Preparation before cutting

Nutrient soil, river sand, peat soil and other materials for special cutting can be used. It is recommended to use the prepared and detoxified cutting matrix for family cutting, and medium coarse river sand can also be used

The substrate should be washed with clean water several times before use. Sea sand and river sand in saline alkali areas should not be used because it is not suitable for the growth of flowers and plants

Selection of cutting branches

The selection of cutting branches is usually combined with the work of coring, taking the picked thick, disease-free top tip as the cuttings, and directly cutting with the top tip

Management after cutting

The most suitable temperature for cuttings rooting is 18 ℃ - 25 ℃. If it is lower than 18 ℃, cuttings rooting is difficult and slow. If it is higher than 25 ℃, cuttings are easy to be infected by bacteria and rot, and the higher the temperature, the greater the proportion of rot

when cutting at low temperature, the main measure of heat preservation is to wrap the flower pot or container that is used for cuttings. If the temperature is too high, we need to shade the shading, cover up 50% to 80% of the sunshine, and give the spray 3 to 5 times a day. p>

After cutting, the relative humidity of the air must be kept at 75% - 85%. Spraying can increase humidity by 1 days to 3 times per day. The higher the temperature is, the more the number of sprays will be. The lower the temperature is, the less the time will be. p>

Cutting propagation is inseparable from sunlight, but the stronger the light, the higher the temperature in the cuttings, the stronger the transpiration of cuttings and the more water consumed, which is not conducive to the survival of cuttings

Therefore, 50% - 80% of the sunlight must be covered after cutting. After the root system grows, the shading net shall be removed gradually. It shall be removed at 4 pm every day on sunny days, and covered before 9 am the next day
