Botanical Information
Botanical Classification
Prunus species of the Rosaceae family, specifically the common apricot or wild apricot.
Morphological Characteristics
1. Apricot: A deciduous small tree, 4–10 m tall; bark dark reddish-brown, longitudinally fissured. Simple, alternate leaves; leaf blades rounded-ovate or broadly ovate, 5–9 cm long, 4–8 cm wide. Flowers bloom before the leaves emerge in spring; flowers are solitary at branch tips, arranged relatively densely, somewhat resembling a raceme;Flowers are nearly sessile; the calyx is tubular at the base, covered with short soft hairs on the outside, and 5-lobed at the top; there are 5 petals, white or pale pink, round to broadly obovate; numerous stamens are attached to the margin of the calyx tube; the pistil is monocarpellary and attached to the base of the calyx tube. The drupe is round, rarely obovate, with a diameter of 2.5 cm or more.Seed: 1, heart-shaped-ovate, pale red. Flowering period: March–April; fruiting period: June–July. 2.
2. Mountain Apricot: A shrub or small tree, 2–5 m tall. Leaves ovate or nearly round, (3–)5–10 cm long, (2.5–)4–7 cm wide. Flowers solitary, 1.5–2 cm in diameter;sepals oblong-elliptic, with acute tips; petals nearly round or obovate, white or pink. Fruit is flattened-globose, 1.5–2.5 cm in diameter, flattened on both sides; the flesh is thin and dry, splitting open when ripe, with a sour and astringent taste. The stone separates easily from the flesh; the base is asymmetrical on one side and smooth. Flowering period: March–April; fruiting period: June–July.
Distribution Area
1. Apricot: Distributed throughout China, mostly cultivated. Wild populations are found in the Ili region of Xinjiang. 2. Wild Apricot: Distributed in Northeast China, North China, and Gansu, among other areas.
Growth Habits
Highly adaptable, drought-tolerant, cold-hardy, tolerant of poor soils, and resistant to saline-alkali conditions. It can grow normally at summer temperatures as high as 43.9°C and overwinter safely at temperatures as low as -40°C. It can be planted on flat land or slopes and is not particular about soil type.
Propagation Methods
Propagation is by seed or grafting.
Cultivation Techniques
1. Seed Propagation: Harvest ripe fruits, rub off the pulp, and collect the seeds. Mix the seeds with moist sand at a ratio of 1:3 for winter sand stratification.Sow in late March for spring planting, or in late November for fall planting (seeds for fall planting do not require sand stratification; simply air-dry them in a well-ventilated, shaded area before sowing). Sowing is typically done in wide ridges, with one row per ridge. For spot sowing, space plants 10–15 cm apart, placing one seed per hole. After sowing, cover with 5–6 cm of soil (approximately three times the diameter of the seed) and firm the soil.
2. Grafting Propagation: Use seedling rootstocks from apricot or wild apricot seedlings. Branch grafting is performed in late March, while bud grafting is carried out from early July to late August.
Pest and Disease Control
1. Diseases include apricot leaf spot. Spray with a 5-degree lime-sulfur solution before budbreak and a 0.3-degree lime-sulfur solution when leaves unfurl.
2. Pests include the apricot weevil, as well as bagworms, longhorn beetles, and others.
