The Creature Replica has been successfully upgraded, and the number of times it can be reproduced has also been increased to 16.

The replica machine was in place, and Chen Cheng immediately called up the system and prepared to start the experiment.

He put the bud of a wild orange in front of him, and the system immediately scanned a 3D image of it.

[The content and composition of somatotropin in the calculated sample are being tested]

Phyto-growth hormone is a general term for plant growth hormone. Generally speaking, the main plant growth hormones that have been discovered so far are auxin, gibberellin, cytokinin, and abscisic acid.

Auxin relaxes plant cell walls, promotes cell growth, and affects the phototropic and backlight growth of stems and leaves.

Gibberellin can significantly promote plant growth, prevent flower and fruit shedding, and improve plant fruit setting rate and yield.

Cytokinin can promote plant growth, increase the sugar content and alkaloids in plants, and improve plant immunity.

Abscisic acid can promote the shedding of plant flowers, leaves and fruits, and effectively inhibit plant growth. It is generally secreted when plants need to store nutrients.

[The test and analysis are complete.] The content of somatotropin in this sample accounted for 7.5% of the liquid content, which is a high level]

[The main components of auxin are: auxin 27%, gibberellin 18%, cytokinin 31%, abscisic acid 4%, mineral operanin 20%]

"Mineral Operaton?" Chen Cheng was surprised.

He had never heard of the hormone name.

[Yes.] According to supercomputer analysis, the mineral operation hormone is an undiscovered plant growth hormone that is found in some plants that grow in poor soil environments.

"An undiscovered plant growth hormone?!"

Chen Cheng was shocked, feeling that he had discovered a new world!

[The main function of mineral operant is to transport the excess minerals and trace elements absorbed into the body by plants to the leaves, fruits and other parts that will be detached regularly, so as to reduce the accumulation of minerals in the plant body and ensure that the plant will not cause electrolyte imbalance and liquid concentration rise]

With this explanation of the system, Chen Cheng almost understood the role of this special, undiscovered plant auxin.

This is why wild tangerines taste so bad, because their body stuffs excess minerals into the fruit as garbage.

A plant growth hormone that has never been discovered!

This should be a discovery that can shock the world's biological world, right?!

Chen Cheng froze for a moment, trying to calm his restless mind.

He had to solve the current problem of Yanyuan orange first, sort out the findings, sort out the papers and publish them.

"So from the current point of view, is this mineral operator good or bad for the orange trees planted in Yanyuan County?"

Chen Cheng pondered for a moment, and then retrieved the information of the salt source mandarin stored by the supercomputer before.

"There is no mineral operator in the auxin of the salt source orange?"

[Yes, the system judged that this may be the reason why Yanyuan mandarins have suddenly entered aging in the past two years, resulting in a decrease in quality]

"Because Yanyuan mandarin is a new variety cultivated by artificial improvement, it is not suitable for the local soil characteristics of Yanyuan, and over the years, it has led to excessive accumulation of minerals in the body, causing early aging?"

【Yes】

In this case, it is really possible that the quality of the soil in the salt source is causing the problem of salt source oranges.

No wonder Zhu Yimin invited so many experts, but they did not find the essence of the problem, let alone solve the problem.

Now that the problem has been found, the solution will naturally come to light.

That is to sprinkle the saline mandarin with the mineral auxin.

"Analyze the effect of wild mandarin auxin on salt source mandarins!"

[Need to consume one experiment, do you want to start?] 】

"Let's go!"

Chen Cheng didn't even think about it, he now has more than 1 million reputation points in his hand, and he only needs to consume a mere 1,000 reputation points to do an experiment. That's a drop in the bucket, okay.

With plenty of prestige, it's so arrogant.

With 1,000 reputation points deducted, the supercomputer here is running.

It completely virtualizes the entire plant of the salt source tangerine and adjusts the parameters to the current growth conditions.

The auxin extracted from wild mandarins is then formulated and divided into three equal parts.

The first method of infusion is to introduce auxin into the tangerine, that is, it is common to hang an infusion bag on the tree, make a hole in the tree, and insert the syringe needle into the hole to achieve liquid input.

Depending on the type of infusion, the depth of the opening is also different, because there are two types of catheters for plant bodies, catheters and sieves.

The ducts are located in the xylem of the stem of the plant body, and transport the water and inorganic salts absorbed by the roots upwards to all parts of the plant's body. The sieve tube is a pipe that transports organic nutrients in the phloem (inner bark) of the plant, which is composed of many tubular living cells connected up and down to transport organic matter from top to bottom.

The difference is that the duct transports the water drawn from the rhizome upwards, while the sieve transports the nutrients formed by the upper leaves downward.

The second method of application simulated by the supercomputer is direct whole-plant spraying. The whole is more reckless and more labor-saving, and it is directly sprayed with a sprayer on the entire canopy.

The third application method is to apply auxin to the skin of the tangerine.

Although this method is time-consuming and labor-intensive, it is indeed one of the most effective ways to improve the effect of the finished fruit.

Chen Cheng remembers that in one place, calcium hydroxide, commonly known as lime water, was applied to the oranges to make the skin thinner and increase the water content.

The supercomputer quickly simulated the results of the three application methods.

[Infusion method: 60% plant absorption rate, can effectively improve the current senescence problem of plants, but only effective within the effective period, the onset time is 10-30 days, and the dosage of one plant is 0.5 liters]

[Whole plant spraying method: plant absorption rate of 45%, general effect, onset time of 10-30 days, dosage of 1 liter per plant]

[Application method: plant absorption rate 20%, fruit absorption rate 70%, onset time 2-3 days, dosage of one plant 0.3 liters]

The results were clear at a glance, and Chen Cheng naturally chose the smearing method, because Zhu Yimin said that this batch of fruits would be more than 10 days before the centralized picking period, and the time was very tight.

In addition, the application method also saves the amount of auxin nutrient solution.

"System, tell me the effect of the salt source mandarin on the ripe fruit after the wild mandarin is applied."

[After sprinkling, it will promote the salt source tangerine to accelerate the accumulation of sugar, increase the sweetness, and at the same time, the mineral transporter will also transfer the minerals absorbed by the plant to the fruit]

"Isn't that the salt source tangerine also become bitter and astringent?" Chen Cheng frowned and asked.

[No, the first is that the amount of minerals in the short term is not large, and the second is that the fruit of the salt source mandarin is more than twice as large as that of the wild mandarin]

"Can't you just remove the mineral operanin from the growth promoter?"

[It is not recommended to reject, the mineral operanel will bring a lot of water into the fruit when it is running, so as to increase the water content of the fruit. These trace elements are a burden to plants, but they are necessary for the human body]

Chen Cheng nodded.

Biology is a wonderful thing, and what you see is often the result of a combination of many factors.
