The planting time of Polygonatum sibiricum is relatively long, and the main cultivation methods are under-forest planting and intercropping in tea gardens.

A plant of Polygonatum sibiricum will produce about 1-2 kilograms in three years, and the higher yields can reach 3-4 kilograms. The specific yield will be determined by factors such as the planting variety and planting management.

Generally, after about three years of planting, a mature Polygonatum sibiricum can reach three or four kilograms, and the plant is relatively complete.

How many years does it take for Polygonatum sibiricum to be harvested?

Polygonatum is generally harvested in spring and autumn, and the quality is better in autumn , because the rhizomes harvested in late autumn and early winter are fat and full, and the quality is the best.

The rhizomes of Polygonatum sibiricum can be harvested after 1-2 years of transplanting, and 3-4 years after sowing seeds. Dig out the rhizomes in late autumn or early spring, clean the soil, and remove the fibrous roots and diseased scars.

Yield and benefits of planting Polygonatum sibiricum

From the perspective of precision planting (i.e. high input and high output), the benefits are very considerable. According to an experienced large-scale Chinese herbal medicine grower, scientific planting of Polygonatum sibiricum, from planting to management to nurturing, requires an average investment of more than 15,000 yuan per mu .

① The planting amount needs to be more than 1,000 kilograms per mu, which costs more than 10,000 yuan according to the current market price.

②Base fertilizer includes commercial fertilizer and farmyard manure, which costs about 2,000 yuan in three years.

③ Standardized land preparation, cultivation and management will cost about 3,000 yuan in three years.

According to those with experience, it is very important to choose the site for precision planting. If the site has good shade and good soil, the cost investment will be relatively lower.

They introduced that after three years of intensive cultivation, it is expected that 4-5 tons of Polygonatum sibiricum fruit can be produced, with an output value of 50,000-70,000 yuan .

Which variety of Polygonatum is good for planting

Polygonatum sibiricum is a perennial herb, with its rhizome used as medicine. Its growth period is relatively long, with a flowering period of May to June and a fruiting period of June to July .

Generally, it takes 2-3 years for the rhizome of Polygonatum to be used for medicinal purposes, while the growth cycle of seed propagation is as long as 5-6 years. There are many types of Polygonatum, which are generally distinguished by shape and taste.

According to its shape, Polygonatum sibiricum can be divided into three types: ginger-shaped Polygonatum sibiricum, chicken-head Polygonatum sibiricum and large Polygonatum sibiricum .

The original plant of ginger-shaped polygonatum is Polygonatum multiflorum, the original plant of Polygonatum acutiloba is Polygonatum sibiricum, and the original plant of large polygonatum is Polygonatum yunnanensis. Among them, ginger-shaped polygonatum has the best quality. According to the taste, it can be divided into sweet polygonatum and bitter polygonatum.

Ginger-shaped Polygonatum, Chicken-head Polygonatum and Large Polygonatum are from different races and have different origins:

Rhizoma Polygoni Multiflori: Mainly produced in southwestern provinces, with Yunnan producing the most;

Polygonatum cyrtonema : Hunan, Hebei, Inner Mongolia and other places. Among them, most of the Polygonatum cyrtonema from Xinglong County, Chengde, Hebei is exported to Japan and South Korea;

Ginger-shaped Polygonatum : has the best quality and is mainly produced in Hunan, Hubei, Guizhou, Anhui, Jiangxi, Chongqing and other places.
