Key points of high-yield cultivation of sweet potato

1, soil preparation and fertilization

Sweet potato is suitable for planting in sandy loam with deep soil layer, loose and fertile soil and good drainage. Usually, before planting, the soil can be deeply turned to a depth of 20-25 cm, and 5000 kg of manure and 25-50 kg of compound fertilizer can be applied per mu.

2. Sowing and raising seedlings

Before sowing sweet potatoes, accelerate germination. Soak the full seeds in clear water 10- 12 hours, take them out and put them in a damp paper towel until most of the seeds are white. Sow them on the ground and put 1-2 seeds in each hole.

3. Post-planting management

Sweet potatoes should be interplanted and replanted after they grow. After the sweet potato is planted, the manure can be applied once. When the soil is slightly dry, intertillage weeding can be carried out. When the main vine of sweet potato grows to 18-24 leaves, it can be topped and cored. In the process of sweet potato growth, the lateral vines should be removed and only the main vines should be kept. Usually, sweet potatoes can be harvested 5-6 months after sowing.
