Gu Qingling asked: "But why do they have to be buried 10 centimeters? Can't they be buried deeper or shallower? And they have to be placed on the tidal flat. Can't they be buried in a drier or wetter place? They breed in summer and autumn, why?
Not choosing winter? Why can't we see larvae in winter, but only in spring..."
Several questions were thrown out in succession, and everyone used their brains to answer them.
Everyone has taken an agronomy class and knows that animals, like plants, need environment, temperature, humidity, and even sunlight.
The lack of any thing may cause the plant to fail to grow or die.
What about animals?
Although they are slightly different, some principles are the same.
"Because no matter whether it is deep or shallow, the eggs will not be able to hatch."
"Is it because the humidity is more suitable in the tidal flats? If it is too dry, it lacks water, and if it is too wet, it will not hatch."
"Is it possible that the winter is too cold and the eggs hatch after the weather warms up? It just so happens that the hen hatches the eggs because the hens stay inside, so the eggs are warm, right?"
…
Compared with others, Yao Jiuye has read the special "Insect Observation Diary" and has a much deeper understanding of locusts than everyone else.
The living environment of locusts and the conditions required for reproduction cannot be clearer.
Yao Jiuye said with bright eyes: "It's just like interrupting a hen when it's hatching an egg. It's cold and hot, cold and hot alternately. The eggs will soon turn into dead eggs and no chicks will hatch. Locust eggs
Likewise, as long as we destroy its incubation environment, locust eggs will not be able to hatch."
"Even if we can't destroy them all, even if we only destroy part of them, it will still be a great achievement." The twenty-second prince Li Zheng saw hope and said happily, "Locusts cause disasters because there are so many of them.
So we have already solved some of them when they hatched, which is definitely a great achievement."
"Even if some of them hatch out, if there is no food suitable for them to eat, a lot of them will starve to death. Even if they don't starve to death, just starve them to thin so that they don't have the strength to fly that far."
…
For the rest, someone took over without Gu Qingling's guidance.
"When locusts were eggs, we destroyed their incubation environment. When they hatched, they had nothing to eat. When they grew older, they encountered a large number of natural enemies... I don't believe it. If we do this, they can still become adults."
Disaster?"
"It's definitely not going to work. It's a chain of links. Unless they are very hard-working, they won't be able to live forever. The survival of the fittest in the animal world is very cruel."
"Then let's discuss now what we can do in each link."
…
Immediately afterwards, they began to fill in their own "locust eradication plan" on the board.
The first stage is to destroy the growth environment of locust eggs.
Although it is not 100% certain, judging from the effects of temperature, humidity, etc. on the growth conditions of animals and plants, they can destroy the original geographical specialness of the tidal flats by plowing the land and converting the tidal flats into ponds, thereby destroying the locust hatching environment.
the goal of.
The second stage is the successful hatching stage of locusts (from larvae to adults).
As mentioned earlier, locusts cannot grow without food. When they are small and cannot fly that far, you can reduce the types of plants they can eat nearby and plant plants they do not eat.
According to the currently known research results, locusts do not eat soybeans, alfalfa, fruit trees and other forest trees. These are the ranges that can be referenced.
The third stage is the stage when locusts grow smoothly (before becoming a locust plague).
The locusts have grown up and can fly, but they still cannot fly very far. At this time, you can use the locusts' natural enemies, frogs, birds and other animals to eliminate them.
Among them, chickens and ducks are within the controllable range, which can encourage large-scale breeding in areas where locusts originate and are prone to outbreaks.
…
The board was filled up bit by bit, gradually taking on what it should have been.
Gu Qingling looked at the board, then at the others who were discussing seriously, with a smile on her face.
Gu Qingling naturally knew how terrible the locust plague was.
In the memory of the original owner, she had experienced such a dark time, but she looked like a lady from a wealthy family, and she had only "heard about it" rather than witnessed it with her own eyes.
The original owner also donated items in order to help the victims, and also prayed to God, hoping that the disaster would pass quickly...
It's not that people in this era don't want to solve the problem of locust plague, it's just that they haven't found a way yet.
Gu Qingling has memories from her previous life, and she knows how her country prevents locust plagues.
There are various methods from biological control, agricultural control to chemical control.
She wants to bring those advanced ideas and scientific concepts to the world.
But she also knows that her own strength is weak and she cannot solve all problems.
At the same time, she also needs to find a reasonable "source" for these things.
Books became her best choice.
Therefore, she trained a large number of book editors, established a bookshop of her own, her own bookstore... directly creating a complete upstream and downstream industry chain.
She needs to completely control this industrial chain in her own hands, so that she can export what she wants.
Among them, "Insect Observation Diary" and "Agricultural Strange Stories" are one of them.
Now, part of the knowledge Yao Jiuye and the princes and grandchildren have learned about insects, especially the various knowledge points about locusts, were provided by Gu Qingling, and some were compiled by Gu Qingling, and agronomists recorded them through observation
, obtained experimentally.
She knew that after these books hit the market, they would definitely not be as popular among readers as the Four Books, Five Classics, and biographies of famous people.
Maybe it was mixed with some third-rate books and became a "miscellaneous book" in everyone's hands.
But so what?
Even if the content in the book seems boring, weird, and not worth reading, Gu Qingling believes that the world is so big, there will always be one or two people who will notice the content and find ways to verify it and read what it says.
is not true.
As long as someone wants to seek verification, then...
Is she still worried that they can't find the locust plague prevention and control office?
She didn't directly tell them how to prevent and control the locust plague, but look, aren't some people already starting to "organize" it?
But what Gu Qingling didn't expect was that the people taking the lead would be Yao Jiuye, the twenty-second prince Li Zheng, the grandson Li An and others.
It's a bit unexpected, but also seems...reasonable.
Who else in the world has thoughts and ideas that are as close to their own as they do, and who are more accepting of the contents of these books?
It took several days before Yao Jiuye and the others finally finished the board.
After they found it, they themselves found it a bit incredible.
They didn't know whether the content they compiled was correct, or whether the "locust extermination plan" they compiled was feasible. But they thought that since they had compiled it, they would publish it in the newspaper and let everyone in the world discuss it.
There are so many smart people in the world, but they don’t believe it, and they can’t solve a small locust plague?
