In fact, the plants, flowers, yellow leaves or insects in the home sometimes have problems not with the usual maintenance, but with the cultivation of the soil. Generally, when we raise flowers again, we don't remember to disinfect the soil. In this way, the soil will contain a large number of bacteria. It's normal to recruit insects after a long time and insufficient nutrients. Today, Huahua will teach you several methods of soil disinfection. In the future, remember to disinfect before raising flowers, so there will be no problem

1、 Exposure disinfection

In general, when we sterilize items, the first thing we think of should be high-temperature disinfection. Because too high temperature can easily eliminate bacteria, this method is also suitable for soil disinfection. The simplest way to deal with it is to move the soil prepared for raising flowers outdoors when the temperature is high in spring and summer and the sun is hot. Spread it out in the sun and expose it to the sun. After drying for almost two or three days, you can collect it and keep it for future use

Sometimes the soil we raise flowers is rotten leaf soil or garden soil obtained from the roadside. At this time, it is inevitable to mix some small insects in it. It looks disgusting and annoying. If we want to eliminate them, we can pour the soil into a closed container. In this way, if we put it in the sun for a few days, it can kill insects and disinfect. In the future, we can plant flowers with garden soil without fear of insect invasion

2、 Microwave oven disinfection

The use of microwave oven disinfection method is relatively limited, which requires that there are unused old microwave ovens at home. We all know that the temperature of microwave oven is very high when heating. We put the soil that needs disinfection in it and turn on the heating function. In a few minutes, the high temperature can eliminate all bacteria and pests in the soil. This method is really simple and rough

3、 Boiling water disinfection

Boiling water disinfection, as the name suggests, is to use boiling water to irrigate the soil for disinfection and sterilization. After the soil is watered with boiling water, pay attention to drain the water and dry it in the air. Generally, the effect of this method at one time is far from enough. If you want to have a good effect of sterilization, you can come more times. However, pay attention to safety when pouring boiling water to prevent scalding

4、 Stir fry disinfection method

We need a big iron pot to carry out this method. When ready, pour the soil into the iron pot, heat it to 140 degrees and stir fry it for about 50 minutes to disinfect it. However, this method is generally only applicable to a small amount of soil disinfection. After all, there is too much soil to hold in an iron pot, isn't it

5、 Drug disinfection

Drug disinfection is a common disinfection method, and it is also the method with the best sterilization effect. We can mix Carbendazim and other disinfectants into solution in proportion, and then spray them on the soil. After spraying, we need to stir the soil, and finally seal it with plastic wrap for about 3 days, so that the pests and toxins in the soil will be completely cleaned up

If your plants often have yellow leaves and can't find problems, you can use these five disinfection methods to disinfect the maintenance soil when changing pots. I believe that after disinfection, the flower plants at home will grow better
