It's already July.
Five days without rain will cause a minor 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 was in ruins, and many former farmlands were covered 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, the dry weather that lasted for a month 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 largest water source is consumed, 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: In theory, drip irrigation does save water, fertilizer, labor and effort.
However, there are many problems in actual operation. The first is that the dripping head is easy to get clogged. There are still basic requirements for the quality of water used for drip irrigation. At least it must be clean and free of impurities.
Field crops are grown twice a year, and the sowing pattern is complicated. 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 dragging them around in the soil will easily block the drip irrigation holes.
Just like field crops such as corn, wheat, peanuts, sweet potatoes, potatoes, beans, etc., they all need to plow the soil, harrow and then re-arrange 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. Whether it is suitable or not cannot be said on paper. It must be adapted to local conditions.
Is it convenient to harvest from planting? Are there external conditions? Is the cost enough? Consider various aspects such as this 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. 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 dripper 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 had no intention of using drip irrigation equipment from the beginning. The reason why we chose to build the base here is because there is a large mountain pond here. 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 has to be released from mountain ponds every 3 to 5 days.
Fortunately, now the entire mountain pond is no longer used to irrigate the farmland of each household, but is only concentrated on these few acres of farmland in this base. The consumption is not that exaggerated.
Hot days continue, 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 base's future development plan. One is to continuously expand its sphere of influence. The advantage is that with more people, things can be done easily, and with strong strength, we can better protect ourselves. The disadvantage is that the core issue of everything cannot be circumvented by the word food. In these apocalypse, 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 there are fewer people and it is 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 personnel. At the same time, it gained more firearms firepower in the early stages.
But sooner or later the bullets will run out. Looking at this apocalyptic world, a natural disaster will happen from time to time, which can easily cause some groups to collapse.
Many years after the end of the world, there are heavy rains, droughts, blizzards, and cold. Keep destroying the world. A lot of industrial equipment was 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 was reborn, 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.
Another evening, Li Yu walked to the field to observe the rice and corn planting conditions.
Before I even got closer, 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, if 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. We don't know when this drought season will end, eh. 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 reborn memory, this drought lasted for two months. Now the water in the mountain pond alone can be used until the drought is over.
"Grandpa, let me help you." Li Yu also rolled up his trouser legs, got out of the field, and repaired some small gaps on the edge of the field. Prevent water from flowing out. You must know that water is precious now, and all this water must be used to grow crops. Letting water from these gaps flow out 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 war, drought, or 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 who want to try growing crops, but cannot withstand this long drought.
The crops eventually withered, and they were desperate, needing to prepare in advance while they still had some food.
In the end, they were forced to look for food elsewhere.
