Description

A multi-tube type pinellia seed stem planting device

technical field

The invention relates to the technical field of planting of Chinese medicinal materials, in particular to a multi-tube type Pinellia seed stem planting device.

Background technique

Pinellia ternata is a perennial perennial herb of Araceae. The plant is generally 15cm-30cm high, mostly single leaves. The base of the petiole can grow buds with reproductive ability. The diameter of the underground tuber is generally 1cm-2cm, which is approximately spherical. . Pinellia tubers can be used as medicine and contain a variety of chemical components, among which β-sitosterol-glucoside, alkaloids (levoephedrine, etc.), Pinellia protein and inosine are high in content, and contain a small amount of volatile oil, bird glycosides and flavonoids, etc. Various secondary metabolites of Pinellia have anti-tumor, anti-early pregnancy, lowering blood pressure and other effects. In summer and autumn, when the stems and leaves are lush, excavate, remove the outer skin and fibrous roots, and dry or dry it, that is, raw Pinellia. Because of its high toxicity, it is often used after processing. According to different processing methods, it is divided into Pinellia, Ginger Pinellia, Qing Pinellia, etc. Its taste is pungent, warm in nature, and toxic; it belongs to the spleen, stomach, and lung meridians. Functions: Dry dampness and dispel phlegm, harmonize the stomach, reduce inversion and stop vomiting, dispel phlegm and disperse knots, and externally can reduce swelling and relieve pain.

At present, the output of Pinellia comes from wild and artificial cultivation. With the rapid development of Chinese pharmaceutical industry, the national annual demand for Pinellia is about 4.5 million kilograms, and the export volume is about 1.2 million to 2 million kilograms. The current contradiction between supply and demand is increasing. Large, wild Pinellia resources obviously cannot meet the market demand, in order to increase the output of Pinellia, it is necessary to artificially plant Pinellia on a large scale.
