Orchids suffer from root rot

When the orchid suffers from root rot, it greatly reduces the role of absorbing and transporting water and nutrients, and the pathogen will spread to the whole plant along the dredging tissue, hindering the applied growth and reproductive growth, and even lead to plant death. The treatment of root rot of orchids should focus on prevention, and the specific operations are as follows:

1. The seedlings should be strictly disinfected, the cultivation medium should be relatively thick and disinfected, the upper basin should be standardized, the cultivation container should be high and there should be many holes.

two。 Timely and appropriate amount of watering and fertilization; timely and effective heat preservation and anti-freezing, cooling and moisturizing, maintaining air circulation; timely and reasonable supply of nutrition.

3. Enhance immunity. Spray with aspirin 1000-1500 times solution in spring, summer and autumn every year.

4. Timely treatment. When it is found that there are black rot, soft rot, white silk disease, bacterial wilt and other diseases on the leaf surface, the fungicides such as carbendazim, carbendazim, dioxone, Kesong, streptomycin, aluminophosphate, chloramphenicol and penicillin are sprayed and irrigated in time. Once a week, the concentration of chloramphenicol and penicillin is 1000 times, and that of chloramphenicol and penicillin is 3000 times.
