萝卜为二年生植物,第一年为营养生长阶段,先形成叶簇和肥大的肉质根。第二年进入生殖生长阶段,抽薹开花,完成由种子播种到种子成熟的生长周期,要获得丰产优质种子必须搞好母根培植。一、选整结合施好基肥萝卜对土壤的适应性较广。为了获得高产、优质的母根,仍以土层深厚、疏松、排水良好,比较肥沃的沙壤土为佳。培植母根的土地要求在前一年冬进行深耕,一般深耕20～30厘米,翻耕时期,前茬收获后应及时早耕,晒土,改善土壤理化性状,减少病虫危害。深耕必须与增施基肥相结合,才能达到预期的增产效果,应以基肥为主,追肥为辅,一般亩施熟化厩肥2500～5000公斤,播种时施过磷酸钙7.5～10公斤作种肥。这样才能
Radish is a biennial plant, the first year of vegetative growth stage, the formation of leaf clusters and hypertrophy fleshy root. The second year into the reproductive growth stage, bolting and flowering, to complete the seed sown to the seed mature growth cycle, to obtain high yield and quality seeds must do a good job root cultivation. First, the election combined with good base fertilizer radish adaptation of the soil is broader. In order to obtain high yield, high quality root, still soil deep, loose, well drained, more fertile sandy loam is better. Cultivation of mother root land required deep plowing in the previous winter, generally deep plowing 20 to 30 cm, during the tillage, the former crop Harvest early tillage, soil, improve soil physical and chemical properties, reduce pest damage. Deep plowing must be combined with the application of basal fertilizer in order to achieve the expected yield-increasing effect, should be mainly based on basal fertilizer, supplemented top dressing, general Mushi Shi 2500 ~ 5000 kg of manure, silage calcium phosphate 7.5 ~ 10 kg as seed fertilizer. So as to
