How to stop a small screw in the ground? How to get rid of small screws in a vegetable patch

Spray tea bran. Liquid with 1 kg of tea bran, processed into powder, add 10 15 kg of water, fully stir and mix evenly, soak for 8 12 hours, take a clear solution, when found that there are snails on the stems and leaves of vegetables and melon flesh, pulp damage, spray on the stems and leaves or the crown, you can kill the screw.

2. Sprinkle plant ash.

In the evening, sprinkle the stems and leaves of melons and vegetables with dry and pure plant ash, if the stems and leaves are dry, you can spray some water first, so that the leaves are moist and then sprinkled, and the screws will not climb up the stems and leaves to bite the stems and leaves.

3. Sprinkle lime powder.

After heavy rain, a layer of lime powder is sprinkled around the trunk of the fruit tree, about 3 5 mm thick and 40 50 cm wide.

Everyone is familiar with screws, and there are several kinds of screws, some can be eaten and some can't. There is also a kind of screw that likes to run into the rice field and nibble on the root juice and nutrient water of the rice. But most farmers don't know the harm of this screw, and they put it aside, until the seedlings are getting worse and worse, and the pesticides are playing a lot but they don't get better, and finally the yield of rice has dropped a lot or can't find the reason, and the heart is still very contradictory, in fact, this is not the problem of seedlings, it is all caused by Fushou snails.

Fushou snail is an invasive species alien to agriculture, which is extremely harmful to rice. And it reproduces very quickly, giving birth to three generations every year, and the eggs of each generation float into small Fushou snail patients are also very fast. So in some rice fields, you will find that there are a lot of such small screws, and some are full of leaves, you must remove them when you see them.

The main breeding time of the snail is from May to August every year, which can be said to be a high-winding period for its reproduction, so everyone should start to dispose of it when it lays eggs. If the seedlings are injured by the snail during the delivery period, the effective delivery of rice will be reduced, so the yield in the future will not be high.

So how can we effectively stop these snails from running into the rice fields?

Some people may immediately think of using chemicals to deal with it, but I don't recommend that you do it, because chemicals can be harmful to the whole body of water, as well as to ourselves. I suggest that you can use an interceptor net to isolate when preventing the invasion of Fushou snails. It is best to use a kind of interception net with a relatively small gap, which can be used to intercept the inlet and outlet of the entire canal.

Medications can be used in the following three ways.

1. Spray tea bran liquid with 1 kg of tea bran, process it into powder, add 10 15 kg of water, stir and mix evenly, soak for 8 12 hours, take the clarification solution, when it is found that there are snails on the stems and leaves of vegetables and melon flesh and pulp, spray on the stems and leaves or the crown of the tree, you can kill the screws.

2. Sprinkle plant ash in the evening with dry and pure plant ash sprinkled on the stems and leaves of melons and vegetables, if the stems and leaves are dry, you can spray some water first, so that the leaves are moist and then sprinkled, and the screws will not climb up the stems and leaves to bite the stems and leaves.

3. Sprinkle lime powder After heavy rain, sprinkle a layer of lime powder around the trunk of the fruit tree, about 3 5 mm thick and 40 50 cm wide.

This type of screw is called a fine drill snail, also known as a long taper screw. It mainly appears in cabbage, cabbage, radish and other vegetables and various flowers, and feeds on the young shoots and young leaves of vegetable crops, and is an important pest in the seedling stage of vegetables in southern China. It is more frequent after rain.

You can check whether it is this kind of fine drill snail: the shell is small, the chitin is thin, fragile, transparent, elongated and tower-shaped, the shell is 3 wide, there is a spiral layer, each spiral layer grows slowly and evenly, slightly expanded, the spiral is high, slender, and tower-shaped. The body spiral layer grows slightly faster and expands.

The top of the shell is blunt, and the suture is deep. The shell surface is pale yellowish-brown or yellowish-white, with dense and slender growth lines, and the growth lines are thicker on the body snail layer. The mouth of the shell is oval, the mouth margin is simple, complete, thin and sharp, fragile, the outer lip is at an acute angle with the body snail layer, the axial edge is straight, slightly folded outward, and the inner lip is attached to the body snail layer, forming an inconspicuous callosum.

