1、 Strip pressing operation

It is usually striped from May to July every year. This time has high temperature and humidity, so it is the best time. The specific method is as follows: select an appropriate position at the stem of the plant to cut into a ring. When cutting, the width of the ring mouth should be about 2 cm and the depth should reach the wooden position. At this time, first cut off the skin of the ring mouth with a knife, then wipe off the external liquid with a clean wet cloth, and apply 5000-1000ppm naphthylacetic acid aqueous solution on the skin of the incision, then tie it with white plastic film at the lower end of the incision, straighten it out and make it into a funnel, and then install the rooting stem made of mountain soil and moss. Wrap the knife edge, and then pour water once to tighten the upper end of the river membrane, At this time, the plant should be maintained outdoors to strengthen its fertilizer and water management. Generally, after 30-40 days of cultivation, new roots will appear at the circumscribed part. They can be cut off from the mother from September to October and transplanted to other places to become new plants and grow healthily

2、 Cutting method

The method of cutting propagation is generally carried out from May to June. This period is the vigorous growth period of long Xuelan. At this time, its body is rich in nutrition, so it is easy to survive. Before cutting, we should choose the one with high ornamental value and strong branches that grow for more than two years. Each section of it is about 10-20 cm long. When cutting, its base should be cut into a flat mouth, and the leaves should be retained after the upper part is cut horizontally. After the spilled juice can be washed with clean water at the upper and lower cuts, it should be placed in a cool and ventilated place for a period of time, and then soak the base of the cutting with 500-1000ppm naphthylacetic acid for 2-3cm for 5 seconds. It should be soaked and inserted at the same time. For the cutting of long Xuelan, a smaller earthenware flowerpot can be used, and the matrix used can be perlite or sterilized sand. Cutting can be carried out after the pot is put on. Plant one plant in a pot, water it once after completion, and then place the seedbed in a sunny place for careful maintenance. About two months later, the cultivated soil can be used for pot transplanting
