After getting up in the morning, Xu Yi washed up and went out of the dormitory building, which was different from the cold and deserted dormitory building of the graduating class, and the campus was still very lively.

When passing by the library, Xu Yi saw that the students who got up early to occupy a seat in the library had already stood in two long rows outside the library, looking at the crowd, Xu Yi couldn't help but sigh, if it wasn't for this bad thing, I was afraid that after I came back from home, before I graduated, I was afraid that I would still be a member of this army that occupied a seat.

There is no dedicated classroom in my class, and who knows when people are going to go to class in other lecture halls, which is rushed around, and I can't read a book if I want to.

Xu Yi went to the cafeteria, had a casual breakfast, and walked out of the school gate.

According to the plan, Xu Yi is ready to solve the problem of soil and water sample detection in the space today.

Xu Yi plans to go to the electronics market tomorrow to find out if there is a Geiger counter, to determine whether there is relatively weak ionizing radiation in this space, and then to see if there is, how strong the ionizing radiation index is.

As for electromagnetic pollution, Xu Yi still plans to use the soil method to test it temporarily, after all, this image of the human body is not particularly large, I checked it on the Internet, this spectrum tester is often tens of thousands of yuan a piece, and I have not really used this thing, how do I know how to measure?

Of course, if it is not in the space, no matter what you want to measure, you just need to call a professional to provide door-to-door service to ensure that the measurement is accurate.

Not only save money, but the conclusions you get are safer and more effective, but your own space is in your head, really let people in?

I really said to people, "Come, come to my head, and test me to see if there is any ...... in it."

This only proves one thing: I'm crazy.

And if someone really notices this thing in their head, whether it's good or bad, how can someone want to keep it for themselves, and it has to be kept as a cherished thing. But if you don't figure it out and don't test it, you can't rest assured.

Regardless of whether he can bring others in or not, at least before the test results come out, he doesn't dare to get any animals in it anyway, and even when he moved the cherry tree yesterday, Xu Yi was a little worried: whether this strange space would make the bacteria brought in by the cherry tree mutate.

Although there were no microorganisms that were co-infected by animals and plants in the past, it does not mean that this strange space will not mutate such things that can completely destroy the world.

Of course, because there is no chromosome examination item in the Chinese medicine hospital, Xu Yi didn't do this, but Xu Yi also thought about it, wait for the results to come out in two days, and then look at it, and if necessary, go to take a blood test, only in this way can he be completely reassured.

With the relocation of the Agricultural University, the Agricultural Research Institute was also relocated, but this time it was not moved next to the campus of the Agricultural University, but was relocated to the largest flower and bird market in the province next to the university town.

There is no direct bus from the school to the Agricultural Research Institute, so Xu Yi is afraid that it will be too late to go out, and he can't guarantee that he can really finish it in one day, and he doesn't know if there will be any procedures and processes in the middle that are not written on the Internet, so Xu Yi still went out early.

After a bus turn, Xu Yi finally stood next to the Agricultural Research Institute, and breathed a sigh of relief, after all, there are not many people paying attention to this Agricultural Research Institute, but the flower and bird market is different, this beautification of the living environment, the old man cultivates his temperament, and kills loneliness or something, all of which are a strong guarantee for the prosperity of the flower and bird market, although there are still a few small flower and bird markets in the provincial capital, but when it comes to scale and popularity, this market is the first, which makes this bus overcrowded, and they are all to the terminal.

After getting out of the car, Xu Yi looked up and found the place without much effort.

The most conspicuous thing diagonally opposite the bus stop is a four-story building with a few big characters on the top of the Foreign Service Center of the Agricultural Research Institute, and then look carefully, Xu Yi found that this building is simply at the door of the Agricultural Research Institute, and on the other side of the gate is a slippery building, looking at the name on it, Xu Yi knows that it is the store that sells testing equipment.

Xu Yi walked into the service center, glanced at the floor distribution map, and went directly to the second floor, here is the organic food testing or went directly to the testing window of the Agricultural Research Institute, and asked the staff inside: "Hello, I want to do organic agricultural product certification, is the soil and water sample testing handled here?"

"Yes, do you do it as a unit or as an individual?" a fat man in his thirties, who was almost in his thirties, raised his head and glanced at Xu Yi and asked.

"Personally. ”

"Do you know the application process for organic produce certification?"

