Marigold is prone to decay and hard to survive in the cutting propagation process. After several years of exploration, the author summarized the following experiences for reference. 1. Matrix preparation. The matrix is ​​made of 40% hull ash and 60% river sand. The hull ash not only looses drainage, but also effectively prevents the decay of the cuttings. After the matrix is ​​well-mixed, water is sprayed in an appropriate amount to make the matrix water content about 60%, and spray water for one hour before use. 2. Cutting preparation. The cuttage of marigold is usually from May to August. At this time, cuttings from marigold trimmed can be used for cuttings. Generally, they remain between 3 and 5 knots, with or without apical buds. The blades at the base of the cuttings should be pruned to avoid losing too much moisture. When cutting, the wound must be smooth, the cut of the lower cut of the cutting (slope 45), and the upper cut flat. 3. Cuttings. First, a small wooden stick of the size of the cuttings is used to make a hole in the substrate with a spacing of 3 cm and a spacing of 5 cm. When inserting the cuttings, gently insert the cuttings into the holes that have been punched in advance. The depth is 1/3 of the cuttings. Use the index finger and the thumb to slightly tighten the sandpit around the cuttings. After the cutting is done, use a sprayer to spray the wet leaves. Excessive moisture can easily cause the cuttings to rot. Then cover the net above the height of 80 cm. Spray the fog once every morning at around 10:00 and 5:00 PM. It is appropriate to spray wet blades. Another thing to note is that the place where the cutting board is placed should not be rained and cannot be photographed by the sun. Otherwise, all efforts will be abandoned. If the shading net density is not too large, it is best to cover two shading nets.
