Disinfection of granular plant materials

The plant material of orchid is also the breeding ground and umbrella of orchid disease. For example, white silk disease and brown rot are caused by plant infection. The disease is the most dangerous, so far there is no drug that can really subdue it, and the only way is to prevent it and avoid infection and disease. Therefore, plant disinfection is a very important part of raising orchids. At the beginning of raising orchids, the author had a heavy lesson that the whole army was wiped out. To this day, he still has lingering fears and is cautious step by step. Nowadays, granular plant material is widely used in orchids, which has the advantages of cleanliness, ventilation and hydrophobicity, which is disadvantageous to the pathogen, but it is not foolproof. In fact, granular plant material used for a long time, will also produce bacteria and viruses, harmful to the orchid strain. The author raised orchid all the use of granular plant materials, and in a closed balcony such an excellent environment, in theory, it is best, but there is still brown rot. The reason is that the replaced plant material is reused without disinfection.

Plant disinfection generally has steam disinfection, daylight disinfection, drug disinfection. Steam disinfection effect is good, but very troublesome, often give up because of trouble; sunlight and drug disinfection is more convenient, but not thorough, it is inevitable that there are pathogens to survive. Now the author adopts the steam disinfection method with sunlight as heat energy, which is convenient and reliable. The specific operation is as follows: the granular plant material replaced by turning the basin is packed in a large plastic bag and can be disinfected when it is hot in summer. Spray it into the plastic bag first

Sheung Shui moistens the plant material, tightens the mouth of the bag (no air leakage) and places it on the cement floor in the sun. The water in the bag evaporates into steam when heated, and the temperature is so high that it can kill all the pathogens in the plant material in two or three hours. Lan you might as well have a try.
