The sealing test of the No. 2 planting base also took two days. Zhao Changxing connected the No. 2 planting base to the No. 1 base, brought the internal air pressure to one atmosphere, and connected the energy source to ensure its internal temperature.
and humidity remain stable.
After two days, after confirming that the sealing performance was good and could fully meet the requirements, the construction of the No. 2 planting base entered the next stage.
At the current stage, the framework has been built, similar to a "rough". Now, what needs to be done is the "decoration" of the interior.
This work is more tedious and precise. When he first built the No. 1 base, Zhao Changxing spent most of his time on this. Sometimes, the details of the two interfaces not being aligned can cost Zhao Changxing a whole afternoon.
If a plane cannot be kept level, it will take several hours or even a whole day to solve it.
It is foreseeable that the internal "decoration" work will be the same this time. But this time, Zhao Changxing no longer works alone, but has six helpers.
First, the previously excavated earth was backfilled and evenly laid on the roof of the No. 2 planting base to make it act as a radiation protection layer. After that, a huge building with a length of 100 meters, a width of 100 meters, and a clear internal height of 3.5 meters was built.
In the empty room, Zhao Changxing and six helpers took off their spacesuits for the first time.
There were piles of building materials on the ground, which looked very messy. Zhao Changxing took a deep breath and said, "Let's get started."
His voice caused waves of echoes in the empty and sealed No. 2 Planting Base. Before the sound lingered, a total of seven people took various tools and plunged into a new stage of struggle.
In the planning, excluding the area occupied by corridors, walls, partitions, passages, etc., the total area of the No. 2 planting base of 10,000 square meters that can be used for planting is about 9,200 square meters.
As for how to allocate the 9,200 square meters of planting area, Zhao Changxing had a detailed discussion with the adult first-generation humans. In the end, everyone unanimously determined that the first thing that needed to be ensured was the planting area of green storage 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 everyone.
At this stage, the amount of feed is seriously insufficient, resulting in the livestock and aquaculture workshop of Base No. 1 being able to operate at only 30% power, and the level of meat output has also been maintained at a low level for a long time, which is really not enough to eat.
Think about it, a hot pot party can consume at least 30 kilograms of meat in one meal. How can the animals raised now eat it?
What's more, the 60 children in the third generation are also growing up, and their demand for meat is increasing day by day. This must be taken into consideration in advance.
In the end, among the 9,200 square meters, people unanimously agreed to set aside 3,000 square meters for planting green storage corn. The growth cycle of green storage corn is shorter than that of normal corn. It can be planted six times a year, and one planting cycle can
The output of feed is about 10 tons, which is 60 tons per year. Including some that were already there, it is enough to support the livestock and aquaculture workshop to operate at 100% power.
In addition to green storage corn, another more important category is staple food. Staple food is mainly divided into rice and wheat - potatoes are not considered.
There are rice and wheat, but no one wants to eat potatoes. The same is true for sweet potatoes. Potatoes and sweet potatoes are mainly used to make starch, which can be used for industrial purposes or as feed, or to make some wide vermicelli noodles and the like, and take them directly.
If it were the staple food, Zhao Changxing thought to himself that it wouldn't be that miserable.
Zhao Changxing has previously calculated that the output of Humanity Base No. 1 is enough to consume approximately 50 adults and dozens of young children. But now, the second generation of children is about to become adults - in fact, their current appetite is no more than that of adults.
The number of people is small, so in this calculation, adults can be counted as 41 people. Plus 60 children, although the output of Base 1 can still be sustained, there is very little food that can be saved for storage. Some
We can no longer make ends meet in terms of food categories. Fortunately, there are previous reserves in the storage area, which can temporarily support us.
Just seeing that some categories can only be exported, and the number of categories that can be saved and imported is getting smaller and smaller, Zhao Changxing always feels as if a knife is cutting his own flesh.
Rice and wheat each have a planting area of 2,000 square meters. These two crops can use a double-layer planting method to maximize the use of space, which is a planting area of 4,000 square meters each.
With 4 rounds of planting in a year, wheat can produce about 3.5 tons, which is 14 tons. Rice can produce about 5 tons in one round, which is 20 tons in a year.
With this year's 34 tons - minus about 4 tons of losses 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 30%. The final harvested flour is the same as
The total amount of rice is 21 tons.
