Dr. Hou and the other two perfectly reached a cooperation between the institute and Huajianji, and won the latter two most precious new varieties of the institute. After receiving Ye Han's permission, he was not polite in collecting.

He had long been eyeing this rare giant overlord lotus and happily directed the two assistants to take samples.

Wang Lian is worthy of being the "king of aquatic flowers". It bears fruits in September. The ripe fruit contains hundreds of seeds, with amazing yields and edible.

However, this king lotus is so rare that a seed will definitely be preserved without falling.

After Wang Lian was blooming, Ye Han put a breathable white net bag under the flower stalk that was about to fall. When the fruits matured and fell off, they could fall into the net bag and collect them perfectly.

After getting it, she counted and found that there were more than 700 seeds from this king lotus, which was astonishing.

Dr. Hou was surprised when he saw it.         There are rare in so many quantities, which further proves the excellent quality of this Wanglian.

He carefully selected 100 seeds and asked two graduate students to put on waterproof clothes. With the help of Huajianji employees, he picked the "small balls" from Wang Lian's underground rhizomes.

"You must be careful. Try to stay away from the roots when collecting, and move carefully... Alas, slower, slower, pay attention to the techniques..."

Dr. Hou walked around the shore, commanding anxiously, wishing he could get into the water himself.

These small balls are isolated from the mother's home. They have the mother's home gene and are the easiest way to reproduce.

As long as the techniques are appropriate and some maintenance is performed after removal, the body will not be damaged.

The seeds are the natural reproduction of Wang Lian and are the descendants of the mother.

Two ways of reproduction are essential.

After completing the most important part, Dr. Hou also asked them to collect leaf samples, rhizome samples, flower stalk samples that are about to wilt, water samples of artificial lakes, and other samples of Wang Lian... It can be said that no one will fall into it.

The two graduate students were so busy that they were sweating profusely. After collecting various samples, they were so tired that they could hardly straighten their waists.

The various samples they extracted were dozens of them, which can be said to be the most detailed one.

Dr. Wang went to the warehouse of Huajianji.

He carefully sprayed the two selected lotus pods to keep the surface moist, then carefully wrapped it with plastic wrap, and put it in a freezer that he carried with him to seal it.

Lotus seeds also need to be taken.

According to previous discussions, he was able to take away two lotus pods and one-fifth of the lotus seeds.

Each double-headed lotus pod has about 50 lotus seeds, and 6 plants are nearly 300, so he needs to choose 60.

With an attitude of striving for excellence, Dr. Wang carefully selected one by one with gloves, constantly compared it, peeled out one and put it down, picked it up again after a while, and repeated it.

It took two hours to complete the selection.

Dr. Wang raised his head from the table, his eyes a little congested: "Sorry, I'm a little obsessive-compulsive."

The main reason is that these lotus seeds are full and round, and he can't confirm after picking them all, so he simply makes up his mind and blindly choose.

Otherwise, I don't know when I will pick it.

Ye Han smiled slightly: "...It doesn't matter, it's understandable."

But I was thinking: The researchers were indeed very patient.

If it were her, she would definitely not have the patience.

After the two doctors and assistants finished sampling, it was already completely dark.

This time I got a lot of rewards and almost all the sampling bags I brought were used.

Dr. Hou looked at Ye Han and stopped talking, but finally left his face: "Well, when I came last time, I saw that the succulents in the flower room were well-raised. Can we pick some leaves and go back for leaf transplanting and breeding?"

Ye Han: "..."

She thought about the succulent situation: "It's OK. If the researcher needs it, the future division can also be taken away by part of the tissue for scientific research."

After two leaf insertions, the succulent has grown from 100 pots in the early stage to more than 400 pots, filling the glass flower house with a full fill. Once inside, it seems like entering the real succulent kingdom, and the succulents are everywhere in sight.

With other potted plants, about 500 pots of plants are cultivated in the glass flower room, and the number of them will make it look a bit crowded.

In this way, it is better to allocate some resources to the research institute to establish good relations.

With permission, the two doctors left with a generous 'trophies' with a smile on their faces, and Huajianji is about to usher in two precious new varieties.

Water lilies are roughly divided into two categories: tropical water lilies and cold-resistant water lilies.

Ye Han introduced tropical water lilies before, such as Egyptian blue water lilies, Indian red water lilies, etc., with a flowering period from June to September. When the weather is cold in November, it will enter a dormant period, and the wintering temperature cannot be lower than 10 degrees, otherwise it will be frozen to death.

As the name suggests, cold-resistant water lilies are better for cold resistance. They can pass the winter after 0 degrees or above, and the short-term freezing period will not affect their vitality.

However, whether it is tropical water lilies or cold-resistant water lilies, the flowering needs a suitable temperature, which can be about 15-25 degrees.

