Three Kingdoms, at the beginning of the game, recognize the thief as the father, hit the spectacle,

There is also a relatively simple reason. As for why Zhang Yan chose officials from the Department of Public Security as the main force to exterminate locusts, it is because these people are the faction with the largest number of members in the entire Lujiang official system, and they are also the faction that is most familiar with the landscape of Lujiang.

Under such circumstances, if Zhang Yan didn't choose these people, who would he choose when he went back?

……

All in all, after shifting his attention from the Department of Agriculture to the Department of Public Security, Zhang Yan looked at the attitudes of the two local leaders and saw that they were quite upright, so he nodded secretly and didn't say anything besides the topic.

But obviously, exterminating locusts is not something that can be explained clearly in a few sentences.He couldn't just say that he regarded the locust army as an invading enemy, so he really wanted the guards in charge of security to charge up with swords and spears to chop and stab the locusts, right?

After slightly lowering his head and thinking for a moment, Zhang Yan's eyes lit up, and then he raised his head to look at the people present.

……

"Regarding the Department of Public Security, the most important thing is to directly kill the locusts."

"Whether it's direct culling, setting up baits to gather traps or something else, as long as it can kill locusts on a large scale, I can allow it."

"Of course, once the locusts swarm, it is not easy to kill them on a large scale, and you may even be in danger because of this... If you have no ideas, I can also give you some small suggestions."

……

PS: Recently, I saw many readers telling me that chickens and ducks cannot kill locusts, they are poisonous and so on...

In fact, the author really wants to say, I am a graduate of Xiamafang Royal Agricultural University, Department of Biology, how could I make such a mistake...

I'm not the kind of person who casually writes historical novels to make quick money...

Otherwise, I will go to colonize the New World at the beginning.That is more topical.

It’s just that many people have been mentioning it recently, so let’s talk about it after thinking about it...

Chickens and ducks don't eat poisonous locusts because they feel like they will die.

But locusts need five weeks to turn into adults, adults can fly, and adults can be poisonous.

In addition, chickens and ducks generally do not eat adult insects, and rarely eat non-toxic ones, because they are too hard to swallow, and frogs and toads like to eat adult locusts.

Chapter 11 morning

Yes, just like what Zhang Yan just said, it is actually not very easy to directly kill large-scale locusts.

On the one hand, what can evolve from a swarm of locusts into a "plague of locusts" is because there are millions or even tens of millions of terrifying numbers. When these locusts gather together, they can even cover the sky and block out the sun, making all beasts retreat.

Different from ordinary locusts, in this case, the locust has completed the change called "zombification", the whole body has become dark, and it is even extremely aggressive, and it is easy to bite people's skin , and even killed younger children directly.

On the other hand, anyone who has experience in locust extermination knows that it is not difficult to catch and kill locusts, but it is not easy to kill grasshoppers...

Different from those annual insects, locusts are also known as "hundred-day insects". Even if the egg stage is counted, their lifespan rarely exceeds a hundred days.

The locusts that are common and easy to see in the Huaxia region are East Asian migratory locusts. These guys take two to three months as a cycle and can reproduce three or even four times in a year. It is almost difficult to kill them directly with conventional physical means. .

……

To give the simplest example, if there are about 200 million individual locusts in this locust plague, then Zhang Yan will probably kill 500 million locusts by organizing people to trap and kill them. Completely eradicate the locust plague.

This is because while people are hunting and killing, locusts are constantly laying eggs every day and night. After ten or so days, new locusts will break out of the ground and once again form groups to sweep the earth.

This situation is incomprehensible and even unacceptable to almost all feudal dynasties...

It was as if those locusts were God's punishment. If one batch was killed, there would be another batch. They could only survive until the winter of that year, when the locust eggs no longer hatched, and all the hatched locusts froze to death, so that the people could get a little respite.

But in the face of this kind of difficulty, the ancestors of Huaxia are not helpless...

If the previous act of snatching all the food in advance was to erect walls and clear the fields to consume the enemy army, then the next step is to encircle and kill the existing enemy army.

This was not until the Ming and Qing Dynasties more than 1000 years later, after thousands of years of struggle, the people in the Huaxia region finally summed up a set of methods to deal with the locust plague.

It was also from that time that the national regime was not as helpless as its ancestors were in the face of locust plagues.

……

"If I remember correctly, things like locusts can't live for a hundred days. It's just that every night, they will mate and lay eggs, resulting in a steady stream of new locusts hatching and joining the swarm of locust plagues."

"Newborn locusts are different from adults... If you have paid attention, you will find that small locusts cannot fly, their body color is lighter, and their wings are not fully developed."

"As the age of the locust increases, this small thing will molt five times in total, and each time it molts, it will be closer to the 'complete' form than before."

"Suppose we call the locusts that have completed five transformations and can enter the zombified state adults, and the locusts that have not completely transformed into adults become 'nymphs' that look like adults..."

"The locusts in the nymph stage are almost completely non-toxic. Even if chickens and ducks eat a lot, they will not experience any discomfort. In addition to eating, the biggest physiological impulse of the locusts in the adult state is to reproduce, so it can provide temperature and light. The fire is very attractive to them at night."

"As long as we make good use of the habits of these locusts, we are not completely helpless."

……

A set of locust extermination methods that can be said to be completely aimed at the physiological habits of locusts was handed over by Zhang Yan to the security officers who were temporarily transferred by him to prepare for the locust extermination work.

And Zhang Yan himself didn't realize at all that the set of methods he said just now would have a great impact on the somewhat "traditional" or old-fashioned agricultural system of the Eastern Han Dynasty.

