The thousand-grain weight of the seed is 12.5 grams, and the germination rate is about 60-80%.
Before sowing, the seeds must be treated, mainly with boiling water, that is, put the selected seeds into a container, pour in boiling water 2-3 times the volume of the seeds, stir evenly for 1 minute, then place in cold water for 24 hours, and wait for the majority After the seeds are swollen, take them out for sowing.
