Return to 78: Why are all the Americans panicking about doing scientific research?

The combined age of Zhang Weimin and Xu Haodong is over a hundred years old.

I wouldn’t dare say that I’ve seen everything, but I have gone through decades of ups and downs.

I have never seen anything as strange as today.

Lin Kaifeng came to the Agricultural Science Research Institute and said straight away that he wanted to buy imported Landrace piglets.

Judging from what he said, Lin Kaifeng has a deep understanding of imported Landrace pigs.

Although I don't know much about the details, I am definitely not a layman overall.

What surprised the two even more was Lin Kaifeng's identity.

He was neither the director of the commune nor the team leader or secretary of the production team.

Instead, he is the head of the Northern Machinery Company which has become famous recently.

This is what and what.

Zhang Weimin said with a complicated expression: "Comrade Lin Kaifeng, are you really kidding us two old guys?"

"We have heard a little bit about your Northern Machinery Company. You sell electronic products and agricultural vehicles. How come you are starting to raise pigs?"

Xu Haodong was also puzzled.

As the saying goes, every other line is like a mountain.

If you want to set up a pig farm and breed a large number of Landrace pigs, it is definitely not something you can do just by thinking.

"Comrade Lin Kaifeng, you should reconsider this."

Even though Xu Haodong was extremely worried about promoting Landrace pigs, he would not let others suffer losses because of his momentary impulse.

Agricultural scientists are scientists too.

As a scientist, you must seek truth from facts.

Lin Kaifeng smiled and said, "Two experts, maybe in your opinion, it is a fantasy for a machinery company to engage in livestock breeding, but what I want to say is that every word I say is not a joke."

"I once worked in the Dongshan Brigade, where I was sent to work in the countryside. The brigade already had the ability to produce biological feed."

"People don't have enough to eat, so naturally they don't have extra food to feed pigs. That's why people are dissatisfied with the fact that the lean meat rate of Landrace pigs is higher than the fat meat rate."

"For ordinary people, pork fat is not only a food to satisfy their appetite, but also a major source of edible oil."

The two nodded, and Xu Haodong said, "Since you know this, why do you still raise a large number of Landrace pigs?"

Lin Kaifeng said: "This matter cannot be explained clearly in a few words. Let me first tell you what biological feed is. What do you think?"

"Okay, we're all ears."

Both of them were quite interested in the biological feed that Lin Kaifeng mentioned many times.

As the name suggests.

Biological feed is definitely different from the current grain feed.

If Lin Kaifeng can really solve the feed problem of feeding Landrace pigs.

It doesn't seem to be a crazy idea to open a pig farm and raise a large number of Landrace pigs.

Kaifeng started from the beginning.

The so-called biological feed is also called straw feed.

The corn stalks and rice stalks left over from the autumn harvest are dried in the sun.

Use sunlight and wind to dry out most of the moisture in the straw.

But it can't be dried completely.

A certain level of humidity needs to be maintained.

The straw is then cut and crushed manually or mechanically.

While processing the straw for the second time, auxiliary materials rich in protein such as bones and earthworms must also be processed.

Evaporate all the water in it.

Grind it into powder and add it to the straw for fermentation.

Utilize the action of microorganisms to accelerate the decomposition of cellulose and improve the internal nutritional content.

During this period, the fermentation time, temperature, humidity and surrounding oxygen environment are strictly controlled.

Ensure that microorganisms can grow and reproduce normally.

Before I knew it, it was dark outside.

Almost all the staff of the Agricultural Science Research Institute had left, leaving only one office with the lights on.

"Lao Zhang, what do you think?"

Xu Haodong asked.

Zhang Weimin hesitated and said, "Based on the fermentation process and production technology provided by Comrade Lin Kaifeng, if we want to maximize the nutritional value, we must degrade cellulose and hemicellulose. By breaking down these two substances that are difficult for livestock to digest, they can indeed be turned into animal feed."

"But to do this, we must always control the fermentation temperature and humidity, which is very difficult."

Hearing this, Xu Haodong began to ask Lin Kaifeng questions about the control of fermentation.

Dongshan Brigade is a production team, not a professional scientific research department.

First, there are no professional and technical personnel, and second, there are no relevant equipment.

How do they ensure that the bio-feed fermentation process goes smoothly?

Lin Kaifeng smiled bitterly and said, "To be honest with you two experts, the Dongshan Brigade has mastered the method of fermentation using straw, animal bones and earthworms."

"But the various problems in the fermentation process have never been solved scientifically."

"Fermented biological feed is an imperfect feed. It is not a big problem to use it to feed a small number of livestock."

“Once it involves large-scale breeding, scientists must be on hand to assist and guide, using professional instruments and equipment to control temperature, humidity, and oxygen to ensure that there are no deviations during the microbial reproduction process.”

Having said that, Lin Kaifeng glanced out the window.

"Two experts, it's getting late. Why don't we go out and find a state-owned restaurant and have a meal while we talk?"

"I brought a lot of food coupons and vegetable coupons with me this time. I will make sure that the experts will not be detained in restaurants and forced to wash dishes to pay off their debts."

"Hahaha……"

A joke made the atmosphere more relaxed.

Zhang Weimin smiled and said, "Come to my house for dinner. My wife passed away a few years ago, and my children are all working in other places."

"By the way, Comrade Lin Kaifeng, you haven't found a place to live yet, right? Why don't you stay at my house?"

"Excuse me, Expert Zhang."

Lin Kaifeng did not hesitate and agreed readily.

Zhang Weimin's home is only three kilometers away from the Chinese Academy of Agricultural Sciences.

The three of them talked as they walked, and soon arrived at Zhang's house.

Followed by.

Chen Kaifeng and Xu Haodong took their food coupons and tickets to buy vegetables and meat.

Zhang Weimin was responsible for lighting the stove.

During this trip to the provincial capital, Lin Kaifeng not only contacted experts from the Academy of Agricultural Sciences.

There are still a few important things to do.

If you contact the Agricultural Science Research Institute alone, one day will be enough.

In the remaining two days, Lin Kaifeng spent half a day visiting the Landrace pig breeders introduced by the Academy of Agricultural Sciences.

In the remaining time, I went to Jiangcheng Automobile Factory.

Making agricultural tricycles is just the beginning.

Lin Kaifeng has even greater ideals.

Build cars.

Jiangcheng is not only the provincial capital, but also a well-known automobile capital in China.

The first car in Longguo was born here.

As the Jiangcheng Automobile Factory rose from ground, various upstream and downstream manufacturers supporting it completed their construction one after another.

According to the planned economic model, the emergence of any large factory will be accompanied by a variety of supporting enterprises.

These supporting enterprises are auto parts factories, engine factories, vehicle tool factories, hardware factories, and machinery factories.

From spare parts and tools to complete vehicles, a series of industrial chain factories can be found in Jiangcheng.
