Propagation method of Broussonetia papyrifera: cutting propagation

Cutting methods are divided into hard branch cutting and tender branch cutting. The survival rate of softwood cutting is high, so this method is widely used. The specific cutting methods are divided into two kinds: shade cutting and full light fog cutting

Shade cutting

It is generally carried out in summer. Semi lignified green branches are used as cuttings under the shade. The cuttings are 6cm-15cm long, with bud eyes and leaves reserved, and branches with 2-4 sisters. Shallow cuttings are recommended, and the depth is about one third of the length of cuttings. Spray water frequently after cutting, but do not spray too much water. The cuttings shall be protected from sun exposure and sun shading. The cuttings can be ventilated for 4-5 days, and the covering shall be gradually uncovered after half a month. Pay attention to ventilation and light transmission intensity after rooting

All light fog cutting seedling

The cutting time is from June to August. The matrix can be river sand, perlite or prepared from peat, perlite and vermiculite in a certain proportion. The cutting method is roughly the same as that in the shade

Propagation method of Broussonetia papyrifera: grafting propagation

The survival rate of bud grafting and branch grafting is very high. Select suitable tree species for grafting. Branch grafting is carried out in spring, and the grafting position is about 2-3cm away from the ground. Budding was carried out in summer and autumn, and the grafting height was less than 8cm. Tie tightly with plastic film, remove the sprouts on the rootstock in time in the future, and remove the plastic film after full healing
