It is called "Doraaji" in the Korean language, said to be the name of a girl. There is a very famous folk song about Platycodon grandiflorus in Korean songs called "Doraaji Song":"Doraaji, white Platycodon grandiflorus flowers fill the mountains and fields, just by digging up a couple of plants, you can fill my small vegetable basket. Hey hey yo, you, hey yo..."Picking, basket after basket, the song describes the scene of picking Platycodon grandiflorus.In the children's cartoon "Inuyasha," the characters and story come from the legend of Platycodon grandiflorus, which is also a flower loved by girls because it symbolizes loyalty, representing love that never changes. Its legend is very beautiful, symbolizing eternal love, and it is one of the flowers to express one's feelings to one's lover during the dating period. The meaning of the language of flowers for Platycodon grandiflorus has two interpretations: one is eternal love, and the other is hopeless love: representing the enduring love even though the love is hopeless. When Platycodon grandiflorus flowers bloom, some can grasp it, and some cannot; even if they can't grasp it, they will keep this hopeless love.Platycodon grandiflorus is a commonly used Chinese medicinal herb with a long history, sold domestically and internationally. It has the effects of clearing the lungs, resolving phlegm, benefiting the throat, and expelling pus. Originally wild, it was successfully trial-cultivated in the 1970s and is now widely planted in Anhui, Henan, Hubei, Hebei, Shandong, Sichuan, Zhejiang, and other regions in the Northeast and Inner Mongolia, becoming an increasingly popular Chinese medicinal herb.How to plant Platycodon grandiflorus well? Guangxi Zhongnong Fuyu International Agricultural Technology Co., Ltd. has summed up a set of planting and cultivation management techniques for Platycodon grandiflorus after years of planting experience, bringing a gospel to poor farmers for getting rich and lifting themselves out of poverty.Growing EnvironmentPlatycodon grandiflorus originally grows in dry slopes, hilly slopes, forest edges, shrubbery, and dry grasslands and meadows. It is cultivated in sunny, wind-protected, and fertile areas. It prefers light, warm climate, can endure cold, and is afraid of waterlogging. It grows well in deep, fertile soil rich in humus, and easily rots in soil with excessive moisture or waterlogging.Planting Techniques1. Land preparationChoose a sunny, wind-protected, fertile, deep, loose, well-drained, and humus-rich soil for planting. Plow 25 to 40 centimeters deep in winter, apply enough base fertilizer during plowing, apply 2500 kilograms of organic fertilizer and 25 kilograms of superphosphate per 667 square meters. Then, before sowing in the following spring, plow and rake the soil again to form flat or raised beds about 150 centimeters wide and 30 centimeters wide and 15 centimeters deep. Some areas use ridge planting.2. Breeding methods(1) Sexual propagation: Use direct seeding and transplanting. Direct seeding results in straight and thick main roots with fewer branches, which is convenient for processing. Transplanting seedlings, although beneficial for centralized management, saves labor and land, but the main roots are not distinct, with many branches, making peeling difficult.① Direct seeding: Spring sowing is from late March to mid-April (early April to late May in the Northeast). Before sowing, place the seeds in 50℃ warm water, stir until the water cools, then soak for 8 hours and remove. Cover with a wet burlap bag and germinate. Rinse with warm water twice a day, morning and evening, after 4 to 5 days when the seeds start to germinate, they can be sown. Autumn sowing is from mid-October to early November. Sow in furrows 20 to 25 centimeters apart on the bed surface, evenly sprinkle the seeds in the furrows, cover with 0.6 to 1 centimeter of soil, slightly press, and water, keeping the bed surface moist. After autumn sowing, lightly sprinkle a layer of calcined clay to cover the seeds and then cover with straw to prevent the seeds from being washed away by rain and to keep them warm and moist. Seedlings usually emerge in the following April.② Transplanting: On the prepared beds, make furrows 10 to 15 centimeters apart, sow the seeds, cover with a thin layer of fine soil, press lightly, and cover with straw. After the seedlings emerge, remove the covering straw. Transplant after the aerial parts wither in the autumn or before the seedlings emerge in the following spring. Dig up the roots, make furrows 20 to 25 centimeters apart, with a plant spacing of 6 centimeters, plant along the furrows, cover with fine soil, and slightly press. Water in dry weather.(2) Asexual propagation (root head propagation): Planting period is from late March to early April (postpone appropriately in the Northeast). Cut the root head (rhizome or rhizome) of the harvested Platycodon grandiflorus, 4 to 5 centimeters long, make holes 20 to 25 centimeters apart, 8 to 9 centimeters deep, and plant one in each hole. Cover with soil and water after planting.Cultivation Management1. Thinning and weeding: When the seedlings are 3 to 6 centimeters tall, thin the seedlings 1 to 2 times, thinning the dense seedlings. When the seedlings are 6 centimeters tall, thin the seedlings to a distance of 6 to 10 centimeters. Remove small, weak, and diseased seedlings during thinning. It is necessary to weed and loosen the soil frequently during the seedling stage. Weeding should be gentle to avoid pulling out small seedlings. Thinning should be combined with loosening the soil and weeding. After thinning, cultivate the soil and weed at the right time to keep the soil loose and free of weeds. Loosen the soil shallowly to avoid damaging the roots. After watering, cultivate the soil shallowly when it is dry and wet. When the seedlings are about 15 centimeters tall, apply 20 kilograms of superphosphate and 12 kilograms of ammonium