Therefore, the sandy loam soil with deep soil layer, loose soil and good drainage should be selected when planting, and the land must be sunny sloping land, not shady land, so as to avoid poor growth and development due to lack of light.

Before sowing, we should choose a seedling land, which also requires loose and fertile soil and good drainage. At the same time, we should plough the soil and apply base fertilizer to prepare for sowing. Black plum is usually sown in April in spring, and the sowing time can be chosen according to local climate change, soil and production purpose. When sowing, we should pay attention to the sowing density, not too dense, and it is suitable for the density to keep the plant row spacing 20 × 7 cm. After sowing, cover a layer of fine soil of about 3 cm and cover it flat.

When the young tree grows to about 1 meter, its top tip should be cut off, and among the branches that germinate again in the following year, 3-4 branches should be selected as the main treatment, radiating around or even. Until the third year, select 3-4 strong branches on the main branch as the secondary main branch, and then leave 3-4 strong branches on the secondary main branch. After 3-4 years of pruning, a complete happy crown will be formed. at the same time, winter and spring pruning will be carried out every year to trim off disease and insect branches, dense branches, overgrown branches and weak branches.

Bordeaux solution can be sprayed at the initial stage of the disease, once every 7-10 days, 2-3 times in a row, the effect is better.
