The farmer turned around and left, and Chen Cheng hurriedly followed.

Seeing that Chen Cheng was leaving, Zhang Dawei had to follow, and then County Magistrate Zhu took a wave of cooperative farmers to follow.

"That's a variety that we have always had in our local area, and there used to be a lot of them, but after planting new varieties of oranges, they were all cut down, and there were still two trees left in our village."

The peasant walked as he walked. He felt that Chen Cheng's tone just now was very anxious, so he didn't take the cement road, but chose the rugged and muddy path.

This way down, one time climbing, one time downhill, another time downhill, the roadside is weeds and boulders.

Under the scorching sun and the sweltering steam of the ground moisture, Chen Cheng was drenched in a short time.

The same is true for Zhang Dawei and Zhu Yimin.

However, what was more difficult for the two of them than Chen Cheng was that before they reached the entrance of the village, their faces were already red and their legs trembled.

This is the difference in age and physical strength.

Twenty minutes later, the group finally arrived at the entrance of the village.

The peasants often walk the mountain road, and such a part of the road is simply not a problem for them, that is, the weather is a little hot today.

More than a dozen people looked at Chen Cheng, who was standing on the side wiping his sweat, and then looked at Zhang Dawei and Zhu Yimin, who were supporting their legs with their hands and bending over next to him, and couldn't help but secretly admire.

"Not to mention the quality of the technology, the attitude of this little expert is really not to say, the experts who came in the past are standing on the side of the cement road and walking at a glance, this young man can endure hardship."

"It's just too young, just at this age, I'm afraid the technical level is not very good."

As members of the cooperative of the orange planting base, they have almost been disappointed in this matter. Coupled with the preconceived notion of "experts", they still do not trust Chen Cheng.

The two wild orange trees were in the grass on the side of the road at the entrance of the village, and they looked much taller than the orange trees they had planted in a large area, with narrow and lush leaves, and small and few hanging fruits.

This is the result of two orange trees competing with the weedy trees next to them without pruning and irrigation.

They can only grow taller and more lush in order to absorb more nutrients and survive.

Chen Cheng ignored the pulling and cutting of the weeds next to him on his arms, and directly waded through the weeds and walked to the two orange trees.

This time, Zhang Dawei and Zhu Yimin did not follow.

Chen Cheng observed the two trees for a while, jumped up and picked two small oranges, and then returned to the road.

He peeled one open, snapped a small petal, and put it in his mouth to chew.

“tui！ tui！ ”

This wild tangerine is bitter and astringent, and there is even a hint of saltiness in it.

This is the most unpalatable orange Chen Cheng has ever tasted, and there is no one.

"Why does this orange still have a salty taste?" Chen Cheng frowned and asked.

The farmer who led the way hurriedly said: "Expert Xiao Chen, you don't know, why our Yanyuan County is called 'Yanyuan' is because the land has a high salinity content, and we used to be a famous salt-producing land here!" ”

Zhu Yimin, who finally got his way, came over and added: "So in our county, we can only grow cash crops, not grain harvests." ”

"So your county doesn't grow autumn soybeans either?" Chen Cheng asked.

"Less, less."

Chen Cheng finally understood why the peasants here didn't know anything about his name. Dare to love that last time, they didn't have the experience of using his technology to save autumn soybeans.

"It doesn't matter, this time will definitely let you know me deeply." Chen Cheng thought.

The high salinity of the land has led to the absorption of salinity by the orange trees that have been wild for many years and store it in the orange fruits?

With doubts, Chen Cheng put the orange in his hand into his sight.

[Wild orange varieties were detected, with a sweetness of 0.2, a moisture content of 80%, a sodium chloride content of 5%, and a mineral trace element such as zinc, calcium, selenium, iron, and riboflavin]

"Contains so many trace elements?"

He had already tasted the saltiness just now, so it was not surprising that the system identified that it contained sodium chloride, and the miraculous thing was that this wild orange contained so many trace elements.

It seems that in order to survive and compete, wild orange trees have absorbed all the trace elements in the soil into their bodies and accumulated them in the fruits.

That's probably why it tastes so bitter.

"How many years will this wild orange tree survive?" Chen Cheng turned his head and asked.

The farmer who led the way said, "At least twenty years, they were there more than ten years ago." ”

"That means these two wild orange trees are still very young, so it's no wonder that the fruit has a high moisture content." Chen Cheng said.

He silently called up the system.

"These two wild orange trees are in the prime of life, and they belong to the same orange family, so they should be able to meet the conditions for extracting auxin nutrient solution."

[Calculating...]

[The results of the calculation show that the auxin in these two wild orange trees can be used to make a nutrient solution, please collect a somatotropin sample and conduct an experiment]

Exiting the system, Chen Cheng looked at the wild orange tree in front of him.

In agricultural technology, whether it is hybridization or grafting, wild varieties can sometimes give unexpected surprises.

Because of the apical dominance, the auxin of plants is generally found in large quantities in the apical shoots. You need to pick some top branches to go back before you can enter the super agricultural technology laboratory for extraction experiments.

The branches of the wild orange trees were thin and long, and there were thorns on the trunks, which Chen Cheng could not pick at all.

"I need to pluck some twigs on top of them, can you help me figure it out?" He asked the farmer next to him.

"It's not easy, I'll just go get an axe and chop it off."

Chen Cheng raised his hand and said, "No, these two trees may still have research value in the future." You can help find a ladder to pluck a few shoots. ”

"Okay." The peasant ran back to the village and in a short time brought a ladder.

He is also too realistic, Chen Cheng clearly said that he only needs two or three, he directly picked a large handful, and tied it with a straw rope, and arranged it obediently.

Fortunately, these top shoots will sprout new ones next year.

Taking a handful of buds, Chen Cheng arranged for Zhu Yimin to prepare for spraying nutrient solution on all the orange trees tomorrow, and then took the car back to school.

Back in the laboratory, Ding Tao and the others were already working on tidying up the laboratory, because Zhao Feng had approved another laboratory for them, which was next door to their laboratory.

Chen Cheng moved his instruments and equipment to the outside, leaving only the biological replicator inside.

Ding Tao's place where they did the experiment was changed to the next door, which is equivalent to the previous laboratory can be used by him alone.

There's a lot of space in the room, just enough space to extract the upgraded creature replica into reality.

Chen Cheng entered the system, selected the upgrade biological replica machine, and clicked Extract Now.

Then he watched as the Bio Replica V1.0 placed on the ground suddenly grew larger, becoming a washing machine-sized Bio Replica V2.0.

This thing is so sci-fi that most people would faint on the spot.

Fortunately, Chen Cheng is no longer surprised.
