Prunus of Rosaceae is a small deciduous tree with a height of 8 meters. The leaves are ovoid to ovoid-elliptic, 7~ 12cm long, with a sharp tip and a round base.
Breeding method:
The layering propagation methods of cherry rootstock seedlings in layering seedling production mainly include vertical layering and horizontal layering.
1, also known as buried layering, is a widely used method in cherry rootstock propagation. In early spring, ditch first, with the row spacing of 60 ~ 70cm, the depth of 20cm and the width of 20cm, and then plant the excellent 1 annual rootstock.
2. Vertical stratification: before the soil is frozen in autumn or after the soil is thawed in early spring, the cherry rootstock seedlings are planted in the breeding nursery. When planting rootstock seedlings, ditches should be dug according to the row spacing of about 65438 0 meters.
