What Is Centipeda minima? A Detailed Guide to Its Cultivation Techniques

Centipeda minima is a common wild plant in China, often found along roadsides and around houses where humidity is relatively high. Because it has detoxifying, cough-relieving and itch-relieving effects, it is widely used as a medicinal herb. So what is Centipeda minima? What are its cultivation techniques?

1. What is Centipeda minima?

1. Centipeda minima is an annual small herbaceous plant of the order Asterales, family Asteraceae, genus Centipeda. The plant height is about 4 cm, and the whole plant is twisted into clumps. The long roots are very thin and pale yellow, and the long stems are also very thin, bearing many branches, and each branch bears many wedge-shaped oblanceolate leaves with pointed tips and irregularly serrated edges. The flowers are pale yellow or yellow-green, tubular, with multiple layers of female flowers and inconspicuous lobes at the edges, and the fruit is elliptical. It generally flowers from May to October.

2. Centipeda minima has high medicinal value and contains abundant flavonoid glycosides, amino acids, organic acids and other substances. It has effects of resolving phlegm and relieving cough, detoxifying, dispelling wind-cold and anti-allergy, and can effectively treat diseases such as colds, malaria and pertussis. However, because it is warm in nature, people with a heat-disease constitution or pregnant women should not consume it.

2. What cultivation techniques are there for Centipeda minima?

1. Site selection and land preparation: sandy loam soil is best for planting

Centipeda minima is suitable for growing in environments with loose, fertile soil and good drainage, so when selecting a site, choose sandy loam soil for planting as much as possible. After selecting the site, deep-plow the soil and apply 3500 kg of decomposed farmyard manure per mu, then level it for later planting.

2. Sowing and seedling raising: sowing in March to May or in August is fine

(1) Seed treatment: Centipeda minima seeds are very small. Generally, after collection, they should first be sun-dried, the outer fruit skin rubbed off, and then the seeds taken out. The selected seeds are best soaked in water for a while to remove the outer waxy layer, and then evenly mixed with fine soil or fine sand.

(2) Sowing time: sowing in March to May or in August is fine. Generally, those sown from March to May are mostly for commercial use, while those sown in August are mostly for commercial use or for seed retention.

(3) Sowing method: Centipeda minima can be sown by broadcasting or drilling. For broadcasting, directly scatter the seeds evenly on the seedbed, then cover with a thin layer of soil and water lightly. For drilling, dig shallow furrows at a row spacing of 30 cm, then evenly scatter the seeds in the furrows and finally cover with soil. The two methods of drilling and broadcasting are about the same, except that broadcasting uses more seeds.

3. Field management techniques: do a good job in water and fertilizer management and thinning and replanting seedlings

(1) Water requirements: Centipeda minima does not have high water requirements; just keep the soil moist, so in summer it can be watered more, and in rainy seasons drainage measures should be taken.

(2) Reasonable thinning and replanting: after Centipeda minima has grown for a certain stage, check the field conditions in time, promptly remove weak and dead seedlings, and transplant dense seedlings in time to ensure uniform seedlings.

(3) Fertilizer requirements: Centipeda minima has a short growth period. During the growing period, apply more farmyard manure, and stop fertilizing until before flowering.

The above is a detailed introduction to what Centipeda minima is and its cultivation techniques. I hope it is helpful to everyone.
