After nearly two months of land reclamation, a large number of construction personnel and large machinery and equipment were mobilized, and the gravel and weeds on the barren mountains were basically cleared.

The dead vegetation was removed, the land was largely renovated, and the mountains were covered and melted by the heavy snow of the previous two days, and the snow water flowed over the slopes, which amounted to a hearty irrigation and laid the foundation for the germination of the remaining grass seeds and trees.

Ruixue Trillion Year.

When the weather was clear, Ye Han went to check with Wang Hongnian and others.

You can clearly feel the changes in the mountain, all the stones and waste on the surface are cleared, the compacted soil becomes loose, and the two mountains that were not able to be climbed at first are much smoother, and you can climb to the top directly.

Generally speaking, the effect of land reclamation has been achieved.

Ye Han looked around: "Brother Wang, you and the workers will check it carefully, and if there is no problem, it will be accepted next week." ”

Wang Hongnian looked at the soil: "Good principal." ”

There is a complete set of standards for acceptance, which both parties are familiar with, and there is no need for Ye Han to bother.

However, the newly cultivated land is a little barren, and it is necessary to apply organic fertilizer for long-term maintenance, and the irrigation of plant nutrient solution is also indispensable.

The area of 1140 acres will be built in four times according to the capacity of W04, and the planning will also take time, and it will not be completed in a while.

After the temperature rises in March, Ye Han is ready to green and reclaim the first hill first.

It is expected to introduce hundreds of native tree species and tens of thousands of saplings; On the back, maple and red maple are planted to create a dense forest and a beautiful autumn scene.

It's a huge project.

According to the scan map of the system, the first mountain closest to the tea plantation has the largest surface area of 423 acres.

Removing mountain trails, cliffs, and other landscaping, the green area is about 380 acres, with a forest coverage rate of 90%.

Specifically, it is mainly to create evergreen broad-leaved and deciduous mixed forests and coniferous forests, with a variety of shrubs, to achieve the purpose of afforestation.

The area of saplings is small, and 300-500 trees can be planted per acre, which means that the demand for saplings is 12-190,000 trees, which is huge.

Almost ll more than all the plants in the current flower collection combined.

The price of local saplings on the market is not high, such as camphor saplings with a DBH of 3-4 cm, which are sold for less than 30 yuan.

However, planting all of these slender saplings will appear very sparse and have a long growth cycle.

Even if the plant nutrient solution stimulates cell activity and promotes rapid growth, it is unlikely to grow into a stout tree in a year or two.

With this in mind, Ye Han plans to introduce saplings with a DBH of more than 8 cm, and at least 30% of the finished trees.

As a result, the cost is high.

Due to the increase in land area, about 200 saplings can be planted per acre.

The price of a single high-quality seedling is more than 60 yuan, and the unit price of the finished tree is at least 600-800 yuan; The density of Acer jaw seedlings remains unchanged, and the unit price is calculated according to 100 yuan/tree, and the preliminary calculation is ......

Ye Han roughly estimated that it would cost at least 12 million to 15 million.

This is just a mountain, plus the other two, and the introduction of trees alone will cost 30 million to 40 million yuan.

Clearing land for afforestation is indeed not an easy task.

At this time, there is still one month before March, and Ye Han is ready to start bidding from now on.

It is divided into two parts, native tree species and maple trees, both of which are large orders with an amount of up to 6 million.

I believe that after making a request, the gardening company will be able to give a good offer.

In addition, valuable tree species such as dove tree (first grade), yew (first grade), Putuo hornbeam (first grade) and other valuable tree species can also be introduced.

The dove tree, which existed in the Cenozoic generation more than 6,000 years ago, is a unique species in China.

When it blooms, the flowers of the tree resemble a white dove that spreads its wings and flies, and it is also called a pigeon tree, which is highly ornamental.

Ye Han has seen it in the park, and it is very beautiful.

Yew is an ancient tree species left over from Quaternary glaciers.

When the fruit is ripe, the small red fruits hang all over the branches, resembling 'acacia red beans', hence the name yew.

All species of the genus Taxus are first-class protected plants and are extremely valuable.

Not to mention the Putuo hornbeam, the 'only son of the earth', there is only one wild 'husband and wife tree' in the world, which is so precious that it is indescribable.