Method: 1Mulching cultivation. It is not only conducive to vegetable production, but also can effectively reduce the harm, but the cost is high, and it can be used if possible.

2.Eradicate weeds and clear ditches and drain stains. Helps to destroy the habitat and spawning grounds of snails such as snails.

3.After harvesting, plough and dry the soil in time. The adult snails are exposed to the ground and pecked by natural enemies, and the eggs are sunburned and broken.

4.Artificial trapping and killing. Use weeds and vegetable leaves to create a trap pile, and catch it intensively before dawn.

5.Sprinkle lime belt to protect seedlings. Spreading lime strips (90 150 ha hectares) or tea bran powder (45 75 ha hectares) on the edge of ditches, on the head of the ground or between ridges can provide short-term damage and protect seedlings.

6.Pharmaceutical prevention and control.

Booby-trap method. Poisonous baits such as soybean cake or corn flour prepared with snail dioxide (polyacetaldehyde) as an active ingredient are sprinkled on the ridges of the field in the evening to trap them.

Sprinkle granules. 6 mida granules (kg ha) were sprinkled after sowing or transplanting, or 8 snail or 10 polyacetaldehyde granules (30 kg hectares) mixed with fine soil and 20 kg were sprinkled in the evening between vegetable rows.

Spray method. In the evening or early morning or after the rain, when the snail crawls out and has not yet dived into the soil, spray 8 1000 times of snail kill solution or try 100 times of ammonia solution or 1 salt water spray.

You can try sprinkling quicklime on the ground.

After the rain in the evening after the sunny day, use the metasa.

With the improvement of living conditions, bonsai are actually becoming more and more common in life. Of course, it is also a personal preference for bonsai, or it is to purify the air and make it a little fresher. There are also skills in raising bonsai, some people raise potted plants, this branch and leaf are very lush, and some raise bonsai and die quickly, so bonsai is also a skill job.

So if there are many small snails in your potted plants, this is not good for the growth of the potted plants, how to quickly eliminate these small snails? Of course, it also requires skill, and it doesn't mean that you can get rid of it by doing it casually. The following will explain the skills of quickly eliminating many small snails in potted plants in life.

If there are many small snails in your potted plant, we choose the method to remove a layer of topsoil first, which is about 5 7 cm thick, this operation is mainly to remove the eggs and snails in the epidermis, as long as the insects and eggs are removed, then the small snail will disappear. Of course, after removing a layer of this skin, we also have to immediately fill in a layer of new soil, before filling this layer of new soil, we can sprinkle some quicklime in an appropriate amount, so that the benefits can completely eliminate the small snails.

In your potted plant, there are many small snails that can also be used in this way, that is, after removing the topsoil layer as above. Then soak the whole pot in water, the water can flow out of the pot, and leave it in the water for about 10 minutes, which is enough time to kill the pests in the pot. Then, we have to move the potted plants out and place them in a sunny and ventilated place indoors, which can also effectively eliminate small snails.

The two methods introduced above are actually very convenient and fast. If there are many small snails in your potted plant and you can't find a suitable method, then you can quickly eliminate the small snails through the above two methods. These two methods will hopefully solve your problem effectively.

You can use a sanitary ball, which is what we call mothballs, to grind the sanitary ball and put it in the potting soil to control underground pests. The pot is too damp, and it is easy to grow this if it is not too permeable and breathable, but it is much better with a clay pot.

The main reason is because the pots are too damp. Discard the snails and a few centimeters of soil on the surface, replace them with new soil, and sprinkle lime on the surface. There is also a mothball that can be placed on the surface of the soil to remove small snails.

Soak all the soil out and soak it in water, or soak the whole pot in water for a day and a half, and it will almost die. Try not to pour out the water that has been soaked in the soil, keep it for watering the flowers, it is fertile water, and the fertile water does not flow into the fields of outsiders.

