摘　　要：采用盆栽试验与化学分析的方法,对甘蓝型黄籽油菜———"渝黄一号"进行了分析。结果表明:(1)增施S或Zn肥和土壤差异对苗期油菜生物量影响达显著性水平;(2)增施S、B或Zn肥,油菜苗期和苔期叶片S、B、Zn含量也相应地增加,对苗期叶片N、P和苔期叶片硫影响达极显著水平;(3)土壤差异,对叶片苗期吸收P和苔期吸收K、S的影响达显著性水平。By pot experiments and chemical analysis, yellow-seeded rapeseed (Brassica napus L.)—'YU-yellow NO. 1' was studied. Results showed that : (1) effect of subjoining fertilizer of S or Zn and soil diversity were very significant on the weight of plants in the shoot stage of rapeseed; (2) the content of S, B, Zn in leaves was increased accordingly by subjoining S, B or Zn fertilizer, moreover effect of which were significant on N and P of leaves in prophase , and S content in anaphase; (3) effect of diversity of soils was significant on P of leaves in prophase , and K, S content in anaphase.
