Time is still passing by in a hurry while Zhao Changxing is busy. The children are growing up day by day, which can also be noticed from the increase in their appetite. Fortunately, the soilless cultivation workshop is now in full operation, and the grain output
It was completely sufficient and did not put any pressure on Zhao Changxing.
Otherwise, the problem of feeding the children alone would be enough to give him a headache.
Humanity Base No. 1 is also showing its appearance bit by bit.
At this moment, in addition to the five completed buildings of the soilless cultivation workshop, livestock breeding workshop, life support area, fully automatic nutrient solution preparation workshop, and warehouse area, the sixth building is about to be completed.
This sixth building is called the garbage recycling and processing center. After the completion of Base No. 1, the waste in all other areas, such as chicken manure and pig manure produced in the livestock breeding workshop, and crops grown in the soilless cultivation workshop, will be harvested after the fruits are harvested.
Afterwards, abandoned plants, domestic garbage produced in the living area, bones, human feces and other items will all be transported here for further processing.
The reason for building a garbage recycling and processing center is not that Zhao Changxing wants to do some environmental protection on Sedna, but that there will be many recyclable things in these discarded garbage. At this stage of shortage of materials,
, it is very necessary to recycle them to achieve a "closed loop of energy and materials" within the base.
For example, chicken manure, pig manure, fish manure and other things can be used as nutrient solution for plants after treatment, human food waste can be used as livestock feed after treatment, and crop plants can also be used as feed after treatment.
A portion of nutrients is collected from Sedna and is first used by various crops after deployment. Their output is used for livestock, aquatic products and human consumption, and the excrement of livestock, aquatic products and humans can be returned and used for crops again.
Growth and utilization, thus forming a "closed loop of energy and materials" effect, which can greatly improve the utilization rate of materials and greatly reduce Zhao Changxing's workload.
Before the garbage recycling and processing center was built, Base No. 1 also operated according to this logic, but it required Zhao Changxing's in-depth participation to complete it. After the garbage recycling and processing center was built, he would be freed from this process and everything could be done.
Leave it to Xiao Xi to do it.
The construction of this sixth building took Zhao Changxing more than three months. After it was completed, Zhao Changxing could finally start the construction of the livestock and aquaculture workshop.
Animal husbandry and aquaculture workshops will produce a large amount of feces, bones, inedible body structures such as lymphatic viscera, feathers, sewage rich in organic matter, etc. The amount is so large that Zhao Changxing cannot complete the processing work with manpower. This, too
This is one of the reasons why Zhao Changxing must complete the garbage recycling and processing center before officially starting to breed animals.
Zhao Changxing plans to divide the livestock and aquaculture workshop into eight parts. Chickens, ducks, geese, pigs, cattle and sheep each occupy one part, the four major fishes occupy one part, and aquatic plants occupy one part. Among these eight parts, the chicken's
The status is more important. It occupies an area of 200 square meters, and ducks and geese occupy 50 square meters. This area can be used to raise about 800 chickens, 100 ducks, and 50 geese. Some of them produce meat, and some of them produce eggs.
, so there are meat and eggs.
Excluding unexpected situations such as illness, under ideal circumstances, Zhao Changxing can obtain approximately 60,000 eggs, 2 tons of chicken, 1,000 duck eggs, 0.5 tons of duck meat, 1,000 goose eggs, and 0.3 tons of goose meat every year.
Pork is undoubtedly one of the most important food types. Zhao Changxing plans to allocate an area of 400 square meters for the pig breeding area. After adopting the double-layer breeding method, he will also set aside the area required for the installation of breeding pigs, sows, and various equipment.
, this area can build about 80 pig houses and stock 80 pigs at the same time. Calculated based on the 7-month slaughter time, and assuming that all piglets grow up successfully, Zhao Changxing can obtain about 8.5 tons of pork every year.
Excluding the four types of animals, chickens, ducks, geese, and pigs, there are still 300 square meters of livestock and aquaculture area left. Among them, Zhao Changxing plans to allocate 100 square meters for cattle and raise 4 of them, including two dairy cows and two beef cattle.
.
Considering various factors, if beef cattle are slaughtered in one year, two beef cattle can produce 0.5 tons of beef in one year.
The sheep breeding area is also 100 square meters. This area can raise about 30 sheep. Calculated on a half-year basis, the annual output of mutton is about 0.6 tons.
There are still 100 square meters left, of which 50 square meters are allocated to fish. Zhao Changxing plans to build a fish pond, which can produce several hundred fish every year. The remaining 50 square meters will also be built into a pond to cultivate some kelp and lotus root.
