White sweet potato is a nutritious and unique vegetable that is widely grown in southern China. However, how to select suitable varieties, master appropriate planting time and scientific cultivation techniques are the key to ensuring yield and quality. This article will introduce in detail the planting and maintenance skills of white sweet potatoes to help readers better master this technology.

1. Selecting high-quality seedlings of white sweet potatoes requires selecting seedlings that are strong, disease-free, and have strong growth potential. You can choose to cultivate your own or purchase high-quality seedlings on the market.
2. Prepare fertile soil White sweet potatoes like warm and humid environments and prefer fertile and well-drained soil. Add organic fertilizer or chemical fertilizer to the land and carry out deep plowing.

3. Choose the appropriate planting time. White sweet potatoes are suitable for planting in three seasons: spring, summer and autumn. The most suitable times are spring from March to May and autumn from September to November.
4. Properly grasp the planting depth. The planting depth of white sweet potatoes should be controlled at about 5 - 6 centimeters. If the soil is too wet, the depth can be increased appropriately.
5. Grasp the appropriate distance between plants. The distance between plants should be reasonable, generally about 25 - 30 cm, to ensure sufficient space between plants and avoid competition with each other during future growth.

6. Pay attention to preventing and controlling pests and diseases. White sweet potatoes are vulnerable to pests such as vegetable moths and aphids, and timely prevention and control measures need to be taken. Biopesticides or chemical pesticides can be used for prevention and control.
7. Reasonable watering of white sweet potatoes requires maintaining a certain humidity, but it cannot be over-watered. The amount and frequency of watering should be flexibly adjusted according to actual conditions.
8. Timely weeding and grass grow together, and white sweet potatoes will also be affected by weeds. Timely weeding can help ensure the growth and yield of white sweet potatoes.
9. Reasonable fertilization The growth of white sweet potatoes requires sufficient nutrients, and fertilization can be used to increase yields. However, the amount of fertilization also needs to be controlled. Excessive fertilization will lead to the breeding of pests and diseases.
10. Pay attention to harvest time. Harvest time is the key to affecting the yield and quality of white sweet potatoes. Pick white sweet potatoes in time when they are ripe without undue delay.
11. Do a good job in preservation. White sweet potatoes can be stored and preserved after picking. You can choose to store them in ways such as ventilation, drying, and light.
12. Appropriate pruning The growth of white sweet potatoes requires appropriate pruning to promote nutrient distribution and ventilation during the growth process. However, the method and timing of pruning need to be selected based on actual conditions.
13. Pay attention to preventing frost. White sweet potatoes like a warm environment and are not resistant to cold. In the cold winter season, attention should be paid to timely insulation to prevent the impact of frost.
14. Pay attention to cleaning up residual branches and leaves. During the cultivation process, white sweet potatoes will produce a large number of residual branches and leaves, which need to be cleaned in time. This helps maintain a clean growing environment and reduces the breeding of pests and diseases.
15. The planting and maintenance of white sweet potatoes require the mastery of certain skills and methods. Appropriate planting time, fertilizer use, pest and disease control, etc. are all keys to affecting yield and quality. I hope this article will inspire readers so that they can better grow white sweet potatoes.