They can be planted on both sides of the winding trail for visitors to see.

Or it's not bad to set up a separate ornamental garden for rare tree species.

Ye Han asked Wang Hongnian to release the bidding news, and first compared the quality and price of the seedlings.

As for the specific combination and number of tree species, I believe that these experienced horticultural companies will give the perfect quotation and plan.

At that time, the final plan can be determined by adjusting the stereogram of W04.

In early February, the patent application of Dr. Yu et al. was successfully accepted and the preliminary examination was completed.

Although it takes a long time for the patent to be reviewed, according to a series of materials submitted, it is enough to prove the true validity of the patented technology of the Huajian Research Institute's 'research and batch cultivation based on the sexual reproduction of rare orchids'.

Relevant academic papers have also been published in national journals.

Dr. Yu hid the core technology, shared the rest of the cultivation process without reservation, and published the experimental results and diversity reports in irreproachable detail.

At a glance, people in the industry know the great scientific significance behind this achievement.

In an instant, one stone stirred up a thousand waves, triggering a shock in the entire academic field, including the Institute of Botany, Chinese Academy of Sciences.

Countless people have set their sights on the flower set.

After breaking the Guinness World Record twice in a row and successfully cultivating the country's second silver silk top peony, the other party once again delivered terrible results.

Sexual reproduction of rare orchids! Or in batches!

Doesn't it mean that the endangered orchid plant in the country has been saved?

What a significant result of the research!

It is true that due to the natural characteristics of orchids, the number of sexual reproduction cultivation is at most a few l, ten or hundred, far less than the scale of tissue culture from 1 to 10,000.

But the purpose of the two is completely different.

The latter is to bring down the price, let orchids enter thousands of households, reduce the value of wild orchids in the hearts of the public, and better protect them.

And the flower collection is to maintain the diversity of the species, so that it is endangered

Plants are multiplied and passed on.

The quantity is not important at all, the meaning of inheritance is the most important!

What shocked everyone even more was that the problem that plagued the world was not only broken by the researchers of Hanamaji, but also in just one year!

It's horrible.

"Really?"

"How is it so fast?"

"Speed... Comparable to the speed of light. ”

"Not really. There have been many people who have studied it before, but it is too difficult to give up, and the results are there. ”

"We've only been organizing tissue culture for seven or eight years, and sexual reproduction has actually come out?"

"If patents are true, then we are ahead of the world."

"Which team is so good? What's the matter? ”

"I specifically searched for the main researcher, Yu Siming. Born in the Chinese Academy of Sciences, he was poached to work in the Institute of Country M with a high salary less than two years after graduation, and has published many academic papers, including two in SCI. ”

"That's really amazing, it's a genius."

……

SCI (Science Citation Index), EI (Engineering Index) and ISTP (Science and Technology Conference Proceedings Index) are the world's three leading scientific and technological literature retrieval systems, and are internationally recognized as the main retrieval tools for scientific statistics and evaluation. ①

Being able to publish a paper in a SCI journal is definitely the top academic paper.

Soon, Ye Han received inquiries from Professor Ye Huaxi from the National Botanical Garden, Director Xu from the Y Provincial Tropical Botanical Garden, Director Liang of the Forestry Bureau, and Dr. Hou.

Ye Han replied to the messages one by one: "The research results are true.

However, at present, only the batch cultivation of Apricot and Sclerophylla has been completed, and other orchids are still being studied. ”

After all, time is limited, and it takes just over two months to obtain wild samples.

Moreover, the different species of orchids, the ratio of the required medium is also different, and only the seedling cultivation brought by Ye Han from Y Province has been completed, and no follow-up research has been conducted.

When the orchid blooms in March and May, the sample size is abundant enough, and more varieties will be cultivated.

It is believed that the availability of orchid seeds will also be greatly improved after irrigation with plant nutrient solution.

After Ye Han's confirmation, the two major research institutes of the Chinese Academy of Sciences suddenly couldn't sit still.

In particular, the Tropical Botanical Garden of Y Province, which is located in an area that is native to wild orchids, has a huge responsibility for the conservation of rare orchids.

With this technology, why worry that the wild orchid population cannot grow!

They are in great need of this technology.

