[0032] A method for promoting the germination of Desmodium spp. seeds, comprising the following steps:
[0033] Step 1, soaking the seeds of Desmodium sativa with polyethylene glycol solution;
[0034] Step 2. Place the Desmodium sativa seeds obtained in Step 1 in the culture medium and cultivate them under the conditions of constant temperature and alternating light. conditions for 12 hours.
[0035] The described method for promoting the germination of Desmodium sativa seeds, before the step 1, the seeds of Desmodium sativa are first divided into three grades, and then the seeds of grade I, grade II and grade III are respectively treated with 20% polyethylene glycol by mass fraction The solution was soaked for 44 hours, 36 hours and 20 hours, and the temperature of the solution was kept at 20°C during the soaking process;
[0036] Among them, Grade I seeds are 1.8-2.3mm long, 1.2-1.7mm wide, and the thousand-grain weight is greater than 1.80 grams; Grade II seeds are 1.5-2...

[0049] A method for promoting the germination of Desmodium spp. seeds, comprising the following steps:
[0050] Step 1, soaking the seeds of Desmodium sativa with polyethylene glycol solution;
[0051] Step 2. Place the Desmodium sativa seeds obtained in Step 1 in the culture medium and cultivate them under the conditions of constant temperature and alternating light. conditions for 12 hours.
[0052] The method for promoting the germination of Desmodium sativa seeds, before the step 1, the seeds of Desmodium sativa are first divided into three grades, and then the seeds of grade I, grade II and grade III are respectively polymerized with a mass fraction of 20%-30%. Soak in ethylene glycol solution for 48 hours, 40 hours and 24 hours, and keep the solution temperature at 30°C during the soaking process;
[0053] Among them, Grade I seeds are 1.8-2.3mm long, 1.2-1.7mm wide, and the thousand-grain weight is greater than 1.80 grams; Grade II seeds are 1.5-2.3mm long, 1.0-1.7mm ...

[0066] A method for promoting the germination of Desmodium spp. seeds, comprising the following steps:
[0067] Step 1, soaking the seeds of Desmodium sativa with polyethylene glycol solution;
[0068] Step 2. Place the Desmodium sativa seeds obtained in Step 1 in the culture medium and cultivate them under the conditions of constant temperature and alternating light. conditions for 12 hours.
[0069] The method for promoting the germination of Desmodium sativa seeds, before the step 1, the seeds of Desmodium sativa are first divided into three grades, and then the seeds of grade I, grade II and grade III are respectively polymerized with a mass fraction of 20%-30%. Soak in ethylene glycol solution for 45 hours, 38 hours and 22 hours, and keep the solution temperature at 25°C during the soaking process;
[0070] Among them, Grade I seeds are 1.8-2.3mm long, 1.2-1.7mm wide, and the thousand-grain weight is greater than 1.80 grams; Grade II seeds are 1.5-2.3mm long, 1.0-1.7mm ...
