Propagation of orchids

There are two methods for the reproduction of orchids: root splitting and sowing. Because sowing is very difficult, to have a certain technical level, so it is common to use the root-splitting method to reproduce. Today, they are briefly described as follows: (1) Root-splitting propagation is also called "split-planting", or "turning basin", which is a more complicated item in Yilan technology. 1. The most appropriate time for root separation is around April or September, that is, around the Qingming Festival and the Autumn Equinox (the basin mud must be slightly drier when turning the pot, and if the wet mud is turned over, the root is easy to break and hurt) 2. The mother plant should first choose a strong and disease-free mother plant, and pay attention to the four or five leaves of Chunlan and the eight or nine leaves of Cymbidium. An orchid can be divided only if it has 30 or 40 leaves. In general, orchids are divided into roots every two or three years, and it is not appropriate to divide more. The new leaves are not easy to grow, and the newly turned basin soil cannot be firm for a while. Once the rain is drenched, floating mud touches the leaves, which often causes diseases. 3. After the mother plant is selected by root cutting, the orchid plant can be gently turned out from the basin, the mud can be removed, and the abortive root and residual leaves can be carefully repaired with small scissors. When pruning, scissors should be used horizontally, not vertically, so as not to hurt the buds. After pruning, wash the root with falling water (that is, the stored Rain Water), put it in a cool place, and wait for the root color to turn white and show a dry state before it can be cut into a basin. If the weather is wet, the sun should be exposed for more than ten minutes after the root is semi-dry, and then dry. After the root is dry, you can choose the middle space (commonly known as "road") and cut it quickly. If you find that there are many old roots, you should also cut off a few branches so as not to hinder the development of new roots. 4. After the upper pot root has been cut, it should be put on the pot. There must be a hole at the bottom of the basin for ventilation and discharge, and several layers of clam shells must be covered on the hole, overlapping alternately, so as to form a conical shape. Other tiles, such as tiles, can also be used, but the weight is too heavy to move and is not suitable. In case the hole is too large, thick lead wire can be used to make a conical net, about 7cm high, and then covered with a layer of brown wire, so that it can be used for more than a decade without being bad; there are also sharp hat-shaped nets made of bamboo wire, which can only be used for about a year. After the clam shell and brown net are put in place, it must be tight, and then fill it with coarse sand around the clam shell, about 1 cm thick. On the top of the coarse sand, but also add coarse mud or fine mud, the thickness should be based on the size of the plant root system and the depth of the basin as the standard, generally Chunlan can fill 5 cm, Cymbidium can fill about 3 cm, and press the central part of the soil surface with your hand to make it protruding like a bristle. When the filling is finished, the langen which has been cut from the ribbon is put into the basin, and the root is fixed, leaving it in a natural state. Once again, fill it with fine mud around the basin until it is about 2-3 cm near the mouth of the basin. At the same time, lift the plant up a little bit. When pressing the mud, you should use your fingers to pick the mud into the root from all sides, so that the root can touch the soil without leaving any gap. Therefore, it is required that the soil of the root is very solid and will not sink, but the soil on the edge of the basin might as well be looser. At this time, it is also necessary to cover the basin with plants such as green cloud grass as grass protection. Orchids on the pot, to be fully watered, placed in the north of the shade, about half a month to a month or so, do not make contact with the sun, it is easy to send roots to survive. When the soil of the basin becomes more and more solid and the green grass has survived, the orchid basin can be moved outside. In order to keep Orchid Hui strong and have a certain developmental ability, the newly leafy grasses, regardless of Chunlan, Cymbidium and Jianlan, generally do not use this method of turning pots, as long as they use the raw mud in other pots to cover pots every one or two years. It is easier to promote flowering. The method of covering pots: orchids are usually cultivated in pots of three different sizes according to the size of their roots. The initial root-splitting plants generally use pots with a caliber of about 15 cm, and then put them into pots with a caliber of about 22 cm and 27 cm after growing up, while large clusters of orchids can be inserted into large pots with a caliber of about 40 cm. When setting the basin, first press the soil on the edge of the basin with the right hand for several times, then hold down the topsoil of the basin with the left hand, pour the basin down, and push the soil in the basin around the clam shell with the right thumb, so that the soil of the plant can be poured out from the original basin. After the plant is poured out, all the soil must be put into the new basin intact, and finally around the original mud, add new culture soil, and plant Cuiyun grass, compacted and watered. Although orchids are potted flowers, they can also be directly planted and propagated in the open field after root separation.
