On the way back from the rainforest, Ye Han saw another tropical plant with great characteristics, the fake Ping Po.

The names evolved from Sanskrit, but their fruits are as distinctive as dipterocarp and are easily recognizable.

Ye Han took two fake Pingpo fruits and put them in his hands, which resembled starfish, showing an irregular pentagonal shape with five petals. The fruit is orange-red in color, and each petal is dehisced, and black seeds are hidden inside.

If you break off one of the corners, compare it to look like an open red lip.

Director Xu: "Ping Po and Fake Ping Po are also representative plants of the tropical rainforest. ”

Ye Han felt that these fruits were very beautiful and unique.

Sure enough, nature is the best designer.

Coming out of the rainforest, the two got on a sightseeing bus.

Ye Han was finally able to rest, she took off her hat and returned it to Director Xu, feeling the cool temperature of the air conditioner, and wiping the fine sweat oozing from her forehead.

The breathing gradually subsided, and the stuffiness from the rainforest gradually dissipated.

Maybe it's because I've seen the strangulation of the rainforest, the hanging garden, and other scenes that I don't usually see, and although my body is very tired, my spirit is very high.

The sightseeing bus drove to the West District, and Director Xu looked at Ye Han: "Director Ye, will the car send you directly to the door or do you want to go shopping again?" ”

"Let's go shopping again." Ye Han eased his breathing and said with a smile: "Trouble director." I heard that more than 20 special parks have been opened in the western district, and I hope to take this opportunity to see them. ”

"No trouble." Director Xu: "When we sit in the car, we treat it as if we were tourists. ”

The area of the West Ward is not small, and it is common to take a sightseeing bus to browse the park.

Ye Han saw a special banyan garden, which has a landscape of a single tree, which is also a major feature of the ficus plant.

Like the thousand-year-old weeping ficus seen before, the aerial roots that surround a circle behind the strangled tree are thick and powerful, and the length can reach seventy or eighty meters. They are coiled and knotted like hundreds of vines, and their aerial roots form pillars in the ground, which from a distance look like a waterfall – also known as 'tree falls'.

It is said that in India and other places, the aerial roots of the banyan tree are wound around to guide the growth and used to build wooden bridges.

The support and climbing ability of the banyan tree's aerial roots is truly amazing.

When he arrived at the palm garden, Ye Han saw a fallen bay leaf palm here.

Its origin is in India and other places, and it was introduced to our country for religious reasons. The leaves can be used as writing materials instead of paper, which is the carrier of the cultural inheritance of local ethnic minorities.

Therefore, the Dai culture is also known as Bayeux culture.

It is said that Tang Seng went to the west to learn scriptures, and what he took was the scriptures made by Bayeux Palm.

Director Xu: "The average lifespan of the bay leaf palm is 50-60 years, and it only blooms once in its life, and it will die quickly after flowering and fruiting.

This is a bay leaf palm that died after flowering last year, and our institute has made a specimen of it and placed it here to commemorate it. ”

Ye Han: "Director, are there really tens of millions of bay leaf palm flowers?" ”

Director Xu: "That's right, a single plant can bloom 24 million flowers, which is the largest number of flowering plants in the world. ”

It is a wonder that decades of accumulation have created such an astonishing number of flowers.

He showed Ye Han the photo.

When the flowering season arrives, the top of the bay leaf palm produces inflorescences, and then thousands of small beige flowers bloom, densely covering the entire canopy, covering the leaves below, which is very spectacular.

And the next one, the fruit-bearing bay leaf palm, the branches and leaves quickly decayed, and it is about to come to the end of its life.

Ye Han looked at such a scene, and his heart was full of indescribable shock.

This is the power of life to multiply.

Use all your strength to bloom, so that future generations can continue, so that life is endless.

And this is not uncommon in plants.

Director Xu: "Last year, there were seven bay palm trees in the botanical garden, which attracted a large number of tourists. ”

"And they've gone through the whole journey of life," he said. The next time I see such a view, it may be more than ten years later. ”

The cultivation of bay leaf palm is not easy.

The origin is in foreign countries, it is difficult to survive after transplanting, and there were only about 20 trees left in the last century, until now the development of seed cultivation technology has slowly restored its prosperity.

In addition to the bay leaf palm, there are various species of plants in the palm family.

Like oil palm, known as the world's oil king, palm oil yield per mu is as high as 200 kilograms, which is 5 times that of peanut oil and 10 times that of soybean oil, which is an important local cash crop.

……

Ye Han was sitting in the sightseeing car, and when he passed by some parks, he saw some trees with red signs.

According to Director Xu, this kind of plant or precious tree species is protected by the state, and it is now a key protection object.

For example, the sword leaf dracaena tree.

Ye Han has introduced plants of the same genus, which is more precious and is a national second-class protected plant.

