Paeonia lactiflora is a perennial herb with fleshy roots. The stems are clustered, and the height is 50 cm-100 cm. Bipinnate compound leaves, leaflets usually 3-lobed, oblong or lanceolate, with red veins. The stems are tufted with roots, about 50 ~ 1 10 cm high, herbaceous, cylindrical at the base, angular at the upper end, some twisted, some straight, and the sunny part is mostly purple.
growing environment
Paeonia lactiflora grows on hillside grasslands and forests at an altitude of 480-700 meters in the northeast, and on hillside grasslands at an altitude of 1000-2300 meters in other provinces. Paeonia lactiflora likes light and is cold-resistant, and it can survive the winter in the open field in northern China. Summer likes cold climate; Loam with deep, moist and well-drained soil layer can blossom on clay and sandy soil, but it is not suitable for growth in saline-alkali land and low-lying land. ?
distribution range
China, Korea, Japan, Mongolia and Russia (Siberia); In China, it is distributed in Jiangsu, Northeast China, North China, Shaanxi and southern Gansu, and also cultivated in parks in Sichuan, Guizhou, Anhui, Shandong, Zhejiang and other provinces and cities. ?
Key points of propagation and cultivation
The propagation is mainly based on ramets, which are carried out in autumn from 9-65438+1early October (from Bailu to Cold Dew). Burying 2 cm in soil is more suitable for cultivation. Sowing is often used in breeding and rhizome cultivation. Cold-tolerant, the north can overwinter in the open air, while the aboveground part dies in the late June of 65438+1October of 65438+1October of 065438, and grows and blooms in the following year. I like sunshine, but it's good to blossom with a little shade. I like sandy loam and good drainage, so low-lying and saline-alkali land are not suitable for planting.
