Planting method of Shegan of traditional Chinese Medicine

The dried rhizome of traditional Chinese medicine is the dried rhizome of Iridaceae, which belongs to perennial herbs. Like warm and dry climate, cold and drought resistant. Often born on hillsides, grasslands, wilderness, edge of miscellaneous trees. Distributed in all parts of China, mainly produced in Hebei and Hunan provinces. So, how is the traditional Chinese medicine Shegan planted?

Shegan, also known as Cungan, black fan, golden butterfly, belongs to the Iridaceae plant, with the rhizome of medicine, with heat-clearing, detoxification, phlegm, pharynx function. Its rhizome contains subwild iris flavone and other ingredients, which has the effects of anti-inflammation and detoxification, antivirus, diuresis and inhibition of cervical cancer cells.

The seeds begin to germinate when the air temperature is 20 ℃ ~ 25 ℃ and the soil moisture is 50%. When the temperature is 25 ℃ ~ 35 ℃, the light time is long, the soil temperature is high and the rainfall is sufficient, the seeds grow vigorously. The dry shoot is drought-resistant and cold-tolerant, and it can survive the winter naturally in the area with an air temperature of-17 ℃. Shegan is not strict on the soil, sandy land and sloping land can grow, but the plant grows well in the sandy loam with high topography, loose fertility and good drainage, the soil pH is neutral and slightly alkaline, and the rhizome in low-lying waterlogged land is easy to rot.

1. Garden choice. It is appropriate to choose sandy soil, flat land or gentle slope land with high topography, sunny, deep soil layer and good drainage. If the barren mountain sloping land is used for planting, it is appropriate to turn the land in autumn and winter in the first year, so that it has a period of weathering and ripening process, and then plough again in the spring of the following year to remove tree roots, weeds and stones. For those planted with arable land, ploughing once before planting, 100 kg of superphosphate or 50 kg of compound fertilizer per mu.

two。 Because of the time to plant. If seed direct seeding is used, it can be sowed in spring or autumn. Spring sowing from early March to mid-April, autumn sowing from September to October, sowing seeds on the border surface with a row spacing of 30 cm and a depth of 1.5 cm. After sowing, the management should be strengthened to keep the border soil moist, so as to facilitate seed germination and seedling growth. After the seedlings are unearthed, the seedlings should be ploughed and weeded in time. When the seedlings are 6-10 cm high, the seedlings should be pulled open; if bolting occurs, they should be cut off to facilitate root growth. The amount of seeds used for direct seeding is about 5kg / mu. The amount of seeds used for raising seedlings is 5-6 kg per mu. Autumn sowing comes out in spring, and spring sowing in 30 days. After growing for one year, it can be transplanted in autumn or spring, and the seedling can be transplanted to 60.7 mu per mu.

3. Ploughing and weeding. After shoot stem emergence or transplanting, it is necessary to plough and weed frequently, usually 3-4 times a year, spring sowing once in May, July and November in the first year, and March, June and November in the second year.

4. Dressing up at the right time. Shegan is a fertilizer-loving plant. In addition to applying sufficient base fertilizer, it is fertilized once in spring, summer and autumn in the second year. The application of urea 25kg / mu and compound fertilizer 25kg / mu in spring and summer and compound fertilizer per mu in autumn could promote the growth of aboveground stems and leaves, while the latter could promote the growth of rhizome and increase the yield.

5. Drainage and irrigation. Shoot dry for fear of waterlogging, dredge ditches and drain in time after heavy rain to prevent rotting roots. Although Shegan is tolerant to drought, it is necessary to keep the border soil moist at the seedling stage and after transplanting to facilitate the growth of seedlings. In case of drought at seedling stage, it should be properly watered or irrigated. After the seedling height is 10 cm, less or no water can be irrigated.

6. Pick the bud in time. If planted with rhizome, it can blossom in the same year; when transplanting or direct seeding with seeds, it will blossom less in the same year, and it will blossom more in the following year, and its flowering period is long, flowering and fruiting is more, so it consumes a lot of nutrients and affects the growth of rhizome. In addition to keeping the seed land, the buds should be removed after the dew is dry on a sunny morning during bolting, and be removed in stages and in batches. If you harvest the seeds, you can not pick the buds.

7. Harvest and processing. The dry shoot was harvested for 2 to 3 years or for many years, and the vast majority of them were harvested in two years. Harvest in autumn, its rhizome is about 6-8 cm deep, dig out the rhizome at the end of autumn, remove the fibrous root and dry it as medicinal materials. The average yield of dry goods per mu is 250kg to 300kg. At present, the price of dry goods in the market is about 30 yuan per kilogram, and the benefit is 7500-9000 yuan per mu.

The above is about the planting methods of traditional Chinese medicine Shegan. At the beginning of this article, we have mentioned that traditional Chinese medicine Shegan is distributed all over the country, and its regionality is not very strong. Shegan, as a kind of medicinal plant, should be planted? How much do you plant? This also needs to focus on its price trend. To learn more about the Shegan price index, you can inquire about it on the Kangmei traditional Chinese Medicine Network.
