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

"You have offended so many people for me over the years. Now you are in trouble. How can I, as your son-in-law, ignore it?"

"I brought the bones back to help you solve the problem."

"The bones can be used as pig feed to feed a few piglets."

"It can be used as pig feed?!"

Lu Dayong almost spit out the wine he had just drunk.

It wasn't even completely dark yet, why did Lin Kaifeng start talking nonsense?

Lin Kaifeng said seriously: "Dad, please listen to me. Bones alone cannot be used as pig feed. What I mean is that bones are an additive to pig feed. In addition to bones, we also need wheat straw, corn stalks, rice straw, bran and other things."

"We have just finished the autumn harvest and there is a lot of straw in the fields, which can all be used to make pig feed."

Lu Dayong, who had been doing farm work for half his life, couldn't believe his ears.

Straw and weeds that can only be used for burning can actually be used to feed pigs?

"Not only can they feed pigs, but pigs that eat these feeds are fat and strong, and have a high meat yield."

"Dad, if you don't believe in science, you should at least believe me. I really want to solve this problem for you."

"Think about it, if the feed problem is solved, we will have more opportunities for sideline businesses. We won't have to live a hard life anymore. We can raise pigs or ducks if we want. Without the worry of feed, we can raise anything."

Lin Kaifeng is right about the direction of developing a side business.

What is wrong is to give blind orders without considering the actual situation.

"Why does it sound so mysterious to me..."

Lu Dayong frowned.

Can you feed pigs by mixing various straw things together?

Can it be used as feed?

"Dad, how about this? Let me take care of the pig feed. If the pigs die, I will use my connections in the county to get a few big fat pigs to make up for the shortfall."

After he finished speaking, Lin Kaifeng moved and took two books from the kang.

"Dad, if I finish translating these two books, I can earn at least one or two hundred yuan. One or two hundred yuan is enough to buy two or three big fat pigs and hand them over to the commune."

"Just promise Kaifeng and let him try."

At some point, Lu Xiuxiu appeared in the room.

Help Lin Kaifeng to persuade Lu Dayong and ask his father to give Lin Kaifeng a chance to perform.

"Okay, then you try it first. If something goes wrong, Dad will bear the responsibility with you."

Regardless of whether the matter succeeds or not, Lu Dayong is already very satisfied that Lin Kaifeng has this intention.

prior to.

Lin Kaifeng doesn't care about anything.

If a bottle at home fell over, Lin Kaifeng wouldn’t even look at it.

Now I can earn money and am willing to share the worries of my father-in-law.

What else does Lu Dayong have to say?

Take a step back.

For the sake of his daughter, he was also willing to give Lin Kaifeng a chance to perform.

After seeing Lu Dayong off, Lin Kaifeng became full of energy.

Convincing Lu Dayong is half the battle.

There is nothing difficult about making biological feed.

The biological feed production method that will be commonplace in the future is not considered high-tech at present.

It's nothing more than fermentation and stirring.

There are no machines in the countryside, so Lin Kaifeng put aside the machines and adopted a fully manual production method.

Bones were ground into powder and various straws were collected by human labor.

The straw is pulverized and fermented with purified water.

As for the leavening agent, it is not a big problem.

Lin Kaifeng is a idler in the Dongshan Brigade.

Not much else, but time.

In the past few years, Lin Kaifeng almost grew up at home.

Apart from occasionally going out to hang out at the educated youth camp, the rest of the time was spent lying at home reading books and newspapers.

Just sleep.

Early this morning, Lin Kaifeng finished his meal early and appeared in the fields.

The team members stopped their work in twos and threes as if they were seeing something new.

Looking at Lin Kaifeng standing by the field and talking to his brother-in-law Lu Kangmei.

Lu Kangmei said in surprise: "Is it possible?"

"Brother, Dad has agreed, so what's the problem? Find a few teammates I have good relationships with and help me with the work.

Thinking of this, Lin Kaifeng took out a few dollars

"Don't let them work for free. Pay fifty cents each."

"Take the money back. As soon as you make a little money, you start spending lavishly."

Lu Kangmei said unhappily: "It is only natural for the elder brother-in-law to help his brother-in-law."

"If you give me money, I won't care."

"Wait, I'll find someone right away."

Lu Dayong agreed to let Lin Kaifeng be responsible for the pig feed issue, and Lu Kangmei had nothing to say.

Soon, Lu Kangmei found a few familiar team members.

Everyone came to the Lin family. Lin Kaifeng pointed at the bones all over the ground and asked everyone to help move them to the open space behind the village.

Set up the wood and put the bones on the fire.

The original plan was to evaporate all the moisture in the bones by drying them in the sun.

After thinking about it last night, Lin Kaifeng remembered that bones contain not only water but also a lot of salt.

Drying in the sun cannot decompose the salt.

The best way is to evaporate the salt by steaming it.

However, steaming is very time-consuming. It will take more than a few days to steam hundreds of kilograms of bones.

You also need to prepare a large number of steamers.

Burning it in the fire is not only fast, but also saves trouble.

Not a moment.

Several fires were burning in the wasteland behind the village.

Lin Kaifeng directed everyone to throw the bones into the fire one by one.

The salt in the bones is removed by roasting them over fire.

After the desalting step is completed, the bones will be air-dried again.

Wait until all the moisture inside is dried up, then you can proceed to the last step.

Beating, grinding.

Use a blunt object to break the bones into pieces and grind them into a fine powder using a roller.

Without machines, you must be prepared to spend time, effort and time.

Fortunately.

After the autumn harvest, many of the brigade's laborers were idle.

It's no problem to find someone to help with the work.

"How dare you set fire!!!"

An angry shout was heard.

Lu Kangmei looked back with a cold expression on his face.

"I was wondering who it was that was so impressive. It turned out to be Captain Zhao."

"You are such a rare visitor. When did you come back?"

Lin Kaifeng's expression was even uglier than Lu Kangmei's.

The number one scumbag of Dongshan Brigade, captain Zhao Weiguo who went out to study, is back.

"Boss Lu, do you know how to talk? I am originally from the Dongshan Brigade. What do you mean by rare guest?"

Zhao Weiguo asked Lu Kangmei to go with him.

We have repeatedly been reminded to pay attention to fire prevention.

As the son of the brigade secretary, Lu Kangmei openly fanned the flames.

It is obvious that they are going against their superiors.

Relying on his father being the brigade secretary, Lu Kangmei is simply lawless!

"Captain Zhao, don't rush to accuse others as soon as you get back. My father and I won't be intimidated by you."

Lu Kangmei sneered and said, "We are lighting a fire to do serious business. If you have nothing to do, go back."

"It's going to be dark soon, be careful walking on the road at night, or someone will hit you with a black brick."

As soon as these words came out, everyone laughed.

There were at least eighty people in the team who wanted to deal with Zhao Weiguo.

pity.

In the entire brigade, only the men from the Lu family can deal with him.

Others don't have the courage.
