The screening method can select seeds with large head, full seeds and large specific gravity, at the same time, it can remove some sundries and keep the seeds clean. The screening method is to use a standard pore sieve to remove the withered seeds and leave the full seeds.

2. Seed drying

Choose sunny weather, spread out the seeds in a sunny place, and dry the seeds for 2-3 days for 3-4 hours a day. But need to pay attention to the location to choose the soil ground, do not choose the cement ground or asphalt pavement, otherwise, the ground temperature is higher, easy to burn seeds.

Next, step on it and water it.

6. Seedling emergence management

When emergence, if the temperature is low, about 10-20 days before emergence. In order to promote seedling emergence, a thin film can be covered on the border surface. If the temperature is high, seedlings can emerge in 6-8 days. When the seedlings are about to emerge, the head water should be poured for the second time. Before the cotyledons are straightened, the cotyledons should be watered again to avoid border hardening and affect the air permeability of the soil.
