After leaving the city, the road becomes difficult to walk.

The bumpy truck and the crowded environment made Yang Rui a little drowsy. The only good thing is that it is warmer. The truck itself is enclosed. Then tie up the air leakage and use a thick green army coat to block it. Very comfortable.

Military coats are essential equipment for today's students. On the one hand, the materials used for military coats are real, and on the other hand, there are too few choices for winter clothes.

Yang Rui wears a British-style duffle coat. He has a slender figure and chooses a British-style winter coat. There is no problem in being comparable to a model.

However, in the environment of the truck's rear bucket, the British-style duffle coat is a bit out of place in a pile of military coats.

As a good young man of the 21st century, Yang Rui is somewhat habitually independent. At least he is unwilling to collide with others. However, the good young people of the 1980s seem to think more about not being separated from the collective.

When a group of people appear in the wilderness after getting out of the car, the effect of this sense of collectiveness seems to be even stronger.

However, Yang Rui has never cared about such things.

The person doing scientific research has stayed in the laboratory for a long time. It doesn't matter if there is anyone around him. Whenever he needs to chat, he just grabs a small white mouse. If he does it a little longer, he won't even deliberately grab the control group.

It doesn't hurt to be executed afterwards.

In contrast, botany is a subject that Yang Rui dabbled in very few. Although many people talk about biologists, they will ask him, do you know what flower this is?\/grass\/tree\/seed\/bug\/bird\/whip\/fur However, biologists don’t learn this.

Of course, if you don't learn it at all, you won't be able to, like Yang Rui, will come to a few field investigations now, but what you can learn is the general concept.

To understand plant taxonomy, it is basically a botanist's business. More accurately, it should be called a plant taxonomy. Moreover, there are too many types of plants or organisms on the earth, and they are experienced plants. Scientists usually just understand the field they are familiar with.

Of course, that means specific details.

On a large scale, scholars like Professor Xie Gaoyi, who specialize in plant taxonomy, can just glance at the leaves and know what it is.

He straightened the team a little bit, then let everyone surround him, follow him, and introduce the passing plants to everyone as he walked.

"This is a pine tree, everyone knows it, so I won't say more."

"Well, Shan Xing." Professor Xie Gaoyi pointed his left finger and walked over.

The students behind quickly looked up, and then began to take notes.

They soon learned that the speed of such notes could not keep up with the rhythm.

Because Professor Xie kept spitting out new nouns:

"Arborvitae."

"These are all Pinus tabulaeformis."

"The shrubs over there are lesbians, and there seems to be small leaf buckthorn. Well, they can all be used as Chinese medicinal materials. If they are too far away, they will not pass. Interested students and Master Lin can borrow the telescope.

As a result, the binoculars worn by the forest ranger, Comrade Li, immediately became a new hot item.

Bai Ling also wanted to take a look with the telescope, not only because it was easy to learn, but also because the telescope itself was attractive enough.

However, she saw that Yang Rui next to her did not move. After thinking about it, she didn't ask for it. If 25 people looked at a telescope, they had to line up for a while. She would rather follow Yang Rui, even if it is a snowfall.

Yang Rui noticed her movement, smiled, took out a small telescope from his arms and handed it to her: "You can use this to see if you want to."

The telescope Yang Rui took out was thinner than that of the forest ranger Lao Lin. It was more than three laps thinner. Bai Ling raised it with one hand and it was very relaxed. At the same time, the leather sheath also added a good friction, and made the telescope no longer. So cold.

Bai Ling was holding a telescope with Yang Rui's body temperature, her face flushed, and then she lifted it up and looked in the direction pointed by Professor Xie.

In the winter of Northland, there is always a sense of depression in the wild.

But in Bai Ling's eyes, it was thick and warm.

"Yang Rui, the telescope you bought yourself?" Monitor Liu Pingan slowed down, waiting for Yang Rui and Bai Ling in front.

Yang Rui smiled and said, "I borrowed it."

Liu Pingan said "Oh", and said, "Can you use it with your classmates? It won't be broken for you."

"When Bai Ling finishes reading it, you can switch to it." Yang Rui didn't care who had the telescope in his hands.

When Bai Ling heard their conversation, she immediately put down her binoculars and said, "Yang Rui, don't you look at it?"

"I'll look at it later, I don't have much interest in these plants." Yang Rui came with the binoculars, which was easy at first. Furthermore, there is really nothing to look at when you just entered the Badaling forest area. Only the rookies who participated in the field survey for the first time would be excited when they heard the Pinus tabulaeformis.

Seeing that Yang Rui was not humble, Bai Ling handed the binoculars to Liu Ping'an, and said, "Then I'm finished reading it, let's see."

"Okay, thank you, so I can see it faster." Liu Ping'an excitedly handed the binoculars to the classmates around him, but he didn't even raise it to look at it, for fear that others would say he was looking for it for himself.

There are two telescopes to look at, the speed of the alternation is naturally much faster, and there is less queuing.

