morphological character
Tall herbs or subshrubs, up to 3m in height. The stem is ribbed with white pith. The leaves are odd pinnate. Leaves opposite; stipules small, linear or glandular; leaflets 5-9, the uppermost pair of leaflets, the base of each other, sometimes connected with the terminal leaflets, leaflets lanceolate, 5-15cm long, 2-4cm wide, apex long and acuminate, base obtuse, both sides often asymmetric, margin serrate, near the base or below the middle edge often 1 or several remote teeth; petiole short. Large compound corymb terminal; pedicels and pedicels glabrous to more or less hairy at all levels, with yellow cup-shaped glands from sterile flowers; bracts and bracteoles linear to linear lanceolate, 4-5mm long; flowers small, calyx tube cup-shaped, about 1.5mm long, calyx teeth triangular, about 0.5mm long; corolla radial, corolla tube about 1 mm long, corolla lobes ovate, about 2 mm long, reflexed; anthers yellow or purple; anthers yellow or purple Ovary 3-locular, style very short, stigma 3-lobed. Berry: red fruit, subglobose, 3-4mm in diameter; 2-3 nuclei, ovate, about 2.5mm long, with small verrucous protuberances on the surface. The flowering period is from April to May and the fruiting period is from August to September.
Growth environment
It likes cloudy and humid environment, and has no strict requirements on soil. It can be planted in front of the house, behind the house, on the side of the land and on the hillside.
Distribution range
Distributed in Hebei, Shaanxi, Gansu, Qinghai, Jiangsu, Anhui, Zhejiang, Jiangxi, Fujian, Taiwan, Hubei, Hunan, Guangdong, Guangxi, Sichuan, Guizhou, Yunnan and other places.
cultivation techniques
Methods of reproduction
It mainly propagates by dividing roots. In the middle of February, dig up the underground rhizome, select the thick (about 5 cm in diameter) with buds, and fry it into 10-20 cm long root segment for standby. According to the ditch distance of 24-33cm and the ditch depth of 10cm, the horizontal ditch is formed, and then the root section is horizontally pressed in the ditch, covered with garbage mud and burnt mud ash, and then covered with soil for compaction.
Field management
After the emergence of seedlings, pig manure or human manure should be applied once, and appropriate weeding and soil loosening should be carried out.
Harvesting and storage
Harvest in summer and autumn, cut into sections, use fresh or dry.
chemical composition
It contains chlorogenic acid, α - amynpalmitate, ursolic acid, β - sitosterol, stigmasterol, brassinosterol, potassium nitrate, flavonoids and tannins. There are flavonoids, phenolic components, tannins, sugars, chlorogenic acid in the whole plant, and cyanosides in the seeds.
Character characteristics
The stem is columnar and stout, branched and about 1cm in diameter. The surface is gray to grayish black. Young branch compound leaves, 2-3 pairs of leaflets, alternate or opposite; leaflets to paper, easy to break, more wrinkled, flattened after a narrow ovate to ovate lanceolate, apex long acuminate, base blunt round, unequal sides, edge serrate. Fresh leaves smell when kneaded. The taste is slightly bitter. It is better to have tender stem, many leaves and green color.
Growth law
It is a perennial shrub like herb of loniceraceae, up to 3m in height. Rhizome transverse, cylindrical, yellow white, rooting on node. The stem is longitudinally ribbed, the young branches are hairy, and the pith is white. Pinnate compound leaves opposite, oblong lanceolate, apex acuminate, base oblique, slightly round to broadly cuneate, margin with dense sharp serrate, kneaded with air, corymb terminal; 5 pieces; stamen stigma capitate or 3-lobed. Berry shaped drupe ovate, red to black at maturity, with protuberances on the surface of the nucleus. The flowering period is from April to May and the fruiting period is from August to September. It grows on hillsides, roadsides, streams, and in the wild shrubs. annual shrubby herb with undeveloped inverted cup-shaped fleshy flowers, corolla lobes and stigmas capitate or 3-lobed. Berry shaped drupe ovate with protuberant surface. It can be planted in front of the house, behind the house, on the side of the land and on the hillside. Lateral veins, 4-7 pairs, slightly raised below, flat above, petiole 2-8 mm long, puberulent or glabrous; stipules membranous, ovate, apical awn pointed, 3-4 mm long, glabrescent. Flowers solitary or 2-3 clustered on top of lateral short branches with leaves and suppression, pedicel 2-5 mm long, covered with brown villous; calyx tube campanulate or ovate, 3.5-7 mm long, 4-5.5 mm wide, outer villous, eaves slightly enlarged, apical 5-lobed, lobes broadly elliptic, apical pointed, poorly growing. There are certain requirements, but it is not resistant to sunlight. In summer and autumn, there should be shade or shade to block the hot sun, and water should be often sprayed on the ground. generally in spring and autumn, mainly in spring shoots. The optimum temperature for growth is 20 ℃. When the temperature is higher than 30 ℃ or lower than 5 ℃, the growth will stop. In winter, it has a short dormancy period, and then gradually expands with the rise of temperature. Generally, it blooms from March to may in open field cultivation, and it blooms from July to August in high altitude area. North 5-8 mm long, 3-6 mm wide, with 3 veins, outside is brown villous, inside is short bristle; at the beginning of flower, outside is densely sericeous, corolla tube is wide, about 5 mm long, throat is sparsely villous, corolla lobes 5, ovate or ovate oblong, 6-10 mm long, about 5.5 mm wide, mainly by rooting. It can be used to control the tree shape and rejuvenate the tree. Generally, the new shoots are pruned before May, and the buds can be formed in the same year. If it is too late, the flowering will be affected. Generally, if the new shoots germinate too late in autumn, they are vulnerable to freezing injury in winter. Evergreen or deciduous shrubs. Dig up the underground rhizome and select the thick 10-20cm long root segment for standby. Cover with mud and then cover with soil for compaction. Leaves tend to be papery, with tender stems and more leaves.
