What are the planting methods of purple leaf plum?

I. Seedling raising techniques

The seed of purple leaf plum is not easy to be collected, and cutting is a common method. Choose the sandy loam with flat terrain and deep soil layer as the seedbed. After applying organic fertilizer on the surface of the bed, rake it out and then disinfect the soil.

The main results are as follows: (1) on the adult trees with strong growth and no diseases and insect pests, the 1-2-year-old sprouts with good Lignification and full bud eyes are selected and cut into 10-16-year-old cuttings, then they are soaked with rooting powder, and then they can be cut.

(2) cutting before and after cutting the Autumn Equinox is the most suitable, which is easy to maintain moisture and is beneficial to healing and rooting. On the whole seedling bed, the cuttings were cut according to the row spacing of 15 × 25 or 5 × 8, the depth of the cuttings was 3 × 4, the buds were exposed, and the soil was firm at last.

(3) watering immediately after the management of cutting, and setting up a plastic arch shed on the seedling bed, the height of the shed is 50 ~ 80 ℃. When the temperature in the shed reaches 30 ℃, the shed is ventilated. Cover with grass curtains before winter to prevent frost damage. In March of the following year, purple leaf plums germinate and take root with the increase of temperature. We should pay attention to ventilation, loosen the soil and weed in time, fertilize and irrigate. Foliar fertilizer is sprayed every 15 days or so, nitrogen fertilizer is applied once every two months and water is thoroughly watered. The large seedlings for landscaping can be transferred to another bed, the row spacing is 40 × 50 cm, and the height of seedlings can reach 2 × 3 m after two years of cultivation. The height of the fixed stem should be about 1.5m and sprout from the branches.

II. Planting techniques

Purple leaf plums can generally be planted in courtyards, squares, lawns, streets and roads and near buildings. When the seedling is more than two meters, dig a hole of 80 × 60 × 40, transplant the seedling with soil, keep the seedling root intact and moist, and water once immediately after planting. After 2 or 3 years of planting, the inner bore branches, upper competitive branches and disease and insect branches can be trimmed in order to keep the crown compact and symmetrical.
