Judge the situation of Langen by the focal point

Some Lanyou have a headache on the focal point, and the cause is very complicated, which may be caused by excessive dryness or fertilization, bruise infection, and root rot. Once the focal point occurs, it is indelible! The common method is to take leaf cutting (until the green part), jump, piercing and other methods to control. Interested orchid friends might as well try the half-fold method, that is, fold in half at the green edge of the focal point to block the water supply and curb the expansion of the focal tip. When folding in half, you can sometimes hear the sound of breaking, which shows that the focal tip is caused by overdryness. if there is no sound, there is water seeping out of the fold, which may be too wet or fat (the fat wound is cooked at first, and then the infection spreads). The problem can be found through half-fold inspection, so that we can prescribe the right medicine and deal with it. This is much more fun than just cutting it off!

In addition, the focal tip part is treated by the folding method, and there is another judgment function: to observe the development of the focal tip and disease spot in the upper and lower position of the folding line. In general, 3Mel can be found in 5 days: the upper part of the broken line is dried, from dark brown to yellowish brown and whitening, and the focus no longer appears in the lower part of the broken line, which shows that the focal tip is infected with fungi after physical injury, and the development of the focal tip can be controlled by blocking moisture, and then cut off the whitening part. If the focus continues to occur in the lower part of the folded line, and after folding down again, dark-brown disease spots still appear in the lower part of the folded line, at this time, it should be suspected that there are pathogens invading the root and transported to the folded line wound, showing the expansion of the disease. It is suggested that in this case, the root should be checked until the pot is turned over and replanted!

Prevent coke tip, mainly control the dry humidity of plant material, plant formula should pay attention to permeability! Fertilizer must not be too thick, at least more than 1/1000, or even a little more light! At the same time to maintain orchid ventilation and a certain degree of environmental humidity! If focal points and disease spots occur, you can use the above methods to deal with them! You can try!
