What are the pests of farmed earthworms, and what are the breeding techniques of earthworms?

1.Poison gas poisoning disease: The bottom layer of the carrier is aged until it is corrupt, and it is not breathable for a long time, so that a large amount of carbon dioxide gas is suspended between the base materials, resulting in the lack of oxygen and the earthworm rushes to the surface, and then the anaerobic spoilage bacteria, sulfide bacteria, etc.

Symptoms: A large number of earthworms gushed out of the surface of the base material at the beginning of the disease, and there was an obvious tendency to escape; Then it was found that the earthworm was paralyzed locally or even the whole body, and the dorsal hole also discharged yellow or grass body fluids, and a large area died in a clump. Prevention and control methods:

Attention should be paid to the ventilation of the base material, frequent replacement of the base material and removal of vermicompost. Once the disease appears, the feed bed should be quickly thinned, the toxic feed should be removed, the base material of the feed bed should be loosened, and vermicompost should be added to adsorb the toxic gas. 2.

Atrophy **: Metabolic inhibition caused by the base material temperature below 18 or above 28 for a long time; The earthworm pond is too small, the base material is too thin, resulting in poor shading, and the earthworm is exposed to light for a long time, which affects the biochemical disorders in vivo and in vivo. Symptoms:

The worm body is short and thin, dark in color, slow in response, and has a food refusal reaction. Prevention and control methods: strengthen the management of the benign balance between the ecological environment and the microecological environment, and disperse the diseased worms into the normal earthworm population to polyculture, so that they can return to normal.

This condition is caused by uncontrolled management and generally does not cause serious consequences. 3.Rats, snakes and frogs plug loopholes in the breeding sheds, add protective covers, and scatter quicklime around the sheds to form a line of defense to prevent them from entering.

4.Centipedes, mole crickets, and black slugs take advantage of their nocturnal foraging properties to be captured by hand at 9 to 10 p.m., or killed by sprinkling potassium permanganate on their active areas. 5.

Before ants release earthworms, 3% chlordane powder or heptachlor powder can be spread around the breeding facility, and 25 45 grams per square meter can be used (do not overdose, so as not to injure earthworms by mistake). In the high temperature season and the young worm breeding bed, it should be applied less, and the validity period can generally be maintained for about 15 days after sprinkling.

Under normal conditions, there will be ants, frogs, centipedes, poultry, etc

1.Breeding method: Ten years after the establishment of the farm, we have been insisting on open-air compost farming, I think, this method is low-cost, is the best way to produce earthworm products on a large scale, without any investment in equipment, the use of all idle land, as long as the unfermented cow dung, horse manure, pig manure made into 15-20 cm high, wide meters, length is not limited, put into the worm seeds, cover the straw, shading and moisturizing, you can breed.

2.We started to raise from a few square meters, until now, more than 200 acres of land are used in this method, its advantage is that it is easy to operate, save a series of work of stacking and fermentation, bait to keep nutrients from loss, improve the growth rate of earthworms, and is easy to promote and apply in rural areas. This method also has its drawbacks:

Once the bait is heated, the earthworm is dead and the body is gone, and in summer, even after the rainy day and the rainstorm, the bed is not breathable, and there is a phenomenon of escape.

3.The way to avoid this is to have new bait for each breeding bed. The bait is piled up in blocks to create good bottom-up conditions for earthworms. The key to this method is to keep the water content of the bait at 60-70%, not too dry and too wet, otherwise the bait will heat up and die.

Earthworms like moisture and are afraid of dryness: the water content of the earthworm is about 80%, and the water content of the bait is required to be 60%-80% (to hold the material by hand, and the finger seam dripping shall prevail), so the water content of the breeding bed is required to be more than 60%, so that every day or every 1-2 days, it must be watered once, the water is not too large, but it is necessary to water thoroughly and connect the lower layer of material, and the watering time is to water at noon in winter, water at night in summer, and water during the day in spring and autumn.

Like air, like quiet, loose bait is conducive to the growth of earthworms, our years of experience is to turn the bed over (about 20 cm thick) before feeding to increase ventilation. This is important because over the years, we have found that the number of earthworms in the bottom of the bed soil is very small, but the bait is still available, mainly because of the lack of air, which is not good for the growth of earthworms.

