Wei Daquan's family is not well-off. He has spent his whole life digging for food from the ground with his face turned to the loess and his back to the sky, but his life has become worse and worse. Most of the land in the village that could be barely cultivated has become increasingly desertified in the past few decades.

The desertification of the cultivated land has worsened to the point where even pasture cannot be grown, and the whole family can only survive by doing odd jobs in nearby towns.

But since the birth of the grandson, there are more mouths to eat in the family. It is difficult to support the family with just the money earned from odd jobs in the small town. The son has no choice but to abandon his wife and children and go out to work in a distant city.

By October last year, this kind of desert sweet potato, which was said to be researched by two of the most powerful professors in the country, suddenly became popular in the surrounding villages. One hundred packets of seeds were sold out in just half a day. Wei Daquan was lucky enough to grab them.

I got a pack and planted it in my four acres of severely desertified land at home.

This kind of desert sweet potato is easy to take care of. You only need to pour it with a nutrient solution diluted at a ratio of 100:1 once a week. A bottle of nutrient solution only costs a few dozen yuan, but it can be used for three months after dilution, which is enough to last until this time.

Desert sweet potatoes bear fruit in an acre of land.

Wei Daquan has calculated that if this desert sweet potato is as magical as others say, he can earn at least 5,000 yuan from his four acres of land!

Relying on four acres of useless desert land, I made nearly 5,000 yuan in three months! This was a good thing that was unimaginable in the past!

If all this is true, then my son no longer has to travel so far away to work. He can grow dozens of acres of desert sweet potatoes at home with himself, and the money he earns by then is only a fraction of the money he earns from working in other places.

More or less, there is no need to separate the flesh and blood of the son and grandson.

So Wei Daquan went to the fields to see the growth of these desert sweet potatoes almost every day after doing odd jobs. These four acres of wasteland became the hope for Wei Daquan's family to increase their income and give them some hope for their future life.

Seeing the deserted land where even pasture could not be grown, green buds sprouted up and stretched into a patch of green vines. All the deep wrinkles on Wei Da's face relaxed, and his confidence in a better life in the future became stronger and stronger.

More and more.

But the good times did not last long. It was less than a month before the sweet potato harvest. An unprecedented cold wave suddenly came. The temperature began to drop sharply from December. By mid-to-late December, continuous cold waves

The blizzard dyed the entire area hundreds of miles white.

The bad weather caused Wei Daquan's family to lose their livelihood, and they had to rely on the grain they had stored to survive. After the temperature dropped below -20°C, Wei Daquan no longer dared to have much hope in the desert sweet potatoes he planted.

.

It’s not like he has never planted sweet potatoes before. He has never heard that sweet potatoes can survive below 0℃, let alone -20℃. Moreover, he hasn’t watered the nutrient solution in the past month, and he doesn’t know if sweet potatoes can survive from the soil.

Getting enough nutrients?

His only reason to cheer himself up is that this magical desert sweet potato really does grow in the desert after all. Maybe it can withstand ultra-low temperatures below -30°C as rumored?

Today, the temperature has stopped falling and has quickly climbed to around -6°C. Although the snow has not yet melted, Wei Daquan can't hold it anymore. He wants to push aside the snow to see if the desert sweet potatoes under the snow are still there.

Survive.

It was noon, and the sun was shining warmly, but the howling north wind still brought a biting chill. Wei Daquan used his palms covered with thick calluses and countless cracks to carefully push away the thick calluses.

Thick snow.

Slowly, he finally saw a touch of green.

Yes, it is green, not the dark green that is frozen and has a grayish smell, but the emerald green that is full of life!

Wei Daquan was so excited that his hands were shaking a little. His movements became gentler and more careful, and he finally managed to push aside a large area of ​​thick snow, and finally he could see clearly!

The emerald green leaves showing infinite vitality, the yellow sandy soil, and the white snow are intertwined together, making it particularly conspicuous.

Still alive!

The desert sweet potato is alive! And alive and well!

Wei Daquan was enveloped in huge ecstasy!

It’s true, everything in the rumors and propaganda is true, there really is a miraculous sweet potato plant that can survive and live well at -20°C!

He suddenly remembered something. It has been almost four months since the seeds were sown. I wonder if the sweet potatoes have grown?

Wei Daquan continued digging into the sand with the hope of being safe.

Because the sandy soil is moistened by ice and snow, it rarely has enough moisture.

Wei Daquan soon dug out hard, round potato cubes. With his heart pounding, he continued digging, and soon he dug out a large bunch of half-grown sweet potatoes.

Sweet potatoes are only the size of a baby's fist, but judging from the heavy fruiting rate, once fully grown, they will weigh at least more than ten kilograms. In this way, it is estimated that one acre can produce 3,500 to 4,000 kilograms! Earning 1,500 yuan per acre is not a dream at all.

!

At this moment, the tears in Wei Daquan's eyes turned into two lines of tears of joy, and his chapped lips kept opening and closing, saying "thank you" vaguely.

Thank you to the country, and to the two young professors who created this perfect desert sweet potato!

At the same time, he held the little sweet potato tightly, as if he was holding the foreseeable bright future of his family!

…

Not only Wei Daquan, but many botanists and scholars who have been paying attention and trying to grow the perfect desert sweet potato are also doing the same thing.

The country is determined to fully promote this perfect desert sweet potato in the desert edge areas, but can this perfect desert sweet potato really achieve 100% of the growth indicators in the laboratory, and can it really withstand the extreme hot and cold weather?

?

Even though Qin Ke and Ning Qingyun have always been famous for creating miracles and are world-renowned great scientists, there are still a lot of people who are a little skeptical about the perfect desert sweet potato.

