Agricultural giant since 1983

Chapter 111
"Mr. Jiao has worked hard during this period. Our factory can produce products of far better quality than before, thanks to Mr. Jiao!" Li Lei thanked.

"It was a bit tiring during this time, but I also gained a lot. I used to learn the theory at school. This time I practiced it for the first time, only to realize that the theory is the theory after all, and it takes a lot of effort to implement it!" A smile appeared on Jiao Gaoliang's face as he spoke.

"Professor Tang called the factory yesterday and told me the good news. The paper I wrote some time ago based on the new equipment in the factory has passed the preliminary review of the magazine "Phosphate and Compound Fertilizer". It can be officially published! Professor Tang said that as soon as the paper is published, my graduation project will be over!"

"Congratulations. With the thesis, it will be much more convenient for you, Mr. Jiao, to evaluate your title after staying in school; but "Phosphate Fertilizer and Compound Fertilizer"? Is there such a journal?" Li Lei asked intentionally.

In fact, he is quite familiar with this magazine. It is an authoritative journal in the field of fertilizers in China. It is only calculated according to time. When Li Lei was still studying at Zhongyuan Agricultural College, the journal had not yet been born.

"It was organized by Professor Tang and several other old professors in collaboration with Zhongyuan University and the Phosphate Fertilizer Industry Association. Now the procedures have been completed, and the first issue is going to be published after the next semester starts. Now we are collecting articles. I just happened to be lucky! Several types of equipment are rare in China, and there are even no related papers! It can be regarded as filling a gap in China." Jiao Gaoliang said reservedly.

Nowadays, domestic academic circles are eager for all information from abroad. If that unit has the money to introduce new equipment, it can publish a paper just by translating the manual. After the trial, it will be another paper to write down the impressions. If there are any problems in the middle, then solve Yes, there is one more!
After Jiao Gaoliang's serious research, he put it into practice and made a summary. The papers he wrote were definitely of high quality, and publication was not a problem at all.

"As for the evaluation of professional titles, there are indeed requirements for papers, but this is not what I value!" Jiao Gaoliang now also wants to share his joy with others. Some things are inconvenient to say to classmates and colleagues, but it is quite appropriate to tell Li Lei. So he said a little more.

"Our school has a few places to go abroad to study for a doctorate at public expense this year. The school has put forward requirements. Not only must you have good academic performance, but you must also have certain achievements in academics. Once this paper is published, my score will increase a lot. Luckily. If it’s good, maybe you can go to the United States to study for a doctorate!”

"If you come back from a doctorate in the United States, it will be great. Maybe Central Plains University can't accommodate your big Buddha! Isn't China Agricultural University and Northwest Agriculture and Forestry vying for it?" Li Lei was even more puzzled.

Given the current domestic environment, if Jiao Gaoliang returns from his Ph.D., he will definitely be entrusted with a heavy responsibility.Could it be that he didn't come back after studying abroad?

"Hey, look at my brain. Since I went to study in the United States, I should find a way to stay. China Agricultural University and Northwest Agriculture and Forestry are considered good in China, but they are far behind Cornell, University of California, and University of Wisconsin. !” Li Lei asked tentatively.

In the future global agricultural university rankings, China Agricultural University will be able to squeeze into the top ten, and the rankings of the University of California, Davis, Cornell University, University of California, Berkeley, and the University of Wisconsin will be even higher.

Wageningen University in the Netherlands has long been ranked first in the world, in addition to the Swedish University of Agricultural Sciences, the Paris Tech Agricultural Institute, the Federal Institute of Technology in Zurich and the University of Reading in the UK.

"The United States is definitely good, but according to the regulations, you have to come back to study abroad at public expense, and my parents have suffered all their lives. Now that I have finished my studies, I have to take them to the city for a few days to live a good life, right?"

From what he said, it seems that he has no intention of staying in the United States, but it is not clear, after all, it is one thing before going to the United States, and another thing after arriving in the United States.

As long as you are willing to come back, there is still hope. Even if the school refuses to release people at that time, can you still engage in cooperation, so Li Lei began to draw cakes, "Hey, the gap between the domestic phosphate fertilizer industry and foreign countries is really too big. The equipment we have introduced is considered advanced domestically, but it has long since been eliminated abroad.”

Anyone who has studied biology knows that nitrogen, phosphorus, and potassium are three elements necessary for plant growth, and the application of phosphorus in agricultural fertilizers dates back to 1840.

In that year, Liebig published "The Role of Organic Chemistry in Agriculture and Physiology", which scientifically demonstrated the problem of soil fertility. His research showed that in addition to carbon, hydrogen, oxygen, and nitrogen, plants also have Sulfur, potassium, phosphorus, calcium, iron, manganese, silicon and many other elements are required.

The source for plants to absorb all the above-mentioned elements is the soil. In order not to cause the soil to gradually become poor, which will eventually lead to a decline in crop yields, artificial fertilizers are required.

Liebig also pointed out based on his research that not only potassium fertilizers, but also phosphorus fertilizers are of special significance for improving soil fertility.

In 1842, Lauvis established a superphosphate factory with bone meal and sulfuric acid production, which was the beginning of the chemical fertilizer industry.

In 1843, Britain and France successively used coprolites containing tricalcium phosphate left over from ancient times to replace bone meal to produce superphosphate fertilizer.

In 1856, Liebig proposed to use sulfuric acid to treat the natural phosphate rock, which is mainly composed of tricalcium phosphate, so that the tricalcium phosphate in the mine can be converted into water-soluble monocalcium phosphate.

In 1884, the German Heyerman inspected the slag discarded by the Thomas steelmaking method and found that it contained phosphorus components that were easily absorbed by crops. In 1889, the total output of Thomas' phosphate fertilizer in Europe reached 70 tons.

With the development of phosphate fertilizer production, various high-concentration phosphate fertilizers, such as rich superphosphate, heavy superphosphate, dicalcium phosphate, etc., have also been successfully researched.

The development of China's phosphate fertilizer industry is 100 years behind that of foreign countries. It was not until the 50s that four small superphosphate plants were built during the First Five-Year Plan.

The first wet heavy superphosphate production line was built in 1982. As for the production technology of monoammonium phosphate, diammonium phosphate, ammonium polyphosphate and other compound fertilizers, it is also far behind foreign countries.

As soon as this topic was discussed, Jiao Gaoliang became extremely excited. He had also read all foreign journals and knew the gap in this regard.

"I want to go out early now, learn all the skills of foreigners, and then let our fertilizer factory produce better fertilizer!"

"Research costs money. Given the current situation in our country, even if you come back, you probably won't be able to get much funding, right? But it doesn't matter if the state doesn't allocate funds. I've already figured it out. In the future, the fertilizer plant will get [-]% of the money every year." Ten of the income to do research!"

"If you are willing to come, I will give you 20 yuan a year!" Li Lei began to draw cakes again.
