Embodiment 1
[0020] Example 1 A pre-sowing treatment method for improving the vigor of aged asparagus seeds
[0021] The selected aged asparagus seeds are: champion F1 generation hybrids stored for more than 4 years;
[0022] The pre-broadcast processing method is as follows:
[0023] (1) Remove the large miscellaneous, grainy and damaged seeds through winnowing, and then pass through a sieve to select evenly sized and plump aged seeds; obtain uniformly sized and plump seeds.
[0024] (2) Soak the seeds with different types and concentrations of reagents according to the mass ratio of seeds to reagents 1:10, accelerate germination for 48 hours, then rinse with water and filter dry; 50 grains in a dish, repeated 3 times, placed in an incubator with a constant temperature of 25°C and 12h / h alternating light and dark, and recorded the number of germinated seeds of each treatment every 24h (seeds with a radicle length greater than 1mm were germinated) until the end of germination , Calculate...
Embodiment 2
[0042] Example 2 Germination experiment of aged asparagus seeds treated with different types and concentrations of reagents
[0043] The selected aged asparagus seeds are: champion F1 generation hybrids stored for more than 4 years;
[0044] The pre-sowing treatment method is the same as in Example 1; only change the type and concentration of the reagent for treating the seeds, soak the seeds according to the mass ratio of the seeds to the reagent at 1:10, soak the seeds for 5-15 minutes respectively, then rinse them with clean water, and then rinse them with clean water After 48 hours of germination, the seeds were transferred to the petri dishes of the paper germination bed, 50 grains per dish, repeated 3 times, placed in an incubator with a constant temperature of 25°C and 12h / h alternating light and dark, and recorded every 24h The number of germinated seeds of each treatment (the radicle length is greater than 1mm is the seed germination), until the end of germination, ca...
Embodiment 3
[0050] Embodiment 3 Different ultrasonic power and treatment time are to asparagus seed germination experiment
[0051] The selected aged asparagus seeds are: champion F1 generation hybrids stored for more than 4 years;
[0052] The pre-broadcast processing method is as follows:
[0053] (1) Remove the large miscellaneous, grainy and damaged seeds through winnowing, and then pass through a sieve to select evenly sized and plump aged seeds; obtain uniformly sized and plump seeds.
[0054] (2) Germinate with clean water for 48 hours. After the end, treat the seeds according to the different ultrasonic power and ultrasonic time in Table 3. After the end, rinse them with clean water and transfer them to the petri dishes of paper germination beds, 50 grains per dish, repeat 3 times Put it in an incubator with a constant temperature of 25°C and 12h / h alternating light and dark, and record the number of germinated seeds of each treatment every 24h (the radicle length is greater than...
