2. Acid rain can accelerate the loss of mineral nutrients in the soil. Under the action of acid rain, the soil’s nutrients, including potassium, sodium, calcium, and magnesium, are lost and washed away with the rainwater.
This ti, prolonged acid rain will cause a large amount of nutrients to leach from the soil, resulting in a severe deficiency of nutrients, making the soil barren. It changes the soil structure, leading to soil impoverishnt and affecting the normal developnt of plants.
According to An Ya’s preliminary estimation, the most important harm caused by this acid rain is the soil becoming barren.
If we wait for the land to recover naturally to its fertile state before the acid rain, it will take a full two years...."
Before he could finish, the crowd erupted into chatter.
"Two years, does this an we can’t grow crops for two years?"
"That’s too long! Who knew that acid rain could damage the land so badly, really, it’s too!!!"
....
"Is there any solution, Xiao Yu? This is indeed a big problem. If we can’t grow crops for two years, although reserves aren’t a problem, it will severely affect the base’s developnt." Second Uncle said, frowning, as he heard this for the first ti.
Li Yu saw everyone getting so worked up and discussing the matter.
He smiled and gestured to them to calm down, saying, "Everyone, don’t get agitated, wait until Li Gang finishes speaking. He’s not done yet."
Li Gang coughed slightly and continued:
"I haven’t finished yet, just pointed out the problem. An Ya has proposed so rediation asures against the harm acid rain has caused to the land.
These focus on three aspects: strengthening soil restoration, rational fertilization, and afforestation.
For soil restoration, we need to use tractors to loosen the compacted land.
On the fertilization front, the volcanic ash that had previously fallen is rich in fertility, and can be mixed or directly covered on the soil surface for imdiate cultivation.
Additionally, we can plant pasture on the acid-rain-corroded ground to protect the land.
Moreover, the septic tanks in our base are actually natural and excellent fertilizers.
With this series of asures, she estimates that restoration can be completed in about two or three months.
However, she also ca up with a suggestion.
Given the unpredictable weather today — cold, heat, acid rain, snowstorms, darkness, and other factors difficult for us to evaluate — she proposed two suggestions.
One is to build greenhouses, and the other is to expand indoor farming.
This way, we can reduce planting problems caused by external factors."
Li Gang finished speaking in one go, without anyone interrupting his speech.
Second Uncle looked at Li Gang and asked, "Are you finished?"
Li Gang nodded and replied, "Finished. That’s all."
Second Uncle nodded and added, "Well, as everyone knows, in today’s environnt, the importance of food is undeniable. Our base has developed to this point due to ample food supplies, with food being at the core of the four-rank system.
Without food, there is nothing.
Therefore, I believe the base must seriously consider food production, ensuring stable output.
These past two years, we’ve been lucky with relatively stable yields.
However, natural disasters are unpredictable, which is why my thoughts align with An Ya’s — building greenhouses. Constructing more durable greenhouses."
Li Yu also stepped forward and supplented, "This issue really needs to be prioritized. Currently, the indoor planting area in the base only accounts for forty-five percent of the total planting area. I think this ratio can be expanded."
Yang Tianlong scratched his head and said to Li Yu, "Food is a big problem. Actually, for these past few months, all that land outside has been wasted, depending on the weather for harvest.
But the indoor farms are unaffected by external conditions."
Ding Jiu considered other factors, wondering what kind of greenhouse to construct if building one?
Also, expanding the indoor farms is best done underground, where there’s soil, which can retain and isolate heat.
This greatly saves energy.
So he stood up and said, "Director Li, I have no objections to building outdoor greenhouses, but this requires so materials. And if we’re expanding indoor farms, how large should it be, and where should it be built? These two issues involve construction ti and difficulty."
Li Yu raised his eyebrows and asked, "Last ti, I constructed in the cave over there. Due to short ti, I built only less than ten acres of cave there.
With over two hundred acres of forest, developing a ten-acre cave shouldn’t be a problem, right?"
Ding Jiu nodded and confidently said, "No problem. We could even develop twenty acres. My suggestion is to excavate in the mountainside.
This way, both up and down can be excavated. If we dig ten ters, later in the cave, with reinforced concrete, we can create two levels, reaching forty acres.
Of course, if only twenty acres are needed, ten acres of dig area should suffice by then."
Last ti, Li Yu learned a lot of knowledge in the cave, realizing that bunkers are best built within caves.
Adapting to the terrain strengthens stability and closure.
Most importantly, it saves materials.
Having discussed this, Li Yu then said to everyone, "Alright, let’s take a vote. Should the base construct outdoor greenhouses and expand indoor farms?"
