specific Embodiment approach 1
[0015] Specific implementation mode one: the processing method that the Northeast maple seed breaks dormancy and emerges in the same year according to the following steps in this embodiment:
[0016] 1. Soak the Northeast maple seeds to remove rotten and immature seeds. From October 1st to October 15th of the first year, soak the Northeast maple seeds in water at 45-50°C until they are naturally cooled to room temperature. After 24 hours, re- Change the water and repeat soaking 3 to 7 times;
[0017] 2. Soak and sterilize the soaked seeds with potassium permanganate solution for 1 hour, take out and clean the seeds with clear water after soaking and sterilizing; the mass concentration of the potassium permanganate solution is 0.2%;
[0018] 3. Mix the cleaned seeds and wet river sand in a volume ratio of 1: (2~4) to obtain a mixture of seeds and river sand, and then place them in a ventilated container to keep the water in the river sand constant and The temperature of the ri...
specific Embodiment approach 2
[0025] Embodiment 2: This embodiment is different from Embodiment 1 in that: the mass percentage of water in the wet river sand described in step 3 is 60%. Other steps and parameters are the same as those in the first embodiment.
specific Embodiment approach 3
[0026] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the air-permeable container described in step 3 is a clay flower pot. Other steps and parameters are the same as those in Embodiment 1 or 2.
