Timely removal of diseases with one dose of orchid in summer

In summer, flower lovers who raise orchids must feel very difficult, because in this hot and humid season, orchids not only grow poorly, but also easily suffer from diseases. What are we going to do with this? It's all right, the editor tells you, with this "one dose", the orchid disease can be removed in time.

This "dose" is potassium permanganate solution. It is a strong oxidant, commonly known as PP powder, is a common surgical disinfectant for people and animals, and it is also a common drug without pollution. Potassium permanganate solution has strong sterilization, disinfection and antiseptic effect, and it is also widely used in plants.

In summer, potassium permanganate solution has a significant effect on controlling many diseases of orchids, such as sudden drop disease, standing blight, downy mildew, soft rot, Fusarium wilt, root rot, virus disease and so on. At the same time, potassium permanganate solution contains essential manganese and potassium nutrients for plants, which can promote the growth of orchids, which can be said to be both medicine and fertilizer.

In addition, if you usually maintain orchids and need to replenish nutrients to orchids, it is recommended that flower friends use special organic nutrient solution for orchids, diluted 500 times, once a week, directly irrigate the roots of orchids, which can meet the three elements of nitrogen, phosphorus and potassium needed for the growth of orchids.

Next, let's take a look at the main role of potassium permanganate solution in controlling orchid diseases and insect pests:

1. Prevention and treatment of sudden fall disease and blight disease

Potassium permanganate solution has a very significant control effect on the quenching disease and root rot of new orchid seedlings. After the leaf buds of orchids are unearthed, they can be sprayed or irrigated with 800-1000 times (dilute first and then concentrated) once every 10 days.

2. prevention and control of soft rot

Potassium permanganate solution also has a good effect on the prevention and treatment of soft rot of orchids. In the hot and humid environment in summer, the new orchid seedlings are easy to suffer from soft rot. Flower friends can spray the leaves with 800-1000 times diluent before the disease to prevent and cure it.

In the early stage of the disease, the diseased seedlings can be removed from the basin, cleaned, soaked in 600 times diluent for half an hour, then taken out, dried the orchid root and then put on the basin. The soaking solution is used to irrigate the root water, which can have a good therapeutic effect.

3. Disinfection of pots and plants

Pots and plant materials, especially reused old pots and coarse plant materials (such as rough pond cornerstone, gold plant stone, coarse immortal soil, etc.), immediately soak in 800 times potassium permanganate solution for 1 hour or 2 hours after sieving and rinsing the fine soil, can kill the germs in the old basin tools and old plant materials, so as to prevent the bacteria from spreading again when the old basin tools and old plant materials are used again.
