Due to the small size of rape seeds and their high germination rate, seedlings often emerge densely, leading to overcrowding, poor nutrient absorption, stunted growth, and weak stem development. These weak seedlings are not resilient, appear pale, and often die after transplanting in Daejeon. They are prone to lodging and result in lower yields later on. A major cause of this issue is over-sowing during the initial planting stage, which leads to excessive density and elongated, weak seedlings. To prevent this, proper sowing techniques and careful management are essential for healthy rape seedlings. First, controlling the sowing amount is crucial. The general ratio of seedbed area to field area is typically around 1:5, meaning that for every mu of field, about 0.2 mu (two tenths) of seedbed is needed. The seeding rate per mu of the seedbed is usually kept at approximately 0.5 kg, or 100 grams of seeds per mu. In practice, the sowing rate can be adjusted based on various factors such as seed size, sowing time, germination rate, land preparation quality, soil moisture, and pest control. For instance, if the seeds are small, sowing is done early, the germination rate is high, the soil is well-prepared, and there are fewer pests, you can slightly increase the seeding rate. However, the seeding rate should generally not exceed 0.6 kg per mu of seedbed to avoid over-crowding. Second, timing the thinning of seedlings is equally important. To ensure even distribution, seeds should be mixed with fine soil before sowing. After the seedlings emerge, it's essential to perform weeding and thinning at the three-leaf stage to prevent overcrowding and leaf overlap. This helps promote uniform growth and stronger seedlings. By maintaining strict management practices, farmers can cultivate robust seedlings, laying a solid foundation for higher yields in the future. Overall, proper sowing and timely management are key to producing strong, healthy rape seedlings. With attention to detail and consistent care, farmers can significantly improve the quality of their crops and achieve better results in the long run.
