It is still unknown how many years of overseas food influence support peanuts can provide.

While Wang Qi was paying attention to the changes in the average temperature and air pressure, he was also staring at the relevant low-temperature experiment results.

In order to ensure that sufficiently reliable conclusions can be obtained, some experiments were handed over to the Department of Agricultural Sciences of Phoenix University.

Compared with Professor Olan's team at the School of Magic, the Department of Agricultural Sciences still has many shortcomings. Without the corresponding equipment, they cannot create multiple constant temperature zones with different temperatures in a single greenhouse.

The advantage lies in the large number of people, who can take care of hundreds of small greenhouses and thousands of laboratory plants at the same time. Olan's team is an interest group, and given so many resources, they don't have enough manpower to record information.

The progress of the laboratory is the same as that of the wild experiment, which is roughly two and a half growth cycles, and a total of more than 20 constant temperature or combination temperature conditions have been tried.

According to the minimum standard of developing 30 peanut seeds from one peanut seed, the minimum constant temperature for the laboratory strain to maintain yield is 14 degrees, and the growth cycle is extended to 122 days.

14 degrees is considered a relatively low temperature. Many staple food crops are prone to yield reductions such as empty fruits at this average temperature. Designed crops such as sacred tree peanuts still have certain advantages. However, compared with the expected cooling, 14 degrees is still

If it is too high, it will be difficult for the wild environment to reach this level after cooling down.

The exploration expedition team's prediction of the future climate is that in three to four years, the surrounding areas, which have never seen snow before, will experience more frequent snowfalls.

Whether the snow falls in seasons or occurs randomly throughout the year, there is no way to draw a conclusion yet. Even if we consult forecasters, they lack relevant professional knowledge and they cannot make such detailed predictions.

As long as it snows, no matter how warm the rocks underneath the floating island are, the surface temperature will not be able to withstand it.

Therefore, the Department of Agricultural Sciences focuses on the environmental freezing point expectations for peanut rewilding needs.

In the two experiments of constant freezing temperature and freezing point at night and above zero during the day, the peanut harvest was not completely eliminated. The former had a growth cycle of 135 days, with a seed-to-fruit ratio of 1:10, and the latter had a 133-day growth cycle, with a seed-to-fruit ratio of 1:13.

The freezing point of serious herbs has not developed. This performance should be considered quite good. As a result, peanuts will gain the status of the main food for a few more years.

The extra years mainly come from the difference between the underground temperature and the surface temperature. Before the whole floating island stone drops to the freezing point, the underground temperature will be higher than the surface for a long time, so after snowfall, the surface temperature will hover around the freezing point, which will not

Keep going down.

There is also a set of results from harsh environment experiments worthy of attention.

Temperature controlled room at minus 30 degrees Celsius.

Ultra-low temperature and constant temperature require that plants at least have the hope of contacting liquid water. They spent a lot of time on the design, and also asked the Magic Academy for help, and finally achieved the freezing point 30 centimeters below the soil layer.

If the actual ambient temperature drops to this level and remains for more than half a year, the freezing point will most likely reach two meters underground. However, such an experimental environment is completely meaningless for peanuts, and its root system cannot penetrate that deep.

In the harsh experiment, peanuts had two new situations.

One is the seed method for germination, and the other is to transplant the germinated seedlings to the laboratory. The peanuts will restore the cold resistance of the sacred tree and still maintain a seed-to-fruit ratio of 1:8, and the cycle is not particularly long.

The period until the plant shrinks is within 150 days.

In other words, if Wang Qi gives the peanut another iteration and makes its root system deeper, it will be able to grow in the harsh cold environment.

However, at that temperature, there are no active insect pollinations at all, and artificial intervention is needed. Since artificial intervention is already done, why not focus on planting, at least the temperature environment will be much better.

Here comes the problem.

Wang Qi’s purpose in making peanuts is to ensure that the minimum overseas working income level is not too low through a food that is centrally controlled under one law, thereby curbing the tendency of industries to relocate overseas.

Once peanuts are centralized and controlled, most of the workers' food will again be in the hands of merchants, food prices will rise again, and everyone will return to the state of working hard all day to barely make it to Hukou.

