"Sir, what is the best way to get rid of the locusts?"

Zhao Jia introduced Zheng Guo into the inner room and asked with a little worry.

In Zhao Jia's impression, Zheng Guo was just a person who was good at building water conservancy, and he had never heard of him exterminating locusts.

Zheng Guo took out three documents from his arms and solemnly handed them to Zhao Jia.

"Please take a look!"

Zhao Jia took the document and found that it was densely packed with small characters, and the length was not small.

"Wait and see."

Zhao Jia was eager, sat down and began to read the content, and his heart changed from curiosity and eagerness at the beginning to shock and admiration.

The first sparse is written: The state does not accumulate livestock, does not prepare for hunger, and this personnel is also a loss.

There are three causes of hunger: water, drought, and locusts.

The land is humble, the rain is biased, it is plagued by floods and droughts, and there are still many places that have been spared, but the drought is extremely locust, and the grass and trees are all exhausted for thousands of miles, or the cattle and horses are all gone, and the harm is especially worse than the water and drought.

Although the two disasters of flood and drought are heavy and light, and they want to be constant, although Tang Yao's life is still not possible, it is set by heaven.

However, if the locusts are not, they should be repaired first, and they will be rescued after they have been repaired, and there will be no remnants of manpower that can be destroyed. This is different from water and drought.

Water gets a hill and a hill, and drought gets a well and a pool, that is, a single cold solitary son talks enough to save himself.

However, the locusts will rely on the merits of the state, the concerted efforts of the people, and the unity of tens of millions of people.

In short, the plague of locusts is very serious, and it is easy to get rid of it, and we must work together to eliminate it.

Just the first sparse showed Zheng Guo's outstanding insight.

Compared with the superstitious ancients of this era, they have regarded the locust plague as a natural disaster, believing that natural disasters cannot be resisted, and only by sacrificing to the heavens can the disaster be eliminated, Zheng Guo is very sure that it will be a human disaster.

Why?

Floods and droughts are natural disasters that people can't change, but locusts can be hunted and killed, and as long as they are killed, the harvest will not be affected.

On the other hand, if you sit back and watch the locusts eat all the seedlings and dare not hunt them, what is this not a man-made disaster?

Not only that, Zheng Guo also pointed out the root cause of the outbreak of the locust plague -- the drought is extremely brilliant, and even more boldly pointed out that the locust plague is more terrible than the flood and drought disaster.

Floods can be blocked by mounds and rocks, and can be stored in depressions and lakes; Droughts can be irrigated with water from wells and rivers, and even the poorly clothed people can be alleviated as long as they work hard.

Only the locust plague is the most terrible, and it cannot be eliminated by one person, one family, one county, or even one county, because locusts are alive, can migrate, and can give birth.

Even if a farmer tries to kill all the locusts in his field, if the rest of the farmers do not kill the locusts in the field, the locusts in those fields will run to the fields where the locust farmers are hunting.

Therefore, it must be destroyed by the merit of the state, by the cooperation of the group, and by the concerted efforts of tens of millions of people.

When Zhao Jia saw this, his heart couldn't help but pound, and he hurriedly began to look at the second sparse.

Where locusts are born, they will be at the end of Daze, but where there are many rains and rivers, there are no locusts in ancient times, so the locusts will be where they suddenly dry up.

The lake is widespread, the narrow is impermanent, it is said to be dry, and the locusts are born.

From this the locusts shall be the land of the locusts.

Therefore, those who dry up are the origin of locusts, and they want to get rid of locusts.

(Note: lake, lake swamp; Wide, vast, empty, low, flat land. ）

I inspected all sides, next to Daze, in the land of reeds, born of reeds, and on the banks of the water, I saw many locust eggs, so it is speculated that locusts are water species.

Or that the locust is made of caviar, and I think that the locust is a sickle (a land animal parasitic in the water).

Where insects, insects and feather insects can be phase transformed, such as moths for moths, beetles for cicadas, and maggots for mosquitoes.

If the scale insect can become a heterogeneous species, it is not seen, this is also a proof.

The sickle is good at swimming and jumping, and the worm (the nymph of the locust) is also good at jumping.

Although the phase of things changes, most of them are molting into shells.

If the shape of the locust is cool, its body, its head, its veins, the smell of the flesh, and the shape and taste of its children are nothing but sickles, and these three certificates are also.

The silkworm becomes a moth and a moth, the child becomes a silkworm, the locust becomes a sickle, and the sickle also becomes a locust.

After reading the second sparse, Zhao Jia was extremely shocked.

He never thought that the ancients of this era would have such great wisdom and study locusts so thoroughly, that they could be said to be biological experts.

Although the second Shu only introduces the birth form and location of locusts, it contains Zheng Guo's countless efforts, and also allows Zhao Jia to find a powerful example of eradicating locusts from the source.

Only by eradicating locusts at the source can we truly solve the locust plague, otherwise even if a batch is killed, as long as the drought continues and the weather is suitable for locusts to multiply, there will still be a steady stream of locusts.

Zhao Jia held his breath and continued to look at the third sparse.

There are various kinds of sickles, the white ones with soft shells are scattered at the beginning of summer, and the red ones with strong shells are scattered at the end of summer, so the life of locusts is also different sooner or later.

There is a lot of water in the south of the river and there are no locusts, and the water and grass in the lake are accumulated, and the aquatic grass farmers in the south take more fields to strengthen the fields, which is not the case, and the lake is always full, the grass is always in the water, and the sickle is attached to it and it is just a sickle.

The lake in the north is overflowing, the grass follows the water, it is dry, the grass flows endlessly, the sickle is attached to the grass, neither water, it is steamed in spring and summer, and it becomes a locust by the hot and humid air, and its momentum is also.

Therefore, it is known that locusts are born in sickles, and the sickles are locusts, because of the accumulation of aquatic plants.

If you know the source of locusts, you should get rid of them in their original land.

Wherever there are lakes, depressions, or stagnant water, after frost and precipitation have fallen, officials at all levels should be ordered to inspect the current year's water (water after rain).

There are many aquatic plants and sickles in the water, and the people of the husband invade the water and mow (kill), and they are placed in the high place, and the wind is exposed day by day, and they are dried for the salary.

If it is unusable, burn it on the spot, so as to exhaust it.

This requires the concerted efforts of county officials to be beneficial. If one party is sluggish, it will sprout and the other party.

There is no need to kill the inexhaustible people.

If in the spring and summer months, the inhabitants catch one stone of the sickle in the Po Lake, and reduce the locusts by one hundred stones; One stone of dry sickle, less locusts of a thousand stones. However, the people should be informed of this reason, and they should not bother to warn about it.

The content of the third record made Zhao Jia ecstatic.

Zheng Guo very accurately predicted the growth and development environment and cycle of locusts, so that the sickles could be removed in advance and the outbreak of locusts could be prevented from the root.

The most important thing is that Zheng Guo has analyzed the growth law of locusts so accurately and meticulously, as long as it is published, the people will no longer regard it as a divine insect, and without a sense of awe, in order to protect the food, how can the people not do their best?

The most amazing thing is that Zheng Guo did not simply remove locusts, but artificially created an environment suitable for locusts to lay eggs, and then trapped.

With these three ways of eliminating the sparse sparse, as long as the county officials do their work conscientiously in the future, they can basically put an end to the outbreak of the locust plague.

This simple three-way elimination of locusts is a real good policy for rejuvenating the country!
