The bumpy truck and crowded environment made Yang Rui a little drowsy, the only good thing was that it was warmer, the truck itself was fenced, and then tied up the leaky place and blocked it with a thick green army coat, it was very comfortable.

Military coats are a must-have equipment for students today, on the one hand, the materials used in military coats are real, and on the other hand, there are too few choices of winter clothes.

Yang Rui is wearing a British-style tweed coat, his figure is slender, and there is no problem in choosing British-style winter clothes to be comparable to a model or something.

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

As a good young man in the 21st century, Yang Rui is a bit habitually maverick, at least he is unwilling to collide with others, however, the good young people of the 8O generation seem to think more about not detaching from the collective.

When you get out of the car and a group of people appear in the wilderness, the effect of this sense of community seems to be stronger.

However, Yang Rui has never cared about this kind of thing.

A person who does scientific research has been in the laboratory for a long time, and it doesn't matter if there is anyone around him, when he needs to chat, he can just catch a guinea pig, and if he does it for a longer time, he will not even go out of his way to catch the control group.

After that, he was executed without sadness.

In contrast, botany is a subject in which Yang Rui dabbles very little. Although many people talk about biologists and ask them, do you know what kind of flower/grass/tree/seed/bug/bird/whip/fur is, biologists don't really learn this.

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

If you want to understand plant taxonomy, it is basically a matter of botanists, and it is more accurate to call it plant taxonomists, and there are too many species of plants or organisms on the earth, that is, experienced botanists, usually just know the areas they are familiar with.

Of course, that's talking about the specifics.

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

After a little regrouping, he gathered everyone around and followed him, introducing them to the plants they passed by.

"This is a pine tree, I know it all, so I don't want to say more. ”

"Yes, Yama Xing. Professor Xie Gaoyi pointed his left hand and walked over.

The students in the back hurriedly looked up, and then began to take notes.

They soon learned that such a degree of note-taking could not keep up with the rhythm.

Because Professor Xie kept spitting out new terms:

"Arborvitae. ”

"These are all Pinus tabuliformis. ”

"The shrubs over there are bush branches, and there seems to be a small leaf buckthorn, well, they can all be used as Chinese medicinal materials, and if they are too far away, they will go there, so interested students and Master Lin will borrow a telescope. ”

As a result, the binoculars worn by the forest ranger Comrade Lao Li immediately became a new sought-after commodity.

Bai Ling also wanted to take a look at the telescope, not only because she was studious, but also because the telescope itself was attractive enough.

However, she saw that Yang Rui next to her didn't move, and after thinking about it, she didn't ask for it, 25 people looked at a telescope, and they had to queue up for a while. She would rather follow Yang Rui, even if it is to step on the snow.

Yang Rui saw her movement, smiled, took out a small telescope from his arms, handed it to her, and said, "If you want to see it, you can use this to see it." ”

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

Bai Ling was holding a telescope with Yang Rui's body temperature, her face couldn't help but redden, and then she raised it up and looked in the direction that Professor Xie pointed out.

In the winter of the northern country, there is always a feeling of depression in the wilderness.

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

"Yang Rui, did you buy the telescope yourself?" Liu Ping'an, the squad leader, slowed down his pace and waited for Yang Rui and Bai Ling in front.

Yang Rui smiled and said, "Borrowed it." ”

Liu Ping'an let out an "oh" and said, "Can you use it for the classmates in the class?" ”

"When Bai Ling finishes reading, you can watch it instead. Yang Rui doesn't care who the telescope is in.

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

"I'll look at it later, and I don't have much interest in these plants. "Yang Rui came with a telescope, which was originally convenient. In addition, when you just enter the Badaling forest area, there is really nothing to see, and only rookies who participate in field surveys for the first time will be excited when they hear about Pinus tabuliformis.

Bai Ling saw that Yang Rui was not modest, so she handed the telescope to Liu Ping'an and said, "Then I'll finish reading it, you can see it." ”

"Okay, thanks, so you can see it a little faster. Liu Ping'an excitedly handed over the telescope to the classmates around him, but he didn't hold it up to look at it, for fear that others would say that he was looking at it for himself.

There are two telescopes to look at each other, and the alternation is naturally much faster, and the queue is suddenly less.

At this time, Professor Xie became unhappy, snapped his hands twice, and said: "Everyone pay attention to the trees in the distance, the trees in the distance can be seen better, but the near ones are the focus of today, the distance is close, everyone can observe the main characteristics of the plant, well, let me find an example......

