"Paper, pen, it's too dark, open the curtains."

Lin Yuzhu shook her numb arms and pushed away the dipped pen he handed over in disgust.

The two plastic flower-pole dip pens on the table can be considered old employees of the production team.

There is no long water reservoir like an ordinary fountain pen. There is only a small water reservoir on the tip of the pen. You can only write two lines with one dip of ink.

Don't dip too much ink at one time, otherwise it will easily fall onto the paper and make an ink pimple.

Lin Yuzhu took the open handout and folded it over, and took a look at the words on it.

Song Yi's characters are just like the person he is. The characters he writes are sharp and vigorous, and there is perseverance between the horizontal and vertical strokes.

She picked up a pencil stub from the aluminum lunch box, turned over what Song Yi had written, and started to draw a simple diagram on the blank paper.

Song Yi moved a stool over and sat next to her, watching attentively as the pencil quickly sketched the lines of the mountains and terraces.

"The fields in Changkengwei and Baishi'ao are probably like this. Look at the location of these fields."

Lin Yuzhu used a pencil to circle the fields closest to the mountains, "These fields are constantly seeping water and flowing into fields lower than them. This area is all cold water fields."

Song Yi hummed and didn't answer. He looked at the picture and waited for her to continue.

Lin Yuzhu began to draw lines and mark.

"To treat these fields, you must first dig ditches. This is the main ditch, this is the branch ditch, and this is the side ditch. Their function is to drain water, lower the water level, and exchange the cold water for circulation outside to warm it up before returning it.

"

She tried to use the most popular language to explain the effects of supporting drainage, improving soil permeability, increasing soil nutrients, promoting rice growth and development, and increasing rice yield.

"Early rice cultivation should use a shallow front, medium roasting, and moist rear irrigation method, while late rice should use a front watering, medium roasting, and shallow rear irrigation method, which can improve the seed setting rate and the ability to resist lodging."

Song Yi was fascinated by what he heard, his eyebrows gradually relaxed, and there was a slight smile at the corner of his mouth.

Looking up at her serious explanation, her serious and confident demeanor pricked his heart even more than when she was acting coquettishly.

"Increasing the application of phosphorus and potassium fertilizers is the key to improving the productivity of cold paddy fields. Now that the rice seedlings have been transplanted, there is no time to apply calcium, magnesium and phosphorus-based fertilizers. If silicon-zinc fertilizers can be added as soon as possible, the situation of stiff seedlings can be greatly improved."

"But, 80% of the soil in our country is deficient in silicon and zinc fertilizers. Now these two elements are not taken seriously, so it is impossible to buy this fertilizer."

Lin Yuzhu drew a circle on the name of the fertilizer and found that the people next to her had no reaction.

When he turned around to look, he suddenly laughed angrily, "Am I good-looking?"

"Yeah." Song Yi responded in a low voice.

"Well, you're a big-headed idiot." Lin Yuzhu couldn't help crying, and reached out to pat his forehead, "I'm giving you some knowledge, but you're deserting. People like you have to be punished when they're studying, okay?"

Song Yi came back to his senses, cleared his throat with a hot face and embarrassment, "What did you just say you want to add now?"

"This!" Lin Yuzhu poked at the words on the paper with the pencil in her hand, "Our seedlings don't grow tall because the cold paddy fields are stiff for too long."

"Chemical fertilizer." Song Yi frowned, "We can't get the indicators for this kind of fertilizer."

I have never heard of this silicon fertilizer or zinc fertilizer.

Lin Yuzhu calmly leaned on the table and raised her eyebrows at him, "Of course you can't get it. We don't produce it at all in China now."

Today's fertilizer factories mainly produce nitrogen, phosphorus, and potassium fertilizers. Because the technology is immature and the cost is high, they are losing money selling fertilizers and rely entirely on subsidies to support the factories.

The production team can only approve very few chemical fertilizers, and they mainly rely on farmyard manure.

