Embodiment 1
[0043] A method for improving the germination rate of Daphne tangutica seeds, comprising the steps of:
[0044] (1) Pretreatment: pick ripe Tangutia daphne fruit, remove the peel and pulp, choose 50 seeds from the obtained seeds, and dry them for later use;
[0045] (2) primary disinfection: sterilize the seeds obtained in step (1) with 5% potassium permanganate solution for 8min, and rinse with distilled water;
[0046] (3) Primary stratification: Mix the river sand with a water content of 15% and the seeds obtained in step (2) at a ratio of 5:1 and place them in a germination box, and place them in a refrigerator at 5°C for 25 days;
[0047] (4) Seed soaking: the seeds obtained in step (3) are washed with distilled water, and then soaked in warm water at 25°C for 48 hours;
[0048] (5) acid etching: the seeds obtained in step (4) were seed-dressed for 45min with 2.0mol / L sulfuric acid solution, rinsed with distilled water and dried naturally;
[0049] (6) Secondary disinfe...
