Cuttage is generally carried out in early spring or early summer. The branches and twigs of last year are taken as cuttings. The cuttings are required to be 10-15 cm long with 2-3 nodes.
Basin soil generally requires loose, fertile, well drained and humus rich soil, which can be mixed with garden soil, rotten leaf soil and rotten chicken manure in the proportion of 6:3:0.5.
First wet the seedbed to avoid damaging the cuttings.
Put the cuttings in the shade and air dry. When the cut milk is completely dry, insert it into the sand bed. The cuttings can be cut into the soil at a certain depth, otherwise the survival rate is relatively low.
After inserting, water shall be poured in time to make the cuttings close to the soil.
It can take root in 45-50 days under the condition of 20 ℃, and can be transplanted after taking root.
After cutting, before spraying the cuttings, spray evaporation should be used to reduce the moisture evaporation of the cuttings. Spraying under the shading conditions, 2 to 3 times a day.
In rainy days, the lower the temperature, the fewer times of spraying, or choose not to spray.
To control the amount of spray, excessive spray will cause the cuttings to be infected by bacteria and rot.
The most suitable temperature for the growth of yellow cicada is 20 ℃ - 30 ℃, lower than 20 ℃. The cuttings grow slowly and difficultly. Therefore, if the temperature is low after cutting, the flower pot or container with cuttings can be wrapped with film for heat preservation.
After cutting, if the temperature is higher, the cuttings are susceptible to infection and rot. Therefore, shading should be shaded by 50% to 80%.
The cuttings can not be separated from sunlight after cutting, but the stronger the light, the higher the temperature in the cuttings, the more vigorous the transpiration of cuttings, and the more water consumption, which is not conducive to the survival of cuttings.
After cutting, the shading must be 50% - 80%. After the root system grows, turn over the shading net.
