Propagation method of Polygonatum polygonatum

1. Rhizome propagation: Polygonatum rhizome propagates in late autumn or early spring to dig underground rhizome, select the young part of the apex and cut into several segments, each section has 3 or 4 nodes, the wound is slightly dried and planted in the whole border, and then slightly suppressed and watered after covering the soil to keep the soil moist before emergence.

2. Seed propagation: Polygonatum seeds were treated with sand storage immediately after they matured in August, and the seeds were screened out in late March of the second year. The seeds were evenly sown in the shallow ditch on the border surface, watered and covered with a layer of grass after covering the soil, and the cover grass was removed before emergence. The seedlings can be planted properly in the dense place, and transplant after one year.

Planting method of Rhizoma Polygonatum

1. Land selection and land preparation: Polygonatum polygonatum is planted in moist and shaded plots, and the soil should be loam or sandy loam with loose texture and good water retention, combined with 2000 kg of farm manure per mu to be turned into the soil as base fertilizer, and then raked fine and leveled to make the border.

2. Seedling transplanting: Polygonatum polygonatum transplanting in the north is mostly carried out at the beginning of April, digging holes according to row spacing of 30 cm and plant spacing of 15 cm on the whole planting plot, and then planting the seedlings into the hole, 2 plants in each hole, covering the soil and compacting, watering once.

3. Intermediate ploughing and weeding: during the growth of Polygonatum polygonatum plants, ploughing and weeding should be carried out frequently, once a year in April, June, September and November, and shallow hoeing should be carried out so as not to hurt the roots, and properly cultivate the soil to promote strong plants, and pull weeds in the later stage.

4. Reasonable topdressing: Polygonatum polygonatum combined with intertillage for topdressing every year, applying 1000-1500 kg / mu of high-quality fertilizer for people and animals, and 1200-1500 kg of high-quality farm manure before winter, and mixed with 50 kg of superphosphate and 50 kg of cake fertilizer.

6. remove flowers: Polygonatum flowers and fruits will consume a lot of nutrients and affect the growth of rhizomes. Therefore, it is necessary to pick the flower buds in time before the formation of flower buds to promote the concentrated transfer of nutrients to the rhizome of the harvest to increase yield.

7. Prevention and control of diseases: Polygonatum leaf spot was controlled with 65% zinc wettable powder, black spot was sprayed with 100 Bordeaux solution, grub was mixed with 75% phoxim EC according to seed amount of 0.1% or irrigated with 90% trichlorfon 1000 times during the occurrence period.

8. Harvest and processing: Polygonatum rhizome propagated in 2-3 years after planting, seeds propagated in 3-4 years after planting, can be harvested in spring and autumn, but the harvest quality is good in autumn, the yield per mu is 400-500 kg, and the high yield can reach 600 kg.
