Hand over the farm system

"The lowest temperature in Jinghe on the 3th was minus 13°, and the highest was [-]°... that's too exaggerated!"

"Coordinate Shan Province, I wore two pairs of down pants when I went out today."

"I'm from Qinzhuang. It's been cold and humid these two days."

……

At 9 o'clock in the afternoon on the 23th, #中北雨灭了##中北气气# was on the hot list.According to the data of the Meteorological Observatory, during the period from September 30 to 3, the average temperature in Zhongbei is -15°-10°, and the lowest nighttime temperature in the west of Zhongshan Province and the north of Qinzhuang reaches -10°. -15°-[-]° is a normal temperature in winter, but now in late September, the sub-zero temperature is completely abnormal!

"Plant erosion, reduced respiration and photosynthesis definitely affect air temperature."

"Not only does it affect the temperature, but the acid rain disease in Mali is caused by excessive sulfur dioxide in the air and lack of oxygen."

"Holy shit, does oxygen rely on plant photosynthesis?"

……

Acid rain corrodes soil.In the past five months, residents have focused on the food crisis. They thought that everything would be fine if they solved the food crisis, but now, global ecology and global oxygen supply are also serious issues.

"We won't have acid rain disease, right?" some netizens asked worriedly.According to international media reports, 23% of Mali residents have respiratory problems such as rapid breathing and chronic pharyngitis.

Excessive sulfur dioxide will affect human respiration.Now the sulfur dioxide has increased, and the oxygen in the air has decreased... Everyone combined the two, and the scalp instantly went numb!

"My throat was quite itchy before. Is it a sign of acid rain disease?"

"Is acid rain disease contagious?!"

……

Netizens desperately breathed.Air is the most normal substance, if you don't breathe it deliberately, you won't notice it at all.Now that the global acid rain problem has emerged, everyone feels that air is also a very precious resource.

"Can you make a home oxygen bar?"

"Does the online oxygen bottle tube work?"

"I'm going to buy some green plants, green radish or oil wheat?"

……

In the next five hours, key words such as #How to Build Family Oxygen Bar##全球病氧危险# continued to rise.In addition, orders related to Longbao hydrogen peroxide and portable oxygen tanks increased simultaneously.

The temperature drop in Zhongbei has given everyone a wake-up call. The global acid rain, they are not only facing a food crisis and a vegetable crisis!

……

"70% of the vegetation was affected by the heavy rain in the seven provinces this time, and several underground bridges in the mountain province were flooded..."

While the whole country was paying attention to the disaster situation in Central and North, Liu Wensheng said with a tired face in Fengshan Farm.According to Long Xia's data, there were no casualties in this disaster, but large-scale freezing injuries occurred.Freezing damage Freezing damage is a unique disaster in extremely cold weather. Now freezing and acid rain have increased the corrosion rate of plants in North China several times.

"I still can't compete..." Liu Wensheng was a little annoyed.In fact, since the torrential rain in March, Long Xia has been rehearsing the harm of acid rain.

Food crisis, vegetation degradation, water ecological pollution, oxygen reduction... These are all possible hazards of acid rain.This year, in addition to researching food, Long Xia also reached cooperation with research institutes in various provinces and cities to protect a certain number of rare animals and plants in advance.Long Xia had been preparing for this disaster, but the disaster came too fast and too violent, and the consequences were more terrifying than the preview.

After Liu Wensheng vented his emotions, he said to Qin Yun, "I'll go back for a few days."

Although the torrential rain in central and northern China did not cause casualties, it did great damage to animals and plants. He had to go back to deal with some post-disaster work.

At three o'clock in the afternoon, Liu Wensheng left, and Qin Yun looked at the ten thousand mu of farmland in a daze.

As soon as he received the news of the disaster in Zhongbei, he remained silent.In my previous life, I was reborn on July [-]th, and what impressed me most was the global food crisis.After his rebirth, he has also been dealing with the food crisis.I naively thought that solving the food crisis would solve Long Xia's dilemma.

