Chapter 457: Microbial compound fertilizer

??Chapter 457 Microbial Compound Fertilizer

??Xu Shiyan has to attend classes and is also in charge of writing the book "New Technology of Ginseng Cultivation". Now, he is even busier.

??In addition to class and meals every day, most of the time is spent in the library, or in the dormitory writing hard.

??The people in the same dormitory are all from neighboring counties. Although it is not as famous as Fusong for planting ginseng, there are also ginseng plants, and everyone knows about them.

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

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

?? I also specifically asked Xu Shiyan to go there, and was particularly concerned about the writing process of this book, saying that I would show it to the school first when the manuscript comes out.

?? Xu Shiyan did not object to this. One person counts on the shortcomings, and two people count on the long. It is time to brainstorm.

??Professors from the Agricultural University are all talented and learned. 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 proposed the idea of ??ginseng biological compound fertilizer and biotechnology foliar fertilizer.

?? "Teacher, this is my idea, which is to use complex microbial bacteria, such as 5406 strains.

?? Combined with compound amino acids, organic main materials, auxiliary materials, etc., and composted using bio-fermentation technology, it should be better than the previous ginseng soil fertilizer. "

?? This is an idea that Xu Shiyan came up with after reading countless related books and checking various documents after studying at Agricultural University.

??Before, the cake fertilizer for ginseng ground invented by Xu Shiyan had obtained relevant technical appraisal.

??A few days ago, the ginseng field called to announce the good news, saying that this year’s ginseng field had a bumper harvest, which was more than 30% higher than last year’s yield.

??This year, the ginseng field is the form of base fertilizer plus fertilization, so the output of ginseng field has been greatly increased.

??The secretary of the county also specially called Xu Shiyan, saying that the production of ginseng land in various places this year is good, and the results of ginseng land fertilizer are gratifying.

??The most outrageous thing is that Su Anying called and said that the deer dung on the farm has become delicious.

??Many places come to order deer dung, and go back to compost and ferment it as ginseng fertilizer.

?? "It's okay to talk about bean cakes, but the deer dung is really restricted too much.

?? Moreover, everyone has different degrees of fermentation technology, which actually affects the utilization rate of this fertilizer.

??If a better formula can be formulated and mass-produced, I think it will be better than the current one.

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

??The effective use of ginseng land will definitely be very helpful. "

??The so-called double cropping of ginseng soil means that after a crop of ginseng has been planted, there will be no ginseng soil in a few years, and you want to reuse the planted ginseng. This is double cropping.

??The growth of ginseng consumes a lot of fertility, which can be said to be a predatory absorption of the soil.

??So the places where ginseng has been planted will not be able to recover after ten or twenty years.

??In addition, in the soil where ginseng has been planted, a lot of bacteria will be produced. If it is replanted, many germs will appear, which will cause ginseng to rot.

??This is also a big problem facing the development of the participation industry.

??After all, forest resources are limited, and the land that can grow ginseng will become less and less. Improving the utilization rate of ginseng soil is a big problem.

??Xu Shiyan knew that with his current level, he could not reach this level, so he took the opportunity to ask the academy tutor for help.

??The instructors of Agricultural University each have their own unique skills, maybe they can find a way.

?? "Well, what you said is really interesting.

??Using microbial technology to provide nutrients necessary for ginseng growth, restore soil fertility, and at the same time play a role in sterilization.

?? It's a bit difficult, but it can be studied as a subject. "

??One of the mentors was very interested in Xu Shiyan's ideas, and he decided to lead others to study it.

?? "By the way, let's talk about the foliar fertilizer. I remember that there was a method of diluting calcium superphosphate with water before spraying it.

?? What do you think about biotechnology? "

?? Another mentor is interested in the foliar fertilizer that Xu Shiyan said.

?? "It is to use microbial fermentation and extraction technology to extract nucleotides, various amino acids, fulvic acid, trace elements, etc., to prepare foliar fertilizers.

??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.

?? Calcium superphosphate is still too simple to supplement all the nutrients needed for ginseng growth.

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

?? There used to be a phosphate fertilizer factory in our county, but it stopped production because of insufficient raw materials. "

??The last one is the most important reason.

?? It should be said that Xu Shiyan, who has two lifetimes of experience, has the most advanced and top-notch knowledge in the ginseng planting related industry.

??So the theories he put forward are really attractive.

?? Don't look at these are professors from Agricultural University, but in this respect, no one can compare with Xu Shiyan.

?? "Well, I think this is more interesting, let's do it, leave this matter to us.

??? Go back and write your book first, and then we will set up a special research group to study this issue. "

??They are all experts in related fields, and they knew what Xu Shiyan was talking about as soon as they heard it. At present, it is a very advanced concept even in the international arena, not to mention domestic.

??If the research is successful, it may not only be applied in the field of ginseng cultivation, but also other crops.

??This is a good thing and must be taken seriously.

?? In this way, Xu Shiyan, who proposed two new theories, continued to bury his head in a pile of manuscript papers, burning night and writing.

??The college really called a meeting of people to discuss related topics, and after research and decision, a related research group was established.

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

??Do various experiments with many elites in his eyes.

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

??So the manuscript was mailed back to a participating venue for correction by Lin Qiyue.

?? Then submit it to Jiang Yunfeng, the deputy county magistrate and deputy director of the Ginseng Research Institute, who will do the final review and then submit 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 anymore. The most important thing right now is this biological compound fertilizer.

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

??Xu Shiyan's conscientious and cautious attitude has also been praised by many mentors.

??Actually, most of the students in the cadre specialization class come here with mixed diplomas and qualifications. Like Xu Shiyan, they can really specialize, and few of them study hard.
