Picking and processing skills of Flos Lonicerae

1. The time of picking flowers: the time of picking flowers is from 9 to 12:00 last year, which is not suitable for picking when there is dew and rainy days, and can also be picked if there is drying equipment. The green flower picked in the morning has the advantages of heavy white, easy drying, strong aroma, high commodity rate and good quality. The quality of flowers picked after noon and in cloudy days is poor, and the processing rate is low. From the process of flower development, the habit can be divided into green buds, green and white, large white needles, honeysuckle and golden flower wilting flowers. The upper part of the bud is enlarged and grows into a rod, which is better when it is bluish white, which is commonly known as the big white needle. At this time, the flowers are about to open, for the best picking time, high-quality goods can be processed. 2. Picking methods: use bamboo baskets or rattan cages when picking, do not use cloth bags and plastic (11180, 55.00, 55.00, 0.49%) bags and cartons, to prevent heat and dampness, enzyme and protein fermentation in the body, discoloration and mildew. Flower buds and flower tissue are very tender, must be picked gently, do not use hand stroking tight pressure, so as not to affect the quality. 3. Drying: drying immediately after harvest and drying on a sunny day. Use bamboo foil or straw mat to spread out to dry, the thickness is 1 cm, can not turn more. Put it in a bright place to dissipate heat and sweat when it is 70% dry, and then dry it again. So that the flowers do not become brittle and shabby. Dry at a mild temperature on cloudy and rainy days, first bake at 35 ℃-40 ℃ for 2 ℃ for 3 hours, and then rise to 50 ℃ to 9% dry without damage. Drying rooms should be built in large planting area and producing areas to strictly prevent mildew and improve the quality of goods. In general, 7 kilograms of dried flowers and 1 kilogram of goods. 4, processing grading: processing must start from flower picking and drying, it is best to dry separately according to quality, pick out impurities at any time, and produce more first-class goods. The national standard of honeysuckle commodities is divided into four grades. First-class: dry goods, buds are bracing, thick and thin, slightly curved, green and white on the surface, Corolla thick and hard, holding it with a top feel; fragrance, sweet and bitter taste. Open flowers, broken buds and yellow strips not more than 5%. No black stripes, blackheads, branches and leaves, impurities, moths, mildew; second-class: basically the same as first-class, but blooming flowers do not exceed 5%. Broken buds and yellow strips do not exceed 10%; third-class: dry, buds are rod-shaped, thick and thin, slightly curved, green-white or yellow-white on the surface, Corolla thick and hard, with a top feel. The breath is fragrant, and the taste is sweet and bitter. Bloom flowers, blackheads no more than 30%. No branches and leaves, impurities, moth, mildew; fourth class: dry goods. The bud or the open flower has both colors and lustre. No more than 3% of branches and leaves, no impurities, moths, mildew. Recently, the goods are tight and sell well, generally more processing for mixing and so on. However, the cultivation should pay attention to the quality, take the production quality management standard of traditional Chinese medicine (GAP) as the principle, build the industrialization base, create authentic famous brand goods, and improve the reputation and benefit.
