How much is Polygonatum (Huangjing) per jin on the market? Grow it this way for easy high yields

Polygonatum is a common Chinese medicinal herb with effects such as tonifying the spleen and moistening the lungs, so it is widely used as a medicinal material, and many areas are now cultivating it artificially. So how much is Polygonatum per jin on the market? How to grow it for high yields?

1. Introduction to Polygonatum:

1. What are the production areas of Polygonatum?

There are many production areas for Polygonatum. In China, it is cultivated in Zhejiang, Anhui, Guizhou, Yunnan, Sichuan, Guangxi and other places. Among them, Polygonatum cyrtonema is mainly produced in Shaanxi, the coastal areas of Northeast China and Gansu and other places, while Polygonatum kingianum is mainly produced in Yunnan, Guizhou, Sichuan, Guangxi and other places.

2. What types of Polygonatum are there?

Polygonatum kingianum, Polygonatum cyrtonema, Polygonatum macropodum, Polygonatum cirrhifolium, Polygonatum roseum, Polygonatum longifolium, Polygonatum nudiflorum, Polygonatum oppositifolium, etc.

2. How much is Polygonatum per jin on the market?

The market price of Polygonatum is fairly affordable, generally around 15-20 yuan per jin, while good-quality ones are about 40 yuan per jin. However, due to factors such as production area, market, variety and quality, the price will also fluctuate to some extent. For example, the market price of Chicken-head Polygonatum is around 13-15 yuan per jin, premium Polygonatum is around 18-20 yuan per jin, and premium Polygonatum slices are more than 40 yuan per jin, so for the specific price you still need to inquire at the local market.

3. How to grow Polygonatum for high yields?

1. Land selection and preparation:

Polygonatum likes to grow in shady and moist environments, so when selecting land, try to choose slope land that does not face the sun for planting. After selecting the land, deep plow it and apply 1500-2000 kg of organic fertilizer per mu to prepare for subsequent planting. In addition, to facilitate later drainage and daily management, a ditch about 1.5 m wide with a spacing of about 20 cm between rows can be dug to prepare for later management.

2. Sowing:

(1) Sowing time: around August or March

(2) Sowing method: Polygonatum can be sown by direct seeding or tuber transplanting. Among them, direct seeding is the simplest method; you only need to sow the seeds on the seedbed at reasonable spacing, then cover with a layer of soil. Tuber transplanting means digging out some tubers in March, dividing them into small sections, drying them, then evenly placing them on the soil, then covering with a thin layer of soil and a layer of film or straw, and they will sprout.

3. Seedling-stage management:

To make Polygonatum seeds sprout quickly, remove the straw or film in time before emergence, and when the seedlings are about 9 cm tall, remove crowded or weak seedlings; after one year they can be transplanted.

4. Field management:

(1) Cultivation and weeding: After Polygonatum has grown for some time, weeds will appear, so weeding should be carried out once each in April, June, September and November every year, and soil should be hilled up according to the dryness of the soil to promote seedling growth.

(2) Timely fertilization: Polygonatum does not have high fertilizer requirements, but that does not mean it needs no fertilizer. So when loosening the soil and weeding, calcium fertilizer, farmyard manure, etc. can be applied appropriately. Generally, after the first 3 cultivations, apply 1500 kg of farmyard manure, 5 kg of calcium fertilizer and 50 kg of cake fertilizer per mu to ensure sufficient nutrients.

(3) Pest and disease control: During the growth period, Polygonatum may suffer from leaf blight, black spot, leaf spot, white grubs and other pests and diseases, so control measures must be taken during planting. Generally, leaf blight can be controlled with 500 times dilution of 65% zineb wettable powder; black spot can be sprayed with Bordeaux mixture; white grubs can be irrigated with 75% phoxim emulsifiable concentrate.

5. Harvesting and processing:

Polygonatum is generally harvested in spring and autumn, with the best quality from autumn harvesting. When harvesting, try to dig out the rhizomes, remove the fibrous roots on top, wash off the mud, steam until they appear oily and glossy, then take them out and dry them in the sun or by heat.

Overall, Polygonatum is not expensive and its cultivation technique is simple, so it is generally very easy to grow. If planting for the first time, you can follow the methods above to achieve high yields.