The resin it flows out is called 'blood exhaustion', which is the same Yunnan red medicine as Yunnan Baiyao, and is also the main ingredient of the famous drug "Qili San", which has extremely high medicinal value. ①

Such an outstanding effect leads to it being often poached in the wild.

Therefore, artificial cultivation is very important.

As long as it can be cultivated on a large scale to achieve the same medicinal effect, these wild plants can be well protected.

Director Xu: "Now our botanical garden has cooperated with well-known pharmaceutical companies and nursery cultivation bases.

On the one hand, it provides them with technical support and uses funds for the construction of botanical gardens; On the other hand, it is also to protect these precious tree species. ”

Ye Han was deeply touched by this.

She thought of dendrobium.

Nowadays, large-scale artificial cultivation has greatly reduced its price, and the general public can buy it through formal channels.

Once there are alternatives and they are everywhere, who will go to great lengths to dig up wild species?

Moreover, this is an illegal act, and if you are not careful, you will be imprisoned.

Under the protection of various policies, poaching has been greatly reduced, benefiting the masses and making the price of medicinal plants cheaper.

*

After a long bus ride around the West End, it was almost 5 p.m., and the first day of the journey was a complete one.

Fu Yunze acted as the driver again and picked Ye Han back.

On the way back, Ye Han was quite eager to share, told what he had seen, and then asked him with a smile: "How are you doing today?" Did the partners give you a taste of the local area? ”

Actually, there is nothing

Who are the partners?

Fu Yunze's speed on the steering wheel paused slightly, and his bony fingers tightened: "... Yes. ”

Ye Han glanced at him.

Fu Yunze's ears were slightly red: "Have breakfast with you." ”

In this way, he himself felt that it was too straightforward, and added in a low voice: "I experienced the local special food. ”

Ye Han looked at the other party's handsome side face and reddish ears, and was slightly distracted.

She laughs and says, "Continue the experience that night – the local food?" ”

Fu Yunze was made breathless by her pause, and slowed down for a few seconds before saying, "Okay, I asked Pan Heng to order the hotel's specialty." ”

"By the way, I made an appointment with a masseur, I arrived at 8 o'clock in the evening, is the time okay?"

Ye Han: "Yes, thank you." ”

It's really convenient for someone to arrange these things.

It's only been two days, and Ye Han has already liked this kind of intimate arrangement.

Forget about nothing and focus more on what's important.

I don't know if I'll get used to it after returning to the flowers.

……

At night, Ye Han plays with the fruit of the Wangtian tree and confirms the plants to be introduced.

The first is the Wangtian tree, a national first-class protected plant and a world-class endangered species; At the same time, it is also introduced as a symbol species of tropical rainforests such as green plum/narrow-leaved slope of the dipterocarp family, as well as pseudonympha.

Then there are the national second-class protected plants: alder, alder, staghorn fern, swordleaf dracaena;

National third-class protected plants: see blood to seal the throat.

Bay-leaf palm is also very distinctive, such a shocking inheritance of life, Ye Han hopes to let more people feel it.

Dancing grass.

She writes about this plant.

Dancing grass is sensitive to sound waves, and the leaves will swing with the music, which is fun.

Of course, there are other tropical plants, such as coconut palm, betel lang, oil palm, and overlord palm in the palm family; Flowers and fruits such as lemon, wild lychee, jackfruit, passionfruit, Garbo fruit tree, etc.

In addition to the national protected plants, the others are all common local tree species and are easy to introduce.

But for visitors to W City, these tropical plants are almost never touched.

If you don't come to Y Province, many plants Ye Han will only hear its name and not see its face.

The tropical rainforests of China only exist in Y and H provinces, and only a small percentage of people come to visit, and probably more than 90% of people have never seen real rainforests.

The construction of a tropical rainforest pavilion close to the original ecology can make up for this regret to a certain extent, so that everyone can better understand these magical tropical plants.

Ye Han adjusted some of the introduced plant varieties, made a list of categories, and submitted an application for the newly added national protected plants.

The model diagram of W04 has also been adjusted, putting the unique strangulation, large slab roots, and hanging gardens in the rainforest into it, making the whole scene more intuitive.

Not to mention anything else, even Ye Han himself is looking forward to it.

*

The next day, Ye Han came to the X City Botanical Garden again and went to the orchid greenhouse.

There are many orchids in Y Province, with more than 900 species, accounting for 71% of the national orchid species, and is known as the kingdom of orchids.

As a result, a dedicated orchid garden was established here.

Researchers from the Chinese Academy of Sciences are responsible for the introduction, domestication and cultivation of wild orchids, including Dendrobium orchid, Wandai orchid, nail orchid, shrimp spine orchid and other species, with more than 200 species

It is an important base for the research of orchid plants in China.