sulfate per 667 square meters, apply in furrows between rows, cultivate the soil after application, and water in dry weather. Apply thin dung once more during the flowering period from June to July. Before the rainy season, cultivate the soil to prevent lodging. If it is dry after thinning, water appropriately. Remove accumulated water in the rainy season to prevent root rot.2. thin flowers and fruit, prevent lodging: Flowering and fruiting consume a lot of nutrients, affecting root growth. Thinning flowers and fruit is an important measure to increase yield. Artificial deflowering has been used in production. Due to the strong apical dominance of Platycodon grandiflorus, after deflowering, side branches quickly sprout, forming new flower buds. This process needs to be repeated every half month, with 5 to 6 deflowerings during the flowering period, which is labor-intensive and inconvenient, and can damage the branches and leaves. The plant hormone Ethephon can be used at a concentration of 750 to 1000 mg/L, sprayed on the flower buds during full bloom, with the flowers fully covered with the solution, applying 75 to 100 kilograms of the solution per 667 square meters, which can achieve the effect of deflowering. This method is efficient, low-cost, and safe, and is worth promoting. Two-year-old Platycodon grandiflorus plants can reach a height of 60 to 90 centimeters and are prone to lodging before flowering. After winter, combine fertilization with earthing up. In the following spring, do not apply too much nitrogen fertilizer to control stem growth. Spraying 500 times liquid dwarfing agent in April and May can thicken the stems and reduce lodging.3. Seed saving: Platycodon grandiflorus has a long flowering period, with the upper part bolting and flowering first, and the fruits maturing from the upper part. In the northern regions, the seeds of the late-stage fruits are often unable to mature due to the climate. In early September, cut off the small side branches and the upper part of the inflorescence to promote fruit maturity and seed filling. From September to October, when the fruits turn from green to yellow, cut off the fruit stems and place them in a ventilated and dry room to after-ripen for 2 to 3 days, then dry and de-husk.Disease and Pest Control(1) Diseases① damping-off: Mainly occurs when the seedlings are unfolding and dying. Control methods: Before sowing, apply 75% pentachloronitrobenzene at 1 kilogram per 667 square meters for soil disinfection. In the early stage of the disease, apply pentachloronitrobenzene 200 times liquid to the diseased area, to a depth of about 5 centimeters.② Ring spot: Mainly affects the leaves. Control methods: Remove withered branches, diseased leaves, and weeds from the field in early winter and burn them. In summer, high temperature and humidity are the seasons for the disease to occur. Maintain good drainage around and between the beds to reduce humidity. Spray 1:1:100 Bordeaux mixture or 50% carbendazim, thiabendazole, or methytobuzim 1000 times liquid in the early stage of the disease.③ Leaf spot disease: A fungal leaf disease. When the disease is severe, the lesions merge, and the leaves wither. Control methods: Same as "ring spot."④ Purple root rot: Affects the roots. Control methods: Practice crop rotation, remove diseased plants early, and burn them;消毒 the affected area with 10% lime water to control the spread; apply more organic fertilizer to improve the soil and enhance plant resistance; apply 50 to 100 kilograms of lime powder per 667 square meters in mountainous areas to also reduce damage.⑤ Root rot: A root disease caused by fungi. When the disease is severe, the entire plant dies. Control methods: Choose soil with deep, loose, and well-drained slopes for planting, combine plowing and fertilization, apply lime nitrogen at 50 to 75 kilograms per 667 square meters for disinfection, and make ridges after half a month. During the seedling stage, combine the control of underground pests with the application of 40% dimethoate emulsion 2000 times liquid, once every 15 days, for 3 to 4 consecutive times.⑥ Anthracnose: Mainly affects the base of the stem. This disease spreads rapidly, often causing the plant to collapse and die. Control methods: Before emergence, spray 70% thiabendazole 500 times liquid; during the onset of the disease, spray 1:1:100 Bordeaux mixture, once every 10 to 15 days, for 3 to 4 consecutive times.⑦ Downy mildew: Mainly affects the leaves, and the roots can also be affected. Control methods: Strengthen field management, drain water in the rainy season; spray 1:1:120 Bordeaux mixture or 500 times liquid of validamycin at the beginning of the disease, once every 2 to 10 days, for 3 to 4 consecutive times.(2) PestsSpider mites, damage the leaves, most likely to occur in dry seasons, can be controlled with dimethoate. Cutworms, bite the tender stems and leaves, can be controlled by manual capture or bait诱杀. Aphids, usually gather on the back of the leaves or stems, absorb sap, causing the leaves to thicken, curl, and the plant to dwarf and grow poorly. Control with dimethoate 2000 times liquid, spray once every 7 to 10 days, for 2 to 3 consecutive times.Harvesting and ProcessingPlatycodon grandiflorus is harvested after 2 or 3 years of planting. It is best to harvest in autumn when the above-ground stems and leaves wither. Harvesting too early results in underdeveloped roots, low drying rate, and poor quality; harvesting too late makes peeling difficult. Harvest by using a hoe to dig up the roots, remove the stems and leaves, and wash and dry the fresh roots. The bark should be scraped off while fresh, as it becomes difficult to peel after some time; after scraping, dry promptly to prevent mold and yellow rust, which affect quality.This article shares the specific content of whether Platycodon grandiflorus roots can be planted and the planting method explanation for everyone to refer to and operate.
