1, check the leaves: this fake method includes rubbing or even scraping the edges or raised veins of the leaves, causing certain damage, and even drawing lines on the leaves with pigments; Or pretend that orchids with poor growth or even diseased spots are "exotic leaves" or "spotted" plants. The method of cracking is to carefully check whether the leaves are intact, whether there is dirt pollution, whether the patches or yellow parts can still carry out photosynthesis, and whether they are healthy and shiny. Otherwise, it is suspected that the leaves are fake and pretend to be famous orchids;
2. Flower inspection: This fake method is to cut the flowers of rare orchid varieties, insert them in the reeds of ordinary orchids or between two leaves, and fix them with glue. Or inject chemicals into the orchid reed head to make it bloom white flowers. The reed head of this orchid usually rots. Only through careful observation can we see whether we can find subtle clues;
3. Look at the roots: cut the roots of other orchids into the roots of rare orchids that are disabled and rootless, and pretend to be healthy and precious orchids for normal sale;
