Budding technique of Old Reed head of potted Orchid

When the potted orchid propagates to a large number, it will produce an old Reed head. If the old Reed head is full and full, there are generally several latent buds in the upper part that have not yet sprouted. As long as the old Reed head is peeled off from the original clump and planted for careful maintenance, the probability of new dormant buds is very high. These old Reed heads can be used as materials for breeding new orchid plants. as long as measures are taken to promote leaf buds, they will become a treasure and improve the reproduction rate. The method of budding is as follows.

1. Suitable plant material, layered basin

The bottom of the orchid basin is filled with larger particles of plastic foam as the bottom material, which is filled with a mixture of 60% shiitake soil and 40% grain shell carbon, which is about 2max 3 of the height of the basin. Fill it with pure river sand without salt or limestone. The old Reed head is planted in the river sand, and the river sand is properly covered with water moss. In the process of maintenance, keep the basin soil moist but not wet, spray 0.2% potassium dihydrogen phosphate every 7 days, and sprout more than a month after planting. The best time for planting old Reed head is in December in winter.

Selecting these plant materials to layer the upper basin has many advantages: first, Lentinus edodes soil and grain husk charcoal have the properties of both water benefit and water retention, which will inevitably cause the orchid root to rot if they are placed in the middle and lower part of the orchid basin. Lentinus edodes soil contains nutrients, and grain husk charcoal mainly contains potassium (lifa root). Nutrients can be obtained when the new roots of new buds germinated after old Reed head planting extend to the mixed layer of Lentinus edodes soil and husk charcoal. When the new seedlings are planted in the original pot, there is no need to plant them, and when they are propagated to 2-3 clumps, they will be replanted. In this way, the relatively weak new seedlings can be prevented from "dying" due to premature transplantation. Second, planting orchid in river sand is beneficial to promote root and bud, but the effect of river sand is not ideal because it does not contain nutrients, has no microlarvae, and has poor ability of absorbing fertilizer, keeping moisture and keeping fat. On the other hand, the layered upper pot method with Lentinus edodes soil and grain shell charcoal to supply the orchid plant nutrients and covered with water moss can give better play to the advantages of river sand promoting root and bud.

two。 Reasonable shallow planting, proper shading

The old Reed head must be planted shallowly, because the latent bud eyes of the old Reed head which have not yet germinated are mostly growing in the middle and upper part of the Reed head. If planted deeply, the new buds germinated are easy to rot. The suitable planting depth is 1-1-3-1-2. The light should not be too strong, too strong is not conducive to germination, but it is appropriate to accept some scattered light or reflected light, which is beneficial to the germination of new buds as soon as possible.
