1, dry seeds: the seeds of snake beans belong to wood species, and their shells are hard and difficult to germinate. The germination rate of seeds can be improved by accelerating germination in advance. After selecting suitable seeds, they will be exposed to the sun for a few days, about 1-2 days.

2. Hot water scalding: Hot water scalding should be carried out after the seeds are dried, which can not only improve the germination rate of the seeds, but also remove the germs outside the seeds. Prepare a container, put hot water at about 55 degrees Celsius, soak the seeds in water, and stir while soaking to prevent the seeds from being burned.
