Yucheng Honeysuckle is produced in Rucheng County, which is located in Dashi Mountain, and is a famous “hometown of honeysuckle” in Guangxi. The medicinal ingredients and nectar content of the honeysuckle produced in the county are high, the growth environment has no pollution source, and the chlorogenic acid content is 4.2%, far exceeding the Pharmacopoeia regulations. After the 21st century, the county changed its past to use sulfur to dry for modern dehydration treatment. Make the product a safe green drink, which is a high-quality raw material for pharmaceuticals and flower tea. It can be used as a tea to drink and taste sweet.

Honeysuckle is a unique resource in Yucheng County and has been cultivated for hundreds of years. According to Song Qingli's "Yucheng Zhi" records, honeysuckle, rich in North, Yiyi, Chengguan Shishan District, the people take medicine, stop thirst, cool off. According to the "Yucheng Literature and History Materials", from the Tang Dynasty in Zhizhou to the Yucheng County in the late Qing Dynasty, the county magistrates sent the special products "three treasures" to the provincial imperial court Wang Hou. The honeysuckle of the town, the yellow smoke of the group, and the yellow essence of the ancient canopy, there is the saying of "Gongbi Sanbao". According to Beijing (1996), archaeologists visited the site of the ancient pottery kiln near the north of the Hongshui River in Hongdu Town. In Lucheng County, as early as in the Song Dynasty, the Chaozhou pottery master of Guangdong Province set up a kiln to burn pots. At that time, the pottery and native products (such as honeysuckle, earthen, yellow, yellow, goat, etc.) were arrived in Hong Kong and Macao by the Hongshui River. Exported to Southeast Asian countries, especially in pots and pots, honey and silver flowers on behalf of tea, can cool the heat, for the use of VIPs.

Yucheng honeysuckle quality technical requirements (a) variety. Lonicera hypoglauca Miq. (2) Cultivation area. The slope is below 50°, the soil selenium content is 0.2 to 1.0 mg/kg, and the pH is between 6.0 and 7.5. (3) Cultivation techniques. 1. Selection of seedlings: use high-quality cuttings or seedlings with developed roots, no root-knot nematodes, root mites and other quarantine pests and diseases. 2. Planting density: Planting density ≤1200 plants/ha. 3. Fertilization management: Fertilization is mainly based on organic fertilizer, supplemented by chemical fertilizer. Apply the first fertilizer 40 days after planting, and apply it once a month for 4 times. After entering the second year, the farmer's fertilizer should be applied once or twice a year, that is, from the end of May to the beginning of June, the second time. It is carried out from the end of October to the beginning of November. In principle, the amount of fertilizer applied should be determined according to the factors such as the age, yield, growth, growth soil and management level of honeysuckle. As the growth and yield of honeysuckle increased, the amount of fertilizer applied increased. The young flower piers are used to produce 2 to 3.5 kg/dump of farmyard manure, and 5 to 10 kg/dm of farmyard manure are put into the production. (4) Harvesting and processing. 1. Harvesting time: In April of each year, the flower buds are rod-shaped, full, thick and thin, and the upper part is slightly enlarged when harvested. 2. Harvesting method: Select 9:13 on sunny days, avoid violent flipping when harvesting, and keep the shape and color of the flower buds. 3. Processing technology: raw flower (flowers) → screening to impurity initial inspection → loading → pre-treatment → loading dehydration special vehicle → tunnel dehydration dryer → unloading → sorting → grading packaging → storage. (5) Quality characteristics. 1. Sensory characteristics: divided into three levels: special grade, first grade and second grade. The indicators are as follows: Yucheng Honeysuckle Dry Products Grading Scale Index Safety Moisture Range (%) Color Impurity Content Needle Length (cm) Flower Bud Quality Special 10～13 green white or yellow white without impurities ≥4 flower buds openness ≤1%, neat and consistent, less curl, no broken needles level 10~13 yellowish white or golden yellow, no variegated flower needles without impurities ≥3 flower buds open Degree ≤ 3%, neat and consistent, less curl, no broken needle secondary 10 ~ 13 yellow white or yellow brown, variegated flower needle volume ≤ 3% ≤ 3% 2 ~ 3 flower bud openness ≤ 20%, neat and consistent, less Curl, the amount of broken needle ≤ 5% 2. Chemical index: moisture content ≤ 14.0%, chlorogenic acid content ≥ 4.2%. 3. Level of protection: dry product of honeysuckle above grade 2 (including secondary) that meets the above-mentioned sensory characteristics and physical and chemical indicators.