The temperature is right now in September. It is best to put them in a greenhouse after the weather gets cold, so that they can be extended and more conducive to their survival.

When the experts from the institute arrived, they focused on testing the water quality of the artificial lake.

Water lilies must live in an environment with clean water, suitable temperature, sufficient sunshine and good ventilation, otherwise it will affect its state.

Even if fertilizing during the growth period, liquid fertilizer cannot be applied. Instead, dry cake fertilizer should be buried in the soil to avoid contaminating water bodies.

In short, water quality and temperature are very important.

The test is very simple. Use professional tools to test and the results can be produced on the spot.

However, the test results surprised the two experts.

Because the water is too clear and too clean, it is no exaggeration to say that it has reached the standard of direct drinking water.

After testing, the tds (i.e., soluble total solids, mg/l) in the artificial lake are 50, and the domestic tap water standard is tds<1000, and most areas are between 200-300.

The higher the tds value, the more impurities are contained in the water.

The artificial lake's TDS is less than 50, which means it is extremely pure and almost reaches the level of mineral water.

It would be fine if it was a pool at the entrance, after all, the water volume was small and you could change the water frequently; but this was an artificial lake with a capacity of tens of thousands of tons. It was really rare that such a huge water body could maintain such a clean state.

Not to mention water lilies, any aquatic creature will like this environment.

At the same time, the temperature control system and light control in the glass flower room also amazed them. Such a luxurious environment can definitely meet the growth needs of orchids.

After a series of evaluations, the ecological environment of Huajianji far exceeded the estimates of the two experts.

When they heard that the exhibition greenhouse was being built here, they were even more shocked.

Oh my God, the private botanical garden that has just opened for two months is going to build a 2,000-square-meter greenhouse?

What a big deal.

The two experts really didn't expect that a private botanical garden would have such courage and financial resources.

I believe there are many opportunities to cooperate in the future.

...

The next day, 100 cold-resistant water lilies "Cangjin" and 5 precious "Central African Comet Orchids" officially entered Huajianji.

Among the 100 high-quality water lilies, the other 90 are just rhizomes with new buds. They need to be planted first before they can be gradually moved into artificial lakes and exhibition greenhouses.

As for the five "Central African Comet Orchids", Ye Han specially made a place in the glass flower room and built a special room for them. After the exhibition greenhouse is completed, they will be moved into the greenhouse and carefully cultivated.

Expert Guo Yuanjiu told Ye Han about precautions for breeding orchids: "These Central African comet orchids are grandchildren of the 'Darwinite orchids', which have improved the characteristics of the epiphytic orchids that their mothers originally grew on tree trunks or rocks. They do not require wooden stakes and can be directly raised in flower pots.

Its flower distance is not as long as the Darwinland, which makes it easier for it to pollinate, and to some extent, the probability of survival is higher."

"But this orchid is very sensitive to temperature and humidity. The temperature must be kept above 25c and above 80% all year round, otherwise it will not survive.

I suggest you install a temperature and humidity detector next to the flower pot and make corresponding controls based on the temperature and humidity."

"Be careful about the amount of watering, not too much. If too much, the orchid will grow worse and the roots will easily rot; do not spray it on the leaf core, which will easily cause rot; the humidity is not enough to be lower than 70%, and the leaves will easily curl and turn yellow and dry..."

Guo Yuanjiu explained in detail, obviously not very relieved: "If you want it to bloom, you must first provide it with enough nutrients. This process often lasts for several years and you must have enough patience...

Anyway, orchids are very delicate, so you must take good care of them.”

Ye Han had seen the relevant introduction on the information and wrote it down skillfully, but he still nodded frequently when the other party was explaining it, listening very seriously, which made Guo Yuanjiu very satisfied.

Raising orchids requires this attitude, such as humility, patience, no arrogance or impetuousness, and always maintain a good attitude, otherwise it is easy to give up halfway, and orchids will not survive due to poor care.

well.

Orchids are indeed delicate and difficult to raise, and the same is true for orchids in the wild.

In the National List of Protected Plants, there are the most orchids of the orchid family.

Orchid (all species) are secondary protected plants or above; except for Paphiolenum (all species), the hard-leaved Paphiolenum is a secondary protected plant, and the rest are all national first-class protected plants...

Now the country has completely banned the mining of wild orchids and has taken various measures to maintain their living space.

Thinking of this, Guo Yuanjiu couldn't help but feel emotion.

Fortunately, the introduction and domestication of wild orchids and hybridization have been underway, and botanical gardens have been built one by one, working together to continue their genes. Now, some precious new varieties have been successfully cultivated.

Everything will slowly get better.

I hope Huajianji can take good care of these precious orchids so that their genes can be passed on.
