What method can be used to get rid of leeches in rice fields?

In the past, there were leeches wherever there was water in the fifties and sixties, and leeches were everywhere at that time. If the feet of a paddy field are full of bites, people who have never planted the land will cry when they see it. It's not terrible to get used to it in the countryside. The leeches mainly suck the blood of animals and reproduce quite quickly in the water. There are also leeches in wet woodlands, and leeches in woodlands are particularly painful and itchy. Leeches are rarely seen in the fields now, and they are mainly killed by pesticides and fertilizers. Leeches are most afraid of lime pesticides and fertilizers, which is the bane of leeches and the most effective.

When it comes to leeches, it's terrible. If you have bitten on your feet and sucked blood, you are not afraid. If you see leeches leaping from the side, it's even more terrible. In the 196s, leeches in paddy fields were all killed by lime. Lime also controls rice diseases and insect pests. Now, rice fields have long since been free of lime.

leeches are amphibious invertebrates. They mainly swim in water and crawl on land. They usually feed on the blood of animals. When it comes to leeches in rice fields, they are the most abundant in rice fields in the 195s and 196s. They mainly like to live in cold water fields at the deep feet of mountain villages and in ponds and reservoirs, and bite people and animals whenever they see them.

In the past, there was a saying in our countryside that "the grasshopper listens to the sound of the water, and the beggar calls for the sound of the drum", which means that as long as the grasshopper in the field hears someone moving, plowing cattle, crawling with loaches and eels, and frogs and snakes making the water sound, the grasshopper in the field will rush in and catch up with the bite. If you bend and insert the field in the field, your feet will be covered with glue if you are not careful.

leeches also have a special function. Their body fluids contain an anesthetic. When they suck the blood of animals, they are painless and itchy, and it is easy to paralyze people.

From the above analysis, we can see that leeches are indeed harmful amphibians, and it is necessary to eliminate them. So what methods can be used to eliminate leeches in rice fields?

from the point of view of environmental protection, we can usually use 15-2 Jin of fresh raw stone per mu of rice field when we are rotary-tilling the rice field for the first time, or when rice seedlings are inserted for intertillage, and use the high temperature and alkalization generated by quicklime when it meets water to kill grasshoppers in the field. Quicklime can also change the soil quality, which has two effects.

The second method is to hammer the rapeseed cake, put it into a bucket, add some spicy herbs, soak it in boiling water at a ratio of 1: 1 for 2 hours, and then pour the oil tea cake and spicy herbs into 1cm of field water with a ladle at noon on a sunny day. In less than two hours, all the grasshoppers in the field will die, and the withered tea cake can also be used as fertilizer without polluting the water source.

the third method is to use ammonium bicarbonate as rice base fertilizer after ploughing, and use ammonium gas volatilized from ammonium bicarbonate to poison the leeches.

Besides, when we grow rice, other chemical pesticides are the killers of leeches, which can kill leeches in rice fields. What do you think? Welcome everyone to comment!

leeches are also called leeches, and they are also called grasshoppers here. I also have a lingering fear of leeches. I remember when I was a child, I was often stuck on my feet by leeches when I followed my parents to transplant rice seedlings. Leeches are mainly blood-sucking, and soon it will climb on the roots of your feet unconsciously when you get into the water. It will let go and swim slowly when it is full of blood. What should you do when you meet the leeches when transplanting rice? You can find something to beat it, or rub it with river sand, and you can get rid of the leeches.

At present, there are almost few leeches in rice fields, and many leeches have been poisoned because of the use of more pesticides. Not only leeches, but also some other small animals are rarely seen, such as loach and eel. I remember that in the past, besides grasshoppers, there were also many loaches and ricefield eels in the fields, and now there are more drugs used, which also leads to fewer and fewer of them.

So using pesticides is also one of the ways to get rid of leeches. Because when you plant rice, you will spray pesticides on rice. These pesticides can help you eliminate leeches. Besides using pesticides to get rid of leeches, other methods can be used. For example, use quicklime. Sprinkle quicklime evenly in the rice field, stop the water inflow and let it dry for a few days. It won't be long before the leeches are eliminated.

