Since ancient times, Kaifeng has been a "mouse city".
Kangxi once ordered the city to be burned to eliminate the rats, but the local people still had no way to eliminate the rats, so in the end Dou Tianyi had to come to alchemy and set the rats on fire.
It can be seen that the number of rats at that time is still unbelievable.
As an ancient enemy of human beings, rats not only eat crops and gnaw stored grain, but also pose a great threat to agriculture, forestry, animal husbandry and industry, bringing a series of disasters.
In recent years, many people say that there are fewer and fewer mice, and even rats are gradually gone, so what is the reason why rats choose to retire?
1. The harm of rats.
As pests, rats can be found in almost every corner of the world, and because they grow extremely fast, their numbers are also very large.
But when the number of rats is too large, it will pose a threat to people's production and life, which will not only endanger people's lives, but also affect people's production process.
As we all know, rats are omnivorous animals, they will not only eat people's food, but also bite people's various utensils, so rats are also known as "rat pests".
Rats not only bring direct material losses, but also spread a variety of infectious viruses, and can also cause a series of disasters such as fires.
Rats often live with people, so they can easily spread diseases.
Rats will not only through urine, feces, but also through hair, saliva and other ways to stick the particles of bacteria to various utensils in people's lives, when people come into contact with impurities on these utensils, it will cause the spread of certain diseases.
So rats are able to transmit a wide range of diseases, not only the common flu, but also the uncommon diseases of bacilli, typhoid and brucellosis.
To make matters worse, rats can also transmit a variety of viruses through parasites on their bodies, many of which are very virulent viruses, such as plague.
Plague is caused by Yersinia pestis, and rats are the transmitters of plague, as long as rats have Yersinia pestisis in their bodies, they will spread Yersinia pestis to people through fleas on their bodies, posing a threat to people's lives.
In many countries and regions in the world, many people have died due to the emergence of plague, and it can be said that plague is a very deadly disease and a major hidden danger in people's lives.
Second, the harm of rats to agriculture and forestry.
In addition to spreading diseases, rats can also cause harm to crops, because rats are omnivores, so they will constantly look for food, so they will continue to reproduce.
When the number of rats increases, so does the amount of food they eat, so it can cause harm to people's crops.
When rats eat crops, they will not only destroy the form of crops, but also eat the fruits of crops, so a large part of crops will not be harvested normally, and when rats gnaw on the leaves of crops, they will also bite crops into pieces, causing the death of crops.
The crops that rats like to eat most are corn, wheat, soybeans and other crops, which are the main food crops of people, but when rats eat these food crops, it will have a great impact on people's lives.
Crop losses caused by rats are very painful all over the mainland, especially in the Yunnan-Guizhou Plateau, where people grow corn and other crops that are tropical, so they are vulnerable to rat infestation.
In the farmland of Henan Province on the mainland, there are many underground warehouses, which are not only used to store grain, but also places for people's lives.
The rats like to infest people's grain storage warehouses the most, so they will continue to infestation the underground warehouse, resulting in the loss of stored grain, and rats are good at drilling holes, so under their infestation, people's large amount of food will be destroyed.
At the same time, the rats also eat seeds and seedlings, and the seedlings, as well as the young trees of the fruit trees, are their delicacies in the eyes of the mice, so they will also eat the seedlings, and when the rats finish eating the seedlings, the seedlings will die.
In addition, when rats eat the young trees of fruit trees, the fruit trees will not grow normally, or even produce normal fruits, so it will also affect the harvest of fruit trees.
3. Harm of rats to forestry and animal husbandry.
Rats can also cause a lot of damage to the forestry industry because rats eat a lot of food, so when there are too many rats, they can cause a lot of damage to the trees in the forest.
Especially in the northeast of the mainland, the forest resources here are relatively rich, so it is easy to become a "delicacy" for mice, rats will not only eat the bark, but also eat leaves, but also gnaw on the branches, so it will cause great damage to forest resources.
When rats eat the bark and branches of trees, these trees will die, and in the process of rats, they will bite the trees into pieces, so it will also cause the trees to not recover, which will cause great loss of forest resources.
In addition, rats will also eat pasture, so they are also a major hazard of animal husbandry, especially in the grassland areas of the mainland, where forage resources are relatively abundant, so it is easy to become a "delicacy" for mice.
When the rat eats the grass, the grass will die, and in the process of the rat's gnawing, the grass will be gnawed into pieces, so it will also cause the grass to be unable to recover, which will cause great loss of forage resources, and will also have a great impact on the life of livestock.
Fourth, the harm of rats to industry and construction.
The corpses of rats will decompose as a result, so they will release a large amount of ammonia gas, and will also emit toxic gases such as odors, which can pose a threat to people's lives.
At the same time, rats will also pose a great threat to power equipment, because rats will bite power lines, so once a rat enters the power plant, it will have an impact on the power and even cause accidents such as fires.
Therefore, rats will also have a great impact on industry and construction, so people's production and life will be threatened, and after years of control, the number of rats has gradually decreased.
5. The reason for the decrease in rats.
The decline in the number of rats may be closely related to human activities, especially in the mainland, where the area of farmland and woodland is shrinking, and at the same time, rocky deserts and ditches will be reconstructed, which will also have an impact on the habitat of rats.
As the number of rats is getting smaller and smaller, the competition between rats will also increase, which will also have an impact on the reproduction of mice, and in addition, people's awareness of environmental protection is gradually increasing, so it will also have an impact on the reproduction of mice.
At the same time, rats, as pests, cause great inconvenience to people's production and life, so people have a certain degree of control over mice, but the decrease in the number of rats will also have an impact on the ecological balance.
Because rats are omnivores, they are constantly looking for food, and when the number of rats decreases, it will lead to a decrease in their food chain, so the food of rats will become more diverse, which will have an impact on the number of other animals.
Therefore, when the number of rats decreases, it will affect the number of other animals, which will lead to the excessive number of other animals, so it will threaten people's production and life.
Therefore, when people control the number of rats, they need to formulate some reasonable control measures, not only to control the number of rats, but also to protect the ecological environment, and the progress of science and technology also has an impact on the number of mice.
epilogue
In the future development process, science and technology will gradually progress, so when using technology to control the number of rats, we should also pay attention to the protection of the ecological environment, which is also an aspect that we need to pay attention to in the future.
