Summer high temperature rainy tomatoes prevent defeat
In the summer, high temperatures and heavy rainfall can cause tomatoes to lose their weight and quality. To prevent this, it's important to implement effective measures during the hot season. One key approach is to change the cultivation method. Instead of flat ridge planting, switch to raised bed cultivation. This helps protect the tomato roots from waterlogging and soil contamination. If plants are already grown in a flat area, you can gradually mound soil around the base and create ridges. This process should be done 2 to 3 times, ensuring that the root system remains healthy without being over-exposed.
Another important step is to adjust pruning techniques. When the first flower cluster forms, the first side shoot below the second cluster should replace the main stem. Once the plant has two or three clusters, choose one side to become the new main stem. By continuously removing the growing tip, you encourage the plant to renew itself and grow more vigorously, which helps maintain fruit set and prevents the plant from becoming weak or "defeated."
Proper watering and fertilization are also crucial. Water the plants every 7 days, and apply nitrogen-based fertilizer like urea or ammonium nitrate every 15 to 20 days. Use about 5 kg per acre. Additionally, spray a solution of potassium dihydrogen phosphate on the leaves to strengthen the plant and promote compact growth, avoiding excessive elongation.
Pest and disease control must be timely. During summer, tomato crops are often affected by fungal diseases and viral infections. A mixture of carbendazim and zinc sulfate diluted at a ratio of 1:1 and sprayed at 500 times concentration can help manage fungal issues. For viral diseases, spray a 0.1% to 0.3% potassium permanganate solution every 7 to 10 days before symptoms appear to provide early protection.
Finally, ensure proper drainage. Tomatoes are sensitive to waterlogging, so avoid watering during midday heat. Water in the early morning or late evening, and after irrigation, make sure to drain excess water from the field by clearing ditches promptly. These practices will help maintain plant health and improve yield during the challenging summer months.