Another method is to use oil tea cake to get rid of grasshoppers. Oil tea cake is the oil residue squeezed from camellia oleifera seeds. Our rural areas are also the main areas where camellia seeds are planted. The output of tea oil is also more. I remember that some villagers also used oil tea cakes to get rid of leeches. Oil tea cake has the effect of killing insects. When it is spread in rice fields, it can not only get rid of leeches, but also get rid of other pests. However, everyone should also pay attention to the fact that oil cakes should not be scattered in fish ponds, which may be poisoned by fish in fish ponds.

The above are some common methods for our farmers to get rid of grasshoppers. There are other good methods that you can leave a message to share. Thank you.

There are rice fields in the hometown of Xiaocai Mountain. When rice is planted twice a year, there are leeches in the rice fields. In the early years, there were more leeches, but now there are fewer. Then what method can be used to get rid of leeches in rice fields? Let's talk about it as follows:

1. Paddy fields are plowed and exposed to the sun in autumn and winter

leeches live in water, so they can't live without water. Therefore, to get rid of leeches in paddy fields, that is, drain the water in paddy fields; This practice is difficult to do at ordinary times, usually after the autumn harvest. After the autumn harvest, there is less water in the rice fields. In addition, it is windy and dry in autumn and winter, and it rarely rains. The ploughed rice fields are exposed to the sun, so that the leeches hidden in the mud have no hiding place and the living environment is destroyed. Paddy fields with higher terrain are easier to dry in autumn and winter. People in rural areas generally like to do this, and the operation is simple. After several months in autumn and winter, leeches are rare in paddy fields when they are cultivated in spring.

2. The leeches who use quicklime

have no protective shell, and are vulnerable to some irritating things. The quicklime is alkaline, which reacts with water to produce high fever, but the leeches can't stand it. It is not difficult to obtain quicklime. In rural areas, farmers usually scatter quicklime in the paddy field when the water in the paddy field is relatively low after plowing the fields and before transplanting.

of course, if the paddy field is large, the amount of quicklime is also large, and farmers are generally reluctant to use quicklime, so they usually choose to plough and expose the paddy field in autumn and winter.

3. Use peanut cakes

The peanut cakes mentioned here refer to the residue left after husked peanuts are squeezed from the soil in rural areas, and the local dialect in the hometown is called Mahuo (roughly transliteration). In the past, peanuts planted in rural areas were used to extract oil, and some were used to feed pigs, while others were used to fertilize fields, saying that they could kill insects and fertilize fields.

4. Control pests and indirectly get rid of leeches

Of course, there will be pests when rice is planted in rice fields, and people spray pesticides to control pests, and those pests are leeches' food, which will indirectly get rid of leeches, which is one of the reasons why people do not deliberately get rid of leeches, but leeches in rice fields are becoming less and less. What method can be used to get rid of leeches in rice fields?

at the mention of leeches, people will be frightened and have a lingering fear. Especially the girls who grew up in the countryside, or the educated youth who were sent from the city to the countryside, they were all once bitten by grasshoppers.

The grasshopper is an amphibious reptile, which often lives in fresh water or on the leaves of vegetables on the shore. It is not easy for leeches to attack people and animals on the shore, but when people and animals go down to paddy fields, they become their sacrificial products, and there will always be a lot of bright red blood on their feet and legs bitten by leeches. Sometimes it's hard to get rid of it if you want to pull it out, and it scares many girls to cry and call their parents.

I remember when I was a child, I went to the fields to catch earthworms, but I was bitten by an grasshopper. The blood kept flowing, and I couldn't get it off even if I tried hard. I ran home crying and told my father that I couldn't get it off because of the grasshopper bite. Dad comforted me not to cry and not to be afraid, so he patted my calf twice with his big palm and the grasshopper fell down. Later, my father brought salt for cooking from home and sprinkled it on the leeches. Soon, the leeches rolled over and over on the ground, and a lot of greasy liquid permeated from their bodies. Finally, the leeches became smaller and smaller and died.

