After detoxification, the sweet potato exhibits vigorous growth with multiple branches, producing neat and smooth tubers free from cracks or black spots. The skin color is pure, and the yield can reach 4,000 to 5,000 kilograms per mu. This variety not only boosts yield but also reduces nitrogen fertilizer use by 30%, while showing strong resistance to diseases like black spot and black rot. Below are the key cultivation techniques for this high-yield variety:
1. **Apply Base Fertilizer**: Prioritize organic manure along with phosphorus and potassium fertilizers. Avoid excessive nitrogen to prevent overgrowth and ensure balanced development.
2. **Mounding (Ridge Planting)**: Sweet potatoes thrive in environments with a significant day-night temperature difference. Mounding increases air circulation and light exposure, creating an ideal microclimate that promotes faster tuber growth.
3. **Optimize Planting Density**: Increasing planting density is essential for maximizing yield. Detoxified sweet potatoes grow uniformly without empty spaces, making it suitable for close planting. For yields above 10,000 kg per mu, the recommended density is 4,500–5,000 plants per mu in spring and 5,000–6,000 in summer.
4. **Effective Weed Control**: Apply herbicides such as acetochlor (0.2–0.3 kg per mu) shortly after planting, or pre-emergence herbicides when weeds have three true leaves (40–80 grams per mu). This helps eliminate weeding efforts throughout the growing season.
5. **Regulate Growth**: Detoxified seedlings tend to grow vigorously, so controlling their growth is crucial. When vines reach about 45 cm, spray a solution of paclobutrazol (200 mg/kg) at 50 kg per mu to enhance tuber formation and improve yield.
6. **Avoid Vine Turning**: Turning the vines is a common practice but often leads to reduced yield by more than 10%. It damages the foliage, reducing photosynthesis and ultimately affecting root development. Therefore, it's best to avoid this practice altogether.
By following these techniques, farmers can achieve higher yields, better quality tubers, and more sustainable farming practices.
