Lin Xing'an took the unknown plant in Ling Zikai's hand, looked at it carefully for a while, and said with some surprise: "This can't be the legendary lewd dragon grass, right!

"I saw this fruit growing very brightly beside a waterfall, and I was a little curious, so I dug it up. Uncle Lin, is this fruit a medicinal herb and does it have any special effects?"

Lin Xing'an explained: "Although I have never seen this plant before, I once saw a record of a plant in a document in the library of Lin University. It is said that there is a rare plant in the Xing'an Mountains, the plant resembles an orchid, can flower and bear fruit, and the fruit is larger than the cherry, but it is now extinct. This fruit has only one effect----"

Speaking of this, Lin Xing'an glanced at Ling Zikai, his expression was a little strange, he lowered his voice, and said, "Actually, you don't need me to explain, just from the name of this plant, you should guess it." Its greatest effect is aphrodisiac, which is even more powerful than the so-called *, you kid must not eat it because of greed. ”

As he was talking, He Ling came over curiously after seeing the lewd dragon fruit in Lin Xing'an's hand, and said, "This cherry is so big, take one for me to taste." ”

Ling Zikai hurriedly snatched back the lewd dragon grass from Lin Xing'an's hand and said, "Who said this is a cherry, this fruit is poisonous!"

He Ling didn't believe Ling Zikai's words at all, and said disdainfully: "Look at your stingy bear-like, isn't it just a few wild fruits, what's rare." And lie that it's poisonous, you treat me as a child!"

Ling Zikai lazily explained to her and put the lewd dragon grass into a bag.

Lin Xingan said solemnly beside him: "Miss He, Xiao Ling, he didn't lie to you, this fruit is indeed poisonous." Also, I would like to remind you that there are many wild fruits in this primeval forest, and you must not be greedy for those fruits that you can't tell what kind of fruit they are, and you should not eat them in a hurry. There are many wild fruits that contain poison. Especially those fruits that look particularly showy, they can't be eaten, some of them are highly poisonous, and if you eat them by mistake, you are likely to die!"

He Ling asked puzzledly, "Why are the flowery-looking fruits more poisonous?"

"Do you need to ask such a simple question? The brightly grown fruits are so striking that you can find them from afar. And there are a lot of animals in the woods like squirrels that like to eat wild fruits, so why don't they go to eat them? If they can, will it be your turn?"

Lin Xing'an nodded and said, "That's right, that's the reason." Sometimes, animals are much more sensual than we humans. ”

Seeing that Lin Xing'an said cautiously, He Ling also restrained the curiosity in her heart, turned around and continued to pack her things.

Ling Zikai asked Lin Xing'an, "Uncle Lin, can this lewd dragon grass be cultivated?"

Lin Xing'an asked puzzledly, "Do you want to plant lewd dragon grass in the forest farm?"

Ling Zikai nodded.

"This lewd dragon grass belongs to the orchid family, so it should be similar to the cultivation method of orchids. But I advise you to give up this idea as soon as possible!"

"Why?"

"According to the records, it takes more than 50 years for the dragon grass to bloom and bear fruit, and it only blooms and bears fruit once in a lifetime. If the rate of reproduction is fast, it will not become extinct. Besides, it is only this kind of effect, and it doesn't have much cultivation value!"

Lin Xing'an was a little unimpressed, but Ling Zikai's mind had already been activated.

He really wanted to say to Lin Xing'an: My Uncle Lin, the value of this lewd dragon grass is extremely high, do you know how much an authentic viagra will cost on the market now?

Do you know what percentage of men in the world today have declining sexual function?

If you can really cultivate a large amount of lewd dragon fruit, the benefits will definitely be countless times higher than the previous beauty cream.

After all, whether the appearance is good or not is just a sensory enjoyment. This lewd dragon fruit is not only related to the lifeblood of men, but also the happy life of the other half of the sky.

For Ling Zikai, entering the mountain this time, just getting the lewd dragon grass is already a great harvest.

The gift given by the little white horse was so precious that in the days to come, Ling Zikai's intimacy with the little white horse made a rocket-like leap.

After packing up their things, everyone continued to set off towards the old forest.

At noon, we came to the edge of the old forest.

During the break, Lin Xingan introduced the specific situation of this collection operation.

According to his plan of action, the seeds to be collected in the old forest this time cover almost every subtype of plants.

From gymnosperms to angiosperms, as well as bryophytes, ferns, and even algae are collected.

The names of those phylasects alone made Ling Zikai dizzy, let alone remember and distinguish those specific plants.

Among the five people, Lin Xingan and Zhang Nan have professional knowledge, and the other three can only start.

The five of them were divided into two groups.

Ling Zikai and Lin Xing'an were in a group. Specifically, Lin Xing'an is responsible for finding the target of the plant, and Ling Zikai is responsible for the specific work of collecting, recording, numbering, and marking.

He Ling and Zhang Nan are a group, with Zhang Nan as the leader, and He Ling is responsible for recording, numbering, and marking. Considering that they were girls, Su Guoer was assigned to them to do hard work such as gathering and carrying.

In order to avoid repeated collection and waste of time and energy, Lin Xing'an and his team were responsible for collecting gymnosperms.

Because gymnosperms are mostly trees, except for a few shrubs or vines, they need to climb on the trees to pick off the seeds when collecting, which is dangerous. At the same time, when encountering those plants that have no seeds, it is very laborious to dig up the seedlings by roots.

