Travel back to the 80s to farm

Although the weather in September is not as hot as in August, the temperature should not be underestimated!

Xialin Primary School had already started, so Shen Jing's classes were suspended. She joined the villagers in weeding the fields and occasionally took out the grain from the barn to dry in the sun! Life was quite fulfilling.

Today, Shen Jing and Lin Erya were learning how to sew shoe soles at Aunt Wang's house.

Aunt Wang's family lives a relatively comfortable life. Her son and daughter got married early, and her grandchildren are now seven or eight years old and are already in the first or second grade of elementary school!

It is not yet the autumn harvest, so the men go out to find work, while the women basically stay at home doing needlework.

"Shen Jing, so you are here!" Team leader Lin Jieping said anxiously as he pushed open the door.

"Captain, what do you want to talk to me about?" Shen Jing replied.

Lin Jieping was a little anxious: "Shen Jing, come with me to the rice fields and take a look!"

Shen Jing put down her needle and thread and quickly stood up: "Oh, okay!"

"Let's talk as we walk!" Lin Jieping led the way.

Along the way, Shen Jing learned that the rice in one rice field was shorter than that in the adjacent rice fields, and most of the rice ears were even hollow.

Shen Jing and Lin Jieping crossed a small bridge and saw a large area of ​​lush rice fields, which looked like a huge green carpet spread on the ground. However, Shen Jing was not in the mood to appreciate the scenery.

"Shen Jing, speed up!" Lin Jieping turned his head and urged.

"Mmm Good!"

Shen Jing quickened his pace and ran all the way, almost out of breath.

"Captain, not yet, haven't they arrived yet?" Shen Jing asked, panting.

"Soon."

"Wait, wait for me, I can't run anymore!" Shen Jing chased after him.

Most of the roads in the rice fields are muddy and narrow, winding, and covered with weeds. On both sides of the road are ditches for irrigating the fields...

Suddenly, Lin Jieping stopped and said, "Shen Jing, there is a puddle ahead. Take off your shoes! Let's wade across!"

As he spoke, Lin Jieping took off his shoes with thousand-layer soles and rolled up his trouser legs to his knees. Shen Jing hesitated for a moment, still afraid of leeches.

But he didn't hesitate for too long. He bent down, took off his shoes, rolled up his pants, and carried his shoes across the puddle in front.

"Shen Jing, it's just ahead! This piece of land is quite remote, so it's inevitable that we've neglected it during normal management. The rice has already blossomed and headed, so if we add some nutrients, we can get more ears! So today, I asked the people who manage the rice fields to spread some more fertilizer on the rice fields, and then I discovered this situation in this rice field."

Shen Jing listened silently, his mind already quickly searching for knowledge related to rice.

Shen Jing shouted to Lin Jieping in front of him, "Captain, when we get over there, help me pull out a few rice plants and show them to me!"

"Oh, okay!" Lin Jieping agreed readily.

After a while, Shen Jing felt sore all over and couldn't walk anymore: "Captain, how long will it take to get there?"

Lin Jieping responded: "Soon!"

Shen Jing complained in her heart: "Oh, this rice field is really remote! I have been walking for almost an hour and I am not there yet. Oh! My life is miserable!"

"We're here!" Lin Jie said calmly.

There were several men and women at the end of the field. When they saw Lin Jieping coming, they said:

"team leader!"

Lin Jieping nodded and said, "Yes!" Then he turned around and said to Shen Jing,

"Shen Jing, come and take a look at this land!"

Shen Jing carefully observed the rice field and found that the rice was indeed shorter than the surrounding rice.

"Captain, please help me pull out a few rice plants so I can take a closer look."

Lin Jieping called to a young man, "Jianguo, go pull out a few trees and show them to Shen Jing." The young man named Jianguo was Lin Jieping's nephew.

After hearing this, Lin Jianguo jumped down to the field and quickly pulled up a few rice plants.

Lin Jianguo smiled and handed the rice to Shen Jing: "Hey! Teacher Shen!"

"Well, thank you!" Shen Jing replied politely.

Shen Jing took the rice, looked it over from top to bottom, then broke open the stalks and understood.

Lin Jieping asked anxiously, "Shen Jing, what do you think is going on?"

"Well, if I'm not mistaken, this is rice black-streaked dwarf disease!"

As Shen Jing spoke, he took the rice to Lin Jieping and the villagers and said, "Everyone, please look! This diseased rice plant is shrunk, and the leaves are dark green and stiff. Observe the back of the leaves, the sheaths and the stems. Generally, the surface along the veins will show two conditions: one is waxy white in the early stage, and the other is short dark brown irregular protrusions in the later stage."

Lin Jieping took the rice and looked at it carefully. Then he turned around and handed it to a few villagers behind him and asked with concern:

"Shen Jing, can this dwarf disease you mentioned be cured? Will it affect the yield of rice?"

"Well, it can be cured, but it's unlikely based on current technology! The disease will also affect rice yields. Currently, the disease occurs before and after heading. Diseased plants are generally 12%-30% shorter than healthy plants. In addition, the rice on the ears will deteriorate, grow deformed rice, and taste bad!"

"So what can we do about this?"

Shen Jing said seriously: "What we need to do now is: first, block the disease and prevent it from affecting other rice fields; second, strengthen field management. Apply more phosphorus, potassium and zinc fertilizers to improve the stress resistance of rice, but avoid excessive application of nitrogen fertilizers."

"How to block it?"

Shen Jing thought to himself: "In modern agriculture, we can use 20 grams of rice drill to kill rice planthoppers and 20 grams of fungicide to prevent viral diseases, and spray them with 30 to 40 kilograms of water. But this kind of pesticide is not available in this era, what should we do?"

Shen Jing paced back and forth, and then thought: "Manpower to remove the diseased plants? That would require a lot of labor! Oh - we can only try our best!"

"Captain, if we want to cure this disease, we need to invest a lot of manpower! We need to conduct training and recognize the diseased plants! We need to cut the diseased plants in the rice fields in time, and check if there are any insect eggs on the leaves. We need to remove the eggs. Please don't feel sorry for the rice, but you can't have your cake and eat it too! There is no time to lose, Captain! Let's take action!"

Lin Jieping shouted loudly: "Jianguo, go to the team and call for help! Everyone who can come, come, don't delay, or something serious will happen!"

Shen Jing continued to explain: "Well, we also need to find someone to go to the county fertilizer factory to buy a few bags of potash fertilizer and phosphate fertilizer!"

Lin Jieping nodded: "Yeah, I got it! I'll ask Erdan to go to the county fertilizer factory to buy some tomorrow morning!"

Shen Jing is now holding the pulled rice to teach the people present how to identify diseased plants!

After the instructions were given, everyone rolled up their pants and got to work!

Among them, a woman in her thirties, Wang Cuihua, called out, "Teacher Shen, do you think this is the right one?"

Shen Jing nodded.

Lin Jieping also pulled out a few trees. "Shen Jing, you should come over here and take a look, right?"

"Yes!"

Shen Jing added: "Everyone should also carefully check the back of the leaves to see if there are any insect eggs, and crush them to death!"

Everyone said in unison: "Okay!"
