At the seedling stage, combine soil, apply 25-30 kg of 50% calcium cyanamide granules per acre, and apply soil after cultivation to protect the seedling root from root tuberculosis. During root elongation of the radish root, an aqueous solution of 800 times Bacillus subtilis, or 800 times 50% aqueous solution of pentachloronitrobenzene, or 600 times 50% aqueous solution of sodium propionate, or 1000 times, is applied to the roots every 10 to 15 days. 25% fludioxonil solution, or 1,000 times 30% Famylline solution, or 600 times 47% spring thunder Wong copper aqueous solution, or 1000 times 25% methyllithophoric acid solution for prevention and control, continuous shower 2~3 Secondly, evenly soak the soil around the roots of the radish plant, and it is advisable to completely penetrate the soil around the roots without flowing out.
