The methyl thiophanate or carbendazim powder disinfection method is mixed with fine soil at a ratio of 1:100 with 50% thiophanate or 50% carbendazim powder, and the soil is sprinkled into the seedbed before and after sowing. In addition to preventing seedling pests and diseases, this method can also prevent blight.
Disinfect the pentachloronitrobenzene with 40% chloral nitrobenzene 8 g plus 40~50 kg of fine dry soil. Mix the seedbed before sowing. After the water seeps, take 1/3 of the soil. On the surface, the seeds of the buds are sowed, and then 2/3 of the soil is covered on the seeds to sandwich the seeds in the middle of the soil.
The anti-Keisson disinfection method uses 95% of the 95% dikesone wettable powder, and 10 kg of fine soil is mixed. The bed soil is watered before sowing and sprinkled into the seedbed. 95% dikesone wettable powder can also be used. Spray the seedbed with double liquid.
2 to 3 weeks before the start of the formalin disinfection method, the seedbed soil is loosened, 40 kg of water per square meter is applied to the bed soil, and then covered with an opaque cover for 4 to 5 days. After the covering, the soil was loosened, and after 2 weeks, the liquid was evaporated and then sown.
The disodium ammonium disinfection method is to mix 50% of the dexamethasone solution into 300~400 times liquid, and it can be poured on the surface of the bed soil by 3~5 kg per square meter.
The ferrous sulfate disinfection method uses 3% ferrous sulfate solution to treat the soil, 0.5 kg per square meter of the drug solution; 50% water-soluble sensitium ammonium 350 times solution, 3 kg of dilution solution per square meter of nursery soil, It has strong bactericidal power and can penetrate into plants. After decomposition, it has certain fertilizer effects. It can control various diseases of black spot, downy mildew, powdery mildew, blight and bulbous bulbs.
Bordeaux liquid disinfection method is used in an equal amount (2.5:2:100) Bordeaux mixture 2.5 kg per square meter of nursery, and 10 g of Sai Li San is sprayed on the soil. After the soil is slightly dry, it can be sown or cut. . It has obvious effects on spot disease, black spot, gray mold, brown spot and anthracnose.
The disinfection method of dysentery is to use 50% of 50g of ruminant mildew and 50kg of water. After mixing, spray 1000kg of nutrient soil, mix evenly with spray and accumulate for 1 hour and then spread it on the seedbed to sow.
