Comprehensive cooling is an expectation that has been speculated since the bottom of the floating island was discovered to be separated from the steam sea.
The temperature has indeed been slowly decreasing in the past few years. The nighttime temperature has dropped from 22 to 24 degrees to 16 to 19 degrees. The change is not particularly obvious, less than two degrees a year.
And just last night, a sudden cold wind blew from the northwest, lowering the temperature by ten degrees in the blink of an eye.
Even though it wasn't freezing yet and the temperature was back above fifteen degrees by daybreak, it was a very bad sign.
Wang Qi was pulled into a meeting by Manager Levin early in the morning. It wasn't even for him to make the decision, but because there were too many advance plans triggered by the cold wind. She couldn't manage so many meetings by herself, and her deputies didn't have enough authority to do it. wasting time.
Wang Qi was in charge of the Ministry of Foreign Affairs, Agriculture and Industry, while Levin was in charge of administration and economy.
"All work is progressing according to His Majesty's plan, but it is still difficult to roll out at this time."
"Have you brought all the information on artificially growing edible fungi and tuber shrubs?"
"Your Majesty, please take a look!"
The Ministry of Agriculture official pulled out three folders, handed them to his deputy and quickly delivered them to Wang Qi.
Wang Qi spent ten minutes going through it roughly, and the progress was indeed not satisfactory.
The most troublesome among them are edible fungi.
This thing limits the approximate culture medium materials, but in actual operation, just purifying the strains is a very time-consuming task.
The so-called strain purification means to exclude non-target strains in an artificially controlled environment. It sounds easy to say, but based on the fact that a normal person is exposed to 7,000 mold spores every day just by breathing, it is almost impossible to isolate a 100% pure single strain of bacteria.
If there are not enough pure strains, the direct result is that the edible fungi growing on the culture medium will be mixed with a certain proportion of miscellaneous bacteria. In order to avoid the chain punishment caused by food poisoning, these miscellaneous bacteria need to be removed manually, which increases the work process. Not to mention, the existence of miscellaneous bacteria itself robs the nutrients of the target bacteria.
According to the document, in the latest batch of finished products, the output of the target bacteria accounted for 98.4% of the total weight of the fruiting bodies, and the remaining 1.6% were detected with three types of fungi, one of which was confirmed to be a toxin and one that can cause It is poisonous but the infection rate is very low. The principle of its toxicity is temporarily unknown. The remaining one cannot enter the vegetable market because its sporangia are extremely hard and taste like sand.
The entire batch mixed with toadstools like this cannot be used for bacterial strain purification.
There are also corresponding methods. A level 3 biological protection laboratory should be established, and personnel do not need to be completely isolated from the air. They must be disinfected and sprayed when entering and exiting, and indoor and outdoor air are not allowed to circulate directly.
The laboratory environment is more controllable and can be operated in separate laboratories. It is expected to increase the purity of bacterial strains to more than 99.8% in a short period of time, accounting for two thousandths, even if no bacteria are detected during the process of leaving the shed. , as long as people don’t chew on the fruit body, there won’t be any big problems.
But having a corresponding method does not mean it is feasible.
Affected by the overall size of the kingdom, the agricultural population is limited and there are very few talents. Some people who graduate from the Agricultural College of Phoenix University will go to the chemical industry. The brainpower that a single agricultural enterprise can invest is extremely limited, and the third-level protection laboratory is not a single one. Affordable for agribusiness.
After this situation with edible fungi emerged, the Ministry of Agriculture organized multi-party negotiations and finally decided to build a biological protection laboratory building at Higashi Sando University.
It was not placed in Phoenix City because the agricultural conditions in Phoenix City are too poor. In half a year, the entire Agricultural College will move to Higashi Sando University together with the Astronomy College.
There is no big problem with the plan itself. It has only been two years since the introduction of edible fungi. It can only be said that the plan cannot keep up with the changes.
"As for the edible fungi, we will proceed as planned." Wang Qi said it was settled, but there was just a cold wind blowing, and it did not drop directly below freezing point.
