Xu Shiyan has to take classes and is also responsible for the compilation of the book "New Technology for Ginseng Cultivation", which is even busier now.

In addition to classes and meals every day, most of the time is spent in the library, or in the dormitory.

Several people in the same dormitory are from neighboring counties, although they are not as famous as Fusong planting ginseng, but there are also plantings, and everyone understands it.

So everyone is also very interested in what Xu Shiyan wants to write, and they often get together to discuss it.

Later, I didn't know what was going on, even their mentor knew.

I also specifically asked Xu Shiyan to go over, and was particularly concerned about the compilation process of this book, saying that he would wait for the manuscript to come out and show it to the school first.

In this regard, Xu Shiyan did not object, one person counts the short, and the two count the long, so they should brainstorm.

These professors of Agricultural University are all really talented and learned, and being able to get their corrections and opinions is of great benefit to both this book and Xu Shiyan.

Just taking the opportunity, Xu Shiyan put forward the idea of ginseng biological compound fertilizer and biotechnology foliar fertilizer.

"Teacher, this is a little bit of my idea, which is to use compound microbial bacteria, such as 5406 strains.

Coupled with compound amino acids, organic main materials, auxiliary materials, etc., the use of biological fermentation technology composting, should be better than the previous ginseng fertilizer. ”

This is an idea put forward by Xu Shiyan after studying at Agricultural University, after reading countless related books and verifying various documents.

Previously, Xu Shiyan's invention of cake fertilizer for ginseng has obtained relevant technical appraisal.

A few days ago, the ginseng field called to report the good news, saying that this year's ginseng field has achieved a bumper harvest, which is more than 30 percent higher than last year's yield.

This year, the ginseng field is in the form of base fertilizer and fertilization, so the yield of ginseng has increased significantly.

The county secretary also made a special call to Xu Shiyan, saying that the yield of ginseng land everywhere this year is good, and the results of ginseng fertilizer are gratifying.

The most outrageous thing is that Su Anying called to say that the deer manure on the farm has become fragrant.

Many places came to order deer manure, and went back to compost and ferment it to make fertilizer for ginseng.

"It's okay to say that the bean cake is too restricted.

Moreover, each person has a different degree of fermentation technology, which actually affects the utilization rate of this fertilizer.

If we can formulate a better recipe and mass produce it, I think it will be better than the current one.

Especially in the aspect of heavy ginseng soil, if it can resist soil compaction, enrich the soil microbial flora, and supplement various nutrients required for the growth of ginseng.

It will definitely be very helpful for the effective use of ginseng. ”

The so-called heavy ginseng soil means that a stubble of ginseng has been planted, and after a few years there is no ginseng soil, and you want to reuse the ginseng, this is heavy stubble.

Ginseng is a serious fertility drain on growth, and it can be said that it is a predatory absorption of the soil.

Therefore, where ginseng has been planted, it will not be able to recover for ten or twenty years.

In addition, in the soil where ginseng has been planted, a lot of miscellaneous bacteria will be produced, and if the stubble is repeated, many germs will appear, causing the ginseng to rot.

This is also a big problem faced by the development of the participation industry.

After all, forest resources are limited, and there will be less and less land that can be planted with ginseng, so it is a big problem to improve the utilization rate of ginseng soil.

Xu Shiyan knew that with his current level, he couldn't do it to this extent, so he took the opportunity to ask the academy tutor for help.

The tutors of the Agricultural University have their own unique skills, and maybe they can find a way.

"Well, that's a bit interesting.

Microbial technology is used to provide the necessary nutrients for ginseng growth, restore soil fertility, and play a role in sterilization and disinfection.

It's a bit difficult, but it's a good idea to study as a subject. ”

One of the mentors was very interested in the idea proposed by Xu Shiyan, and he decided to take someone to study it.

"By the way, you can talk about the foliar fertilizer, I remember that there was a method of diluting calcium superphosphate with water and spraying it before.

What do you think about biotechnology? ”

Another mentor was interested in what Xu Shiyan said about foliar fertilizer.

"It is to use microbial fermentation and extraction technology to extract nucleotides, a variety of amino acids, fulvic acid, trace elements, etc., and prepare foliar fertilizer.

I think this will be a development trend in the future, which is conducive to environmental protection and renewable resources. ”

"The growth period of ginseng rhizomes is from July to September, and at this time, the fertilizer applied in the early stage can no longer meet the needs of ginseng growth.

Spraying foliar fertilizer can supplement the lack of ginseng nutrients, promote stem and leaf growth, disease resistance, and lodging resistance.

Superphosphate is still too simple to supplement all the nutrients needed for ginseng growth.

And superphosphate is, after all, a mineral and a non-renewable resource.

There was a phosphate fertilizer factory in our county before, but it stopped production because of the lack of raw materials. ”

The last one is the most important reason.

It should be said that Xu Shiyan, who has two lifetimes of experience, is absolutely the most advanced and top in the ginseng planting industry.

So the theories he put forward are really fascinating.

Don't look at the professors of Agricultural University on the other side, but in this aspect, no one can compare with Xu Shiyan.

"Well, I think this is more interesting, let's do it, and we'll leave it to you.

You go back and write your book first, and then let's set up a special research group to study this problem. ”

They are all experts in related fields, and they know what Xu Shiyan said when they hear it, not to mention it in China, even in the world, it is also a very advanced concept.

If the research is successful, it is likely that it will be used not only in the field of ginseng cultivation, but also in other crops.

This is a good thing and must be taken seriously.

In this way, Xu Shiyan, who put forward two new theories, continued to bury his head in a pile of manuscript papers, fighting at night and writing hard.

On the side of the college, we really convened a meeting to discuss related topics, and after research, it was decided to set up relevant research groups.

Xu Shiyan, as the proposer of the project, and has rich knowledge in the field of ginseng cultivation, was naturally selected into the research group.

With a lot of elites in his eyes, he did all kinds of experiments.

Fortunately, Xu Shiyan wrote part of the book "New Technology for Ginseng Cultivation" when he was at home, and it was basically finalized by mid-October.

So he mailed the manuscript back to a staff station and was corrected by Lin Qiyue.

Then it was submitted to Jiang Yunfeng, deputy county magistrate and deputy director of the Ginseng Research Institute, who made the final review, and then submitted it to the publishing house for publication.

Of course, this is a long process, Xu Shiyan is only responsible for completing the first draft, and the rest has nothing to do with him.

Xu Shiyan can't take care of those, the most important thing at present is this biological compound fertilizer.

For Xu Shiyan, this is a rare opportunity, and it is also the biggest achievement of his two-year study at Agricultural University, so Xu Shiyan is very attentive.

And Xu Shiyan's serious and cautious attitude has also been praised by many mentors.

In fact, most of the students in the cadre special training class come to mix diplomas to improve their qualifications, and there are very few people like Xu Shiyan who can really specialize and study seriously.
