[0017] Example 1:
[0018] Collect fresh and ripe fruits in mid-October, wrap the fruits in wet paper towels with a relative humidity of 70%, and place them in a closed container under dark indoor conditions for post-ripening treatment for 4 days, then shelling to obtain seeds, with a mass fraction of Soak the seeds in 0.1% potassium permanganate solution for 2 hours, and dry them in the shade for later use. Spray the substrate with dixon solution diluted 2000 times, leave it for 3 days, pour clear water on the 4th day, and then count the seeds by quartering, spread the soaked seeds in the substrate, and cover a 1.8m above the substrate. The layer of shading net with a shading rate of 90% is watered or sprayed for moisturizing every day; the composition and mass ratio of the substrate are: ceramsite: perlite: vermiculite: river sand: peat soil = 1:2:2 :2:4; The germination temperature of seeds is 10~29℃.
[0019] The germination begins after 50 days, and the germination rate reac...

[0020] Example 2:
[0021] Collect fresh and ripe fruits in mid-October, wrap them in wet paper towels with a relative humidity of 90%, and place them in a closed container under dark indoor conditions for post-ripening treatment for 5 days, and then husk to obtain seeds with a mass fraction of 0.3 Soak the seeds in% potassium permanganate solution for 2 hours and dry them in the shade for later use. Spray the substrate with dixon solution diluted 3000 times, leave it for 3 days, pour clear water on the 4th day, and then count the seeds by quartering, and sprinkle the soaked seeds on the substrate, covering a 2 meter area above the substrate. The layer of shading net with a shading rate of 90% is watered or sprayed for moisturizing every day; the composition and mass ratio of the substrate are: ceramsite: perlite: vermiculite: river sand: peat soil = 1:2:2 :2:4; The germination temperature of seeds is 10~29℃.
[0022] The germination began after 45 days, and the germination rate ...

[0023] Example 3:
[0024] Collect fresh and ripe fruits in mid-October, place the fruits at room temperature and ventilate without post-ripening treatment, then hull them to obtain seeds, soak the seeds with 0.2% potassium permanganate solution for 2 hours, then sow after drying in the shade For the processed substrate. Three days before picking the fruit, spray the substrate with dixon solution diluted 2500 times, pour clear water on the 4th day, and then count the seeds by quarters. Sprinkle the soaked seeds in the substrate, 2 meters above the substrate Cover a layer of shading net with a shading rate of 90%, watering or spraying for moisturizing every day; the composition and mass ratio of the substrate: ceramsite: perlite: vermiculite: river sand: peat soil = 1:2 :2:2:4; the germination temperature of seeds is 10~29℃.
[0025] The germination begins after 40 days, and the germination rate reaches 70% after 4 months.