At this time, Professor Xie became unhappy. He snapped his hands twice and said: "Everyone pay attention to the trees nearby. The trees in the distance can see better, but the closer ones are the focus of today. , Everyone can observe the main characteristics of plants, well, let me find an example..."

Xie Gaoyi talked about wherever he thought of, and only found examples in the woods when he talked about it. It was also that he hadn't taught undergraduates for a while, and was a little rusty, but on the other hand, he was also brave and courageous. In the woods, still in the Badaling forest area of ​​Beijing, there are so many materials for him to use for teaching.

After walking for two minutes, Xie Gaoyi stopped, opened the marching pot and took a sip, and said: "Let's wait for the students behind, I will tell you how to pay attention to the main characteristics of plants."

When the two dozen people arrived, Xie Gaoyi paid special attention to Yang Rui's position, deflected his body, and said: "Look, everybody, there are two trees behind me, one of them is Pinus tabulaeformis and the other is Pinus thunbergii. We saw Pinus tabulaeformis as soon as we entered the forest area, and I also pointed it out to everyone. Now let’s look at it. What is the difference between Pinus tabulaeformis and Black pine?

College students in the 1980s were very active. Some students raised their hands and said: "The bark of the black pine is darker, and the Chinese pine is grayer."

"Yes, that's why the black pine is called black pine." Xie Gaoyi nodded his head and said again: "The bark of the Chinese pine is actually a little red. It is easier to identify when the sun is good."

Motivated, someone then cried out: "The pine leaves of the black pine are thicker."

"Yes, if you compare it, the needles of the black pine are thicker and longer, and the Chinese pine is not only thinner, but also softer and slightly drooping." Xie Gaoyi said, pulling the needles of the Chinese pine a little and showing them to everyone. For a moment.

Yang Rui's two coughs were used to cover up the sound of his almost laughing.

Bai Ling first heard the prelude of laughter, and then heard Yang Rui's coughing. She couldn't help looking at him with some concern, and said with a smile: "Be careful of catching a cold."

"It's okay." Yang Rui replied softly.

In order to avoid harassing other classmates, Yang Rui whispered very close to Bai Ling. The temperature in winter is very low, and the warm breath sprayed into Bai Ling's ears, making her feel itchy and happy.

Even if I lived in the forest all my life, I would be very happy with Yang Rui... Bai Ling thought silently, the whole person would be distracted.

Seeing this scene of Xu Anqing, the corners of his eyes burst.

It's not that he has any thoughts about Bai Ling, but why does the fair lady always stare at such a dish like Yang Rui? I am also excellent, am I not?

To be honest, Xu Anqing has not wanted to compare with Yang Rui for some time, especially after the Lu Boding incident, Xu Anqing ignored Yang Rui. He tried his best not to think about it, not to see Yang Rui, and not to read Yang Rui. The newspaper of the name, so far, everything is going very smoothly.

But he didn't expect that he and Yang Rui would collide with Yang Rui when he reported to the field survey well, and the order in the line seemed to be disrupted.

Xu Anqing can accept that Yang Rui is better than himself in academic terms. It is no longer acceptable to not accept it. However, in terms of male charm, Xu Anqing still has a certain degree of self-confidence. After all, Yang Rui's family is just a small township cadre, and his * Birth is incomparable. For girls who are a little ambitious, they should be more realistic.

He didn't expect that Bai Ling, a girl in this class, would have been fascinated by Yang Rui without looking at other people.

"Professor Xie, I think the difference between black pine and Chinese pine is the most obvious." Xu Anqing raised his hand angrily. His observation ability is better than that of ordinary people. Stable.

Professor Xie nodded to Xu An and said: "Yes, for black pine and Chinese pine, there are new buds at the top of their branches every year. The colors of the new buds are different. It is winter now, which is not very obvious, but observe carefully. For these two trees, everyone should still be able to find pine buds that have not yet fully developed."

He pointed to both sides ~lightnovelpub.net~ and said: "You can see that the buds of black pine are white, and the buds of Chinese pine are brown-red, so black pine is also called Baiyagong. This is the biggest similarity and difference between the two trees and an absolute criterion for judgment."

The students squatted their feet to watch, and some opened their notes to take notes. Now that there is no Internet, fragmented knowledge can only be recorded and sorted by yourself. Otherwise, it is very difficult to find a specific and subtle Chinese similar book.

Professor Xie had a good impression of Xu Anqing. Standing behind him, he said with encouragement: “In our plant taxonomy, discovering taxa, or re-dividing taxa through research, is one of the most important tasks. To make a difference, we must have the observation power of this classmate. Among so many plants, it is difficult to say whether there are new species or even new taxa that have not yet been discovered. How to find them? We now have a lot of scientific research. Method, but the role of human beings is still the most important. Everyone is an elite student of Peking University. I hope that some of you will one day discover new species and determine new taxa. Therefore, you are interested in this. Classmates, starting from today, we must cultivate our keen observation skills."

The students nodded one after another, and Xu Anqing let out light in his eyes, as if he saw a path to defeat Yang Rui, or at least a curve to defeat Yang Rui.
