Embodiment 1
[0027] 1. Select purple-black iron-coated gold-free fruits (do not pick green to red fruits, which are all immature fruits, and the seeds in fruits in this growth stage are not fully developed, which will affect normal germination).
[0028] The iron-clad gold seed that embodiment 1 adopts is Berchemia lineata The mature fruit of (L.)DC. was used for seeding.
[0029] 2. Rub the fruit picked in step ⑴ while it is fresh, peel off the skin and flesh, and rinse off the residual flesh and juice attached to the seeds with clean water.
[0030] 3. With 0.3%KMnO 4 Solution Soak the seeds treated in step (2) for 30 min for disinfection, and rinse them with clean water.
[0031] 4. Use the sterilized (simple method: put the fine sand into water and boil for more than 25 minutes) and then mix the cooled wet sand with the seeds treated in step (3). The sand humidity is required to be 50%~90%, and the volume ratio of seeds to sand is between 1:3~1:5.
[0032] 5. Put the mixture of see...
Embodiment 2
[0035] The method and iron-coated gold seeds are the same as in Example 1, except that the refrigerated time in step (5) is 90 days.
Embodiment 3
[0037] The method and iron-coated gold seeds are the same as in Example 1, except that the refrigerating time in step (5) is 120 days.