From this point, it can be proved that the leeches are most afraid of salt. However, there are many and deep waters in the paddy field, so how much edible salt should be given to kill the leeches once! This seems unrealistic.

I remember that when transplanting rice in the production team, the team would sprinkle quicklime before transplanting rice, and then rake it and kill the leeches. Later, all kinds of highly toxic pesticides were used more, and leeches became less and less. Nowadays, working in paddy fields is no longer afraid of being bitten by grasshoppers. With the invention, production and popularization of paddy socks, farmers wear them when they work in paddy fields. Do you still have leeches in rural paddy fields?

Catch, dry in the sun and sell to pharmacies.

The best choice of quicklime

It is the most effective and pollution-free method to kill leeches by sprinkling dried lime powder in rice fields. Although killing with highly toxic pesticides is very effective, there will be pesticide residues that will also have an impact on farmers and future agricultural plants. The effect of using dichlorvos with low toxicity and low residue is not ideal. When leeches are contaminated with lime powder, they will fester and die, and in alkaline water with lime, they will also die of physiological acid-base disorder. However, the strong alkalinity of lime can only be maintained for a short period of time, and it can be diffused and desalinated after killing insects, which is also beneficial to improve the strong acidic old swamp soil.

when a leech bites you, don't pull it off with your hands. Because the leech has two suckers, it may make it suck more tightly. At the same time, hard pulling will make its mouthparts break under the skin and cause infection.

After being sucked by leeches, you can pat your arms and thighs or other bitten places. This kind of shock will make leeches fall off. Or coated with strong brine on leeches, or coated with soapy water, tobacco oil, wine, vinegar and so on. Soon, leeches will fall to the ground.

why do people bleed after being bitten by leeches?

The saliva it secretes when it bites people contains an anticoagulant, also called hirudin, which can make the blood of the wound not coagulate, so people will bleed endlessly after being bitten by leeches. This is a wonderful way for leeches to be gluttonous. There are suckers at the front and rear ends of their bodies, which can be used to adsorb their bodies on people's skin and continue to suck. If you are bitten by a leech, you can squeeze some blood out of the wound by hand, so you can stop the bleeding.

There are not as many leeches in the farmland as before! Not only leeches, but also the favorite loach, eel, green crab and small crucian carp are not many.

leeches, also known as leeches, are mollusks that suck animal blood to survive. Many people are a little scared when they see this soft thing, and rural people seldom take it seriously. There are many ways to eliminate leeches, so I will tell you a few today:

First, lime: lime can be used not only in building repairs, but also in many places in rural areas. Sprinkling it in the soil can neutralize the soil, sprinkling it on vegetables can remove snails, and it can be used to make rice tofu at home and disinfect fish ponds.

If you want to exterminate leeches, fill the ploughed farmland with water, sprinkle it with 3 kg of quicklime powder per mu, turn off the water and let it dry for a few days, let alone leeches, and as long as they swim in the fields, you can't escape (except frogs). People must wear water boots when spreading quicklime, so as not to be burned by quicklime.

the second kind, tea withered: many people may not know what this is. This is the tea cake left over from the tea seed oil pressed in the south. In the south, when there is no washing powder and soap, it is used to wash clothes in places with tea withered. Tea withered leaves contain a special substance, called tea saponin, which can enter the blood through fish gills and make fish die of hemolysis. Many people in rural areas use tea withered leaves to poison fish.

tea blight can not only poison fish, but also deal with leeches, loaches and ricefield eels easily without much effort. Now they are all mechanized operations, and there are not many times to go to the fields. Farmers rarely use this method to poison leeches, eels and loaches.

the third kind, ammonium bicarbonate: speaking of this kind, people who know and use this kind of fertilizer are no longer young. This is what we rural people often say about carbon ammonia. Now we all use compound fertilizer, and few people use carbon ammonia.

Turn off the water and sprinkle carboammonia in the ploughed fields. When it comes to water, it's especially cool, and it's especially choking. If you don't get it, tears will choke you out. Turn off the water for three days, the bigger the sun, the faster the leeches will die, and other loaches, eels and small miscellaneous fish will not escape.
