Platycodon grandiflorum planting technology
The Platycodon grandiflorum is a perennial plant. It is rooted after peeling and used as an herb. There are Xuanfei, cold, expectorant cough, swelling and pus discharge function, the main treatment of exogenous cough, sore throat, cough uncomfortable, chest tightness, abdominal distension, bronchitis, etc., is a combination of medicine and food. For many years, the amount of small foods that people are accustomed to use far exceeds the amount of medical use. It is mainly produced in the northeastern provinces and in Shandong, Jiangsu, Anhui, Zhejiang, and other provinces. Due to the sharp decline in wild resources, it is mainly home-based. Due to the development of the food industry and the increase in export volume in recent years, the demand for bellflowers has increased. Growth habit Campanulaceae more like a cool and humid environment, wild in the sunny slopes and grass. Strong cold resistance, sealing Hanli general requirements for the soil is not strict, low moisture, easy to rot, the seed life is generally one year under normal conditions, the seed germination temperature is suitable for 15-30 degrees, hi sunny. Cultivation Techniques Land selection and site preparation: The best sandy soil or humus soil with deep soil and good drainage is the best, followed by loam soil. It is forbidden to choose low-lying water, poor drainage, and annual heavy white soil, and conditions are suitable for plowing. The appropriate amount can be applied to farmyard manure or plant ash, 30 kg of diamine, deep-turn 30 cm, made after leveling. 2 meters wide, 15 centimeters high, the length of the trampoline depends on the terrain. Seed direct seeding: seed selection, high germination rate, and disease-free seed sowing. Sowing is divided into autumn and spring sowing, and autumn sowing is completed before freezing. Spring waves can be sown with a spacing of 20 centimeters when the local temperature is stable above 18 degrees and until the end of June. For uniform seeding, seeds can be mixed before sowing. After 3 times fine sand, evenly spread the seeds into the sowing ditch, cover the soil to a depth of 1 cm, and suppress the watering after sowing, in order to make the seedlings emerge quickly and evenly after sowing, and soak the seeds with water for 10 hours before sowing. After being put into a wet cloth bag, germination is performed at about room temperature of 25 degrees, and rinsed once or twice a day with fresh water, and sowed again when about 5 to 7 days when the seed is exposed. Transplanting: Because the transplanting of bellflowers is not only lower than the live broadcast in terms of output and product quality, but also increased labor input, it is generally not used. Field management Seedlings Dingmiao: When the seedling height 3 cm left with the combination of seedlings to dense and seedlings, when the seedling height 5 cm when the spacing of 7-10 cm from the planting seedlings, such as the lack of seedlings should be timely planting. Watering and draining: Platycodon grandiflorum seedlings are afraid of drought in the early stage, and should be watered in time in case of drought. In the rainy season, attention should be paid to the elimination of accumulated water in the ground and the prevention of internal erosion.