Not only in X City, but also in the Municipal Botanical Garden in K, the capital city of Y Province, there are many kinds of orchids, which make an important contribution to maintaining the diversity of local orchids.

Ye Han followed Director Xu to the orchid greenhouse.

This is the base of the institute for cultivating orchids and is not open to the public.

Most orchids bloom between February and April, and at this time, the botanical garden holds an orchid show, displaying a variety of different colors and varieties of orchids for the public to enjoy.

Nowadays, many orchids are not in the flowering period, but the temperature and humidity can be controlled in the greenhouse, and the flowers can be promoted by scientific research methods according to research needs, and many orchids are still blooming.

When he arrived at the orchid room, Ye Han first greeted researcher Wei Lanyu.

She is responsible for the cultivation of the orchid and the genus Orchid, but she has a detailed understanding of the orchid plant as a whole, which is enough to act as a docent for this time.

The other researchers are also very enthusiastic, and everyone here knows that the retrieval system they use is centered in the Flower Collection.

And they were surprised by Ye Han's youth.

If they hadn't seen it with their own eyes, it would have been hard for them to imagine that such a girl in her early twenties would be the director of the Botanical Garden.

Any of the researchers here were older than her.

Surprised, however, they continued their work, researching and cultivating these precious orchids.

Ye Han looked over from the door, rows of orchids were placed on the rectangular platform, most of them were seedlings that had not yet been divided.

The air is humid and the spray falls from above, between the seedlings and the finished orchids, providing a suitable environment for them to grow.

Ye Han saw that the single garlic orchid being cultivated was not big, it should have just been cultivated, dozens of plants were placed in the same area, and several were blooming.

The pseudobulb at the root is in the shape of a green garlic, so it is called a single garlic orchid.

It is a genus of orchidaceae and a national second-class protected plant.

Ye Han picked up one and looked at it at Wei Lanyu's signal.

Its flowers are pale purplish-red, with slender upper petals that open outward; The lower lip flap is wrinkled around the edges, as if there are several rings of tiny spines around it.

There are spots on the inside of the lip flap, which is not good for the aesthetics of orchids.

Because domestic orchid growers prefer the hollow valley orchid, the feeling of beauty and elegance, while the lone garlic orchid, whether it is the shape of the garlic or the structure of the lip petals, is not so pleasing.

But Ye Han thought it was very special.

'Garlic' is chubby, and two leaves grow one on the left and one on the right, and the color is emerald green. The stalks are not long, the flowers appear to be large, and the petals are stretched widely, which has its own beauty and cuteness.

Wei Lanyu: "This is the single garlic orchid, an endemic species in my country. It is a pity that there are not many people who appreciate it in China at present, and the batch cultivation is mainly for medicinal purposes, which has the effect of clearing heat and detoxifying, relieving cough and reducing phlegm.

"It is very popular in Europe, and Europeans put it on the windowsill as a potted flower, also known as a windowsill orchid, which is suitable for small pots."

Wei Lanyu, as a researcher who studies the single garlic orchid, naturally loves it very much, and can't help but feel sorry for its lack of recognition by the public

。

At present, except for medicinal (), there are few garlic orchids on the market∞ ()_[()]∞ "Come []? See the latest chapter? The complete chapter'() has a certain impact on the cultivation of horticultural varieties such as hybrids.

Wei Lanyu: "The single garlic orchid often grows on the rock wall in patches, and it is very spectacular when it blooms, and I personally think it can be cultivated as an ornamental orchid."

Mr. Ye, what do you think? ”

Ye Han bowed: "It's completely possible." ”

She can imagine the shock of the entire rock wall being covered with lilac orchids, and even if it is not a large bloom, the individual plants have their own ornamental value.

Just like the aesthetics of Europeans, a small one, put on the windowsill to admire.

Wei Lanyu's attitude became noticeably softer, and when she went to fetch a few other orchids, Ye Han used a golden finger on one of the lone orchids.

Du Garlic Lan's voice was soft and glutinous: "I don't like others to call me garlic, it's so ugly." ”

Du Garlic Lan: "Woo, I also want to grow a slender QAQ." ”

Ye Han touched its fake bulb and comforted it softly: "Your garlic is chubby, it's so cute." The petals are slender and beautifully colored. ”

Du Garlic Lan whispered: "Really, really? Garlic... Pretty? ”

Ye Han smiled and said, "Of course, it's very special. ”

Ye Han: "Look, the researcher who trained you also likes you. ”

Du Garlic Lan shook Huahua happily, as if nodding vigorously: "Mmmm! ”

Ye Hanxing's eyes curled: "I will introduce a lot of orchids, do you want to go back with me?" ”

Du Garlic said softly: "Yes!" ”

"Can you put me in the same greenhouse as this one? Together with other Lan Lan. ”

Ye Han touched its fake bulb: "Okay." ”

Nowadays, there are many hybrids in the genus Garlic Orchid, and the number of cultures is also very large, and it has formed a scale.

