Codonopsis, taking root medicine. Sexual sweetness, there is nourishing Qi, thirst and other effects. For the traditional Chinese medicine. Because its performance is very similar to ginseng, it can also be eaten in soup. Its sales volume and export volume have been increasing year by year and have been prolonged. Codonopsis ginseng has a growth cycle of two years. It produces 300-350 kilograms of dry codonopsis and has a high yield of 500 kilograms.
Growth habits: Warm and cool climate, cold-resistant, roots can be exposed to winter in the soil. Seedlings are wet, shaded and afraid of glare. The lack of water after sowing is not easy to emerge, and water shortage after emergence can cause a large number of deaths. High temperature can easily cause rot. Big seedlings and plants are full of sunshine. It is suitable for cultivation in sandy loam where the soil is deep, well drained, and loose in soil and rich in humus. Mu species 2 pounds.
Cultivation techniques: Seedlings are transplanted and seeded directly, but the former are good. 1 Seed Treatment Seeds are soaked in warm water of 40-45°C before sowing, stirring, mixing, and putting seeds until the water temperature is not reduced to hot. Soak for another 5 minutes. Then, the seed is placed in a gauze bag, washed several times, placed on a sand pile, and then lysed once every 3-4 hours with warm water at 15° C. After 5-6 days, the seed can be sown when it is cracked. The seeds in the cloth bag can also be placed in water at 40°C for a predetermined time to keep it moist, and when the seeds are germinated in 4-5 days, they can be sown. 2 The live broadcast method sows the seed between the frost and the winter, and the seed does not need to be processed. Insulation and prevention of sun exposure, when the seedlings pay a high salary of -10 cm, the cover is gradually removed, and timely weeding and soil watering are performed to keep the soil moist. 3, planting, seedlings grow a year later, the spring or autumn colonization, spring in March and late to early April, autumn in October, late to early November, the seedlings will be picked up during transplanting, remove the damage, Diseased and weak seedlings, with 16-30 cm depth and 20-30 cm spacing, 7-10 meters away from the plant spacing. Put the roots obliquely in the ditch so that the roots are lifted and the roots are slightly straightened. The soil is better than 7 cm from the top of the reed.
Field management: 1. Cultivated weeding: Weeding after weeding begins, weed removal is one of the main measures to ensure production. 2 Top dressing: after planting and survival, the seedling height is about 15 cm. It can be applied to manure urine 1000-1500 kg per mu. Afterwards, stems, leaves and vines are not suitable for top dressing. 3. Drainage and irrigation: water should be poured after planting, and less water should be added after seedling survival. Or no irrigation, timely drainage in the rainy season to prevent rot. 4. Stretching: The height of the seedlings planted on the ground is 30 centimeters. A scaffold is set up to facilitate the growth of the seedlings, which can increase the resistance to disease and reduce the disease. Advantageous root growth and solid pest control: Diseases: 1. Rust: It began in mid-May and early June, and June-July was the epidemic period. Leaves, stems and flowers can be killed. Prevention and control methods, the incidence of spraying 50% dinitranic dispersion 200 times or 200 times the enemy rust sodium, 7-10 days 1, continuous 2-3 times. 2. Root rot: Usually when the soil is too wet and the temperature is too high. The disease is more prone to occur. In the early stages of disease, the fibrous roots near the ground turn dark brown, and when the rot is severe, the whole root is brownish and watery, and the aboveground part is dead. Prevention and control methods (1) and crop rotation; (2) drainage in the rainy season (3) When the soil preparation, use 50% carbendazim 500 times per acre to water the ward. Insect pests 1, underground pests: from April to May, there are mainly ground tigers, which damage the tender stems and roots. Control methods: Use 800 times liquid of trichlorfon and 1000 times liquid of 1650 emulsion to seduce the roots. 2, Yeah: can be used for 40% Dimethoprim 2000 times spray. Red spider: The main disease seedlings and planted leaves can be sprayed with 50% pupa pine 1000--2000 times.
Harvesting and processing: Transplanting Codonopsis pilosula harvested in autumn that year, dig out the roots, wash, dry and dry by 2% to 3% dry, then soften and dry the medicine. (Hubei Dangyang Agricultural 110 Service Center)
