Phosphate fertilizer, as the name suggests, is a fertilizer with phosphorus as the main nutrient, and the full name is phosphorus fertilizer.

Rational application of phosphate fertilizer can increase crop yield, improve crop quality, accelerate the tillering of cereal crops and promote grain fullness. Promote the flowering and fruiting of cotton, melons, eggplant vegetables and fruit trees, and improve the fruiting rate; Increase sugar content in sugar beets, sugar cane, watermelon, etc.; The oil content of rapeseed.

If you use a meal to describe the three major chemical fertilizers, then nitrogen fertilizer is undoubtedly the staple food, while phosphate fertilizer is the dish on the table, and potassium fertilizer is the seasoning, and in modern agricultural production, all three are indispensable.

Among the modern fertilizers based on the three major elements of nitrogen, phosphorus and potassium, phosphate fertilizer is also the main product with the second largest yield and dosage.

In this regard, the Pingshan County Fertilizer Plant is no different from other fertilizer factories, and phosphate fertilizer is the second largest product in the factory.

However, Zhong Bai, who is well versed in professional knowledge, knows very well that phosphate fertilizer is precisely the most unlikely type of fertilizer among the three major fertilizers, and the county fertilizer factory has recently had problems with phosphate fertilizer, which makes him a little puzzled.

However, the materials did not explain the specific problems clearly, Zhong Bai felt that only by investigating and understanding could he know the specific situation.

This is not his whim, but after he accidentally heard the conversation about the quality problem of the fertilizer factory in the station restaurant, and today he heard Chu Juan faintly mention that the efficiency of the factory has declined because of the quality problem and the half-year bonus has not been paid, he feels that he should do something.

The road must be walked step by step, and things must be done one by one.

Although they have grand long-term goals, if they can't even solve the phosphate fertilizer quality accident in a small county fertilizer factory, then they can't talk about doing anything big for the country in the future.

In recent years, the composition of domestic phosphate fertilizers is almost fixed, basically chemical phosphate fertilizers, few natural phosphate fertilizers, and the components are mainly superphosphate.

The domestic production method is also mainly based on the acid method.

Phosphate rock is decomposed with sulfuric acid, phosphoric acid, nitric acid or hydrochloric acid, and the calcium in the phosphate rock is separated or fixed in the form of calcium salt.

In particular, the sulfuric acid method decomposes phosphate rock and separates calcium sulfate to obtain phosphoric acid. Phosphoric acid is the intermediate raw material for the production of high-concentration phosphate fertilizer and compound fertilizer, acid method is also known as wet method, phosphate fertilizer prepared by acid method, often collectively referred to as wet phosphate fertilizer, want to come to Pingshan County fertilizer plant is no exception.

The process is not complicated, there are not many technical processes in the intermediate links, and the only disadvantage is that it is more environmentally polluting, but in 1981, this was not the main problem.

Zhong Bai lay on the bed and thought about it for a long time but didn't figure out what the quality problem of this batch of phosphate fertilizer was, plus he was running around all day, he was a little tired at the moment, and gradually fell asleep on the first night after being reborn......

……

At seven o'clock in the morning, Zhong Bai, who was in a daze, was woken up by the loudspeaker sound in the factory.

The opening routine is still an uplifting song "Unity is Strength", which is also one of the favorite songs played in most factories in the early 80s, especially its rhythmic and strong collectivist lyrics, which is undoubtedly the best incentive for workers who have just come to work every day.

This was followed by the daily thunderous "newspaper summary", which was a rare source of television and radio in those days, and it was a rare channel for the vast majority of fertilizer factory workers to learn about the state and current affairs news at 3 o'clock every day.

Coupled with the sonorous voice of the announcer, Zhong Bai, who likes to sleep lazily, was inexplicably pulled up from the bed.

"Hmm...... It's finally a bit of the spirit of this era. ”

Anyway, today is the day of official registration, Zhong Bai changed into a clean shirt, wiped the ash on his leather shoes, and cleaned himself up in front of a separate "dressing mirror" in front of the big wardrobe.

It is said to be a "dressing mirror", but in fact, it is a simple large square mirror, without any complicated design, just like the Huaguo industry in this year, simple, primary, direct and practical.

Zhong Bai subconsciously came to the cafeteria to prepare for breakfast, but he saw the workers and workers in the queue holding colorful pieces of paper in their hands, and he reacted.

That's a meal ticket!

I haven't reported it yet, and I don't have a meal ticket, how can I eat here?

So Zhong Bai, who was helpless, had no choice but to walk out of the factory gate, pinching the only four cents in his arms, and preparing to eat breakfast first.

I didn't expect to meet Chu Juan at the gate of the factory.

"Hey, Zhong Bai, what are you dangling at the factory gate early in the morning?" When Chu Juan saw him, she raised her hand to greet him from afar.

Zhong Bai, who is a straight man of steel, immediately replied: "Didn't you also hang out at the gate of the factory early in the morning?" ”

Chu Juan approached and pouted: "What nonsense?" I'm going to go to the newly opened noodle restaurant to eat beef noodles, and I'm tired of eating in the cafeteria, otherwise I'm still sleeping. ”

I just didn't know where to go for breakfast, and when I heard this, Zhong Bai couldn't help but cheekily say, "What beef noodles?" Can you take me to try it? I'm in for a treat! ”

As soon as the sentence "I treat you" came out, Zhong Bai regretted his arrogance.

This is not Zhong Bai, a senior chief engineer with an annual salary of millions in his previous life, but Zhong Bai, who only has four cents on his body after being reborn!

But Chu Juan didn't know that Zhong Bai couldn't wait to take back the last three words, and immediately nodded happily: "Okay, I'll lead the way, you have a treat, why don't you agree to such a good thing?" ”

After speaking, Chu Juan took a step forward, found Zhong Bai standing still in a daze, turned his head and asked strangely, "Didn't you say to take you, why don't you leave?" ”

"That...... How much is a bowl of beef noodles? Zhong Bai scratched his head and asked a little embarrassed.

Don't be embarrassed if you don't have enough four cents at that time.

If you become a reborn person who can't afford to pay for food and runs away, it is estimated that there is no one before or since.

Chu Juan sneered: "Do you still think I'm going to knock you on a bamboo pole?" This shop is self-employed, not expensive, a dime and a half a bowl! It's a bit far, so we'll have to walk for a while. ”

"It's okay to have a dime." Zhong Bai was relieved when he heard this, and immediately followed Chu Juan's footsteps.

In 81, in addition to the state-run restaurants that could not be beaten, there were already self-employed people who made breakfast and sold it on the streets.

Although self-employed was originally a derogatory term, in the early 80s, it was basically synonymous with unemployed youths and labor prisoners, and was incompatible with mainstream society, but it was these people who caught up with the first wave of China's reform and distribution, enriched China's economic component dominated by the public-owned economy, and laid the groundwork for the future market economy.

Hearing Chu Juan mention the word "self-employed", there was no contempt, Zhong Bai secretly felt that this little girl had done a good job in emancipating her mind.

The county fertilizer factory is on the outskirts of the city, in fact, it is still a little far from the county seat, but he is used to the scale of the metropolis in his previous life, even if he walks for twenty minutes, Zhong Bai does not feel that it is too far.

The two of them arrived at the door of a newly opened beef noodle restaurant, where there were already six or seven diners seated.

After Chu Juan sat down, she hurriedly introduced: "It's this fresh wind beef noodle, it tastes very good, their beef noodle soup is very fresh, you can taste it." ”