It is not ruled out that businessmen in some areas will have some conscience, but until glass greenhouses and plastic sheet greenhouses are popularized, it is difficult for the overall trend to change.

To maintain the ultra-low temperature wild ability of peanuts, it is necessary to improve the length of the root system, eliminate the need for direct self-replication in the pollination process, and perhaps add a wax layer above the surface to assist in water retention and heat preservation, and the leaf shape must also be changed to adapt to the severe cold.

...After such a change, it seems that it is better to create a new Ice Age crop. After all, when the topic of peanuts was chosen, the bottom of the floating island had not yet separated from the steam sea, so it was obviously not suitable for the version change.

Wang Qi didn't hesitate too much. After a few years of using peanuts, he could get some new cold-resistant wild plants.

A small-leaf, deep-rooted tuber plant.

Wang Qi, who had already figured out how to get rid of the risk of contaminating the core body, was familiar with the process this time, and it took him a few days to produce the first generation in the palace.

On the deep-rooted sweet potato, Wang Qi retains more of the divine tree ability. The plants no longer use herbs, but shrubs. If they are not made into big trees, they can avoid being controlled by local snakes. In addition, the entire plant needs to be dug out for collection, which will

System roots extend around the main root, expanding and growing into a tuber similar to a sweet potato.

Without wasting time, I directly copied a bunch of them using the sacred tree seed version and gave them to the Department of Agriculture.

Supported by feedback from early peanut rewilding and experimental data from the Department of Agricultural Sciences, small shrubs will not be considered for overseas field experiments for the time being. After all, perennial shrubs have higher morphological advantages than most herbs. The only thing to worry about is being eaten by wild herbivores.

Gnawing bald.

There are not many ways to target herbivores.

Poisoning the leaves is contrary to the original intention, because the survivability of small shrubs in high-density jungles is limited, and these dead animals can be seen far away, and there is a high probability that they will be picked up and eaten by people.

The long thorns cannot be effective on all animals, and Wang Qi does not pursue perfection. Planting the sacred tree directly has the disadvantage of controlling the food source. A little bit eaten by animals counts as a contribution to meat production, and a lower yield is harmful.

After making arrangements for the extremely cold wild food, I looked back at the condition of the motor.

Electric motors are an industry that started very early. Unfortunately, it has been affected by the supply of natural paint and has been unable to expand its scale. It is limited by the development of various lubricating products in the petroleum industry, and the quality is not very good. It was only after the development of derivative paints based on polyolefin materials.

Find an opportunity and push it.

It had been some time since the previous arrangement of the motor branch factory, and Wang Qi mainly read the reports of Xincheng Heavy Industry.

Xincheng Heavy Industries is not only a major buyer of high-end motors, but also a designated supplier of automation equipment for the motor industry. They do not produce motors themselves, so they will look at the issue more objectively.

Heavy industry only focuses on the iteration of precision machining technology, and production equipment is a sideline. Regarding the direction of the motor, their focus is on vibration and heat... This is also the area where the technical strength of the motor is concentrated, and the winding is a simple arithmetic problem, and the casing has technical components.

But not much, just a little bit.

In the six months since the supply of motors entered a stable period, the heavy industry has burned out more than 600 motors.

After extensive review and analysis, it was found that the existing enameled packages were still not good enough and had low thermal conductivity, which limited the increase in motor power.

As a control group, a natural mineral paint is also an early material paint. When other conditions are exactly the same, the average burning power of the paint package using mineral paint is more than 20% higher than that of polyethylene paint.

This type of destructive testing should originally be the job of the motor factory, but the current focus there is on the debugging of new equipment and the adaptation of related production processes. The finished products are sold according to the rated power with a 30% reduction in the burnout power measured by the prototype. There is no professional

The team is doing too complex testing work.

The problems faced by heavy industry are more complex. Machine tool processing requires the torque of the motor system to jump back and forth. There will be various factors that cause the motor power to fluctuate significantly in a short period of time, so it is more suitable to help with some testing work. Related

A copy of the records will also be given to the motor factory to help them make subsequent improvements. They themselves will use the results to decide what power motors will ultimately be used for various machine tools.