Why do you want to destroy it? Eat the rotten leaves. It's good for decomposing into humus. It feels good for the soil. And they won't eat fresh leaves.

There is a simple way, flower water spray, a little is enough, the cheapest way to kill snails.

At this time, you can spray some salt water into the potted plant, and it will have an effect.

This is a fine drill snail.

How to destroy: Buckle all the soil out and soak it in water, or soak the whole pot in water, soak it for a day and a half, and it will almost die. Try not to pour out the water that has been soaked in the soil, and keep it for watering the flowers.

The fine drill snail is the order of the shank, and the drill bit snail family. Distribution: Hunan, Fujian, Guangxi, Guangdong, Hainan Island, Taiwan, Hong Kong, Macao, Southeast Asia and the islands of the Indian Ocean, Pacific Ocean and Oceania.

It hosts vegetables such as cabbage, kale, radishes, and various flowers. Feeding on the young shoots and young leaves of vegetable crops is an important pest in the seedling stage of vegetables in southern China.

Prevention and control methodsDuring the occurrence period of fine drill snails, 6% tetraacetaldehyde granules are selected square meters, and they are sprinkled in the evening on sunny days to kill snails and young snails. In addition, turning over the soil can also reduce the occurrence of fine drill snails.

I accidentally sprinkled the wind oil essence and went down to find that the snails spit bubbles first, and then all died.

As long as the little screw inside wasn't dead at the time, of course it could live. The outer screws are completely different from the inner screws.

1. Smell. If the whole bag of screws emits a stench, then there must be a lot of screws in it that are dead. Of course.

There are also versions of the surviving ones. Right.

2. Viewing the shape. Dead screws are generally deeply recessed with the cover of the screw not.

3. Look at the whole. If the whole bag of screws is left to stand for 2 minutes, some of the screws on it will quietly open the cover, indicating that the overall survival condition is good.

4. Screws and other soft shellfish have strong vitality. If the screws are not cleaned of the mud outside the shell, they can survive for more than a week when they are put into a woven bag. (The mud on the outside of the snail shell has a moisturizing effect, which is very important for the survival of the screw).

Most of these snails are made of aquatic weeds.

Brought into the fish tank, so after the aquatic plants are bought, they should be soaked in potassium permanganate for 10-15 minutes. And there should not be too many aquatic plants in the fish tank, because when the light is relatively strong, the fish tank will produce a lot of algae, so that these small snails grow quickly.

The snail is not very harmful to fish, but it is harmful to aquatic weeds. There are several ways to clear it.

1. Manual removal: small snails are attached to the aquatic weed blades or glass tank walls, you can clean the fish tank once, catch all the snails, and be sure to kill even the snail eggs, otherwise the snails will grow again.

2 Biological removal: You can put chocolate dolls, submarines or eight-figure dolls (all belong to puffer fish, generally sold in the market of flowers, birds, fish and insects), so that the snail fish will eat the snail, and it will not be harmful to the fish and aquatic plants. But the only thing to note is that the chocolate doll is 3-5 cm smaller and has a gentle temperament.

However, submarines have a rough temperament, and if they are just raised with some fast-swimming fish such as tiger skins or Australian rainbows, you can throw the submarine directly into the tank to destroy the snails. If it is a peacock, traffic light, etc., it is best not to put the submarine directly, you can first fish out the fish in the tank and put it into the submarine, after 3-4 days, there will be basically no snails left, and then take out the submarine and put the fish back in the original tank, the effect is obvious. Bazi dolls like slightly alkaline water, once the task is completed, try to remove it and raise it separately.

Therefore, there are many inconveniences.

3. Chemical removal: wash the fish tank with potassium permanganate, or remove it with a special snail remover for the aquarium. However, it is necessary to use the exact dosage to avoid harm to fish and aquatic plants.

4. When changing the water, use a straw to push the small snail attached to the cylinder wall to get it out of the cylinder wall, and suck it away.

Those are small snails. I don't know what kind of fish you have in your tank, you can keep one or two small meat fish in it and let them eat those snails clean. It's fine to be like a koi.
