Cutting is generally carried out from April to July, and the temperature is about 15-20 ℃.
It is difficult for families to get the ideal cutting medium because the cutting medium needs to keep water and water. Here we can buy the cutting medium that has been configured. It's OK to use medium coarse river sand, but it needs to be rinsed with clear water several times before use, and it's better to disinfect it. Do not use the river sand in the saline alkali area, which is not suitable for the growth of flowers and plants.
Cutting is generally carried out in combination with coring, and the top shoots with strong growth and without diseases and insect pests are selected as cutting ears.
The rooting temperature of Nanking cherry is 18-25 ℃. When the temperature is lower than 18 ℃, the rooting is slow. When the temperature is higher than 25 ℃, the scissor of cuttings is easy to be infected and rotted by pathogens, and the higher the temperature is, the greater the rotten is. If you encounter low temperature during cutting, you can pick up the cutting flowerpot or container with film. When the temperature is too high, it should be shaded. Put cuttings in a cool place and spray them regularly.
After cutting, it is necessary to keep a high air humidity, and the relative humidity is generally maintained at 75-80%. Spray can be sprayed every day, 1-3 times a day. When the temperature is high, spray times increase. Be careful not to spray too much. The cuttings are susceptible to infection by bacteria in the water and rot.
However, 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, it is necessary to cover 50-80% of the sunlight after cutting, and gradually remove the shading net after the root system grows: remove the shading net at 4:00 p.m. every day in sunny days, and cover the shading net before 9:00 a.m. the next day.