Summary. Hello dear, happy to answer for you! Breeding earthworms can be used to remove insects with trichlorfon powder!

The specific methods are as follows:1Earthworms can be killed with trichlorfon powder, which only needs to be sprinkled on the surface of a soil, and then mixed with the soil and watered to have an effect.

2.If you want to kill an earthworm, the most direct way is to soak in water, because the earthworm is afraid of water, as long as you water a lot, let the earthworm in the soil be soaked in water overnight, it will crawl out of the soil on its own. If the number of earthworms is too large, you can use dianong and ground insect elimination.

When using, in a place where earthworms are concentrated, mix the diluted dianon into the soil. Pesticides must not be abused when used, because pesticides are not omnipotent, and too many pesticides will cause pesticide damage.

Hello, you're a medicine for earthworm removal, right? <>

If you want to kill an earthworm, the most direct way is to soak it in water, because the earthworm is afraid of water, as long as the manuscript instructs to water a lot, let the earthworm in the soil be soaked in water overnight, it will crawl out of the soil on its own. If the number of earthworms is too large, you can use the Dianon and Ground Insect keys or Elimination. When using, in a place where earthworms are concentrated, mix the diluted dianon into the soil.

Pesticides must not be abused when used, because pesticides are not omnipotent, and too many pesticides will cause pesticide damage.

Hello dear! Breeding earthworms to remove insects with pest net drugs! It is an insect killer specially used for breeding earthworms!

Under the normal dosage conditions, there is no toxic effect on earthworms, but some such as chlordane, heptachlor, dichlorvos, Tianji bromide, chloropicrin, simasan purin, carbaryl, furazolan, aldicarb, copper sulfate, etc., are very toxic to earthworms. So don't use it! Hope mine helps you!

Have a great day! All the best!

Earthworms generally do not eat pests, but if they are small enough, they may not be able to distinguish and eat together. Earthworms themselves are omnivorous animals, like humus and decomposed substances of various animals and plants, etc., and generally do not attack or prey on insects, but if the insects have died and degraded, they are not picky.

1. Micro pests

Earthworms generally do not have the ability to prey on pests, but if the larvae of the pests are small enough, there is also a possibility that they will be mixed in the daily food of earthworms or mixed in humus to be eaten by earthworms, but this possibility is very small, and generally earthworms only eat humus and degradants of various animals and plants.

2. Dead animals

In most cases, earthworms eat the decaying and softening matter left behind by the decay of leaves, grass leaves and branches in the soil, but if the dead body of an animal is degraded in the soil, as long as the initial degradation process of decay and softening is carried out, the earthworm can feed on these animal humus.

3. Eating tendency

Earthworms are not picky eaters, but they also have a certain tendency, it prefers to eat sweet, sweet and sour fruit residues or vegetable spoilage, generally will not take the initiative to eat bitter and spicy vegetable and fruit residues, especially like animal spoilage, daily life is to eat various humus in the soil to satisfy hunger.

4. Precautions

Although the diet of earthworms is very wide, in most cases it can only serve as a relatively low-level degrader, mainly to accelerate the decomposition and degradation of dead animals and plants, and to loosen the soil for the role of soil, it has no active ability to attack predation, and can not do anything about inorganic substances such as glass, metal, masonry, cement, etc.

1. Earthworm is known as the world's best protein feed, it contains extremely rich nutritional value, earthworm contains 18 kinds of amino acids, various minerals and vitamins. Therefore, earthworms can be used to breed aquatic products such as loaches and yellow eels, which helps to increase the production of aquatic products.

2. Earthworms can also be used to raise pigs, chickens and other poultry, and improve their own nutritional value, and earthworms can also be made into earthworm powder as a growth agent for pigs. Using earthworms to raise pigs, chickens, ducks, yellow eels, mud front and loach not only grows fast, the meat quality is good, but also can cost less.

3. Earthworms can also process urban garbage waste, purify the environment, accumulate fertilizer, etc., which solves the problem of garbage disposal in various urban areas.
