Rebirth 1975: Tore up the call-back order at the beginning

Three days later!

On the gravel road from Yunshan County to Ning City, a brand new jeep sped fast, splashing dust.

In addition to Liu Yunlong and Zhou Yang, there were elder brother Zhou Ping, sister-in-law Tana and U Rina in the back seat.

Today, they are going to Fengxian Fertilizer Factory to visit their father.

By the way, Zhou Yang also ordered a batch of fertilizer from the fertilizer factory in Feng County for the village.

But before that, they had to send Uzhina to Ningshi Railway Station. The girl was going back to Qingcheng today.

After discussion, Uzhina has decided to come to Babaoliang Village to be a teacher, because of love!

However, this is a major event in life after all, and it needs to be discussed with family members, and at the same time, you have to go back to school to go through some procedures.

Because of this, Uzhina, who was planning to stay in the village for a while, decided to return to Qingcheng ahead of schedule!

After sending Uzhina to the train station and buying a ticket, Zhou Yang asked her to wait at the station by herself.

Then everyone continued on their way to the fertilizer factory.

At the fertilizer factory, Zhou Yawen didn't know that his two sons and a daughter-in-law were already on their way to visit him.

At this time, he was nervously observing the operation of the equipment in the production workshop.

After more than half a year of research, they have figured out the new technology of the phosphate fertilizer, and the high-concentration phosphate compound fertilizer has entered the stage of trial production.

If there is no problem with the test production and the product quality is qualified, then they can completely understand the high-concentration phosphate compound fertilizer technology from the beautiful country, and they can produce this high-concentration phosphate fertilizer on a large scale.

With the equipment slowly shutting down, the technicians took part of the produced bulk products with excitement.

Zhou Yawen took the off-white powdered fertilizer that was still hot to the touch, looked at it carefully, and smelled it again.

"The sour taste is very strong, it's phosphate fertilizer!" Zhou Yawen confirmed.

"Old Zhou, has the concentration reached the standard?" Zhang Yuhe, director of the fertilizer factory, asked a little excitedly.

"I can't see this, it must be tested!"

"Then what are you waiting for, test it quickly!"

Immediately afterwards, everyone rushed to the laboratory with the produced samples.

After returning to the laboratory, Zhou Yawen personally operated to test the phosphorus content of these samples.

During Zhou Yawen's examination, dozens of people outside the laboratory looked at him nervously, and everyone including Zhang Yuhe was very disturbed.

You must know that for this set of phosphate fertilizer production technology, they not only spent a huge sum of more than 5 yuan, but also spent more than half a year researching it.

At present, the product has finally been trial-produced, but the quality is still uncertain, so everyone's eyes are tightly focused on Zhou Yawen, waiting for his final "judgment".

If the phosphate fertilizer produced does not contain enough phosphorus, it will be a big loss.

Suddenly, Zhou Yawen in the laboratory shouted excitedly: "68...68...68%!"

Hearing his words, everyone including Director Zhang was stunned, and then cheers broke out.

According to industry standards, according to the level of available phosphorus contained in phosphate fertilizer, it can be divided into three categories: low, medium and high:

When P2O5<20%, it is a low-concentration phosphate fertilizer!

Between 60%<P2O5>30% is a medium-concentration phosphate fertilizer.

Only when P2O5>60%, it can be called high-concentration phosphate fertilizer.

It is not impossible to produce phosphate fertilizers in China. In fact, at the beginning of the founding of the People's Republic of China, we realized that agriculture is the foundation of the country, so we should not pay attention to the development of the fertilizer chemical industry.

So as early as the first five-year plan period (1953-1957), a series of development plans were formulated, and the first phosphate fertilizer plant was established in Jinling.

But at that time, our phosphate fertilizer production was restricted by technology, capital and resources, and the development was very slow. In the domestic phosphate fertilizer industry, low-concentration phosphorus compound fertilizers such as superphosphate accounted for 95% of the total phosphate fertilizer output.

