Key points of radish cultivation:
Xinmei radish likes cold climate and needs plenty of sunshine. In most areas of our province, the most suitable sowing date is from late September to early October of 10, and sandy loam with deep soil layer, rich organic matter, good drainage and irrigation, water and fertilizer conservation, slightly acidic or neutral (pH 5.5 ~ 7.5) should be selected for planting. The demand of radish for nutrients is potassium, followed by nitrogen and phosphorus. Therefore, attention should be paid to increasing the application amount of potassium fertilizer in cultivation.
Before early autumn 1 ~ 2 days, the plant spacing is 20cm× 50cm, the sowing amount per mu is 0.5kg, and about 5000 ~ 5300 seedlings are left. Watering should be less in the small seedling stage; Proper water control before "broken belly" to promote root development; The fleshy roots grow in a long period, and the water must be sufficient and uniform; The roots should be properly watered in the late growth stage to prevent hollowing. Generally, topdressing is 2 ~ 3 times according to the growth situation, and ammonium sulfate is per mu 10 ~ 15 kg each time; Top dressing plant ash in the peak growth period should be sown in the field after watering, with an area of 100 ~ 150kg per mu. In the middle and late period of radish growth, it is necessary to remove the old yellow leaves frequently to facilitate ventilation. Radish harvested in the first frost can be stored until April of the following year.
