Chapter 619 Weeds
Jiang Yuan looked Pang Jidong up and down.To be honest, when it comes to the functionality of forensic botany, he is not as confident as Pang Jidong at the moment.

Pang Jidong looked at Jiang Yuan excitedly, his expression seemed to say: Look at my guess, right!I guessed it right!

For the purpose of encouraging teaching, Jiang Yuan asked: "How do you think you can find the place to bury the corpse?"

"I see that you worked on the Litang Township case before, didn't you find the buried corpse through the vegetation?" Pang Jidong asked.

Jiang Yuan was a little stunned by the question, shook his head, and said, "That's much less difficult, it's a judgment in a small area. And I happened to see it, and I didn't specifically look for it."

"But it should be possible to make a judgment." Pang Jidong learned for so many days, and it really wasn't for nothing.Moreover, the main direction of his learning is how to use forensic botanists, rather than actually doing it himself.

Although he knew that what Pang Jidong had learned was quite difficult, based on his current understanding, it seemed that Jiang Yuan could do it.

Jiang Yuan looked at the map again, coughed and hesitated a little.

This work is comparable to some investigations. The difference is that an investigation is a group of people who search cautiously, for fear that all previous efforts will be wasted because of missing a point.But using forensic botany to find corpses, he had to search carefully alone, not to mention boring, and the work efficiency would not be very high.

The most important thing is that this approach is very difficult and there are few precedents. In the end, if he can't do his best, it will be difficult for Jiang Yuan himself to accept it.

"Jiang Yuan, try it." Seeing this, Liu Jinghui said something, and then said, "If you don't do it, you can only find Xu."

"Ai ai ai ai... No matter how you say it, you say it is crooked..." Huang Qiangmin was silent at the side, but now he couldn't sit still, and hurriedly said: "This is our own money in Ningtai County, don't worry about it." Spoiled."

According to the lines drawn by Liu Jinghui, the search and investigation is similar to the investigation of the more than 100 kilometers of national roads in Luyang City, and the difficulty may be a little more difficult.The advantage is that in the county, the supply is more convenient, and there will definitely be more troubles.

But no matter how simple it is, as long as Luyang City costs [-]%, Ningtai County can't afford it.

Even though Jiang Yuan sold it so many times, all he got in exchange were supplies, and the cash of the Ningtai County Bureau was still tight.If it is time to spend money, there is no way, but right now, it is obviously not that urgent...

Huang Qiangmin held Jiang Yuan with one hand, and Liu Jinghui with the other, and said, "Let's discuss it carefully, and don't waste money every now and then. Ningtai is a poor county, and it's not easy to save a little money. Jiang Yuan, you just use that." Botany, can you do it?"

"Even if it's flying a drone, it's too time-consuming to look at it piece by piece. If I'm alone..." Jiang Yuan said this, looked at Pang Jidong, and asked, "Have you tried to find a botanist?" Bar?"

"Yes." Pang Jidong nodded quickly, and said, "Would you like to come over and have a try?"

"It would be best if you could come here." Jiang Yuan hurriedly said.It's a different story when someone helps you.

"It's okay. I'll call. How many people please?" Pang Jidong took out his mobile phone.

"A few...the more the better. Can you invite a lot?"

"I've found four or five people now. They are all researchers at the Institute of Botany, or professors at the school. Those who have a team. Let's see how many people can come."

Jiang Yuan was surprised: "I see that the police in foreign countries, it is quite difficult to hire experts and so on, and the cost is also quite a lot."

Pang Jidong smiled while sending WeChat and text messages: "How can the foreign police compare with our domestic police? We are the people's police. Besides, no matter how hard everyone scolds the experts, these powerful botanists are still very good. Those who have ideals, I tell them they can apply what they have learned, people don’t even care about money, and they buy round-trip tickets by themselves.”

This part is really something that Jiang Yuan has never touched, so he can only nod obediently.

The task force got busy.

