Embodiment 1
[0039] Embodiment one: soaking frequency and time are preferred
[0040] 1. Select 1,900 seeds of Chonglou yunnanensis that were fresh and mature in the same year, uniform in size, in the same state, and stored for the same storage time, and divided them into 19 groups, with 100 seeds in each group. The weight of seeds was not significantly different within and between groups. Seed germination was performed using the method described above. Among them, the soaking time is " / ", indicating that the soaking has not been carried out; the concentration of sodium tungstate is 0.1%, the concentration of hydrogen peroxide is 2%, the concentration of potassium nitrate is 19mmol / L, and the concentration of gibberellin is 500mg / L , the concentration of mercury is 0.1%. The specific operating parameters of each group are shown in Table 1.

Embodiment 2
[0054] Embodiment two: preferred soaking sequence
[0055] 1. Select 1,100 seeds of Chonglou yunnanensis that were fresh and mature, uniform in size, in the same state, and stored for the same storage time in the same year, and divided them into 11 groups, with 100 seeds in each group. There was no significant difference in seed weight within each group and between groups. Using the method above, adjust the order of soaking for seed germination. The concentration of sodium tungstate is 0.1%, the concentration of hydrogen peroxide is 2%, the concentration of potassium nitrate is 19mmol / L, the concentration of gibberellin is 500mg / L, and the concentration of mercury is 0.1%.
[0056] Among them, the number X is used to represent the Xth soaking, for example: the soaking sequence is: 12345, which means that the first soaking, the second soaking... until the fifth soaking is carried out in sequence; for another example, the soaking sequence is : 13452, indicating that the soaking...
Embodiment 3
[0068] Embodiment three: the concentration of soaking medicinal liquid is preferred
[0069] 1. Select 1,300 seeds of Chonglou yunnanensis that were fresh and mature in the same year, uniform in size, in the same state, and stored for the same storage time, and divided them into 13 groups with 100 seeds in each group. There was no significant difference in seed weight within each group and between groups. Seed germination was performed using the method described above. Wherein, the concentrations of soaking liquids in each group are shown in Table 7.
[0070] Table 7 Concentration of soaking liquid in each group
[0071]
[0072] 2. Calculate the average germination rate of the above-mentioned groups at 30 days, 45 days, 60 days, 90 days and 180 days respectively. Among them, seeds that have not germinated within 180 days are counted as germination failure; 180 days with a germination rate lower than 90% are counted as program failure. The specific results are shown in T...