Xie Gaoyi talked about it wherever he wanted, and only when he talked about it did he find examples in the woods, but he also didn't give big classes to undergraduates for a while, and he was a little rusty, but on the other hand, he was also a skilled person who was bold, and he was in the woods, or in the Badaling forest area of Beibei, and the materials that could be used for teaching were really too much for him.

After walking for less than two minutes, Xie Gaoyi stopped, opened the marching pot and took a sip of water, and said, "Let's wait for the students in the back, I'll tell you how to pay attention to the main characteristics of plants." ”

When more than two dozen people arrived, Xie Gaoyi deliberately paid attention to Yang Rui's position, deflected his body, and said: "Look, the two trees behind me, one is a pine and the other is a black pine, we saw it as soon as we entered the forest area, and I also pointed it out to everyone, you can observe it now, what is the difference between pine and black pine?"

The college students in the 80s were very active, and one of the students immediately raised their hands and said: "The bark of the black pine is darker, and the pine is a little grayer." ”

"That's right, that's why the black pine is called the black pine. Xie Gaoyi nodded in approval, and said: "The bark of the pine tree is actually a little red, and it is easier to identify when the sun is good." ”

Motivated, someone shouted again, "The leaves of the black pine are thicker." ”

"That's right, in comparison, the pine needles of black pine are thicker and harder, and the pine is not only thinner, but also softer and slightly sagging. Xie Gaoyi said and pulled down a little of the pine needles of the pine pine and demonstrated it to everyone.

Yang Rui coughed twice, to cover up the sound of his almost laughing.

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

"It's fine. Yang Rui replied softly.

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

Even if you live in the mountains and forests all your life, if you live with Yang Rui, you are very happy...... Bai Ling thought silently, and the whole person was about to wander.

Seeing this scene, Xu Anqing's eyes were about to explode.

It's not that he has any thoughts about Bai Ling, but why does My Fair Lady always stare at Yang Rui's dish? I'm also very good, aren't I?

To tell the truth, Xu Anqing has not wanted to compare with Yang Rui for a while, especially after the Lu Boding incident, Xu Anqing ignored Yang Rui, he tried not to think about it, did not see Yang Rui, did not read newspapers and periodicals with Yang Rui's name, so far, everything is going smoothly.

But he didn't expect that after reporting a field investigation, he bumped into Yang Rui again, and the order of the previous queue seemed to be disrupted.

Xu Anqing can accept that Yang Rui is better than himself in academics, and it is no longer possible to accept it, but in terms of male charm, Xu Anqing still has a certain degree of self-confidence, no matter what, Yang Rui's family is just a small cadre in the township, and the birth of his high-ranking cadres cannot be compared.

He didn't expect that Bai Ling, a girl in this class, would not look at anyone else with Yang Rui's fascinated eyes.

"Professor Xie, I think that compared with black pine and pine tabuliformis, the difference between pine buds is the most obvious. Xu Anqing raised his hand angrily, his observation power was already better than ordinary people, although he was in a turbulent mood, it was still very stable to play everyone to find fault.

Professor Xie looked at Xu An's green jaw and said: "Yes, for black pine and tabuliformis pine, there will be new shoots at the top of their branches every year, and the color of the new shoots is different, it is already winter, it is not obvious, but if you look closely at these two trees, you should still be able to find the pine buds that have not yet been fully grown." ”

He pointed to both sides and said, "You can see it, the pine buds of the black pine are white, and the pine buds of the pine are brownish-red, so the black pine is also called the white bud gong." This is the biggest similarity and difference between the two trees, and it is the absolute criterion for judging. ”

The students scrambled to look at it, and some opened their notes to take notes. Now there is no Internet, fragmented knowledge can only be recorded and sorted out by itself, otherwise, it is very difficult to find a specific and micro similar book in Chinese.

Professor Xie had a good impression of Xu Anqing, standing behind him, and said with encouragement: "In our plant taxonomy, the current taxa, or through research, re-dividing the taxonomy is one of the most important tasks, and if you want to make a difference in this area, you must have the observation power of this classmate." There are so many plants, it is difficult to say whether there are new species or even new groups that have not yet appeared, and how to find them? We now have many scientific methods, but the role of man is still the most important. I hope that some of you, one day, will be able to discover new species and identify new groups, so students who are interested in this should cultivate their keen observation from today. ”

The classmates nodded one after another, and Xu Anqing's eyes lit up, as if he saw a path to defeat Yang Rui, or at least the curve to defeat Yang Rui.
