How to Sow Prunus triloba Seeds
For most women, an introduction to how to sow Prunus triloba seeds and the planting methods and requirements of this green plant and flower, let's learn about them together below.
Prunus triloba belongs to the Rosaceae peach genus shrub, with a height of 2-3 meters; also known as Ulmi Pruni, Small Peach Red, Ulmi Pruni Branch, etc. It is named because its leaves resemble those of Ulmus and its flowers look similar to plum blossoms. Prunus triloba has lush branches and leaves, with colorful and beautiful flowers, making it suitable for cultivation in park lawns, roadsides, or corners of gardens and pondsides. It has high ornamental value and can also be used as a potted plant or cut flower. Prunus triloba is the main flowering wood for spring viewing in the northern regions, similar to Prunus persica nucipersica, blooming before leaves with dense flowers on the branches.
Prunus triloba is native to North and Northeast China, liking sunlight, slightly shade-tolerant, cold-resistant, and capable of surviving winter at -35℃. It is not strict with soil requirements, with neutral to slightly alkaline and fertile soil being optimal. It has a developed root system, strong drought resistance, does not tolerate waterlogging, and has strong disease resistance. It grows in low to medium altitude slopes or沟旁 forests of trees or shrubs, or on forest edges.
The leaves on short branches of Prunus triloba often cluster together, while the leaves on one-year-old branches are alternate; the leaves are broadly elliptical to obovate, 2-6 cm long, 1.5-3 (4) cm wide, with a short acuminate apex, often 3-lobed, a broad cuneate base, sparsely pubescent or hairless on the upper surface, and pubescent on the lower surface, with coarse or double serrated edges; petioles are 5-10 mm long, pubescent. Flowers are 1-2, opening before leaves, 2-3 cm in diameter; pedicels are 4-8 mm long; calyx tubes are broadly campanulate, 3-5 mm long, hairless or slightly pubescent when young; sepals are ovate or ovate-lanceolate, hairless, with sparse small serrations near the apex; petals are nearly circular or broadly obovate, 6-10 mm long, rounded at the apex, sometimes slightly concave, pink; there are about 25-30 stamens, shorter than the petals; the ovary is densely pubescent, and the style is slightly longer than the stamens.
I. Propagation Methods of Prunus triloba: The propagation methods of Prunus triloba include seed propagation and grafting. Since seed propagation cannot maintain the original characteristics of the variety and may result in some reverting to single-petal flowers, reducing ornamental value, grafting is a better method. The rootstock for grafting uses single-petal Prunus triloba, Prunus davidiana, or Prunus persica nucipersica seedlings. The rootstock generally needs to be cultivated for more than two years, with a base diameter of about 1.5 cm, and should be cut off in advance before grafting, retaining a tree stump 5 to 7 cm above the ground surface. Bud grafting is done from late August to mid-September, while branch grafting is performed in mid-to-late March. Branch grafts can bloom the following year, while summer bud grafts bloom in the third year, and seed propagation blooms completely in the third year.
II. Cultivation and Management: Prunus triloba prefers a cool climate, is cold-resistant, drought-resistant, and thin-soil-tolerant, and not strict with soil requirements. It grows well in deep, fertile, loose sandy loam and slightly acidic soil rich in humus. The cultivation and management of Prunus triloba are relatively relaxed, as long as attention is paid to pruning the rootstock suckers at any time, updating the branches after flowering, cutting off the branches after flowering to promote the germination of new branches (since the flower buds of Prunus triloba are all on new branches), not updating old branches that have weak growth and few and thin flower buds, resulting in fewer flowers the following year. After pruning, appropriate fertilization should be applied, and watering should be paid attention to, to promote the robust growth of new branches. Fertilize once before summer bud differentiation and before winter. After early spring flowering and leaf expansion, when Prunus triloba has consumed a lot of nutrients, top-dressing at this time is very beneficial for the post-flowering growth of the plant, making it grow vigorously with lush branches and leaves. From June to September in summer and autumn is its flower bud differentiation period, during which a moderate amount of phosphorus and potassium fertilizers should be applied.
Prunus triloba is prone to leaf-eating pests such as刺蛾,舟形毛虫, and 饺子虫, as well as aphid damage to new shoots in summer, which can be controlled by spraying with 1500 times the concentration of carbaryl or 1% tobacco water.
