The last human in the universe

Chapter 23
The airtightness test of the No. [-] plantation base also took two days.Zhao Changxing connected the No. [-] planting base to the No. [-] base, so that the internal air pressure reached an atmospheric pressure, and connected to the energy source to ensure that the internal temperature and humidity were both stable.

Two days later, after confirming that the sealing performance was good and fully meeting the requirements, the construction of the No. [-] planting base entered the next stage.

At the current stage, the frame is equivalent to being built, similar to the "rough". Now, what needs to be done is the "decoration" of the interior.

This work is more tedious and delicate.When building No. [-] base, Zhao Changxing spent most of his time on it.Sometimes, it takes Zhao Changxing an entire afternoon to solve the details that the two interfaces cannot be aligned, and it takes several hours or even a whole day to solve the problem that a certain plane cannot be kept level.

This time the interior "renovation" work can predictably do the same.But this time, Zhao Changxing no longer fought alone, but had six helpers.

First backfill the previously excavated earth, and re-lay evenly on the roof of the No. 100 planting base to make it a radiation-proof layer. After the huge 100-meter-long, 3.5-meter-wide, and [-]-meter-high interior In the empty room, Zhao Changxing and six helpers took off their space suits for the first time.

There are piles of building materials on the ground, which looks very messy.Zhao Changxing took a deep breath and said, "Let's begin."

His voice caused echoes in the empty and sealed No. [-] planting base.Before the lingering sound fell, a total of seven people took various tools and threw themselves into a new stage of struggle.

In the plan, excluding the areas occupied by corridors, walls, partition walls, passages, etc., the No. 9200 planting base with a total of [-] square meters has a total area of ​​about [-] square meters that can be used for planting.

As for how to allocate the 9200 square meters of planting area, Zhao Changxing had a detailed discussion with the first generation of adults who have grown up.In the end, it was unanimously determined that the first thing to ensure is the planting area of ​​silage corn.

Silage corn is an excellent feed. Its planting area is directly related to the growth of livestock, how much meat people can eat in the future, and the health of all people.

At this stage, the amount of feed is seriously insufficient, so that the animal husbandry and aquaculture workshops in Base No. 30 can only operate at [-]% power, and the level of meat output has also been maintained at a low level for a long time, which is really not enough.

Think about it, a hot pot party can consume at least 30 kilograms of meat in one meal. How can such a small amount of livestock be able to eat it?

What's more, the 60 children of the third generation are also growing up slowly, and the demand for meat is increasing day by day, which must be considered in advance.

In the end, among the 9200 square meters, people unanimously agreed to set aside 3000 square meters for planting silage corn.The growth cycle of silage corn is shorter than that of normal corn. It can be planted for 6 rounds a year, and one round of planting can produce about 10 tons of feed, which is 60 tons a year. In addition to the previous ones, it is enough to support animal husbandry and aquatic products. The breeding workshop is running at 100% power.

In addition to silage corn, another more important category is the staple food.The main staples are rice and wheat - potatoes are not considered.

There is rice and wheat, and no one wants to eat potatoes.The same goes for sweet potatoes.Potatoes and sweet potatoes are mainly used to produce starch for industrial use or as feed, or to make some wide vermicelli noodles. If they are used directly as staple food, Zhao Changxing thinks that it is not so miserable.

The output of Human Base No. 50, according to Zhao Changxing's previous calculation, is about enough to consume 41 adults and dozens of children.And now, the second generation of children is about to become adults—in fact, their appetite is no worse than that of adults. In this way, adults can be counted as 60 people.With the addition of [-] children, although the output of the No. [-] base can still be supported, there is very little food that can be saved and put into the warehouse.Some categories of food are even beyond our means.Fortunately, there are previous reserves in the storage area, so it can be temporarily supported.

It's just that seeing that some categories are only exported but not imported, and the number of categories that can be saved is getting smaller and smaller, Zhao Changxing always feels as painful as a knife cutting his own flesh.

Rice and wheat each obtained 2000 square meters of planting area.These two kinds of crops can adopt the double-layer planting method to maximize the use of space, that is, the planting area of ​​each is 4000 square meters.

There are 4 rounds a year, one round of planting, the wheat can produce about 3.5 tons, and 4 rounds is 14 tons.A round of rice can produce about 5 tons, which is 20 tons a year.

With this year's 34 tons - minus the loss of about 4 tons or the impact of accidents, diseases, etc., there are also 30 tons.Wheat is ground into flour, and rice is turned into rice, each with a loss of about 3%. The total amount of flour and rice harvested in the end is 21 tons.

