The ramets of Cymbidium houmianensis should be thawed in early spring, i.e. from February to March.
Take the mother plant out of the flowerpot, shake off the extra pot soil, and separate the coiled roots as much as possible. Use a sharp knife to cut it into two or more plants, each of which should have a corresponding root system, and properly trim its leaves to facilitate survival.
Soak the separated small strain in the solution 1500 times of chlorothalonil for five minutes, then take it out to cool and dry, and then put it into the basin. You can also fill the root with chlorothalonil immediately after serving.
After being potted in individual plants, the roots are irrigated or the water is permeable once. Because its root system is greatly damaged and its water absorption ability is very weak, it takes about 3~4 weeks to restore the new root. Therefore, it is necessary to control the watering in the 3~4 weeks after the ramets, so as to avoid root rot, but its transpiration is not affected. In order to maintain the water balance of the leaves, it needs to spray 1~3 times to the foliage every day (high temperature, multiple spray, low temperature, little spray or no spray). Don't fatten up at this time. After branching, we should also pay attention to the strong sunlight, and it is better to put it in the shade shed for maintenance.
When the seedlings are loaded into the basin, first put 2-2cm thick coarse-grained matrix or ceramsite at the bottom of the basin as the filtering layer, sprinkle a layer of fully decomposed organic fertilizer as the base fertilizer, with a thickness of about 1cm-2cm, and then cover a layer of matrix, with a thickness of about 1cm-2cm, and then put the plants to separate the fertilizer and the root system, so as to avoid burning the root.
The following peat + perlite + ceramsite = 2 parts + 2 parts + 1 part peat + slag + ceramsite = 2 parts + 2 parts + 1 part sawdust + vermiculite + medium coarse river sand = 2 parts + 2 parts + 1 part. After the basin is poured, it will be watered once, and placed in a slightly shaded environment for maintenance for a week.
When transplanting small seedlings, dig the planting hole first, sprinkle a layer of organic fertilizer (base fertilizer) on the bottom of the planting hole as the base fertilizer, with a thickness of about 4-6cm, and then cover with a layer of soil and put it into the seedlings, so as to separate the fertilizer and the root system and avoid burning the root.
