What Du Ruhui said was also what many ministers thought.
The terrible locusts have always been considered as a punishment from heaven.
Who would associate it with the grasshoppers that can be seen everywhere on the lawn?
If Xu Fenglei hadn't revealed its origins, Kong Yingda's statement would probably have dominated the mainstream forever!
"In fact, to create a terrible locust plague, three conditions need to be met at the same time: time, place, and people!"
Xu Fenglei turned the meeting into his own popular science lecture hall and said loudly,
"When the weather is right, it's drought!"
"Locusts love heat. In the hot summer, they are extremely happy and can fly up and down unscrupulously and gather in swarms!"
"The favorable location is an environment for locusts to breed!"
"In a hot and rainless environment, the river bed is exposed, and that part of the moist soil is exposed, which is a good place for locusts to lay their eggs. In addition, this winter is a warm winter, and there is no snowfall to freeze the eggs in the soil. The combination of the two This caused a large number of locusts to breed!"
"As for human beings, this is because during the dry season, vegetation is concentrated in places with abundant water flow, such as streams and lakesides. This creates conditions for grasshoppers to breed and grow intensively."
The ministers listened with rapt attention.
Li Shimin also listened extremely seriously, like a good student.
The knowledge Xu Fenglei mentioned was something they had never heard of before and could never find in ancient books!
The doctor in the corner of Liangyi Hall wrote quickly and recorded Xu Fenglei's words verbatim.
These words are a precious treasure for the Tang Dynasty and for future generations!
"Then the question is, if grasshoppers gather together on a large scale, squeezing and rubbing each other, what will they look like?"
Xu Fenglei held up the restless grasshopper in his hand, pointed at it and said,
"Here, look!"
"It will become like this, it is evolving in the direction of locusts!"
"Once they complete the evolution from grasshoppers to locusts, they will transform from solitary insects to social insects, and their former natural enemies, such as frogs, pheasants, wild ducks, egrets, etc., can no longer attack them!"
"This is how the locust plague began."
"Do you understand everything?"
After saying that, he subconsciously went to find a water glass to drink from. After searching around and failing to find it, he suddenly realized——
He is not teaching in the East Palace, but attending court in the Liangyi Palace.
"Young Master, here it is."
The eunuch on the side quickly brought a cup of tea and said respectfully,
"Your Majesty will give you a cup of tea."
Xu Fenglei raised his eyebrows and looked up at Li Shimin.
At this moment, Li Shimin was also turning his gaze towards him, his expression full of approval.
Snapped! Snapped! Snapped!
"Okay, okay, okay!"
Li Er applauded and praised,
"Young Master is worthy of being a Young Master, he is indeed well-informed!"
"In my opinion, you are the only one who can bear the word 'doctor'! You are knowledgeable and knowledgeable!"
Gudong, Gudong.
Xu Fenglei drank the tea in one gulp, cupped his hands and said:
"Your Majesty is so complimentary."
"I'm just good at observing and likes to think."
"There are countless things under the sun. We all know them but don't know why. This is nothing in itself. We just need to actively explore them."
"But if you don't use your brain or your heart, you classify it as metaphysics, lead it into strange stories, or even blame one person for all kinds of disasters... I really can't agree with it."
Kong Yingda's face turned red and he looked a little embarrassed.
As soon as Xu Fenglei's science popularization came out, his "theory of induction of heaven and man" was buried in the soil and swept into the garbage heap.
Although I feel a little unhappy, I can’t refute it...
"well said!"
Li Shimin agreed,
"Everything in heaven and earth has its own reason!"
"Observe it, observe it, and think about it with your heart, and you may be able to understand the principle."
"Just like this locust, it must have been through patient observation and repeated thinking by the young master that it completely revealed its original shape!"
"Deserves a commendation!"
"Come here, give me five hundred pieces of silk, and send them to Duke Xu's house immediately!"
"According to the order."
The eunuch beside him took the order and left.
"Thank you for your kindness, Your Majesty."
Xu Fenglei bowed his hands.
Li Shimin smiled, held his hand and said:
"Listen, since these locusts are grasshoppers, do you know how to control them?"
He is in a good mood now. At least the blame for the locust plague can no longer be blamed on Li Er!
However, Xu Fenglei shook his head.
"It's not easy to govern."
He said in a deep voice,
"Locust disasters can be prevented, but difficult to control."
"At the beginning of the new year, I told Your Majesty that there will be no snow this year, and there may be drought and locust plagues."
"The two often come together to wreak havoc on crops."
"If we want to prevent it, we cannot control the weather. We can only start from the right location, people and people, and kill it in the cradle before it forms!"
Li Shimin's smile faded and his face darkened.
"For example, poultry are raised and allowed to walk among fields to look for insect eggs and eat them."
Xu Fenglei listed:
"Another example is cultivation. To protect the natural enemies of locusts, we order the people not to hunt wild frogs, orioles, lizards and other creatures. As long as they are allowed to form a certain scale in the wild, the reproduction of locusts can be suppressed."
"In addition, according to the biological habits of locusts, more trees can be planted in low areas of the terrain to destroy their habitats."
"These multi-pronged methods can prevent the locusts from becoming a climate change even if they cannot be completely eliminated. A few scattered grasshoppers are really just grasshoppers and will never turn into locusts and harm the world!"
Li Shimin nodded repeatedly.
"Write it down, write it all down!"
He hurriedly ordered,
"Your Majesty, everything has been recorded, every word has been missed."
The scholar on the side held his pen confidently and said seriously.
"Okay, if we control locusts in another year, we will follow the Young Master's strategy. All these points must be implemented in place!"
Li Shimin said solemnly,
"I hope the world will never be invaded by locust plague again!"
"Your Majesty is wise." All the ministers sang in unison.
"Listen clearly, you just said that controlling locusts is about prevention and not control, but now this situation..."
Li Shimin looked at Xu Fenglei again and said earnestly,
"Can't you even do anything?"
No matter how good the locust control strategy is, it still belongs to the future.
The locust plague currently raging is an urgent need!
If this problem is not solved, there will be a large number of disaster victims in Guanzhong!
"Return to Your Majesty."
Xu Fenglei said helplessly,
"The locust plague has become a climate, and I don't have a good strategy in mind at the moment."
"Perhaps your colleagues can have some insights?"
He pointed to the ministers behind him.
Li Shimin followed his finger and looked at Fang Xuanling, Wei Zheng and others.
"My dear friends, do you have any solution?"
Li Shimin said sadly,
"I can't just watch my people in the Tang Dynasty become victims of a locust plague!"
"If anyone can give you an effective method, I would like to express my gratitude as the emperor!"
