Doomsday Bunker Upgrade Chapter 29: Growing Greenhouse
The planting greenhouse in the Chenxin Refuge is not large, only one hundred square meters, or one are, one sixth of an acre.
Here, Chen Xin actually made a mistake. When he was building the planting greenhouse, the construction team asked him how much area he wanted to build, but he turned the ares into acres, so that the area of the planting greenhouse was six times smaller. .
In Chen Xin's original plan, it was used to grow upland rice and vegetables, and to provide him with food to ensure his normal consumption and exchange for resources.
But now because the area is wrong, the output is far from enough.
The yield per mu of upland rice is about nine hundred catties, and the yield of rice after shelling is about seven hundred catties, and one are is only equivalent to about one-sixth of an acre of land, and the yield is just over one hundred catties.
The total amount of rice that an adult needs to eat in a year is about 300 catties, in addition to eating about the same amount of vegetables and meat, in short, if Chen Xin wants to make himself If his body is maintained in a healthy state, then he must eat at least a total of about 500 to 600 catties of food a year.
Considering that the surface temperature will drop to tens of degrees below zero in the future, enough food is the guarantee of the human body's caloric source. I am afraid that the consumption of food will only be more than this, not less.
The conditions are limited in the last days, and the meat is not expected to be old, but even if it is only vegetables and rice, with Chenxin, a greenhouse of only 100 square meters, even if he can plant two crops of dry rice a year, all The harvest lasts a year, which is only 300 catties of rice. There is no place to grow vegetables.
Three hundred catties of rice could not meet the food needs of Chen Xin in the next year no matter what.
In Chen Xin’s original plan, he planned to plant half an acre of dry rice to ensure enough for himself, and the other half acre to plant some vegetables such as carrots, cabbage and lettuce, so that he could have surplus besides eating himself. The output can be exchanged for other shelters for resources.
After all, the end of the world is coming. There is no sunlight on the surface and the temperature drops to tens of degrees below zero. The planting of crops and vegetables already depends on these planting greenhouses.
There are planting greenhouses that can grow some food and vegetables. This is a guarantee for their quality of life and food supply. At least Chen Xin can survive on this planting greenhouse when there is no other food source.
And in the apocalyptic era, if Chen Xin can have a stable channel to produce vegetables and fruits, it will be a very reliable source of income in the near future.
At that time, it is a very viable option to exchange fresh vegetables for other food and materials, and even the gasoline needed for power generation.
This is like the dungeon in "Wandering Earth". Everyone eats food made of earthworms. You suddenly take out fresh fruits and vegetables. This is definitely worth a lot of good things.
In Chen Xin’s original plan, half of this acre of land was planned to grow upland rice and half to grow vegetables and fruits. This would not only meet his own consumption, but also some of the surplus could be exchanged for supplies.
It's just that because of a calculation error, he calculated one are into one acre, and the yield was only one-sixth of the original. It was not enough to meet his own consumption, so how could he have excess output to exchange for materials?
Chen Xin has carefully calculated that if he wants to meet his one-year food consumption, then the area of the entire planting greenhouse must be doubled. Three to four times the size is now possible.
Originally, it was impossible for Chen Xin to expand the planting greenhouse. Although the greenhouse is not a container house, the four walls of Chen Xin asked the construction team to make insulation walls and pour cement. If it is expanded, at least the walls must be installed. Cut off one side, and then slowly dig with a shovel.
Although there is nothing to do in the refuge, Chen Xinshao said to dig a 100-square-meter greenhouse for a month or two.
As for the subsequent wall insulation, let alone, he didn't even have any construction materials.
But now with the system, all this is completely different.
"Simple Planting Greenhouse"
"Upgrading plan 1: Increase drip irrigation system, increase hydroponic planting tray, crop yield +10%, irrigation water consumption -10%, upgrade requires 2000 survival points"
"Upgrading plan two: increase planting area, increase lighting efficiency of supplementary light, crop yield +10%, lighting time -10%, upgrade required survival points 3500"
The two upgrade plans are different, but both can increase the planting area of the greenhouse.
The hydroponic planting plate added in the first plan is set up in the air. If the original 100 square meters planting greenhouse is turned into two layers, the land on the lower layer is planted with dry rice, and the hydroponic plant plate on the upper layer is planted with vegetables. Coupled with the 10% increase in crop yield obtained from the upgrade, this is enough to satisfy Chen Xin's own food consumption.
As for the second plan, it was the same as Chen Xin’s original idea. One wall was removed to expand the entire planting greenhouse, and the area was upgraded from one hundred square meters to two hundred square meters, so as to meet Chen Xin’s personal consumption needs. , But compared with the first scheme, the space utilization rate is obviously lower.
And the first option also adds a drip irrigation system. This irrigation method is the most water-saving way~ IndoMTL.com~ This method can achieve 95% water resource utilization. It was originally used It is used for irrigation in arid areas. For Chen Xin, who is difficult to obtain water supplements in the end of the future, this method will undoubtedly save him a lot of water that would otherwise be consumed.
However, the improvement in the lighting efficiency of the supplementary light in the second upgrade plan also made Chen Xin a little concerned.
fill light is a kind of lamp used to simulate the sunlight, and most of the greenhouse plants need this kind of equipment to supplement the light of the plants.
Because many times the light conditions are not ideal, it will affect the growth of plants, especially the planting of some precious or delicate plants. The daily light time has different requirements for different growth stages, so this must be used To fill light to supplement the lighting time.
Chen Xin installed four supplementary lights in the greenhouse. Turning on for twelve hours a day can completely replace natural light, which can reduce the light time by one hour and save a lot of electricity.
Now the area is small, this saving effect is not visible, but if the planting area is expanded and the number of supplementary lights increases, the energy saving effect will be obvious.
But currently Chen Xin is still accumulating survival points at 10 o'clock a day, and asked him to spend two or three thousand points to upgrade the greenhouse. He obviously does not have the savings to upgrade the room.
So at present, Chen Xin can only make an upgrade plan based on the upgrade cost and importance of different rooms. As for the real upgrade of these rooms, Chen Xin thinks it may take at least a year.
Of course, if Chen Xin chooses to upgrade some equipment or items instead of upgrading the room as a whole, then he can save almost one more month to upgrade.
Just considering the price/performance ratio, Chen Xin still doesn't want to upgrade by only upgrading a single item.
