Propagation methods of Cymbidium grandiflora

Cymbidium can generally be propagated by ramet method, and it is a suitable time for ramet when new buds begin to sprout in spring. The new plant after ramet should have more than 3 pseudobulbs. After cutting and waiting for the wound to dry, the normal plant can split once every 3 years. The tool should be disinfected when ramet, so as not to cause virus infection. The potted Cymbidium should be placed in a warm and humid environment until the new buds protrude from the soil and can be managed according to the normal method.

Specific methods:

Take the sturdy plant out of the basin, cut it off from the junction of the pseudocorm with a sharp knife and cut it into several clumps, each with 2 or 3 pseudocorms (one of which must be newly formed in the previous year). Smear the incision with sulfur powder or charcoal powder in time, put the new plant in a dry place and dry for 1 or 2 days, then put it into the basin separately. The suitable time for ramet is after the flower fade to before the new bud grows. If possible, aseptic sowing, fertilized embryo culture, tissue culture and other methods can be used for mass propagation. Note that the false corms must all be exposed to the surface of the culture soil. Put it in the half-shade and half-sun place after planting, because the cultivated soil is wet, so avoid watering within 1 week after planting, only spray water on the leaf surface (usually spray 4-6 times a day), and gradually turn to normal maintenance after 1 week.

In general, the propagation method of Cymbidium is the main points of plant reproduction:

1. The timing of ramet is the short dormancy period after flowering and before the new bud grows.

2. Ramet is carried out when the root of the plant is slightly whitish, soft and dry.

3. Robust plants can be divided once in 2-3 years, and the cut orchid seedlings should have 2-3 pseudobulbs in each clump.

4. Smear sulfur powder or carbon powder on the wound of the plant to avoid infection

5. After placing the orchid seedlings in a dry place for 1-2 days, they can be potted alone and propagated successfully.

Matters needing attention for ramet propagation:

The main results are as follows: 1. Cymbidium should be placed in the semi-shade after splitting.

2. Cannot be watered immediately. If the basin soil is found to be too dry, you can spray a small amount of water to the page and basin surface.

3. The new bud base can not be watered normally until the new root grows.

4. Observe the health of the plant to avoid the phenomenon of leaf drying, shedding and pseudo-bulb shrinkage (rehydration).
