The easiest way to disinfect flowers is to expose them to the sun, especially those dug in the field. There are many small insects in the soil, which must be disinfected before use.
Put the soil in the place of direct sunlight, spread it into a thin layer, expose it to the sun for more than one week, or put the soil in a plastic bag and seal it, and expose it to the sun, all of which can achieve the goal of sterilization and killing insect eggs.
1. Now winter and spring alternate, the temperature in many places is not very high, and the sun is not very strong, so we have to use artificial methods for disinfection. Use boiled water to pour directly on the soil until the whole soil is completely poured, and pour several times more. Then pour out the extra water and dry the soil to kill the eggs and bacteria.
2. If there is an abandoned iron pot at home, it will be better. Put the soil in an abandoned iron pot, and then put it on the gas to continuously heat and stir fry, using the high temperature to kill the egg bacteria in the soil. About half an hour later, let the soil dry naturally, and then it can be used directly!
If there are carbendazim or sulfur powder in the house, it will be better. Put the soil in the foam box, add a layer of soil, and sprinkle a layer of medicine evenly, then continue to add soil to add medicine, like a sandwich fertilizer.
When the foam box is filled, seal it with plastic bags or covers. About 7-10 days later, open the lid or plastic bag, and stir it up enough to ventilate.
In addition to a little more fungus retting soil, there is also a simple way, that is, buy the medicine absorbed inside, and bury it in the flowerpot, so that when watering, the medicine will open with the hydration, and the egg bacteria in the soil will be killed.
If there are small insects in the pot soil, you can also directly spread a layer of collected plant ash and ash on the pot surface, which can not only prevent the small insects from laying eggs in the soil, but also let the ash flow into the flower pot along the water when watering, so as to kill the egg bacteria in the soil.