The point is that there are two other food-related items, peanuts and tuber shrubs.
Both are food sources prepared for foreign countries, but they are different and difficult to replace each other.
Before the peanut project started, the cooling trend had not been realized. Even if it inherited a certain frost resistance from the sacred tree, it did not have the production capacity after being completely covered by snow. So it should be planted in a greenhouse after it cools down completely.
Plastic greenhouses have thermal insulation properties, but they are not invincible. As the temperature difference between the inside and outside of the greenhouse increases, the heat exchange rate will become higher and higher based on the same thermal conductivity. This means that if it is minus 50 degrees outside the shed, it will be difficult to maintain the temperature above 10 degrees above zero even if a fire is directly lit inside the shed.
Sacred tree peanuts still have a good fruiting rate at 8 degrees Celsius, which determines that they are more cold-resistant than ordinary plants under the same heat preservation method. In extreme environments, they may become the only source of vegetable oil.
The Ministry of Agriculture still focuses on schools in this area. It determines what kind of insulation methods and water and fertilizer ratios are needed under various temperature differences between inside and outside the greenhouse.
Glass greenhouses are not considered, because double-layer glass greenhouses can maintain a temperature difference of 80 degrees or even greater between the inside and outside at a lower cost by utilizing the air layer. However, its construction cost is difficult to accept overseas, and the existing transportation conditions are not good. There is no way to transport so much glass.
Mainly plastic sheet greenhouses.
Unlike glass, plastic cloth cannot be double-layered. This depends on the characteristics of the plastic itself. It is prone to electrostatic adsorption of dust, so the plastic cloth will become frosted in a few days. The light transmittance after double-layering too low. If it has to be double-layered, it will require a lot of management labor. It is better to move it directly indoors and use magic lights to fill in the light for planting.
A single layer of plastic sheeting can only maintain a temperature difference of 15 to 18 degrees between inside and outside. If it exceeds this number, it must be covered at night to keep it warm, or to provide heat.
The existence of natural magic makes it easier to supplement heat and light, but magic equipment also requires manufacturing power, and the process is also limited by the number of magic personnel. When the threat of demons cannot be eliminated, the production capacity used to produce these things is really large. limited.
Moreover, in overseas situations, even if it is built, others may not buy it.
At this stage of research on peanuts and tuber shrubs, peanuts may not be able to adapt to ultra-low temperatures, but tuber seeds can be sown in batches in the field.
On the contrary, there are more diplomatic and industrial jobs, and it is still a matter of plastic sheet greenhouses.
This thing was pushed a few times before, but no one outside responded. Taking advantage of the cold wind, more people should be alert.
It certainly cannot be ruled out that there will still be a group of people who won’t shed tears when they see the coffin, but if it can be pushed forward earlier, it can also reduce the storage pressure and subsequent transportation pressure of the gold chemical industry.
Wang Qi also decided on the specific method during the meeting, buying plastic sheets and giving away peanuts.
Although there are probably thousands of tons of peanuts in the wild fields in the south, these peanuts are eaten by civilians just like tuber shrubs. When it comes to buying plastic sheeting to build greenhouses, many naked civilians abroad cannot afford it. They can only buy plastic sheets from large households, and the peanuts they receive count as seeds.
The Ministry of Foreign Affairs and the Ministry of Industry have another job, which is to push cement, or give it away for free.
Affected by the long-term warm environment, a large number of civilians live in straw huts all the way south to the border, within a range of 600 to 800 kilometers.
This thing can effectively avoid the heat when it's hot, and it's really cool when it's cold.
Cement cannot be transported by air and can only be produced locally. It is difficult for the poor to use it when it comes out. But as long as the house can be replaced with cement, there will always be more living resources and some wood consumption can be saved.
Of course, even for wood, it is difficult for poor people living in thatched huts to come up with money, but if someone lends a saw, as the temperature drops, everyone has to think of a way to survive.
In short, the overall policy is to rather not make money in the next one or two years, but to preserve the population first!
If the population is preserved, there will be a market and future productivity.
