Chapter 1736: No Path of Survival!

At 1:30 PM, the ice and snow began to melt, and at 3:00 PM, the high-level blight-evolved nematode disaster relief program was launched. By 4:30 PM, all farmland in the northern district planted with crops had been sprayed with the symptomatic special-effect agents urgently prepared by Zhang San's team, causing the activity of the high-level evolved nematodes and blight-evolved Clostridium in the soil to drop significantly and die off.

The leaders couldn't spare a moment to catch their breath and immediately started spraying the farmland where overwintering wheat hadn't been planted. There were also a large number of high-level evolved nematodes in these fields. If they weren't killed as soon as possible, these nematodes would eat up the plant residues in the soil and then spread outward, endangering the crops in the surrounding farmland.

Until 9:30 PM, after monitoring confirmed that the disaster situation of high-level evolved nematodes in all cultivated land had been contained, disaster relief commander Zhang San announced that the emergency disaster relief in the territories of Northern District 1 had ended, and each territory returned to a normal state.

The exhausted leaders stood by the farmland, staring blankly at the disaster-stricken farmland, unable to recover. Just then, they heard the sound of the single-soldier aircraft taking off again.

The disaster relief in Northern District 1 had ended, but the high-level evolved Salmonella in Mountain 50 hadn't been completely killed. This was the third time Xia Qing had flown away from the territories of Northern District 1 this afternoon, rushing to the pollution area of Mountain 50.

Zhao Ze, who was tearful, cheered himself up and pressed the walkie-talkie button, "Territory 7, is anyone there?"

Zhang Zhang Jingwu went online, "Yes."

"Zhang-ge, I'm Zhao Ze from Territory 4. I led the team to dig the drainage ditch outside the danger zone of Mountain 50. The disaster situation in my territory has been contained. Do I need to go to Mountain 50 to patrol for dangers? I can set off now."

"Wait a moment."

The agent of Territory 7 had just finished speaking when Tang Huai went online, "Zhao-ge, I'll drive you over." He didn't want to miss any opportunity to go out in a team.

Di Ming followed closely, "Zhao-ge, I'm responsible for your safety." He had just returned from the eastern coastline and wanted to go to Mountain 50 to see the giant tiger.

Wen Lord Wen Nengjie went online, "Zhao-ge, I'm busy here too, I can follow along to carry supplies." The loss of wheat fields was too great, and he wanted to go out to participate in missions to earn points to recover his losses.

Shi Du followed, "I'm going too, I'm full of energy now and can execute missions." Territory 10 hadn't discovered high-level evolved nematodes and was the territory with the least disaster relief mission volume among all territories in Northern District 1.

Soon, disaster relief commander Zhang He went online, "Zhao-ge from Territory 4, I'm Zhang He. Xia Qing has already gone to patrol the drainage ditch of Mountain 50. If reinforcement is needed, she will contact you."

"Received." Zhao Ze responded. He should have gone online to apply earlier, so that Xia Qing could have run one less trip and rested in the territory for a while. Only when Xia Qing was in Territory 3 did Zhao Ze feel safe.

Qi Fu went online to ask, "How much wheat seedling did everyone lose? I have five sheds affected here, and only one-third of the wheat seedlings in the sheds are left. I don't know if the rest can survive the first Qi-rain."

Tan Qi went online, the little girl's voice was hoarse, "We lost six sheds."

Wen Lord Wen Nengjie went online to complain, "I lost eight sheds here, and the remaining seedlings in the fields are also about one-third. My heart hurts, and the brothers in the territory have been busy all winter. Now that spring is here, they have to follow me and eat rations."

Tang Huai went online, "Shi Du, hasn't your side discovered high-level evolved nematodes yet?"

"Haven't discovered any yet, the three of us are all terrified. I'm sampling and will send it over for testing in a while." Shi Du tried his best not to make his voice sound too relaxed, so as not to be envied.

Zhang San went online lazily, "Shi Du, no need to send it for testing. In principle, high-level Qi-evolved nematodes won't appear in Territory 10."

Shi Du immediately answered happily, "Okay, thank you San-ge, now my dad can rest assured and go cook dinner."

It was almost 10:00 PM. Everyone was relying on freshly squeezed spinach juice or nutrient solution to hold on and hadn't eaten dinner yet.

Zhu Li seized the opportunity while the big boss was in a good mood to go online and ask for advice, "Brother San, high-level blight-evolved nematodes did not appear in Territory No. 10, and the evolution and activity of the anaerobic Clostridium are also relatively low. Is it because Territory No. 10 is newly reclaimed farmland?"

The activity of anaerobic bacteria in the evolved forest and uncultivated areas in the territory was significantly lower than that in cultivated farmland, which everyone knew.

