This news, like a heart-booster, brings new hope to people who need to line up in the sun for a while, and do not want to speak until they have to, so as not to lose their physical strength.

Almost everyone is talking about snow vegetables:

"See the photo posted at the door of the second floor? I heard that it was filmed by a drone, and many of these dishes grew in the snow, and it was immediately delicious. ”

"I know this dish, Wutai Cai! In the past, my hometown planted pigs to feed, but now it has become a luxury to eat a bite. ”

"It's coming! Wait a little longer for a month and you should be able to eat, look at the photos and look at the photos that look not less, each person can't get half a piece, how can you have a few leaves? ”

“……”

Ordinary people are concerned about finally being able to eat a bite of fresh vegetables, and government leaders get together to study how these vegetables come out.

Although the seedlings have been tested and found to be non-toxic and edible, the fact that the source is unknown has always raised doubts among policymakers.

“…… Not only in our city, but also in the surrounding area, it seems to have appeared overnight. ”

"In this way, it should not be artificial. In this kind of weather environment, individuals do not have such great ability. If it's a group...... With such a large coverage, our drones have been patrolling all the time, and any anomalies have long been discovered. ”

"Definitely! What's more, at this time, if you have seeds and can grow vegetables to improve your diet, it is not an exaggeration to call him/her a 'hero', so why do it secretly? Isn't it more convenient to hand it over to the government? So I think it's naturally grown. ”

"I also think it's not man-made, I'm afraid it's the adaptation feedback of the species in extremely cold weather. Isn't there a saying in the biological world called 'survival of the fittest'? ”

The leader pondered for a moment and asked the secretary: "The south and the north have not found these two dishes until now?" ”

"Yes, only we have this part of the Central Plains."

That's weird.

A fingertip tapped on the tabletop, puzzled.

Someone suddenly thought: "Could it be that the temperature in our Central Plains is just right for the growth of these two vegetables?" ”

It makes sense when you think about it.

The temperature in the north is so low that it is explosive, and the specific cold weather experts can't predict.

The humidity in the south is high, and as soon as the snow freezes, the crops have long froze to death.

The Central Plains is relatively better, the minimum temperature is still hovering around minus 30 degrees, the climate is dry and the snow is relatively fluffy, and the seeds that are resistant to cold and low temperature are wrapped in snow and germinate......

Discussion and discussion, it seems that this point of view is the most reasonable.

The first leader asked the secretary to sort out the meeting materials and report them to the headquarters in a while.

"By the way, you're still in touch with the anonymous emailer, right? Ask him/her if he or she needs fresh vegetables. ”

When Xu Yingying, who did good deeds without leaving a name, went online that night, he found an email from the Secretariat of the Municipal General Office lying in the mailbox, and twitched the corners of his mouth after reading it.

Does this really want to repay her contribution or do you want to take the opportunity to find out her address?

No matter which one it is, is my sister a person who lacks one or two greens?

Immediate reply: No, thank you!

At that time, the first leader listened to the secretary's relay thoughtfully: No need for green vegetables after being frozen for more than three months? In this way, the other party is either not an ordinary person, or ...... Are you a resident of the Southern Hemisphere?

Only the southern hemisphere is not covered with snow and ice, but everywhere looks like the height of summer, and the Antarctic icebergs are said to have melted several times.

Under the high temperature radiation, people have difficulty traveling, and the mortality rate caused by heat stroke is a terrible number. Many houses in high latitudes are not air-conditioned, and the temperature climbs to 40 degrees Celsius and has to be moved underground.

But those heat-tolerant and heat-tolerant vegetation are like heaven, and their roots absorb the snow water melted by Antarctic icebergs, and they have swayed several centimeters overnight.

Countries in the southern hemisphere are considering that if the temperature is perennial from now on, they plan to build aerial homes with towering trees, develop private aircraft, and open up flight routes.

It's all on Earth, but the gap is so big.

It is as if the earth is divided into two worlds by enchantment, drought and waterlogging.

But it is unrealistic to say that the whole country is moving to the southern hemisphere.

The disease and mortality caused by high temperatures are not low, and in some areas, the plague is raging because it is not sanitized in time.

What's more, the anonymous email mentions that the extreme cold will enter the high temperature after two or three years, when the global high temperature sea level rises, wildfires, tsunamis, diseases and other disasters will come one after another, and there will be no more peace in the southern hemisphere.

It is better to expand the underground base, improve the living environment, and try to survive the extreme cold and high temperature in the past few years, in order to protect as many human beings as possible, and pass on the torch from generation to generation.

Xu Yin replied to the letter and continued to browse the news.

The network system in various places is good and bad, and the information is intermittent and incomplete.

So she "climbed over the wall" and connected to the news network of a country in the southern hemisphere.

Speaking of which, this "circumventing the wall" technique was taught to her by Comrade Xiao Jin, and it really worked at the critical moment.

Xu Yin went on the net for a while and somewhat understood what the current situation in the southern hemisphere was under the cover of high temperatures.

In two years, the northern hemisphere will not be immune to this situation, and it will be even worse than that. Because of the extreme cold for two years, supplies have been extremely scarce.

Unlike in the southern hemisphere, where high temperatures also induce disease and death, tropical crops are relatively easy to grow than in extremely cold weather.

Thinking about it this way, we still have to grow our fields and accumulate grain to prepare for the follow-up.

Xu Yin put away the computer, looked at the probe, and saw that the friends were sleeping soundly, tiptoeing to the minus five floors, pushing open the escape door of the equipment room, and going out was another bunker that the robot had built day and night.

It's just that it's different from the bunker they live in now, not only is it big, but each layer is a planting area, and the soil is the nutrient soil that she had prepared for a rainy day in her last small world, and in order to improve the survival rate, it was also mixed with a little bit of Taoyuan Star's Breath loam.

There is a patio surrounded by a guardrail between the blocks, the natural diffuse light input from the lighting system can illuminate each floor through the patio, a set of automatic irrigation equipment is installed at intervals next to the guardrail, and a fine hot spring stone is placed at the water outlet, and the temperature of the sprayed water is kept at around 16 degrees.

According to the different light and irrigation intensity, she put up a sign for each area, writing the type of crop, the floor and area with abundant sunlight and high irrigation intensity are used to grow rice, potatoes and corn, and the sunny area does not need frequent irrigation to grow wheat and cotton; Even if there is a patio, there is no sunlight in the shady area, planting fungus cabbage, Chinese cabbage, milk cabbage, mustard greens and other shade-loving crops; Negative 10 or even deeper dark, warm and humid areas are used to propagate fungal crops.

She recorded the experience of building and planning the "greenhouse", improved the defective areas, and created a livable environment for temperate and subtropical plants little by little.

As for tropical crops that are resistant to high temperatures, there will be opportunities to plant them in two years, so there will be no waste of limited space in the "greenhouse".
