1, temperature:

Sweet potato likes warm environment, and is not afraid of cold or cold. The suitable growth temperature is between 22 and 30, and the growth will stop when it is lower than 15. Different growth periods have different requirements for temperature.

2, fertilization:

Sweet potato should meet the demand of fertilizer during its growth. Appropriate amount of nitrogen fertilizer can promote the growth and photosynthesis of leaves, stems and branches, but it should not be excessive.

3. Soil:

Sweet potato should mature in sandy soil and sandy soil with deep soil layer, rich organic matter, loose soil and good ventilation and drainage performance.

Sweet potato growth process

From planting sweet potatoes to potted plants, it takes about 60-70 days for spring sweet potatoes and 40 days for sweet potatoes. During this period, the growth of stems and leaves is very slow, and the root system develops rapidly, which is a period dominated by fiber roots.

2. In the medium term:
