Honeysuckle is a commonly used Chinese medicine for clearing away heat and toxic materials, and chlorogenic acid is its main effective component. The sequence of chlorogenic acid content is Sanqing > Erbai > Dabai > Branches and Leaves > Jinhua > Yin Hua. The export of its high-quality products has been in short supply. Location: Shandong, Henan and other provinces. Among them, the quality of "Nanyinhua" produced in Henan is better; It is famous for its large number of "East Silver Flowers" produced in Shandong. Now it is cultivated all over the country. [Morphology] Perennial semi-evergreen twining small shrubs or erect small shrubs. It can be as long as 9 meters. The stems are thin, hollow and multi-branched, and the young branches are green; Dense pilosity; Old branches fall off and the skin is brown and striped. The leaves are opposite, and the winter does not fall, hence the name "Lonicera japonica"; Leaf blade ovoid or elliptic, entire; Flowers are born in the axils of leaves, so they are also called "two flowers" and "double flowers"; Corolla slightly lipped, tube and petals nearly equal length, style and stamens longer than corolla, fragrant. Flowers are white at first, and then turn golden yellow, so they are also called honeysuckle. Berries come in pairs and are black and shiny when ripe. The flowering period is from April to June, and the fruiting period is from June to September. [Habits] I like warm and humid climate, and I have strong adaptability, and I can also tolerate cold, drought and waterlogging. It can be cultivated in all parts of China, including mountains, plains and hills. The requirements for soil are not strict, and sandy loam with loose soil, fertile soil and good drainage is better. Saline-alkali tolerance, suitable for growth in alkaline soil. Deep roots can prevent soil erosion and can be planted on barren slopes. Honeysuckle is a sunny crop. Most of the flowers are born on the sunny new branches, with lush foliage, which is easy to cause depression; Therefore, only through pruning and fertilizer and water management can high yield be obtained in cultivation. Honeysuckle variety resources: Honeysuckle likes warm and humid climate, and the suitable growth temperature is 20℃ ~ 30℃, with high humidity and strong air permeability as the best. As long as there is a certain humidity all year round and the temperature is generally not lower than 5℃, it can germinate, and the number of buds germinated in spring is the most. Developed root system, many fine roots and strong rooting ability. Under suitable temperature and humidity, cuttings and drooping branches can take root in less than 15 days. 10 annual plant, the root cap distribution diameter can reach 300-500 cm, the root depth 150-200 cm, and the main root system distribution 10. Most fibrous roots grow in 5 ~ 30cm topsoil. Roots grow fastest from the beginning of April to the end of August. Like long sunshine, insufficient light will affect the photosynthesis of plants, with slender branches, small leaves, stronger entanglement and less bud differentiation. Flowers mostly grow on sunny branches and are suitable for planting in sunny and well-ventilated places. The requirements for soil are not strict, but it is planted in loose, fertile and deep soil, with developed roots, good growth and high yield. Too much soil moisture will affect growth, leaves will turn yellow and fall off easily. Honeysuckle resources. Variety resources of honeysuckle in Sichuan.
