Harvest mature Polygonatum seeds from September to165438+1October, peel them, wash them with clear water, soak them in strong tea water at 30-40℃ for18-30 hours, and take them out to dry.

2. Treatment of fine sand for seed coating

Prepare 5 ~ 10 mg/L ABT rooting powder aqueous solution, 10 ~ 20 mg/L 6- benzylamino adenine aqueous solution and 100 ~ 200 mg/L carbendazim aqueous solution respectively, then mix them evenly in equal volume, and wet the fine sand with the obtained mixed solution, and control the humidity at 30% ~ 200 mg.

3. Sand storage treatment of Polygonatum seeds

Evenly mix the Polygonatum seeds treated in step 1 into the wet fine sand in step 2, and mix 4-8 Polygonatum seeds into each cubic centimeter of wet fine sand, then put them into sacks, put them into a cool warehouse, water them regularly, keep the humidity at 30%-50%, and store them in the sand for 3-4 months.

4. Seeding management of Polygonatum sibiricum seeds stored in sand.

The Polygonatum sibiricum seeds after sand storage in the third step are evenly sown with fine sand on the matrix soil of plastic greenhouse, the sowing thickness is 0.5- 1 cm, and the matrix soil is a mixture of sawdust, dregs and pine bark, and the mass ratio is1:0.5-2: 0.5-2, and then the matrix soil with a width of 3-5 cm is covered on it to form 80.

5. Topdressing management

When Polygonatum sibiricum seeds grow 1 leaf, ventilate the plastic greenhouse every day, water it in the morning and evening, keep the humidity of the substrate soil at 30% ~ 40%, and spray the potassium dihydrogen phosphate compound fertilizer 1 aqueous solution once every other week.

6, weeding and pest management

During the growth of Polygonatum sibiricum seedlings, weeds are removed every other month, mancozeb and phoxim are sprayed every three months to control diseases, and phoxim and trichlorfon are sprayed to control soil pests.
