Radix Ginseng is a kind of plant that can be used in medicine. It is generally dried in the sun and has no poison. It has the functions of clearing away heat and moistening the lungs, nourishing and so on. Sand ginseng often grows in grass or rock crevices, but it is rare to grow at high altitude.

What are the types of sand ginseng?

1. Radix Glehniae

Radix Scutellariae, also known as Laiyang ginseng, sea ginseng, silver ginseng, Liao sand ginseng, Su Tiao ginseng, Radix Ginseng, etc., is the root of Umbelliferae plant, with the effect of nourishing yin and clearing lung, expelling phlegm and relieving cough. It is mainly produced in Shandong, Hebei, Liaoning, Inner Mongolia and other places.

2. Nansha ginseng

Nansha ginseng is the dry root of Campanulaceae, which is produced in Northeast, Inner Mongolia, Hebei, Shanxi, Shandong, East China, Guangdong, Guangxi, Yunnan, Sichuan, Guizhou and other places. Adenophora is produced in Jiangsu, Anhui, Zhejiang, Jiangxi, Hunan and other places, with the effect of nourishing yin and clearing lungs, tonifying stomach and promoting fluid, resolving phlegm and tonifying qi It is commonly used in lung heat and dryness cough, yin deficiency and fatigue cough, dry cough and sputum stickiness, stomach yin deficiency, less food vomiting, qi yin deficiency, irritable heat and dry mouth.

3. Radix Ginseng

This species differs from the former two in that the leaves are 3-6 whorled, ovoid to linear-lanceolate. Inflorescence branches are also often whorled; disk short, 2-4mm long, less than 1mm in diameter; Corolla slender, nearly tubular, mouth slightly constricted, lobes ca. 2mm. The florescence is from July to September.

4. Sand ginseng of apricot leaves

The difference between this species and Radix Ginseng is that the cauline leaves are sessile or only cuneate in the upper part of the stem, the leaf base is often cuneate, and the basal leaves are long stipitate. Inflorescence branches stout, almost spreading or arched upward; Calyx lobes ovate to long ovate, widest in middle and lower parts, usually more or less overlapping, 1.5-4mm wide, disk multifunctional hairy, rarely glabrous; style as long as Corolla. The florescence is from July to September.

5. Radix Ginseng

The difference between this species and the first four is that the stem is often densely anatropous hispidulous; cauline leaves sessile, rarely cuneate short stalked; leaf blade ovate-elliptic, oblong, narrowly elliptic and Obovate, both surfaces hairy, margin with 2 to several thick teeth. Inflorescences usually branched at base; disk hairy; style subequal to Corolla. The flowering period is from July to October and the fruiting period is from October to November.

6. Adenophora yunnanensis

The difference between this species and the first three species is that cauline leaves are evenly distributed on the stem; often sessile, leaf blade ovoid to long-ovate or Obovate, sparsely hispid above, densely hirsute below or only hirsute on leaf veins. False racemes; disk shortly cylindric, not more than 1 mm long; calyx margin with 1-3 pairs of denticulate. The florescence is from August to October.

Second, how to grow sand ginseng?

1. Autumn sowing: with the seeds harvested in the same year, wet the seeds more than 20 days before sowing and soften the kernels. Trench 20 cm apart, 1.5 cm deep, spread the seeds evenly into the ditch, cover the soil strictly, slightly suppress, and water. When sowing in pure sandy land, in order to prevent the movement of sand on the surface, cover a small layer of soil, and break the unbroken soil before emergence in the next spring, so as not to hinder the emergence of seedlings.

two。 Spring sowing: the newly harvested seeds are treated in sand storage in the middle of November, that is, select the back sun, dig a pit 30cm to 40cm deep (length and width depend on the number of seeds), mix 1 part of the wet seed with 3 parts of slightly moist fine sand, put into the pit, cover with straw or straw curtain, cover with a layer of soil. Sow the seeds when they are about to germinate the following year. For example, if you sow dry seeds in spring, you will have to soak for more than 20 days. The sowing rate is 6 kg per 667 square meters.

3. Seed retention: select sandy loam with good drainage to establish seed field, apply sufficient base fertilizer, and add calcium superphosphate. The robust 1-year-old ginseng root was selected as seed. In September, it was planted according to the row spacing of 30 cm × 15 cm. After emergence in the following spring, strengthen field management and apply more nitrogen and phosphorus fertilizer before flowering to make the grain full. The seeds mature when the fruit is yellowish brown in the middle of July.

4. Cultivation and management

Intertillage weeding: after emergence, ploughing and weeding in time to preserve soil moisture, in order to facilitate squatting seedlings. Because Radix Glehniae is a densely planted crop, as the seedlings grow tall, the row spacing is small, the stem is easy to break, it is not suitable to plough with hoe, iron rake can be used to loosen the soil or pull grass.

Seedlings: seedlings 5 cm high time seedlings, plant spacing 3 cm 5 cm. Too thin roots are easy to bifurcate, too dense seedlings grow weakly and are easy to suffer from diseases.

Topdressing: apply light human and animal manure water once when the seedling is 10 cm high. At the beginning of July, phosphorus and potassium fertilizer were mainly applied to promote the growth of roots. Water once after fertilization.