Algae and other miscellaneous things.
All in all, the livestock and aquaculture area can produce about 13 tons of various meats annually. But this is under the premise of operating at full power, and food needs to be adequately supplied.
At this stage, Base No. 1 obviously does not have such sufficient food. You must know that even with various vegetables, the total annual food output of the soilless cultivation workshop is just over 10 tons, which is not enough to be made into feed.
eat.
"In current calculations, including all crop plants, such as corn stalks, rice stalks, soybean stalks, wheat straw, etc., and adding some grain, it can support about 30% of the total production efficiency of the livestock breeding workshop. Any more, it will be
It will have an impact on grain reserves. This efficiency is a bit low."
In the original base planning, the livestock and aquaculture area could not reach the level of full-power production. This requires Zhao Changxing to lead a new generation of humans to build more and larger soilless cultivation workshops on their own. With enough
Grain production can only be achieved later. But now, Zhao Changxing is not satisfied with this situation.
Just thinking about the 30 babies that will be born in a few years, he is extremely eager to store more meat and more food in the warehouse.
After all, if you have food in your hands, you won’t panic in your heart.
"I'll think about it again... well, the only way now is to use a starch reactor to directly synthesize starch to use as feed."
However, this technology is not yet mature. There was no technology for large-scale synthesis of starch on Earth at the time. Otherwise, there would have been relevant equipment in the Spark spacecraft.
"I only have two reactors now, and I can only synthesize a few kilograms of starch every day, which won't do much good. It's not realistic to build more reactors. Alas."
After much thought, Zhao Changxing had to regretfully accept the reality that the livestock and aquaculture area could only operate at 30% power at this stage. In this way, the annual output would become about 20,000 eggs and 3.5 tons of meat.
appearance.
Because of the reduction in output, Zhao Changxing no longer needs to build the entire livestock and aquaculture area now. He only needs to build a part of it, which is enough for current use. This saves a lot of time, and it only took about half a year to complete the entire area.
As a result, a new batch of chickens, ducks, geese, pigs, cattle and sheep were put in and began to grow slowly under the supervision of the fully automatic breeding system.
After initially completing the "energy and material closed loop", the construction of Base No. 1 once again entered a new level. Next, Zhao Changxing began the construction of another extremely important area in Base No. 1.
Living Area.
Right now, the population is relatively small, and the children are still too young, so living in the Spark spacecraft can be maintained. But when the population increases in the future, living in the Sedna Base No. 1 will become inevitable.
In Zhao Changxing's plan, the new generation of humans will live in the Fire spacecraft when they are under 18 years old, and when they reach 18 years old, they will move here. The reason for doing this is mainly to prevent Seder
The reason why Naxing's low gravity environment affects the growth and development of children.
The maximum supply of materials produced by Base No. 1 can support a population of about 200 people, including about 40 adults, and more than 100 babies, young children and teenagers. If there are more, there will be famine and starvation.
To sum up, 40 people need to live in the living area of Base No. 1. According to a room of 20 square meters and two people living there, 40 people will need a living area of at least 400 square meters. In addition, people's entertainment areas need to be planned.
Including the canteen, leisure area and other places, including corridors and other areas, as well as the area occupied by the building, the total area of the living area is as high as 3,000 square meters, which is larger than a soilless cultivation workshop.
But there is no way. We cannot let people live in small pigeon cages. This will cause psychological problems over time.
At this moment, including the six previously completed buildings and the current living area, the total area has reached about 8,000 square meters.
After the livestock and aquaculture area was put into operation, Zhao Changxing had no time to rest and once again devoted himself non-stop to the construction of the living area.
This is the largest building in Humanity Base No. 1 so far. Zhao Changxing knew that this project would definitely consume a huge amount of time, so he did not rush at all during the construction process and just followed the steps.
As time goes by, the built-up area of the living area is getting larger and larger. In this process, due to the different growth cycles of various crops, chickens, ducks, geese, pigs, cattle and sheep, each period is not long.
Time, there will always be a time when a crop or animal will be harvested.
This is the happiest time for Zhao Changxing, as if his exhausted body after a busy day can burst out with strength again. At this time, Zhao Changxing will always take some time to watch the food or meat being really eaten.
Put it in the warehouse and reserve it before giving up.
Today is the time for corn harvest. The harvest time is set at five o'clock in the afternoon. And the time is only 4:45, and Zhao Changxing has already arrived at this corn.
Looking at the tall and straight corn trees with huge and plump fruits, Zhao Changxing couldn't help but smile on his face.
