In the scorching summer, the sun overhead is like a furnace in front of his face, struggling to bake Zhong Di's face.

The cotton fields were endless, and the breeze blew gently, blowing the cotton leaves, making a rustling sound, which also brought Zhong Di a short period of coolness.

As a county-level city that has just risen, Chongyang City's entire economic development still depends on agriculture to support, and the rest of the economic system is still immature, and most of them are still in the exploration stage.

In the entire northwest region, Chongyang City, as the main cotton producing area, accounts for almost one-third of the cotton production in the entire northwest, all of which is naturally due to the current agricultural planting model.

In addition to the need for manual labor in individual processes throughout the year, almost the whole process is mechanized and standardized, saving a lot of labor and reducing countless costs, which is one of the important reasons why Chongyang City can be promoted to a county-level city.

The temperature at noon was extremely high, making Zhong Di, a recent graduate, unbearable, and his head began to buzz.

The loud noise of the tractor filled Zhong Di's ears, making his already uncomfortable head even more dizzy.

"Zhong Di, what's the daze, keep up with the machine. ”

Not far away, a middle-aged man with slightly graying hair roared.

This is Wang Lu, the master who took him, who has been engaged in field operations for more than 20 years and has sufficient experience in front-line production, which is why Zhong Di chose him as his master.

Zhong Di was stunned, his head was still buzzing, and his eyes looked at the somewhat vague spraying tractor in front of him, feeling that he was about to leave this world.

Zhong Di froze and shouted loudly: "Yes, master." ”

This is his own choice, after graduation, he directly entered the production line, hoping that he can become a top agricultural expert, not to mention that he can be as good as the idol Old Man Yuan, but also to make small achievements and contribute to the great China.

As a result, how long has it been since it was too hot to support the scorching weather?

The week before was fine, the sun was not so big, and it could withstand it, but today, it was really a little unbearable.

Zhong Di, who was about to give up, suddenly thought of Old Man Yuan, we are people with idols, we can't embarrass idols, Zhong Di thought of this, patted his head vigorously, and then gathered his attention.

"Pay attention to every little bit of difference you see, maybe this little bit of difference can have a big impact on the cotton yield that year. ”

Master Wang Lu looked at Zhong Di and explained the main points to Zhong Di.

He liked this young man very much, so he told him some of his experience.

Nowadays, there are very few young people who are willing to step into the production line, the reason is very simple, they can't bear this hardship at all, most young people are in high spirits, but they can't even hold on for a day, when Zhong Di chose him, he only because of the company's arrangement, he did not refuse.

Originally, he planned to teach nothing and leave him to fend for himself, thinking that he would get out of the way for three days at most, but in the end, he persevered, and it was only yesterday that he began to slowly teach this young man something.

Seeing Zhong Di following the machine and observing carefully, Wang Lu nodded with satisfaction.

"Do you know why you have to follow the machine? Actually, this part was supposed to be hit by a drone, but then you won't have the opportunity to follow on the spot and learn from the experience. ”

Wang Lu spoke in a calm tone and said the reason for using a tractor to spray medicine today.

Nowadays, in addition to training some newly recruited agricultural technicians, the rest of the pesticides are used as much as possible when drones can be used.

Nowadays, drone technology is not particularly mature, but it is enough to cope with current production and can play a good role in saving costs.

"Thank you, master. ”

Zhong Di knew this, so he also understood that the master was so that he could learn something and say something of thanks, which was a routine operation.

He said very little, not that he didn't want to speak, but now he just felt like his head was about to explode, and he really didn't want to say more.

"Do you remember today's medication?"

Wang Lu quickly asked a professional question, and after asking, he looked at Zhong Di with some expectant eyes.

"2,000 times of avermectin, 3,000 times of pyridafen, and 1,000 times of diammonium phosphate are sprayed on the foliar surface. Zhong Di said while reminiscing.

Wang Lu nodded: "Tell me your understanding." ”

Zhong Di looked at the cotton that had not been sprayed not far away, the leaves were slightly drooping, and the young leaves were a little yellow, not the kind of rich green, judging in his heart.

"Recently, the temperature is high, the foliar surface shows a state of water shortage, and at the same time there are symptoms of nitrogen deficiency, the mixed application of avermectin and pyridafen is mainly to control spider mites, and the use of diammonium phosphate is to supplement the nitrogen fertilizer lacking in the plant. ”

As soon as Zhong Di finished speaking, he felt that his head was dizzy, and he suddenly lost consciousness, and in just a moment, his consciousness returned again, returning to his original state, or even better.

