In the early spring rice breeding season, low-temperature cold waves or prolonged rainfall often occur. If the water level in the paddy fields is not properly managed, the seedlings may become weak, their root absorption capacity may be reduced, and the balance between the upper and lower parts of the plant may be disrupted. This weakened state makes the seedlings more susceptible to pathogen invasion, leading to diseases such as rot. To prevent these issues, the following measures are recommended:
Proper drainage and ventilation in the paddy field is essential—not only for water permeability, which helps with seed germination and emergence, but also for air circulation, allowing the seedlings to develop strong roots and grow vigorously. This can effectively prevent root rot. The process involves first preparing the field by making it fine, digging ditches, and creating small mounds. Apply sufficient base fertilizer, break up the soil thoroughly, and level it out after soaking the field with water.
Timing is crucial when it comes to sowing. It's important to choose the right planting date based on the seedling age to avoid rot. Rice seeds typically require a temperature of at least 15°C for normal germination. Therefore, it's best to start planting when the field temperature consistently reaches 12°C. If planted too early, when temperatures are still low, the seedlings will grow slowly, so the age should be slightly longer. Conversely, if planting is delayed and temperatures rise, the seedlings will grow faster, and the age should be shorter accordingly.
The amount of seeds sown should be adjusted according to the age of the seedlings and the ambient temperature. Ideally, the seeds should be sown evenly and thinly, ensuring each seedling receives enough sunlight, air, and nutrients to grow strong. Overcrowding can reduce the light available to the seedlings later on, affecting their ability to photosynthesize, weakening their root system, and making them more prone to disease. Normally, for young seedlings under 20 days old, about 180–200 kg per acre is recommended. For seedlings around 30 days old, the seeding rate should be reduced to 80–100 kg per acre.
Cultivating healthy and vigorous seedlings is the foundation for high rice yields and a key factor in preventing rot. A wet seedling method can be used to grow seedlings at the appropriate age. During the initial stage, irrigation is usually limited to the furrows, keeping the surface moist without excessive watering. This promotes quick root establishment. During the rooting phase, it’s important to manage the water level carefully, avoiding both freezing and overheating. Maintain a proper water level in the paddy while ensuring good ventilation to protect the seedlings from damage.
