Seeing the title, some flower friends may ask, "what is orchid laolutou?" In fact, orchid laolutou is generally referred to as old orchid bulbs with roots and leaves, leaves and roots or no roots and leaves. Most of these bulbs are peeled off when turning the pot, which should be thrown away. However, the more valuable orchid laolutou might as well make use of it to make the dormant buds on laolutou germinate again, so as to cultivate new orchids. It is also a way to improve the germination rate of orchids. Now let's take a look at the specific processing method:
How to deal with orchid laolutou
1. Time: at the end of spring and the beginning of summer, when the daytime temperature is above 15oC.
2. Prune the old reed head. After removing the unhealthy reed head, take 2-3 reed heads as a clump, remove the rotten roots and dead leaves, and pay attention not to damage the bud eyes.
3. Soaking disinfection: soak the old reed head in 1000 times methylthiophanate solution for 10 minutes, and take it out to dry.
4. The diluted germinating agent was dropped on the corm and dried for planting.
5. Soak the root promoting solution with sterilized water moss and wrap the old reed head.
6. Put it into the basin, fill with planting stone around, and bury the bulb into the depth of 1-2 cm, and keep it in a cool and ventilated place.
7. Normal watering should not be too dry or too wet, and fertilizer should not be used. New buds can sprout after 20 days. Some sprouting time may be a little later, so be patient to wait.
8. After the new buds are put into leaves, they can be put into the ventilated and transparent place, and gradually receive the light. Don't apply fertilizer to root system, but apply fertilizer to leaf surface. It's better to use thin, thin and light fertilizer. Otherwise, burn new roots and leaves, and the gain will not be worth the loss.
9. In the spring of the next year, the orchid plants were taken out and the rotten old bulbs were removed, which could be cultivated and managed normally like other orchid plants.
It must be noted that the orchid plants obtained by this method are small seedlings and weak grass after all, which are only suitable for the reproduction of rare orchids for seed reservation, and there is no need to fight against ordinary orchids.
