First, use high-quality varieties and new seeds. Choosing radish varieties with dense roots and high dry matter content is essential for producing premium quality radishes. This requires the use of fresh, high-viability seeds rather than old or obsolete ones. Radish seeds have weak viability, and if planted in compacted soil or in areas with stones, bricks, or agricultural plastic debris, it can restrict root growth, leading to deformed or twisted roots. Additionally, selecting varieties with dense roots and high dry matter helps prevent internal rot and heart failure, ensuring better yield and quality.
Second, proper site selection, crop rotation, and land preparation are crucial. Choose deep, loose, and fertile soils suitable for growing cruciferous crops like cabbage, radish, and cauliflower. Deep plowing and fine soil preparation help avoid soil compaction, remove hard objects such as stones and bricks, and eliminate plastic waste. These practices not only promote healthy root development but also reduce the occurrence of misshapen roots and diseases like black rot, improving overall crop performance.
Third, implement rational fertilization based on the plant's growth stages. Balanced nutrient application is vital to maintain high-quality radishes and achieve good yields. Key points include:
- Ensure organic fertilizer is fully decomposed. Using fresh manure or undecomposed compost can burn roots and harm young plants. Moreover, during the growth phase, excessive microbial activity may consume too much oxygen, leading to dark red or black hearts in the radishes.
- Maintain a balanced fertilizer regimen. Apply approximately 6,000–7,000 kg of organic fertilizer per acre, along with 10 kg of DAP and 3–5 kg of potassium sulfate as base fertilizer. During the seedling stage, top-dress with 5 kg of urea per acre. At the rosette stage, apply 8–10 kg of urea per mu. During the rapid root expansion phase, add 5–8 kg of urea, 10–15 kg of DAP, and 10 kg of potassium sulfate per mu. Excessive nitrogen at high temperatures can make radishes bitter, so it's important to balance nutrients, increase organic and phosphorus-potassium fertilizers, and avoid over-application of nitrogen. This reduces bitterness and promotes straight, high-quality roots.
Fourth, practice scientific watering to prevent cracking, pungency, and internal discoloration. Keep the soil consistently moist during germination, and water immediately if the soil becomes dry after sowing. Once 75% of the seeds have emerged, give a light watering to ensure uniform seedlings. During the early growth stage, water sparingly to avoid stunting growth or causing stress that could lead to virus diseases under high-temperature conditions. Ensure proper drainage to prevent waterlogging. As the roots develop, provide adequate water to support fleshy root expansion and prevent cracking. Stop watering 5–7 days before harvest to improve flavor and quality. Use clean, flowing water or well water, and avoid using sewage or stagnant pond water to maintain hygiene and prevent disease.
