Chapter 1950: New Technology with Good Quality and Low Price

For those who have developed good work and study habits, as long as they are on the right track, the daily routine that follows the process is a cumulative process for them and there is no difficulty.

Therefore, Zhou Zhi’s main job now is to deal with the challenges brought by the new business. To put it bluntly, it is to help Mai Xiaomiao establish a work management model.

Mai Xiaomiao is a person who is used to working alone. He is a "brain knight". His strength is conquering unknown areas in the ocean of mathematical knowledge, but he is not good at managing a team of subordinates in the real world.

Moreover, given her appearance and personality, she is not suitable for a management position.

However, in Zhou Zhi's words, Mai Xiaomiao's charm is enough to conquer people who are good at engineering management, such as himself and Hu Tianyu. In the workplace ethics of Clover, the charm of engineering managers is actually smaller than that of technical experts, and the charm of technical experts is smaller than that of theoretical experts.

Zhou Zhi does not want to correct the phenomenon of "not treating the CEO as a cadre". On the contrary, he believes that this should be a quality that a company with technology as its main business should possess.

Therefore, even though Zhou Zhi was helping Mai Xiaomiao, he enjoyed it.

As a result, this pair of people achieved quite impressive results. Originally, Mai Mingdong was quite dissatisfied with his granddaughter following Zhou Zhi to the remote countryside, but now that the results were there, he could not find any reason to object and could not say anything.

"You said you've been hanging out with a little girl lately?" Even Liu Liangzhen, who always only talked about work, started gossiping: "She's already a leader in her field at such a young age. What a strong combination. When will you bring her to grandma to see?"

Zhou Zhi is struggling with alcohol lamps, test tubes, culture media, and potato germs. This is a compulsory course in biotechnology. First, one must obtain a large number of samples with the same genes and traits, which are academically called "strains". Only after having strains can one apply different stimuli to the samples and study the effects of these different stimulation conditions on individuals with the same genes, thereby screening out useful conditions.

For animals, the breeding of this kind of strain is a very difficult process, because in people's general concept, through continuous inbreeding, "purified genes" can be obtained, and the genes of the offspring will tend to be unified and stable.

However, this is a double-edged sword, because the genetic defects of the individuals bred in this way will be equally solidified or even amplified. Eventually, these individuals will have various genetic problems and lose the ability to "carry on the family line."

It was not until 1913 that American researchers studying cancer successfully bred an animal strain that was suitable for inbreeding and had strong reproductive ability. This strain of experimental animals is still widely used today. This is the BALB/c mouse, commonly known as the "little white mouse."

Since the invention of mice, many biomedical technologies have achieved rapid progress.

For plant research, this approach also has the same value. The only advantage is that the genes of different plants, especially those in closed areas, are very similar and very stable. After screening, supplemented by modern scientific and technological cultivation methods, a large number of experimental samples of the same strain can be quickly replicated for use in scientific research experiments.

What Zhouzhi is doing now is the basic work of agricultural science and technology, expanding and propagating varieties. The nutrients are dissolved in water by heating, gelatin is added, and the melted gelatin is injected into the culture dish. The embryos are taken from the sterilized potatoes, and the embryos are inserted into the gelatin with tweezers sterilized by an alcohol lamp, and the lid of the culture dish is closed to allow the embryos to germinate safely under sterile and undisturbed conditions, and then become plants.

Such plants are extremely fragile, just like strains of mice, so they need a process of strengthening. Generally speaking, the seedlings are cultivated stage by stage, and the cultivation conditions become more extensive stage by stage, so that the fragile seedlings can gradually become strong plants, and eventually they can bloom and bear fruit, and then enter the next round of expanded reproduction.

Therefore, some necessary agricultural technologies must be introduced into this process, such as mulch technology and greenhouse technology.

Zhou Zhi once gave Liu Liangzhen an idea, which was to change the color of the ground film to black. This has many advantages. First, black absorbs heat, which can make the ground temperature higher than ordinary ground film; secondly, it isolates light. Except for the seedlings planted at the openings, the rest of the weeds in the field cannot survive due to lack of light, thus achieving the purpose of "harmless weed control."

Liu Liangzhen thought this was a good idea, and together with Zhou Zhi, she took the idea to the manufacturer of mulch film in the autonomous prefecture. The manufacturer said that this task was too simple for them, and it would only require adding black emulsifier to the plastic.

Then a factory technician made a suggestion. Since the purpose of using black ground film is to increase the ground temperature, if your funds allow, we can actually make a fully reflective covering ground film for fun.

Zhou Zhi was dumbfounded. Although you guys have undertaken some of the production of aerospace materials, you can't just do it without saying anything, right? Total reflection, no energy loss, it doesn't sound like it conforms to the laws of physics.

The technician laughed and said that Mr. Zhou might be a liberal arts student. The total reflection phenomenon is an optical phenomenon, and of course it also has an effect on the radiation propagation of heat. The production method is not as complicated as Mr. Zhou imagined.

The so-called total reflection actually refers to the phenomenon that when light enters a medium with a higher refractive index from a medium with a lower refractive index, if the incident angle is greater than a certain critical angle, the refracted light will disappear, and all the incident light will be reflected without entering the medium with a lower refractive index.

Zhou Zhi suddenly slapped his forehead. Optical fiber in signal transmission technology uses this principle for lossless transmission. How could he forget it at this moment? !

There is no need for the technician to explain in detail. The so-called fully reflective ground film does not mean that it will reflect all the geothermal heat back. Instead, it is manufactured using the principle of total reflection. An inner layer is sprayed on the ground film. The refractive index of this inner layer is higher than that of the outer layer. The heat radiated from the ground exists in all directions. When they encounter such a ground film, all geothermal heat with an incident angle greater than the critical angle will be reflected back, which will slow down the loss of geothermal heat to a considerable extent.

It is equivalent to the black outer layer opening the source and the high refractive index inner layer reducing the flow, thus improving the heat preservation efficiency.

From a certain visual angle, the inner layer of such a ground film will have a metallic reflection effect, but in fact there is no metal at all. It is purely a physical phenomenon created by the superposition of different transparent materials.

The cost is not as high as Zhou Zhi imagined. At least for the Academy of Agricultural Sciences, it is good value for money.