Even though there is no shortage of food in Lujiang now, even many ordinary people can eat some meat every now and then... But this does not mean that the production efficiency of Lujiang is as high as that of the Ming and Qing Dynasties in later generations.

If we insist, this kind of "richness" is bestowed by Lujiang's unique geographical environment.If we only talk about the output per mu of land, there is not much difference between Lujiang today and other places in the Eastern Han Dynasty.

In the past, Zhang Yan initially standardized the retting and production of farmyard manure. The direct solution was not the maximum amount of grain that a piece of land could produce, but the problem of spending a lot of time on cultivating the field after every grain cultivation. .

Assuming that Lujiang is compared with the counties next to it, such as Danyang, the total cultivated land area of ​​Lujiang will not be much larger than that of Danyang, but the land that can be used for planting in Danyang is only half or even a third of that of Lujiang. First, this is the fundamental reason why Lujiang is now able to achieve food self-sufficiency, or even complete surplus.

The skill is not enough, the quantity comes together.

If we really want to talk about how to cultivate the land, the current Lujiang... is still far behind.

At least we have to wait for human farming to evolve into full-scale cattle farming, right?

……

Briefly explained the principle of locust extermination to several persons in charge present. Similarly, the person in charge of the physical locust extermination work was also put on Kuai Qi's head by Zhang Yan.

As the saying goes, those who can do more work, whether it is Zhang Yan or Kuai Qi, they still remember that when they were in Luoyang, Zhang Yan made a promise to him:

The position of Prime Minister of Wancheng is just the beginning. If Kuai Qi's experience and ability have been fully developed, it is not impossible to recommend him to further climb up, and even take up such an important position as the prefect.

And if he wants to be promoted as soon as possible, proper overtime work and cross-departmental work will naturally become things that Kuai Qi must complete.

……

"Then, this matter will still be supervised by Kuai Qi. When it is actually implemented, all the public security departments and public security bureaus in various places will be dispatched to light live dogs at night to trap and kill adult poisonous locusts."

"When the adult locusts are almost killed, the Department of Agriculture will free-range a large number of chickens and ducks near the locust colonies, and let these chickens and ducks help eliminate the hatched nymphs... The nymphs can't fly, so they can be used as rations to help Adding fat to chickens and ducks will alleviate the food pressure in this autumn and winter in disguise."

……

The work that each department needs to be responsible for was arranged, and soon, one by one, the handbooks were distributed around Zhang Yan, and the officials who were mainly responsible also said goodbye to Zhang Yan, and went home overnight to start their own business small meeting.

After the moon was in the middle of the sky and the drums outside the door rang three times, Zhang Yan suddenly came to his senses. Since when, only left him alone.

"Phew... Do your best and obey the destiny. If I do this, it can be regarded as my best? If Lujiang can't survive this disaster, then I have nothing to do..."

Standing up tremblingly, Zhang Yan's knees were even slightly numb because of sitting on his knees for too long, making him unable to stand upright.

And now it's very late, and those waiters and the like have gone back to rest, so naturally no one will rush over to help him.

In this way, Zhang Yan limped into the courtyard, looked at the extinguished boiler not far away, and the remaining fire in the boiler, and felt a long-lost tiredness from his heart.

……

"yawn--"

"I don't know what time it is now, the second watch or the third watch? It seems that the third watch has passed the time just now... I didn't notice much."

……

After moving around in the yard for a while, Zhang Yan looked at the moon that was about to rise above his head, and then at the quiet surroundings. After thinking for a while, he walked back to the previous room.

"Forget it, it's already this time, so I won't go back and disturb their rest. The time to go back and forth is not enough..."

"These days are probably enough for Kuai Qi and the others to be busy, so why not just sleep in this room...Anyway, it's summer, and it won't be cold without a bedding."

A gust of night wind blew past, Zhang Yan shivered suddenly, then tremblingly walked back to the room, closed the door tightly, put on a robe, and found a corner to lie down.

It may be because Zhang Yan just took a bath this afternoon, Zhang Yan's brain felt hot and dizzy for a while.

Not long after, he fell asleep in a daze.

……

"Well, the floor is so hard... When I have a chance in the future, I must have someone lay a mattress or something in these places I often go to, so that I can rest conveniently..."

"I knew it earlier, so I went to sleep next door. There is a bed there anyway, even if it is a bit damp, it is better than sleeping in this kind of place... There is not even a pillow."

"My neck hurts."

……

Half asleep and half awake, the unfamiliar environment and the gradually dropping temperature at night made Zhang Yan sleep very uneasy.

Coupled with his height of about 1.7 meters, he is already very tall in this era.His overly broad shoulders made him feel a little uncomfortable in his neck without a pillow.

"Hmm... Kurusi..."

He didn't know what he was mumbling about, just like that, Zhang Yan turned over several times in a daze, and finally fell asleep.

And in his sleep, he seemed to feel a figure quietly walking beside him, but before he could wake up, a familiar feeling made his whole body relax.

"Look at you, you don't know how to cherish yourself..."

……

……

……

The night passed quickly like this, and when the first ray of sunlight entered the room the next morning, Zhang Yan woke up on time.

During the two years since entering the Eastern Han Dynasty, Zhang Yan didn't learn anything else because he didn't have mobile phones, computers, and the Internet to kill time at night. The habit of going to bed early and getting up early was well developed.

As long as he didn't fight too long the night before, or something happened that forced him to stay up all night, Zhang Yan would basically wake up around Mao time the next day, hundreds of days like a day.

And this time was no exception, the moment Zhang Yan felt the sun shining on his face, Zhang Yan frowned, then turned over slightly, and buried his face in the softness below.

……

"Well, eyes... my eyes!"

"Ying'er, what time is it? Pull the curtains for me, it's so dazzling..."