Territory 10 was now the former Territory 14. Its leader, Yan Meng, hadn't seriously performed his duties as a leader. He had lived in the territory for nearly two years, and the reclaimed area was less than two acres. Even the reclaimed area was just clearing wild grass and sowing seeds, without fertilizing at all.

The Shi family of three only moved to Territory 14 in the second half of last year, reclaimed farmland, built large sheds, and planted crops, so the nitrogen content in the soil of their farmland wasn't high.

Zhang San responded with a sound and introduced the situation of this insect plague in detail to the studious Zhu Li, "Preliminary testing confirms that the biggest incentive for the high-level blight-evolved root-knot nematodes to be spawned after this anaerobic Clostridium evolved is the excessively high nitrogen fertilizer in the farmland soil. The high-nitrogen environment leads to a drop in soil pH and an increase in anaerobic bacterial metabolic substrates, causing the upregulation of its virulence factor expression..."

Huo Zhun in Territory 11 became more confused the more he listened. While clearing the dead wheat seedlings, he accidentally pulled out a good seedling, which made his scalp tighten with fear. He hurriedly stuffed it back into the soil, and then turned to peek at his father, only to meet Di Ming's annoying face...

After Zhang San introduced the situation, soil research department members like Zhu Li, Ye Yang, and Tang Heng went online to analyze this insect disaster. Half an hour later, the allies finally understood the inducement of this insect disaster, and their moods became even heavier.

Nitrogen fertilizer is an indispensable fertilizer for crop growth. Crops won't grow well without nitrogen fertilizer, and anaerobic bacteria will evolve if nitrogen fertilizer is used. What should they do?!

Xia Qing, who had returned to the territory from Mountain 50, listened for a few minutes and went online, "We need to calculate the fertilizer requirements for each crop more accurately and fertilize precisely."

Wen Lord Wen Nengjie immediately went online to brush his presence, "It has to be Qing-Zhao Jie, she grasped the key point immediately!"

Tang Huai went online, shouting noisily, "San-ge, I just got news that the 18,000 acres of overwintering wheat in the safety zone planting center were all destroyed by the insect disaster. The insect disaster in the safety zone is serious, also because of the high nitrogen fertilizer content, right? The land in the safety zone has been planted for eleven years."

Everyone waited for a full thirty seconds, but didn't hear Zhang San answer Tang Huai's question.

Tang Huai transferred the object of his request for help, "Qing-Zhao Jie, is it because of this reason?"

Xia Qing was a middle-level manager of the Agricultural Department, so she had of course received the news that Tang Huai could receive, "It's not just the nitrogen fertilizer content. The copper ion content in the soil of the safety zone farmland is too high. In order to deal with copper stress, the anaerobic bacteria evolved a stronger metal transport system, strengthening their toxin secretion ability, so the disaster situation there is more serious."

Hearing Xia Qing answer professional questions, Zhang San, who was eating dinner, smiled.

Shi Du followed up, "Qing-Zhao Jie, how can there be copper in the soil of the safety zone farmland?"

Xia Qing, who had just entered the house, handed the Sheep Leader a handful of fresh green-light dragon fruit dried, said hello to the two melons and one monkey in the tree nest, and pressed the button again, "Because in the first three years of the natural disaster, the fungicide used by the safety zone planting center was Bordeaux mixture."

Shi Du asked, "What is Bordeaux mixture?"

Zhu Li answered immediately, "Bordeaux mixture is a fungicide commonly used in agricultural planting before the natural disaster, mainly used for mildew prevention and anti-fungal..."

After popularizing what Bordeaux mixture was, Zhu Li asked Xia Qing for advice, "Qing-Zhao Jie, isn't it that only organic fertilizer and organic medicine are used for farming after the natural disaster? Why would the safety zone's planting center use this to kill bacteria?"

Xia Qing explained, "Bordeaux mixture belongs to inorganic copper-containing fungicides, but it was a fungicide allowed to be used in the 'Organic Agriculture Permitted List' before the natural disaster, so it was abbreviated as 'organic fungicide'. In the first few years of the natural disaster, there was a shortage of professional talents in all aspects of our country, and the people managing the planting center lacked professional knowledge, resulting in conceptual confusion."

Tang Huai went online immediately, "Sure enough, a famous teacher produces a brilliant student. Qing-Zhao Jie is worthy of being a graduate student specializing in crop-soil collaborative improvement research personally brought by San-ge!"

Xia Qing...

Zhu Li followed up immediately, "Qing-Zhao Jie is so busy and still working hard to learn, she is truly awesome. I want to follow your example and reasonably use fragmented time to learn useful knowledge!"

Huo Zhun...

Shi Du...

It's over, there's no path of survival!

Their junior high school graduation certificates hadn't been obtained yet, and Xia Qing had already become a graduate student of the big boss! ===== CHAPTER 1737 =====