Angiosperms, bryophytes, ferns, and ferns mostly grow on the ground, so it is relatively simple to collect, and it can be regarded as taking care of girls.

After filling their stomachs, everyone started to act.

During the collection, Lin Xing'an briefly explained the knowledge of botany to Ling Zikai.

According to his explanation, gymnosperms are primitive seed plants with a long history of occurrence and development.

The first gymnosperms appeared in the Paleozoic, and in the Mesozoic to the Cenozoic they were the dominant plants found on all continents. It can be divided into cycads, ginkgo, pine, yew and mascus. Usually evergreen, with needle-shaped, linear, scaly-shaped, rarely flattened broad-leaved leaves.

More than 80 percent of the gymnosperms in the Xing'an Mountains are gymnosperms, such as larch, fir, Huashan pine, spruce and so on are important forest trees.

Their most striking feature is that the seeds do not have a foreskin and are bare, so they are called gymnosperms.

About 100 million years ago, gymnosperms flourished and declined, and angiosperms developed into the most widespread and diverse plants on the planet.

Angiosperms, also known as flowering plants and flowering plants, have real flowers, these beautiful flowers are important organs for their reproduction, and they are also the distinguishing feature that distinguishes them from gymnosperms and other plants.

In the plant kingdom, angiosperms are the most advanced class and the most perfect, adaptable, and late-appearing plants on the planet.

There are many species of angiosperms, accounting for almost half of the plant kingdom.

It varies greatly in habit, shape and size, from the tiny green floating grass to the huge tree eucalyptus, which grows upright, but also grows by winding, creeping or relying on the mechanical support of other plants.

Since the Cenozoic, they have dominated the planet. Because it has an extremely wide range of adaptability and can resist the internal conditions of various environments, it constantly produces new mutations and new species in the process of contradictory struggle between survival competition and natural selection.

Whereas, bryophytes belong to the category of green seedless plants.

It can be divided into mosses, mosses and hornworms. Most bryophytes are 2~5 cm tall, and a few are as tall as 30 cm.

Bryophytes are found all over the world, from the polar regions to the tropics, thriving most in humid environments and tolerant to prolonged dry and freezing conditions.

Lin Xing'an also solemnly said to Ling Zikai that if you want to build the entire Yunhai Forest Farm into a real primeval woodland, bryophytes will play a key role.

This is because bryophytes can live in moraines, deserts, tundra areas, and bare rock faces or newly fractured rock formations, following cyanobacteria and lichens.

In the process of growth, it can continuously secrete acidic substances, promote soil differentiation, and over time, that is, create soil conditions for other higher plants, so it is known as one of the pioneers of the plant world.

It has a great ability to absorb water, especially when it is densely clustered, its water absorption can reach 15-20 times of the dry weight of the plant body, and its evaporation is only 1/5 of the surface of clean water. It plays an important role in preventing soil erosion.

Like Sphagnum moss, Wet Moss, Great Wet Moss, Fusarium spp., etc., when growing in a large area by the lake and swamp, under suitable conditions, the upper part can produce new branches year by year, and the lower old plant body gradually dies and decays, therefore, the upper moss layer gradually expands over a long period of time, the lower part dies, and the decaying part becomes thicker and thicker, which can dry up the lake and swamp and gradually land it, creating living conditions for terrestrial herbaceous plants, shrubs and trees, so that the lake and swamp are replaced by forests.

Of course, as the saying goes, things must be reversed.

If the humidity in the air is too high, some of the above-mentioned mosses can absorb the moisture of water in the air, so that the water accumulates in the moss bushes for a long time, and can also promote the swamping of the ground, and form a high-level swamp. If a high-level swamp is formed in the forest, it is very harmful to the forest and can cause a large number of forest trees to die.

Therefore, it plays an important role in succession for the terrestrial and marsh of lakes and swamps.

In addition, bryophytes have only one layer of cells in their leaves, and toxic gases such as sulfur dioxide can invade the leaf cells from both dorsal and ventral sides, making bryophytes unable to survive.

If you take advantage of this feature, you can also use it as an indicator plant to detect the level of air pollution. Where moss appears, most of them have a good natural environment.

As for ferns, it is a general term for lowland wood-growing plants from the Devonian period. It is a relatively primitive group of higher plants, and it is also the earliest terrestrial plant. It is a herb that grows in the mountains and has a tenacious and vigorous vitality.

Ferns were once at the height of the Earth's history, and in the late Paleozoic era, they needed water as part of the regeneration cycle, and since then they have developed a variety of species.

It flourished in the Carboniferous period, when it was a tall plant that reached a height of 20-30 meters. It can be said that the high-quality coal on the earth was basically formed by the Carboniferous macroferns.

Algae plants are plants that live in water, including several different types of organisms that produce energy through photosynthesis.

This is the simplest and most primitive plant, which was originally developed from primitive photosynthetic bacteria.

Algae are varied, sometimes similar in appearance to the structure of roots, stems, and leaves of higher plants, but they can perform photosynthesis and release oxygen in function, so in fact the algae body is a simple leaf.

When these algae moved from the water to the land, the evolution of photosynthetic organisms accelerated dramatically, further evolving into bryophytes, ferns and seed plants.

In other words, algae plants are the ancestors of all plants.

Ling Zikai listened to Lin Xing'an's explanation with great interest, just like sitting in the classroom back then, listening attentively to the teacher's lecture, so that when He Ling's exclamation came from the forest, he didn't hear it.

Lin Xingan shouted at him: "There is an accident over there Zhang Nan, let's hurry over and take a look!"
