"Don't have a meeting, go straight to the mountain?"

The members of the cooperative, who were about to disperse, suddenly became interested.

"This expert is a bit interesting, according to the process, the experts must not hold a meeting first, look at a few pictures to analyze the conclusion, and then go around the mountain to finish the matter?"

"I'm afraid he doesn't even have the ability to read pictures and speak, right?"

"Why don't we go and have a look?"

"That's it, follow and see how he's fooled!"

Zhu Yimin, the county magistrate, cast an inquiring look at Zhang Dawei, and Zhang Dawei nodded.

So the group got into the car and drove to the citrus plantation outside the county.

When he arrived at the place, as soon as he got out of the car, Chen Cheng felt a burst of damp heat rushing to his face.

It's the middle of October, but the sun is shining on the mud that has just rained, and the smell of earth is shining.

This citrus grove stretches over half a mountain, about 30 acres. There are also some farmers weeding among the orange groves.

Zhu Yimin stood beside Chen Cheng, pointed to an orange tree in front of him and said, "This is our first batch of orange trees planted in a large area. In the first ten years, the product quality was good, and the benefits were very good.

However, in the past two years, these orange trees have entered the aging period, and the sweetness and water content of the tangerines have decreased, resulting in the sales of the products being hindered. ”

"What is the scale of this batch of tangerine trees?" Chen Cheng asked.

Zhu Yimin sighed and said, "Almost five hundred acres, it's all like this." ”

"Five hundred acres?!" Chen Cheng was a little surprised.

A trace of embarrassment flashed on Zhu Yimin's face, and he nodded: "Yes, we spent a lot of effort to call on the whole county to plant the first batch of orange trees on a large scale. ”

Chen Cheng has learned relevant knowledge in the system before, according to the law of perennial cash crop planting, it is necessary to plan the planting cycle interval of each batch to ensure that the number of plants in each growth cycle is reasonably allocated, so as to effectively avoid risks.

Obviously, Zhu Yimin and the others should have been hot-headed at that time, and in order to produce results, they planted the same batch of orange trees in a large area at one time.

This is called haste is not reached. Obviously, Zhu Yimin's policy was wrong back then.

Chen Cheng didn't say anything, just nodded slightly.

Zhu Yimin said: "The peasants have been losing money for two consecutive years, and if this continues, it is estimated that the peasants who have finally returned to their hometowns will have to go out to work again." ”

Only by developing the economy of the region and allowing farmers to make money can we retain the population, and only by retaining the population can we stimulate consumption and promote economic growth, which is a cycle.

If one of these links is broken, then the entire economy of Yanyuan County will fall into another vicious circle.

It's too hard to turn it back.

The farmers who grow tangerines are anxious, and Zhu Yimin, the county magistrate, is even more anxious.

But anxiety is anxiety, and this matter is difficult to solve.

Zhu Yimin also didn't believe that Chen Cheng, who was in his early twenties, could help them rejuvenate. It's just that in front of the section chief from the province, he has to accompany this "expert" to complete the process.

Chen Cheng frowned and said: "The tree is aging, according to the situation, the entire trunk should be directly sawed off, and then a new scion should be grafted on the rootstock." ”

In agricultural grafting terminology, rootstock refers to the base of grafting, and scion refers to the bud bud tissue to be grafted on the base.

Hearing Chen Cheng say these professional terms, Zhu Yimin was slightly surprised.

It seems that this young man still knows at least a little bit of professional technology.

He said: "Yes, but the tree is too old to graft buds on the branches, and the whole tree must be sawn off and grafted from the trunk roots to ensure that the grown orange tree has a new life cycle." ”

Chen Cheng understands this truth. In general, grafting buds on branches is only used to improve the variety and does not continue the life cycle of the plant.

Zhu Yimin continued: "Grafting from the roots of the trunk takes at least three years to bear fruit, and the time is not much shorter than replanting. We can't afford to wait! Three years is enough to exhaust all the efforts we made in the previous ten years. ”

Chen Cheng nodded and stopped talking.

There was an orange tree beneath the concrete road where they were standing, and he was going down to see how they were growing.

He walked a little further and saw a path without weeds, so he stepped on it. But before his second foot landed, his feet began to slip, and the whole person slipped forward with him, and then fell down with a thud.

It had just rained, the mud on the ground was slippery, and his sneakers were not slippery at all.

"Brother Chen Cheng!"

Zhang Dawei exclaimed, hurriedly ran over, wanted to help him up, and then like Chen Cheng, he fell with a big butt.

"Section Chief Zhang!"

Zhu Yimin shouted, hurriedly ran over, wanted to help Zhang Dawei up, and then also fell.

Both of their leather shoes are less slippery.

The members of the cooperative standing on the side of the concrete road were trying not to hold back their laughter, but a few of them couldn't hold back their laughter.

"The experts have never been to the ground, and neither have the section chiefs and county magistrates." Someone teased.

"Let's go! Let's go down and have a look. ”

The group walked down the path with confidence, and suddenly one person did not step on it steadily, and pulled down a large area. Everyone got up silently, and no one laughed out loud anymore.

Chen Cheng patted the mud on his buttocks, didn't care about his image, and walked to an orange tree.

According to the climatic conditions of Hansi Province, the ripening time of mandarins is between October and December. These oranges have reached the green fruit stage, and each tangerine tree is full of fist-sized turquoise orange fruits.

Zhu Yimin took one off, broke it in half, and handed it to Chen Cheng.

"You see, the cortex of the tangerine thickens, the flesh inside shrinks, and the water content decreases."

Chen Cheng broke a petal and put it in his mouth, and a pungent sourness exploded in his mouth.

"How long will it take for this batch of oranges to ripen?" He asked.

Zhu Yimin said: "You can pick it in ten days." In order to ensure long-distance transportation, tangerines are generally picked in large quantities when the green fruits have just turned yellow. ”

Chen Cheng leaned the orange in his hand into front of him, and a system sound sounded in his head.

【Green fruit stage tangerine variety, sweetness 1.0, moisture content 70%】

[It was detected that the sweetness of the variety was reduced to 0.6 and the moisture content was 55% due to the late growth of the plant, do you search for a solution?] 】

Sweetness is also known as specific sweetness. Sweetness is a relative value, usually sucrose as the benchmark, generally 5% or 10% sucrose aqueous solution at 20 °C sweetness of 1.0, other sugars are compared with it.

"Search." Chen Cheng said secretly.

【Okay, start searching】

In less than a minute, the supercomputer gave the solution.

[Solution: Spray the same plant growth promotion nutrient solution]

"What do you mean by a plant of the same kind?"

[Tangerine plants with similar habits to the current tangerine plants and are in the vigorous growth period]

After figuring out the principle of the solution, Chen Cheng immediately quit the system.

"County Magistrate Zhu, do you still plant oranges similar to this batch of mandarins here?" Chen Cheng asked.

Zhu Yimin shook his head and said: "In order to build a characteristic industry in citrus county, we planted late-maturing ugly oranges in the later batches, which are still in the flowering period and will not mature until the beginning of next year." ”

"There are no ripe orange varieties now?"

Zhu Yimin shook his head, then reacted and beckoned a cooperative farmer next to him to come over.

"Do we have any oranges in our village that are now hanging green fruits?" He asked.

The farmer scratched his head and said, "There is a kind of local wild orange, but it is bitter and salty. ”

Chen Cheng's eyes lit up: "Where is it?" Take me to see it! ”