"Well, the explanation is basically correct, but it's too general, if it's general production, these are enough, but for the company's current production scale, your level, it's better to shut up. ”

Wang Lu was very satisfied in his heart, but he definitely couldn't show it on the surface, if he wanted to destroy a person, then the best way was naturally to praise him, but Wang Lu didn't want to do it.

Zhong Di, who came back to his senses, looked at the cotton in front of him in a little dazed, rubbed his eyes in disbelief, and then looked at it, and the cotton at this time, in his eyes, seemed to have become a little different.

He could clearly see the many strange characteristics of cotton, which seemed to be talking to him and conveying something.

The biggest reason for this cotton seems to be the lack of water!

This ridiculous feeling filled Zhong Di's brain, why could he feel that Cotton was talking to him?

This is an illusion, Zhong Di rubbed his eyes again, and when he opened it, he looked at the cotton with a little expectation and a little nervousness, the strange feeling disappeared, Zhong Di breathed a sigh of relief, fortunately he couldn't feel it, otherwise he thought there was some hallucination.

"Zhong Di... Zhong Di..."

At this time, the master's voice suddenly appeared in Zhong Di's ears.

"Ahh Master. ”

After Zhong Di reacted, he hurriedly responded, and at the same time, his head was still thinking about the strange feeling that had just happened.

Wang Lu frowned, his face was a little displeased: "What are you doing here? I just asked you a question, do you have any eyebrows?" ”

Zhong Di shook his head, and said in his heart: I didn't hear anything just now, what kind of eyebrows can I have, I can only pretend not to know like now, otherwise the master will definitely be angry!

"You have to remember that we do field plant protection, we must have a keen sense of observation, always pay attention to some subtle differences, experienced agricultural technicians, as long as you stop here, you can see the existing problems in the cotton field, as well as the potential problems in the cotton field. ”

As soon as Wang Lu talked about his profession, his whole temperament became unusual.

"Master, I have a little problem, avermectin plus pyridine miteline to control red spiders, I can still understand, but this nitrogen deficiency, I think urea can also solve this problem very well, and the nitrogen content of urea is higher than that of diammonium phosphate. ”

Zhong Di definitely won't say nothing, doesn't it seem that the master's teaching has no effect?

As soon as he heard Zhong Di ask this question, Wang Lu really grinned, it was in vain that he had just spent so much talk, and Wang Lu, who was happier for a while, just brewed it in his mind for a while, and then knew what to say to Zhong Di.

"Okay, I'll explain to you, when we agricultural technicians encounter problems, what we think about is not only to solve the current problems, but also to consider the future problems. ”

"What month is it now? July, what you are thinking about, not only the problem of nitrogen deficiency, but also the problem of flowering, although urea can be a good supplement of nitrogen, but at the same time, its main role is to raise seedlings, if this will also use urea, then how to control the flowering period after that, how to control the growth potential of the plant? So, this is also the reason for the use of diammonium phosphate. ”

"Diammonium phosphate is not only a gentle nitrogen supplement, it also has a role in providing phosphate fertilizer, which is also a means to promote flowering, and a foliar spray solves more than just the current problem. ”

Wang Lu quickly explained his understanding of this fertilization, Zhong Di listened and nodded, and wrote down the master's deep insights on this spraying of foliar fertilizer.

If it is an ordinary person looking at this problem, it may be particularly one-sided, nothing to pay attention to, and even the concentration is casual, probably just come and be done, but the master is different, and he is worthy of being an agricultural technician with 20 years of front-line production experience.

As Wang Lu and Zhong Di talked, the tractor drove farther and farther, and the voices between them became clearer and clearer.

Zhong Di looked at the cotton, his eyes became a little erratic, was that feeling just now, was it an illusion?

"Master, this time the use of avermectin and pyridamide is about the prevention and control of red spiders, which is no problem, but how do I feel, this time the state embodied by the cotton plant is a lack of water, let's just hit avermectin with pyridamine, this can also be done, but this will lead to a large increase in cost, and more importantly, there is no basis for judgment, just use it directly, it always feels a little weird." ”

The information that cotton revealed to herself just now is that there is a lack of water, and I asked this because I wanted to find out, otherwise I wouldn't have to sleep tonight, just thinking about such a thing is enough to disturb me.

"Oh, you're questioning my judgment?"

At this time, a slightly vicissitudes of life voice appeared behind Zhong Di, and he saw a little more nervousness in the eyes of his master Wang Lu, and then frantically gave Zhong Di a hint.