We can hardly produce advanced high-concentration phosphate fertilizers that are of great significance to agricultural production. Even if we can produce some, the cost is extremely high, and large-scale production is simply impossible.

Therefore, the whole country urgently needs an advanced high-concentration phosphate fertilizer technology that can be produced on a large scale.

And the technology obtained from the technicians of the beautiful country gave everyone hope, which is why Zhang Yuhe took such a big risk and traded with the technicians of the beautiful country at a high price.

Although the phosphorus content of 68% can only be considered as a high-concentration phosphorus compound fertilizer, as long as it exceeds the passing line of 60%, it can be regarded as a real high-concentration phosphorus compound fertilizer.

Most importantly, today is just trial production.

The ratio of raw materials can be adjusted, and the phosphorus content of the product can be gradually increased.

In other words, they succeeded, and they finally produced their own high-concentration phosphorus compound fertilizer!

After the cheers, Zhang Yuhe excitedly grabbed Zhou Yawen's hand and said, "Professor Zhou, thank you. On behalf of the employees of the whole factory, the people of the whole province thank you!"

"Director Zhang, you are welcome. This is the result of everyone's joint efforts. I am also very happy to succeed!" Zhou Yawen also said a little excitedly.

"Hahaha, I'm so happy today. Immediately notify the cafeteria to give all the staff extra meals at noon. Hurry up!" Zhang Yuhe said excitedly.

"it is good!"

Shocking cheers broke out in the laboratory again...

While everyone was cheering, a young man hurried in and said, "Professor Zhou, where is Professor Zhou?"

Hearing the voice, Zhou Yawen immediately said, "What's the matter here?"

"Professor Zhou, someone is looking for you at the gate!"

"Looking for me, who is it?"

"It's your son!"

Hearing this, Zhou Yawen immediately said: "Alright, alright, I'll go over and sign the contract!"

The chemical fertilizer factory is a key unit. No matter whose relatives come, they must personally sign at the gate to lead them into the factory, and they must be responsible for any accidents.

As soon as the words fell, Zhang Yuhe said with a smile: "Professor Zhou, wait, I'll go with you. I haven't seen Comrade Zhou Yang for a while, so I just chat with him!"

"Row!"

Afterwards, Zhou Yawen confessed to several young students under his command, and then left the laboratory with Zhang Yuhe.

........

Fertilizer factory, the gate!

The two brothers of the Zhou family were chatting, while Tana was staring at the sheep on the distant mountain ridge in a daze!

"Xiao Yang, this is the county fertilizer factory you mentioned, isn't it too big?"

It was the first time for Zhou Ping to come to Feng County Chemical Fertilizer Factory. Looking at the huge factory in front of him, he couldn't hide the shock in his eyes.

He just heard that his father was doing scientific research in a chemical fertilizer factory, and he temporarily gave up the opportunity to return to the capital because of this factory, and he was somewhat puzzled.

After all, in his opinion, a small county-level chemical fertilizer factory is not worth doing for his father.

But after actually coming to the chemical fertilizer factory, I was surprised to find that I seemed to be misled by the name of the factory.

Zhou Yang smiled and said, "The Hexian Fertilizer Factory and Fengxian Fertilizer Factory are the largest fertilizer factories in the entire Saibei Province, with a designed production capacity of one million tons."

"Besides, he is a serious provincial management unit, and the level is equal to that of Fengxian county government!"

Zhou Ping smiled and said: "So that's the case, I thought it was an ordinary small fertilizer factory!"

At this time, Tana asked curiously: "Brother, what is the father-in-law responsible for here?"

"The laboratory is responsible for the research and development of new technologies!"

Just as he was talking, Zhou Yang suddenly saw a few people coming out of the factory in a hurry.

Taking a closer look, it was his father Zhou Yawen who was walking in the front, and next to him was the chief executive of the fertilizer factory, Director Zhang.

"Dad, they are here!"

At that moment, Zhou Yang stopped talking with his elder brother, and immediately brought his elder brother to meet him.
