The main roots of the radish grow rapidly during the early stages, causing the outer cortex to harden while internal cells develop more slowly. When there is sufficient rainfall during this swelling phase, the secondary xylem parenchyma cells expand quickly, and the pericarp hardens. However, if the swelling cannot keep up with the pressure, the outer skin may crack, leading to cracked roots. To prevent this issue, it's important to maintain even watering throughout the main root growth period. This helps ensure consistent development and reduces the risk of cracking or uneven growth. Another common problem in radishes is the "bifurcation" or splitting of the roots. This occurs when the lateral roots grow instead of the main root. Several factors can contribute to this phenomenon: poor soil quality, shallow soil layers with many stones, or excessive nutrients that encourage lateral root development. Additionally, undecomposed organic fertilizer can generate heat that damages the main root’s growth point, prompting the growth of lateral roots. Overcrowding due to dense planting or improper thinning can also cause the main root to bend and split into lateral roots. Finally, damage to the main root during weeding or other agricultural activities may lead to a forked root structure. To avoid bifurcation, choose deep, loose, and fertile soil for planting. Ensure proper cultivation practices, use fully decomposed organic fertilizers as base fertilizer, and plant seedlings at the right time to allow for adequate spacing and healthy root development. During autumn, radishes are prone to issues like high temperature and drought, especially if the soil dries out and then becomes wet again. Planting too early or harvesting too late can also lead to problems such as cracking or poor quality. For optimal radish cultivation, select loamy soil with a deep layer that is loose and rich in nutrients. After the radish has started to “break belly†(a stage where the root begins to swell), balance water and fertilizer to avoid extreme dryness or moisture. Harvest the radishes once the main root has fully developed to ensure the best quality. Black heart and black skin are two common issues in radishes. The first is caused by black rot, which leads to dark spots inside the root, often with dry, rotten tissue and a hollow center. The second cause is the presence of soil compaction or undecomposed organic fertilizer, which can result in blackened internal and outer tissues. To manage black rot, plant on time and avoid continuous cropping. Do not plant in low-lying areas where water tends to collect. Apply streptomycin at a concentration of 72% at a rate of 3 times, every 7–10 days, and spray 3–4 times for effective control. Additionally, improve soil structure through proper tilling and apply well-decomposed organic fertilizer as a base to prevent soil compaction and nutrient imbalance.    Machined Parts Cost,Hardware Machined Parts,Cnc Machining Workpiece,Brass Precision Machined Parts Dongguan Jiufukai Hardware Products Co., Ltd , https://www.jfkspring.com
