Can nutrient soil be sterilized in winter?

Sun exposure If you're growing plants in the summer or autumn when the sun is very strong, that's great, and Nicky can use sun exposure to sterilize and detoxify. Spread the soil you want to plant on a smooth floor, or on an iron plate, the soil should not clump, it is best to use a tool to separate the soil into small pieces, spread it into a thin layer that is easier to sterilize, and in about a week, you can roughly kill the bacteria in the soil. Pay attention to turning the soil from time to time to fully expose the soil during exposure.

Film covering sterilization method When the temperature is relatively high in summer, you can use film covering sterilization method, put the selected soil in the selected container, water it with water, wait until it is completely watered, remove the excess water, and then move the container to the sun to be exposed, be sure to use a black or darker film to seal the opening of the entire container, and you can buy it after about a week of exposure.

Boiling disinfection method Put the selected soil into a pot, add appropriate water, generally overflow the soil and then raise the depth of a palm, and then heat it with fire to boiling, and continue to boil for forty-five minutes to kill many bacteria. After cooking, take out the soil and let it dry in the sun to dry the water. When using this method, you should pay attention to using a pot that is not commonly used to cook, otherwise many flower friends will probably not use this pot to cook rice again.

Nutrient soil can also be sterilized in winter by drying in the sun.

In winter, we put the nutrient soil in the balcony, because the front of the balcony is glass, put the soil on the windowsill, pave it with the sun, it will also play a sterilizing role, because the temperature of the glass to receive sunlight is also very high.

If the newly purchased nutrient soil is not used for seedlings and cuttings, the seedlings and roots do not need to be disinfected, physical methods: exposure to the sun, steam; Chemical methods: formaldehyde, potassium permanganate.

Exposure to the sun and other practices are for disinfection and sterilization.

Yes, with ultraviolet rays, you can.

There are almost no nutrients after soil sterilization.

After sterilization and disinfection, the old soil has been relatively clean, but there is almost no nutrition, and it has been compacted, and the air permeability is very poor. You can add something to make the soil fertile. There are many things that can be used to make soil, such as soaked soybeans, coffee grounds, rotten vegetable leaves, and so on.

Under the pot, first spread a layer of old soil, then a layer of prepared soil material, and then spread the soil, and repeat the operation until the pot is full. Then pour some water into the soil.

Several methods of soil disinfection:

1. Exposure to the sun. We can put the soil in the scorching sun for a few days, and it is best to spread the soil, although it will destroy the results of the soil and microorganisms to a certain extent, but the effect of sterilization is still good.

2. Disinfection of boiling water.

Use boiling water, water directly into the soil, water it several times, then drain the water, dry it a little, and you can use it to plant flowers when the soil is not so sticky.

3. Drug disinfection.

With bactericidal drugs, commonly used bactericides such as carbendazim, chlorothalonil, fludichlorium, oxachlorine, dixon, etc. Mix with water and then spray it onto the soil, preferably with a protective film to seal the mouth of the basin for 2 to 3 days.
