CATDOLL : CATDOLL: What disinfectant should be used for soil used to raise earthworms (What is the best disinfectant for soil used to raise earthworms)

1. How to disinfect the soil for raising earthworms?

Of course, earthworm manure must be sterilized before growing flowers. Because it contains insect eggs, bacteria, etc. If it is not disinfected and sterilized, and flowers and plants are directly cultivated, it will affect the growth of the plants.

The sterilization method is very simple. You can mix an appropriate amount of insecticide and then place it in a high temperature environment to kill insects and sterilize. This is safer. Mixing in an appropriate amount of earthworm manure can make the soil more nutritious, with better drainage and ventilation, which is conducive to growth.

2. What is used to sterilize the soil for breeding earthworms?

To kill earthworms, it is best to use quicklime, which is also the easiest to buy and relatively cheap.

1. Disinfection and sterilization

After quicklime absorbs water, it undergoes a chemical reaction and releases a large amount of heat. Therefore, after quicklime is applied to farmland and buried in the soil after deep plowing, it will absorb water, mature, and release heat, rapidly increasing the soil temperature, which can play a role in disinfection and sterilization, and reduce the occurrence of diseases in the soil. In addition, high temperature can also kill pests in the soil, achieving the effect of pest control.

2. Improve the physical and chemical properties of the soil

Quicklime absorbs water to generate calcium hydroxide, an alkaline substance that can neutralize the acidity of the soil. Moreover, spreading quicklime can increase the calcium ion content in the soil. Calcium ions are a good binder for the soil, which can form soil aggregates, make the soil loose, and reduce soil compaction. Therefore, spreading quicklime can improve the physical and chemical properties of the soil, thereby achieving the effect of increasing crop yield and quality.

In addition, spreading quicklime can increase the activity of soil microbial flora, improve the soil environment, improve the conditions for crop growth, and so on.

3. How does chlorine dioxide disinfect earthworms?

Methods for disinfecting live bait with stabilized chlorine dioxide When using stabilized chlorine dioxide to disinfect live bait for aquatic animals, the concentration of stabilized chlorine dioxide should be flexibly controlled according to the type of live bait. (1) When disinfecting plankton such as rotifers, it is advisable to soak them in a 1.5 mg/L stabilized chlorine dioxide aqueous solution. In a container of appropriate size, fill a certain amount of clean water, dilute the stabilized chlorine dioxide in it, and soak the plankton such as rotifers in it for 5 to 10 minutes. (2) When disinfecting aquatic animals such as earthworms and Artemia, it is advisable to soak them in a 3 mg/L stabilized chlorine dioxide aqueous solution for 5 to 10 minutes. (3) For disinfecting live bait, you can also use a stabilized chlorine dioxide aqueous solution with a concentration of 0.01 mg/L to 0.1 mg/L to soak the feed organisms for 8 to 72 hours. 2. Methods for disinfecting fresh bait with stabilized chlorine dioxide When using stabilized chlorine dioxide to disinfect fresh bait for aquatic animals, you should choose a more appropriate method according to the type of fresh bait. (1) When disinfecting fresh fish, snails and river clams, you can use the method of soaking them in a stable chlorine dioxide aqueous solution. Dilute the stable chlorine dioxide in clean water to prepare a solution with a drug concentration of 5.0 mg/L, and then soak the fresh fish, snails and river clams in it for 10 to 20 minutes. (2) When disinfecting frozen fish, snails, river clams, slaughter scraps, etc., you can use the method of soaking them in a stable chlorine dioxide aqueous solution with a concentration of 10.0 mg/L. That is, soak fresh fish, snails, river clams, slaughter scraps, etc. in it for 10 to 20 minutes before feeding. III. Methods of using stable chlorine dioxide to disinfect feed for aquatic animals When using stable chlorine dioxide to disinfect feed for aquatic animals, the more appropriate method should be selected according to the type of feed. (1) When disinfecting powdered feed, you can add stable chlorine dioxide at 0.1% (that is, use 1 kg of stable chlorine dioxide in 1 ton of feed) and prepare it into granular feed for feeding. (2) When disinfecting pellet feed, you can use a method of spraying a 20.0 mg/L stable chlorine dioxide aqueous solution on the pellet feed. Feed the feed 10 to 20 minutes after spraying the drug. (3) When disinfecting plant feed such as aquatic plants, you can use a method of soaking in a stable chlorine dioxide aqueous solution. Dilute the stable chlorine dioxide in clean water to prepare a solution with a drug concentration of 3.0 mg/L, and then soak the plant feed such as aquatic plants in it for 10 to 20 minutes. It is well known that disinfecting bait and feed for aquatic animals is not only beneficial for preventing various infectious diseases of aquatic animals, but also an important and effective measure to prevent the corruption of bait and mildew of feed.

4. How to remove flying insects in the soil where earthworms are raised?

It is quite common to see small flying insects when raising earthworms. This is usually because too much food is put in, causing it to rot inside, attracting some flies and other flying insects to lay eggs.

It is almost impossible to completely eliminate them. The only way to reduce their numbers is to control their food. Each feeding must be finished within 4-5 days. Also, do not feed them dairy products, oily meat, etc., as these are more likely to attract flying insects.

5. Can thiophanate-methyl and thiophanate-methyl be used as soil disinfectants? How to mix them?

As a fungicide, chlorothalonil can only protect and inhibit fungi. Although thiophanate-methyl has a fungicide effect, it is not very effective for soil disinfection. Here is a suggestion for you. If the amount of soil is not much, within 10 cubic meters, you can use high temperature and high pressure sterilization method. You need a high pressure sterilizer, which is the most thorough sterilization. When the amount of soil is large and there is no sterilizer, you can use chemical agents for sterilization, such as "Bisu Mie". It is a highly effective soil disinfectant that kills nematodes, fungi, bacteria, and weeds. It is a product imported from Germany and has a good effect.

6. Can potassium permanganate solution kill earthworms?

No, potassium permanganate is a strong oxidant and can also cause damage. You cannot plant flowers directly in earthworm soil. There are many microorganisms and bacteria in the soil, which are not conducive to the growth of flower roots. If you want to plant flowers with earthworm soil, you must expose it to the sun to kill the eggs in the soil. You can also soak it in potassium permanganate solution for disinfection, otherwise many earthworms will breed in the soil and damage the roots of flowers.

7. Can potassium permanganate kill earthworms in flower pots?

Can.

It is not good to have earthworms in the soil, so we need to pay special attention when we grow roses to reduce the chance of earthworms appearing in the pots. Generally, we can put the soil for growing roses in strong sunlight, dry it for 2 to 3 days, and then stir it repeatedly to let the soil dry thoroughly. You can also stir-fry the soil in a pot, or add potassium permanganate to the soil for disinfection before use, which can prevent earthworm eggs and bacteria in the soil.
