A few days ago, the staff dormitory of the botanical garden was finally renovated thanks to the efforts of the decoration team.
Although it is a simple decoration, Ye Han did not save on materials. He chose environmentally friendly materials. The formaldehyde content is far lower than the national standard, and the house can be moved in after ventilation for a period of time.
The part-time staff were laid off a week ago.
Before leaving, many people left their contact information to Ye Han, hoping that he would notify them if they had any needs. It seemed that they were quite satisfied with this job.
As for the two full-time employees, Wang Hongnian and Liu Chunling, they also took two days off under Ye Han's arrangement - they had been too tired recently and they deserved proper rest.
This situation resulted in Ye Han being the only one left in the huge Nanshan Botanical Garden, making it more convenient for her to carry out experiments.
When the sun set and the sunlight was no longer glaring, Ye Han came to the entrance of the botanical garden with plant nutrient solution.
These 'hot spring pools' had been cleaned half a month ago. The water was crystal clear, with ripples and a few fallen leaves floating on the surface. Combined with the rockery and green trees next to it, it created quite an artistic conception.
The rushing waterfall hits the bottom of the pool, splashing water with a clear buzzing sound and splashing water droplets. It is hard to believe that it was so dirty and messy a month ago.
Ye Han walked over the waterfall to the largest pool and roughly estimated its volume.
The pool is about 130 cubic meters, about half a meter deep, with a difference of 10 centimeters between the water surface and the ground. The water volume is about 105 tons, which is just suitable for diluting 1 ml of nutrient solution.
Ye Han took out the prepared test tube, carefully poured the plant nutrient solution into the 1ml mark, placed it in front of his eyes and shook it gently.
The clear almond eyes reflected the emerald green color, as if reflecting the concentrated scenery of lakes and mountains. The liquid was pure and transparent, and did not stain the tube wall at all during shaking. The texture was viscous and the green color was rich. It looked like flowing amber under the light, which was very beautiful.
At the same time, a faint fragrance floated out from inside as it shook, as ethereal as clouds and mist.
The smell is very special, as if it contains the freshness and endless greenness of grass and trees after the rain, which makes people think of the grass and birds singing in February. It makes people feel relaxed and happy just by smelling it.
Ye Han looked at the crystal clear liquid in front of him. It didn't look like plant nutrients either visually or smelled like it. Instead, it smelled like a perfume carefully developed by a big-name company. It smelled particularly good.
Soon, the test tube tilted, and the drop of viscous liquid fell into the pool, like a drop of ink blending into the sea, disappearing without a trace in an instant.
Ye Han looked at the nutrient solution that was completely integrated into the water. With such a huge disparity in ratio, it was difficult to find any trace of it even with a magnifying glass that was a thousand times stronger.
I just don't know if the effect is as magical as described in the introduction.
She half-knelt down, filled two watering cans with water, and carried them to the flower area.
Flower areas such as the Peony Garden, Chrysanthemum Pavilion, and Crape Myrtle Garden are all vacant, with only seven or eight pots of transplanted flowers and bonsai placed in a dark place to avoid being burned by the scorching sun.
Although these plants survived thanks to Ye Han's treatment, it was obvious that they were not in good condition. They were like patients brought back from the emergency room, their vitality was severely damaged. Even if they were moved to a more comfortable environment, they would need time to recover slowly.
Ye Han put the watering can aside and checked the soil moisture and recovery status first.
In summer, the temperature is high and the sunshine time is long, so the water of plants evaporates quickly. Even if you have just watered them two days ago, the soil will be dry. For some plants with high water demand, in addition to watering, you also need to spray the branches and leaves every morning and evening to ensure their humidity.
Ye Han lightly loosened the soil for several potted plants, cleared away the weeds and dead leaves growing around them, and picked up a watering can to water the plants.
A thin stream of water pours into the flowerpot and accumulates into a shallow puddle above the soil. Under normal circumstances, it must at least wait for complete penetration before it can be slowly absorbed by the roots of the plant.
However, this time, all the plants seemed to be experiencing a severe drought, absorbing water from the soil at an almost crazy speed, even making a 'sizzling' sound as they absorbed water.
This feeling is just like a homeless person who hasn't eaten for several days encountering a table of delicious food. He doesn't even need to chew and just wolfs it down.
Anyone can feel their thirst for plant nutrient solution.
One pot after another, the two watering cans were soon empty.
Based on the usual usage, I watered about 10% more than usual.
However, time - Ye Han checked his phone and it was more than twice as fast as usual.
This is the fastest watering speed in history.
Just as Ye Han put down the kettle and prepared to check the soil moisture, he only saw pots of almost dry soil.
When you touch it, it feels almost the same as before watering.
The absorption rate of these plants is simply amazing.
Ye Han was stunned for a moment, then took some clean water to wet the soil, and at the same time sprayed the leaves of plants with high humidity requirements.
Perhaps there was some residual nutrient solution in the spray bottle. In the spraying mist, she heard a subtle "sizzling" sound, like a hungry baby sucking breast milk.
The originally dull leaves were washed to a sparkling color, and the tiny water droplets on the surface were instantly absorbed. Then, the leaves were shaken happily, looking forward to the arrival of the next dew.
…
During Ye Han's watering process, the plant nutrient solution had slowly begun to take effect.