Assuming that an adult consumes 0.5 kg of staple food per day with sufficient non-staple food, the annual output of 21 tons is enough to feed 120 adults.What's more, the 9% loss, that is, bran, rice bran, etc. - about [-] tons in weight, is not thrown away directly. They are also good feed, and they will turn into meat when fed to livestock. become part of the human diet.

In general, the planting of rice and wheat in Plantation No. 30 will greatly reduce the pressure of population growth on food demand.Based on the current population growth rate, at least for [-] years, Zhao Changxing no longer has to worry about food shortages.

The planting of the three crops of silage corn, rice, and wheat occupies an area of ​​7000 square meters in the No. 2200 planting base.There is an area of ​​[-] square meters available for use.

Vegetables will definitely not be considered. The vegetables produced in the vegetable planting area in the No. [-] base are enough to eat.After all, this thing has a high output, occupies a small area, and grows fast.At the current stage, the uneaten vegetables are directly used as feed for livestock.

Among these areas, an area of ​​200 square meters is divided, and it is planned to plant various fruit trees, such as apples, pears, grapes, bananas, etc., to enrich people's diet.Another 1000 square meters are used to plant soybeans, with an annual output of about 4 tons.

The remaining 1000 square meters were used to plant some miscellaneous things, such as cotton, peanuts, rapeseed, sesame, oil sunflower, sugar beets, sugar cane and the like.

Some people also suggested that the cotton planting area should be expanded for the development of light industry, especially the cotton spinning industry.After all, the Tinder spacecraft did not carry too many clothes, quilts and other materials, and these things had to be produced by itself.And at this stage, even if the newborn children are asked to pick up the old clothes worn by their older brothers and sisters to wear, the number of clothes is almost not enough.

Adults generally only have two sets of clothes, both of which are worn out.People are very much looking forward to have a few new clothes to wear.

But this request was brutally rejected by Zhao Changxing.He believes that under the premise that there are sufficient temperature control facilities in all human activity areas, there is no need for clothing to keep warm.Then only the aesthetics and body covering function are left.For these two functions, old clothes can also be used. There is really no need to waste precious planting area at this stage.

Even if such a little cotton is grown at this moment, it is not used to make clothes, but to be used for industrial purposes.

This makes the first-generation youth, the second-generation teenagers, and even the third-generation children unhappy.There is no way, Zhao Changxing has to guarantee that in the future, as soon as conditions permit, the No. [-] planting base will be built immediately, and large quantities of cotton will be planted to develop light industry, so that people can barely accept it.

The internal construction of the No. [-] planting base has been vigorously launched.With an area of ​​up to [-] square meters, if Zhao Changxing were to do it by himself, it would be impossible to complete it without a few years.But with the addition of helpers, this time was shortened to a fraction of the original time.

In just one year, the internal construction has begun to take shape.At this time, the second group of humans has also grown up, and it's time to start working.

Zhao Changxing and the first generation of humans welcomed them to Base No. 20 and allocated their own rooms.So far, all [-] rooms in Base No. [-] have been occupied, and there is even one more person who has no place to live.

Many people offered to let Zhao Changxing live in a house in the leisure and entertainment area, or find a place in the industrial area, but Zhao Changxing firmly refused.He believes that, as the oldest of all men and the de facto "leader" of all humanity at this moment, he has an obligation to lead by example.So he chose to live in the leisure and entertainment area by himself, allowing everyone from the first and second generations to live in the room.

With the addition of the second batch of 30 adult humans, the construction of the No. [-] planting base was accelerated again, and all construction tasks were finally completed almost half a year ahead of schedule.

At this moment, each area has been completely divided, and various internal equipment, such as water supply, power supply, temperature control, humidity control, automatic planting, maintenance, harvesting modules, etc., have all been installed.The various substances needed to prepare the nutrient solution have also been collected, and the substrate used to fix the root system of the crops has also been spread on the top of the petri dish.

Followed by a total of 40 people, Zhao Changxing came to the No. [-] planting base full of joy.Standing on the corridor, Zhao Changxing solemnly pressed the start button.So the next moment, the temperature control and humidity control equipment started to operate, adjusting the different planting areas to different climates.The automatic planting equipment started to operate, sowing the seeds of many crops into the substrate.

"Soon, we will be able to harvest a lot of food..."

Zhao Changxing thought silently in his heart.
