First, how to select the seeds of Polygonatum odoratum?

The stem of Polygonatum odoratum should be stout, the bud tip is neat, slightly concave, yellowish-white, each section has 1-2 nodes, and the whisker root should be more. Planting rhizome with terminal bud is one of the key techniques to ensure high quality and high yield of Polygonatum odoratum. The rhizome without apical bud or the rhizome with thin and thin bud tip protruding sharply to the outside is not suitable for seed, so the quasi-rhizome has low germination rate, poor vitality, low yield and quality. The rhizome of Polygonatum odoratum with no apical buds and no adventitious buds did not produce seedlings in the first year, but only some weak seedlings appeared in the second year; some had adventitious buds, but the buds were small, without apical dominance, the emergence rate was low, and the growth potential was weak.

2. Seedling raising methods of Polygonatum odoratum seeds.

1. Land selection and preparation

The slightly acidic sandy loam with deep soil layer, good drainage and sunny direction should be selected and turned more than 30 cm deep. At the same time, 3000-4000 kg of farm manure should be applied per mu as base fertilizer and raked flat to form a high border with a width of 1.3 cm.

2. Seed germination

Before sprouting treatment, the seeds of Polygonatum odoratum were soaked in cold water for 24 hours. After the seeds were fully mixed with wet sand according to the volume ratio of 1 ∶ 3, they were put into wooden boxes to accelerate germination. The changes of temperature and humidity in the box were checked every 2-3 days, and the seeds were poured every 5-7 days. Samples were cut with a knife every 10 days to check the growth and development of seed embryos.

3. Planting

Generally in early October to late October, choose cloudy or sunny days to plant, when planting in the border according to the row spacing of 30 cm to open 15 cm deep ditch, and then the seed stem according to the plant spacing of about 15 cm in the ditch, then covered with rotten manure, and then covered with a layer of fine soil to level with the border surface.

4. Field management

To often check the border cover, found that the lack of timely cover, in order to keep the border soil often moist. Remove the mulch in time when the seedlings emerge, and do a good job of weeding. The annual seedlings should be covered with cold protection from withering to freezing, covering leaves, grass or dung to ensure that the seedlings survive the winter safely.
