1、 Seedling raising time

The seedling raising time is selected from the middle of February to the middle of April. According to the regional differences, the seedling raising time is somewhat different. In the areas biased towards the north, the seedlings should be raised around April because the climate is relatively cold. In the areas biased towards the south, the seedlings can be raised around the middle of February because the climate picks up quickly

2、 Seedbed selection

If you choose flowerpot for seedling raising, you should first prepare loam and disinfect it in advance to ensure that there is no possibility of diseases and pests. If you choose to plant seedlings, you should find a sunny place to ensure that the terrain is flat, the soil should be loose and soft, and have certain nutrition. It should not be too thin or too thick. It is appropriate to keep it at about 5-8 cm. In order to ensure good nutrition, you should also apply certain fertilizer, which is required to be organic fertilizer after ripening

3、 Treated seed potato

Select the seed potato with full growth. It is required to be free of diseases and insect pests, keep uniform size, and preferably be of moderate size. After selection, it can not be sown immediately. It needs to be treated. In order to prevent it from carrying bacteria, it can be soaked in warm water for about 10 minutes or with medicine

4、 Seeding and seedling raising

Sow the seed potato into the loam, and then pay attention to the maintenance method. The thickness of the covering soil should be the same to ensure that the seedling emergence is uniform and tidy
