Detailed Introduction to Polygonatum Price and Planting Methods
Polygonatum is a traditional tonic medicinal herb, also known as Tiger Ginger, Chicken-head Ginseng, Yellow Chicken Vegetable, etc. It is the dried rhizome of the Liliaceae plants Polygonatum kingianum, Polygonatum sibiricum, or Polygonatum cyrtonema. According to different shapes, it is commonly called Large Polygonatum, Chicken-head Polygonatum, Ginger-shaped Polygonatum, etc. When used as medicine, it has the effects of tonifying qi and promoting fluid production, strengthening the spleen and moistening the lungs, and nourishing yin and benefiting the kidneys. Now let us take a look at Polygonatum price and planting methods!
How much does Polygonatum cost per jin?
The price of Polygonatum is about 15-20 yuan per jin, but prices vary greatly depending on variety, quality, place of origin, and market. For example, ordinary Chicken-head Polygonatum is about 13-15 yuan per jin, premium ordinary Polygonatum is about 18-20 yuan per jin, and the price of premium Polygonatum slices is above 40 yuan. At the same time, the size of Polygonatum directly affects its color and price. Smaller Polygonatum is relatively cheaper, but its medicinal components are generally about the same.
Propagation Methods of Polygonatum
1. Rhizome propagation: For rhizome propagation of Polygonatum, dig up the underground rhizome in late autumn or early spring, select the tender part at the tip and cut it into several sections, with each section having 3 or 4 nodes. After the wounds are slightly dried, plant them in a prepared bed, cover with soil, press lightly, and water. Keep the soil moist before emergence.
2. Seed propagation: After Polygonatum seeds mature in August, immediately carry out sand storage treatment. In late March of the second year, screen out the seeds and evenly sow them in shallow furrows on the bed surface. After covering with soil, water and cover with a layer of grass. Remove the covering grass before emergence. Thin seedlings appropriately where they are too dense, and transplant after 1 year.
Planting Methods of Polygonatum
1. Land selection and preparation: For Polygonatum planting, choose moist land with sufficient shade. The soil should preferably be loam or sandy loam with loose texture and good water retention. During land preparation, apply 2000 kg of farmyard manure per mu and plow it into the soil as base fertilizer, then rake finely, level, and make beds.
2. Seedling raising and transplanting: Polygonatum transplanting in northern regions is mostly carried out in early April. On the prepared planting plot, dig holes at a row spacing of 30 cm and a plant spacing of 15 cm, then plant the grown seedlings into the holes, 2 plants per hole, cover with soil and press firmly, and water thoroughly once.
3. Intertillage and weeding: During the growth period of Polygonatum plants, intertillage and weeding should be carried out frequently, once each in April, June, September, and November every year. Shallow hoeing is advisable to avoid damaging the roots, and appropriate hilling should be done to promote strong plants. Later, pulling weeds is sufficient.
4. Reasonable topdressing: Polygonatum is topdressed each year in combination with intertillage. Each time, apply 1000-1500 kg/mu of high-quality human and livestock manure. Before winter, apply 1200-1500 kg/mu of high-quality farmyard manure again, mixed with 50 kg of superphosphate and 50 kg of cake fertilizer.
5. Timely drainage and irrigation: Polygonatum likes moisture and fears drought. The field should often remain moist. In dry weather, water in time, but in the rainy season, prevent water accumulation and drain promptly to avoid root rot.
6. Removing flowers: Polygonatum flowers and fruits consume a large amount of nutrients and affect rhizome growth. Therefore, flower buds should be removed in time before flower bud formation to promote the concentrated transfer of nutrients to the harvested rhizome part and increase yield.
7. Disease and pest control: For Polygonatum leaf spot disease, use 65% zineb wettable powder at 500 times dilution. For black spot disease, spray 1:1:100 Bordeaux mixture. For white grubs, use 75% phoxim emulsifiable concentrate to dress seeds at 0.1% of seed weight, or during occurrence, drench with 90% trichlorfon at 1000 times dilution.
8. Harvesting and processing: Polygonatum propagated by rhizome is dug and harvested 2-3 years after planting, and that propagated by seed is dug and harvested 3-4 years after planting. Harvesting can be done in both spring and autumn, but the quality is better when harvested in autumn. The yield is 400-500 kg per mu, and high yield can reach 600 kg.
