What is the price of Erigeron breviscapus seeds? Detailed planting method

Erigeron breviscapus, also known as Di Ding Cao, Di Chao Yang, Shuang Kui Hua, etc., is a perennial herb of the genus Erigeron in the Asteraceae family, distributed in the southwest region of China, especially abundant in Yunnan. The whole plant is used as medicine and has the effects of mildly cold detoxification, dispelling wind and removing dampness, promoting blood circulation and removing blood stasis, dredging meridians and activating collaterals, and reducing inflammation and relieving pain. Let us take a look at the price of Erigeron breviscapus seeds and the planting method below!

How much is one jin of Erigeron breviscapus seeds?

The price of Erigeron breviscapus seeds is about 400 to 600 yuan per jin, but prices vary greatly depending on seed quality, variety and purchase quantity. Erigeron breviscapus has wide adaptability to the environment and strong stress resistance, with no special requirements for environmental conditions and cultivation. It can be planted in areas at an altitude of 1100 to 1900 m, and is especially suitable for development in dry and hot low-hot valley areas at an altitude of 1300 to 1600 m. Areas with an annual average temperature of 16 to 20°C, an average annual relative humidity of about 60%, and annual rainfall of 600 to 1200 mm are most suitable. It has relatively high requirements for sunlight conditions, and the longer the sunshine hours, the better. It prefers nitrogen in the early growth stage and phosphorus in the later stage.

Sowing method of Erigeron breviscapus

1. Seed propagation: Erigeron breviscapus must use newly produced seeds of the current year. New seeds germinate quickly and have a high germination rate, and the seedlings grow uniformly and robustly, which is convenient for management. The germination rate of old seeds stored for a year is extremely low.

2. Sowing method: Erigeron breviscapus seeds can be broadcast, drilled or dibbled, but drilling is preferable. For drilling, the sowing width is 5 to 10 cm, the depth is 1 to 2 cm, and the row spacing is 10 cm.

3. Seed treatment: Soak Erigeron breviscapus seeds in warm water at about 30°C for 4 to 5 hours, then remove the seeds and leave them for about 3 hours until the surface moisture is slightly dry. Then evenly scatter the seeds into the furrows, cover with about 1 cm of soil, cover the surface with grass, and water thoroughly.

4. Sowing time: Spring sowing of Erigeron breviscapus may result in uneven emergence due to drought, while summer and autumn sowing produce uniform emergence. Spring sowing is done from late February to early March, summer sowing is carried out during the rainy season in May to June, and autumn sowing is carried out in August to September. Seeds germinate 10 to 20 days after sowing.

5. Post-sowing management: Erigeron breviscapus seed germination requires more water, and seedlings are averse to strong light and high temperatures. Production should adopt methods such as covering to preserve moisture and shading to ensure sufficient water and a suitable ecological environment for seed germination and seedling growth.

Seedling stage management of Erigeron breviscapus

1. Timely shading: Erigeron breviscapus seedlings grow thin and weak, and are afraid of drought, waterlogging and sun exposure. Proper shading of the seedling bed is an important measure in seedling stage management. After the seedlings survive, their tolerance to strong light increases, and they can resist direct sunlight and grow in the open field.

2. Watering and drainage: During the seedling stage, Erigeron breviscapus should be watered appropriately, and flooding irrigation should not be used. During the emergence and seedling stages, the bed surface should be kept moist to facilitate emergence and seedling growth. After the seedlings grow larger, watering can be reduced, and attention should be paid to drainage during the rainy season.

3. Weeding and fertilizing: The Erigeron breviscapus seedling bed should be frequently weeded to prevent weed overgrowth. Loosening the soil should be shallow to avoid damaging the roots. Weeding should be carried out on cloudy days or in the morning or evening. Combined with irrigation, 2 to 3 applications of clear manure water can be applied to promote seedling growth.

Planting method of Erigeron breviscapus

1. Land selection and preparation: For Erigeron breviscapus, it is advisable to choose a sunny, flat place with good drainage and irrigation conditions and convenient transportation as the planting site. The soil should be loose, fertile sandy loam rich in humus. After selecting the land, stones, dead branches and other debris should be removed in time.

2. Applying sufficient base fertilizer: When preparing the land for Erigeron breviscapus, plow about 20 cm deep, apply 3000 to 3500 kg of decomposed barnyard manure or farmyard manure per mu as base fertilizer, cultivate carefully, and then level and make beds.

3. Intertillage and weeding: Before the rows close, Erigeron breviscapus should be frequently weeded and the soil loosened, and care should be taken to earth up so that the rhizome is not exposed above the ground. Loosening the soil should be shallow to prevent root damage. After the rows close, no more soil loosening is needed.

4. Drainage and irrigation: After transplanting, Erigeron breviscapus should keep the bed surface moist often, and care should be taken to keep the surface loose and the lower layer moist. However, during the rainy season, attention should be paid to drainage to prevent root rot.

5. Reasonable topdressing: After Erigeron breviscapus survives transplanting, apply human manure and urine once, 800 to 1000 kg per mu, and then earth up. In winter, apply about 1500 kg of barnyard manure per mu to promote safe overwintering and vigorous growth the following year.

6. Timely flower thinning: The flowering period of Erigeron breviscapus is relatively long, so it consumes more nutrients. If it is not a seed production field, flowers should be thinned in time to prevent nutrient consumption, facilitate plant growth and increase yield.

7. Harvest and processing: Erigeron breviscapus is harvested 1 to 2 years after transplanting or multiple times within one year. After the plants are dug back or harvested, remove the soil, tie them into small bundles, and dry them in a cool, ventilated and dry place in the shade, or properly sun-dry or oven-dry them. Washing with water and exposure to the sun are prohibited.
