How should we do a good job of disinfection in the continuous greenhouse? Let ’s take a look at you:
1. Disinfection of the soil.
Pesticides are used for the types of diseases and insect pests in the soil, which are carried out from 10 days to 15 days before planting. If the withered disease is severe, it can be sprayed 100-200 times the Formalin liquid on the noodles or groove surface. It can be covered with a thin film for five days. After half a month, the pharmaceuticals will be volatilized. At this time, it can be sowed and planted. If there are underground pests, a certain amount of pesticides can be added during soil treatment.
2. Disinfection in the shed.
Disinfection in the shed 7 days to 10 days before sowing or planting. Each cubic meter is mixed with four grams of sulfur and eight sawdust grams. It is burned in the container, and smoked at seven o'clock in the evening.
3. Digestal disinfection.
If the withered disease is severe, soil disinfection can be performed before planting, or it can also be carried out in the planting gap pond. Use 50%todin 1.25 kg or 50%multi -bacterial spirit 0.75 kg or 70%pentaolin benzene benzenexylin about 1 kg of 1 kg of 1 kg Disinfection.
4. Disinfection of tools.
This is usually ignored by people. Some diseases are retained through the gaps of the work tools, and they are the accomplices of the spread of greenhouse diseases.