At present, the patent is still under review, so it is natural that the core technology cannot be disclosed to prevent someone from fraudulently claiming the research results.

However, after discussing with the institute, Director Xu planned to visit the flower market in March and signed an agreement with the other party to transport orchid seedlings.

By purchasing orchid seedlings cultivated by the other party at a high price and placing them in the wild environment to adapt, the goal of saving endangered orchids is achieved.

Ye Han was happy to see this come to fruition and proposed to reach mutual assistance and cooperation between the two sides.

/>

The Y Tropical Botanical Garden sends samples of wild orchids (seeds, pollen, cuttings, etc.) to the Flower Collection, and the Flower Collection gives a certain number of orchid seedlings to the other party.

Hit it off.

In this way, different genes can be obtained from multiple samples

It is good to maintain diversity, select the best of the best, and cultivate the best quality orchids.

When Ye Han went to the [Orchid Secret Realm] to check the growth status of the transplanted orchid and the orchid, the voice of the system sounded in his head: "Congratulations to the host for completing the collection task, please receive the super gift package." ”

Ye Han was stunned for a moment, and then clicked on the light screen panel to view the information.

Name: Yehan

Gender: Female

……

Bound to the Botanical Garden: Flower Set (100% equity)

Area: 2190 acres

Collection process: 1010‰

Rescue of endangered plants: 102 species

Ancient trees rescued: 32

Available Points: 796

After more than a month, more than a dozen orchids that were originally under cultivation were successfully promoted to S-level plants, and the collection process exceeded 1000%.

At the same time, maple trees such as Acer pentaphylla, Acer miaotai and Acer sturgeon are growing well, and the number of endangered plants rescued has increased again, exceeding 100 species.

It can be described as a double happiness.

It's done.

Finally... It's done!!

With indescribable excitement in his heart, Ye Han closed his eyes and recalled the bits and pieces along the way.

When I first took over the Nanshan Botanical Garden, not to mention meeting the collection standards, even the plants in the garden could not be saved.

In three months, the first S-class plant finally appeared in the flower set, the Cruz royal lotus, followed by the lotus pond's lotus lotus.

With the continuous opening of the landscape area, more and more plant species have been introduced, and S-class plants are gradually increasing.

Ice lamp gyokuro, aloe vera queen, raw stone flower in the glass flower room; peach trees and ginkgo trees in the ancient tree area; the ancient osmanthus tree in the garden of cinnamon; Epiphany Kao and two-color marvisa in the Rare Plant Museum......

Up to now, a total of more than 120 S-class plants have been collected, nearly 400 A-class plants, and the total number of plant species exceeds 2,500!

She also completed 1000% of the tasks of the system.

Ye Han opened his eyes and looked at the pop-up dialog box: [Do you want to receive the super gift package? 】

Taking a deep breath, I was somehow a little nervous.

She asked the system, "What's in the package?" ”

System: "The host will be known when it is opened." ”

Ye Han: "Okay. ”

Ye Han froze and clicked on the golden icon.

[Congratulations to Ye Han, the host of Plant Protection System No. B544, for completing the collection task.] 】

Your reward is:

1. Obtain the right to decide the development of the botanical garden, and the system will unconditionally cooperate with your decision.

2. The points for redeeming items will be halved and an additional reward of 3000 points will be obtained.

3. You can choose one product as a lifetime exchange-free product (the quantity is automatically set according to the scale of the botanical garden).

4. Open the plant germplasm trading interface, which can be purchased with points.

Ye Han swept them one by one, her heart beating faster, this was much more generous than she imagined!

The first reward system was said before, with mental preparation.

The first half of the second reward was also mentioned, but the extra 3,000 points undoubtedly made her excited.

3000 points with the benefit of halving the points is simply against the sky.

W04 costs 150 points to use once, and 3000 points can be used 20 times!

It only takes 4 times to reclaim the barren mountain, which is more than enough.

The third reward, choosing a product to redeem for free, is a bonus.

Ye Han will definitely choose plant nutrient solution, which is a necessity.

The number of hundreds of thousands of plants after afforestation in the barren mountains between flowers requires about 3 bottles of plant nutrient solution per month.

50 points per bottle, 150 points a month, 1600 points a year.

