The planting method of sweet potato is as follows

The cultivation of sweet potato can start with methods such as accelerating germination, sowing management, topdressing, pruning and coring, and controlling flowering.

1, germination method

When planting sweet potatoes, accelerate their germination. You can choose fully mature potatoes with full seeds, and then put them in an environment with a temperature of about 25-30℃ to promote their rapid germination. And you have to cut the seed potato into small pieces with a sterilized sharp knife to ensure that each potato piece contains 1-2 small buds.

2. Sowing management

Sweet potato is suitable for growing in fertile sandy loam. When planting sweet potatoes, we should first apply decomposed organic fertilizer and cake fertilizer to the soil, then bury the sweet potatoes in the soil and cover them with plastic film. After about half a month, the sweet potato will sprout. At this time, the plastic film should be uncovered.

3. Topdressing

Sweet potato is a fertilizer-loving plant, and it needs sufficient nutrients during its growth. When cultivating sweet potatoes, dilute manure should be applied once after the plants emerge to speed up their growth, while in the season when sweet potatoes grow vigorously, phosphate fertilizer and potash fertilizer should be applied 2-3 times to improve their yield.

4. Trimming and coring

When cultivating sweet potatoes, we should cut the branches that grow too long to avoid the loss of redundant nutrients, and cut off the yellow leaves and diseased branches of sweet potatoes in time to prevent the situation from deteriorating and make them grow tubers. After the sweet potato blooms, pick the flowers in time.

Step 5 control the king

In many sweet potato fields, because of too much water and fertilizer, stems and leaves grow vigorously, and potatoes are not produced or small. In the growing period, there are many methods to control the flourishing growth, such as lifting vines, turning vines, removing the heart, chemical control and so on. Generally speaking, chemical control is labor-saving.
