1. Cutting propagation

The advantage of this simple method is that it is most successful in daily life. For propagation in this way, it is best to use a new basin with a diameter of 20 cm for cutting, and the material should be tile basin. Because this kind of basin has good air permeability, it is easier to grow roots. It is most suitable for cutting in spring and autumn. The temperature of about 23 ℃ is conducive to survival. Before cutting, it is necessary to spray the soil in the flowerpot one day in advance, but it should not be too wet. It is appropriate that the soil is just wet during cutting. The depth inserted in the soil is 3-4 cm. After cutting, the basin should be covered with plastic bags, and the bag mouth should be tied tightly. When watering, open the plastic bag and tie it again after watering

2. Strip breeding

① High technology is generally used for strip pressing. Banding is often carried out in April and may. First of all, take the healthy and strong branches that are 2-3 years old from the mother plant, and cut off a circle of branch skin about 1 cm wide with a knife at about 10 cm above the branches. Then wrap the branches loosely with a rectangular plastic film, tie them with a rope at about 2 cm below the lower end of the branch incision, open the upper end of the plastic film in a trumpet shape, and then fill in the soil from the upper end

② In case of water shortage, water can be sprayed on the leaves to let the water flow down the branches and slowly penetrate into the soil, maintain the humidity of the soil, accelerate the healing of the wounds on the branches and let it grow new roots. When the root grows 3 cm long after 3 months, it can be separated from the mother plant

3. Sowing and breeding

Most varieties can be bred by sowing. The maturity period of seeds is from October to January every year. When the peel color changes from cyan to yellow and finally to brown, the upper part of the fruit will crack and the seeds begin to scatter. At this time, the seeds can be collected. Generally, sowing is carried out in March and April, and sowing is carried out in the basin. Because the seeds are small, the basin should be cleaned and dried, and the basin and soil should be disinfected