With this benefit, it is as much as possible to be exempt.

The pressure suddenly became a lot less, no, it should be said that there was no pressure.

And the last one -

Under the gesture of the system, Ye Han clicked on the [Trading Entrance-Plant Germplasm Zone] in the lower right corner.

The translucent interface shows the different classifications of plants, with a wide variety of seeds and flower seedlings.

Not only domestic, but also foreign, and even extinct plants?

Is it a mistake?

Among them are the names of plants on the extinct plant staircase in the Science Museum.

System: "You read that right, host. ”

System: "We don't just collect plants from one era, but the whole age of the planet." Cambrian, Ordovician, Silurian, Devonian, Carboniferous...... Each epoch of plant types is collected. ”

Ye Han: "But plants in different periods have different climates and adaptation conditions, and they-"

It is impossible to coexist in the same time and space.

She paused for a moment, realizing that she had overlooked a question.

The Milky Way is not like Earth, which has only one home.

System: "We have thousands of artificial planets, just as many as Earth's satellites. Each planet has a different environment where plants and animals can evolve. ”

Ye Han had already seen the power of Galaxy Technology, and he was not surprised by this.

Judging by the number of the B544, it is known that there is more than one system.

Ye Han: "That host who is in the same era as me?" ”

System: "Scattered in different countries with a certain time difference.

We don't want to be remarkable, and although we can tamper with the brainwaves of hundreds of millions of people, the instructions from our superiors are: reduce intervention. ”

Ye Han didn't know what to say.

I wasn't surprised just now, but when I heard this, my heart was still tight, it was a fear of the unknown.

Fortunately, since taking over the botanical garden, I have been exposed to too much high-tech, and it didn't take long for me to adjust my mentality.

Ye Han looked at the trading interface on the light screen again.

The seed exchange points of extinct plants are very high, starting from 5000 points, and the plants before the Quaternary are simply black and cannot be exchanged.

She thought it was too exaggerated to explain it.

Ye Han has no idea of saving extinct plants for the time being.

Even if you finally save up 5,000 points to redeem a tree, what can you do?

There is only one tree in the world, and the dioecious varieties cannot even pollinate and reproduce, and due to environmental changes and other reasons, there is a high probability that they will be extinct.

She can't be saved by herself

Target.

Ye Han looked at the interface, the rarer the plant seeds, the higher the exchange points, and the seedlings/seeds of rare and endangered plants are basically above 100 points.

Then she saw the categories she had collected.

Garlic orchid seedlings (S grade): 10 points/tree

Seedlings of Mali Po Dou (S grade): 10 points/tree

……

East China Sea Wave Flower Seedlings (S Grade): 10 points/tree

Real Lavender Seeds (S Grade): 10 points/ton

10 points/ton...?

That's too low, isn't it?

If you look closely, it turns out to be discounted points.

System: "According to the trading rules, gene providers enjoy a 1% discount. ”

Ye Han smiled: "Very humane regulations." ”

It's just that the single garlic orchid, the Ma Li Po Dou orchid... Isn't it the S-class that was just upgraded last month?

Is it a clone of your own strain? It's so fast.

And lavender is A-grade, not S-grade, she remembers it very clearly.

System: "The plants exchanged at the interface maintain the diversity of species, and the host can rest assured."

The level increase is due to the fact that under the cultivation of Galaxy Technology, hundreds of breeding have been carried out to obtain the best quality S-grade varieties. ”

Ye Han was puzzled: "But... Only one sample is collected for each gene extraction, how to breed it? ”

System: "The genetic simulator predicts the gene editing sequence, gets a large number of plants, and then pollinates them naturally, reproduces them on a large scale, and selects the best quality batch." ”

Ye Han was about to ask a question, but the system replied in time: "The host may feel that a month is too late." But time is relative, under different gravitational forces, 100 years = 1 day. ”

Ye Han had nothing to say.

Galaxy Technology is indeed beyond her imagination.

However, having this trading system means that she can exchange very low points for the plants she collects!

The rare orchid plant samples needed for the laboratory and the seeds of the 1,000-acre lavender flower field that will be built are now available.

Other rare tree species can also be exchanged here to enrich the variety of plants in the flower collection.

This trading channel is amazing!