There is no problem for Ye Han to introduce them.

She followed Wei Lanyu to the front to check on the various orchids.

Apricot yellow orchid, as its name suggests, the orchid is apricot yellow as a whole, including the lower lip petal, there is no variegation and spots, it looks very delicate and ornamental.

It is also known as the golden boy orchid, a national second-class protected plant.

Ye Han thought of the sclerophylla orchid he rescued, and the other party was a bulging pink orchid, like a blowing bubble, also called the jade girl orchid.

The two of them are collectively known as the 'Golden Boy and Jade Girl', which also represents unusual beauty and is very popular in the market.

The one in front is also very beautiful, Ye Han observed it, and said with a slight surprise: "Is this the Mali Po Orchid?" ”

Wei Lanyu: "Yes, it was found in Malipo in Y Province, and it was named directly after the place name. ”

This is a national first-class protected plant and is very precious.

In other words, except for a few species, the others are listed as first-class protected plants.

It is the kind of orchid that people like the most, the flower stalk is erect, longer than other orchids, 30-40 centimeters, and looks slim.

The color is yellow-green, with stripes on the petals and lips, and the color scheme is fresh.

The leaves are dark green, relatively thick, with dotted markings on them, and belong to terrestrial plants.

When the time comes, more than a dozen plants are planted in the orchid area at once, and on the slender and slender flower stalks, the bulging pockets gently sway with the wind, showing elegance.

Wei Lanyu:

"Our project team is cultivating hybrids with the parents of Orchid and preserving its long peduncles."

This is quite an ornamental feature.

Wei Lanyu took a few steps forward and introduced, "The one here is the Caiyun Orchid, and the number is extremely rare. There are almost no complete communities in the wild, and they are all scattered by a few plants, which are endemic to Y Province. ”

Rainbow Orchid.

When Ye Han built the pavilion, this orchid was included in the endangered plant guide, and only Y Province and Myanmar in the world currently have it.

It's so precious.

It is the first time I have seen several species of orchids here.

Wei Lanyu: "Orchid is very resistant and can resist drought, which is rare in orchids. ”

It is not only for the protection of plants, but also for high research value.

After looking at several precious orchids such as the giant petal orchid, the Demon Emperor orchid, the beautiful orchid, and the Wenshan orchid, Wei Lanyu took Ye Han to the orchid cultivation room.

Thousands of glass bottles and media are on display, using aseptic handling and tissue culture techniques to produce orchids in large quantities and then put them on the market.

Tissue culture refers to the isolation of the needed tissues and cells from plants and their regeneration into new plants, which is essentially a form of asexual reproduction.

Although this technology does not help much for diversity, it solves the problem of quantity and cost very well.

As the researchers say, they also want to propagate with seeds, allowing plants to grow naturally and maintaining biological diversity.

However, there is not so much time to cultivate one plant at a time, so you can only ensure the number first.

There are a large number of orchids in Y Province, and the illegal digging is also very serious, and the people here have seen too much, and there may be wild orchids on the mountains behind, and the phenomenon of random digging is very common.

In addition, the high ornamental nature of orchids and the frequent sky-high prices at certain flower markets or exhibitions have contributed to this trend.

Profitable in nature.

And now after tissue cultivation, the cost is greatly reduced, and it is possible to buy a pot of orchids for only dozens or hundreds, and there are many hybrid varieties, which is dazzling.

When the price drops, there are naturally few people digging wild species.

In addition, wild species are more difficult to feed, often born in high mountain forests or rock walls, but artificially cultivated varieties are more likely to produce beautiful flowers.

That's what it means to protect.

Ye Han came out of the cultivation room and looked at so many nationally protected plants in front of him, the lowest of which were all second-class, and this kind of grand occasion could only be seen in Y Province.

Wild orchids are too precious for her to take away so many protected plants, but it is okay to take away seedlings or fresh pollen.

Now Dr. Yu and others have overcome the problem of breeding precious orchids, allowing these orchids to reproduce sexually.

And Ye Han used it in exchange for Darwinland seedlings.

When she took out the flask, all the researchers gathered and looked excited.

"It's the famous Darwinland."

"It's really cultivated!"

Darwin orchid is native to the African island of Madagascar, and is recognized as an orchid that is difficult to introduce and cultivate, and it is also a well-deserved star plant in every international orchid exhibition, and many people do not see it once in their lives.

And here, there are actually five seedlings!

And each one is very fresh, and has already grown two or three leaves, which will soon be divided into the test field.

This exchange was undoubtedly a success.

Ye Han will also introduce a variety of national protected orchids to prepare for the creation of an orchid area.
