Prunus tomentosa is a shrub, usually 0.3- 1 m high, and it is sparse in the shape of a small tree, which can reach 2-3 meters high. Branchlets are purplish brown or grayish brown, and shoots are densely tomentose to glabrous. Winter buds ovate, sparsely pubescent or glabrous.
Extended data:
After harvesting small cherry in Northeast China, the peel and pulp were cut to take out the stone, and the pulp except the stone was washed with clear water, and then the cherry was dried in the shade 1-2 days before sowing. When sowing, the seeds are directly sown in shallow pots, and germinate about 10-30 days after sowing.
When the seedling grows to 5- 10 cm, transplant it into a plastic soft pot. Cherry seeds germinate easily, but their germination is irregular, and the seeds produced by some plants often lack viable embryos, and the germination rate is often lower than 30%. The fruiting age of seedling method is late, and the quality variation between seedlings is great.
July-August is the concentrated period of cherry flower bud differentiation. Through reasonable tree structure, ventilation and light transmission are increased, and the photosynthetic efficiency of leaves is improved. The balance between vegetative growth and reproductive growth is regulated by technical measures such as pulling branches and opening angles, pinching, twisting tips and moderate drought, so as to provide sufficient nutrition for flower bud differentiation.
