The author explored the method of rapid propagation by dividing plants, and each plant with good vitality can germinate four or five new buds every year. This method won the Bronze Award for Science and Technology and the Paper Award, and was included in China Orchid Collection and China Orchid Atlas respectively. Now it is briefly introduced as follows: 1. Create conditions, enhance the accumulation of organic matter, improve the vitality of meristem, and lay a good foundation for rapid tillering and reproduction. Its specific practices can be summarized as follows: planting loam with six sides facing the sky, being dry and suitable for humidity, often sheltered by frost and rain, avoiding pollution sources as far as possible, fully illuminating in winter and spring, shading in summer and autumn, preventing and controlling pests and diseases as soon as possible, supplying fertilizer as needed, removing scabs as soon as possible, and supplementing nutrients after flowering. Second, separate plants in autumn to promote their meristematic growth: in order to appreciate flowers, three or four generations should be planted together, but the plants planted together are interdependent, and the individual meristematic ability is not strong, so only new plants can tiller naturally. If they are dismantled, dispersed and forced to stand on their own feet, meristems will flourish and the germination rate will be high. However, it is often because the original growth ability of plants is not strong, and it is easy to tear the base of bulbs when disassembling, which leads to stem rot, and the new plants that wither and germinate have only two leaves and grow slowly. Therefore, it is suggested to separate the two plants into a group, and the two plants should be separated slightly. When disassembling the plant, we should pay attention to exerting force on the bulb of the old plant, cut the connector with a disinfection knife, then cut off the dead roots, broken roots and diseased leaves, plant them in new blue soil, manage them at constant temperature for one month, and then raise them normally. Apply more cooked and ground bone powder and spray potassium dihydrogen phosphate 800 ~ 1000 times a week. When the temperature will rise in spring, spray one of "Love and Harvest", "Yigaoling", "Ye Bao Mian", "Yihuabao" or germination promoter with 1000 ~ 1500 times solution every week, and apply alternately. And give more light (or light simulation light), pay attention to heat preservation. Only in this way can we achieve a gratifying germination rate.
