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

In the Zhou family's old house, the chat between father and son is still going on!

Hearing his son asking about his work, Zhou Yawen frowned.

Speaking of his work in the Northwest, he was really not going well.

"It's hard to say. At present, it should not come back in a short time!"

Hearing this, Zhou Yang frowned.

He knew that his father went to work in the northwest region last year at the request of the Ministry of Chemical Industry, and the time at Beijing University was really chaotic. In order to get out of that whirlpool, his father left the capital.

However, Zhou Yang knew very little about what work they would be transferred to the northwest region, and what tasks the Ministry of Chemical Industry had arranged for them.

"Dad, may I ask what project you mainly research in Northwest?"

Afterwards, Zhou Yang said again: "Of course, if you have confidentiality requirements, you don't have to say it!"

Zhou Yang is also engaged in scientific research, so he naturally knows that some scientific research tasks have a high level of confidentiality, and he does not inform his parents, wife and children.

Therefore, he didn't want to embarrass his father either!

Zhou Yawen smiled and said: "It's not a secret project, it's just studying potash fertilizer over there!"

Hearing the word "potassium fertilizer", Zhou Yang nodded, and it was exactly as he thought.

In fact, Zhou Yang thought about this when his father was transferred to the Northwest. At that time, he thought that the Ministry of Chemical Industry transferred his father to the Northwest to study chemical fertilizers, and it was probably potash fertilizers.

It's not that Zhou Yang has the ability to predict, but it's inferred from the combination of his father's identity and the current national conditions.

Among the three major fertilizers needed in agriculture, nitrogen and phosphorus fertilizers have been solved in China at present, and only potassium fertilizers are still in their infancy.

Moreover, compared with nitrogen and phosphorus fertilizers, potassium fertilizers are more important, because potassium is an essential quality element for plant growth and development, and it can make crops grow stronger.

At the same time, it can enhance the stress resistance of crops, such as cold resistance, drought resistance, salt resistance, lodging resistance, disease resistance, etc., enhance the ability of crops to resist and endure harsh external environments, and can significantly improve the stable and high-yield performance of crops.

At present, the only potassium salt mine discovered in China is in the northwest region, and my father, a chemical expert, was transferred there, most likely to study potash fertilizers.

"See what you mean, isn't the project progressing smoothly?" Zhou Yang asked again.

"It was very difficult. The task we received was to improve the production process of potash fertilizer, but when we came to the potash mine in the Qarhan area, we found that the task was far more difficult than we imagined!"

Then my father said again: "Although the reserves of potash mines there are not small and have reached the standard of large-scale salt mines, the content of potassium salts in the brine is not high, and the difficulty of mining is much higher than that of foreign solid salt mines. The development and utilization of salt mines has caused considerable difficulty!"

"The most important thing is that our technology is too backward and the basic conditions are too poor, which greatly limits the production of potash fertilizer. We have studied for more than half a year, but we have not achieved decent results!"

Hearing his father's words, Zhou Yang also fell silent.

The present situation of domestic potash fertilizer production is indeed not very optimistic, with low output, low purity and poor effect.

Coupled with the rapid increase in the population of our country, more and more food is needed, and the demand for potassium fertilizer is also increasing.

At present, the self-produced potash fertilizers in the country can no longer meet the needs of domestic grain production, and they have to import a large amount of potash fertilizers from abroad every year.

It can be said that the serious shortage of resources such as potassium fertilizer has become a major obstacle to the current economic development.

Thinking of this, Zhou Yang immediately said: "Dad, I think the main cause of the current predicament is the lack of resources and backward technology. The Ministry of Chemical Industry wants to make breakthroughs in technology and improve the utilization rate of potash mines. I think we can think of another way from the perspective of potash mine resources!"

Zhou Yawen sighed and said: "The higher authorities don't know what you said, but it's not easy to find new potash mines. We are recognized as a potassium-poor country!"

Poor oil and potassium deficiency has always been a major problem for us for a long time. Even at the beginning of the founding of the People's Republic of China, some foreign experts asserted that my country is a potassium-poor country with no potassium resources to follow.

Although as early as the "First Five-Year Plan" period, my country began to look for potassium mineralization prediction work, and finally discovered the existence of potassium salt deposits in the Qarhan area of ​​the Qaidam Basin, which officially opened the curtain of potassium salt mining in my country .

But so far, the number of potash deposits found is still very rare, and they are mainly concentrated in the Qaidam Basin, and no potash deposits have been found in other areas for the time being.

Just when Zhou Yawen was sighing, Zhou Yang said suddenly: "Who said we are a potassium-poor country, there must be potash mines in our country?"

Hearing his son's words, Zhou Yawen was taken aback for a moment, then shook his head and said: "If there is any, those comrades from the prospecting team would have found it long ago. Why are they controlled by others like now!"

"That's why they didn't find the right place!"

Then Zhou Yang said again: "my country's potassium resources are not abundant, but I don't agree with the statement of "poor potassium"."

"Hehe, this has been a common view for many years, and it's useless if you don't agree with it, unless you can find a super-large potash mine!" Zhou Yawen said with a smile.

"If you let me look for it, I will definitely find it!" Zhou Yang said confidently.

Seeing his son's affirmation, Zhou Yawen couldn't help but get serious, and immediately asked, "Can you really find it?"

"I can find it!"

"where is it?"

"Lop Nur!"

"Lop Nur, Lop Nur in Western Xinjiang?"

"Yes, Lop Nur was the center of water accumulation in the Tarim Basin in ancient times, and rivers formed by melting snow in the nearby Kunlun Mountains and Tianshan Mountains would all converge into the low-lying terrain of Lop Nur to form lakes. These flowing waters contain potassium ions, which are deposited to form potash mines."

Then Zhou Yang continued: "According to geological theory, Lop Nur has the conditions to form potash deposits, so as long as you look for them, you will definitely find them!"

Zhou Yang's tone was very firm. After all, Lop Nur has a potash mine, which is open to future generations.

Coupled with the promotion and exaggeration of the movie "Lop Nur of Life and Death", even people who have not studied geology know this.

However, the country's attention is still in the Qaidam Basin. It was not until the 80s that it began to focus on Lop Nur, and finally discovered potassium nitrate salt deposits in the Tuha Basin in the northern part of Lop Nur during the "Eighth Five-Year Plan".

After listening to his son's words, Zhou Yawen was stunned for a while, but still shook his head.

"You are just your own guess, and there is no basis for it. What's more, Lop Nur has long since dried up. Looking for potash mines from that dead place is tantamount to finding a needle in a haystack!"

Although Zhou Yawen also felt that what his son said was reasonable, he still felt that it was completely impossible to find potash mines in Lop Nur.

What's more, where there are thousands of miles of desolation, even if you find it, you can't mine it.

Instead of wasting time on this matter, it is better to spend time and energy on technological breakthroughs.

Zhou Yang didn't explain either, his father is not a geologist after all, so it's useless to talk to him about it.

But he has already made up his mind that he must take this matter seriously and help the country find potash mines.

Not just to prove ourselves to my father, but more importantly, potash mines are really important to us.

However, as my father said, it is really difficult to find potash mines in Lop Nur, which can be seen from the movie "Life and Death Lop Nur".

Therefore, it is necessary to plan carefully how to do this matter.

For a moment, Zhou Yang fell into deep thought!