"I know, but I don't want to apply for the whole project for the time being, I just want to test the indicators of my own land and water use first, if I can't get through guò, I know where the difference is, how to improve, and when the conditions are ripe to apply, I can also try to get a one-time pass." ”

"Then you apply for soil and water quality testing separately, the annex behind this agreement has a list of inspection items, and the indicators of organic agriculture environmental monitoring are consistent, you can take these two testing agreements back to see, if you confirm that testing is required, but be careful not to deface and fold. As he spoke, the fat man directly took the agreement and flipped through it page by page, and after confirming that there were no missing pages and content, he handed the list to Xu Yi.

Xu Yi took it and checked it too, and saw that the footer below had the total number of pages and the marks of the first few pages, and saw that the numbers could be matched, and he put them in the bag without confusion, and nodded at the fat man.

"Do you need us to provide door-to-door sampling business, or do you want to send samples yourself?" the fat man asked again.

"I'll send the sample myself. Xu Yi said.

"Do you need us to provide sample containment equipment?"

"Yes. ”

"Then you sign this application form, fill it out and take it to the toll office to pay the deposit, and then come and get the invoice. ”

Xu Yi looked at it, then signed it below, took it to the payment office, and put five hundred yuan, and then Xu Yi returned to the inspection window with the invoice and said to the fat man, "Hello, I have paid the fee, are you going to pick up the container here?"

"Yes, show me the payment slip. After taking Xu Yi's list, the inspector went out directly and moved two small cartons, handed them to Xu Yi, and then said: "You have a microbial testing project here, and you have to use the sterile bottled samples inside. If the thing is damaged, it needs to be compensated according to the price, and if it is not damaged, the cost can be paid to the inspection fee. However, the sterilized bottle is valid for no more than one week, if the sample cannot be delivered within a week, you need to come and replace the sterilized bottle, and you need to pay an additional disinfection fee."

"Well, okay, thank you. ”

Xu Yi walked out of the testing center with two cardboard boxes and walked towards the row of shops on the left.

The rest of the shovels and earth drills had to be bought by Xu Yi himself. Although when I checked on the Internet yesterday, I found that there are also bamboo poles or something to make zuò soil drills, but it is always impossible to be as convenient as a professional, and there must be problems such as difficulty in taking soil and pollution.

There was another reason that made Xu Yi dispel this idea: to do it himself, he had to buy materials and tools again.

After all, I live in the school, and I bring these things back by myself, who knows if it will cause onlookers, thinking that what I am doing is this, or spending money to buy it is the last word.

I checked it on the Internet yesterday, and there are dozens to hundreds of earth drills, and the price difference is so much, and the quality is naturally very poor, and Xu Yi definitely can't buy too bad, so the cheapest nickel-plated one is counted.

This electroplating thing, if you can't get it back, you can't use it, even if it can be used, the electroplating layer on it must be easy to fall off, and it will still rust and waste your life when the time comes, so Xu Yi plans to buy a stainless steel directly, which can measure a five-meter-deep soil drill, after all, he watched the "bathtub" come out of thin air from the ground, and the depth is almost four or five meters deep, so when the time comes, just pick some from shallow to deep, and the result may be more reliable. Using a homemade earth drill, who knows if it can be collected. As for buying somewhere else, one is that I don't know where to sell it, and the other is that there is no guarantee that the things I bought will meet the requirements.

Although Xu Yi stayed in the provincial capital for more than four years, but when he came to this place, he was still a big girl on the sedan chair once, where did he know which thing was trustworthy, so he casually found a store that sold inspection equipment, Xu Yi walked in, directly asked the price of the earth drill, and walked out politely, and then went to the next one to do the same thing, after comparing the prices of several houses, Xu Yi chose a shop with a medium price, and after bargaining with the boss inside, after buying a stainless steel earth drill, he discussed with the boss the precautions for use and maintenance, and Xu Yi took things out of the store,

"Money is not worth spending!" Xu Yi couldn't help but sigh, just such a small bag, it is more than 400 yuan, and it doesn't weigh a few catties when you pick it up, and it can be regarded as a lot of money. But at least this thing, Xu Yi doesn't feel that it is a loss to buy, at least if he really goes home in the future, if he wants to farm for a living, he is likely to have to send his own soil samples for testing, so as to ensure reasonable fertilization and effective soil improvement, and it can also be used, unlike the Geigh's counter, which can only be used this time, but if you don't buy it, can you rest assured?

Waiting for Xu Yi to buy good things and come out, the time was already noon, Xu Yi casually found a fast food restaurant with a large personal flow and ate a quick food, and then he was about to go back to school with his things, after all, he had to enter the space, and those protections had to be done.
