When is the best time to raise sweet potato seedlings?

Sweet potato seedlings are generally raised around March.

The seedling raising time of sweet potato depends on the planting area and season, but it is generally concentrated in March. In spring, seedlings are usually raised before and after the sting. The south begins in February, and then the north usually ends before Tomb-Sweeping Day.

Because the temperature is low when raising seedlings, hotbeds are usually the main ones, so we should pay attention to heat preservation after starting raising seedlings. Moreover, the seedling raising time should be reasonably controlled according to the planting time. Seedling raising should start 4-5 weeks before planting.

As the saying goes: "Sweet potato crops in one season and a half" is summed up by the working people in the days when their living materials are insufficient. Now that living conditions are good, no one takes sweet potatoes as staple food. But life was hard in the past, and sweet potato, as a life-saving food, once supported that generation of working people.

Technical requirements:

The reason why China has made such brilliant achievements in sweet potato cultivation is not only related to China's vast territory and suitable climate, but also related to the innovative technology and rich experience accumulated by working people in the long-term sweet potato cultivation process. For example, high ridge cultivation technology, inverted planting technology, vine lifting and seedling turning technology and so on.

Among them, kang bed seedling raising is also a sweet potato seedling raising practice invented and created by working people in the long-term sweet potato breeding process, and valuable practical experience has been accumulated in this process.
