Both sowing and ramets can be propagated. Sowing requires a complete set of equipment and technology. Generally, the production unit uses multiple plants for breeding. The methods are as follows:
1. Paste tree method. In the early spring or in the fall, the broad-leaved trees with thick trunks and more water are selected, such as eucalyptus, nanmu, maple, gingko, and pear trees. Select the densely-dense, root-rich, stem-greenish Dendrobium plant clusters, cut dry stems, broken branches, and old stems, cut the long fibrous roots to a half, and cut large pebbles, leaving 4-5 strains of leaves in each bundle. Stem, select the trunk or depression in the trunk with a knife to cut a shallow crack (sometimes not cut), the base of the Dendrobium plant cluster close to the cut at the mouth, with 1-3 bamboo nails nailed, if the posted trunk is more convex The site is first cut with a knife and then nailed, or it can be tied with bamboo sticks or ropes. Decayed branches and bark cannot be planted. After fixing, mix the fertilizer with bean dregs, cake flour and other fertilizers, mix it with the bark root and the bark around the root (should not be stuck on the stem base of Dendrobium) for growth. The number of plants to be planted depends on the size of the trunk and the number of branches, and each tree can be planted in several bundles to dozens of bundles.
2. Shade planting method. Choose a cool, damp place and build a rectangular sorghum 16cm high with masonry or stone to prevent rain from scouring the soil. Use coke ash and fine sand to mix well, fill in the pot, make the soil fine and level, place a 1.3-1.6-meter-high shed on the urn, hang a straw curtain on the south side of the shed to prevent sun exposure, and then use the stone rake to use the former method. The ramets were planted in a pot and covered with 0.5-1 cm thick sand and pebbles.
In order to speed up the breeding, you can also plant the sarcophagus by planting 15-20 centimeters from the planting distance. Only the tip is exposed on the soil surface. After germinating new shoots and white air roots on the stem section, dig out the horizontal raft and press it with small stones. Soil surface, covered with fine soil about 1 cm, when the new plant grows 6-10 cm high, it can be divided transplantation.
3. Pot propagation method. Cut out the pseudobulbs with more than 4 latent buds, flatten the wounds, smear them with sulfur powder, and then plant them in pots to keep them moist.
In addition, the aerial stems of Dendrobium are very long, and new plants can be grown from the stem sections. They have both stems and leaves and roots, and they can be cut in sections to plant another pot. It is also possible to use the stem segments of the non-occurring small plant clusters for cutting propagation. Put them into marl and maintain high temperature and high humidity, and soon rooted leaves.
