Five days without rain will cause a drought, ten days without rain will cause a major drought, and a month without rain will cause smoke.
After the heavy rain, it has not rained for a month.
The entire land is in ruins, and many former farmlands are filled with ravines.
In the base, due to the advance storage of water in the previous mountain pond, the water level of this mountain pond was raised to the highest level.
At this time, a month of continuous dry weather has caused the water in this mountain pond to decrease day by day.
At this time, the water in the mountain pond has been reduced by one-third.
In this base, everyone has saved water, but in farmland, the most consumed water resources are, but at this stage, this is a last resort.
Li Yu is very clear about the advantages and disadvantages of drip irrigation. In terms of benefits, theoretically speaking, drip irrigation does save water, fertilizer, labor and effort.
However, there are many problems in actual operation. The first one is that the hair head is easy to block when dripping. There are still basic requirements for the quality of water used for drip irrigation. At least it must be clean and free of impurities.
Planting field crops requires two seasons a year. The sowing pattern is complicated, and it is too troublesome to constantly dismantle and install drip irrigation equipment.
Crops installed with drip irrigation must not be harvested by mechanized cultivation, otherwise it will be troublesome to disassemble and disassemble, and it will be easy to block the drip irrigation holes by dragging them around in the soil.
Just like field crops such as corn, wheat, peanuts, sweet potatoes, potatoes, beans, etc., they all need to plow the soil, harrow and then rearrange the fields for planting. Installing dripper equipment is not labor-saving but labor-intensive.
All in all, it also depends on whether the crops are suitable for drip irrigation. All factors must be considered. It is not just about whether the crops are suitable or not. It must be adapted to local conditions.
Is it convenient to plant and harvest? Are there external conditions? Is the cost sufficient? A variety of aspects must be considered comprehensively.
The most important thing in this apocalypse is to survive, so the staple food to meet the needs is nothing more than rice, corn, wheat, sweet potatoes, and potatoes.
Drip irrigation cannot be used for rice, because it needs to be planted in water, and simple drip irrigation cannot meet the growth of plants.
Potatoes, corn, etc. all need to plow the soil, harrow and then re-arrange the fields for planting, and install drip pipe equipment, which is laborious and time-consuming.
Moreover, dry weather like this may occur for a long time, but the place where Li Yu lives is in a subtropical monsoon climate, and the rainfall throughout the year is quite abundant.
Therefore, Li Yu did not plan to use drip irrigation equipment from the beginning. The reason why he chose to build the base here is because there is a large mountain pond here that can meet the use of water sources.
Now, we are just waiting for the dry season to pass and the rainy season to come.
In farmland, under the sun, the water in farmland evaporates very quickly. Basically, water needs to be released from mountain ponds every 3 or 5 days.
Fortunately, now the entire mountain pond is no longer used to irrigate the farmland of each household, but only the few acres of fields in this base. The consumption is not that exaggerated.
Hot weather continues, and droughts occur everywhere.
Scenes of survivors relocating due to water source problems continue to occur.
During the relocation process, some people died on the road due to exhaustion; some people died of heatstroke without receiving effective rescue; and some people starved to death.
In the base, a competition is taking place in full swing.
In Li Yu's plan, there are two paths for the future development of the base. One is to continuously expand the sphere of influence. The advantage is that it is easier to do things with more people, and it is stronger and can better protect itself. The disadvantage is that the core problem of everything is
, the word food cannot be avoided. In these last days, if there is not enough food, no matter how many people there are, they will be a burden.
Another way is to take the route of elite soldiers, where all the people are soldiers, and among the limited personnel, the overall power is increased. The advantage is that fewer people are easier to manage, and the pressure of food is not so great. The disadvantage is that the overall strength is definitely not as good as that of a group with a large number of people.
.
Li Yu is currently taking the second path, improving the overall quality of his personnel. At the same time, he has gained more firearms firepower in the early stages.
But sooner or later the bullets will run out. In this apocalyptic world, natural disasters may occur from time to time, which can easily cause some groups to collapse.
Many years after the end of the world, heavy rains, droughts, blizzards, and cold continued to destroy the world. Many industrial equipment were destroyed.
It also allowed mankind to gradually enter the age of cold weapons.
Human civilization is gradually destroyed.
In the face of the most critical survival, food is the fundamental factor in reaching the end.
Only by maintaining a sufficient food supply can you truly survive.
Li Yu, who came back from rebirth, knew one thing very well.
There is no superpower in this world, and there is no son of the era who can lead mankind to rebuild civilization.
Some are just endless despair and endless sadness.
Human beings can only survive in this apocalyptic environment with difficulty.
Another evening, Li Yu walked to the fields to observe the planting conditions of rice and corn.
Before I even got close, I saw my grandpa rolling up his trouser legs, going to the fields to block the fields, and repairing some small gaps on the side of the fields.
Hearing the footsteps, grandpa straightened up, raised his head and saw it was Li Yu, and said, "Xiaoyu, why are you here?"
"Grandpa, the weather is so hot, you should go out less often to avoid heat stroke. I'm here to take a look at the crops." Li Yu replied.
Grandpa wiped the sweat with the towel on his shoulder, with anxiety in his eyes: "The water on the mountain pond is getting less and less. I don't know when this drought season will end. Well. Your second uncle said that we had to fight before
The water in the well has also decreased a lot. This is not a good sign."
Hearing his grandfather's worried words, Li Yu was also a little worried. According to his rebirth memory, this drought lasted for two months. Now the water in the mountain pond can be used until the drought ends.
"Grandpa, let me help you." Li Yu also rolled up his trouser legs, went to the field, and repaired some small gaps on the edge of the field to prevent water from flowing out. You know, water is precious now, and all this water must be used to grow crops. Let these
The water flowing out of the gap is undoubtedly a waste.
Now, many flowers and plants in the garden have dried up and died.
Except for the few large sweet-scented osmanthus trees, which were occasionally watered, other flowers and plants could only be allowed to wither.
In this world, every time there is a war, every drought, or a food crisis, there will be population migration.
Even the last days are no exception.
In a place far away from the base, there is a huge group that is migrating south.
They didn't know where they were going, but they stayed where they were, waiting to die.
The materials in the original place have been looted, and many people can only move to other places.
There are also some groups that want to try growing crops, but cannot withstand this long drought.
The crops finally withered, and they were desperate. They needed to prepare in advance while there was still some food.
In the end, I was forced to look for food elsewhere.
