to smile with him, "Sister-in-law, I really didn't mean it yesterday!"

"Big pervert!" As he said that, he poured water on Zhang Lang.

"Sister-in-law...thank you!" Zhang Lang drank all the water in one breath.

"Hmph! I'm too lazy to pay attention to you!" After saying that, he turned his waist and left without looking back.

Zhang Lang looked at Tang Feifei's back as he walked away, touched his head and smiled foolishly.

"Uncle Wolf,! Haven't you taken it yet? Do you want me to teach you a few tricks?" Erpang came over and asked.
