Detailed Explanation of Orchid Propagation Methods and Techniques

1. Create favorable conditions, enhance the accumulation of organic matter, increase meristem vitality, and lay a solid foundation for rapid tillering propagation. The specific practices can be summarized as: plant in loam with the pseudobulbs exposed, ensure air circulation on all six sides, keep slightly dry while maintaining appropriate humidity, diligently provide shelter from frost and rain, strenuously avoid pollution sources, provide full sunlight in winter and spring, provide half shade in summer and autumn, prevent and control pests and diseases early, apply fertilizers according to need, remove flower spikes early, and supplement complete nutrients after flowering.

2. Divide and scatter-plant in cool autumn to promote tillering: To enjoy the flowers, it is necessary to plant three or four generations together, but when planted together the plants depend on each other, the individual tillering capacity is not strong, and only new plants can tiller naturally. If they are separated and scatter-planted, forcing them to stand on their own, the tillering capacity will become vigorous and the germination rate will be high. However, when divided into single plants for scatter-planting, often because the original growth vigor of the plants is not strong, tearing easily occurs at the base of the pseudobulbs during division, leading to stem rot and death, and the new shoots that sprout have only two leaves and grow slowly. For this reason, it is recommended to divide two plants into one group, with the two plants slightly separated but not completely detached. When dividing the plants, attention should be paid to applying force toward the pseudobulbs of the old plants, and the connecting tissue should be cut apart with a sterilized knife, then withered roots, broken roots, and diseased leaves should be trimmed off, and the plants should be put into fresh orchid potting mix, managed at constant temperature for one month, and then cultivated normally. Apply more burned and crushed bone meal, and spray 800 to 1000 times diluted potassium dihydrogen phosphate solution weekly. When spring temperatures are about to rise, spray or water weekly with 1000 to 1500 times dilution of one of the following: "Yiduoshou", "Gaochangling", "Yemianbao", "Huabao", or a germination promoter, used alternately. Also provide more light (or simulated light from lamps), and pay attention to keeping warm. In this way, a gratifying germination rate can be achieved.
