Crop management skills after continuous rain
It is common for summer to be hot and rainy, often leading to prolonged periods of continuous rain. Such weather conditions can cause a range of problems for crops, including illness, wilting, and fruit cracking. Therefore, it's crucial to manage the crops properly after rainfall:
1. **Drain Standing Water** – Depending on local conditions, remove field water as soon as possible. If crops have been knocked over due to heavy rain, they should be straightened and supported with soil while draining. Washing away surface sludge helps improve photosynthesis and promotes healthy plant growth.
2. **Loosen the Soil** – Use various methods to cultivate and loosen the soil. This improves soil permeability, enhances root development, and creates a better environment for plant growth.
3. **Prevent Pests and Diseases** – Due to the high humidity and limited sunlight caused by long periods of rain, pests and diseases are more likely to thrive. It's important to monitor and control these issues promptly, applying pesticides when necessary.
4. **Apply Fertilizer After Rain** – Apply an appropriate amount of quick-acting nitrogen fertilizer to flooded crops to replenish nutrients lost due to leaching from rainwater. This ensures adequate nutrient supply and supports rapid plant growth. For example, in spring and summer maize fields, apply 10–15 kg of urea per mu. In cotton fields, use 10 kg of urea and 2.5–3.5 kg of potassium sulfate per mu. For soybean fields, apply 5–10 kg of urea per acre. When treating cotton and soybeans, combine pest control with foliar spraying—use 150–200 grams of potassium dihydrogen phosphate mixed with 30 liters of water and spray directly onto the leaves.
Finally, it's important to note that during the hot and rainy season, the application of nitrogen and potassium fertilizers should be done carefully to avoid nutrient loss. Ensure the fertilizers are evenly distributed into the soil to maximize their effectiveness.
By following these steps, farmers can help protect their crops and ensure better yields even after heavy rains. Taking timely action not only prevents damage but also promotes healthier and more productive plants.
