High-yield cultivation techniques of Flos Lonicerae

Honeysuckle, alias Erhua, Shuanhua, honeysuckle, Suhua, honeysuckle and so on. With unopened buds for medicinal use, it has the effect of clearing heat and detoxification, dispelling wind and detumescence. It mainly treats wind-hot cold, sore throat, pneumonia, dysentery, pain, sores, erysipelas, cellulitis and other diseases. Honeysuckle vine is used as medicine, which has the effect of clearing heat and detoxification, dredging channels and activating collaterals. It mainly treats damp fever, joint pain, pain, sores and ulcers, urticaria, mumps, bacillary dysentery and so on. The main producing areas are Shandong, Henan and other provinces.

The morphological characteristics are perennial shrubs of honeysuckle family. Stems slender, hollow, much branched, young branches densely pubescent, green or brown. Leaves opposite, ovate or long ovate, entire, densely pubescent. Flowers are axillary in pairs, silvery white at first, golden yellow after 2 or 3 days, fragrant, 3-5 cm long; 2 leafy green bracts at the base of the petiole, calyx short, light green, 5-lobed, lobes triangular, hairy, Corolla tube, apex lip-shaped, upper lip 3-lobed upward; Corolla tube slender, densely pilose. Stamens 5, yellow. One pistil, style slender and stamens protruding from the Corolla tube. Ovary inferior, glabrous, subglobose. Berries globose, 3-4 mm in diam., mature black.

Red glandular honeysuckle is a perennial climbing shrub with leaves ovate to ovate-shaped with dense microhairs and orange-red glandular hairs under the leaves. Corolla 3.5-4.5 cm long, berries, black when ripe.

Honeysuckle is a perennial vine, the branches are yellowish brown and gradually turn white. Leaves ovoid to elliptic, main veins shortly sparsely hairy, densely white pubescent below. Stamens 5, pistil 1, style linear, bald. Berries, black when ripe.

Hairy style honeysuckle is a perennial vine, style more or less hairy.

First, the growth habits of honeysuckle prefer a warm, humid, sunny climate. Strong adaptability, drought resistance, cold resistance, waterlogging resistance. Soil requirements are not strict, barren mountains, houses in front of the house, riverside roadside, can be planted, but with deep soil layer, loose and fertile sandy loam rich in organic matter is better.

Second, select fields with high terrain and good drainage for soil preparation and fertilization, and cultivate them carefully. Combined with soil preparation, apply sufficient basic fertilizer: 3000 kg of soil miscellaneous fertilizer, 20 kg of urea and 50 kg of phosphorus and potassium fertilizer per mu. Then make beds and wait for sowing.

Third, sowing honeysuckle is mainly by cutting propagation, and it can also be divided into root propagation and strip propagation. The sowing time is spring, summer and autumn. Cutting propagation selected 1 ~ 2 years of robust branches, cut into 30 cm long cuttings, every 50 into a bundle. After soaking the lower end in the rooting powder solution for 10 seconds, the lower end can be cut on the finished border surface according to the row spacing of 15 X 5 cm and watered to preserve soil moisture in order to survive. The annual branches near the ground were selected from the plants that had flowered for 3 ~ 4 years in winter and autumn, and were bent and buried in the soil, the part of which was burnt, watered and rooted, and then cut off from the mother plant in the next spring and planted separately. After transplanting in the spring and autumn season, the honeysuckle seedlings were planted on the finished border surface according to the row spacing of 1.5 × 1.2 cm, and watered to preserve soil moisture in order to survive.

After honeysuckle survives, attention should be paid to ploughing and weeding. Water immediately in dry weather. Attention should be paid to drainage in cloudy and rainy weather. After germination and after each bud harvest in spring every year, fertilizer was topdressing once, 10 kg of urea and 5 kg of potassium dihydrogen phosphate each time. Spread a layer of soil fertilizer in winter. At the same time, pruning should be carried out in the process of growth. The branches are trimmed into corymbose shrub-shaped flower stumps with sparse branches, uniform distribution, ventilation and light transmission, stout trunk and upright.

The main disease of honeysuckle is powdery mildew, which can be controlled by strychnine at the initial stage of the disease. The main pest is longicorn beetle, which can be sprayed with 50% phoxim during the peak spawning period.

6. harvesting and processing honeysuckle is generally picked in mid-and late May, when the buds change from green to white, the upper part is enlarged and the lower part is blue. The buds are removed when the dew is not dry in the morning, and dried or dried in time, which can be sold as medicine. Harvest four crops a year. The yield is 150 kg per mu.
