Reasons and Prevention of Rotten Cultivated Potatoes Covered with Rice Straw

Straw-covered and cultivated potato is an innovative technique for growing potatoes in a single season, offering significant benefits such as saving time and labor, maintaining moisture and warmth, reducing weeding, and increasing overall efficiency. This method holds great importance for boosting farmers' income, but proper sowing practices are essential. During high-temperature periods or the rainy season, there's a higher risk of seed rot, with some farms experiencing losses of up to 20%. The causes of this problem and effective prevention measures are outlined below. **Causes of Seed Rot** 1. **Inadequate Sterilization**: Potato cuttings that are not properly disinfected can lead to infection. Cutting allows oxygen to enter the seed potato, stimulating amylase activity and promoting sprout development. Seed pieces under 25g require minimal cutting, while those over 35g should be cut vertically. However, improper disinfection delays healing and increases the risk of rot. 2. **Excess Moisture After Germination**: If seed potatoes are not fully dried after germination, excessive moisture can cause decay. 3. **Poor Ventilation During Germination**: Insufficient air circulation leads to heat buildup, causing internal damage and sprout death. 4. **Poor Drainage in Fields**: Inadequate drainage systems result in waterlogging, which promotes bacterial growth and seed rot. 5. **Direct Contact with Chemical Fertilizers**: Fertilizers can burn the seed potatoes if they come into direct contact. 6. **Incorrect Planting Orientation**: When cut pieces are laid flat on the soil surface, the buds face downward, making it difficult for roots to absorb water and nutrients, leading to rot. **Control Measures** 1. **Improve Field Drainage**: After harvesting rice, immediately create ditches according to the drainage direction. The main path should be 2 meters wide, and the ditch 0.3 meters wide. Ensure the field has a slight slope to prevent water accumulation. Dig "Three Ditches" (main, secondary, and tertiary) to ensure proper drainage. 2. **Proper Cutting and Disinfection**: Use virus-free seed potatoes and cut large tubers into triangular or square pieces with 1–2 healthy buds. Disinfect knives and cutting boards with 3% potassium permanganate solution. Soak seed potatoes in a mixture of Mn-Zn urea, hydrosemicin, and antibiotics before drying in a cool, ventilated area. 3. **Correct Germination Practices**: Germinate sterilized seed potatoes in greenhouses, grass beds, or sand beds. Soak whole tubers in 4–5 mg/L gibberellin for 10–15 minutes. Maintain good ventilation and moisture levels during germination. Select tubers with 1 cm sprouts and allow them to harden for 2–3 days before planting. 4. **Avoid Direct Fertilizer Contact**: Do not place chemical fertilizers directly near seed potatoes. Keep them at least 8–10 cm away or apply them in shallow trenches between rows. 5. **Correct Planting Technique**: Place seed pieces on their side so the eyes are parallel to the ground. Bury them about one-third deep so the buds are level with the soil surface. This helps roots grow quickly and access nutrients efficiently. This method not only improves yield and quality but also reduces labor and resource use, making it a valuable practice for modern agriculture. By following these guidelines, farmers can significantly reduce the risk of seed rot and increase their profitability.
