After changing the water in the paddy field, and after everyone left, Qian Duoduo took a few drops of river water from his farm space. His farm fields were all irrigated with this river water, so a few drops shouldn't matter, right?
After finishing, Qian Duoduo immediately looked around. Hmm, there wasn't anyone there. She clapped her hands and then wandered around her own spot.
There are several big trees near this experimental field. Qian Duoduo looked at the place and thought it was a good spot. It really is a place where you can have the shade of big trees behind you (he inexplicably hummed a line from the movie "The Battle of Wits" and wrote it down (#^.^#)).
Seeing that no one was around, Qian Duoduo slipped behind a big tree and entered the farm. He found Su Ruanruan, bought a fisherman's stool from her, tried it out, and found it quite comfortable. He paid the gold coins readily and came out of the farm again, but this time he was carrying the fisherman's stool in his hand. He walked to a shady spot, set it up, and picked up a book that he always carried with him to read.
Professor Yuan, holding the water quality test results, returned to Qian Duoduo's paddy field. There, he saw Qian Duoduo reading a book. He couldn't help but nod in approval. This student was truly studious, and it was this very spirit that made her the top student in the entire grade.
Qian Duoduo was startled when she heard footsteps, after all, her stool was not a product of this era!
When Professor Yuan saw Qian Duoduo stand up, he smiled and said, "Qian, you're doing very well. We just checked the water in your paddy field and found that it contained fertilizer with high potassium content. I suspect it's potassium dihydrogen phosphate, but this fertilizer is supposed to promote plant yield. How could this be?"
Qian Duoduo said, "I know this. It's generally best to dilute potassium dihydrogen phosphate by 600-800 times. The application rate is about 200g per acre, and the application time is generally in the later stage of crop growth. Phosphorus fertilizer and potassium fertilizer play an important role in the vegetative growth of crops and can improve crop quality."
Professor Yuan nodded at Qian Duoduo's words and said, "You remember these things very well."
Qian Duoduo added, "But this is not absolute. If the other party uses potassium dihydrogen phosphate at a concentration lower than 20 times when irrigating the roots, it will cause seedling burn and fertilizer damage to the crops."
Professor Yuan nodded upon hearing Qian Duoduo's words and said, "You're right. With such knowledge about fertilizer use, it seems the other party doesn't want to give you any benefits at all!"
Qian Duoduo sighed and said, "Alas! The tallest tree in the forest will be felled by the wind; the highest mound on the bank will be eroded by the current; the most outstanding person will be criticized by the masses. The lessons of the past are not far off, and we will follow in their footsteps."
Professor Yuan couldn't help but laugh when he heard this. This little girl was truly both lovable and infuriating. He loved that she was a hardworking and ambitious student, just like she was reading a book a moment ago. But her smugness was so infuriating that he just wanted to kick her a couple of times!
Qian Duoduo said, "Professor, I've never used chemical fertilizers on this land. I just want to see the difference between this purely green and pollution-free product and the product that has been treated with chemical fertilizers. But it's obvious that they don't want me to achieve this goal!"
Professor Yuan said, "Why do you think that way? Generally speaking, the yield of things you grow like this will be relatively low, which does not conform to the farmers' expectations, nor does it conform to the current national conditions."
Qian Duoduo nodded and said, "Professor, I know all of this, but what I'm thinking is that our country has such a large land area, and it would be boring if everyone planted the same things. If there were such pollution-free products, wouldn't it be healthier for our bodies?"
Professor Yuan smiled: "Yes, you can keep working hard. Our country has developed from having no food to eat, to not having enough to eat, to now having enough to eat, and it will develop even better in the future. This requires students like you to create it!"
Qian Duoduo laughed and said, "Professor, I think you shouldn't be a university professor; you should be a restaurant owner."
Professor Yuan asked, "Why?"
Qian Duoduo said, "The pancakes you make must be delicious!" After saying that, she bowed to Professor Yuan, then picked up her fisherman's stool and ran off.
Professor Yuan watched the figure run away, still puzzled. How did she know that she could make pancakes?
After class every day, Qian Duoduo would still wander around his paddy field. Sometimes, Jiang Sisi and Lu Fen would follow him. When Jiang Sisi saw Qian Duoduo's fisherman's stool, she really liked it and kept asking him where he bought it, which led Qian Duoduo to promise to buy one for each of the other people in the dormitory.
Because Guo Ni was still on a paid trip and hadn't returned, the other three were overjoyed to see the same style of fisherman's stools but different colors. One summer afternoon, the four of them took the fisherman's stools to the big trees, set them up, placed the cardboard box containing the stools in the middle, took a deck of cards, and started playing '50K'.
This was Qian Duoduo and Tian Rong's forte; the two of them, each leading Jiang Sisi and Lu Fen, got into a fight.
Qian Duoduo looked at Jiang Sisi across from her and said, "My future third sister-in-law, can you handle this? The speed at which you're playing cards is almost as fast as the speed at which you and my third brother are dating!"
Jiang Sisi blushed, threw away the three pairs in her hand, and said, "Xiao Duoduo, don't talk nonsense. Your third brother went on a business trip with Director Lu. Otherwise, do you think I would be here playing cards with you? I would have gone to find my girlfriend long ago!"
Qian Duoduo: "Oh, it's obvious that my sister's status in the family is declining. You know that my third brother went on a business trip, but I didn't know. No way, when my third brother comes back, I will definitely ask him for a gift, otherwise I won't be able to make up for my wounded little heart!"
