Cultivation and management of medicinal honeysuckle

Honeysuckle is a perennial evergreen liana, and its whole body has a variety of medicinal value To cultivate medicinal honeysuckle, we should do the following: 1 Medicinal varieties require strong branches, reasonable structure, more flowering times, more flowers, good quality and high yield For example, chicken claw flower and big hairy flower are better varieties for drug cultivation 2 Select the land to build the garden The sandy loam plot with open ground, loose soil layer, convenient drainage and irrigation and rich humus can be selected as the planting garden, and the scattered plots in front of the house, behind the house, beside the ditch, beside the pond can also be used for deep soil reclamation 50 tons of farmyard fertilizer can be applied per mu to form a 1.2m-wide border 3 Cultivate strong seedlings Honeysuckle is mainly propagated by cutting Before sprouting in early spring, 1-4 buds of cuttings are selected to remove the lower leaves They are cut and planted on the prepared seedbed, shaded and watered In the dry season, spray water in the morning and evening respectively In the daytime, water as appropriate according to the soil conditions After rooting and growing leaves of cuttings, gradually remove the sunshade and water 1-2% diluted organic fertilizer every half month With the growth of seedlings, the concentration of fertilizer should be increased, and it can be transplanted into the field half a year later 4 Scientific management Fertilization is carried out before the germination of plants in early spring or the cold wave in early winter A furrow or ring ditch was opened beside the plant, each plant was applied with 10 kg of decomposed organic fertilizer, 0.1 kg of ammonium sulfate and 0.1 kg of superphosphate From May to June, two or three times of application of lean organic fertilizer and water accelerated the growth of seedlings In order to increase the number of flower picking stubbles and improve the quality and yield of flowers, 0.5-1% potassium dihydrogen phosphate can be sprayed on the leaves of adult plants at the flower bud differentiation stage of each stubble The ideal plant form of medicinal honeysuckle is a small umbrella like shrub with many branches This must be done by trimming The specific method is to cut off the upper half at the height of 30cm of the trunk, promote the germination and branching of buds under the cutting mouth, keep 4-5 branches with uniform distribution and the same thickness, and then cut off the upper half of branches at all levels Before sprouting in spring every year, it is necessary to carry out comprehensive garden clearing, cut off the old branches, decayed branches, thin and weak branches, shade branches, root tillers and seedlings, and destroy them in a centralized way to reduce the source of disease and the population base The main pests of honeysuckle are aphids and coffee tiger longicorn The former is harmful to leaves and flower buds, so it should be controlled in time In the latter, larvae eat the xylem of rattan trunk, causing the trunk cavity The control method is to carry out artificial hook killing in larval stage, or block the hole with cotton wads soaked with dichlorvos solution, and then seal it with mud The main disease is honeysuckle brown spot, which is usually serious in summer, causing leaf brown spot necrosis In the early stage of the disease, we used Jinggangmycin spray 5 Harvesting and processing The medicinal parts of honeysuckle are mainly flowers When harvesting, we should not only see the flowers but also observe the sky, so that we can harvest them at the right time When the flower base is greenish green, the top is milky white, in bud, bright color, and full of brightness, it is the best sign for picking flowers Pick flowers when the dew is not dry in sunny days, light picking and light putting, do not use hand pressure In order to ensure the medicinal quality of flowers, the flowers picked on that day should be dried in time, evenly and thinly spread on the sun mat in sunny days, and let the sun dry naturally In rainy days, it will be heated and dried A square drying room will be built in the room with heating device at the bottom The room will be equipped with layered drying frame The space between each layer is 25cm The flowers will be evenly spread on the drying apparatus The spreading thickness will not be more than 1cm and will be moved onto the layer frame The initial drying temperature is 30-35 ℃, rise to 40 ℃ after 2 hours, keep at 45-50 ℃ after 5-10 hours, and most of the water in the flowers is discharged after about 10 hours, and the drying temperature rises to 55 ℃ When the dried flower is kneaded and has sound, scratched and broken, the color is pure, and the fragrance is rich The drying process should be carried out continuously, one drying and drying, and the drying can not be stopped or flipped at will in the middle of the drying process Because the drying method has many advantages, it can more ensure the medicinal value of flowers, so it is more used You can also light sun first and then bake until it is dry.
