Seed price and planting method of Erigeron breviscapus

Erigeron marigold, Chaoyang, double sunflower, etc., are perennial herbs of the Compositae family, distributed in southwest China, especially in Yunnan. The whole grass has the effects of slight cold and detoxification, expelling wind and dehumidification, promoting blood circulation and removing blood stasis, promoting menstruation, activating collaterals, and relieving inflammation and pain. let's take a look at the seed price and planting method of Erigeron breviscapus.

How much is the seed of Erigeron breviscapus per jin?

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

Sowing method of Erigeron breviscapus

1. Seed propagation: Erigeron breviscapus must use new seeds produced in the same year, the new seeds germinate quickly, the germination rate is high, the seedlings are uniform and robust, which is beneficial to management, and the germination rate of aged seeds is very low every other year.

2. Sowing method: Erigeron breviscapus seed sowing, strip sowing and hole sowing are all possible, but strip sowing is suitable. The width of the strip broadcast is 5 cm 10 cm, the depth 1 cm 2 cm, and the line spacing 10 cm.

3. Seed treatment: the seeds of Erigeron breviscapus were soaked in warm water of about 30 ℃ for 4 hours for 5 hours, then the seeds were removed and placed for about 3 hours until the surface moisture was slightly dry, then the seeds were evenly scattered into the ditch, covered with soil of about 1 cm, covered with grass and watered thoroughly.

4. Sowing time: spring sowing of Erigeron breviscapus may lead to irregular seedling emergence due to drought, summer sowing and autumn sowing neatly, spring sowing from late February to early March, summer sowing in May-June rainy season, autumn sowing in August-September, 10-20 days after seed sowing.

5. Post-sowing management: Erigeron breviscapus seed germination needs more water, and seedlings avoid strong light and high temperature. Mulch should be used to preserve soil moisture and shade in production to ensure sufficient water and suitable ecological environment for seed germination and seedling growth.

Seedling management of Erigeron breviscapus

1. Timely shading: the seedlings of Erigeron breviscapus grow weakly, are afraid of drought, waterlogging and sunburn. Proper shading of the seedling site is an important measure for seedling management. After survival, the seedlings can enhance their tolerance to strong light, resist direct sunlight and grow in the open field.

2. Watering and drainage: Erigeron breviscapus should be properly watered at the fine seedling stage, not flooded, the border surface should be kept moist at the seedling emergence stage and seedling stage to facilitate seedling emergence and seedling growth, the seedlings can be irrigated less after growing up, and drainage should be paid attention to in the rainy season.

3. Weeding and fertilization: the breeding ground of Erigeron breviscapus should remove weeds frequently, prevent grass famine, loosen the soil shallowly, and avoid root injury. Pulling weeds should be carried out in cloudy days or in the morning or evening. Combined with irrigation, clear dung water can be applied for 2 or 3 times to promote seedling growth.

Planting method of Erigeron breviscapus

1. Land selection and preparation: Erigeron breviscapus should be planted in places with sunny, flat terrain, good drainage and irrigation conditions and convenient transportation, and the soil requires loose, fertile and humus-rich sandy loam. After selecting the land, debris such as stones and dead branches should be removed in time.

2. Apply sufficient basic fertilizer: Erigeron breviscapus turns about 20 cm deep during soil preparation, applying rotten stable fertilizer or soil manure 3000kg to 3500kg per mu as base fertilizer, intensive cultivation, and then leveling the border.

3. Ploughing and weeding: Erigeron breviscapus should remove weeds and loosen the soil frequently before sealing, and pay attention to the cultivation of soil roots not exposed to the ground. Loosening the soil should be shallow, so as to prevent the root from being hurt, and the soil will not be loosened after sealing.

4. Drainage and irrigation: always keep the border surface moist after breviscapus transplantation, pay attention to keeping the surface loose and moist below, but pay attention to drainage during the rainy season in order to put it on rotten roots.

5. Reasonable topdressing: after transplanting, Erigeron breviscapus was fertilized with human feces and urine once, 800-1000 kg per mu, and then cultivated. About 1500 kg of barnyard manure is applied per mu in winter to promote safe overwintering and exuberant growth in the following year.

6. timely flower thinning: the flowering period of Erigeron breviscapus is longer, so it consumes more nutrients, if it is not kept in the field, it is necessary to timely flower thinning to prevent nutrient consumption, in order to facilitate plant growth and increase yield.

7. Harvest and processing: Erigeron breviscapus is harvested 1 ~ 2 years after transplanting or harvested many times in one year. After the plant is dug up or harvested, the soil is cleaned and tied into small handfuls, dried or dried properly in a cool, ventilated and dry place, and water washing and sun exposure are avoided.
