Polygonum multiflorum (He Shou Wu) planted for three years yields about 2000 kg of fresh tuberous roots per mu

AbstractAfter three years of cultivation, Polygonum multiflorum (He Shou Wu) is harvested. Under conventional cultivation methods, the yield of fresh tuberous roots is about 2000 kg per mu, while the yield of dried goods is about 400-600 kg per mu. At present, Polygonum multiflorum in China is mainly produced in Guangdong and Henan, with relatively large output and superior quality.

I. Three-year Polygonum multiflorum yield per mu

Polygonum multiflorum is grown in a relatively wide range of areas, and wild resources are relatively abundant. A small number of provinces and regions cultivate it. According to statistics, Polygonum multiflorum has relatively large output and good varieties in Henan and Guangzhou, with fresh tuberous roots generally yielding about 2000 kg per mu and dried goods about 400-500 kg, with high yields reaching about 600 kg.

II. Market prospects of Polygonum multiflorum

1. Polygonum multiflorum is also called Zi Wu Teng, Ye Jiao Teng and Duo Hua Liao, among other names. Polygonum multiflorum is a perennial twining vine plant, and its root tubers can be used as medicine. It has effects such as nourishing blood, activating collaterals, calming the nerves and detoxifying. Prepared He Shou Wu can also tonify essence and blood, strengthen tendons and bones, tonify the liver and kidneys and darken beard and hair. It is a common valuable and fine Chinese medicinal material. Its cultivation areas are relatively wide, such as East China, Central China, South China, Sichuan, southern Shaanxi, southern Gansu, Guizhou and Yunnan.

2. The price of Polygonum multiflorum is greatly affected by labor costs and resources. Wild Polygonum multiflorum is mainly distributed in Sichuan, Guizhou, Guangdong, Guangxi, Yunnan, Hubei and Hunan, among other provinces. It is a perennial twining herb, generally growing underground for 3-5 years, and those with long growth periods can reach more than 10 years. Wild Polygonum multiflorum resources are limited. As people have continued to dig and harvest the resources, the resources have become fewer and fewer. In addition, because more rural laborers go out to work, the number of people digging Polygonum multiflorum has decreased, and the output is declining by about 20% each year.

3. In recent years, the price of Polygonum multiflorum has risen somewhat, but there has not been large-scale production for cultivation, nor are there good planting techniques. The yield of dried products is about 500 kg per mu. Seedling costs, fertilizer, trellis costs and labor require an investment of more than 3000 yuan per mu. If calculated at a recent price of about 21 yuan per jin, it is harvested only once every three years, and the economic return is too low. Apart from poor areas in Guizhou and Yunnan, no other places carry out large-area planting.

4. Because the planted quantity is not large, natural inventory is naturally small. According to reports, prices in Yunnan and Guizhou have been relatively high in recent years, sales are good, and they are almost sold out. In the old production area of Deqing, Guangdong, the local varieties are excellent and the quality is high, but the output is small. They are generally used for export and are in short supply. From the current market perspective, its market prospects are still quite good.
