It takes several years to raise seedlings of Cycas in Guangshui area. If planted with old stems, it will take several years to induce the growth of sucking buds, and the yield is very limited. In mass production, it is necessary to introduce more than 20 cm cycad blanks from Fujian, Guangdong, Yunnan and Guizhou and make them on the spot. The method is as follows: In early spring, soak the cycad blank in potassium permanganate disinfectant for about half an hour, take it out, dry the surface moisture, cut off a layer of old stems at the top with a sharp knife to make the incision smooth, seal it with yellow clay and a little sulfur powder, then cut off the old skin at the root to expose new stubble, and seal it with sulfur powder or charcoal powder. Then mix the pure coarse sand and vermiculite evenly, and the depth is equivalent to 1/4 stem length. The top of the plant can be covered with a layer of cattail, which is not only sunshade and breathable, but also warm and moist, which is beneficial to wound healing and bud germination. After planting neatly, put them on a warm, moist, ventilated, rain-proof and cool scaffolding in batches. Always keep the basin moist, not dry, not wet. When a number of leaf buds grow, plant them in loose and fertile slightly acidic sandy soil rich in humus, shape them in time, and carefully maintain and manage them. You can see the benefits in three years.