Based on the average daily consumption of 0.5 kilograms of staple food by an adult with sufficient non-staple food, the annual output of 21 tons is enough to feed 120 adults. Not to mention the 30% loss.
That is, bran, rice bran, etc. - about 9 tons in weight, are not thrown away directly. They are also excellent feed and will be turned into meat when fed to livestock, and will also become part of the human diet.
In general, the planting of rice and wheat in Planting Workshop No. 2 will greatly reduce the pressure on food demand from population growth. Based on the current population growth rate, at least for 30 years, Zhao Changxing will no longer have to worry about food shortages.
question.
The cultivation of three crops, green storage corn, rice, and wheat, takes up 7,000 square meters of the No. 2 planting base. There is still 2,200 square meters left for use.
Vegetables will definitely not be considered. The vegetables produced in the vegetable growing area of Base No. 1 are enough for consumption. After all, this thing has high yield, small area and fast growth. At the current stage, there are endless vegetables to eat.
Use it directly as feed for livestock.
Among these areas, an area of 200 square meters has been divided, and it is planned to plant various fruit trees, such as apples, pears, grapes, bananas, etc., to enrich people's diet. Another 1,000 square meters is used to grow soybeans, with an annual output of approximately
It looks like about 4 tons.
The last 1,000 square meters left were used to grow some miscellaneous things, such as cotton, peanuts, rape, sesame, sunflower, sugar beets, sugar cane, etc.
Some people have also made suggestions that the cotton planting area should be expanded to develop light industry, especially the cotton spinning industry. After all, the Spark spacecraft does not carry too many clothes, quilts and other materials, and these things must be produced by ourselves. And
At this stage, even if the newly born children are allowed to pick up the old clothes worn by their older brothers and sisters, the number of clothes will soon be insufficient.
Adults generally only have two sets of clothes, both of which are very old. People are looking forward to having a few new clothes to wear.
But this request was cruelly rejected by Zhao Changxing. He believed that under the premise that all human activity areas have sufficient temperature control facilities, there is no need for the warmth function of clothing. Then only aesthetics and body covering are left.
Function. These two functions can be done by old clothes. There is really no need to waste precious planting area at this stage.
Even if the cotton grown right now is not used to make clothes, it is used for industrial purposes.
This makes both the first generation of young people, the second generation of teenagers, and even the third generation of children unhappy. There is no other way, Zhao Changxing has to promise to build the No. 3 planting base as soon as possible in the future, and to produce large quantities of
People reluctantly accepted the idea of growing cotton to develop light industry.
The internal construction of the No. 2 planting base has begun vigorously. With an area of 10,000 square meters, if Zhao Changxing were to do it by himself, it would be impossible to complete it in several years. But the addition of helpers shortened this time to the original
A fraction.
In just one year, the internal construction has begun to take shape. At this time, the second batch of humans have also reached adulthood and it is time to put into work.
Zhao Changxing and the first generation of humans welcomed them to Base No. 1 and assigned their own rooms. At this point, all 20 rooms in Base No. 1 were occupied, and there was even one more person who had no place to live.
Many people offered to find a place in the leisure and entertainment area or industrial area and set aside a house for Zhao Changxing to live in, but Zhao Changxing firmly refused. He believed that as the oldest person among all
He is also the de facto "leader" of all human beings at this moment. He has the obligation to set an example. So he chose to live in the leisure and entertainment area, allowing everyone from the first and second generations to live there.
Arrived inside the room.
With the addition of the second batch of 30 adult humans, the construction of the No. 2 planting base was once again accelerated, 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, automated planting, maintenance, harvesting modules, etc., have all been installed. Various substances required for preparing nutrient solutions have also been installed.
The collection has been completed, and the substrate used to fix the crop roots has been spread on top of the petri dish.
Followed by a total of 40 people, Zhao Changxing came to the No. 2 planting base with great joy. Standing on the corridor, Zhao Changxing solemnly pressed the start button. Then the next moment, the temperature control and humidity control equipment began to operate.
, the different planting areas were adjusted to different climates. The automatic planting equipment began to operate, sowing the seeds of many crops into the substrate.
"Soon, we will be able to harvest a lot of food..."