But after a year of preparation, he realized how ridiculous his idea was.Food is only a part of acid rain hazards. He is confident in solving the food crisis, but the plant crisis, nutrition crisis, oxygen crisis... any crisis here is like an insurmountable mountain.

Long Xia worked hard for a year and temporarily solved the food crisis, but next...he was not sure if he had confidence.

"Secretary Qin?" In a daze, a young man came over.

"Assistant Zheng." Qin Yun got up and greeted.The man's name is Zheng Hairui, an assistant to academician Zhou Yuanheng, and he is mainly responsible for some itinerary and recording work.

"Didn't go to the rice fields?" Zheng Hairui asked.Now the hybrid rice is entering a critical moment. Before this time, Qin Yun would observe the rice in the field.

Qin Yun smiled: "I'll go later."

Zheng Hairui didn't suspect him, and handed Qin Yun a small package: "This is the letter for this month."

Since the successful research of Fengshuang 003, residents also know that Fengshan Farm and Longxia are in a cooperative research relationship.Since then, the farm has received letters from all over the country, and these letters will be sent to Lushui Township, then screened by liaison officers and sent to the farm.

Qin Yun took the packet, which contained more than 20 letters.

"I'll go there first, I'll be here later." Zheng Hairui waved his hand and left.

Qin Yun sat on the ground and opened the letter.

"Hello, I am a high school student in Lanmei County, Jiangxi Province. My family has planted weathered corn this year, and I look forward to a good harvest next year."

"Thanks to the scientific research uncles for their research, Longfeng wheat is delicious, and Zhongzhi sweet potato is also delicious..."

"I've been looking forward to Zhongzhi Potato Flour, and hope that Zhongzhi Potato Flour will be on the shelves again."

……

Xianfengshan Farm is still synonymous with Mysterious Farm.Netizens speculated that Fengshan Farm should be a research base established by the national scientific research team, which can also explain many acid rain seeds such as Longfeng 001 and Zhongzhi 002.

90% of the guesses of netizens are consistent. Based on this guess, there are also many thanks to the scientific research team in the letter.

Qin Yun read it one by one, and at the end, it was a hand-painted drawing by a child.In the picture is a golden ear of wheat, a seven-year-old boy is holding the ear of wheat, the sun is drawn in the upper right corner, and six big characters of "Thanks for the farm food" are written in the middle.

Qin Yun is not used to expressing, but looking at the crooked six characters, he couldn't help being fascinated.

The Agricultural Research Group, the Biology Group, the Farm System Analysis Group... At this time, each group is doing its own work, and everyone has a firm gaze, and they have not had any bad emotions because of the Zhongbei news.

Qin Yun recalled Zhou Yuanheng's interview again: My body can last for another two years, but Long Xia can't live without food for a day.With one more day of research by the team, Long Xia may be able to solve the food crisis earlier...

For scientific researchers, there is nothing impossible, they will only look for opportunities amidst many difficulties.

Qin Yun put away the envelope.Today, October [-]nd, he no longer has the ability to predict foresight, but the food crisis in July can be resolved, and then, as long as he doesn't give up, everything is possible.

In the next three days, Qin Yun adjusted his state and continued to study rice diligently.

.........

"Can it be saved?"

"Apply some wound medicine, and don't get wet for two days."

While the farm was operating normally, Zhao Chuangang looked at the animals in front of him in Chang'an Mountain Safari Park with distress.This is a one-year-old emu. Half of the emu's left wing is black, which is caused by the inflammation caused by the previous wound and acid rain.

Zhao Chuangang bandaged the emu's wound and looked outside worriedly.He had been worried about the zoo being flooded before, but now the zoo is not flooded, but a more serious phenomenon has occurred. The trees and soil in Chang'an Mountain are covered with frost... This is the chilling damage caused by the low temperature of the plants.

The Chang'an Mountain Zoo covers an area of ​​70 mu, [-]% of which are natural forests. When he came to see it, at least [-]% of the forests suffered from chilling injuries.This is a forest area of ​​nearly [-] mu...
