Abstract: The matrix ratio and the size of the cavern in Polygonatum sibiricum plug seedling technology were studied. Using peat,vermiculite,wood sawdust, garden soil and river sand as the substrate,the optimum substrate for seedling raising of the Polygonatum sibiricum was screened. With the same surface area with different hole mesh point plate,the best hole disc size of the Polygonatum sibiricum were select. The results showed that the effect of peat and peat and vermiculite mixed as acupoint disc breeding substrate was best in all aspects. In the hole disc specifications involved in the test,54 cm×28 cm×40 cm,72 hole and volume 40 cm³ were the best seedling plate size.

Key words: Polygonatum sibiricum, hole disc breeding, matrix ratio, seedling plate size
