The third team in Wei Xueming's team works very responsibly. They have found all 127 kinds of sweet potato seeds whose names can be found in the world. They have been studying sweet potato hybrid breeding technology for more than half a year and have achieved many results.

The other two results are also good. Qin Ke is very satisfied with them and has said that this year's year-end bonus will be doubled, which makes all researchers excited and cheering.

They are currently all regular employees of Qingning Technology, and they also receive special subsidies for scientific researchers. Their salaries are so high that they are definitely the first among all plant research laboratories in the country, and the working environment is very comfortable and typical.

The work system with clear rewards and punishments makes everyone more enthusiastic about work.

Qin Ke could also see that general manager Zhou Shutao was indeed a great talent in management. Wei Xueming's shortcomings of not being good at management but only good at research were made up for by Zhou Shutao's rules and regulations.

For this reason, Qin Ke specially called Zhou Shutao and praised him.

Of course, for Qin Ke, the most important thing is that these 127 kinds of sweet potato seeds, as well as the second group of special fertilizers and special protective agents that have just been successfully researched, have been successfully projected into the "Plant Plant" of the "Virtual Scientific Research Experiment Center"

In the "breeding laboratory", there are more than a dozen pieces of land with different fertility status projected in it, as well as various microscopes, incubators, temperature controllers and other equipment, which are enough to complete the cultivation of this new type of desert sweet potato.

On the way back to school, Qin Ke unexpectedly received a new system task.

"Dingdong! The mission of the God of Learning has been updated: 'Cultivation and promotion of new desert sweet potatoes'!"

"Third, let's cultivate and promote new desert sweet potatoes: Scientific research is meaningful because it benefits mankind! Please host the new desert sweet potatoes based on the knowledge in "Cultivation Methods of New Desert Sweet Potatoes" and promote their cultivation! Requirements

:The new desert sweet potato has been recognized by the market, with a planting area of ​​more than 10,000 hectares.”

"Task reward: 500 technology points (cross-breeding)! An additional mysterious gift pack as an additional reward!"

It actually awarded a full 500 points for cross-breeding technology! Qin Ke was secretly stunned, the system was very generous this time.

However, the difficulty of the task lies in promoting planting, which is a full 10,000 hectares, equivalent to an area of ​​100 square kilometers. This is no joke.

I hope that Lime Technology will have a greater reputation in plant breeding by then, so that it can be recognized by farmers and promoted for planting.

Thinking about this, Qin Ke felt that the first group of new rapeseed, new corn, new wheat and new rice currently being cultivated should have results and patents as soon as possible and be introduced to the market.

…

After returning to school, it was already late at night, but Qin Ke couldn't sleep, so he simply projected his consciousness into the "Virtual Scientific Research Experiment Center" and began the first step of trial planting sweet potatoes.

The A-level knowledge "Cultivation Methods of New Desert Sweet Potatoes" marked twelve types of required sweet potatoes, named A female parent, B male parent, etc. It did not explain which sweet potato types correspond to reality, but there were details.

Leaves, fruit descriptions, as well as cell diagrams under a microscope, fat, protein content and other key information are included for easy comparison.

The most important thing is that it also comes with the genomic DNA characteristics of these twelve parental sweet potatoes and the final new desert sweet potato, which can be used to analyze from a biological perspective the drought tolerance and tolerance of the new sweet potato varieties after six generations of forward and reverse hybridization.

How do the activities of genes related to heat, sand burial resistance, salt-alkali resistance, and tenacity of vitality increase from generation to generation?

These theories can all be verified through experimental methods, such as using restriction enzyme cutting and electrophoresis technology to detect, and using PCR technology to amplify the enzyme digestion products, and you can clearly see the generational changes in restriction enzymes.

Another example is that there are many 3'-CCGG-5' sites on A. After hybridizing with the D parent, its cytodensity will be methylated under the catalysis of DNA methyltransferase, and the DNA sites will also be methylated.

It will be converted into 3-methylcytodensity, making the leaves smaller and thicker, thus improving its drought tolerance.

It can be said that this A-level knowledge "Cultivation Method of New Desert Sweet Potato" clearly describes the technical principles, experimental basis and experimental methods of the entire cultivation process, allowing Qin Ke to know what is happening and why.

