Matrix of Prunus pumila cutting

It is difficult to obtain ideal cutting matrix for family cutting. It is recommended to use prepared and detoxified cutting matrix, including medium coarse river sand, but wash it with clean water several times before use

Sea sand and river sand in saline alkali areas should not be used. They are not suitable for the growth of flowers and plants

Cutting steps of elm leaf plum

If the twigs born in the current year are selected, the thick branches born in the current year shall be selected as cuttings when the plants grow vigorously from late spring to early autumn

After cutting off the branches, select the strong part and cut it into a section 5-15 cm long, with more than 3 leaf nodes in each section

When cutting cuttings, it should be noted that the upper cut is about 1 cm above the top leaf node, the lower cut is about 0.5 cm below the bottom leaf node, and the upper and lower cut should be flat

If the old branches born last year are selected, after the temperature rises in early spring, the robust branches of last year are selected as cuttings, and 3-4 nodes are usually reserved for each cuttings

Management of Prunus pumila after cutting

The suitable temperature for cuttings rooting is 20 ℃ - 30 ℃. If it is lower than 20 ℃, cuttings rooting is difficult. If it is higher than 30 ℃, cuttings are easy to be infected by bacteria and rot. the higher the temperature, the greater the proportion of rot

After cutting, the relative humidity of the air must be kept at 75% - 85%. The basic requirement of cuttings rooting is to ensure that the cuttings are fresh and tender before rooting, and photosynthesis can be carried out to produce rooting materials

After cutting, the sunlight must be covered by 50% - 80%. After the roots grow, the shading net shall be removed gradually. In sunny days, the shading net shall be removed at 4 pm every day, and the shading net shall be covered before 9 am the next day
