My plug-in is not that strong

Chapter 14 Iron Humate
Back at the institute, everyone scattered back to their offices.

Song Yu sat back in front of her desktop computer.

Because it is almost 01:30, even if I take a nap, I can only rest for half an hour.And he is in good spirits now, and he didn't want to rest, so he didn't put the recliner.

Staring at the desktop computer equipped in the research group, Song Yu was stunned for a while.

Recalling that half a year ago, Song Yu was about to finish his master's course, and full of fighting spirit, he asked Mr. Zhang what he would like to do in the future.

Mr. Zhang, a busy man, only asked him to make humic acid fertilizers, such as potassium humate and sodium.Song Yu, an interdisciplinary candidate from environmental engineering, didn't understand what Teacher Zhang was saying.

Of course, he knows about humic acid, because he also learned it in the "Advanced Soil Science" in the culture class, which is the general term for the part of the organic matter in the soil.It is an organic macromolecular substance that has been decomposed by animals, plants and even microbial residues for many years and finally remains in the soil. It is rich in aromatic rings and alicyclic rings with various functional groups.It can be seen from the source that humic acid exists not only in soil, but more in peat, lignite and weathered coal.

In short, from a non-rigorous point of view, the difference between sand and soil is that the latter contains humic acid.

Moreover, humic acid can not only be used in soil-related agriculture, forestry, and animal husbandry, but also in various fields such as petroleum, chemical industry, building materials, medicine and health, and environmental protection.Humic acid is highly respected especially for the construction of ecological agriculture, pollution-free agricultural production, green food, pollution-free environmental protection, etc. that are now advocated.

As for potassium humate or sodium humate, Song Yu is not clear.So he immediately asked Mr. Zhang, and Mr. Zhao explained that it could be extracted by chemical reagents.

Although Song Yu didn't understand, he felt that he had a direction to check, so he didn't have the nerve to ask further.

Of course, even if he asked, the teacher would let him check the literature by himself.After all, Mr. Zhang is very busy. All the teachers, classmates and project hires of the whole research group have to test him to support the project.

In the next six months, Song Yu hardly saw Teacher Zhang. He arranged for himself to attend classes, go home for the winter vacation to celebrate the New Year, study for the start of the semester, and then perfect the plan until now.

Almost all the documents on humic acid that Song Yu found in the library of the Institute are from the 80s of the last century.The literature collected on the Internet is also the most in the last century, but in the past 20 years, there have been relatively few researches on humic acid in agriculture.It may be that the enthusiasm for research has waned.

In the literature reviewed, humic acid fertilizers are mainly potassium humate, sodium, and ammonium humate, and ammonium humate is better for improving saline-alkali soil. However, this research was done 50 years ago. There is nothing new.

After Song Yu came back to his senses, he clicked on his perfect PPT about the experimental plan.Looking at the introduction about humic acid and humic acid fertilizer written by himself above, he has already found the research direction he wants to study - iron humate.

Potassium humate, which is extracted with potassium hydroxide and replaced with ferrous sulfate, contains the organic matter required by the soil, and is also a kind of iron and potassium fertilizer.The raw material used is the peat material in Mr. Zhang's project.

Moreover, after consulting the information, iron humate can not only be used as a fertilizer, but also a structural modifier of saline-alkali soil.The key is that there are very few researchers at present, and there are great prospects for development.

Song Yu's research background, research significance, theoretical basis, research content, technical roadmap and experimental design are all displayed on the PPT.

As far as Song Yu is concerned, the research on iron humate can be applied to the rapid improvement of saline-alkali soil, eliminating salinity, reducing alkalinity, improving soil structure and increasing the fertility of saline-alkali soil.No matter how good the effect is, it is expected to be applied to any soil with poor structure, which will significantly improve the quality and quantity of the country's cultivated land, and will make a huge contribution to food security.

After sorting out the PPT for a while, Song Yu received a reply from her senior sister, saying that she had already met her mentor, and she would come to find Song Yu later.

Thinking about it, Mr. Zhang is a person who sees the beginning and the end every day. It would be nice if he could talk with Cheng Jia for half an hour, and it wouldn't be too long.

When Cheng Jia arrived, the two went to the conference room on the third floor to discuss the plan.

……

After Song Yu finished talking about the 20 or so PPTs he had made, Cheng Jia thought for a while and asked, "Song Yu, do you have any plans to continue your PhD?"

Song Yu was a little puzzled. Could it be that the plan is so good that even doctors can use it?
Of course, Song Yu was not so confident yet, so he replied honestly: "Think about it. If you want to have a stable job in the future, besides taking the civil service exam, going to college is the best choice. And if you want to go to college, at least one Doctoral degree."

Cheng Jia saw that Song Yu wanted to study for a Ph.D., nodded and said, "Yes, so I want you to try to transfer from a master's degree to a Ph.D. degree next year, and directly transfer to our supervisor's Ph.D."

"But, senior sister, won't you graduate next year? Don't you take the Ph.D. exam? If you transfer from master's degree to Ph.D., you won't be able to take the exam if I transfer." Song Yu asked.

Cheng Jia said indifferently: "I, you don't have to worry. I'm not that interested in scientific research. Besides, you are a boy. If you want to stay and study for a doctorate, Teacher Zhang will definitely agree, so he will agree to you first when the time comes. The quota naturally does not exist. There is no competition with me or anything. Besides, I don’t like our tutor’s stocking status very much. If I want to take the exam, I will also be admitted to other research groups. I don’t have to be embarrassed to go to other research groups.”

Hearing what the senior sister said, Song Yu felt relieved, and he asked suspiciously: "Why did the senior sister ask me if I want to study for a doctoral degree?"

Cheng Jia: "It's just that your plan is well organized and the research is very meaningful. But if you want to study it in detail, two years of your master's degree are not enough. Of course, the content of your plan still needs to be added."

After Song Yu heard it, she was moved.He was going to take the postgraduate entrance examination. On the one hand, he really wanted to find a stable job in the future. On the other hand, he really liked doing scientific research.Now, since the design of his own plan is not bad, if he becomes a blogger, he will have four years to use, and he can make his own set of things.

The key point is that Song Yu has not forgotten the "barrier" and "30 years later" that Xiaoye said.I always feel that something big will happen in the future, and I need to do something.

If the iron humate studied can really be used as an amendment for any barrier soil, it will have a positive restoration effect on future cultivated land, forest land, and even deserts.When the soil is good, food, vegetation coverage, greening, greenhouse gases, etc. will be solved accordingly.

Thinking about it, there is a sense of mission gathered in Song Yu, which makes him full of fighting spirit for the future of the earth and his own future.

"Then senior sister, what else should I add?" Song Yu asked energetically.

Cheng Jia smiled slightly and said, "Saline-alkali tolerant microorganisms."