Now that Qin Ke has 127 kinds of sweet potato seeds, the first thing he needs to do is to conduct trial planting at the same time.

Under the "time speed adjustment" function, Qin Ke only spent about fifteen minutes after planting the seeds and watering them (he had to pause for watering and fertilizing during this period) to complete the cultivation of all the seeds.

It has produced numerous fruits, and you can pull out different varieties of sweet potato fruits from the ground.

It took Qin Ke nearly another hour to complete the comparison of more than 100 kinds of sweet potatoes.

Very fortunately, the twelve varieties required in "New Desert Sweet Potato Cultivation Method" were among them. Qin Ke marked them one by one, and then started six generations of cross-breeding without stopping.

Although plant breeding work is usually carried out by scientific researchers in the laboratory, Qin Ke and Ning Qingyun will go to the field to do it themselves from time to time. Qin Ke, in particular, has already conducted experiments on tomatoes, rice, and rapeseed in this virtual scientific research experiment center.

, he is a skilled technician in the cross-breeding work of corn, wheat and other crops. This time, he does not need to rely on the help of others to cultivate the new desert sweet potato. He can complete it all by himself.

After staying up almost all night, Qin Ke finally completed six very complicated cross breedings.

He carefully dug up the soil and dug out a large bunch of sweet potatoes the size of a baby's fist. He hurriedly washed them with water and took a bite without even peeling them.

The taste is very unique. It is different from the sweet potatoes Qin Ke has eaten. It is exceptionally sweet and glutinous, making people have endless aftertaste.

Qin Ke took another sweet potato and sliced ​​it for observation. The results were exactly the same as those in "The Cultivation Method of New Desert Sweet Potatoes".

This chapter is not finished yet, please click on the next page to continue reading the exciting content! "It's done!"

Qin Ke held more than twenty sweet potatoes in his hands as if they were treasures.

He was indeed extremely excited. This is a new breed that does not exist in the world. Without systematic knowledge, it might take a hundred or two hundred years for it to be born by chance, but now it has been quietly praised by Qin Ke.

In hand!

With this new type of desert sweet potato, most deserts will have the opportunity to transform into food areas and slowly regain their fertility!

There are two ways to grow sweet potatoes. The more common one is to propagate through sweet potato vines, which has a high survival rate and is not easy to mutate. However, Qin Ke has just cultivated a new type of sweet potato and needs to produce seeds. Naturally, he will use traditional methods first.

Seed germination method for planting.

Qin Ke planted these sweet potato seeds into ten experimental plots of different soil types that had been prepared long ago. The fertility, salinity, and moisture of these ten experimental plots were all different. The last experimental plot was almost pure sand, with only a small amount of

Poor soil is mixed in.

The lighting conditions are also simulated by thermal lamps.

The final results of the trial planting were very good, almost fully meeting expectations. With special fertilizers and a small amount of root drip irrigation, the new desert sweet potatoes successfully survived and eventually bore fruit. In the tenth trial field with the worst conditions,

No exception.

And under the first experimental field with the best fertility and water conditions, it even showed amazing growth and reproduction capabilities. Only one sweet potato plant continued to branch on its own, almost covering the entire experimental field.

However, when it spread to the edge of the experimental field where the special protective agent was poured, the sweet potatoes began to wither quickly and could not cross the "boundary" even half an inch. They could only grow and reproduce in the designated area without worrying about it spreading out of control.

Moreover, Qin Ke has tried it. Once the special protective agent is sprayed and watered, the sweet potatoes in the entire test field will quickly wither. However, the protective agent itself does not have much impact on the land and is only effective on new sweet potatoes.

It is worth mentioning that in the test field with the best fertility, the final fruit produced by the new desert sweet potato has not changed much. It is still only the size of a baby's fist, but the fruiting rate is higher, that is, the yield is higher.

"Yeah!" Qin Ke couldn't help cheering. At this point, he has completely mastered the breeding method of the new desert sweet potato. The only thing that needs to be done now is how to reversely deduce several hybrid breeding plans through mathematical modeling methods, so that the laboratory's first

Three groups of scientific researchers cultivated it in reality.

Once the results were obtained, it was not difficult for Qin Ke to infer the mathematical model based on the theory, but he already felt tired.

He returned his consciousness to the real world and looked at the time. It was already past four in the morning.