According to the line drawn by Liu Jinghui, the police force released multiple drones for low-altitude shooting.This part of the technology is already very mature. The demolition offices that ordinary families often encounter will fly drones to take pictures of all the conditions on the ground, so as to prevent people from building indiscriminately after the demolition announcement is issued. Plant trees to reclaim wasteland.

At the same time, Huang Qiangmin transferred the entire police dog squadron to try to use it on the scene.

The experts invited by Pang Jidong arrived at noon at the earliest, which can be called a race against time.

In the afternoon, several botanists arrived at the meeting room of the Ningtai County Bureau one after another—the meeting room of the Zuomadao Police Station was too simple, and Huang Qiangmin felt that outsiders should not be misunderstood about the working conditions of the people's police.

Jiang Yuan sat in the conference room very early, looking at the screen and taking notes, and greeted botanists when they came in, and did not socialize too much.

Liu Jinghui drew a total of 5 routes, and the area to be seen is very large, and everyone will have a full workload.

The last botanist to arrive at the Ningtai County Bureau was Su Lei, a tall female researcher wearing a professional suit and silk stockings, with long and slender legs.

As a result, the number of people in the conference room has increased by several people, and the botanist who came in front also politely introduced the situation, saying: "Now is the preliminary screening stage. Everyone claims an area or line, and then interprets it on the computer. Report the result, but it is recommended to record it in the notebook and submit it in a centralized manner later. Corpses will not run away."

"Okay." Su Lei agreed, and then asked: "How did you find it?"

"I found a lonely grave, which was buried three or four years ago. The time is not right, it should be buried secretly by local people. The police have been sent to find someone." Jiang Yuan replied.

Su Lei laughed: "It's so interesting to work with the police?"

"I'm a policeman." Jiang Yuan pointed to his epaulettes, and introduced himself: "I'm a forensic doctor from Ningtai County Bureau."

"I know, Officer Pang said that you understand forensic botany. Actually, I'm quite skeptical. Does anyone really understand forensic botany?" Su Lei is a real professional, and the questions she asked are actually very professional, and said : "I think forensic botany is a bit of a false proposition. Botany involves too much information. Is it too difficult to work part-time forensic and botanist?"

In fact, it does.

If Jiang Yuan didn't have the help of the system, he would definitely not be too eager to challenge forensic botany.

This kind of technology is the knowledge that really needs systematic education to master. It belongs to the knowledge that can be mastered before graduation.

Jiang Yuan couldn't explain his situation, so he could only spread his hands and said, "Forensic botany is really difficult, and we tend to look for mature botanists now. I'm special."

"It's really special." Su Lei said as she approached Jiang Yuan.

Before she started working, she walked over to look at Jiang Yuan's work screen, and glanced at Jiang Yuan's notebook by the way.

At a glance, Jiang Yuan memorized the names of a lot of weeds, such as crabgrass, goosegrass, purslane, lacquer...

Su Lei understood in seconds, and said, "Soil disturbance?"

"Yes." Jiang Yuan nodded.

Soil disturbance will transmit various environmental influences to plant seeds in the soil and induce growth.The principle of this thing is also related to the "seed bank".A seed bank is when the soil contains the seeds of all the nearby plants, but when the conditions are not right, the seeds are like in a bank, just kept in place for a rainy day.

And when the soil is disturbed, the seeds in the disturbed soil will think that the time has come, and then they will scramble to grow.

This is also the principle of vegetation changes in the burial ground.

Initially, the burial site will become barren, and then a large number of plants will scramble to grow.

Because most of the weeds are stored in the seed bank, and those with low growth requirements are also weeds. Therefore, after the burial site is barren, the second indication is the weeds.

But in the end, it all comes down to competition, and the more competitive plants will eventually cover the burial ground.

It must be explained that the plants near the burial site will not grow very lush.

The rules of change vary from place to place and from time to time, requiring botanists to observe and accumulate information.

This is what Jiang Yuan is doing.

Su Lei only looked at Jiang Yuan's notebook and understood his working mode, and then her expression became serious.

"I'll choose this one. Line C." Su Lei returned to her seat, selected the line, and began to work hard.
