1、 How much is the investment for planting Polygonatum per mu

The investment for planting Polygonatum per mu needs about 3000 yuan to 20000 yuan. The planting of Polygonatum odoratum is divided into extensive planting and fine planting. If the extensive planting is selected, the investment cost is relatively low. According to the planting of 1000 Polygonatum odoratum per mu, the seeds need about 50 kg, that is, about 500 yuan. The labor cost of sorting out the plantation also needs about 500 yuan, so it needs to invest about 1000 yuan a year. If you choose fine planting, the number of plants planted is large, plus the management fee, it will cost at least 7000 yuan. Generally, polygonatum can only be planted for three years, so the investment cost needs to be multiplied by three. Note that if there is no land at home and you need to rent extra land, the cost needs to be added to 500 or 600 yuan

2、 Propagation method of Polygonatum

1. Rhizome propagation: dig rhizomes before and after late autumn or early spring, cut them into sections, keep 3-4 sections on each section, and then prepare the ground and start the border, and plant them according to the row spacing of 22-26cm and the plant spacing of 10-16cm

2. Seed reproduction: after the seeds mature in August, the seeds can be collected in sand and stored in cool pits. In the coming spring, the seeds can be screened out and ready for sowing. Sort out the land, dig ditches after border, and then spread the seeds evenly according to the row spacing of about 12-15 cm, and cover them with a thin layer of soil. Slightly compact, water, cover with a layer of grass, and transplant after a year
