[0028] A method for improving the germination rate of Polygonatum yunnanensis seeds, comprising the following steps:
[0029] S1: Seed Treatment:
[0030] S1.1: The ripe and plump fruits of Polygonatum yunnanensis were placed in a black plastic bag and fermented at 22°C for 12 days;
[0031] S1.2: manual scrubbing to remove the peel and large pieces of pulp to obtain seeds attached to the pulp;
[0032] S1.3: The obtained seeds are enzymatically treated with cellulase and pectinase, the activity of pectinase is 100000u / g, the dosage is 0.1% of the weight of the pure seeds of Dianhuangjing, and the activity of cellulase is 1000u / g g, the dosage is 0.1% of the weight of the pure seeds of Polygonatum yunnanensis, and the specific steps of the enzymatic hydrolysis treatment include: soaking the seeds of Polygonatum yunnanensis after manual cleaning in the enzymatic hydrolysis solution, heat preservation treatment at a temperature of 15 ° C and a pH of 6 24h.
