1987—1993年试验、示范表明:在亚热带北缘向暖温带过渡的生态条件下,秋冬型萝卜成株繁殖,以冬季收获时切留10em长樱,随收随栽,封土与切口平方法最好,比冬贮春栽增产114.4％;比冬季收获时切留5cm长樱,封土与肉质根肩部相平的栽法增产68. 02％。其差异均达极显著水平,且年度间产量稳定,是成株种子生产的一项高产稳产技术措施。 From 1987 to 1993, the experiment showed that in the ecological conditions of the transition from the northern subtropical zone to the warm temperate zone, the autumn and winter radish plants propagated in adult plants. When the harvest was completed in winter, 10 cm long cherry trees were planted. 02%. Compared with winter storage spring planting yield 114.4%; than in winter when harvesting cut 5cm long cherry, sealing soil and fleshy root shoulder planted yield 68. 02%. The difference reached a very significant level, and the annual output is stable, is the adult seed production of a high yield and stable technical measures.
