When Chen Fan returned to the Zhiqing Point, he found that the four girls were all there today, and the courtyard was different from the excitement of the past.

Huang Ying held a wooden stick in her hand and looked around with a serious face, as if she was looking for some assassin.

Yang Ju was even more ruthless, with tongs in one hand and a firewood knife in the other, and her expression was exactly the same as Huang Ying.

Jiang Lili was carrying a bucket and was pouring water into a hole in the ground, and on the other side, Liu Dan was holding a pile of half-dried weeds, lighting them and smoking them into a hole.

As a result, I didn't get much smoke, but I smoked myself and coughed repeatedly.

Chen Fan turned over and dismounted, put the basket containing the little rabbit on the ground, patted the little mare's back, and let it go back to the stable by itself.

Then he looked at them with puzzled faces, "What are you doing?" ”

Huang Ying immediately rushed over, "Teacher Chen, there are rats in the house." ”

Yang Ju waved tongs and firewood knives, and said, "Such a big one, fortunately, I went to the room to scoop rice, and I happened to see it, otherwise the rice would have been stolen and eaten by mice." ”

Huang Ying said hatefully, "It must be the fish that slipped through the net last time when the rats were caught clean." ”

Jiang Lili knew Chen Fan best, and knew that he didn't understand many things, so she explained in a whisper, "In the winter month, not long before you came here, the brigade organized a team-wide rat hunting operation, putting mouse traps, pouring rat holes with water, putting smoke, and putting rat poison, eliminating more than 2,000 mice.

This kind of rat hunt happens every two or three years, and I've only been here for three years, and I've come across two times. If you don't catch rats, the rats will eat the crops, and after a long time, they may even form a rat plague. ”

Liu Dan held the smoking straw handle and nodded vigorously, "Rats are the first of the four evils, and they are the most hateful." ”

Chen Fan suddenly understood in his heart.

Later generations may be a little unfamiliar with the word rat plague, and there are many other things in this era that are rare after more than 20 years, let alone the new century.

Nowadays, however, rat plagues are common. And anything that is called a "disaster" is not a trivial matter.

Thousands of rats come in swarms, and they are not afraid of cats, dogs, or people. If you are not careful, the crops of the entire brigade or even the entire commune may be destroyed.

In particular, the bacteria and viruses carried by rats can be infected with plague as long as they are bitten or scratched by them, and they must not be careless at all.

For example, smallpox, poliomyelitis, filariasis, schistosomiasis, Keshan disease, osteoarthritis, leprosy, malaria, plague, cholera, etc., in the eyes of young people, almost all of these names only exist in textbooks, and there is no personal experience.

But in this day and age, many diseases and viruses are as commonplace as colds.

The elderly, in particular, many have survived the battle against these diseases and viruses. After decades of struggle, these diseases were sealed in books and a "health war" was won.

As early as 52 years, the campaign to promote cleanliness and eliminate germs began. All parts of the country are sanitizing pests, unclogging underground pipes and sewage channels, cleaning up a large number of garbage mountains and river ditches, and calling on people throughout the country to drink hot water instead of raw water.

The famous "Dragon Whisker Ditch" tells the story of cleaning and rectifying a stinky ditch in BJ at the beginning of the founding of the People's Republic of China.

At that time, the concept of the "four pests" had not yet been proposed, but the main targets of eradication were mosquitoes, flies, lice and rodents, which highly overlapped with the four pests, and the later four pests were also proposed on the basis of this campaign.

The reason why sparrows are among the earliest four pests is that a certain "scientist" proposed that a sparrow can eat as much food as it can eat in a month, half an adult's daily ration, and how much food can 100 million sparrows eat,......。 Such alarmist rhetoric will be listed as one of the four evils.

Later, it turned out that the sparrow's eating of grain did not have much effect on the total amount of food in the country, so it was quickly replaced by bed bugs and cockroaches.

Since then, the campaign to eradicate the four evils has not stopped.

As the first of the four pests and the carrier of plague, rats are the focus of long-term combat.

The Jiangnan region has long been a breeding ground for rats due to its abundant waterways and abundant products.

Lujiawan conducts a rodent extermination campaign every two or three years, which is just the norm for various production teams in the Jiangnan area in this era.

And this great movement, which lasted from the 50s to the early 90s, also successfully sealed many germs and effectively protected the life, health and safety of the whole society.

Retracting his thoughts, Chen Fan looked at the four of them and asked, "Did you find the mouse?" ”

Huang Ying immediately pointed to the two holes in the corner of the courtyard wall, "I found two mouse holes, and they are flooding with water, and when they come out, they can be killed." ”

As she spoke, she swung her stick twice, as if to kill the rat at once.

Chen Fan walked over and took a look, both holes were the size of fists, and they did look like rat holes.

It's just that half of the bucket of water is filled, and there is a lot of smoke on the other side, under normal circumstances, if the rats were still inside, they should have escaped a long time ago, right?

Chen Fan pondered for two seconds, raised his head to look at the sky, and sure enough, the stupid bird followed back, and beckoned to the sky.

The falcon chirped twice and swooped down on him, flapping its wings gently as it landed, resting firmly on his arm.

Chen Fan chirped in his mouth, "Go, see if there are any rats in and around the yard." ”

The falcon immediately flapped its wings and flew up to the roof, turning its head to make its rounds.

