Embodiment 1

[0017] A method for breaking the dormancy of pulsatilla seeds, characterized in that the method comprises the following steps:

[0018] (1) Seed collection: select robust plants without damage by diseases and insect pests, cut off the whole inflorescence with scissors and dry it in the sun when the seeds are fully mature, and screen out plump and fully mature seeds for subsequent use;

[0019] (2) Soak Pulsatilla seeds in 20g / L potassium dihydrogen phosphate solution for 10 hours, then soak them in thiophanate-methyl 500 times solution for 1.5 hours, and finally wash the seeds with warm water at about 23°C;

[0020] (3) Preparation of plant extract: select well-developed plants, collect roots, stems, and leaves of vetiver, cut them into pieces with scissors after drying in the shade, weigh 2, 10, and 4 g of roots, stems, and leaves respectively, and add 100 times Distilled water, soaked at 25°C for 48 hours, filtered through 4 layers of gauze to obtain the stock solution of th...

Embodiment 2

[0023] A method for breaking the dormancy of pulsatilla seeds, characterized in that the method comprises the following steps:

[0024] (1) Seed collection: select healthy plants without damage by diseases and insect pests, cut off the whole inflorescence with scissors and dry it in the sun when the seeds are fully mature, and screen out full and fully mature seeds for subsequent use;

[0025] (2) Soak Pulsatilla seeds in 30g / L potassium dihydrogen phosphate solution for 13 hours, then soak them in thiophanate-methyl 500 times solution for 1.5 hours, and finally wash the seeds with warm water at about 23°C;

[0026] (3) Preparation of plant extract: select well-developed plants, collect roots, stems, and leaves of vetiver, cut them into pieces with scissors after drying in the shade, weigh 2, 10, and 4 g of roots, stems, and leaves respectively, and add 100 times Distilled water, soaked at 30°C for 48 hours, filtered through 4 layers of gauze to obtain the stock solution of th...
