"It's... This..."

Zhu Yimin was a little speechless by the news.

When Chen Cheng said that the sweetness and water content had increased just now, he was even happier than hearing that his daughter-in-law's second child was a daughter, but what kind of sweet and salty tangerine is this?

He was stunned, stunned.

Chen Cheng looked at Zhu Yimin's round face, and explained: "County Magistrate Zhu, this auxin-promoting nutrient solution is extracted from wild mandarins, so it will contain some characteristics of wild mandarins. ”

He thought for a moment and added: "Our batch of tangerines is rich in trace elements such as zinc, calcium, selenium, iron, etc., which is much higher in nutritional value than other tangerines on the market!" ”

Zhu Yimin still hasn't turned a corner, he feels that the original tangerine tastes the best and is the most recognized by the market.

Now get a batch of sweet and salty oranges out, will anyone buy them?

Zhang Dawei, who had been listening to the side, was the first to react.

He patted Zhu Yimin on the shoulder and said, "County Magistrate Zhu, I think you are going to make a fortune this year!" ”

Zhu Yimin was even more confused, and looked at Zhang Dawei with a puzzled expression.

Zhang Dawei said: "It seems that County Magistrate Zhu has never drunk a functional drink, and a bottle of functional drink with added electrolytes and trace elements is several times more expensive than a bottle of orange juice!" Besides, you're all natural! ”

Zhu Yimin patted the back of his head and said in surprise: "Section Chief Zhang means that this sweet and salty tangerine will be very popular in the city?" ”

Zhang Dawei said: "Don't worry, with this gimmick, I will arrange for your products to be promoted on TV stations and the Internet to ensure that you make a lot of money this year!" ”

Zhu Yimin smiled apologetically at Chen Cheng, his round face looked a little cute without the majesty of the county magistrate.

Back on the road, Chen Cheng found more than a dozen farmers from the cooperatives and explained to them in detail the proportion of nutrient solution preparation and the key points of application.

They are all people who have been engaged in the cultivation and management of oranges for many years, so naturally they quickly grasped the main points.

"Go ahead, remember, don't spread too much on each orange, try to be as evenly as possible."

With Chen Cheng's order, more than a dozen people drove to various villages in Yanyuan County with the growth promoter essence divided according to the number of acres.

The nutrient solution was also prepared, and the villagers lined up, carefully packed into small barrels, and then dispersed into the orange groves on the hillside.

Seeing that everyone was busy, Chen Cheng also took a small bucket and joined the ranks of applying nutrient solution to the oranges.

Zhang Dawei and Zhu Yimin also followed with buckets.

The sun showed the power of the 'Autumn Tiger' to the fullest, and after a while, Chen Cheng was already sweating all over the orange grove.

He can still withstand this bit of heat, the only discomfort is the stinging pain of his arm that was cut by weeds when picking wild oranges yesterday under the sweat soaking.

It was sour, like a row of ants biting.

"Section Chief Zhang, how did your province discover a talent like Expert Xiao Chen?" Zhu Yimin leaned over to Zhang Dawei and asked in a low voice.

Zhang Dawei said with a smile: "In order to invite him, the province directly rewarded him with an experimental building, and our Director Wang has taken great pains to solve your orange problem!" ”

Zhu Yimin nodded again and again: "Thank you, Director Wang, for being so concerned about the agricultural development of our county." ”

"So, don't let down Director Wang's hard work." Zhang Dawei exhorted with the frame of a provincial-level official

Zhu Yimin was like pounding garlic again, and then asked: "But Expert Xiao Chen's method can only manage this batch of fruits, what should I do next year?" ”

Zhang Dawei didn't speak, and pouted at Chen Cheng.

Zhu Yimin immediately understood, and ran towards Chen Cheng, who was looking up to wipe his sweat.

"Expert Xiao Chen."

Zhu Yimin handed over a clean towel.

"County Magistrate Zhu, what's the matter?"

Zhu Yimin said with a smile: "Our batch of orange trees, if we don't replant them, will they still be saved?" ”

Chen Cheng said: "If you don't say it, I will consider it, after all, if there is no income for more than three years, the farmers will lose a lot of money." ”

"Yes, yes, yes." Zhu Yimin nodded violently.

Waiting for Zhu Yimin to leave, Chen Cheng silently called up the system.

"Searching for a solution that will revolutionize the aging of salt-based orange trees."

【Okay】

...

[Grafting technology can be used to change the problem of early aging of salt-source tangerine trees due to soil problems]

"Is it scion grafting with wild mandarins?" Chen Cheng frowned and asked.

Because since the problem is solved by using the auxin extracted from wild mandarins, grafting is also likely to be feasible.

【Yes】

"But doesn't grafting change the properties of the original body? Wouldn't that be bitter and astringent after grafting? ”

[Conventional grafting methods cannot be used, top grafting methods must be used]

"Apical grafting?" Chen Cheng said he had never heard of it.

[There is no need to prune off the existing mature branches of the salt-source mandarin, just graft the branches and buds of the wild mandarin on the top part of the branch buds of the salt-source mandarin tree, and guide it to produce the same somatotropin as the wild mandarin]

Listening to the system's explanation, Chen Cheng understood the technical principle.

That is, the top grafting is used to induce the saline tangerine tree to produce the same auxin as the wild mandarin, but the mature branches it uses to bear fruit still have the original characteristics.

The principle is to take advantage of the apex of the plant.

It's a brilliant technical idea to get the best of both worlds.

Chen Cheng immediately withdrew from the system, summoned Zhu Yimin, and asked him to arrange for someone to pick a few more branches and buds of wild orange trees, and he began to look for orange trees suitable for grafting.

Just do it is his style of doing things.

The special knife and tape for grafting are the standing tools of the orange planting cooperative, and when everything is ready, Chen Cheng directly found two smaller orange trees to start grafting.

Looking at his unique top grafting method, the farmers who finished their farm work gathered to watch.

One by one, I just thought it was very novel and unreasonable, but no one dared to question it. Because the group of people who questioned yesterday are all working with red faces today.

Chen Cheng separated the phloem at the top branches of the two tangerine trees, then cut the branches and buds of the wild tangerines at matching angles, inserted them, and then tied them with tape, which was considered the completion of the grafting.

Zhu Yimin was amazed and blew a rainbow fart at Zhang Dawei: "Section Chief Zhang, don't say anything else, Expert Xiao Chen's innovative thinking is really inferior to me, the county magistrate." ”

Zhang Dawei said lightly: "Well, the last one like you said was Academician Zhou Kai. ”

"Academician Zhou... Also..."Zhu Yimin choked back the words that followed.

He suddenly felt that he was a county magistrate, and he was no longer qualified to blow Chen Cheng's rainbow fart.

Chen Cheng returned to the road and arranged follow-up work with Zhu Yimin, and Zhu Yimin directly took out a small notebook and began to record carefully.

"Three days later, I picked a few oranges and sent them to my lab for testing. I will come back in 5-8 days to see if the graft is alive, although it is not the golden time for grafting, there should be a few successful grafts. ”

Zhu Yimin said as he wrote: "Expert Xiao Chen, you are too modest. ”