Starting from the root system of the plant to the stems, leaves, and diverging leaf veins, a light green light flashes across the surface, like a high-speed moving light spot, rapidly spreading along the plant's trachea, sieve tubes and other transport channels to every cell, carrying out photosynthesis and metabolism at an extremely fast speed.
At the same time, in a place Ye Han couldn't see, the roots buried in the soil were undergoing secondary growth.
The taproot is gradually growing longer and thicker, and more lateral roots and adventitious roots are growing. They are deeply rooted in the soil, maximizing the absorption of surrounding nutrients and providing nutrients for plant growth.
Everything happens imperceptibly.
Ye Han put down the watering can and looked at the plants in front of him. Most of them still had sparse branches and leaves or looked a little wilted.
However, something seems to have changed.
Although no conclusion could be drawn in a short period of time, she keenly felt that their mental state had improved a lot.
It was a kind of vitality that came from within, like a hunchbacked middle-aged man trying to straighten his back. Even though the appearance had not changed, his spirit had become very different.
Ye Han took out his cell phone and took pictures of these potted plants one by one.
Observation with the naked eye is not as intuitive as images. Perhaps in three to five days, or a week, when she compares them with photos, she will be able to see obvious changes.

After preparing the potted plants, Ye Han used a water pump to connect the irrigation device to draw water from the pool to irrigate the trees, shrubs, and bamboo forests on both sides of the road.
Hundreds of garden plants were baptized by the nutrient solution. Their absorption capacity was stronger and their demand was greater. There were sizzling sounds everywhere, cheerful and enthusiastic. Even the water droplets spilled in the public areas were not spared, and they scrambled to grab them. That little bit of moisture was quickly absorbed, like plucking feathers from a passing goose.
The effect is also significant.
The well-developed root system extends deeper and wider into the soil. The thoroughly watered soil turns from damp to slightly dry in just a few minutes. Several deciduous trees with strong vitality and good growth soon show vitality visible to the naked eye - the dull leaves turn into bright green, and they seem to be covered with a layer of light green film, glittering in the afterglow of the setting sun.
After watering these widely distributed trees, Ye Han's body was also wet, but the mark quickly evaporated under the high temperature, leaving only a little fragrance of grass and trees.
Ye Han raised his hand to tidy up his sweaty hair, then sat down to rest for a while. The hot weather was indeed a bit unbearable.
Fortunately, as the sun sets, the temperature gradually drops, and the gentle night breeze finally brings some coolness to the summer.
Ye Han walked to the lake with the nutrient solution.
The artificial lake has a huge body of water, and the lake surface is sparkling everywhere as far as the eye can see. If you look at it for too long, you will easily be dazzled by the orange color of the lake.
She climbed onto the wooden plank road and sprinkled a few drops of sticky nutrient solution on the densely populated lotus flowers, and the same was true where the Victoria amazonica was.
As the green color dissipated in the lake, the clear water surface soon returned to silence.
Ye Han continued walking along the plank road. The round lotus leaves swayed in the wind. A few flower buds that had not yet bloomed stretched high out of the water. There was a half-pond of lotus flowers that stretched as far as the eye could see.
She didn’t know if it was her illusion, but when she passed by, she felt that the lotus fragrance seemed a little stronger than before.
After watering all the plants in the garden, Ye Han came to the ancient tree area carrying a small bucket of water.
After a busy night, this was her last job.
The 400-year-old peach tree was still as rotten as what we had seen before, with cracked bark and a hollow interior. Even with automatic sprinkler equipment installed on its top and inside the trunk, and painstaking maintenance, it could not stop its decay.
After experiencing so many years of wind and rain, the peach tree has not only been damaged in appearance, but its own physiological functions have also been weakened, and its absorption capacity is much lower than before.
Methods such as loosening the soil, fertilizing, and improving the soil that are suitable for ordinary plants cannot save it at all. Anyone with a discerning eye can see that it can only rely on external objects to barely maintain its vitality and survive.
Ye Han carried a bucket into the protective fence and slowly poured water around the roots.
She watered slowly and carefully, adhering to the principle of small amounts and frequent applications, but she did not dare to water too much and soon stopped.
As an ancient tree that has survived a long time, any disease, insect pest or yellowing leaves may be fatal, so watering must be moderate.
If the roots were soaked in water and rotted, she would have no way to deal with it.
However, the peach tree did not appreciate it. The nutrient solution was like a dying patient suddenly taking an elixir, but unfortunately it was gone before it could even taste it. How could the "tree" not be upset?
Fortunately, Ye Han couldn't hear what it said, otherwise he would definitely hear angry "swearing" with a domineering tone.
After all, he has lived for more than 400 years.
It has been planted since the Ming Dynasty until today, and has experienced so many changes of dynasties, and feudal ideas are deeply rooted.
After taking care of the peach tree, Ye Han watered four other ancient trees, including the ginkgo tree and the Podocarpus. When he was done, he was so tired that he could not even lift his arms. His face turned red and his breathing became rapid. He sat there to rest for a long time.
Phew, it’s finally done.
She looked at the trees that were irrigated with nutrient solution one by one, her lips curled up slightly, her heart filled with a sense of accomplishment of completing the task, and even her physical fatigue seemed to dissipate a lot.
As for the effect of the plant nutrient solution, it will take some time to see.
However, with the example of water purifiers, Ye Han believed in its effectiveness.