However, farmyard manure cannot meet the silicon fertilizer and zinc fertilizer needed by rice.

This is part of the reason why it was not until the 1980s that rice yields per mu slowly showed an upward trend.

Song Yi was silent for a while, "Then let's dig trenches first, and the yield per mu will be whatever it is."

He suddenly remembered something and looked seriously into Lin Yuzhu's eyes, "Can raising fish in the rice fields you mentioned really increase the yield per mu?"

"Of course." Lin Yuzhu closed the lecture folder, "You will know if you try it?"

Just as she was about to leave, she tapped her forehead, then suddenly sat down and smiled sweetly at him, holding her index finger and thumb in front of his eyes, "Captain, I have a small suggestion."

"you say."

"Look, our production team is so miserable that we don't even have time to do more side jobs."

"How else do you want to speculate?"

Song Yi pushed away the hand in front of him angrily and wanted to curse a few words, but felt that she had just taught him a lot of things and he really had no shame in scolding her.

If she always approves leave, other members will have objections, okay?

"I haven't said it yet. Do you know that this is prejudice?" Lin Yuzhu lay on the table lazily, holding the end of a pencil and poking at the handout folder unhappily, "Crossing the river and burning the bridge, bah!"

Song Yi looked at Lin Yuzhu, who only showed him the back of her head, and her petty behavior made him soften.

After raising his fingers several times, he finally restrained the urge to touch her head.

"Okay, I apologize. I was biased against you. Tell me what your suggestion is."

Song Yi's deep voice softened a lot. Lin Yuzhu turned her face and wrinkled her nose, "That's pretty much it."

She sat upright and looked at him with a smile.

"On a contract basis. For example, for our imminent trench digging task, you divide the work directly into areas, estimate how many days it will take to complete, and outsource it to the members...and then..."

"What did you say? Are you inciting to split the collective?!"

Song Yi got angry immediately. This kind of seriously wrong thinking must be criticized!

He raised his hand to slap the table, but Lin Yuzhu quickly held his hand down with quick eyes and hands, "No! Please don't go online casually, okay?"

She really wants to vomit blood

Song Gang's thoughts, which grew up under the influence of quotations, were frighteningly advanced.

"Calm down first, I'll analyze it for you and then you can slap the table, okay?"

"I know you are a little different from us now, but you can't forget your roots, you know!"

Lin Yuzhu felt that she had probably been scolded the most these days in her life.

But in order to get more free time, I can only show my weakest attitude and endure the most severe scolding.

After all, it is still very difficult to challenge the inherent model.

She slowly let go of his hand and looked up at him, tears rolling into her hair and her eyes red.

Just like the peach blossoms on a peach tree after the rain, raindrops will fall down as soon as you touch them.

"Song Yi, I want to ask you, in your eyes, am I such a selfish and ungrateful person? If so, then I have nothing to say to you and I will go back."

With tears rolling down her cheeks, she stood up, pushed away the stool, turned around and walked lonely towards the door.

Song Yi's fists loosened and clenched, his mouth formed a hard line, he took a deep breath and stood up and strode to catch up with her.

As soon as Lin Yuzhu touched the door handle, a rough big hand covered the back of her hand to stop her from opening the door.

She raised the corners of her mouth slightly.

He took several deep breaths and said in a rough voice: "I was speaking in a hurry. I didn't mean what you said. Please stop crying!"

He regrets it so much now, he shouldn't have said such excessive words and made her cry!

When she cried, his heart was in a mess and he really didn't know what to do.

Lin Yuzhu sniffed and her tears flowed even more fiercely, "Take your hands away, why are you so fierce when you say the wrong thing..."

Song Yi's soft and pitiful voice made Song Yi's heart tremble. After thinking hard for a while, he took her hand and carried it to the table, picked up the enamel jar and put it in her hand.

"Stop crying and drink hot water!"

Lin Yuzhu was so choked that she burped and almost couldn't cry anymore...

God damn drink hot water!
