Cultivation method of Medicinal Flos Lonicerae

Honeysuckle is a perennial evergreen vine, which has a variety of medicinal values. To cultivate medicinal honeysuckle, the following points should be done well:

The main results are as follows: 1. Selecting a good variety for medicinal use requires strong branches, reasonable structure, multiple flowering times, large number of flowers, high quality and high yield. Such as chicken claw flower and big hair flower are better medicinal varieties.

2. The sandy loam land with open ground, loose soil layer, convenient drainage and irrigation and rich humus should be selected as the planting garden, and sporadic plots such as the front and back of the house, the edge of the gully and the pond can also be used to deeply turn and improve the soil. 50 piculs of farm manure per mu is applied to form a 1.2-meter-wide border.

3. To cultivate strong seedlings, honeysuckle is mainly propagated by cutting, selecting cuttings with 1-4 buds before sprouting in early spring, removing the lower leaves, cutting along with cutting on the prepared seedbed, shading and watering, spraying water in the morning and evening in the dry season, watering according to the soil condition during the day, gradually removing the sunshade after cutting roots and long leaves, and watering 1-2% diluted organic fertilizer every other month. With the growth of seedlings, the concentration of fertilizer should be increased, and it can be transplanted to the field after half a year.

4. Scientific management fertilization is carried out before the germination of plants in early spring or before the cold wave in early winter. A trench or annular ditch was opened next to the plant, and 10 kg of rotten organic fertilizer, 0.1 kg of ammonium sulfate and 0.1 kg of calcium superphosphate were applied to each plant. The growth of seedlings was accelerated by topdressing rotten rarefied organic fertilizer and water for 2-3 times from May to June. In order to increase the number of flower stubbles, improve flower quality and yield, adult plants can also be sprayed with 0.5-1% potassium dihydrogen phosphate at the flower bud differentiation stage of each stubble. The ideal plant shape of medicinal honeysuckle is a small umbrella shrub with short and erect branches. This must be achieved through pruning. The specific method is to cut off the upper part of the trunk at a height of 30 cm, promote the bud germination under the shearing mouth into branches, retain 4-5 branches with uniform distribution and similar thickness, and then cut off the upper half of branches at all levels, and comprehensively clear the garden before sprouting every spring, cut off withered old branches, rotten branches, thin and weak branches, shade branches, roots and tillers, and centrally destroy them to reduce the source of disease and the number of insect population. The main pests of honeysuckle are aphids and coffee tiger longicorn beetles. the former harms leaves and buds and should be controlled in time. The latter uses larvae to eat the xylem of the vine stem, resulting in a hole in the trunk. The control method is to carry out artificial hook killing in the larval stage, or to plug the hole with cotton balls soaked in dichlorvos solution, and then seal it with mud. the disease is mainly honeysuckle brown spot disease, which usually occurs seriously in summer, resulting in brown spot necrosis of leaves. Jinggangmycin spray was used in the early stage of the disease.

5. The medicinal parts of harvesting and processing honeysuckle are mainly flowers. When harvesting, we should look at both the flowers and the weather, so as to pick them at the right time. When the base of the flower is turquoise, the top is milky white, the color is bright and bright, it is the best sign for picking flowers, pick them when the dew is not dry on a sunny day, pick them gently, do not press them with your hands, in order to ensure the medicinal quality and performance of the flowers, the flowers picked on the same day should be dried in time, spread evenly and thinly on the mat on a sunny day, and let the sun dry naturally. Heating and drying on cloudy and rainy days, build a square drying room indoors, put a heating device at the bottom, and set up a layered drying rack with a spacing of 25 centimeters between each layer. Spread the flowers evenly on the baking utensils with a thickness of not more than 1 centimeter, and move them into the shelves. The initial drying temperature was 30-35 ℃, then it rose to 40 ℃ after 2 hours, and kept at 45-50 ℃ in 5-10 hours. After about 10 hours, most of the water in the flowers was discharged, and the drying temperature rose to 55 ℃. When the dried flowers are pinched and audible, scratched and broken, pure color, strong aroma can be. The drying process should be carried out continuously, drying and drying, and can not be stopped or turned at will. Because the drying method has many advantages, it can better ensure the medicinal value of flowers, so it is often used. You can also bask gently and then bake until dry.
