Reproduction and production of Flos Lonicerae

Honeysuckle is a perennial semi-evergreen shrub. Honeysuckle stem hollow, much branched, leaves opposite, creeping tufted, flowers in pairs axillary, Corolla tube-shaped, white at first, then golden yellow and fragrant. The full flowering period is 5 to 20 years, and the annual florescence is from June to August, which is mainly concentrated in about 20 days after Xiaoman, and the fruit matures from August to October. Honeysuckle has strong adaptability and can grow on slightly acidic, alkaline and saline soil. It has developed root system and strong drought resistance. In the summer of 2001, in the producing area of Honeysuckle in Linyi City, Shandong Province, there was no dripping rain for three months, and the grains of summer corn were not picked up, but the yield of dried honeysuckle exceeded 1.5 million kg. Honeysuckle is suitable for cultivation in vast areas of China, and it is distributed in 12O0 counties of 27 provinces, municipalities and autonomous regions in China. Linyi City, Shandong Province is the main producing area of honeysuckle. In 1998, the dry flower yield of honeysuckle reached 2 million kg.

Honeysuckle has a strong ability of asexual reproduction, so cutting seedlings can be raised at an average temperature of more than 5 ℃. Select 1-2-year-old strong branches as cuttings, cut into 16 to 18 cm, according to plant spacing 2 cm, row spacing 20 cm, 166000 plants / mu density cutting, cover soil with just exposed a pair of buds, and then steadily irrigate. A month later, topdressing 2 to 3 times, applying urea 5 to 7.5 kg per mu, waiting for 15 to 20 cm of new shoots to pick the heart and promote new branches, so that 3 to 4 times in a row, each plant can have 4 to 8 branches, then it can be transplanted out of the nursery.

At present, the main varieties cultivated are big hairy flower, chicken claw flower, goose feather tube, thread flower son, needle flower son, pair flower son, Ye Li Qi and so on. The main planting methods are Weir planting and field planting. When honeysuckle is planted in the field, the establishment of dense planting high-yield garden can make full use of space and solar energy. Dense planting high-yield gardens should generally choose sandy soil with flat terrain, thick soil layer and good drainage. The land should be leveled first, with a depth of 60 to 80 cm, 5000 kg of miscellaneous fertilizer per mu and 50 kg of ammonia bicarbonate per mu. The barren land should be planted according to the pier spacing of 1 × 1 m, 3 to 5 plants / pier, 667 piers / mu, and fertile soil should be planted at the density of 0.5 × 0.75m, 1776 piers / mu. It can be planted every spring, summer and autumn.

After the establishment of the dense planting high-yield garden of honeysuckle planted in spring, there is generally a profit in the same year, and management must be strengthened in order to achieve high yield. deep turning, hole expansion and pier cleaning should be carried out in combination with fertilization every winter and spring, and topdressing 2 to 3 times in summer. and watering and drainage. At the same time, attention should be paid to shaping and pruning, cutting off senescent branches, over-dense branches and long-growing skills in winter or early spring, so as to concentrate nutrients on the flower branches, so that the pier type gradually forms a natural round or umbrella-shaped and other high-yielding pier.

Flowering management should pay attention to diseases and insect pests, 40% omethoate EC can be used to control aphids; powdery mildew can be sprayed with 75% chlorothalonil wettable powder 2000 times, or powder powder can be used, and the effect is very good. After the above management measures, three crops of flowers can be picked every year.

Honeysuckle processing and storage is very simple, the collected flowers will be evenly scattered by hand on the Reed mat or cleaned ground to dry, should not be turned, to 80% dry can be accumulated.

Once dried honeysuckle, after a period of time to dry again 1 to 3 times, so that it does not contain water, and then put into a plastic bag and fasten the mouth of the bag, properly preserved for sale.
