Thanks to the fact that Itakura Town was a high-tech zone before the end of the world, and a large number of scientific and technological manufacturing equipment was left here.

Although Itakura Town does not have the moore memory production equipment of 50 years ago, after Ding Liang is familiar with the manufacturing principles and drawings, there is no problem in assembling and manufacturing parts removed from other equipment.

The farming community handed over 100 catties of corn to the Canaan family before they had the right to wander around the factory near Itakura Town and search for materials.

The Canaan family deserves to start the price of business, and found that the broken copper and iron in the original science and technology industrial park can be valuable, so they sat on the ground and started the price, and directly collected 100 catties of corn from the planting community.

This was unanimously protested by the residents of the community, including Ding Liang, and no one thought that a few pieces of broken copper and iron could be worth a hundred catties of corn! It's corn, not corn on the cob! Enough food for ten people for a month!

Luo Miao is well aware of the importance of the Blue Star technology industry to Chen Nuo, the food can be reproduced if there is no food, or Chen Nuo will bring it back directly from the earth, but the technology is gone, and the Blue Star World will lose its attraction to Chen Nuo, and Chen Nuo will not come back.

Luo Miao paid off a hundred catties of corn to the Canaan family against public opinion, Chen Nuo was not there, Luo Miao was the head of the planting community, and all the warriors and slaves in the community obeyed Luo Miao's orders, so no one dared to say more.

The slaves also suffered a lot, and after paying the price of one death, they forcibly brought all kinds of equipment parts back to the farming community.

Ding Liang spent a week looking for a few helpers, and the equipment was assembled day and night and tested successfully.

Fifty years ago, the Blue Star World was produced again with a mole of graphene the size of a fingernail.

Ding Liangyou disassembled the old projection computer and installed the memory into it, perfect!

Chen Nuo tested Ding Liang's work, trying to convert the data of graphene mole memory into data of the earth, such as memory size and frequency.

Compared with the earth's memory particle silicon wafer integrated circuit, Bluestar uses graphene stacked particles, so there can be no nanometers to measure.

The size of the memory can be converted, and the memory used by Ding Liang for the experiment is about equal to 128G memory, which belongs to the smallest unit of measurement of graphene molar memory. And the frequency is up to 8000MHz or more! Beat up the computing speed of any memory module on the planet!

Chen Nuo just hopes to be backward compatible, after all, the motherboards of computers and mobile phones on the planet have not yet supported such a high frequency of memory devices.

Ding Liang combined his own practice and used a computer to write tens of thousands of words of graphene mole memory manufacturing methods for Chen Nuo, accompanied by drawings and a video version of his installation equipment.

Ding Liang's information is much more detailed and operational than the encyclopedia on the computer.

Chen Nuo can definitely hand over this title book to his scientific research team on the earth, and the scientific research team can make graphene mole memory without caring about the principle.

The biggest highlight of graphene moore memory is that it is cheap in addition to the large memory size, small size, and super fast read and write speed.

The device can make carbon particles into graphene, and the graphene can be superimposed, side-by-side packaged, etc., to become the basic unit of memory.

Chen Nuo was very happy after getting the experimental results, and immediately announced that Ding Liang was promoted to the head of the community science and technology department, and he could have three ham sausages for dinner a week, and this treatment lasted for half a year!

Ding Liang was ecstatic, grateful to Dade!

Trade ancient technology for food! Ding Liang found his value in the community.

At the same time, Chen Nuo threw the drawings of the earth's fertilizer equipment and production drawings to Ding Liang and asked him to find someone to figure it out.

The production process of chemical fertilizer is expressed by chemical formula, which is no different from Bluestar, and some of the words on the equipment drawings were also annotated by Chen Nuo for three days to be annotated into Bluestar characters, which is easy for Bluestar people to understand.

Ding Liang is not omnipotent, he is very unfamiliar with chemical fertilizers, he can only say: "I'll look and see who understands chemistry." ”

However, Ding Liang added: "Fertilizer? Blue Star seems to have been using this thing to grow plants a hundred years ago, but later it was replaced by microbial trophic bacteria. ”

Chen Nuo has heard that compared to ancient chemical fertilizers, the agriculture of the Blue Star World has used microbial nutrients.

Agriculture in the Blue Star World is divided into two types, one is traditional agriculture and the other is modern agriculture.

Traditional agriculture is where plants are planted on the land.

In modern agriculture, plants are planted in a culture medium, and the farm is no longer a piece of land, but an agricultural building, and the equipment of the building provides the plants with the light and temperature they need. With the scarcity of land in Blue Star, the concept of protecting nature and protecting the original state of the land has been strengthened, and more and more farms are choosing modern agricultural methods, and only more backward places such as growing communities still have traditional farms.

However, no matter what kind of agriculture it is, the role of microbial trophic bacteria is irreplaceable!

Microbial trophic bacteria are bacteria developed by generations of agriculturists in Bluestar and have a symbiotic relationship with plants, which coexist in plants, absorb materials containing elements needed by plants in culture medium, air, or soil, such as nitrogen, carbon dioxide, potassium, phosphorus and other substances and elements, and then synthesize nitrogen, carbon, potassium, phosphorus and other elements into compounds that plants can absorb and digest the most through the chemical reaction inside the bacteria. These compounds promote plant growth and increase production, and vegetative bacteria secrete chemicals that are beneficial to humans but resistant to plant diseases. The biggest advantage of trophic bacteria is that they do not pollute the soil and air, and do not destroy the ecological balance.

According to the data, before the end of the world, taking traditional agriculture as an example, the rice yield reached 10,000 catties per mu. Modern agriculture has reached an exaggerated yield of 60 catties per cubic meter.

However, with the advent of the end times, the trophic bacteria cultivated by humans are not as lucky as Oleoleum dermogenesis, and there are no living vegetative bacteria in this world.

The reason why Chen Nuo wants to let the farming community produce their own fertilizer is to really rebuild the agriculture of the farming community! If the community wants to grow, it can't rely on Chen Nuo to carry fertilizer and food every time.

If the soil fertility is insufficient, chemical fertilizer will be used to make up, and at this time, there will be no problem of land compaction.

Chen Nuo said: "Yes! Fertilizer, we need a guy who is good at chemistry! ”

Ding Liang said again and again: "I'll do it right away." ”

Luo Miao also came back, and when she saw Chen Nuo, she was overjoyed, and she ran up to be a big bear hug!

"I've got you a good thing and a piece of news, you want to know that first?" Luo Miao sniffed the smell of Chen Nuo's body fiercely, this is the smell of shower gel that only exists on earth.

"Something good, huh?"

"Loyalty Chip! I don't know which guy in the community improved the loyalty tester, and the loyalty chip can be implanted in the human body, so that you can better grasp the loyalty of your slaves and soldiers! ”
