1, outdoor sun seed germination method: should be carried out in sunny days. Will be planted ginger placed in front of the house on the ground, storage time should follow the principle of "early release and late harvest". At the same time, the sun should be exposed to ensure that the water in the planted ginger is reduced and the temperature of the ginger body rises, so that the seed buds sprout. Sun 15 to 20 days or so, planted ginger in the seed bud 0.5 cm or so can be planted. 2, greenhouse germination method: to understand not only to accelerate the ginger germination, but also accelerate the germination. Therefore, if you accelerate germination in the greenhouse, you can use temperature regulation to help us achieve this goal. The operation of greenhouse germination is also very simple:Place the ginger on the straw in the greenhouse, cover it with straw, and then regulate the temperature. The temperature for ginger germination is usually 15 to 30 degrees. If you want to cultivate short and strong buds, it is better to keep the temperature at 22~25 degrees. In general, the temperature should reach about 20 degrees for the first 10 days of greenhouse germination and keep the temperature at 22~28 degrees after 10 days. After observing the ginger germination, the temperature should be reduced to almost the outdoor temperature, and the seeds can be sown in about 3 days.
