The planting greenhouse in Chen Xin's shelter is not large, only one hundred square meters, which is one acre, or one-sixth of an acre.
Chen Xin actually made a mistake here. When he was building the greenhouse, the construction team once asked him how much area he wanted to build. As a result, he calculated acres as acres, so that the area of the greenhouse was six times smaller.
In Chen Xin's original plan, this place was to be used to grow upland rice and vegetables, providing him with food that he could consume normally and exchange for resources.
But now because the area is wrong, the output is far from enough.
The yield of upland rice per mu is about 900 kilograms, and the yield of rice after shelling is about 700 kilograms. One acre is only equivalent to about one-sixth of an acre, and the yield is just over 100 kilograms.
The total amount of rice that an adult needs to eat in a year is about three hundred kilograms. In addition, he also needs to eat a similar amount of vegetables and meat. To put it simply, if Chen Xin wants his body to maintain In a healthy state, he must eat at least a total of about 500 to 600 kilograms of food a year.
Considering that the surface temperature of the earth will drop to tens of degrees below zero in the future, enough food is the guarantee of the human body's heat source. I am afraid that food consumption will only be more than this, not less.
In the apocalyptic situation, conditions are limited, and Chen Xin has no hope of meat. But even if it is just vegetables and rice, with Chen Xin's greenhouse of only 100 square meters, even if he can grow two crops of upland rice a year, all the harvest will be enough. That's just three hundred kilograms of rice a year, and there's no place to grow vegetables.
Three hundred kilograms of rice cannot satisfy Chen Xin's food needs for a year.
In Chen Xin's original plan, he planned to plant half an acre of upland rice to ensure that he could eat enough for himself, and the other half acre of land to grow some vegetables such as carrots, cabbage, and lettuce. In addition to eating for himself, he would also have a surplus output to take home. Go to other shelters to exchange resources.
After all, the end of the world has come, there is no sunlight on the surface of the earth, and the temperature has dropped to dozens of degrees below zero. The cultivation of crops and vegetables has all depended on these greenhouses.
Having a greenhouse to grow some food and vegetables is a guarantee for his quality of life and food supply. At least Chen Xin can rely on this greenhouse to survive when there are no other sources of food.
Moreover, in the apocalyptic era, if Chen Xin can have a stable channel for producing vegetables and fruits, this will be a very reliable source of income in the near future.
At that time, it will be a very feasible option to exchange fresh vegetables for other food and materials, or even the gasoline needed for power generation.
This is like the dungeon in "The Wandering Earth". The food everyone eats is made of earthworms. If you suddenly take out fresh vegetables and fruits, you can definitely get a lot of good things.
In Chen Xin's original plan, half of this acre of land was planned to be planted with upland rice and half with vegetables and fruits, so that he could not only meet his own consumption, but also have some left over to exchange for supplies.
But because of a calculation error, he counted one acre as one acre of land, and the output was suddenly 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 supplies
Chen Xin has carefully calculated that if he wants to meet his food consumption for a year, the area of the entire greenhouse must be at least doubled. If he wants to have excess output to trade for supplies, he must have at least three of the current greenhouses. It is only possible to reach four times the size.
Originally, it was impossible for Chen Xin to expand the greenhouse. Although the greenhouse is not a container house, Chen Xin also asked the construction team to make insulated walls and pour cement. If he wanted to expand, he would have to knock down at least one wall. , and then dig slowly with a shovel.
Although there is nothing to do in the shelter, Chen Xinshao said it would take a month or two to dig out a 100-square-meter greenhouse.
As for the subsequent wall insulation, let alone the following, he didn't even have construction materials.
But now with the system, everything is completely different.
"Simple Grow Greenhouse"
"Upgrade plan one: add drip irrigation system, add hydroponic planting tray, crop yield +10%, irrigation water consumption -10%, upgrade required survival points 2000"
"Upgrade plan two: increase the planting area, improve the lighting efficiency of the fill light, increase the crop yield by 10%, and reduce the lighting time by 10%. The survival points required for upgrade are 3500."
Both upgrade options are different, but both increase the greenhouse’s growing area.
The first plan adds hydroponic planting trays that are mounted in the air. It is like turning the original 100-square-meter planting greenhouse into two floors. The lower layer of land is used to grow upland rice, and the upper layer of hydroponic planting trays is used to grow vegetables. With the upgrade The 10% increase in crop yield obtained is enough to satisfy Chen Xin's own food consumption.
As for the second option, it is the same as Chen Xin's original idea, which is to knock down one wall and expand the entire greenhouse, upgrading the area from 100 square meters to 200 square meters. This can also meet Chen Xin's personal consumption needs, but it is not as good as Starting from the first option, the space utilization rate is obviously lower.
Moreover, the first plan also adds a drip irrigation system. This irrigation method is the most water-saving method. This method can achieve 95% water utilization rate. It was originally used for irrigation in arid areas. For Chen Xin, who will have difficulty replenishing water resources in the future, this method can undoubtedly save him a lot of water resources that would otherwise be consumed.
However, Chen Xin was a little concerned about improving the lighting efficiency of the fill light in the second upgrade plan.
Fill light is a kind of lamp used to simulate sunlight. Most greenhouse cultivation requires this kind of equipment to supplement the light of plants.
Because many times the lighting conditions are not ideal, it will affect the growth of plants, especially when planting some precious or delicate plants. Different growth stages have different requirements for daily lighting time, so supplementary light must be used. lights to supplement the lighting time.
Chen Xin installed four fill lights in the greenhouse, which can completely replace natural lighting when turned on for twelve hours a day. This can reduce the lighting time by one hour and save a lot of electricity.
Now that the area is small, this saving effect cannot be seen, but if the planting area is expanded and the number of fill lights is increased, the energy saving effect will be obvious.
However, Chen Xin is still saving survival points at 10 o'clock a day, and he is asked to spend two to 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 actual upgrade of these rooms, Chen Xin thinks it will take at least a year.
Of course, if Chen Xin chooses to upgrade certain equipment or items instead of upgrading the room as a whole, then he will be able to save for a few months to upgrade just once.
After considering the cost-effectiveness, Chen Xin still didn't want to upgrade only a single item. (End of chapter)
