The latest method of cultivation of pearl plum

Pearl plum is not called mountain sorghum stripe, Gaokaizi, eight articles, etc., it is a shrub plant of the genus Prunus in Rosaceae, named for its color like pearl, with high ornamental value, elegant in beauty, proud in frost and snow, in the autumn when thousands of flowers wither and sand is serious, only its branches stand out and become a beautiful symbol of strength and courage to struggle with difficulties. let's take a look at the breeding method of Pearl Plum.

Growth habits of Pearl Plum

Pearl plum is born in sparse forests on hillsides, 250-1500 meters above sea level, and is distributed in Hebei, Jiangsu, Shanxi, Shandong, Henan, Shaanxi, Gansu, Inner Mongolia and other places in China. Resistant to cold, half shade and pruning. It grows better in sandy loam with good drainage. It grows fast and is easy to sprout.

The Propagation method of Pearl Plum

1. Ramet: Pearl plum is easy to germinate roots and tillers, so it can be propagated in March and April in early spring. Dig up the soil around the root of the mother plant that is more than 5 years old, cut down from the middle of the gap, separate the tiller from the mother plant, and divide it into 5 to 7 plants per plant, and the isolated root tiller seedlings should have complete roots. After ramet, pour enough water, and move the plant into a slightly shaded place, gradually put in the sun for normal maintenance a week later.

2. Cutting can be carried out all the year round, and the cuttings in March and October have the fastest rooting and the highest survival rate. Cuttings select mature branches on robust plants, cut and grow 15 to 20 centimeters, leaving 4 to 5 buds or leaves. When the cuttings are cut into the soil, only one or two buds or leaves at the top of the cuttings are left on the soil and watered once. After that, spray water 1 or 2 times a day, often keep the soil moist, reduce the number of water spraying after 20 days, and take root and transplant in about 1 month.

3. Striping: Pearl plum striping propagation usually bends and presses the outer branches of the mother plant directly into the soil in March and April, and can also cut or cut the part of the pressed soil in order to promote rapid rooting. After the new root is grown, it can be separated from the mother plant and transplant in spring and autumn.

Culture method of Pearl Plum

1. Soil: Pearl plum is not strict with the soil, but it grows better and blossoms more luxuriantly when cultivated in deep and fertile sandy soil.

2. Watering: Pearl plum should be watered in time during spring drought and thoroughly watered in summer and autumn to keep the soil from drought, and anti-freezing water should be watered once before winter.

3. Light: Pearl plum can bear half shade, but it is also good to grow in the sun.

4. Fertilization: Pearl plum does not have high requirements for fertilization. When it is just cultivated, it needs to apply enough base fertilizer to meet its growth requirements, and generally no longer apply topdressing. In the future, combined with winter management, base fertilizer can be applied every 1-2 years.

5. Pruning: after pearl plum blossom, the residual flower branches, disease and insect branches and old and weak branches should be pruned in time to keep the plant type neat, avoid nutrient consumption, and promote its strong growth and luxuriant flowers.

6. Diseases: the main diseases of Pearl Plum are leaf spot, powdery mildew, brown spot, and the main pests are beetles, spotted leaf wax cicada and so on. Early prevention and control should be achieved to promote the healthy growth of plants.

Points for attention of Pearl Plum

The main results are as follows: 1. Pearl plum has strong adaptability and does not have high requirements for fertilizer. except for a small amount of base fertilizer for newly planted plants, it does not need rotating fertilizer, but it needs watering. Generally, it is watered 2-3 times during the period from leaf bud germination to flowering, and the Beginning of Autumn is watered 2-3 times from post-frost to frost, including anti-freezing water, watering in summer depending on drought, and no need to water when it rains a lot.

2. The inflorescence of pearl plum blossom is withered and yellow, which affects its appearance, so the residual inflorescence should be cut off to make the plant clean and tidy, and avoid the residual inflorescence competing with the plant for nutrients and water. Diseases and insect pests and old and weak branches should also be cut off after autumn or early spring, and annual branches can be strongly pruned to promote the renewal of branches and the flourishing of flowers and leaves.

3. Pearl plum should remove the diseased and residual plants in late autumn, reduce the source of pathogens, pay attention to ventilation, reduce the air humidity, strengthen the light, increase the application of phosphorus and potassium fertilizer, enhance the resistance, cut off the damaged parts in time, or remove the diseased plants to burn and spray. Spray the same amount of 1% Bordeaux solution during dormancy, and spray 70% methyl topiramate 800 times or 50% Dysenamine 800 times 1000 times at the initial stage of the disease.

4. Spraying Zhuangtiling at the bud stage of pearl plum can promote strong buds, enlarged petals, bright color and rich fragrance. After falling flowers, the residual flower branches, disease and insect branches and old and weak branches should be pruned in time to keep the plant type neat, avoid nutrient consumption, and ensure healthy growth and luxuriant flowers and leaves in the coming year.
