If you want to "burn the locusts", you must light a bonfire when it gets dark. In addition to the bonfire, you must also set up lights on the roads according to the flight routes of the locusts. Use lights and fire to attract large numbers of locusts along the routes. Then.

The locusts that are burned by the fire will naturally be removed, while those whose wings are burned by the flames will also lose their ability to fly and naturally cannot continue to fly forward, so they can take the opportunity to hunt and kill the killed locusts.

Buried together in trenches.

During the Kaiyuan period of the Tang Dynasty, faced with the great locust plague sweeping across the Central Plains, the Tang Dynasty Prime Minister Yao Chong eliminated the interference of the so-called "disaster from heaven" and used bonfires to kill the locusts, thereby eliminating the locust plague. In the Song Dynasty, when agricultural technology was more developed

, large-scale locust extermination and burning are often used. Burning out locust breeding grounds and plowing them not only eliminates potential disasters, but also obtains a certain amount of fertilizer to replenish the field capacity. It can be said that it kills multiple birds with one stone.

As for the "land strategy", it is actually recorded in the book "Lunheng" written by Wang Chong in the early Eastern Han Dynasty. This method is to use locusts to fly and stop in the area where the locusts will pass.

It is the habit of digging a large number of large pits two feet deep and wide, and then after the locusts arrive, they are introduced into the pits by swatting and other methods, and then they concentrate their efforts on filling them. This method can catch a lot of locusts, compared to

It is naturally more efficient than manual swatting, but the disadvantage is that if the pit is too shallow, the locusts will easily get out and eat crops and seedlings again if they are not suffocated to death.

So Fei Qian simply changed the standard to three feet, and then required that the landfill should be compacted with rocks...

The final "people's strategy" is even simpler: settling the scores and eradicating the roots.

Locusts fly, eat, mate and lay eggs all the way. Therefore, all areas where locusts stay and pass must be burned in winter and then plowed. Naturally, a large part of the locust eggs can be removed, that is,

This reduces the risk of subsequent disasters in the coming year.

Therefore, although the three strategies of "Heaven, Earth and Man" are talked about on the surface, it is actually a relatively complete strategy to eliminate locusts. It just borrows the so-called concept of favorable time, place and people to make it look a bit lofty.

What?

Chickens and ducks get rid of locusts? Or do people eat locusts directly?

Later, the Institute of Zoology of the Chinese Academy of Sciences discovered that locusts have a defense mechanism against natural enemies. That is, most of the scattered locusts are fine to catch and eat. However, once the locusts gather together, they are easily attacked by natural enemies such as birds because the group target is too large.

, so locusts will secrete phenylacetonitrile to release an unpleasant smell to make natural enemies retreat. If these predators do not retreat, the locust community will turn phenylacetonitrile into HCN through a series of reactions, which is harmful to

, which is hydrocyanic acid...

As for hydrocyanic acid...

Haha, I can only say that Li Shimin has a long life, or is it a locust? The dose is still too small. If he takes more, um, I don’t know what will happen to Li Shimin...

Even if chickens and ducks can resist the toxicity of locusts and can eat locusts, how many chickens and ducks are needed to extinguish the locust plague? How can we achieve this in a short time, let alone the human and material resources to collect chickens and ducks, even if we collect chickens from all over the country?

The ducks were all caught in one place, but after hundreds of chickens and ducks were gathered together, the risk of chicken plague, duck plague, and avian influenza increased sharply. This was a huge problem that would not be avoided by modern and constantly spraying farms in later generations. Then if in

The ancient times burst out, so sour and refreshing...

So those who want to use chickens and ducks to kill locusts should go to bed first.

After Fei Qian's packaging, the seemingly ordinary method of killing locusts became mysterious and classic. As orders were issued one after another, Ma Yan, Mayue, and Cai Yan were responsible for the specific deployment of soldiers and civilians. Cai Yan, Wang Chun, and Yuying acted as mascots.

, the vigorous locust extermination campaign in Guanzhong began.

In fact, if you put aside the inexplicable fear of locusts, this thing is actually vegetarian, does not hurt people at all, and is more docile than rabbits. After all, rabbits bite people when they are anxious, and locusts slap them down without even a little resistance.

None, so after the soldiers and civilians in Guanzhong put aside the fear in their hearts, and with the support of the Han hussar general Fei Qian's "Heaven, Earth and Man" three strategies, it seemed that they were becoming more and more powerful in dealing with the locusts.

After all, isn't it just to show some strength? The soldiers and civilians in this area, especially the people who plant crops in the area, even if they are extremely tired, sit down to eat and drink, take a short rest, and then return to the battle against the locusts.

middle.

How could the crops in our own fields, which we had only worked so hard for a year, be eaten by insects in vain?

Many people did not dare to be cruel to the gods, nor did they dare to challenge Fei Qian and others, but these people were cruel to themselves. They did not need any repeated orders at all, and almost risked their lives to cull the locusts. They dug holes and swarmed them manually during the day.