Qin Ke hurriedly squinted for more than two hours, then climbed out of bed energetically. After practicing the Eastern Secret Code with Ning Qingyun, his energy had mostly recovered. At noon, Qin Ke spent about an hour,

After completing his own mathematical modeling and experimental plan, he sent it to Wei Xueming in the laboratory and asked him to arrange for a third group to conduct experiments.

Of course, Qin Ke did not directly give the best experimental plan, but first arranged for the first generation of cross-breeding, and there were several different cross-breeding plans. After that, he would gradually guide the third group to continue based on the experimental results.

Trial and error, using the most natural method to cultivate new desert sweet potatoes from generation to generation.

"Qin Xiaoke, are you in a good mood?" Ning Qingyun couldn't help but ask on the way to the classroom where they had afternoon classes.

"Yes, I feel like we are one step closer to our new goal, a new type of desert sweet potato." Qin Ke was indeed in a very happy mood. He knew very well how valuable the results he had worked out all night last night were, and it would definitely benefit mankind.

No exaggeration.

"I've seen your mathematical modeling. You established the mathematical model based on the cell structure and genetic data of more than 100 kinds of sweet potatoes and biological theory, right? Is there still some experimental data missing?" Ning

Qingjun has already seen Qin Ke's first-stage experimental plan and has a deep understanding of it.

Qin Ke smiled and said: "Yes, there is still a lack of data. When the first-stage test results come out, we will add relevant experimental data. Then we can further optimize the mathematical model and formulate the second-stage experimental plan accordingly."

Will this part of the work be left to you then?”

"Okay, it would be great if we could really cultivate the new type of desert sweet potato you mentioned. The desert can become an oasis, and it can be a crop oasis. It's exciting to think about it." Ning Qingyun's eyes sparkled, and she said to Qin

Ke had an almost blind trust, and Qin Ke said it could be cultivated, so she worked hard to cooperate with Qin Ke and move towards this goal.

"Yes, but it is estimated that it will take five to six stages of experiments to breed a new type of desert sweet potato that meets our requirements. One stage of experiment will take about three months. I estimate that the results of this new type of desert sweet potato project will be achieved.

I’m afraid it won’t be until a year and a half later.”

"I think it is a miracle that the ideal results can be produced after one and a half years. The mathematical modeling of plant cultivation is too complicated, and life is really the most unpredictable existence." Ning Qingyun sighed.

"In a sense, we have improved life, although it is only the life of plants." Qin Ke is still very interested in life sciences, but only in botany. He always has an idea for zoology and even human life sciences.

Feeling in awe, I won’t try it easily.

Probably what he will choose to contact in the future will only be in the direction of the secrets of human aging.

…

Qin Ke rested for two days and his mental and physical fitness had fully recovered. He participated in the school sports meeting as scheduled.

Qingmu University has many special sports students with extremely strong physical fitness. However, Qin Ke's original physical condition was excellent. After reaching LV5 in sports, his physical fitness and strength increased by 1.5 times, so he still successfully won the long-distance running title.

, individual event gold medals in sprinting and long jump, and also helped the class win another gold medal in the collective relay event, which caused a sensation in the whole school. Many people shouted, "I can't compare to Brother Ke in studies, and even lost so miserably in sports." Qin Ke was once again "civilized and martial arts"

The reputation of "Double Perfect" has reached its peak.

After the school sports meeting, Qin Ke began to attack the "Goldbach Conjecture" in mathematics.

This is the task requirement in the system task "Continue to take off the jewels embedded in the crown of mathematics". It is necessary to complete the proof of the Hailstone Conjecture (i.e. Kadokawa Conjecture) and the proof of Goldbach's Conjecture at the same time.

Qin Ke's other mission, "Please continue to win more mathematics awards," is also closely related to Goldbach's conjecture.

If you prove the Hailstorm Conjecture, you should be able to win the Ramanu Gold Medal early next year. However, you are not 100% sure of the Crafford Prize. Unless you solve Goldbach's conjecture, then you will be 90% certain.

Goldbach's conjecture was proposed by Goldbach in a letter to Euler in 1742, "Any integer greater than 2 can be written as the sum of three prime numbers." Later, Goldbach's conjecture was recognized by the mainstream of mathematics,

It is Euler's equivalent expression: "Every even number greater than 2 can be written as the sum of two prime numbers."