This chapter is not over yet, please click on the next page to continue reading! For the sake of caution, the country must have the results of pilot planting to increase persuasiveness and confidence in decision-making before fully launching the large-scale promotion and cultivation of perfect desert sweet potatoes.

When all the pilot areas sent back their reports, everyone breathed a sigh of relief. The Perfect Desert Sweet Potato handed over an answer that was extremely shocking, but extremely satisfying!

In extreme cold conditions, with temperatures falling below -20°C, and being completely covered in snow, the perfect desert sweet potato still survives tenaciously, and its growth only becomes slower, which does not affect the subsequent fruiting rate. Once the temperature rises,

, re-watered with nutrient solution, the perfect desert sweet potato resumed its growth rate!

The moment they saw the trial planting report, countless people shouted excitedly in their hearts - God bless the Xia Kingdom, God bless the farmers! The stars will always be there, and the Xia Kingdom will be prosperous!

The news media, which has always had a keen sense of smell, quickly dug up these news, and knowing that the country planned to promote this perfect desert sweet potato, news articles full of praise were soon published, and then relied on

Newspapers and Internet channels are spreading rapidly!

"Although winter is still full of high-spirited greenery, the perfect desert sweet potato has successfully withstood the severe cold test!"

"The results are gratifying, the perfect desert sweet potato has taken root on the edge of the desert!"

"Unparalleled scholars in the country, once again pay tribute to Professor Qin Ke and Professor Ning Qingjun who developed the perfect desert sweet potato!"

"The brightest green of life in the snow! - Detailed records of the pilot area of ​​the perfect desert sweet potato!"

"The food crisis in desert areas has been effectively dealt with, and the perfect desert sweet potato will be promoted and planted in all desertified lands nationwide!"

Teachers and students in the biology departments of many universities had previously snapped up small packages of perfect desert sweet potato seeds on the Internet, and now they were also taking photos and videos of the experimental planting results to join in the fun.

For a time, the popularity of #Perfect Desert Sweet Potato Linghan Blooming even suppressed the #Meteorological Department’s announcement that the coldest winter in recent decades has passed.

Compared with the hustle and bustle on the Internet, other news that has not been widely reported is more significant.

Dozens of desert countries came after hearing the news, and then, accompanied by relevant personnel from Xia State, they took a trip to the pilot area on the edge of the desert. When they personally shoveled away the thick snow with small shovels, they saw the smear of snow.

When the green color was full of vitality and vitality, I kept saying "it's incredible", and then spared no effort to introduce this magical desert sweet potato into my country.

The final agreement reached by Xia State with these countries has not been announced to the public, but it is said that it involves in-depth cooperation in many fields such as oil, minerals, food, etc. Xia State has also successfully won the friendship and respect of these countries, and has gained international recognition.

Prestige and status skyrocketed.

…

Time has arrived in late January amid such hustle and bustle, and there are still more than ten days before the Spring Festival.

Qin Ke and Ning Qingyun were in the Fluid Mechanics Laboratory of Qingmu University instructing everyone to conduct extreme weather simulation experiments. Principal Huang Ruide personally called and invited Qin Ke and Ning Ke to sit in the principal's office.

Qin Ke and Ning Qingyun were both a little surprised, but when Principal Huang called, they still had to give face.

The school had already sent a car waiting downstairs, so there was no need for the two of them to brave the cold wind and walk there.

When they arrived at Principal Huang's office, they saw that Vice Principal Gu Bojun was also there. Qin pulled Ning Qingyun and said hello with a smile: "Hello, two leaders!"

The two principals stood up to greet each other, with spring breeze-like smiles on their faces: "Xiao Qin, Xiao Ning, sit down, I have two things I want to talk to you about."

There were no outsiders in the office. The two principals and Qin Ke were very familiar with each other. They did not call them "Professor Qin" or "Professor Ning" politely. Instead, they kept the usual familiar tone of speaking between elders and juniors.

Qin pulled Ning Qingyun and sat down. Vice Principal Gu Bojun filled tea for the two of them, and Principal Huang handed over an invitation letter.

"This is an invitation letter from the World Cultural Council. Normally, we refuse the invitations for you two according to our previous agreement. However, this invitation from the World Cultural Council is more important, so you should come in person.

Decide."

Qin Ke took it and opened it, and saw that the World Cultural Council had invited the two of them to participate in the "Einstein Science Prize" selection meeting held in Sweden in March.

The "Einstein Science Prize", whose full name is the "Albert Einstein World Science Prize", is named after the great scientist Einstein. It is a famous world science award, sponsored by the World Culture Council.

The association is established, selected and awarded, with the purpose of encouraging and commending outstanding scientists who have made significant research achievements in the world's science and technology fields and brought benefits to mankind.

Its selection committee is composed of more than 100 world-renowned scientists from 50 countries and regions, including many Nobel Prize winners. The selection process is also very rigorous, making the "Einstein Science Prize" a

The world-renowned international award.

The "Einstein Science Prize" is awarded only once a year to one person at a time. The award includes a certificate, a commemorative medal and a bonus of US$10,000.

Principal Huang smiled and said: "We have consulted the opinions of the superiors. The superiors believe that this award is of great significance and hope that you will strive for it. Moreover, after comprehensive research and judgment, your current main academic achievements are concentrated in the theoretical direction. You will encounter difficulties when going abroad.

The probability of danger is very low, and the country will make complete arrangements to ensure your safety. What do you think?"

"Switzerland..." Qin Ke and Ning Qingyun exchanged glances and quickly made a decision: "Okay, then Qingyun and I will go abroad, just in time to visit the Royal Swedish Academy of Sciences and receive the foreign academician certificate.

.”

Gu Bojun suddenly stood up and said excitedly: "Foreign academicians of the Royal Swedish Academy of Sciences? Have you received relevant invitations?"