Catching birds and mice is the strong point of the falcon, but it is still a little difficult for it to catch a big hare, after all, it is only a small bird of prey, not a large bird of prey like a golden eagle or vulture, and its strength is naturally incomparable. But if the boss has orders, it will try its best to catch it, and if it can't catch the big one, it will catch the smaller one.

Today, it is rare for the boss to catch mice, and it is naturally excited to work hard.

Standing on the roof and looking around, he couldn't find it, and the falcon flew up to the sky to look for it.

Huang Ying saw Chen Fan looking at the falcon and asked strangely, "Teacher, what is it doing?" ”

Chen Fan said without looking back, "Looking for a mouse, you are flooding and smoke attacking, the mouse has not come out, it must have been in the hole for a long time." ”

When the four girls heard him say this, they also felt that it made sense, so they put down their "weapons" in their hands and looked at the falcon together, hoping that it would find the mouse.

It's a pity that although the eyes of the falcon are powerful, it can't find it when the mouse burrows into the hole. After flying two laps, he tweeted like Chen Fan, "No." ”

Chen Fan beckoned, summoned it down, and then said, "Warning again, don't eat mice if you find it, don't touch it, otherwise you won't suffer Lao Tzu in the future." ”

The falcon tilted its head to look at him, "I don't eat mice." ”

It is now addicted to catching rabbits, it will catch a rabbit every day and come back, and when it is hungry, it will look for Chen Fan or Jiang Lili to eat, it has been a long time since it has eaten a bird, let alone a mouse.

Chen Fan didn't care so much about it, but Jiang Lili would change the tricks to prepare for it to eat, sometimes pork or pork liver, sometimes fish or fish offal, let it change its taste, these meats were brought back by the way when Chen Fan was "in class" at the veterinarian station a few days ago, Jiang Lili got some meat foam to give favors.

Once Jiang Lili wanted to feed it cooked meat, but she heard Chen Fan say that wild birds were not good at eating cooked meat, so she regretted giving up.

So in this courtyard, except for Chen Fan, only Jiang Lili can touch it a little, and no matter how they please Huang Ying, it doesn't eat the meat they give.

After raising the mouth, those stinky rats or something are naturally not in its consideration.

Chen Fan explained again, "The mice flying in the sky are not allowed to eat." ”

Seeing that the falcon nodded obediently, he let it go.

Chen Fan clapped his hands and pointed to the basket, "Huang Ying, take the little rabbit to the back." ”

There are two "houses" in the back barn, separated by a passage in the middle, where two piglets live on the west side, and a woodstack on the east side, which were later squeezed into two sheep and two horses.

Before preparing to raise rabbits, Chen Fan took Jiang Lili and them, moved all the firewood to the wooden compartment above the livestock shed, and took it out and put it under the courtyard wall, and then built half a wall with adobe bricks in the vacant space in the pigsty, dividing it into two, leaving most of the room for horses and sheep, and the small half for rabbits.

But this is only a stopgap measure, the rabbits will make holes, and the Sanhe soil here is only afraid that it will not be difficult for them.

In the past two days, Chen Fan plans to build another outdoor single-row rabbit house next to the livestock shed, and the last time he bought "Common Breeding in the Countryside" there is a rabbit house construction method, plus his level 3 bricklayer and level 3 carpentry skills, a small rabbit house is absolutely not a problem.

In addition, he also found the local method of fur tanning from the "Rural Sideline Production Knowledge", and the rabbits caught by the falcon before were used by him to make experiments and tanned into soft rabbit skins, which were kept to make leather clothes later.

If rabbit breeding goes well, you can also engage in a rabbit deep processing industry, from rabbit seedling cultivation to leather and rabbit meat production.

I just don't know if Secretary Yang has such courage.

Huang Ying carried the basket to the backyard, Yang Ju was still unwilling to think about it, and got some soil to block all the holes that could be seen in the yard.

In fact, it is useless, no matter what is living in the hole, since people can make holes, what effect can they have when they block the soil?

Chen Fan said with a smile, "There is quicklime burned before in the earthen kiln, pick a few pieces over, mix it with water, get some lime water and pour it in, no matter what is inside, it is definitely a dead end." ”

Limestone is one of the most widely distributed stones in the world, almost everywhere, in China, North China and Northeast China are the most, Nanhu Commune also has a small limestone mine here, very cheap, two yuan a car, casually pulled.

In the future, lime is indispensable for building a house, so Chen Fan bought 10 yuan and pulled it back, burned it into quicklime with an earthen kiln, and as long as he washed it with water again, he could get slaked lime and lime water, which was very convenient.

Hearing Chen Fan's words, Yang Ju's eyes suddenly lit up, and he found a pair of baskets and rushed out of the gate and ran to the back.

Chen Fan smacked his lips and said softly, "Just take advantage of this renovation of the earthen stove and toilet and open the back door." ”

Jiang Lili glanced at Liu Dan, who was going to the kitchen to cook, and walked over and whispered, "Xiaofan, you still have to think about how to protect your bacon and bacon first, as well as rice and rice, only a thousand days to be a thief, there is no reason to prevent thieves for a thousand days, in case the big mouse comes over again, it will be suffered." ”
